Chevrolet Camaro Zl1
The 2012 Chevrolet Camaro IS an improved version of the direct-injected 3.6 liter V6 LLT engine. Dubbed LFX and also standard in the Cadillac SRX and Chevy Impala, the powerplant has several advantages compared to the outgoing LLT, including.
1:New cylinder head design with integrated exhaust manifold
2:Improved intake port design and larger intake valves within the cylinder heads
3:Longer-duration intake camshafts
4:Composite intake manifold
5:New fuel pump and isolated fuel rail
6:New, optimized-flow fuel injectors
7:Structural front cover and cylinder block enhancements
8:Stronger and lighter-weight connecting rods
9:Camshaft cap and throttle body design enhancements
The LFX is good for for a whopping 323 horsepower (241 kW) at 6,800 RPM an increase of 11 ponies (8 kW) compared to the LLT without so much as a drop in fuel economy. The new engine, however, isn’t only about more power it’s also 20.5 pounds (9.3 kg) lighter than its predecessor, providing a more balanced driving experience.
Rounding out the powerplant changes are a new fuel pump for the direct injection system that’s quieter as well as a new isolated fuel rail system that reduces fuel system noise. The addition of the LFX puts the Camaro at the top of the pony car power wars in the V6 segment.
