The new General Motors is apparently preparing a 3.0-litre twin turbo motor as a rival for Ford's 3.5-litre Ecoboost engine.

A rumour says General Motors is finally joining other major motor manufacturers with a twin turbo six-cylinder engine. According to, a direct injection 3.0-litre V6 twin turbo engine is being developed to compete with Ford's 3.5-litre Ecoboost motor which makes 355 hp (265 kW / 360 PS) in the Ford Flex, Lincoln MKS, and Lincoln MKT.  In the Ford Taurus SHO it produces 365 hp (268kW / 370 PS)

No power figures were reported yet but a few years ago there were rumours of a 3.6-litre twin turbo V6 from GM worth 435 hp (324 kW / 441 PS).

The new engine is said to carry the codename LF3, an extension of the existing naturally aspirated 3.0-litre's LF1 code. Should it come to market it will likely debut in a Cadillac, most probably in 2011 or early 2012. A few candidates for first use include the Cadillac XTS and the Chevrolet Camaro.
