Here’s a quick overview of the sweeping changes coming to Formula 1 racing next year. The biggest of these is the change in engine format from a 2.4 liter naturally aspirated V8 to a 1.6 liter turbocharged V6. We’re going to do a more in-depth look at the hybrid energy recovery system later, but basically there’s a lot more electric energy storage and there’s an electric motor built into the turbocharger that can either assist with boost or generate electric power to recharge the batteries. The KERS electric motor attached the crankshaft also carries over. There are also going to be major changes with the nose and front wing as well as the elimination of the exhaust blown rear diffuser.
