McLaren KERS in demand

While every other team muse the KERS dilemma, it is clear that McLaren Mercedes is the 2009 champion in the new energy recovery technology. Toyota, the Red Bull teams, Williams, Force India and Brawn have not fitted KERS to their cars at all this season, while Ferrari, BMW and Renault's experimentations have shown an unclear benefit from their respective systems.

The works cars of Lewis Hamilton and Heikki Kovalainen, however, have consistently used Mercedes-developed KERS at all four Grand Prix so far. Norbert Haug revealed to the German press on Tuesday that the marque's success with KERS in F1 has made its system popular.

"We have had several inquiries," said the Mercedes competition boss, "both from teams that want to enter in 2010 and teams that are already established." Mercedes has also expressed interest in being the sole KERS supplier, should the Formula One Teams' Association agree to adopt a standard unit solution for 2010 and beyond.
