AMG's New Biturbo V8
Just the Facts:
AMG's new twin-turbocharged 5.5-liter V8 was unveiled in Germany.
In standard issue, it will deliver 536 horsepower and 590 pound-feet of torque.
The biturbo V8 will first appear in the new S63 AMG.
AFFALTERBACH, Germany — Mercedes-Benz will introduce a new version of the S63 AMG this summer, powered by AMG's new twin-turbocharged 5.5-liter V8. The new engine was showcased last week in a preproduction version of the new S63 AMG.
The biturbo 5.5 replaces the naturally aspirated 6.2-liter V8 in the current 2010 S63 AMG, which delivers 518 hp and 465 lb-ft of torque.
Also fitted with gasoline direct injection, the new engine is considerably more potent, despite its smaller displacement. In standard issue, it will deliver 536 hp and 590 lb-ft of torque. With the AMG Performance package, which hikes boost pressure from 1.0 to 1.3 bar, output rises to 563 hp and torque to 664 lb-ft.
Performance is also exceptional. Acceleration from zero to 60 mph is accomplished in less than 4.5 seconds, with top speed electronically limited to 155 mph. The AMG Performance package trims the 0-60-mph time by 0.1 second but raises top speed to an electronically limited 186 mph.
AMG also observes that its new biturbo V8, in combination with the Speedshift MCT seven-speed gearbox fitted with a stop-start function, has a combined fuel-economy average of 22 mpg — a 25-percent improvement over the current S63 AMG.
Inside Line says: In a rapidly changing world for performance vehicles, the real achievement here may be the significant increase in fuel economy. — Paul Lienert, Correspondent
