This car is also good to the rubber, but bad for your fueleconomy. 8 laps/stint due to fuelconsumption means you can probably add some downforce (55/77) without any problems. About as fast as the Bentley, but not as fun! 3´26.509 is pretty OK.

+ Very well balanced, easy to drive, kind to the tyres.
