The arrival of the 2019 Mercedes-Benz CLS is significant in many ways. Perhaps the most meaningful is the introduction of a new family of turbocharged 3.0-litre inline-6-cylinder gasoline engines for Canada.
The basics are identical for both versions. The 450’s mill sports a twin-scroll turbo and produces 362-horsepower and 369 lb.-ft. of torque while the 53’s block gets twin-turbochargers, good enough to bump power to 429-horsepower and 384 lb.-ft. of torque. Although the jump in output isn’t that huge on paper, under foot and on the road, the difference is noticeable.
