German company Artega unveiled at the Franfurt Motor Show its 250-mile (400 km) electric roadster – the Scalo. The vehicle was developed in cooperation with paragon AG and its subsidiary Voltabox, who recently opened battery facility in Texas.

Artega hopes to attract consumers with its very high level of performance, and will launch small-scale production of 12 units, available for some €170,000 (over $190,000), according to some reports.

Artega Scalo (see full specs below), with Voltabox’s 37 kWh lithium-ion battery and two electric motors (390 kW peak) powering the rear wheels, will accelerate from 0-60 mph (nearly 100 km/h) in 3.6 seconds. Top speed is 155 mph (250 km/h).

We are quite confident that 250 miles at 37 kWh is more PR than real-world result, although still this car could be interesting for someone seeking a more unique, sporty EV.

Artega offers an option to increase the efficiency of the motors from 95% to 98% (at 6,900 rpm) and separately power electronics from 93% to 98.8% by using special silicon carbide transistors. This high-tech package appears in the offer just as an demonstration of technology.

The other thing is use of high-performance capacitors (SuperCaps) to eliminate current surge from the battery during acceleration or recuperation, which is by the way adjustable by the driver by switching paddles on the steering wheel.

One of the largest difference from the Tesla Roadster is charging capability – 64 kW DC in less than one hour or two hours using common 22 kW charging points in Germany. Slow 10 hour charging at 16A is possible as well.

The New German Electric Sports Cars

The time is ready for an Artega sports car with a purely electric drive. The new German
electric sports car Artega Scalo entices as a direct successor of the Artega GT by visual
refinement and many technical world novelties. It is built in a small series of twelve exclusive
vehicles to order.

The idea of developing an Artega as an electric sports car is as old as the brand’s history.
Consistent light-weight construction and the modular construction of the chassis make the
Artega platform perfect for electric drives. Three prototypes have been built by 2012, but not
made it for serial production due to their design.

The purely electric Artega Scalo founds a new tradition. In future, the vehicles of the Artega
brand will bear the names of famous racing stallions. Scalo is the first – he was a very special
Westphalian stallion, Galloper of the Year in 2010 and trained very near the head office of
Artega.

Technology from aerospace

The Artega Scalo has two Voltabox rear-mount high-performance electric motors with a total
output of 300 kW (peak output 390 kW) and a 575 ft-lb. It thus outdoes the performance data
of its predecessor. The Artega Scalo accelerates from 0 to 60 mph in 3.6 seconds and reaches an
electronically limitedmaximumspeed of 155mph.

The two electric motors use the latest technologies right from aerospace and drive the rear axle
via a single-stage central gear. Targeted torque vectoring ensures maximum longitudinal and
cross-dynamics with the demand-oriented distribution across the drive wheels. The motor mass
is only 66 lbs each, which leads to an outstanding performance density of 2.3 kW/lb. The
maximum motor speed is at 12,500 rpm, the maximum efficiency at 6,900 rpm is up to 95%.
On request, a version with an outstanding efficiency of 98% is available.

The Voltabox high-efficiency machines are supplied and controlled via two newly developed
inverters with an efficiency of up to 93%. A version with special silicon carbide transistors even
achieves amaximumelectrical energy conversion of 98.8%.

The energy storage also offers a global novelty. For the first time, the Artega Scalo offers a hybrid
system of state-of-the-art battery modules with actively thermally controlled li-ion cells on
nickel-manganese-cobalt basis, combined with perfectly customized high-performance capacitors (SuperCaps). For recuperation, the SuperCaps recharge quickly at first; at acceleration,
the capacitors will discharge first. This constellation increases acceleration and extends the
range. The recuperations system can be adjusted four-fold by the driver by switching paddles at
the steering wheel.

Strong range of up to 250 mls

The li-ion models are distributed between two systems that are crash-protectedly integrated
into the vehicle structure. The capacitors placed in the centre of gravity also ensure best weight
distribution. The Voltabox thermal and battery management is fully integrated and functionally
intrinsically safe according to DIN/ISO 26262.

The installed battery capacity is in excess of 37 kWh, the nominal voltage is at 411 Volt. For up to
10 seconds, as much as 385 kW electrical output can be demanded. The Artega Scalo has a range
of up to 250mls.At a charge status below25%, the power output is limited to 125mph atmost for
the sake of a better remaining range, however.

The battery set has its own cooling circuit. The power electronics and the two electric motors
have a second shared cooler. This way, all system components work at their respective best
working points.

With a 64 kW DC quick charge, it is possible to charge the battery completely in less than one
hour. The maximum charge output of the Voltabox on-board charger at the three-phase current
connection is 22 kW, which corresponds to a charging duration of approx. two hours. At the
AC grid with a 16 A household socket, it takes approx. ten hours.

