BMW 3 Series eDrive Plug-In Hybrid Revealed – Launch Scheduled For Early 2016

NOV 27 2014 BY STAFF 14

BMW has taken the wraps off its latest plug-in hybrid vehicle, a 3 Series eDrive, which utilizes BMW’s award winning TwinPower Turbo technology and an 8 speed transmission that eschews a torque converter for an electric motor.

The new 3 Series plug-in hybrid will exhibit the positive traits of the X5 plug-in hybrid, but to a much greater degree. With 245 HP and 295 lb-ft or torque on tap from the combined IC and electric motors, acceleration should be brisk – rivaling six cylinder versions of the car. Even more impressive is the fuel economy – BMW is quoting 2L/100 km, or 140 MPG (Imperial gallons). US EPA MPG might be in the 100 MPG range.

Outstanding flexibility, which means it can be integrated in a wide range of different vehicle concepts, makes rapid deployment of this plug-in hybrid drive technology in the BMW model range a feasible and realistic proposition. The BMW 3 Series plug-in hybrid prototype provides a first taste of the extra- efficient driving pleasure which the world’s most successful premium sedan will offer.

Combining a four-cylinder TwinPower Turbo petrol engine from the new Efficient Dynamics engine family with an electric motor, the BMW 3 Series plug-in hybrid prototype offers standards of sporty performance on a par with a conventionally powered BMW 3 Series six-cylinder model, combined with a significant reduction in fuel consumption. Its plug-in hybrid drive system has a combined output of approximately 245 hp and maximum combined torque of approximately 400 Newton metres (295 lb-ft). These figures, together with the substantial extra acceleration provided by the electric motor’s boost function, bring a sharp and intensely dynamic dimension to everyday motoring. Average fuel consumption and CO2 emissions are approximately 2 litres/100 km (140 mpg imp) and 50 g/km respectively. In all-electric mode, the prototype is capable of a top speed of 120 km/h (74.5 mph), and has a driving range of approximately 35 kilometres (22 miles).

Plug-in hybrid system in the BMW 3 Series Sedan: ideal platform, superior drive components, maximum efficiency.

The BMW 3 Series Sedan provides the ideal starting point for developing an exceptionally dynamic and fuel-efficient plug-in hybrid model. The conventional combustion-powered models already set standards in the mid- sized premium segment with their blend of sportiness and frugal fuel consumption. This is down to factors such as intelligent lightweight design, best-in-class aerodynamics and an extensive range of standard-specification BMW EfficientDynamics technologies.

The internal combustion engine used in the BMW 3 Series plug-in hybrid prototype is based on a TwinPower Turbo four-cylinder petrol engine that has already twice been voted “International Engine of the Year”. Its hallmarks are sporty performance, smooth and refined running and exceptional efficiency. The plug-in hybrid prototype also features an electric motor and power electronics which are directly based on the BMW eDrive technology of the BMW i3 and BMW i8 models. The motor is powered by a lithium-ion battery which, together with the battery management system and high-efficiency direct cooling system, are likewise rooted in the experience and know-how amassed during development of the BMW i models. The battery can be recharged at any household power socket and is mounted in a particularly crash-safe position underneath the load compartment.

The power electronics form a single integrated system that drives the electric motor, via a liquid-cooled inverter, manages the energy flow from the high- voltage battery to the onboard electrical systems and provides centralised control of hybrid-specific functions. The drive torque from engine and electric motor is supplied to the rear wheels of the BMW 3 Series plug-in hybrid prototype via an 8-speed Steptronic transmission which – as on conventionally powered BMW models – makes its own additional contribution to the efficiency of the overall drive system.

Nowadays, the potential integration of a plug-in hybrid system is taken into account at all stages in the development of new models of the BMW and MINI brands. Amongst other things, this ensures that future hybrid versions offer the same level of practicality as the base models. For example, there is only a minimal reduction in boot space in the BMW 3 Series plug-in hybrid prototype compared with a conventionally powered BMW 3 Series Sedan, while the interior configuration possibilities – e.g. with the folding rear seatback – are unchanged. The simplicity with which the 8-speed Steptronic transmission can be integrated into the plug-in hybrid system is a further benefit of this flexible, forward-looking development strategy.

Intelligent energy management with adaptive powertrain control.

Like the current production models, the BMW 3 Series plug-in hybrid prototype is fitted with a Driving Experience Control switch, which is mounted on the centre console. This can be used to select different vehicle settings to suit varying requirements and situations. Three different modes are available: COMFORT, SPORT and ECO PRO mode. Each features different suspension settings, different shift characteristics for the 8-speed Steptronic transmission, and a different hybrid operating strategy.

