Dodge Viper SRT10 ACR-X

Dodge pulled the cover off the newest special-edition model of the 2010 Dodge Viper SRT10 lineup. The Dodge Viper SRT10 ACR-X is a turn-key, non-street legal race car that is slated to make its on-track debut in the summer of 2010.

"The Dodge Viper SRT10 ACR-X takes the performance attributes of Viper to an even higher level for a wide range of drivers starting with the grassroots racer all the way up to the professional," said Ralph Gilles, President and CEO, Dodge Brand. "This project is a result of many years of performance engineering expertise from our SRT team, combined with the passion and dedication of Viper Nation, to keep the Viper racing tradition going strong on tracks around the country and the world."

Combining the best performance attributes of the record-setting, street-legal Dodge Viper SRT10 ACR (American Club Racer) and the safety equipment of championship-winning Viper Competition Coupe, the Dodge Viper SRT10 ACR-X is powered by the SRT-developed 8.4-liter V10, equipped with factory headers and a low-restriction exhaust system, that produces 640 horsepower (40 more than production model).

The suspension also is tuned and upgraded specifically for on-track usage, while the weight is lightened by a full 160 pounds (versus the standard production Viper) to take on even the most challenging road course. Additional aerodynamic upgrades improve downforce, while enhancing stability and significantly improving grip in high-speed cornering.

Similar to the Dodge Viper Competition Coupe, the Viper ACR-X contains factory-installed safety equipment such as a factory-designed roll cage, fuel cell and race seat. Additional racing components are added to meet the significant durability and reliability requirements for on-track competition.

In what will be the final year of production for the current generation Viper, the ACR-X is the third limited, special-edition model to be introduced by Dodge. "We're going to make 2010 the most exciting year for Viper yet with specially developed cars for the street and the track," added Gilles. "The ACR-X is targeted at road-racing enthusiasts who want to successfully compete in our ultimate American sports car."

Last month, the SRT team used a testing session at Laguna Seca raceway to shake down the Dodge Viper SRT10 ACR-X for the first time. Behind the wheel was professional driver Kuno Wittmer from the SCCA Pro Racing SPEED World Challenge Touring Car Championship series, who was able to run consistent 1:31.00 lap times around the 2.238-mile, 11-turn course. Wittmer's lap times were more than 3 seconds faster than the street-legal Dodge Viper SRT10 ACR that holds the production car track record at Laguna Seca raceway. Read More!

Audi S5

Audi is refreshing the A5 model series. Advanced technologies are being added to the Sportback, Coupé, Cabriolet and S5 models in the areas of the engine, quattro drive and infotainment for even more efficiency, sportiness and intelligence. The updated design visually underscores the technical expertise involved in these versions.

The Audi A5 models are now more distinctive than ever. The rear lights and the headlights have been redesigned and are optionally available in xenon plus technology with homogenous LED daytime running lights. New colors and materials accentuate the interior, and many details of the operating concept have been fine-tuned.

Each of the four TDI diesel and three TFSI gasoline units in the new engine lineup include forced induction and direct fuel injection. The new 1.8 TFSI features a number of groundbreaking innovations. Fuel consumption has been reduced by 11 percent on average. The start-stop system and the recuperation system come standard with all engine-transmission configurations.

Each engine is matched with the ideal drivetrain - six-speed manual, multitronic, seven-speed S tronic, front-wheel drive or quattro drive. When combined with S tronic, the quattro drivetrain uses the crown-gear center differential and torque vectoring; the sport differential is the perfect complement. The chassis has been more finely tuned, with the optional Audi drive select system and dynamic steering making the Audi A5 even more fun to drive. The electromechanical power steering is new to the Audi A5 family.

The new A5 is a highly intelligent car. Its driver assistance systems have undergone intensive further development. The range of infotainment options now includes the Bluetooth online car phone, which delivers a number of special services and connects the Audi A5 to the Internet. Read More!