Large storage volume and beautifully shaped wheel rims

The new German electric sports car has a storage volume of 8.8 cft that are distributed
among the front trunk and the space behind the seats. The empty weight of this vehicle,
including batteries is at 3,494 lbs.

The Artega Scalo has forged central closure rims in a dedicated design (8.5“x 20” front, 11“x 20”
rear) and tyres sized 245/35 x 20 resp. 295/30 x 20. The rim mass in front is only 21.3 lbs and at the
rear 24.4 lbs. The installed Brembo brake callipers (6 pistons front, 4 pistons rear with separate
calliper for the hand brake) with two-part brake discs reflect the brand’s experience in racing
sports.

The 30kwh leaf weighs less, has 81% of the battery capacity and is EPA rated for only 42% of the miles (107 vs. 250)? Scalo customers are in for a BIG surprise! Expect 132 miles out of a 37kwh battery in reality.

arne-nl

It’s the aerodynamics that is more important. And by the looks of it, this car is much better than the LEAF.

Besides, if this thing has a supercapacitor and 4wd then regenerative braking is much more capable and efficient, greatly reducing the weight penalty. And how much extra weight are we talking about? ~60 kg, Almost negligible.

Anti-See Through

Sorry, I don’t buy those answers. Not for a second. If a LEAF had a 37 kWh battery, it would probably do around 120 miles.

Granted, as you say this car is more aerodynamic and will incorporate superior regeneration features, but we’re still talking MORE THAN DOUBLING the range you’d expect from a typical car with a 37 kWh pack.

For aero/regen enhancements alone to double the range you could go on a small battery pack, you would have thought Nissan had tried and done it already, wouldn’t you? The truth is, drag coefficient improvements and regeneration improvements are not enough – even combined – to save 120 miles by themselves. Regen already accounts for a small portion of energy recaptured, so even if Artega’s regen system is 600% more effective than the LEAF’s, combined with reduced drag, that STILL wouldn’t be enough to magically conjure an additional 120 miles when we all know the REAL crux is the batteries.

arne-nl

“but we’re still talking MORE THAN DOUBLING the range”

No, we’re not talking MORE THAN DOUBLING the range

The 107 miles range for the LEAf is EPA.

The 250 miles claimed is NEDC (since they’re a European company).

The 30 kWh LEAF is 250 km NEDC. So that is 61% more range from a 23% larger battery.

Read my comment below and you’ll understand better.

martinwinlow

Cd … “And by the looks of it, this car is much better than the LEAF” I bet it isn’t!

See Through

Great to see the pro-Tesla and anti-everything else trolls going up in fumes here 🙂

Anti-See Through,
Your name sucks 🙁

The Woodster

Personally, I love Anti-See Through’s name.

Rick Danger

“Roadster?” Ahem.

Someone out there

A roadster is a type of car. It’s not something Tesla invented.

Anti-See Through

??? Sorry if I’m confused but I didn’t see him claim a roadster was exclusive to Tesla so why are you correcting him?

John in AA

Yeah, I took the comment to mean “um, a roadster is an open-top car, and that ain’t open-top”.

Rick Danger

Exactly John, and thank you Anti, someone is obviously “way out there” 🙂

jelloslug

250 miles is a wild assumption with a battery that small.

Jerico

I think the 250 mile range is NEDC based so it’s much less but, even then, such a range for a 37 kwh doesn’t seem right.

carcus

That’s a full on electric panty dropper right there.

Kaleb

Yup, but it won’t stop the good people of this site to criticize every aspect.

Josh Bryant

I’ll bite…

Why does it have exhaust pipes styled into the rear?

Looks like a good Roadster replacement if it had about double the kWh in the pack.

I love the supercap/battery combo. That would be the ultimate in a PHEV/REx setup.

Yoda

Those exhaust pipes are air ducts… Notice they are the same color and style as the air ducts on the front and side…

BraveLilToaster

They’re still stupid. An EV doesn’t need exhaust pipes just like it doesn’t need engine sounds. But I’ll bet they’ll add those too.

Robb Stark

Good grief, they are not exhaust pipes.

They are air ducts that could be for aerodynamics or to cool the battery.

They are not exhaust pipes.

See Through

This is an awesome looking car! No one really needs 250+ miles even with aTesla, as no one (except a few nuts) really uses these cars for going long distance. The range of this car is more than enough for most driving. The question is, what’s the price going to be? I think this will blow people away if priced right and done right.

