The Venturi Buckeye Bullet 3.0 (VBB3) is an American record-breaking car with which professional racing driver Roger Schroer set a speed record for electric vehicles on the Bonneville Flats in September 2016 . It is considered to be the most powerful electric car ever built.

The VBB3 is an electric vehicle with four motors that together generate 2100 hp and should bring the car to a speed of up to 800 km / h. The main sponsor and engine supplier of the Ohio State University- based development team is the automobile manufacturer Venturi Automobiles . The vehicle is named after the Ohio horse chestnut .

The first thing that should be improved in 2013 was the record of 495 km / h set by Schroer in August 2010 for electric vehicles, and in doing so, if possible, surpassed the 400 mph (643 km / h) mark . The following year, Don Vesco set a speed record for wheel-driven land vehicles of 739 km / h with the Turbinator .

The 4-pole asynchronous machines work in a speed range from 0 to 10,500  min -1 and suck to a maximum of 12,000 min -1 . The motors draw their electrical energy from a total of 2000 lithium iron phosphate battery cells . A modified inverter is used to convert the DC voltage into an AC voltage of a useful level. The car has a tubular frame made of chrome-molybdenum steel ( “space frame” ), the rest is largely made of carbon fiber reinforced plastic . The total weight is more than 3000 kg. The eleven meter long body was optimized with computer models, but not in the wind tunnel .

After flooding in 2013 thwarted all attempts, the first tests on August 22, 2014 resulted in an average speed from two runs of 342.17 km / h. The FIA ​​recognized this as a new record in Category A Group VIII Class 8 for electric vehicles over 3.5 tons. Even in 2015, after a rainy summer, the track was not in optimal condition. Nevertheless, the vehicle reached an average speed of 386.75 km / h - a new record. Roger Schroer said that in eleven years he had never driven in such difficult conditions on the Bonneville Saltflats. The car lurched on the still damp salt, the bumps caused cracks in welds and a coolant tank in the front of the car broke. Nevertheless, the team was certain that they would be able to achieve the desired goal under good conditions.

It succeeded on September 19, 2016: With 549.4 km / h (average speed), Roger Schroer was able to clearly surpass his own record from 2010. The top speed was around 576 km / h.
