Next year outside of crumbly tires you will have a fuel mileage war. The driver will have a maximum one 100 kilos of fuel in his car at the start of the race, rather than 150kg today so the engineers need to find a 30% improvement in efficiency compared to today’s engines, while maintaining the same power output. The 2014 engines will use Direct Injection, pressurised to 500bar. It will make F1 a thinking driver’s formula, perhaps? One of the key areas of development is the energy recovery systems (ERS) and we were given an insight into these. Rather than the single KERS system used today, which gives around 80hp boost for 7 seconds per laps, the 2014 units will also harvest energy from an electric machine connected to the turbo and a heat converter, all of which will boost the output to 161hp for 33 seconds per lap. The unit can store 10 times more energy than the current KERS units and harvest 5 times more energy at the rear axle. Current thermal efficiency is 30%, the target is 4
