General Motors BEV 2 Vehicle Platform
The BEV 2 (or BEV II) vehicle architecture is a General Motors platform designed to underpin electric vehicles. The platform was engineered from the ground up to underpin electric cars.
Short for Battery Electric Vehicle 2, BEV 2 made its debut with the 2017 Chevrolet Bolt EV. Other vehicles on the platform are rumored to follow.
It is believed that BEV II was designed to support electric vehicles of all shapes and sizes, from subcompacts like the Bolt EV to compacts, midsize, and full-size cars. The flexible approach is known as a “skateboard” design in engineering circles.
Notable components of the platform include:
- Electric motor mounted in the front of the vehicle, under the “hood” of a conventional car
- Battery placed under the floor of the vehicle
- MacPherson strut suspension in the front and torsion-beam arrangement at the rear, though the latter could potentially be changed for other vehicle types
- Front-wheel-drive configuration, though all-wheel-drive and rear-wheel-drive is theoretically possible
- Flexible wheelbase configurations
- Extensive use of high-strength steels
|Type:||unibody welded steel|
|Size:||subcompact, compact, midsize, full-size|
|Supported vehicle type:||car, crossover|
|Drive wheels:||FWD (AWD and RWD potentially possible)|
|Layout:||front-mounted electric motor, battery under floor|
|Predecessor:||Gamma II (in Chevrolet Spark EV)|
In developing the Chevrolet Bolt EV, General Motors initially took to modifying the Gamma II platform that underpins the Chevrolet Spark, Sonic, Trax, along with the Buick Encore. As development progressed, however, engineers ended up developing an all-new platform that has become BEV II.
Asked if it shares anything with the Gamma platform that underpins the Chevy Sonic, Bolt chief engineer Josh Tavel stated: “The liquid sound deadener.”
Currently, the only powertrain in the BEV 2 platform is the 60 kWh lithium-ion battery/rechargeable energy storage system and an electric drive unit that makes 200 horsepower (150 kW) and 266 pound-feet of torque (360 N-m).
