CTS Lineup for 2012

[automoblog]

Improvements to the engine are where the good stuff is at though. The CTS’ 3.6-liter V-6 made 304 horsepower and 273 pound feet of torque for 2011. For 2012, engineers added larger intake valves, a longer-duration intake camshaft and redesigned the intake port. These changes up the power level to 318 hp and 275 lb-ft, without sacrificing fuel economy.

The engine also drops weight, with to the tune of 20.5 pounds. The drop in weight is thanks to an integrated cylinder head/exhaust manifold made from composites, a lighter-weight structural front cover and high-strength connecting rods. Lighter weight is always a good thing, for fuel economy as well as the car’s weight distribution.

The CTS get some upgraded technology as well with Bluetooth now standard across the lineup and the availability for side blind-zone alert technology in the CTS Coupe.
