It’s no secret that the Chevrolet Camaro has weight problems when compared to the Ford Mustang. So, engineers have decided to update its direct-injected 3.6L V6 engine.
Gone is the LLT variant of the 3.6L V6 in favor of the highly anticipated LFX version. With the new engine, the 2012 Camaro V6 is SAE rated at 323 horsepower — a total punch in the Mustang’s face, whose V6 engine is only good for 305 HP and a jump of 11 horsepower from the LLT. Torque numbers have yet to be made official, but we’re hoping for somewhere in the ballpark of 280 pounds-feet.
With the extra boost in power, you’d think that the Camaro would sacrifice fuel economy in the process. It doesn’t. Rather, it’s improved with a 30MPG rating on the 2LS model. The LFX engine is also 20.5 pounds lighter than the LLT.
What gives the LFX more mojo for the 2012 Camaro can be credited towards several mechanical improvements, including a new cylinder head design with an integrated exhaust manifold, an improved intake port design and larger intake valves within the cylinder heads. We also see a new fuel pump system and isolated fuel rail, new fuel injectors and a composite intake manifold. Rounding out the improvements are stronger, lighter connecting rods, a camshaft cap and throttle body design enhancements.
