PICS : What's all new in F1 2014

A driver will have to start from the pitlane if he uses more than five entire units while each additional element above the allocation will incur a 10 place grid penalty. The new power units make a different, softer noise to the screaming V8s, which were introduced in 2006, just as the V8s were distinct to the previous V10s and V12s. While the engines rev at 15,000rpm, the turbo will make its own distinct noise as it spins at 125,000rpm.
