We first told you about this engine in May, when Chevrolet announced its intention to replace an aging 4.3L V6 with this new engine, but now we know how the four-cylinder’s fuel economy stacks up against that of its competition.

Chevy’s fuel consumption estimates for the 2.7L — which is standard in LT and RST trims — are 11.9/10.3 L/100 km (city/highway) with 2WD and 12.5/10.8 with 4WD.

That’s a big improvement on the old V6 both in terms of economy and power: the new motor makes 310 hp and 348 lb-ft of torque (up from the old V6’s 285 hp and 305 lb-ft) and comes with max tow and payload ratings of 3,266 and 1,034 kg, respectively.

Chevy says the new engine boasts cylinder deactivation, a turbo designed for strong throttle response and “virtually no turbo lag,” active thermal management to recover wasted exhaust heat and automatic stop/start, all of which are conceived to maximize the engine’s efficiency.

But while Chevrolet says those features contribute to better city fuel economy than the Ford F-150 fitted with its entry-level 3.3L V6, Ford’s optional 2.7L turbo V6 is both more powerful (325 hp and 400 lb-ft) and more efficient, with consumption estimates of 11.9/9.0.
