(April 13, 2011) DETROIT — Chevrolet Camaro will introduce a new model and a new engine for the 2012 model year. Included is an improved version of its standard 3.6-liter  direct injection V-6 engine, a new FE4 performance suspension package for SS coupes and several interior and technology improvements, such as a revised instrument panel design, new steering wheel and rear camera system.



The changes will arrive in time for Camaro’s 45th birthday, which will be celebrated with this summer’s release of the 45th Anniversary Special Edition Camaro.

The 45th Anniversary Special Edition carries all the upgrades for 2012, with additional unique design elements, inside and out. 

“The appeal of Camaro design and performance has powered it to the top of its segment,” said Rick Scheidt, vice president of Chevrolet marketing. “For 2012, we’re capitalizing on that momentum with enhancements to Camaro’s performance and comfort.”



Also coming in early 2012 is a high-performance Camaro ZL1, the most technologically advanced car ever developed in its segment, according to Chevrolet.



Camaro’s new 3.6-liter direct injection V-6 – the LFX engine — goes into production this summer. It delivers an SAE-certified 323 horsepower at 6,800 rpm — an increase of 11 horsepower over the 2011 engine. 



Chevrolet says the LFX will deliver the most standard power in the regular sports car segment. It is also 20.5 pounds lighter than its predecessor.  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.



According to Chevy engineers’ 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. The technology is used by a number of manufacturers.

The Camaro also uses a new fuel pump for the direct injection system, along with a new, isolated fuel rail. The new fuel pump is said to be quieter, while the isolated fuel rail can further reduce fuel system noise.
