Engine & Transmission
The CTS comes standard with a 3.0-liter V-6 engine, but our test car's optional 3.6-liter V-6 and six-speed automatic transmission are a special pair among drivetrains. The transmission's shifts are unobtrusive, and it's always in the right gear for the driving situation. The automatic is also incredibly responsive; press down on the gas pedal and it downshifts immediately. A lot of automatics make you wait before kicking down, which makes it refreshing to drive one that's so attentive to the driver's wishes.
The 3.6-liter V-6 has power in reserve for accelerating around other cars on the highway, and the transmission responsiveness remains. The sedan moves out well, and the V-6's mechanical growl sounds good in the process. This V-6 makes more power for 2012 — 318 horsepower, an increase of 14 hp — and is also 20 pounds lighter than its predecessor. The engine received a number of changes, including new cylinder heads with integrated exhaust manifolds, a composite intake manifold and lighter, stronger connecting rods.
With the automatic transmission, the 3.6-liter V-6 is rated at an EPA-estimated 18/27 mpg city/highway. That's slightly better than the 2012 Infiniti M37's estimate of 18/26 mpg, but it trails the ratings for the 2012 BMW 535i (21/31 mpg) and the 2012 Mercedes-Benz E350 (20/30 mpg). However, unlike those three models, the CTS can run on regular gas as opposed to more expensive premium fuel. Only the supercharged CTS-V requires premium.
