Formula One ( F1 )

With regards to McLaren seemingly suffering a lack of power. They have the same engine as the Mercedes but are usually at the opposite end of the speed trap rankings. Most likely because Mercedes rely more on mechanical grip (hence the troubles with making the tyres last) so can sacrifice a bit of aero for speed. But all of the engines are so close (not sure about the Cosworth) that it makes little to no difference in terms of speed and reliability.

It's the whole package that determines the top speed, but I wonder if engine suppliers have to provide the same spec to all their customers? I'd be surprised if McLaren didn't get the same as Mercedes. Mercedes also have their trick rear wing which helps top speed when the DRS is open.

3 of the 4 suppliers have teams all through the field whereas neither of Cosworth's two teams are competitive - although Toro Rosso (Ferrari) and Caterham (Renault) aren't exactly mixing it at the front.
