Electric car broke 0-100 km/h world record

Team at Academic Motorsports Club Zurich (AMZ) broke the world acceleration record from 0 to 100 km/h (62 mph). The previous leader managed to achieve such a speed in 1.779 seconds. The electric AMZ's formula Grimsel was able to defeat it quite significantly. This small electric car was able to achieve 100 km/h in 1.513 seconds only and because of that, it is the fastest accelerating car in the world. It has defeated all the cars with combustion engines too. Grimsel drives at 100 km/h after 30 meters only.

 

 

Such values were achieved mainly because of very low weight of the vehicle. It weighs 168 kg (370 pounds) only. It has 4 electric engines for each wheel. Each engine produces 37 kW (50 HP) and weighs 3.4 kg only. The total power is 148 kW (200 HP). Even though the formula has a horsepower of a mid-size car or a small hot hatchback, it has enormous total torque of 1630 Nm (1202 ft-lb). Each wheel is independently controlled in order to maximize acceleration according to the actual drag of the wheel. These algorithms were tweaked during the tests on the airport.

The successful attempt for a new record was set at the military airport in Dübendorf. The result is an average of two attempts in opposite direction in order to eliminate the influence of the slope of the track and wind conditions.
