Recently we learned this week that the 2019 Cadillac CT6 V-Sport will feature a new dual overhead cam, twin turbo V8 with a reverse cylinder head design, all of which are expected features of the powerplant in the rumored mid-engine Corvette.
he Cadillac CT6 is a beautiful luxury sedan and for the 2019 model year, the range-topping model finally joins the V family – sort of. It isn’t a CT6-V, but the new CT6 V-Sport packs the new 10-speed automatic transmission, a uniquely tuned magnetic ride control suspension system, Brembo brakes and – most importantly – a new twin turbo V8 engine.
Right now, the 2019 CT6 is the only car officially slated to get the new twin turbo V8, but it seems unlikely that General Motors would take on the cost and effort of designing a V8 that is so different from the rest of their V8 engines. It seems likely that the new 4.2-liter twin turbo V8 will eventually be offered in something else and with the rumored mid-engine Corvette expected to arrive with a very similar engine – this could be our first look at the next generation supercar engine.
The Mid-Engine Rumors
Once again, I want to start by pointing out that GM has never offered up any official information on the existence of a mid-engine Corvette project, but videos and spy shots suggest that the company is definitely working on some sort of sports car with an engine mounted behind the driver’s seat. On top of those spy pictures and videos, CAD images showing what is believed to be the mid-engine Corvette surfaced online late last year and those colorful images included a twin turbo V8 with a dual overhead cam design and reversed cylinder head air flow.
