So what are the big differences / ever changing of rules then?
Mainly centred around the aerodynamics, to reduce downforce primarily. There are other changes too though, to compensate for reduced aerodynamics, proper slick tyres are back in, cars are now narrower track (should be less draggy through the air), they have to have an “energy recovery system” fitted (think like the way when you brake in a Hybrid car such as a Prius energy “recovered” from braking is used to charge the battery) which then allows them a “boost button” which gives them a few more horsepower for a pre-determined number of times to promote overtaking moves.
Fingers crossed, all the changes SHOULD make for more overtaking and a more interesting race series, that said though, at what cost. It seems a very expensive way of going about doing something that could be acheived by much simpler rule changes, or even just capping the bloody budgets allowed by each team! Cap each team’s budget at £10m for the entire year say, and it’s going to be a much more effective leveller than most of the new rules are going to be, cos as it is the team with the biggest budget that allows them to get round the new rule changes most quickly, is likely to win. In other words, don’t expect anything other than a Ferrari/McLaren show all year long.
