Motor Authority have published their review of the 2008 Cadillac STS 3.6L V6 sedan. ' Since the STS is a large sedan, its main competitors are the 5-series, E-Class or GS models. The Caddy offers three options in terms of engines - a V6, a V8 and a supercharged V8. Perhaps the most significant update from the 2007 model is the extra 47hp (35kW) to be found under the hood in the V6 model, which brings the 3.6L unit’s output to 302hp (225kW) and 369Nm (272lb-ft) of torque. The 4.6L Northstar V8, meanwhile, has not been updated and still musters 320 ponies (239kW) at a premium of $9,000 - though you do get extra equipment as well.
