BMW's electric lineup has a new top dog. The 2024 i7 M70 xDrive, debuting at the Shanghai auto show, will become BMW's most powerful EV when it launches in the second half of this year. The luxury sedan's two electric motors combine for 650 horsepower, superseding the 536-hp i40 M50—which BMW says is the M division's global best-seller—and 610-hp iX M60. The M-specific 483-hp rear unit will also become BMW's most powerful electric motor.
