2008 Cadillac STS V-6 - Previews

When we first reported on Cadillac’s refreshed 2008 STS from the New York auto show, we quoted the new base engine—a 3.6-liter DOHC direct-injection V-6—at 298 horsepower and 268 pound-feet of torque. Since then, four more of each have been found, bringing the totals to 302 and 272, respectively.

That’s just 18 fewer ponies than in the optional 4.6-liter Northstar V-8, and the V-6 model will likely cost some $9000 less. Nine grand for 18 horsepower!? That rivals some of the deals you’ll find on Shelby Mustangs.

We are strong advocates of increasing power in all engines, but this is not an issue we take lightly. Engines cannot be merely stronger; we also prefer them to be smooth and considerate. In this, the STS delights, being noticeably more powerful—up 47 horsepower and 20 pound-feet on the powerplant it replaces—as well as higher revving (7000 rpm versus 6700), better sounding, and marginally more fuel efficient. All that on regular fuel, too.
