Electric car sets world acceleration record

Thanks to Phil Krause for suggesting this post .

An electric racing car built by Swiss student engineers has broken the world record for acceleration by battery-powered vehicles. The grimsel car took only 1.513 seconds to reach 100kph (62mph) – slashing about a quarter of a second off the previous record time.

So far, no petrol-powered production car has managed to hit the same speed in a comparable time. The grimsel needed only 30m (98ft) of track to reach the landmark speed. The previous record of 0-100kph in 1.779 seconds was set by a team from the University of Stuttgart last year. By comparison, the fastest production vehicle, the Porsche 918 Spyder hybrid, takes 2.2 seconds to reach the same speed.

The car has been built and refined over the last year by 30 students studying at ETH Zurich (ETZ) and Lucerne’s University of Applied Sciences and Arts. Almost all of car’s parts have been custom built apart from its tyres, battery cells and the motor control units. In a statement, ETZ said the four-wheel drive system used by the grimsel was key to its swift acceleration. A powerful motor is mounted on each wheel and the car has a sophisticated traction control system that adjusts the performance of each one to maximise torque. Edited from: Electric car sets world acceleration record

    How many years until they are competing at Silverstone? Five? Ten?

    They already have formula E racing which started in 2012 which are totally electric racing cars. It’s ok but in a race that lasts 50 minutes they have to swap cars half way through because the batteries run out. They can go 0-60mph in about 3 seconds which is about the same as a typical supercar or cheater. Purely battery power needs to improve dramatically but we are going in the right direction. Compare this to formula 1 which lasts 2 hours without refuelling and which are much faster. They can typically do 0-60mph in about 2.5 seconds. However, in the past when engines were bigger they could do it in about 1.6 seconds. The current formula 1 cars have an electric element built into the engines which adds 160bhp which retrieve heat energy from the brakes and exhaust. These only have a 1.6 litre engine but can go faster than the 2.4 litre cars they replaced and are about 35% more efficient. We need all these races to push technology faster than it naturally goes.
