BMW goes 'beyond next level' with new EV test rig

Stupendous torque, ground effect and light-up wheels - the Vision Driving Experience has arrived...


BMW, you may have noticed, is starting to generate quite a head of steam when it comes to its Neue Klasse EVs. It started, predictably enough, with the design concepts long ago, but shifted up a gear when M GmbH started talking in detail (via YouTube) about what the forthcoming electric M3 is going to be like. Now, building on many of the aspects it discussed in those videos, most notably the ‘Heart of Joy’ centralised control unit, BMW has publicly unveiled what it is calling its new high-performance test vehicle - or the Vision Driving Experience as it is catchily known. 

Much about the monster prototype is already familiar: the firm has previously acknowledged that it has been developing a four-motor setup for years, and fully integrating the drivetrain, brakes, charging, recuperation and steering sub-functions has been a key component of making its colossal output not just manageable, but appropriately enjoyable. It is considered so crucial to the Neue Klasse generally that Oliver Zipse, BMW’s chairman, took to the IAA show stage in 2023 holding its black box aloft in triumph. So while the Vision car is definitely a ‘rolling test rig’ not meant for series production, the Heart of Joy inside it absolutely is - and therefore worth shouting about. Again. 

“The Heart of Joy enables us to take driving pleasure not just to the next level, but another one beyond that,” says Frank Weber, BMW’s development boss. “In addition, we are further increasing efficiency, and therefore boosting range, as in future the driver will brake almost exclusively using energy regeneration. This is Efficient Dynamics squared.”

In order that we all get the message (and possibly to sex it up a bit), the Vision Driving Experience is almost absurdly trick. Not only does it develop up to 13,269 lb ft of torque (!) and get colour-coded LEDs, it is also said to feature five very noisy ‘impellers’ - or electric fans as we’d know them - underneath to sucker the carbon chassis to the ground. Needless to say, BMW isn’t actually planning to generate 1,000kg of drag-free downforce or install maritime-grade torque in any resulting Neue Klasse model, instead it claims that by making the test rig cope with extremes of linear and lateral performance, ‘it will be able to handle the demands of everyday driving with ease’. 

Make of that what you will, but certainly BMW is deadly serious about a) the level of speed and precision it has achieved in unifying all dynamic functions, and b) the cutting-edge nature of the BMW Dynamic Performance Control software that runs the integrated system - not least because it has done all the coding in-house and reckons that it encapsulates more than a century of experience. The Heart of Joy is one of four ‘new super-brains’ that will power the Neue Klasse (each effectively a single computer that combines myriad elements that previously ran separately); the others will run everything else, including automated driving. 

BMW claims a world-first in combining drivetrain and dynamic functions (it has several patent applications pending) but the wider point is that by centrally marshalling the actuators responsible for acceleration and braking, vehicle stabilisation, dynamic steering functions and charging management, it can respond with ‘minimal delay’ - and by reducing latencies to the ‘millisecond range’ it can fully exploit the potential of electric drive systems in a way that wouldn’t be possible with traditional electric architectures or individual control algorithms. 

As well as delivering a more harmonious driving experience, BMW reckons it will also do a much better job of using the available energy more sparingly. It is no secret that modern EVs already achieve much of their braking via recuperation, but in the Neue Klasse the firm says that 98 per cent of drivers will not need to call upon the conventional brakes when stopping. Only under very heavy braking will the discs be required, an innovation that contributes to the 25 per cent increase in efficiency achieved across the board by the new consolidated system. 

Also, it explains the colour coding. The Vision Driving Experience car lights up its wheels in real-time based on what it’s doing: green is for acceleration, blue is energy recuperation and orange shows when the friction brakes are being used. Possibly not the most exciting or serious aspect of an EV purpose-built to go around corners (and into and out of them) at genuinely unnerving speeds, but who could blame BMW for going mad with this particular Christmas tree? Joy, after all, is what it’s apparently all about.

Oh man, I know I’m suffering from some mystery virus that has knocked me out. Just when I thought I was recovering I read this article.

Then….

I saw the first comment was pro-EV

and…

It was from Lee.

I genuinely checked the date to see if I’d lost a few days and it was April 1st.

I’m going to get some rest as I’m not ready to return to the outside world.

Looks amazing! Interesting tech too, 4 motors - I’ll be interested to see how stable it is.

I'm assuming that's the figure at the wheels/contact patch so not all that impressive really, it won't be generating 10x the typical motor torque for an EV, battery chemistry alone wouldn't permit that kind of output.

BMW showing off their EV prowess that would fit in perfectly with Blackpool illuminations. Drive it through the golden mile then dump it on the beach and wait for the tide to come in. When it's fizzed, banged and it's dead go and see septic peg the fortune teller to see what BMW could possibly do next then walk down the front with a tinny to buy your fish and chip supper.

Just quoting it again so I know it’s real wink

13,000 torques must be the reason it’ll do nearly all the braking with regen.
That’s very clever and could be a real step forward in particulate emissions.
They can keep the spinning wheel leds thanks.

All well and good, but it’s starting to look a bit 2024.

Is the world starting to move in a different direction that’s a bit more PHEV?

Genuine question…

The silhouette looks quite good, albeit about 10-15cm too tall. Front is a clever take on the kidneys, and is so much better than the current 5/7 series interpretation. Oh, but the interior... no. Physical HVAC buttons or nothing I'm afraid.

Sounds like you watched Harry Metcalfe’s video last night too.
EV = small cars, PHEV = mid/large cars if manufacturers still want to make a living.

At first I winced a bit, but on reflection it's not really much worse than all the rest of the cringeworthy marketing terms every firm uses.

Remains to be seen how appealing the production car with all this tech in it actually is. I'm assuming BMW sell more each year and the assumption is they know their customers... but it's also said that to assume makes an ass out of u and me.

When this concept car turns into a production car, will the enthusiast community have come around to high performance electric cars, or will the revolt against ever faster tech-fests be even stronger?

We've seen signs that not all is well in the fast car world with the way firms are going, the 4cyl C63 selling very poorly and Porsche delaying the move to full electrification. Who's going to be the first company to really blunder and put a lot of money into something that just doesn't sell at all?

Maybe in some markets, but UK and Europe? I can't see it. Too far gone with legislation now. PHEV is on borrowed time for anything but the most economical and functional options as soon as Euro 7 kicks in on 1st July. It's too late surely to change the regs with that much notice when manufacturers will have spent years developing products for the market requirements.

Agreed, that’s some fudgery with gearbox and final drive multiplication. Musk claimed some similar BS with one of his Teslas years ago
