2011 Cadillac CTS-V Racing Coupe Revealed


Cadillac will be unveiling its new CTS-V Coupe race car – which is set to take part in the Sports Car Club of America World Challenge GT racing series this season – in Detroit at the 2010 North American International Auto Show next Monday.

The CTS-V Coupe will have to undergo plenty of modifications to meet up to the SCCA standards, but Cadillac has yet to announce what the changes for the future race car will include. Of course, the fact that the standard coupe gets a 556 HP V8 engine is reason enough for some teams to be shaking in their performance tires.

The sports car got some decent changes to its setup, like a carbon fiber body work, a ventilated hood, an aggressive diffuser, and a massive rear wing.

Press Release

CTS-V Coupe Race Car Photography


Cadillac announced today it will return to racing in 2011 with a race-prepared version of its CTS-V Coupe competing in the Sports Car Club of America World Challenge, North America’s top production-based racecar series.

The move returns Cadillac to a series where it competed from 2004 to 2007. Competing in the GT Class with the CTS-V Sport Sedan, Cadillac captured the Manufacturer’s Championship in 2005 and 2007 and the Driver’s Championship in 2005.

Cadillac will field two teams in the upcoming SCCA World Challenge GT Class with a racecar based on the CTS-V Coupe. The CTS-V line, which also includes the CTS-V Sedan and CTS-V Wagon, was recently named to Car and Driver magazine’s 10 Best list for 2011.

“Returning to racing in the SCCA World Challenge is a great way to demonstrate the performance and capability of the CTS-V Coupe,” said Don Butler, vice president for Cadillac marketing. “The racecars in this series are production based, which allows us to validate our performance against the best of our competitors on the track, and not just the showroom.”

Cadillac is working with Pratt & Miller, a New Hudson, Mich., engineering firm which specializes in motorsports, to develop the CTS-V Coupe racecar. While some of the production CTS-V components will be modified due to the unique demands of racing or to meet the SCCA series’ technical rules, every effort is taken to maintain as much production content as possible.

“The SCCA World Challenge lends itself well to a natural transfer of knowledge,” said Jim Campbell, GM vice president for Performance Vehicles and Motorsports. “The series will become a key test-bed for Cadillac. We anticipate using what we learn on the racetrack to ensure the V-Series stays on the cutting-edge of performance.”

The first event in the SCCA World Challenge is March 25-27 in St. Petersburg, Fla. Johnny O’Connell, a three-time GT1 champion in the America Le Mans Series, and Andy Pilgrim, who won the 2005 SCCA World Challenge GT class in a Cadillac, will be behind the wheel of the CTS-V racecars.

Introduced for the 2003 model year, the CTS-V has quickly earned a reputation among luxury sports car buyers. For the 2011 model year, Cadillac added the CTS-V Coupe and the CTS-V Sport Wagon to the CTS-V Sport Sedan, creating an impressive family of performance vehicles. The CTS-Vs feature Brembo brakes, a supercharged 6.2L V8 delivering 556 horsepower and a Magnetic Ride Control suspension system that can read and react to the road 1,000 times a second.

Started in 1944, the SCCA organizes and supports racing at all levels from amateur to professional. The World Challenge series is designed to provide teams, manufacturers and aftermarket suppliers a competitive production-based race series in which to prove their products. The races follow a 50-minute maximum time limit, with the number of laps and total distance determined by track configuration, lap times and race conditions.

2011 Porsche 911 GT3 RSR


Porsche has unveiled the 2011 911 GT3 RSR,which will debut on Dec. 11 at the Porsche R&D center in Weissach, Germany.

The new 2011 Porsche 911 GT3 RSR comes with a 4.0-litre, 6-cylinder boxer engine that now develops 455 hp (355 kW) at 7,800 rpm and 450 Nm of torque. The maximum rev range of the 2011 Porsche 911 GT3 RSR continues to be 9,400 rpm.

The transmission is a six-speed manual with sequential jaw-type shifting, a single-mass flywheel, hydraulic disengagement lever, a three-plate carbon-fiber clutch and a limited slip differential. The body consists mostly of steel but thanks to a series of weight saving modifications, the whole car tips the scales at just 2,689 pounds.

The 911 GT3 RSR also includes aero modifications, including a new front lip to increase downforce. The German automaker increased the size of the front wheels from 11 inches to 12 inches for better grip and less understeer.

The 911 GT3 RSR joins the 911 GT3 R and the 911 GT3 Cup at the very top of Porsche Motorsport’s lineup and costs a mere EUR 410,000 plus country-specific value added tax. If you already own a GT3 RSR and want the extra power and aerodynamic mods, but don’t want to spend almost half a million euros on a new car, the modifications are available as a kit for GT3 RSR cars from the 2010 season.

Debut for the 2011 version of the world's most successful GT race car



Stuttgart. The Porsche 911 GT3 RSR takes off into the new motorsport season with extensive modifications. The 2011 version of the world's most successful GT race car celebrated its international premiere at the "Night of Champions" party held at the R&D Centre in Weissach to mark the end of the motorsport season. Priority in the further development of the GT3 RSR was given to the newly designed aerodynamics at the front and rear, changes to the suspension kinematics and to the engine.

The 4.0-litre, six-cylinder boxer engine now delivers 455 hp (355 kW) at 7,800 revs, five horsepower more than its predecessor. The power increase results from an engine management system which adapts even better to different fuel grades, as well as a redesigned exhaust system and a modified air intake housing. Moreover, the driveability of the famously efficient engine has undergone further improvements. Maximum revs remain unchanged at 9,400 rpm.

Clearly visible are the modifications to the front. A new front lip provides higher downforce at the front axle. The front wheels are now wider with the rims growing from 11 to 12 inches giving additional grip and less of an understeering tendency. The position of the rear wing and the shape of the wing mounting also underwent optimisation and were adapted to the new rear fairing with additional air outlet louvers. The rear lid was also redesigned for optimised air ducting. Like the 911 GT3 Cup and the GT3 R, the RSR has now been equipped with the LED rear lights taken from the latest 911 road-legal cars.

The 911 GT3 RSR joins the 911 GT3 R and the 911 GT3 Cup as the top model of Porsche Motorsport's product range. The successful long distance racer from Weissach can be ordered now at a price of 410,000 Euro plus country-specific value added tax. All 2011 modifications are available as a kit for GT3 RSR cars from the 2010 season.
