In a world of boxy crossovers, the fastback GLE43 and GLE63 S are welcome peculiarities. These performance powerhouses have the muscle to match, too. A 362-hp 3.0-liter twin-turbo V-6 and a nine-speed automatic power the GLE43, while the GLE63 S gets a mighty 577-hp 5.5-liter twin-turbo V-8, a seven-speed automatic, and in our testing hit 60 mph in just 3.8 seconds. All-wheel drive is standard. High-tech features like adaptive braking and collision prevention help you keep the shiny side up.
