China-based automotive R&D company, Techrules, unveiled at the 86th Geneva International Motor Show, range-extending turbine recharging technology, shown in the two seat concept supercar AT96 TREV and GT96 TREV.

Techrules states that Turbine-Recharging Electric Vehicles (TREV) will “revolutionize” the performance and environmental impact of future electric vehicles.

Both models are equipped with a series-hybrid powertrain, with a 36 kW turbine running on either aviation kerosene (AT96 TREV) or natural gas, biogas, diesel, gasoline in case or the more mundane (GT96 TREV).

The turbine works at very high 96,000 rpms and powers generator (6 kW directly powering auxiliary equipment such as the inverters. The 30 kW electrical output from the generator is used to charge the battery pack).

The battery pack is 20 kWh lithium-ion (18650 type), which would be good for up to 150 km (90 miles).

The big surprise is in the motors – because there are six electric motors for four wheels (AWD).

Peak output is 768 kW (1,030 bhp / 1,044 PS), while total range stands at over 2,000 km (1,250 miles).

Quick specs:

  • 36 kW turbine (96,000 revolutions per minute)
  • 20 kWh lithium ion-battery for 150 km (90 miles all-electric range) and over 2,000 km (1250 miles) of total range from 80 litres of aviation kerosene
  • six electric motors for AWD – 768 kW (1,030 bhp / 1,044 PS) system power
  • (0-100 km/h (0-62 mph) in 2.5 seconds
  • 350 km/h (218 mph) top speed
  • curb weight of the development vehicle is 1,380 kg

Geneva, 1 March 2016 – Techrules, a new China-based automotive research and development company, is making its global debut at the 2016 Geneva International Motor Show. It is dedicated to the innovation of new energy technologies to advance the environmental and dynamic performance of EVs as well as the convenience to the user.

It has developed a Turbine-Recharging Electric Vehicle (TREV) system, an all-new patent-protected series hybrid powertrain technology comprising a turbine-generator. TREV combines extensive experience of aviation and electric vehicle technologies with several proprietary technical innovations to deliver unprecedented levels of efficiency and performance, and ultra-low environmental impact.

TREV is a range extender system that uses a micro-turbine to generate electricity that charges a battery pack. The battery powers the motors that drive the wheels. Newly developed battery management technologies enable superior charging efficiency. The high efficiency of the TREV range extender results in a requirement for fewer batteries, saving weight and space.

Techrules is showcasing its ground breaking technology at the 2016 Geneva International Motor Show in a plug-in hybrid range extender TREV concept that represents the first step towards production of China’s first supercar. A development prototype started testing last month (February 2016) at the world-famous Silverstone race circuit in the UK.

Producing peak power of 768 kW (1,030 bhp / 1,044 PS), initial projections indicate blistering performance (0 – 100 km/h in 2.5 seconds; 350 km/h restricted top speed) and a huge range (over 2,000 km). Under plug-in operation, it achieves fuel consumption of just 0.18 l/100 km (1,569 mpg).

Techrules plans to begin series production of TREV technology in a low volume supercar of its own design within a couple of years. It then plans to begin production of higher volume city cars a few years later.

William Jin, the founder and CEO of Techrules, said: “The TREV system is a perfect combination of micro turbine and electric vehicle technologies. It is highly efficient, produces very low emissions and provides an optimal charging solution for electric vehicles.

“We believe it may redefine how the next generation of electric vehicles is powered.”

FURTHER DETAILS

Turbine-recharging electric vehicle (TREV): a revolutionary range extender technology for next generation EVs

TREV is an all-new proprietary, patent protected series hybrid powertrain system. It comprises a micro turbine generator that is inspired by technology commonly used in the global aviation industry and large-scale power generation industries. The turbine drives a generator which charges a battery. This in turn, provides electricity to drive the traction motors. Unlike many previously developed turbine powertrain systems, there is no direct electrical feed from the generator to the electric motors: the TREV system is purely a series hybrid range extender system.