Anon

Just because you prefer to stew in your Mom’s basement, does not mean others would benefit from a longer range BEV…

R.S

why NMC li-ion batteries? Why not NCA? I would bet they also use pouch cells. Apart from the motors, which sound very promising, the drivetrain isn’t really thought trough. If they used Tesla like cells, they could easily boost the kWhs to 70, without adding any mass. But a sports car with a realistic range of 150 miles? Thats not even as good as the 2008 Tesla Roadster. And if a 8 year old (cheaper) car beats you, you have done something wrong.

Bone

You are way off. NCA has about 20% higher specific energy than NMC, so it would be about 42 kWh with similar weight NCA.

Maybe they want the better safety and life span of NMC.

arne-nl

Many are dismissing the range as a PR stunt or WAG. Not too fast.

First of all, this is a German manufacturer and it will be NEDC.

Going by a simple calculation, the LEAF with a 37 kWh battery would do 308 km NEDC.

Then add improvements over the LEAF: better aero, high power and efficient regeneratoive braking (4wd + supercapacitor), 98% efficient motor and silicon carbide power electronics (that is solar car grade, don’t forget to follow the 2015 World Solar Challenge by the way).

Unknown is if the 37 kWh is nominal capacity or usable capacity. There you can find a further advantage over the LEAF.

If they’re not bluffing about the motor/electronics efficiency, it doesn’t at all seem that impossible to me.

msrural

By my reading, this car is not 4wd. It says 2 motors and rear wheel drive. I assume 1 motor drives each rear wheel. Therefore, they’re not getting 4 wheel regeneration capacity.

arne-nl

When I saw ‘two motors’, I automatically thought of the Tesla setup.

Rich

“The two electric motors use the latest technologies right from aerospace and drive the rear axle via a single-stage central gear.”

2 motors on 1 central gear. I assume this means there’s no limited slip or it’s mechanical.

If it’s the very inflated NEDC rating, then the manufacturer quoting that in advertising does qualify as “a PR stunt”. 🙂

Pushmi-Pullyu

Dear Artega: Tesla called. They want their Roadster back. And remove your logo from it before you return it.

John in AA

And will Tesla be putting the original badging back on it before they return it, or does Lotus have to take care of that?

Pushmi-Pullyu

Ouch! Touché, sir.

🙂 🙂 🙂

But Tesla did pay Lotus. I rather doubt Artega paid either Tesla or Lotus for the design.

Rick

It reminds me of an early Mitsubishi Eclipse.

Speculawyer

It is amazing how many Tesla competitors have been springing up. These guys. A couple different Tesla competitors in China. Apple. Some other stealth EV start-ups in Silicon Valley. All the German sports sedan makers now going hard electric.

Imitation is the sincerest form of flattery.

RexxSee

And how come good ranged fast charging electric cars come only from little companies, even garage fiddlers, when our “big boys” have 1000 times the resources to do it faster, massively at better prices?
Could it be they don’t want to?

Speculawyer

The “big boys” didn’t believe a market existed for an expensive large batteried EV. They were WRONG. And they are now scrambling to catch up.

RexxSee

Well I guess they knew it all the time, they are leagued in a cartel, protecting their best friend Big Oil and their own very lucrative ICE car business, and didn’t expect such a bold and brave lil company to come out of nowhere and move their big corporate a$$e$.

What do you expect? that they will make a press conference to announce they don’t give a damn about climate change as long as they make a lot of profit?

Go Tesla!

The Tesla Roadster is sincerely flattered. Very sincerely.

Speculawyer

What is with the air scoop behind the doors? Why?

Koenigsegg

Fun Fact: Henrik Fisker designed this car.

Anon

That would explain the touches of Fugly in the Scala. But I *DO* like the Coupe version, a lot. Much cleaner and there is no silliness like the front retracting whisker air scoops. Makes me think of some kind of weird waxed mustache worn by Detective Poirot.

Rich

Interesting. Even at 200 EPA miles per charge, this would be 5.4 miles/kWh. That’s cool. 200 mile range with only a 37kWh battery pack is encouraging. It would be great if those improvements make it to the lower priced BEVs. I couldn’t afford a car at $190K, but another competitor in the space is welcome.

jelloslug

That would be 37 kw of USABLE battery, not a 37 kw battery.

Mister G

How did they manage to install a battery manufacturing facility in TX? I thought batteries leak.

Art Isbell

They only leak in San Antonio, so this battery manufacturing facility must be somewhere else in Texas.

Bill Howland

I wish mitsubishi would take their very low-cost roadster and put a SMALL motor in it with a big battery.

Rather like the Karman-Ghia VW from decades past, in that it had either a 36 or 40 hp engine in it, but was still fun to drive.

Paying a fortune for an electric car that you can’t drive anywhere isn’t my idea of fun.
