Cadillac ATS/CTS Get New 3.6 L V6 & 8-Speed Auto For 2016




2016 Cadillac ATS-V and CTS

The flagship Cadillac CT6 has not even made its production debut yet, but its powertrain and drivetrain technologies have already begun to trickle-down to the 2016 Cadillac ATS compact sedan and CTS mid-size sedan.

The 2016 Cadillac ATS and CTS sport sedans will receive the CT6’s redesigned 3.6 L V6 and a new 8-speed automatic transmission. The new powertrain is designed to increase fuel economy while lowering emissions and optimizing performance. A new automatic Stop/Start system and Active Fuel Management cylinder deactivation system helps the engine run more efficiently.

The current Cadillac ATS and CTS feature a 3.6 L V6, but the redesigned 3.6 L V6 features a stiffer aluminum block and stronger rotating assembly which includes a forged steel crankshaft, polymer-coated pistons, and high copper content, stinter-forged connecting rods.

The updated valvetrain includes a higher flow cylinder heads and a four-cam phasing system which allows for later valve closing, which improves the engine’s overall efficiency. Cadillac engineers estimate that the new engine produces 333 horsepower and 285 lb.ft. torque, which is an improvement over the current 3.6 L’s ratings of 321 horsepower and 275 lb.ft torque. Cadillac officials also claim that the new motor is 3 dB quieter than Infiniti’s 3.7 L V6, which was one of the engine’s many new benchmarks.

GM’s new Hydra-Matic 8L45 eight-speed is lighter than the current six-speed automatic, and delivers 5% better fuel economy ratings thanks to wider gear ratios.

The mid-level Cadillac ATS soldiers on with the turbocharged 2.0 L inline four-cylinder engine, but gets the new automatic Stop/Start system for 2016.
