Williams will run its own battery-powered KERS system in 2011, technical director Sam Michael has announced.

The Grove based outfit runs its own hybrid systems company, and developed an unique flywheel system that is now used by Porsche in GT racing.

But Sir Frank Williams revealed recently that the flywheel system is so big “it would make our (F1) car like a London double-decker”.

So in 2011, with KERS returning to formula one, Williams Hybrid Power is working on a more conventional electrical version.

“Everything is being done in-house,” Michael confirmed.  “Only the battery cells are being bought from outside.”

There were high hopes of a remarkable racing car on January 31^st when the Renault R30 was unveiled, with a front wing that resembles very much the 2009 version, even though Alonso had pinpointed that that was precisely one of the main problems of the 2009 car.

Nevertheless, next day the car that made its debut in the racetrack and the characteristics of the front wing of three stacked elements was totally different.  Specifically, it’s very similar to the one that McLaren has.

The changes made on the R30 are very deep and one has to pay much attention.  The rear wing is also new, with a drop in the middle where the sharp fin gives it the aerodynamic support.

The nose’s cone is absolutely different from the rest of the scuderias, contrary to the 2010 trend which is V shaped.  Even though it is still a bit bulky, it lacks the extra protuberance underneath, with the purpose of gaining more resistance.

The wings are a clear evolution and contrary to the other three cars previously launched by Renault, the R30 has huge sidepod air inlets that extend down to the vehicle’s floor.  Instead of rectangular air inlets (more conventional) they are bigger in the high part than in the low one.

There’s no doubt that the team is quite interested in the temperature, because over the engine’s cover are connected heat stickers.  The engine’s exhaust have been moved towards the back and more to the middle of the car.
