You knew it would only take time before General Motors took on Ford and its EcoBoost engine, and that time has just about come reports GMInsideNews. According to GMI's sources inside General Motors, the automaker is currently in development of a 3.0-liter V6 with twin-turbochargers. There's no word on actual output, but the same sources say it should rival the larger (3.5-liter) Ford powerplant. Ford's EcoBoost engine makes 365-hp in the SHO and was designed as a V8 replacement.

The engine's code is LF3, in direct reference to the LF1 direct-injection 3.0L V6 currently offered in several GM products.

Currently GM offers a turbocharged 2.8-liter V6 in the Cadillac SRX (above), which makes 300-hp and 295 ft-lbs of torque, so a reasonable bump over that output is certain.

This new twin-turbo V6 is expected in the flagship Cadillac XTS around 2012 and is likely to be used in several other GM products, including the upcoming 3 Series fighter, the ATS. In addition, there's even a strong possibility that such a motor could find its way into the Camaro – something which was previewed at last year's SEMA Show, when GM showed a twin-turbo 3.6-liter V6 stuffed under the hood of the muscle car.
