The all-new BMW M5 goes hybrid, keeps the V8, but gains a lot of weight. This is the seventh-generation M5 and the first to be electrified in the model’s history. BMW haven’t gone full electric yet, keeping the 4.4L twin turbo V8 engine and coupling it with a 194 hp, 207 lb-ft e-motor integrated into the eight-speed transmission and fed by a 22.1 kWh battery pack. They combine to generate 717 hp and 738 lb-ft of torque.
