Displacing 2.7 liters, the long-stroke forced-induction inline-four is an all-new unit that General Motors said was designed specifically for truck applications. It packs a solid punch with 310 horsepower and 348 lb-ft of torque—just 35 lb-ft shy of the optional 5.3-liter V-8—that is available from as low as 1500 rpm and continues to 4000 revs. The engine is paired exclusively with an eight-speed automatic transmission.
