New 2007 Porsche RS Spyder Debuts In Paris Too
Peugeot was not the only factory showing off its 2007 sportscar challenger today (Thursday 28 September).

A new for 2007, evolution version, of the Porsche RS Spyder was unveiled in Paris too, marking clear intent that the Porsche factory is still very much intending the LMP2 car to find customers on both sides of the Atlantic.

To truly see all of the differences between the current cars run by Penske and the new car you’d need to examine the two side by side, but the overall effect is of a sleeker, less fussy package.

Porsche’s intention is to “limit the cost of racing the car with a view to future entry of the RS Spyder by customers”.

The company suggests that it has “enhanced the aerodynamic efficiency of the car, but also improved the range of set-up options for different kinds of racetracks”.

The carbon-fibre body has been “modified for an even higher standard of ease and convenience for service and maintenance”.

The 3.4 liter, 90 degree V8 in the revised car will produce a claimed 503 bhp, an increase of 23 bhp. The complete car will weight “exactly 775 kg”.

Porsche has “upgraded the gearbox with the primary objective to make the gearshift even more reliable, smoother and less demanding on all the components involved, and at the same time even more precise”.

Romain Dumas, racing the 2006 car at Road Atlanta this week, is hoping that “the new car will be quicker than this one. The target will be to go quicker and to be closer to the LMP1s.”

He’s aware of LMP2 competition hotting up in 2007.

So a faster, developed version of the 2006 RS Spyder - and a more customer-friendly car too.
