AMG boss promises V12 engine will survive -- as a hybrid

New 4.0-liter V8 engine will see volume production, replacing current 5.5-liter mill.

Mercedes-Benz is reportedly preparing to use its new AMG-built 4.0-liter V8 across the lineup, while the current 6.0-liter V12 will be adapted for tighter emissions guidelines.

The twin-turbocharged powerplant initially debuts in the AMG GT, producing 456 horsepower and 443 lb-ft of torque for the base model. Consistent with other AMG engines, each mill is hand-built by an individual technician.

"The engine will replace our 5.5-litre engine," AMG head Tobias Moers told Autocar.

The company will switch to traditional assembly-line production as the 4.0-liter engine makes its way into other models, including lesser Mercedes-Benz offerings that lack an AMG badge.

Despite the switch to a lower-displacement V8 for many models, the company promises to keep the 6.0-liter V12 in the lineup. It will receive significant revisions to reduce fuel consumption, adding some form of hybrid technology.

Moers recently confirmed that AMG will eventually offer the GT in Black Series guise, though he now cautions that no Black Series models are currently under development. The executive also downplayed rumors of an all-wheel-drive variant and a diesel-powered edition.
