Ten lessons from F1's first test
Everything you need to know about this year’s crop of F1 cars from Jerez

The F1 teams are using a different language for the energy recovery systems this year, so we better get used to it. The KERS is now the MGU-K (Motor Generator Unit, Kinetic) and it drives through the MGU-H (for Heat) which is a clever little thing which converts the heat from the turbo and ‘compounds' it back in to the system, with the excess going into the battery along with the juice from the brakes.
Cars can harvest two megajoules a lap and can use four megajoules, ten times last year's limit. What's more, they have 33.3secs each lap in which to use the harvested energy, not the piddling 6.7secs they had before. Learning then how much to keep in reserve with a potential lap time benefit of two seconds is going to require the drivers to take a big dose of the smarts.
