The Cadillac V-Series is a line of high-performance vehicles tuned by the General Motors Performance Division for the Cadillac division of General Motors. Models in the V-Series include the CTS-V coupe, sedan and wagon. Cadillac reportedly has no plans to create V-Series versions of its SUVs, the Escalade and SRX. Most V-Series Cadillacs feature high-performance V8 engines mated to manual six-speed transmissions or automatic transmissions in the STS-V, XLR-V XTS-V and 2009+CTS-V, top-of-the-line Brembo brakes and revised suspension systems, revised interiors and special V-Series bodywork which is intended to improve vehicle performance as well as differentiate them from their normal production counterparts. Cadillac has also re-entered Motorsport competition with their 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. In addition to the Corvette and Camaro, the V designation draws comparisons to other high-performance models by GM such as the Super Sport series, Chrysler's SRT, and Ford SVT line of high-performance vehicles. 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 V8 engine that was borrowed from Corvette. The engine was renamed as "LSA" and it produces 556 horsepower as well of torque. The same "LSA" engine is used in CTS-V coupe and wagon. The CTS-V is the only V-Series by Cadillac for the 2014 model lineup, and it was originally created to compete with BMW M3 sedan and coupe, as well the M5. Future plans for the V-Series include a new ATS-V sedan 〔(ATS-V sedan )〕 and coupe 〔(coupe )〕 along with a third-generation CTS-V sedan.〔(3rd generation CTS-V sedan )〕 ==First-generation V-Series== The first V-Series model of the Cadillac family was the CTS, which was built on GM Sigma Platform like the core model. Since a V8 engine was used, it required a unique engine cradle distinct from the base CTS V6. Larger anti-roll bars and larger shocks were also added. The spring rate was significantly increased. Right at front above the ground, GM LS engine V8 from the C5-generation Corvette Z06 was fitted and coupled—also from the C5 Z06—with a six-speed Tremec manual transmission. XLR hard-top was the second Cadillac to join the V-Series. It was an ultra-luxury segment car, first introduced in 2005 and it shared platform with Corvette C6. The XLR-V used a supercharged Northstar V8. For the XLR-V, the engine was certified by the SAE to produce 443 hp (330 kW) and 414 lb·ft (561 N·m). The supercharger and four intercoolers were built into the intake manifold. A six-speed automatic transmission, larger brakes from the Z51 Corvette, and 19-inch wheels were used. The XLR base price was $98,000 and by 2008 it reached $101,300 making it one of General Motors' most expensive vehicles of all time. A year after XLR-V launch and two after CTS-V, in 2006, Cadillac started producing STS-V sedan that also featured the famous Northstar V8 engine from XLR-V. However, the supercharged Northstar V8 in STS-V had 26 more horsepower and 25 more lb-ft of torque than XLR-V's. The engine was mated to a driver-adjustable transmission with two shifting modes, larger brakes by Brembo, larger ten-spoke alloy wheels (18 in × 8.5" front, 19 in × 9.5" rear), Pirelli run-flat tires, a faster steering ratio, and a stiffer suspension than the standard STS. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cadillac V-Series」の詳細全文を読む スポンサード リンク
