New York Motor Show: Cadillac CT6-V Sport debuts with new GM V8

Cadillac has revealed a new performance sedan, the Cadillac CT6 V-Sport, which itself has debuted a new engine for GM.

The new engine is a twin-turbo 4.2-litre V8, sporting an ‘estimated’ power output of 410kW and 850Nm of torque.

And it’s the engine that’s most exciting for us over here in the Land Down Under because, while it’s not likely we’ll see the car show up here, there’s a chance the engine will be used in other vehicles that could.

A Holden spokesperson recently told MOTOR’s sister publication Wheels that a rear-drive V8 would come to Australia under GM, though it “hasn’t committed to anything [specific] at this stage.”

“We’ve committed to introducing a rear-drive V8 into Australia, and I guess that’s as far as we can go,” they told Wheels.

So, a new rear-drive V8 from GM on the way to Australia, and maybe a new V8 engine to compete in the more modern turbocharged market.

The V8 features a ‘hot-vee’ configuration, similar to that utilised by AMG, which allows a more instant response as exhaust gasses have a shorter distance to travel and more energy can be retained.

It “transposes the conventional layout of the cylinder heads’ intake and exhaust systems to mount the turbochargers at the top of the engine — in the valley between the heads — to virtually eliminate turbo lag and reduce the engine’s overall packaging size,” Cadillac says.

Cadillac president Johan de Nysschen seems quite proud of the engine, so it’s more than likely we’ll see it used in other vehicles in the future.

“With the introduction of the all-new CT6 V-Sport, Cadillac begins a new chapter in its performance legacy with the introduction of the brand’s first-ever twin-turbo V-8 engine,” says de Nysschen.

“It is the centerpiece of the new CT6 V-Sport, an engaging sport sedan infused with DNA of Cadillac’s world-renowned and championship-winning motorsports program.”
