Camaro may get 4-cyclinder engine

General Motors is considering a four-cylinder engine for the new Chevrolet Camaro as a response to rising fuel prices.

Speaking on the sidelines of the New York auto show, GM Vice Chairman Bob Lutz said the drivetrain under consideration for the Camaro is the same high-performance one used in the Pontiac Solstice and Saturn Sky roadsters. It’s a 2.0-liter turbocharged, direct-injected four-cylinder rated at 260 hp. Lutz said that if fuel prices continue to climb, the four-cylinder Camaro could see production.

GM has said it plans V8 and V6 versions of the Camaro but otherwise has been secretive. Lutz confirmed to Automotive News that the V6 version of the Camaro will be powered by the same high-tech V6 used in the Cadillac CTS. It’s a direct-injected, 3.6-liter four-cam V6. In the CTS, the engine is rated at 304 hp.

Low-priced version dropped
In the Camaro, the 3.6 liter’s horsepower should be around 260, Lutz said, Fuel economy, he said, will be around 17 mpg city and 25 highway. That would place the V6 Camaro among best in class for a performance car.

Lutz said GM has dropped plans to offer a low-priced, entry-level Camaro with one of GM’s low-tech V6s. GM will position both the V6 and V8 versions of the Camaro as premium cars compared to the Camaro’s chief rival, the Ford Mustang.

The base model Mustang uses a 4.0-liter overhead-cam V6 rated at 210 hp. The base model Dodge Challenger, due in the fall, will use a 250-hp, 3.5-liter V6.

Most enthusiast attention has focused on the Camaro’s V8 engine, which is likely to be a 6.0-liter with about 400 hp. Lutz said the V8 will have a cylinder cutoff system that shuts down half the engine when the car reaches cruising speed. That will help it get better fuel economy. More at AutoWeek
