Chevrolet Camaro

From Chevrolet press: The 2010 model year proved to be a very successful and exciting year for the segment-leading Chevrolet Camaro. For the 2011 model year, Chevrolet looks to expand the car’s popularity among consumers with the introduction of additional features.

The 2011 Camaro V-6 engine completed SAE certification testing and is now officially rated at 312 horsepower at 6500 rpm and 278 lb-ft of torque at 5100 rpm. This rating is eight horsepower higher than the previous year and also marks an increase in torque from the 2010 rating of 273 lb-ft.

“The 304 horsepower in the 2010 Camaro was actually a conservative rating on our end,” said Tom Sutter, GM V-6 chief engineer. “But we knew already that this award-winning engine produced at least the amount of power we stated, but now we’ve gone the extra step in certifying the engine for this application and have verified an additional 8 horsepower.”

The 3.6-liter V-6 with variable valve timing (VVT) and direct injection employs four independent cam phasers to change the timing of valve operation as operating conditions such as rpm and engine load vary. The result is linear delivery of torque, with near-peak levels over a broad rpm range, and high specific output (maximum horsepower per liter of displacement) supporting overall engine response and drivability. When combined, direct-injection and VVT enable an unmatched combination of power, efficiency and low-emissions in gasoline V-6 engines.

SAE certification is a voluntary power and torque certification procedure developed by the SAE Engine Test Code committee. This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. Chevrolet was the vehicle brand to begin using the procedure.

Earlier this year, Chevrolet introduced the Camaro Synergy Special Edition which is based off the concept displayed at the 2009 SEMA show in Las Vegas. The Synergy Special Edition is limited to a 1LT model, but the Synergy Green exterior color will be made available on all trim levels for a limited run during the 2011 model year.
