2020 Mercedes GLE Coupe
While Europeans can order the new GLE coupe with torquey and efficient diesel engines, the U.S. market gets only one choice: the AMG GLE53 coupe. It’s powered by the same 3.0-liter inline-six found in other AMG 53 models that is fitted with a 48-volt hybrid booster. For short bursts, the system adds a further 21 horsepower and 184 lb-ft of torque to the gasoline engine, which maxes out at 429 horsepower and 384 lb-ft of torque.
This powerplant conspires to achieve a claimed zero-to-60-mph sprint in 5.2 seconds, and top speed is an electronically governed 155 mph. Down the road, we expect AMG to add a GLE63 coupe model with a 4.0-liter twin-turbo V-8 that will also offer an even more powerful GLE63 S variant.
2020 BMW X6
Unlike the X5, the new X6 is available with rear-wheel drive in the form of the base sDrive40i model, which uses a 335-hp turbocharged 3.0-liter inline-six. The top-of-the-line model is the X6 M50i—there’s no “regular” 50i model—powered by a twin-turbo 4.4-liter V-8. It makes 523 horsepower and 553 lb-ft of torque, and BMW says it will hit 60 mph in 4.1 seconds, matching its claim for the new X5 M50i as well as the outgoing X6 M. All models use an eight-speed automatic transmission. When equipped with optional summer tires, all X6s have a top speed of 155 mph, as opposed to 130 mph without them.