Techrules GT96 TREV supercar concept - studio

Techrules GT96 TREV supercar concept – studio

Air drawn into the micro turbine is passed through a heat exchanger where heat from the exhaust air is transferred to the cold intake air after it has been compressed. Ignition of the compressed and heated fuel-air mixture generates enormous energy which is channelled to at very high speeds to turn the turbine vanes. As this hot exhaust gas is expelled, it passes through the heat exchanger to ensure the heat energy is recuperated and transferred to cold intake air.

Techrules Chief Technology Officer, Matthew Jin, explains: “In the conventional cars that dominated the 20th century, the combustion engine that converts a fuel’s chemical energy into a useful mechanical energy is also the driving engine that turns the wheels.

“Because turbines have always been a very inefficient way to convert chemical energy into useful wheel turning mechanical energy, only a few have tried to use a turbine in the powertrain system, and none have ever succeeded commercially.

Techrules GT96 TREV supercar concept - studio

Techrules GT96 TREV supercar concept – studio

“But, with electric vehicles, an electric motor is used to drive the wheels, which effectively frees the combustion engine to exclusively convert chemical energy into mechanical energy and finally into electric energy. This is a major breakthrough, making it possible for us to use the highly efficient turbine engine as a superb range extender on our vehicles.”

Micro turbines are significantly more efficient than piston engines in range extender applications, because significantly less energy is sacrificed in frictional losses, meaning more of the fuel’s chemical energy is harnessed.

The turbine shaft powers a generator that produces electricity to charge the battery cells. In Techrules’ TREV configuration, the turbine and the generator share the same shaft and rotate at the same speed: over 96,000 revolutions per minute.

The total weight of the TREV range extender system (micro-turbine, inverters, fuel pumps, air pumps, and generator, but excluding batteries and motors) is approximately 100 kg.

TREV system features proprietary innovative technologies for unprecedented levels of efficiency

The TREV system incorporates several new technologies that make it approximately 50 per cent more efficient thanrange extender systems using petrol engines, which dramatically increases the viability of its commercial series production.

The high rotational speeds that the shaft requires in order to draw in the required volume of air means that achieving low friction is paramount to the efficiency of the TREV system.

Techrules employs air bearing technology – a high pressure feed of compressed air – instead of a traditional oil lubricant film to separate the shaft from the bearing. This results in fewer frictional energy losses, since it eliminates parasitic losses of a mechanical bearing. The use of an air bearing system is not unique, but how Techrules uses the air bearing involves genuine world-first innovations.

Techrules GT96 TREV supercar concept - studio

Techrules GT96 TREV supercar concept – studio

Of particular note is that the air bearing is also supported by a magnetic field that allows for precise adjustment of the high speed shaft. Both bearing solutions work together to maintain exceptional stability. The magnetic bearing allowsa far greater clearance between the shaft and its wall lining, which delivers significant advantages for the long-term durability of the system.

This is an especially important consideration in automotive applications of turbine systems because – unlike in stable power generation conditions – the entire assembly must be able to be capable of withstanding volatile operating conditions that result from, for example, vertical shocks from uneven road surfaces and lateral forces in cornering. Techrules’ hybrid bearing system is also more economic to produce, because the built-in extra clearance space reduces the extreme tolerances usually required.

In addition, a new design of internal foil – an intrinsic component within an air bearing – is used for the bearing liner that supports the air pressure and flow. It is made of a new compound material that gives it superior durability. Of equal importance is that the new foil enables the mass production of the bearing liner at the required production tolerances to be achieved at a high volume scale at low cost.

Techrules has also introduced a new and innovative heat exchanger design that is more thermally efficient than conventional designs. A new material has been introduced in the hybrid heat exchanger which greatly increases the efficiency of heat recuperation from the exhaust gases.

