This is the new baby Caddy: The rear-wheel-drive 2013 ATS. Engine choices include -- and I never in a million years dreamed that I'd see a list like this in a Cadillac -- a 200 hp 2.5 liter four-cylinder, a 270 hp 2-liter turbo four, and our old familiar friend the 3.6 liter V6, here tuned for 320 horsepower. Options include manual or automatic transmissions and an FE3 sports suspension with dynamic magnetic-fluid shock absorbers. Compared to the CTS, the ATS is about 8" shorter and 4.5" narrower.
