Cadillac President Johan de Nysschen explicitly told media here at the 2018 New York International Auto Show that the brand’s new 4.2-liter twin-turbo LTA V8 engine is not bound for any Corvette. The executive aimed to squash any rumors that have circulated since the engine’s reveal last week with the 2019 Cadillac CT6 V-Sport.
The engine produces 550 horsepower and 627 pound-feet of torque in the V-Sport, though a 500-hp version will be optional in other Cadillac models.
de Nysschen said the engine focuses more on refinement and luxury, while the Corvette “wants a different kind of character.”
The idea behind Cadillac’s 4.2-liter twin-turbo V8 heading to the mid-engine C8 Corvette really gained momentum after a leaked IHS Markit report described a seemingly identical engine in the pipeline for the C8 Corvette. The report also mentioned the current 6.2-liter LT1 V8 engine and a 5.5-liter twin-turbo V8 engine.
Cadillac also threw fuel on the fire when it disclosed its new V8 engine would be built in Bowling Green, Kentucky, and General Motors’ Performance Build Center—the home of all things Corvette.
Still, de Nysschen may simply have shut down rumors for this specific engine. Engineers could certainly have a relative engine based on the LTA architecture in the works. We’ll simply have to wait and see.