The turbine – rotating at 96,000 revolutions per minute – produces 36 kW. Of this output, 30 kW powers the generator, with 6 kW directly powering auxiliary equipment such as the inverters. The 30 kW electrical output from the generator is used to charge the battery pack.

Smart battery management with new charge balancing strategy

The TREV system employs an innovative smart battery management system that optimises the efficiency of battery charging and power balancing between battery cells.

Techrules TREV technology - Battery cells

Techrules TREV technology – Battery cells

In a conventional lithium-ion battery management system, to avoid cells being damaged by overcharging, the cells – which each charge at a slightly different rate – must be balanced as they charge. This balancing is conventionally achieved by actively discharging the cells that are charging more quickly in order to enable the other cells to ‘catch up’. This process sees a proportion of energy wasted during the charging process and increases the time required to charge all cells fully.

To address the shortcomings with this standard industry practice, Techrules has introduced an innovative new charge balancing strategy. The smart battery balancing system harnesses the ‘excess’ voltage in cells that are charging more quickly, sharing their charge with slower-charging neighbouring cells to achieve the required balance. As a result, the entire pack charges more quickly, and there is no energy wasted in actively discharging the best-performing cells.

Techrules AT96 TREV supercar concept studio

The TREV system uses readily available cylindrical 18650 Lithium-Manganese-Oxide battery cells. Techrules is focusing its capabilities on the efficiency of the battery management rather than the battery chemistry itself. Its insight and smart battery management system will be applicable to any future, higher capacity battery technology.

Unlike most EV development programmes, because the TREV system incorporates a series hybrid range extender, Techrules is prioritising power density – the capability of the batteries to deliver peak power – ahead of energy density – the capability of the batteries to hold maximum energy

TREV’s advanced smart battery management system optimises the efficiency of battery charging, reducing the time to charge batteries and reducing wasted energy.

Reduced whole-life environmental impact

TREV technology lowers the whole-life environmental impact of EVs by addressing or avoiding several major shortcomings of current technology.

TREV is capable of delivering an unprecedented range for a series hybrid supercar.

Projections, based on initial testing, indicate that the range of a future production supercar under battery power alone will be up to 150 km. Where charging points are unavailable TREV technology can recharge batteries anywhere, either while underway or when parked – eliminating range anxiety. It is envisioned that this parked recharging process could be completed unsupervised, overnight for example.

Maximum range – based on the battery configuration in the concept supercar presented at Geneva – is projected to be over 2,000 km from 80 litres of aviation kerosene (in urban driving conditions), or a fuel with equivalent calorific value.

Another fundamental challenge to the feasibility of mass adoption of EVs in several markets is the massive draw on the electricity grid that would be impossible to meet within the current grid capacity. If the Chinese market, for example, adopted plug-in EVs, the result would be a massive increase in pollution from coal-fired power stations. And many markets in the western world, too, are precariously close to the limit of the electricity generation capacities of their power generation infrastructures. These markets would not be able to sustain a widespread adoption of plug-in EVs.

With a common core architecture, the TREV system can be tailored to run on one of a variety of fuels. This means that the configuration of the TREV system can be matched to the fuel which is already prevalent in a specific market with a comprehensive supply and distribution infrastructure. As a result, adoption of the TREV system by the fuel supply industry, vehicle manufacturers and consumers requires no major investment in new networks – as with plug-in EVs or hydrogen fuel cells. The TREV system’s turbine has been tested in various guises, with alternative versions running natural gas, biogas, diesel, gasoline and aviation kerosene.

Since the significant uptake of EVs is dependent on the availability of charging point networks, which require major investments in new infrastructure, harnessing the existing fuel distribution infrastructures reduces the absolute reliance on these networks.

The TREV system delivers very high efficiency and very low emissions, and is a sealed-for-life powertrain solution which requires almost zero maintenance throughout the ownership cycle. The only service item is the air intake filter.

