While carmakers have finally started paying attention to weight, they're not yet ready to give up on the horsepower wars, with the base version of BMW's next M5 believed to go past the 600hp mark.
BMW will achieve this output through a fettled version of the current M5's 4.4-liter twin-turbocharged V8 that is rated at 552hp (560PS) in regular trim reaching 592hp (600PS) on both the M5 "30 Jahre" limited edition and M6 Competition Package.
This means that if BMW presents a similar competition package or special edition of the next M5, it should easily have more than 650 ponies.
As if those numbers were not impressive by themselves, the new G30-codenamed 5-Series, upon which the M5 is based, will benefit from the same lightweight measures as the new 7-Series employing aluminum in the chassis and carbon-fiber reinforced plastic in the body to shed some 100 kg or 220 pounds over the current model.
