Automotive News is reporting that GM has finally confirmed development of a V-12 that would be slated for higher-end Cadillacs in the not too distant future.
Based on the high-feature V-6 architecture (2.8, 3.6, 3.6 Direct Injection) family of engines, this V-12 would be mechanically similar to two 3.6l V-6’s joined at the crank. This would give displacements upwards of 7.2l and horsepower numbers in excess of 600hp.
The engine is currently undergoing testing in Australia in a modified Holden Commodore (Pontiac G8) – which is built on the same Zeta chassis that Bob Lutz has previously suggested might make a good basis for a high-end Cadillac.
Expect a decision to be made soon as to what model(s) the V-12 might make it into.
We’d expect a high-end sedan as the most likely, with an ultra Escalade, and a V-12, 2-seat super sportscar as other, less likely options.
