Close-Up look at the 4WD DUT12 Formula Student racer [VIDEO]

The DUT12 is the second electric car of the DUT Racing team. The DUT 12 has four-wheel-drive system introduced this year. This makes it possible to use the brake energy from all wheels to recharge the battery which results in an even higher efficiency.

In the DUT12 the batteries are no longer placed behind the driver, but on both sides alongside the driver for better handling. Also a new method is used to produce the monocoque, namely prepregs. This method ensures that the resin is properly distributed between the fibres which will save weight with respect to last year.
