Mercedes-Benz: New, naturally aspirated V8 for AMG


Mercedes-Benz will introduce a new, naturally aspirated V8 for all AMG models.

Mercedes-Benz has selected the twin turbocharged 5.5-liter V8 engine to power the recently unveiled S63 AMG, CL63 AMG and CLS63 AMG, with ratings between 525 hp and 577 hp.

But it’s going to be a different story for the successor to the SLK55 AMG set to be revealed at next year’s Frankfurt motor show. Sources within the Stuttgart headquarters suggest the new performance roadster is earmarked to receive a yet-to-be revealed naturally aspirated version of Mercedes-Benz’s new 5.5-liter V8.

Tuned by AMG’s powertrain department, it is claimed to deliver about 422 hp– 62 hp more than the 5.4-liter V8 used by the outgoing SLK55 AMG. Among the developments featured on the new 90-degree engine is a cylinder cut-off mechanism conceived to lower consumption.
