The latest BMW M5 is a departure from tradition, featuring a plug-in hybrid powertrain borrowed from the flagship XM SUV. Despite a modest all-electric range, the new M5 boasts 717 horsepower and 738 lb.-ft. of torque, a significant bump from its predecessor. However, the added weight of the hybrid components raises concerns, with a curb weight of 5,368 pounds compared to the old model's 4,177 pounds. The M5's design has also sparked criticism, with questions about the kidney grilles and rear bumper. On the inside, the cabin remains largely unchanged from the standard 5 Series, with sporty accents and a unique upholstery choice. Early reactions from current M5 owners have been lukewarm, expressing disappointment in the new model's specs. Despite these concerns, the new M5's performance capabilities and advanced technology remain a point of interest for enthusiasts.