In COMFORT mode, which perfectly balances comfort and efficiency on the one hand with typical BMW dynamic performance on the other, the electric motor’s control strategy is geared to relaxed, fuel-efficient driving. In tandem, the electric motor and internal combustion engine can also deliver high levels of power and performance when required. SPORT mode, meanwhile, is aimed at maximised performance, harnessing the full combined output of the engine and the electric motor. In this mode, engine and motor are both on stream at all times, ensuring instantaneous response to all accelerator commands. Finally, in ECO PRO mode, the accent is on harnessing the full efficiency potential of electrification. Intelligent hybrid functionality allows the electric motor and internal combustion engine to work in tandem to maximise overall system efficiency. Efficient energy management is enhanced by variable control of the electric comfort functions such as air conditioning, seat heating and exterior mirror heating, which always operate at the most appropriate power level. This likewise helps to maximise the vehicle’s range.

At the press of a button, the driver can choose between different plug-in hybrid modes. The MAX eDrive mode provides all-electric, zero-local- emission propulsion. Selecting the SAVE Battery mode keeps the battery at a constant state of charge. If the battery is less than 50 percent charged, the charge level is increased. In this way drivers can ensure they have enough power in reserve to operate in all-electric mode on a later, urban section of the journey.

The BMW 3 Series plug-in hybrid prototype also features a special hybrid- adapted Proactive Driving Assistant. Integrated in the navigation system, this system manages the powertrain not only with reference to current battery capacity but also to upcoming route profile, speed restrictions and traffic conditions.

This function marks the most extensive and advanced integration to date of BMW EfficientDynamics and BMW ConnectedDrive. Whenever the navigation system is in operation, the hybrid Proactive Driving Assistant collates all the available information about the upcoming route and relays this to the powertrain controller. This information comprises both static data from the interactive map, for example about speed restrictions and gradients, and also real-time information on current traffic conditions (Real Time Traffic Information – RTTI). The proactive energy management system then breaks the route down into its component parts, including low-speed sections, last- lap sections and gradients, before computing a proactive, route-specific strategy for managing the electric drive power right through to the specified destination.

To compare the 2L/100km (theoretical) with a Volt’s real usage. With my 2012 Volt, I burnt ~70 gallons over 20,000 miles. I was at around 90% EV to gas miles. I reckon that equates to ~0.83L/100km.

Dr. Kenneth Noisewater

I guess I can see the point of having a weak plugin like this, since to get the required electric motor torque you need to have a large enough battery in the first place, and electrification + high-voltage power bus are valid fuel-savers in and of themselves. And getting rid of fuel-wasting torque converters and start/stop is nice.

I’d still rather have an EV tho, even with a range extender.

It’s impressive to see this drivetrain, but it is also way too complex. Car makers do not want to produce what people want. A simple long range clean silent and economical BEV.
They all try to lure us toward hybrids to keep their replacement, maintenace and repair business.

It’s no surprise Tesla’s get such a crazy demand!

Should have used this body for the i3.

Too big and heavy.

I like the “up to 22 miles”, as if that was a performance. Any new model needs at least more then the Volt to be taken seriously.

22 mile range and another RWD vehicle. Sigh.

Well, it’s a mini step in the right direction as it’ll be the first somewhat affordable BMW electrified option with conventional styling. And the MPGe is great

It’ll sell well in areas without much snow, depending on price.

I don’t think the MPGe is realistic, especially for people living in colder climates like you and I JRMW. My Volt is sitting at 2.4L/100km lifetime… I have a hard time believing this will beat it.

Will add my voice too….
Why can’t anyone other than Chevy make a serial hybrid with any kind of meaningful electric range. Take BMW engineering and style with the Volt concept and you would have a “killer app”.

Agreed, or even straight build the i3 system into a 3 series body style and add a normal gas tank. That would be a killer app indeed.

Why no hybrid gives more electric range? Simple, and cynical. Even if the Volt is a regression over the EV1, it is too successful for commuting. So the new models from ICE car companies all have less Range. And even the “new” Volt will be quite the same stuff with ~5% improvement?

BWM has no clue where to put the charging plug. “Let us just put in at a different place on every model.”

Loving all the reference to the X5 PHEV –

ahem, the i is centered around the i8 supercar. Like the Tesla, your $140k is funding the re-invention of the ICE car, one that relies upon electric for 0-10 (and beyond, of course) regen to keep the Teeny-Tiny battery capable of delivering 0-10 nearly no matter what the conditions, therefore an ICE that doesn’t need to grunt anymore – and something that the beloved BMW I6 was never terribly strong at in its heyday (3k RPM made Go).

It’s brilliant, as long as you Wanted to keep an ICE and use E as a cheap supercharger. CO2 drops, with further efficiencies and synergies, should keep their ICE’s within whatever limits EU can hand out through 2025.

i5? Not gonna happen. Discounting the i3 defines my reasoning, BMW doesn’t discount much, and if people aren’t standing in line to buy an i3 at near sticker and more? Ende.
Nuthing new in that brand for a While.

This car is so close to what I wanted after we sold our M5 to get a Volt…a 3 series Volt if you will. Unfortunately, it is still over a year away, will debut on then 5 year old platform, and will have the typical 20 mile range we are seeing in all the PHEVs. I would be willing to be that it also won’t be available in m-sport trim unlike the current ActiveHybrid3 which is…Eco and performance seem to always be viewed as opposites for virtually all EVs save Tesla and the i3 (aka a hot hatch play by BMW).
