Porsche upgrades 911 GT3 RSR

Porsche has updated one of its three factory racing 911s, the GT3 RSR, for the new model year with a number of enhancements designed to ensure it continues a successful GT2 series run. In the 2009 model, the capacity of the six-cylinder boxer engine has been increased from 3.8 to 4.0-litres delivering around 450HP at 7,800 rpm and a maximum torque of 430 Nm at 7,250 rpm. Power is driven to the rear wheels through a sequential six-speed gearbox. Other mechanical changes include the weight-optimised brake system and the lighter wiring harness.

On the outside Porsche made significant changes to the bodywork to ensure the GT3 RSR is more aerodynamic and has more even downforce front and rear. The changes include new air outlet slots to allow for an optional air-conditioning system and more adjustment on the rear wing to modify the handling for the conditions. Also improved is a “weight optimised” brake system and the installation of lighter wiring harness compared to the previous model.

Inside the racing cockpit is a new display that tells drivers when the best time is to change gears. Although Porsche did not go in to specifics about this, it looks similar to the system used in the Ferrari F430 and 599GTB supercars. As you can see from this gallery picture, the interior is completely stripped bare compared to a standard 911 and comes with the usual assortment of race-specific buttons.

Pagani unveiled Pagani Zonda R

Pagani had officially unveiled the Zonda R which is the ultimate racing Pagani that owners can drive on the road too. While it may not look it at first glance, the Zonda R shares only about 10% of its components with the Zonda F. The engine that powered the Zonda R is a Mercedes Benz AMG engine. It's the 6.0-litre V12 powerplant found in the racing CLK GTR that has successfully competed in GT championships. It's angled at 60 degrees, light in weight and produces humongous figures of 750hp (552kW) and 710Nm of torque. The gearbox is a 6-speed sequential model that sends power to slick tyres. Lubrication is a dry sump with a separate oil tank.

Further differentiating itself from other Paganis, the Zonda R has had its wheelbase increased by 47mm, overall length is up by 394mm while the track increased by 50mm. Bodywork was optimised to increase downforce even at low speeds, while an aerodynamic package of a bonnet with flaps, adjustable rear wing, and rear diffuser give the car exceptional cornering ability. While the car corners the driver is sitting comfortably inside a cabin that hugs and gives him a sense of stability and safety.
