Porsche develó hoy el GT3 RSR, el vehiculo de carrera
basado en el Porsche 911 mas potente hasta el momento. Las
caracteristicas mas distingidas del nuevo GT3 RSR se pueden ver en las
mejoras de la parte frontal, perfeccionando la aerodinamia. Aunque la
mayoria de las innovaciones estan escondidas bajo el chasis, que fue
mejorado para reducirle el peso.
El GT3 RSR esta propulsado por un motor Boxer de 3.8
litros que genera 465 hp (342 kW) a las 8000 rpm y un torque máximo de
430 Nm a las 7250 rpm.
El precio del GT3 RSR es de 349,800 Euros mas impuestos.

The Porsche GT3 RSR launches into the new model year with extensive modifications. The most powerful race car based on the Porsche 911,
which last year scored wins at the 24 hour races of Le Mans and Spa as
well as overall victory at the Nuerburgring 24 hours, competes in the
GT2 class at international long distance races. The most distinguishing
feature of the new GT3 RSR is the front end which received major
improvements to the aerodynamics. The majority of innovations however
are hidden under the weight-optimised body.
Aside from the easily recognisable additional spoilers
on the front apron, so-called flicks, an optimised air ducting with
newly-designed side air outlets generates more downforce and reduces
drag. The rear end including the rear wing was taken over from the
predecessor. Extensive changes to the suspension cinematics increase
mechanical grip considerably. The range of possible suspension set-ups
The 3.8-litre boxer engine of the GT3 RSR remains
unchanged apart from slight improvements to details. It delivers 465 hp
(342 kW) at 8,000 revs per minute and delivers a maximum torque of 430
Nm at 7,250 revs. The rev limiter of the efficient six-cylinder kicks
in at 9,400 rpm.
Much of the know-how in the GT3 RSR’s totally new gearbox has come from
the RS Spyder sports prototype. The sequential six-speed unit,
developed by Porsche engineers, is considerably lighter than its
predecessor. Internal friction was substantially reduced. The flat
angle of the drive shafts allows teams a wider range of suspension
Aside from the GT3 Cup and the GT3 Cup S, the GT3 RSR
is the third race car based on the Porsche 911 offered by Porsche
Motorsport. Thirty-five units of the fastest and most powerful long
distance racer made in Weissach, apart from the exclusive RS Spyder
sports prototype, are now being produced and delivered to customer
teams around the globe. The price of the GT3 RSR is 349,800 Euro plus
