Elmiraj Concept – 4.5l OHC Turbo V-8?

Automobile Magazine was able to get a new detail about the engine that is hidden away (in theory) beneath the hood of the Elmiraj concept that Cadillac displayed at the 2013 Pebble Beach Concours. Where we heard that the engine was simply a 4.5l twin turbo V-8, Automobile is reporting that the engine is also overhead cam in design.

Could Cadillac be bringing back the shelved replacement for the Northstar? That engine was supposedly well into development when GM decided to focus on direct injection V-6 and later turbo-charged variants.

Could a turbo V-8 be the mainstream engine for the Elmiraj’s production version (widely expected to be the S-Class/7-Series fighter based on GM’s Omega platform…yes, Cadillac will cheekily bookend their models with Alpha and Omega)? If so, would it be safe to assume the turbo V-8 would be the next CTS-V’s power plant of choice? Doing so would give the V-Series models an engine from the next model up’s lineup.

We should see more hints at Omega, its power train offerings, as well as future V-Series models in the coming year.
