Although the 2014 engines are actually smaller, next year’s cars will have to fit in a much larger energy recovery system and engineers will have to package a significantly larger cooling area into the system to cool the KERS unit and the air that comes from the turbocharger before it enters the engine.
To compensate for this increased weight, the minimum weight of the cars has been increased from 642kg to 690kg.
Because of the extra weight, teams will be doing all they can to keep the extra weight down and shift ballast to the areas that need it at certain circuits. This spells bad news for heavier drivers such as Nico Hulkenberg, whose chances of securing a top drive could be hindered for this very reason.
It’s a regulation change that was slammed as “disgraceful” by former world champion Nigel Mansell on BBC Sport.
It's wrong. They [the drivers] are not jockeys. It's disgraceful, it's discrimination against the medium-sized large driver. In years gone by, we didn't have traction control or power steering - you had to be a strong driver and there were a lot of strong drivers. If you had this weight limit, they wouldn't have been able to drive cars many years ago - or they would have driven with great difficulty. So I think get the weight limit up a bit, make some cars carry some ballast so that the bigger drivers don't suffer as much.
