There’s nothing ominous-looking about the Cadillac CT6 Platinum AWD sedan. It appears to be a normal executive car – a little heavy on the starch, maybe.

The body lines are crisp and the interior has a lot of standard luxury upgrades: semi-aniline leather seats, a Bose stereo system with 34 speakers and a semi-autonomous driver-assist feature.

It’s under the hood where things get interesting. Wedged into the engine compartment is a hand-built, 500-horsepower Blackwing V-8. The engine is so tightly packed that you couldn’t drop a dime through it to the pavement below.

Even more inspiring than the 500 horsepower is the blistering 574 pound-feet of torque which propels this heavy, 5,600-pound sedan from 0-to-60 mph in a mere 4.4 seconds.

Cadillacs are available locally at Integrity Cadillac on International Boulevard. Our Shadow Metallic CT6 was provided for a one-week test drive on Chattanooga streets and highways by the manufacturer.
