GM's New 323HP V6

 New and improved direct injection, VVT V-6 makes 323 HP!

The Camaro’s new 3.6L direct injection V-6 – the LFX engine – goes into production this summer. It delivers an SAE-certified 323 horsepower (241 kW) at 6,800 rpm – an increase of 11 horsepower (8 kW) over the 2011 engine, with no compromise in fuel economy.

The LFX delivers the most standard power in the regular sports car segment. It is also 20.5 pounds (9.3 kg) lighter than its predecessor, which promotes a more balanced driving experience. EPA-estimated highway fuel economy for the ’12 Camaro is 30 mpg (2LS model).

Compared to the 3.6L V-6 in 2011 models, the new LFX engine features:

• New cylinder head design with integrated exhaust manifold
• Improved intake port design and larger intake valves within the cylinder heads
• Longer-duration intake camshafts
• Composite intake manifold
• New fuel pump and isolated fuel rail
• New, optimized-flow fuel injectors
• Structural front cover and cylinder block enhancements
• Stronger and lighter-weight connecting rods
• Camshaft cap and throttle body design enhancements.

Direct injection is the key technology enabling the engine’s combination of power and efficiency. It optimizes fuel delivery to the combustion chamber by introducing fuel closer to the combustion chamber. The result is better efficiency in the combustion process leading to increased fuel efficiency at part and full throttle. It also uses a new fuel pump for the direct injection system, along with a new, isolated fuel rail. The new fuel pump is quieter, while the isolated fuel rail further reduces fuel system noise.
