REPORTS OUT OF the US today suggest that GM is nearing completion of a new twin-turbo 3.0 litre V6 engine, bearing the Regular Production Option (RPO) code 'LF3' - possibly an extension of the naturally-aspirated 3.0 litre V6 LF1 engine offered in a number of GM models.
While specific power figures are unknown, American website GM Inside News reports that the new engine will rival Ford's new 272kW EcoBoost engine. For now, GM offers only a 2.8 litre V6 - in the Cadillac SRX - producing around 225kW and 400Nm of torque.
Production of the LF3 engine will reportedly begin in late 2011 or early 2012, with the upcoming Cadillac XTS likely to be the first model to gain the new engine.
Speculation in the media this week also suggests that GM might look to install the new engine into the Camaro, a rumour likely inspired by the twin-turbo 3.6 litre Camaro shown at last year's SEMA tuner and aftermarket parts show.
