V-6 engine and class-exclusive eight-speed automatic. This second generation of Chevrolet’s double-overhead-cam engine architecture retains the same 3.6L displacement as before, with improved variable valve timing for intake and exhaust, improved direct injection and Active Fuel Management (cylinder deactivation), which disables two cylinders under light throttle applications. Horsepower and torque increase to a 308 hp and 275 lb-ft.

The GM-developed Hydra-Matic 8L45 is roughly the same size and weight as the 6L80 six-speed automatic it replaces. However, the eight-speed automatic offers a wider 7.0 overall gear ratio spread giving a higher first gear ratio and lower rear axle ratios that reduce engine rpm on the highway for improved efficiency. The 2017 model year updates, including the new V-6 and eight-speed combination, will arrive at dealerships this fall.
