Mercedes-AMG E63 S sedan
Mercedes-Benz’s latest E-class sedans went on sale in June and now the automaker has shed light on the high-performance variants.
The high-end E63 S is powered by a 4.0-liter V-8 biturbo engine that produces 603 hp and 627 pounds-feet of torque. It can hit 60 mph in 3.3 seconds and tops out at 186 mph.
The base E63, meanwhile, is rated at 563 hp and has 553 pounds-feet of torque. It can reach 60 mph in 3.4 seconds but has a governed top speed of 155 mph.
Both models, Mercedes said, are the most powerful E-class variants of all time.
"The new E63 models represent the biggest step forward we've ever taken from one generation to the next,” said Tobias Moers, chairman of Mercedes-AMG, in a statement. “Vehicle dynamics were especially important to us.”
While the performance of the 2018 Mercedes-AMG E63 and E63 S vary, the two do share some similarities.
The engines have been equipped with the AMG Cylinder Management cylinder-deactivation system, which debuted on the SLK55, and it allows for lower fuel consumption.
A re-engineered AMG sport suspension is also found in the sedans.
Both models also feature the new AMG performance 4MATIC+ all-wheel-drive system which allows for torque distribution on the front and rear axles to be fully variable for the first time, Mercedes said. Two twin-scroll turbochargers boost performance and improve responsiveness.
The sedans also feature an AMG Speedshift multi-clutch technology 9-speed sport transmission, which is combined with a wet start-off clutch for the first time.
Drift mode is standard on the E63 S and when activated, the sedan becomes “purely rear-wheel drive,” Mercedes said.
In terms of design, the hood is inset like on a coupe, another first for an AMG sedan. There is a new radiator grille, giving the wide front fascia an aggressive look.
The E63 sedan will make its world premiere at the Los Angeles auto show next month.
The sedans are set to launch at U.S. dealerships during the summer of 2017. Pricing will be announced later.
