The thirsty, high-power V8 Camaros will only be a part of sales, according to GM vice president of sales and marketing Mark LaNeve in an interview wtih Edmunds.
"Everyone thinks we'll be positioning the Camaro as a burn-ass hot rod," he said. "But that's only about 30% of the business. The other two-thirds will come from 27mpg V6 sales, with a significant female share."
The V6 LaNeve spoke of was spotted last week by spy photographers. A four-cylinder is also in the works, as Bob Lutz said in March. The precise nature of the smallest mill - or even if it will ultimately be used in the Camaro - isn't yet decided, but the most likely scenario is a 2.0-2.5L inline four with the aid of a turbocharger for better power while maintaining acceptable fuel efficiency.
The downsizing engine trend is something GM will be taking throughout its model line, as well. Powerful six-cylinder cars will replace V8s, and turbocharged or normally-aspirated fours will replace the older V6s. CAFE might not kill these cars, but it will force them to evolve by the time they arrive in 2010.
