The seventh-generation BMW M5 has officially arrived, debuting as a plug-in hybrid super sedan. This model utilizes a powertrain similar to that of the XM SUV, combining a 4.4-liter S68 twin-turbo V8 with an electric motor mounted on the transmission. The 2025 M5 boasts an impressive output of 717 horsepower and 738 lb-ft of torque, with the V8 alone contributing 577 hp and 553 lb-ft, while the electric motor adds 194 hp and 207 lb-ft.
These specifications allow the M5 to reach a top speed of 190 mph with the M Driver’s Package (standard is 155 mph), and it can accelerate from 0 to 60 mph in 3.4 seconds. While this is still fast for a large sedan, it falls short of the outgoing non-hybrid M5, which achieved 60 mph in 3.1 seconds for the Competition variant and 3.2 seconds for the base model (with the M5 CS clocking in at an impressive 2.9 seconds). The notable difference in acceleration is likely due to the increased weight of the new M5, which weighs in at 5,390 pounds—almost 1,000 pounds heavier than its predecessor.
The hybrid system contributes to this weight increase, but BMW states it shares a close relationship with the M Hybrid V8 LMDh endurance racing car used in events like Le Mans. The all-electric range is estimated at about 25 miles, powered by a 14.8-kWh lithium-ion battery positioned in the underbody for a lower center of gravity. Unique engine and transmission mounts enhance performance, while a new Boost Control feature allows for rapid acceleration between 20 and 90 mph. Engaging the downshift paddle triggers the most aggressive settings in the car. Power is transmitted through an eight-speed automatic transmission and directed to all four wheels, with exhaust gases exiting via a new sport exhaust system.
While weight gains may impact initial acceleration, BMW emphasizes that electrification enhances performance at higher speeds, reporting a 50-to-75 mph time of just 2.2 seconds in fourth gear.
The new M5 is equipped with an advanced all-wheel-drive system that features a more efficient transfer case than previous models. Its Active M Differential can dynamically distribute torque between the rear wheels. Like its predecessor, the AWD system offers three driving modes: standard 4WD, 4WD Sport (which sends more torque to the rear), and 2WD, converting the car to rear-wheel drive.
The overall structure of the new M5 has been reinforced, while numerous strength-adding beams have been integrated into the engine bay, including a shear panel between the strut towers. The revised aluminum double-wishbone front suspension is stiffer, and the newly engineered wheel carriers improve stability. The five-link rear axle is tailored for the M5, aiding its ability to balance handling and ride comfort. Standard features include an Adaptive M suspension with electronic dampers that allow for near-instant adjustments to damping forces.
The steering system has also been upgraded to include variable ratio and speed-sensitive assistance. Rear-wheel steering has become standard, offering up to 1.5 degrees of turning angle for better maneuverability at low speeds and improved stability at higher speeds. The braking system has been revamped, incorporating an integrated braking system with standard M Compound brakes, while lighter and more durable carbon ceramic brakes are available. The M5 features staggered wheels measuring 20 inches at the front and 21 inches at the rear.
Aesthetically, the new M5 reveals a more aggressive exterior, highlighted by larger front air intakes and wider fenders, resulting in a front width increase of 3 inches and 1.9 inches at the rear compared to the standard 5 Series.
The base price for the 2025 BMW M5 starts at $120,675, with a public appearance scheduled for the Goodwood Festival of Speed in July, and it will be available at dealerships starting in November. Additionally, a wagon variant is in the works. Stay tuned for further updates..