Concept is a vision of future production TREV supercar

Techrules is showcasing its TREV technology at the 2016 Geneva International Motor Show in a two-seater all-wheel drive concept supercar. The turbine generator is carried behind the passenger cabin and in front of the rear wheels, making the concept a ‘mid-engined’ electric vehicle.

It is presented in two designs, the AT96 and GT96. These designs – each offering an alternative configuration of the TREV system – are two variations of a vision of how turbine-recharging supercars might look when the technology enters production in China’s first supercar.

‘AT’ refers to ‘Aviation Turbine’, indicative that the turbine is configured to run on a liquid fuel such as aviation kerosene, diesel and gasoline. The AT96 is a vision of a track-focused version of the supercar and features management large rear wing, which provides both straight-line stability as well as downforce to aid high speed cornering.

Techrules AT96 TREV supercar concept - on track

Techrules AT96 TREV supercar concept – on track

The GT96 – for gas turbine – is designed to run on a gaseous fuel such as biogas and natural gas and is styled as a road-going hypercar.

The supercar also incorporates plug-in charging capability for markets where public or residential off-street parking charging networks – ideally powered by renewable energy sources – are in place.

A first supercar development prototype – based on the AT96 aviation turbine configuration – has been produced by Techrules’ specialist vehicle engineering partners in Italy and the UK. Initial testing began in February 2016 at the iconic Silverstone race circuit in the UK.

The range of the supercar concept on plug-in battery power alone is projected to be up to150 km, with a total range of over 2,000 km from 80 litres of aviation kerosene – or a fuel with the equivalent calorific value – with the TREV range extender deployed.

The combined peak output of the motors is 768 kW (1,030 bhp / 1,044 PS) and maximum torque at the wheels is projected to exceed 8,600 Nm (6,300 lb ft). With such power available with such brutal immediacy, the Techrules supercar concept boasts performance to rival today’s hypercars: 0 – 100 km/h in 2.5 seconds; top speed electronically restricted to 350 km/h.

Fuel consumption is projected to be just 0.18 l/100km. With a full charge provided solely by the TREV system, fuel consumption is expected to be approximately 4.8 l/100 km.

Techrules AT96 TREV supercar concept - on track

The kerb weight of the development vehicle is currently 1,380 kg. The target for the future production supercar is a sub-1,000 kg dry weight.

At the heart of the concept is a carbon-fibre monocoque to provide exceptional torsional rigidity and passenger safety. The body structure is also lightweight carbon fibre, including the dihedral doors.

The rear subframe carries the primary range extender components, including the micro turbine generator and direct ancillary systems, as well as the cooling systems for the electric traction motors and battery pack, and the rear motors and inverters.

Under the carbon-fibre body, a longitudinal T-shaped battery back runs down a central spine of the car – providing the same appearance in the passenger cabin as a transmission tunnel would in a front-engine, rear wheel drive car. The battery pack is liquid cooled to maintain an optimal operating temperature for the cells.

The battery pack comprises 2,376 individual 18650 cylindrical cells that use the ultra-safe Lithium-Manganese-Oxide chemistry (LiMn) chemistry with a capacity of 20 kWh usable and with a voltage of 720 V. Thanks to its smart battery management system, the battery pack can be charged by the turbine generator in approximately 40 minutes.

Techrules AT96 TREV supercar concept studio

The supercar concept is driven by six electric traction motors, each weighing 13 kg and each one of which is coupled to its own dedicated inverter. Each front wheel is driven by a single motor, while each rear wheel is driven by a pair of motors.

The primary advantage of using two smaller motors instead of a single larger motor for each rear wheel is packaging efficiency and simpler mounting to the monocoque.

This six-motor layout with independent power feeding each wheel provides an ideal configuration for torque vectoring which is managed by an electronic control unit. Four-way torque vectoring guarantees maximum cornering stability at high speed and eliminates the requirement for complex and heavy mechanical differentials.

