Experimental “Power BEV” 5 Series achieves 100+ hp more power than the M5

BMW Group trial vehicle “Power BEV”: #NEXTGen19.

Quote:
Munich. The BMW Group trial vehicle “Power BEV” presented during #NEXTGen explores what is technically possible. The vehicle is fitted with three fifth-generation electric drive units and has a maximum system output in excess of 530 kW/720 hp. This enables it to accelerate from 0 to 100 km/h (62 mph) in comfortably under three seconds.

The development team’s aim here was to build an experimental vehicle which impresses not only with its longitudinal dynamics but also in terms of lateral dynamics. Indeed, as drivers would expect from a BMW, it has been designed not only to be fast in a straight line but also to put a smile on the driver’s face thorough keenly taken corners.

To this end, the chassis and powertrain engineers worked together particularly closely to maximise the car’s performance. Key to its dynamic attributes is that the two electric motors at the rear axle are controlled separately. This brings e-torque vectoring into play, which enables maximum drive power to be translated into forward propulsion even in extremely dynamic driving manoeuvres.

The result is more effective and precise than with a limited slip differential, because actively targeted inputs are possible in any driving situation. By contrast, a limited slip differential always reacts to a difference in rotation speed between the driven wheels.

The drive system comprises three fifth-generation drive units, each of which brings together an electric motor and the associated power electronics and power take-off within a single housing. One is mounted at the front axle and two (a double drive unit) at the rear axle. Another notable aspect of this generation alongside its eye-catching power is that it is entirely free of rare earths. An electric motor of this type will make its series production debut in the BMW iX3. The iX3 will only have one motor, though, rather than three.

A current BMW 5 Series production model serves as the donor car for the Power BEV. Integrating a drive system of this type into a production car represents a serious technical undertaking, but it has been achieved here with absolutely no restriction in passenger compartment space. This makes it far easier to assess this drive concept alongside alternatives.

It has also allowed the engineers to look even more effectively into the possibilities opened up by two separately controllable electric motors at the rear axle with e-torque vectoring.

And that means, in future series-production vehicle projects, the right technology can be selected for the model at hand. Customers will therefore be provided with the most appropriate technology for their choice of vehicle concept.
Power BEV G30 5 Series Test Vehicle

Could be an interesting combination to make an M car, inline 6 up front, and two electric motors at each wheel to add AWD, could produce some good results

I've been asking this for awhile but does that mean the iX3 is two wheel drive only? Because it's DOA if that's the case.

Which wheels do you envision being powered by each of those power sources? If the ICE is up front then the electric motors are out back, correct? So you either have the ICE powering the front wheels and the electric motors powering the rear wheels (like the Active Tourer and Grand Tourer models, neither of which are M-like), or you have some convoluted driveshaft system transferring power from the ICE up front to the rear wheels, and from the electric motors out back to the front wheels.

Assuming you didn't envision the ICE up front powering the rear wheels and the electric motors also somehow up front powering the front wheels (which I imagine would be a packaging problem, and certainly not ideal for weight distribution), and you don't want to just go full electric with three or four electric motors and no ICE, then the most logical layout for the car would be to mount the ICE mid or rear, and put the electric motors up front. You could even put two motors up front for the front wheels, plus a third electric motor between the ICE and transmission for the rear wheels.

Basically, you'd have the i8 M that everyone wanted BMW to build, and they finally sort of did with the M Next concept.

Don't think an ICE was mentioned in the article at all.

Yes it will be quicker but what about driving dynamics? Where's the fun without a screaming engine in the front?

If you have a manager, this car is probably not for you.

Please give this brochure to your manager.
