2014 Mercedes E63 AMG Delivers 577-HP Blast at 2013 Detroit Auto Show

Mercedes-Benz chose the hallowed ground of the Detroit Auto Show to unveil its redesigned 2014 E-Class, which is the brand’s second-most-popular nameplate in the U.S. The lineup includes sedan, wagon, coupe and convertible models, but that’s not all! The high-powered AMG version also got reworked, and was just revealed in Motown.

And we should really say versions because the company is now offering two flavors of this performance machine, hot and extra spicy. The regular E63 AMG 4MATIC (if there is such a thing) is hauled around by a 5.5-liter twin-turbo V8 engine that delvers 550 horsepower and 531 lb-ft of torque. This car is offered as a sedan only.

For extra-discerning drivers, Mercedes is making an S-Model available, which delivers even more performance. It uses the same basic poweplant as the standard AMG car, but engineers have made a few subtle tweaks resulting in even bigger numbers. Horsepower jumps to 577 and torque swells to 590 lb-ft, probably enough to stop the earth’s rotation. The extra output comes courtesy of a revised engine management system, higher peak injection pressure and increased boost. The standard car’s turbos deliver up to 13 psi; the S-Model’s blowers push out 14.5.

The E63 AMG should be able to sprint from zero to 60 miles an hour in just 3.6 seconds. It’s electronically limited to a top speed of 155 miles an hour. The S-Model sedan shaves one-tenth of a second off that time while wagon bodystyle clocks in at 3.6 seconds as well. The S-Model’s maximum velocity is a blistering 186 miles an hour.

Both engines are matched to an AMG Speedshift MCT seven-speed automatic transmission. As with other high-performance machines this car offers selectable drive modes. Altogether there are four settings: Controlled Efficiency, Sport, Sport Plus and Manual. Interestingly, the efficiency setting incorporates start/stop technology, which kills the engine when the vehicle is not moving, resulting in a noticeable improvement in fuel economy.

When it comes to efficiency no specific numbers have been shard, but Mercedes claims the car will deliver best-in-class performance and fuel economy. We’ll have to wait to see what the U.S. EPA has to say about that.

Managing the E63 AMG’s aerospace-grade power is a performance-oriented permanent all-wheel-drive system. It’s standard on all U.S. versions of the car. Torque split is 33 percent front, 67 percent rear, a balance Mercedes says delivers maximum driving pleasure. Racing-grade carbon-ceramic brakes eradicate excess velocity, and with a diameter of 14.2 inches make a bold design statement as well.

Both the E63 AMG and the even more insane S-Model should go on sale in the U.S. this summer. Pricing has not been announced.
