The STS is a luxury car sold by Cadillac. The STS name was previously an upscale trim level of the Cadillac Seville, but that name was retired for 2005.
2005
It is based on the GM Sigma platform, and replaces the Cadillac Seville. It is a rear wheel drive car, a departure from the previous model. It is the first Cadillac sedan to be available with all wheel drive. Engines are a 3.6 L High Feature LY7 V6 with 255 hp and 252 ft.lbf and the 4.6 L Northstar LH2 V8 which outputs 320 hp and 315 ft.lbf in the STS. Remote ignition is optional.
Wheelbase is 116.4 in, though overall length is shorter than the Seville. Interior space is greater than its predecessor, though. A heads-up display is optional, as is a 300 Watt Bose stereo system with MP3 capability. Base pricing starts at US$40,995, and extends to US$52,240 for the AWD V8 model.
STS-V
The 2006 V-series STS-V was introduced at the 2005 Detroit Auto Show. It features a 440 hp supercharged 4.4 L version of the Northstar V8, along with handling upgrades.
Cadillac gave the public its first glimpse of the STS-V in its Super Bowl commercial, which aired February 6, 2005. The STS-V will have a 0-60 mph acceleration time of under five seconds.
The STS-V has bigger brakes, larger wheels, faster steering and a stiffer suspension than the standard STS. It will go on sale in the United States in late 2005 for just under US$80,000.
