Here’s an American answer to the super saloons from AMG and M, and as always, it’s a Cadillac. GM’s luxury brand has unveiled the 2019 Cadillac CT6 V-Sport, the first-ever V-Performance model of its range-topping sedan. The introduction of the high-performance variant coincides with a facelift of the CT6 range that incorporates the design language from the Escala Concept.

The CT6 V-Sport is powered by a 4.2 litre twin-turbo V8 estimated at 550 hp and 850 Nm. That’s definitely in the ballpark currently occupied by the Mercedes-AMG E63 S (4.0 V8, 604 hp, 850 Nm) and BMW M5 (4.4 V8, 600 hp, 750 Nm). The motor is mated to the 10L90 Hydra-Matic 10-speed automatic transmission. Performance figures were not released.

The clean-sheet design V8 has a Euro-sounding “hot V” configuration that 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.

The latest CT6 is distinctly Cadillac in appearance, with front and rear vertical light signatures, but the V-Sport looks extra menacing. Lower aero components and gloss black window surrounds give a dark look, and it rides on 20-inch V-Sport wheels with summer-only UHP tyres.

The V-Sport also gets a mechanical limited-slip rear differential, V-Sport specific suspension, new 19-inch monoblock four-piston Brembo brakes, modified steering and Magnetic Ride Control damper settings, and an exhaust system with active valves. The latter offers reduced back pressure and more sound character, Cadillac says.

It might be strange to see “Cadillac” and “track” in the same sentence, but here it is. The new CT6 V-Sport gets track-tuned Active Rear Steer, revised AWD torque split and unique, track-focused stability controls.
