According to GM’s Bob Lutz, development work is ‘‘well under way’’ in Australia. The new V12 engine is essentially two GM 3.6L V6 engines mated together with a single crankshaft. Inside sources have revealed that the engine’s output will be roughly double that of a single V6, so expect to see around 523hp (390kW) and 680Nm (500lb-ft) of torque from its 7.2L of displacement.
The new model will be targeted at cars like the Mercedes-Benz S-Class and Lexus LS range, and will include crash avoidance and safety technologies as well as direct injection and cylinder deactivation features.
