Cadillac planning supercharged V8 CT5

New CT5 sedan expected to score 477kW 6.2-litre supercharged V8

Cadillac planning supercharged V8 CT5

Cadillac might be about to lead General Motors’ electric vehicle charge but there’s one last petrol-powered hurrah coming from the current generation.

Reports out of the US are suggesting an ultra-high performance variant of the Cadillac CT5 is on its way using the 6.2-litre supercharged LT4 V8 from the Chevrolet Camaro ZL1 and now-defunct Cadillac CTS-V.

Media and consumers were left underwhelmed by the recent reveal of the CT5-V, a quick car with 265kW/542Nm from a 3.0-litre twin-turbo V6, but a long way from the 477kW/855Nm offered by its previous CTS-V super sedan.

As it turns out, the CT5-V was just the entrée with the main course still to come, Cadillac telling US media that it has switched to a two-tiered line-up for its high-performance models, with the yet-to-be-named track capable models yet to appear.

It’s expected the CT5 will adopt the LT4 V8 while the smaller CT4 will use the 3.6-litre twin-turbo V6 from the previous-generation ATS-V which produced 346kW/601Nm. Cadillac offered a first look at these two new models when prototypes completed laps at the recent Detroit IndyCar Grand Prix driven by GM President Mark Reuss and Product Vice President Ken Morris.

There was speculation that high-performance Cadillac variants would be powered by its new 4.2-litre twin-turbo V8 dubbed ‘Blackwing’, but that engine’s future is in serious doubt as the car it powers, the flagship CT6-V, was revealed and then almost immediately cancelled.

Jonny Liebermann from US outlet Motor Trend reported on his Instagram both the future CT4 and CT5 high-performance variants will be offered in both manual and automatic. The CTS-V and ATS-V were both available as a six-speed manual or eight-speed automatic, however, the LT4-powered Camaro ZL1 uses a new 10-speed automatic.

GM revealed in its 2018 earnings report that “Cadillac will be GM’s lead electric vehicle brand and will introduce the first model from the company’s all-new battery-electric vehicle architecture” but apparently it’s still happy to keep at least one wheel in the traditional ICE camp for now.
