2011 Mercedes-Benz S63 AMG at Geneva

the 2011 S63 AMG will receive the company's all-new 5.5-liter bi-turbo V8 engine, as well as the SpeedShift MCT seven-speed gearbox already on offer in the E63 and SL63. Even though it's down on displacement compared to the outgoing 6.2-liter engine, the M 157 generates more power (544 horsepower in 'standard' mode, 571 with the optional performance package) and more torque (586 pound-feet or 660 lb-ft. with the optional performance pack). And despite the change in engine size, the big sedan's S63 moniker will remain. MB chairman of the board Volker Mornhinweg has also confirmed to Autoblog that the U.S. market will indeed receive start-stop technology despite the fact that its efficiency gains aren't really recognized by the EPA's fuel economy testing methodology. Even so, the user-defeatable fuel-saving measure ought to pay dividends in city traffic, which is important because cities like Los Angeles and New York are prominent AMG markets. Despite offering an embarrassment of performance, the S63 will also cut fuel consumption by an astonishing 25 percent, thanks in part to clever programming of its SpeedShift gearbox and a driver-selectable 'Controlled Efficiency' program, an eco-mode that, among other things, instructs the transmission to always start in second gear, shift up as quickly as possible, and remain in higher gears whenever possible. In addition, the Intelligent Generator Management System employed on the E63 is also used to funnel kinetic energy back into the battery, and there is a new generation of cylinder deactivation technology at work as well. All-in, the still-massive motor will turn in an impressive 23.5 miles-per U.S. gallon on the EU cycle and Morninweg pledges that the car will skirt U.S. gas guzzler taxes. The 'standard' S63 will run to a governed 155 mile-per-hour top end, while the performance package model has been let out to 186 mph. The new car is slated to go on sale in the second half of the year, and the 5.5-liter engine is expected to supplant the 6.2-liter in other AMG offerings over the next several years. We'll see the new engine tomorrow in person at the Geneva Motor Show, where it will reside in the engine bay of a special S63 showcar. The showcar (above) pays tribute to an early AMG-powered 300 SEL that won its class and finished second overall at the 1971 24-hour race in Spa-Francorchamps.

Mercedes-Benz S 63 AMG ''Thirty-Five'' meets 300 SEL 6.8 AMG
39 years after the 300 SEL 6.8 AMG placed second at the 24-hour race at the Spa-Francorchamps track in Belgium, Mercedes has partnered the car on the same circuit with a similarly dressed S 63 AMG showcar to commemorate the event. The second-place finish helped establish AMG as a serious player in German automotive history, which is now the in-house performance division of Mercedes-Benz. On the track, both cars were wearing the number '35' of the original 300 SEL 6.8 AMG and were driven by the same drivers, Hans Heyer and Clemens Schickentanz, who raced the 300 SEL back on July 25, 1971. The 300 SEL 6.8 AMG featured a 6835 cc engine with 315 kW (428 hp), 608 Nm of torque. The S 63 AMG showcar, based on the Mercedes-Benz S-Class full-sized sedan, comes with AMG's new 5.5 liter twin-turbo V8 coupled to a 7-speed SpeedShift MCT gearbox. That engine comes in two power configurations - a 'standard' set-up with (544 PS / 536 bhp) and 800Nm (590 lb-ft) of torque and the AMG Performance Package one with 420kW (571 PS / 563 bhp) and 900Nm (664 lb-ft) of twisting power. The new 2011 S 63 AMG goes on sale this September.
