The original Neue Klasse of the 1960s transformed BMW’s fortunes and set it on course to become the manufacturer it is today. As the 21st-century Neue Klasse enters its final stages of development, it's increasingly clear BMW has resurrected the name not to evoke nostalgia, but to reflect a deeper shift in philosophy. More than just a bold new styling direction, the Neue Klasse marks a major step forward in BMW’s technological strategy.

Underlining its ambition, BMW has revealed the Vision Dynamics Experience prototype, or VDX for short. Whilst it carries the essential architecture of the forthcoming Neue Klasse saloon – anticipated to be the EV equivalent of the 3 Series – the power and engineering go way beyond the scope of any production car. Capable of generating a mind-warping 13,269lb-ft (18,000Nm) of torque, the VDX is a one-off test rig designed to push BMW’s heavily touted “Heart of Joy” central ECU to its limits.

The theory goes that if the Heart of Joy can survive the stress test of processing so much power, the demands of everyday driving will be a doddle.

In order to transmit such a colossal output to the test track, the VDX features a series of special modifications. First up is a ground-effect fan system made up of five impellers that generate 1,200kg of downforce – even when static. Another 600kg is generated via the modified aerodynamics, while the prototype is equipped with massive 21-inch alloys, clad in 325×30 Michelin Pilot Sport Cup 2R rubber. All this means the VDX is capable of sustaining lateral acceleration in excess of 3G.

An Incognito Electric M3?

The camouflage is doing a good job of disguising the aerodynamic enhancements. But look a little closer, and the clues begin to reveal themselves. A jutting front splitter is the first giveaway, alongside huge intakes feeding a large radiator – a feature not usually found on a battery-electric vehicle.

Further tweaks include muscular flared arches, custom wing mirrors (in place of cameras), fat sills and a new bonnet with side cutaways and a vent in front of the windscreen. At the rear, there’s a significant diffuser, while the rear lights have also been extended to create a smart ducktail spoiler. It’s hard not to assume the VDX’s styling is heavily linked to that of the forthcoming electric M3.

BMW’s teaser videos have given away some styling nuances of the production car as well. The front door handles have been incorporated into the B-pillar, while the rear have been tucked into the Hofmeister kink. It also appears the doors will be frameless – something usually reserved for BMW’s coupés. One other detail is the embossed roundel in the bonnet and bootlid, as opposed to traditional badging.

The mix of prototype and production car continues on the inside, with an extensive roll cage separating four Recaro racing bucket seats, all equipped with Schroth Racing harnesses. We already know the Neue Klasse will be manufactured from a cocktail of aluminium, steel and carbon-fibre-reinforced plastic, the latter being on extensive display – especially in the rear, where it cradles the individual seats. We can only speculate if this forms part of a multi-compound "carbon cage" – already in use in the iX and first pioneered by the i3 – or whether it's unique to the demands of the VDX’s power output.

One element certain not to make it to the showroom is the central panel, which houses controls for the fan system (which auto-deploys when the driver selects Sport mode), electronically adjustable ride height, and power level. While the 13,269lb-ft of torque might grab all the headlines, the power level is programmable, with publicity demonstration drives occurring in the region of 1,300–1,700bhp.

The oval steering wheel of the Vision Neue Klasse concept, however, certainly appears to be making it into production, with its north-south spokes neatly recreating the kidney grille. Another production-ready element is the BMW Panoramic Vision screen and the 3D head-up display replacing conventional dials.

Command and Control

So, what exactly is the “Heart of Joy”? Essentially, it's an onboard “superbrain” that controls all the functions related to driving dynamics – throttle, braking, steering and energy recuperation. Approximately the size of a laptop computer, it will underpin all upcoming Neue Klasse electric models.

In all current production cars, these systems rely on separate electronic modules, each with their own algorithms and processing limits. The Heart of Joy consolidates these functions into a single, high-performance unit capable of processing data ten times faster than current systems, allowing for near-instantaneous adjustments to torque distribution, braking force and steering inputs.

One of the most significant advancements enabled by the Heart of Joy is the seamless integration of braking and energy recuperation. In conventional electric vehicles, the two systems function independently, with regenerative braking recovering energy under deceleration and friction brakes handling higher-intensity stops. BMW’s new approach merges these functions into a single, highly responsive system.

The company claims that 98 per cent of braking in normal driving can be handled through energy recuperation alone, significantly reducing wear on traditional brakes. Only in emergencies or under extreme braking will the system engage friction brakes. BMW also claims this not only increases the car’s efficiency by up to 25 per cent but also provides a smoother, more consistent braking feel for the driver.

The benefits extend to handling and cornering. Because the Heart of Joy processes inputs more rapidly than current systems, it can dynamically adjust torque distribution and braking force in real time. This results in more stable, predictable car behaviour, reducing the need for constant steering corrections and allowing for precise, repeatable cornering across all surfaces and in all weather.

BMW engineers also highlight improvements in low-speed driving, where rapid signal processing enhances control in stop-start traffic and parking manoeuvres.

Another quirk of the prototype is the LED-embedded alloy wheel covers, which change colour depending on what the Heart of Joy is up to: acceleration is indicated in green, energy recuperation in blue, and conventional braking using the friction brakes in orange.

Bavarian Microchips Works

The Heart of Joy is one of four new high-performance computing units set to define the Neue Klasse platform. While this headline control unit focuses on driving dynamics, three additional processors will manage automated and highly automated driving functions, infotainment, and core vehicle operations such as climate control and lighting.

All have been developed in-house by BMW engineers. Each one cuts latency, reduces weight, and enables over-the-air software updates that can refine performance over time.

Over 75,000 man-hours have been invested into the Vision Dynamics Experience prototype over a 12-month period. While it's extremely unlikely all of the VDX’s power and technology will make it to BMW showrooms, the Heart of Joy promises the Neue Klasse series production cars will be both more fun to drive and more efficient – thus ensuring its “Ultimate Driving Machine” tagline is future-proofed.
