VW BUDD-e On Display At CES (InsideEVs/Tom Moloughney)
Volkswagen's intention to use a flat battery pack in sandwich floor style in long-range electric cars has attracted a lot of comments of late.
With the Volkswagen BUDD-e unveiled at 2016 CES, we got glimpses of VW's future with bold reference to Tesla's architecture.
Over time, we think that most BEVs will evolve towards this more optimal setup.
Volkswagen BUDD-e includes:
- large 101 kWh battery
- two electric motors with total of 235 kW of peak power
- high-power fast charging to 80% capacity in 30 minutes
VW BUDD-e First On New MEB Platform
Another similarity are two motors - one per axle. Power output isn't in Tesla range because this is a different vehicle class, but just look at the motor/single speed gearbox/power electronics. Pretty much the same concept with slightly different implementation. Of course, BUDD-e is then All-Wheel-Drive on demand, while at steady speed just one motor could work to save energy.
And the third is charging - no more 40-50 kW. Now 80% can be replenished in 30 minutes, that's 160 kW in theory starting at 0%, but most likely this is only an indication of 150 kW CharIN CCS fast charge initiative to be considered as the next step.
150 kW is comparable to Tesla's 120+ kW and now, unlike e-up! and e-Golf, even the Combo charging inlet is on the driver's side, just like in Tesla.

"MEB: The new architecture for Volkswagen’s electric vehicles
With BUDD-e, Volkswagen demonstrates what electric mobility could be like by the year 2019. Volkswagen’s new MEB platform will enable a series production car to have pure electric range that is on par with today’s gasoline-powered cars by the end of the decade. The time required to charge the batteries to 80 percent of capacity is anticipated to be reduced to about 30 minutes by then, marking an operational breakthrough for EVs.
BUDD-e is the first concept car developed by the Volkswagen Group that is underpinned by the new Modular Electric Toolkit (MEB). This architecture heralds a fundamental change in electric cars and ushers in a revolution in automotive technology, leaving today’s fossil-fuel powered internal combustion engines and drivetrains in the past. This significant innovation will lead to huge changes in the development of electric-powered Volkswagens in the years to come, from body and interior design, to packaging and drive characteristics.
The new platform is designed to have the space for electric drive components and large batteries while maintaining interior space and driving dynamics. MEB will allow for spacious interiors with the smallest possible footprint to enable easy and nimble transportation. In addition to their space, MEB vehicles will offer high levels of functionality and networking thanks to the new vehicle architecture, instrumentation, and operating systems. New and enhanced assistance systems will provide passengers with safer transport.
Dynamic performance is, and will remain, a key part of Volkswagen’s DNA, and MEB vehicles will be no exception. With a focus on optimal balance, future VW vehicles based off the platform will offer the kind of agility, strong acceleration and handling that VW customers have come to expect. New battery and electric drive componentry will enable inexpensive access to e-mobility: a much longer purely electric range will allow these vehicles to become the primary transportation in many consumers’ households.
The new MEB delivers a drivetrain architecture that is specifically tailored for the integration of compact electric motors and high-performance, highly-efficient batteries. The 101 kWh battery is flat, to save space, and integrated into almost the entire vehicle floor. It powers two electric motors, one to drive each axle.
The front and rear motors power all four wheels and enable a top speed of 93 mph. The total range of up to 373 miles** (estimate based on the New European Drive Cycle (NEDC), 233 miles estimate when based on EPA drive cycle) is achieved on a full charge, putting the BUDD-e on a level playing field with today’s gasoline-powered cars. Like today’s electric vehicles, the BUDDE-e offers several levels of plugged-in charging with the added benefit of cordless inductive charging.
Another benefit of the new MEB is entirely new packaging opportunities, highlighted throughout the BUDD-e concept. One significant enhancement is illustrated by the arrangement of the heating and air conditioning unit. For instance, the innovative new heating and air conditioning unit has been completely integrated in the front end of the car which allows for significantly more available space, improves air quality (thanks to larger and more robust filters), and results in a reduction of fan noise inside the cabin for excellent acoustics."
