Being that the STS targets a slightly older buyer than the smaller CTS, its design is a tad on the conservative side. The headlamps are still vertically stacked, to tie it in with the new family face, featuring a dual-beam xenon technology which allows the lights to "bend" around curves for safeties sake. There will be no mistaking the updated model's chrome grille, being a modernized version of the substantially sized dual-slat design. Similarities can be seen from side-view and when looking from behind as well, but comparatively it is a distinctive design.

Under the skin, however, there isn't a great deal that differentiates the two. Each model rides on GM's proven Sigma chassis architecture, a rigid performance-oriented design. Obviously Cadillac has lengthened and widened it somewhat, with the STS measuring 4,980 mm (196.1 in) long, 1,850 mm (72.83 in) wide, and 1,460 mm (57.48 in) tall.

I always found it a bit of a miracle that the outgoing Seville STS drives as well as it does, being that it is front-wheel drive and powered by a high-output V8. Such engineering marvels are no longer necessary as the STS will feature rear-wheel and optional all-wheel drive. Base power will be provided by a 3.6-liter V6, the first time a 6-cylinder engine has been used in Cadillac's midsize car since the unpopular downsized 1986 through 1991 iteration was replaced. The new engine is a sophisticated piece of hardware, producing 255 horsepower and 252 lb-ft of torque. With an estimated sub-seven second 0 to 100 km/h sprint few will find it necessary to upgrade to the Northstar 4.6-liter V8 - that is if they aren't persuaded to drive it as well. The 32-valve, DOHC engine develops 320 horsepower and 317 lb-ft of torque, good enough to drop a full second off of the base car's acceleration time. Both cars feature a 5-speed ZF automatic with standard manual-mode.
