Cadillac V series

The Cadillac V series (stylized as V-Series) is a line of high-performance vehicles tuned by the General Motors Performance division for the Cadillac division of General Motors.

Introduced in 2003, the V-Series, along with its new 'Art & Science' design language, marked a concerted effort at Cadillac to initiate a brand resurgence, to address their high-performance competition and to attract a younger demographic. The first model was the 2004 Cadillac CTS-V, which itself became a successful seller and steered Cadillac in the new direction for the following decade.

Cadillac also participates in motorsport using the V series name. Their first V series race car was the CTS-V.R, a joint venture between GM Performance Division and Pratt & Miller race team, most famous for their role in GM's Le Mans-winning Corvette C5.R program. Three race cars have carried the V series name since then, most recently with the Cadillac V-Series.R sports prototype.

In 2009, the second-generation CTS-V sedan achieved a lap time of 7:59.32 at the Nürburgring Nordschleife, which was the fastest documented time for a production sedan on factory tires—until the Porsche Panamera Turbo clocked a time of 7:56 in July 2009—thanks to a heavily tuned "LS9" EATON-supercharged 6.2-liter (380 in³) V8 engine that was borrowed from Corvette. The engine was renamed as "LSA" and it produces 556 horsepower and 551 pound-feet (747 N⋅m) of torque. The same "LSA" engine is used in the CTS-V coupe and wagon.