With such power and speed available from the accelerator pedal, so is there due consideration for high performance stopping power. Rapid retardation is achieved with 405 mm ventilated discs with six-piston calipers at the front, and 380 mm ventilated discs with four-piston calipers at the rear.

The current plan is for a TREV-powered supercar to be produced and sold in low volumes within the next few years. The low volumes will help Techrules perfect the production process of the TREV system and learn from its performance in real world conditions as it further develops the system for higher volume production.

Introducing TREV technology in its own supercar will also allow Techrules to demonstrate its credentials as an environmentally-friendly technology that can deliver exceptional dynamic performance. As it evolves quickly from an automotive research and development business into a car manufacturer, Techrules aims to lead a symbolic shift by the Chinese car industry towards world-class automotive quality and performance standards.

Following its launch with low volume supercars, Techrules’ will then develop its capabilities to realise its next ambition: the development of the technology for high volume applications including sub-compact and compact (B- and C-segment) cars, to be introduced to the market a few years later.

Techrules – a new company heralding a new dawn for the automobile

Techrules is a Beijing-based automotive research company focused on developing groundbreaking powertrain technology and fuel-efficient and environmentally friendly vehicles.

Its founders believe that future cars should be more efficient, more environmentally-friendly, and with better user experience than what is available on the market today. To achieve this, vehicles need to minimize whole-life well-to-wheel emissions that piston engine and plug-in EVs are failing to make significant progress with.

Techrules is a subsidiary of Txr-S, a research and development company which has other subsidiaries operating in the fields of new materials development, biogas production and aerospace.

  1. M. St. John says:

    Where is the rest of the article?

  2. David Murray says:

    I’ve been wondered for a while why EV’s like the i3 Rex don’t use a small turbine engine. Only thing I can think of is that manufacturers are more familiar and experienced with the traditional cylinder based ICE.

    1. alohart says:

      I’m guessing that even a small turbine would cost considerably more than an ICE engine of similar power because of the expensive materials required to withstand the high temperatures of an efficient turbine. But it would be nice if a turbine could replace an ICE range extender. Maybe turbine costs are becoming more reasonable.

      1. Just_Chris says:

        Gas turbines are not any more efficient than an ICE at small scale, a good turbo diesel generator will be more efficient than a gas turbine below 100 kW (note natural gas can be used in an almost identical engine with no loss in performance). Power to weight is a totally different ball game.

        The thing that confuses me is why have a 20 kWh battery? that most it will output is 80 kW, so 10% of the power. That means you have a 650-700 kW generator with an 80 kW buffer which will probably only be a 30-50 kW load for charging. A flat out drag race will be fine in this car but it will be an absolute dog for almost any normal driving situation.

        When cruising on the freeway you’ll be using may be 15-20kW so how will the GT work? Will it just be idling ready to burst into life when you accelerate? That will work, but will be massively inefficient and probably very difficult to control – think turbo lag x 100.

        1. Just_Chris says:

          I just re-read the article – I think there is something not right here. How can you get 760 kW out of a 36 kW gas turbine and a 20 kWh battery? If they had a really powerful battery (like an LTO battery not a Li-Mn pack) they might be able to get 12 times the storage capacity in power output so a max of 240 kW – how will that give you 760 kW?

          276 kW in, 276 kW out regardless of how big the motors are.

          I think these guys need to hire more boring men with beards and less sexy bimbos with heals.

          Please note I am using colorful language to demonstrate the point that this company needs to focus more on function than form. There are some very attractive engineers and some very intelligent booth babes – in my experience a good proportion are often students. I do not believe that appearance has anything to do with intelligence.

          1. SparkEV says:

            Agree that deliverable power doesn’t add up. But they could be pulling old Tesla: simply add up the power of their motors. Tesla wised up, not sure about these guys.

            Hypothetically, they could have capacitor bank that delivers close to 800kW, if only for a microsecond. Some capacitors I used for work delivered several gigawatts (nano seconds) and fairly small. Again, claiming such on EV would be wrong (or is it?)

