Why did it fail, though? For starters, the internal combustion engine produces only 163 PS (161 horsepower) while total system output is rated at 204 PS (201 horsepower) and 350 Nm (258 pound-feet) of torque. It’s not exactly terrible, but it’s not great either for a mid-size vehicle from a premium-oriented marque. Secondly, the 520e badge simply doesn't have the magnetism of higher specs like the aforementioned 545e.
Codenamed G30 for the sedan, the seventh-generation 5 Series is on its last legs, given that it entered production almost six years ago. BMW is currently putting the finishing touches on the G60 family that will include the G61 station wagon. What's more, the i5 EV is coming as well.
Expected to launch in 2023, the all-new 5er is rumored with two high-performance PHEV options. The first of the lot is tentatively dubbed 550e. In combination with a B58 straight-six turbo engine, this variant may produce in the ballpark of 450 horsepower. The second high-performance PHEV should come in the guise of the M5, which is expected to feature the S63 twin-turbo V8 of the BMW XM with 750-odd metric ponies on deck.
Torque is estimated at 1,000 Nm (737 lb-ft), which falls short of the 1,470 Nm (1,084 lb-ft) rating of the Mercedes-AMG GT 63 S E Performance.
