The 2006 Cadillac DTS is a re-worked model based on the outgoing DeVille platform. Still front-wheel-drive – the last one in Cadillac’s stable – the DTS is powered by one of two available Northstar 4.6-liter V8 engines. The standard engine offered in Luxury models produces more torque and 270 horsepower. The optional engine comes in the Performance Package and offers less torque but twenty more ponies. Either is mated to a standard four-speed automatic transmission.