            As for 20kWh battery, SparkEV has 18.4kWh battery and 100 kW motor, so it’s not limited to 80kW.

            1. Just_chris says:

              The spark has an nmc battery, that is pretty top end this has a li-mn battery which is not, the spark also has a 100kW motor that may not be the same as 100kW output. I’d love to know what the actual power output of the spark is at 5% soc – if it’s more than 80 kW I’d be surprised. What ever it is it won’t be 650 kW.

              1. Just_chris says:

                Btw I really like the spark and I’d really like this car too if they had been honest about the drive train and specs. If they were honest and sold it as a light weight sports car that was a phev which can run on any waste oil or oily biofuel (which this probably can) then I’d be really excited. They could emphasise the reduced well-to-wheel impact of this car because of its ability to run on less refined fuels but instead they tried to make it a “super car” or a “tesla killer” which is just naff.

              2. SparkEV says:

                SparkEV does put out 100kW. Power going to motor is greater than 100kW. There’s torque/power curve that shows what happens at rear axle (100HP at about 45 MPH).

                As for 5% battery power, MFR don’t advertise power at minimum, but at max or at typical. I’ve seen power at 75% to be the same as 100%, so “typical” would be 100kW.

                You may be right about nmc. But regardless of cell tech, these guys claiming 700HP is probably coming from some other bogus metric, nothing that will result in anything meaningful like 0-60 time.

        2. jerryd says:

          Just, The Lotus 35kw RE only weighed 115lbs and it is 10% of the price and more efficient than this vaporware turbine that would be lucky to be 25% efficient.
          On the car, a very nice job but unlikely to do what they say as with such a top speed and no transmissions, not going to happen.
          Nor will you do even 120mph for long with only 35kw and 20 kwhrs.
          The composites looks excellent. A smarter path would be 60kwhr for a 300 mile range instead of the turbine.
          Though Capstone makes one almost the same as the one mentioned in 30kw for their CHP and garbage methane recovery systems.

          1. Just_Chris says:

            I actually think this could be a good car if they thought a bit harder about what they are doing.

            This is essentially a Leaf or Spark sized battery pack with GT rex. If it was light enough and well balanced it could be quite good fun to drive. If it could run on bio-gas or even if they sold a little gas compressor unit that could be connected to mains gas and used as a home filling station it would be a very interesting concept. You could have an eco-mode that meant that you just drove around until the battery got to 20% state of charge before the GT kicked in and charged to 80% at the GT’s maximum efficiency point or you could have a sport mode where the GT idled until you accelerated hard where the GT could respond dynamically for more power but at hopeless efficiency. I think the GT would need to be bigger to make it competitive with things like the volt or even Tesla’s. The joy of the GT is not the efficiency but the fuel flexibility but if 80-90% of your driving is done as an EV is the efficiency that critical? You could in theory design this car to operate with electricity, liquid fuels and/or gaseous fuels with the hardest bit being designing the fuel tank. This is pretty much how the US army tanks operate with a GT. IMO all of this technology lends its self more to the off-road crowd rather than the EV sports car but like I said above I think they are pitching it wrong – the technology could be quite good fun.

    Yeah the range is in that BULL**** NEDC garbage so real world range on electric is closer to 90 miles, NOT 90 Km.

    1. alohart says:

      Do you mean 90 km rather than 90 miles? With a battery pack about 10% smaller in capacity than that in an i3 and in a heavier car, 90 km is probably close.

      With a range extender generator outputting 30 kW max., this car’s maximum speed would be significantly reduced when the battery pack’s charge has been depleted just as happens in an i3 REx.

    I spent my entire professional life in gas turbines. The micro turbine they are talking about has terrible fuel consumption and it costs more. The only advantage is weight. …then there’s the noise issue and recuperator fouling problems.

    forget it, it’s a DOA concept.

