badges were added on 2006 models. For performance enthusiasts, a high performance suspension package (RPO FG2) was available as a dealer installed option. Engine The CTS sedan is enhanced with GM performance parts like a GM LS engine V8 from the C5-generation Chevrolet Corvette Z06, as well as the Corvette Z06's six-speed Tremec manual transmission gear ratios. From 2004 and 2005, the CTS-V came with the 5.7 L pushrod OHV LS6 engine producing at 6,000 rpm and of torque at 4,800 rpm. The torque reduction of the CTS-V vs the LS6 used in the C5 Z06, was due to the exhaust manifold that needed to be used on the CTS-V. From 2006 to 2007, the previous LS6 engine was superseded by the new 6.0 L OHV LS2 engine as used in the base 2005 Chevrolet Corvette. The new LS2 engine was rated at the same at 6,000 rpm with the peak torque of at 4,400 rpm. While both engines offer the same HP and torque specifications, the LS2's benefit was a wider torque band, due to the higher displacement it offered. Transmission The only available transmission was the six-speed manual Tremec T56. The transmission used the skip-shift feature to conserve fuel during light loads by preventing drivers from using the second and third gears, and a dual mass flywheel to reduce "rattle" in no load conditions. The rear axle was a Getrag limited slip IRS unit with a 3.73:1 ratio. Performance General Motors states a 0- time of 4.6 seconds for the first generation CTS-V, with the quarter mile time estimated at 13.1 seconds at , onward to a stated top speed of . The 14 inch diameter Brembo brakes can slow the vehicle from in 110 feet. The first generation CTS-V also posted a lap time of 8 minutes 19 seconds at Germany's famed Nürburgring Nordschleife, competitive with rivals such as the Mercedes-Benz E55 AMG and BMW M5. Second generation (2008) GM revealed the all-new 2008 CTS at the North American International Auto Show in January 2007. The 2008–2009 base model featured a 3.6 L LY7 V6 with and of torque carried over from the previous generation. A second engine, a new 3.6 L direct-injection V6 VVT engine with and of torque was also offered. For 2010, the base engine changed to a 3.0L variable valve timing (VVT) V6 with and of torque. A 6-speed manual transmission was standard
