The engine family will also get a refresh when the G30 5 Series hits the market. BMW is grouping 500cc cylinders together to create three-, four- and six-pot engines, with 60% common parts. A 2.0-litre four-cylinder will power the 520d and 231 hp 525d, while the leading petrol four is a 272 hp 528i. A three cylinder engine will power a 518d with around 150 horsepower.
Engine size dictates which suspensions slot into place: smaller-engines 5-series share front axles with the next 3-series, but go for a six- or eight-cylinder 5-series and you’ll get the front axle from the next 7-series instead.
But the biggest news today come from a source close to the brand who says the top model 550i will be replaced by an M550i, essentially a high-end 5 Series tuned by the M Performance Automobile division. Under the hood, the 2017 BMW M550i is said to have a revised version of the N63 4.4 liter V8 TwinTurbo engine which produces (preliminary number) 455hp. The rear-wheel drive platform is standard, but an optional all-wheel-drive xDrive is likely to be offered as well. BMW’s M Performance Automobiles are offered with a higher power output, tuned suspension, M aero parts and in some models (M235i), an optional limited slip differential.
Just last week, we learned that BMW might offer an M760Li model to sit at the top of the new 7 Series family, so this could be an indication of where BMW is heading with their non-M high-powered cars.