    Good advertising though I must admit 🙂

    1. Bone says:

      Exactly.

      Moreover, with ~100 mile electric range the extender is used for only small percentage of driving, and top notch efficiency isn’t that important. The range extender only needs to be cheap, simple and small enough. Small gas engine fits the bill

      BMW i3 has the right idea. If only it had proper gas tank (6 gallons or so) it would be perfect car for my driving needs.

    2. zikzak says:

      I have the same feeling without working on any of this tech.

      96000rpm, the noise must be terrible. Do you know how much we can expect?

    3. G2 says:

      Exactly, and I thought gas turbines operated best with cooler ambient air for combustion and did everything in their power to avoid injestion of hot air.

      Complete ‘road apples’…

  5. M. St.John says:

    The Volt and i3 really have the right concept. Until batteries are $50/kW it does not make sense to carry batteries to travel more than 150 miles per charge. Burning 10-20 gallons of gas a year is nothing compared to what ICEs burn today in a year.

    Sounds pretty cool, at first.

  7. Mark says:

    Lose the ridiculous spoiler and that’s a damn fine looking car tho!

    1. ffbj says:

      True.

  8. Ed Hart says:

    Lots of stuff here that is not adding up. For sure, a turbine is not likely to be as efficient as claimed…and turbines don’t scale down well, anyhow.
    I would have been very skeptical if they had claimed 120 mpg in hybrid mode. But a claim of 1569 mpg is, well, FAR too good to be true. And add in a 1200 mile range, just to cap it off.
    If any of this was correctly stated, then this would be the only powerplant to be used going forward.
    But…allowing for some misunderstandings, there is obviously some serious money being spent, so let’s see what comes out the other end of the pipe!

    A Chinese version of Homer-mobile super-car. It runs on any old thing. One turbine for liquid and one for gaseous fuels. Why not add a steam turbine which could off the waste heat created by the high-speed turbines? Also the water could be used to help cool the engines.

    It’s like they tried to think of everything they could put into it. Not very minimalist of them. I wonder what KISS translates into in Mandarin.

      “I wonder what KISS translates into in Mandarin”

      It’s something very close to HRYOSS
      (Hey, Read Your Own Specs Stupid! – – Preferably with the help of an engineer, not that wild-eyed sleazebag marketing guy with the big budget and the corner window)

      1. ffbj says:

        Harsh, but I like it.

  10. Kalle says:

    Dident volvo have a prototype with a turbine range extender back in the 90s? They might still hold the patants for it..

    1. Peter says:

      If Volvo held any patents for that, they have most likely all expired by now.
      The Volvo ECC was presented in 1992, that’s 24 years ago now.
      And the term of patents is only 20 years from the filing date in both the EU and the US: https://en.wikipedia.org/wiki/Term_of_patent#Jurisdiction

  11. Someone out there says:

    Holy batmobiles, that thing must be loud!

  12. Kalle says:

    Ah, here is a link to the volvo from 92 https://en.m.wikipedia.org/wiki/Volvo_ECC

  13. PVH says:

    For sure I feel recharged looking at the supercar concept pics and its fine accessories :-).

  14. Bobby says:

    Mazda seems like they should be the one to pick this up i remember driving and Rx 7 years ago
    I am glad that somebody’s testing this I have had many conversations with people on why a rotary motor would be better than a cylinder motor for plug-in hybrid
    But then again cheaper lithium and better charging makes his car extinct before it even happens

  15. Aaron says:

    This car follows Aaron’s law of concept cars: The farther the car is away from production, the farther away from circular the steering wheel is.

    I guess 1000+HP is the new black… all the cool kids are doing it.

  16. Scott says:

    One of the best things about EV’s are the fact that they are nearly silent….a gas turbine?!? Are you kidding? Watch the videos of the guy that put a small military APU in a Suzuki Hayabusa.

    Beautiful! Gorgeous! Oh … the car too 🙂
