Quick answer: The 2025 BMW M5 (G90 generation) starts at a base MSRP of $119,500 (excluding a $1,175 destination charge, bringing the total starting price to $120,675). For the first time in M5 history, the sedan adopts an electrified plug-in hybrid (PHEV) powertrain, producing a combined 717 horsepower and 738 lb-ft of torque. However, the hybrid hardware introduces a severe weight penalty, pushing the curb weight to 5,390 pounds, which slows its official 0-60 mph acceleration to 3.5 seconds. The vehicle offers an EPA-estimated electric-only range of 25 miles.
Key takeaways:
- PHEV Powertrain: A 4.4-liter twin-turbo V8 engine and an integrated electric motor generate a combined 717 hp and 738 lb-ft of torque.
- Weight Penalty: Curb weight increases to 5,390 lbs (up 1,045 lbs from F90), which negatively impacts the power-to-weight ratio.
- Acceleration: The official 0-60 mph sprint is rated at 3.5 seconds, which is slightly slower than its purely gas-powered predecessor.
- Electric Driving: An 18.6-kWh usable lithium-ion battery delivers up to 25 miles of zero-emission electric range.
- Value Proposition: The base MSRP of $119,500 is highly competitive, starting over $70,000 lower than the Porsche Panamera Turbo E-Hybrid.
2025 BMW M5 Engine, Horsepower, and PHEV Powertrain
The core of the new G90 M5 is its new M Hybrid system, which marks a significant departure from previous gas-only generations. The system pairs a high-revving 4.4-liter V8 engine featuring TwinPower Turbo technology with an electric motor integrated directly into the eight-speed M Steptronic transmission.
The twin-turbocharged V8 engine alone generates 577 horsepower between 5,600 and 6,900 rpm, and 553 lb-ft of torque from 1,800 to 5,400 rpm. The electric motor contributes 194 horsepower and a nominal torque rating of 207 lb-ft, though a pre-gearing stage can increase effective torque to 332 lb-ft at the transmission input. Combined, the hybrid system produces a massive 717 horsepower and 738 lb-ft of torque. According to MotorTrend, this electrified setup makes the G90 generation the most powerful production M5 ever built.
Power is sent to all four wheels through the rear-biased M xDrive all-wheel-drive system. Drivers can adjust the torque distribution to suit their driving preferences, including a traditional 4WD mode, a 4WD Sport mode that routes more torque to the rear axle, and a pure 2WD mode that disconnects the front axle entirely for classic rear-wheel-drive handling.
Battery Capacity, Electric Range, and Charging Times
The new hybrid sedan features a high-voltage lithium-ion battery pack mounted low in the chassis to help keep the center of gravity as low as possible. The battery has a gross capacity of 22.1 kWh, of which 18.6 kWh is usable net capacity.
According to official specifications verified by MotorTrend, this battery capacity provides an EPA-estimated electric-only range of approximately 25 miles on a full charge. This allows owners to complete short daily commutes or run local errands entirely on electric power without using gasoline. Under electric-only operation, the M5 can reach speeds of up to 87 mph.
Charging the battery pack is handled by an onboard AC charger that supports up to 7.4 kW. When connected to a compatible Level 2 charger, the battery can be charged from 0% to 100% in approximately three hours and 15 minutes. The 2025 M5 does not support DC fast charging, meaning owners will need to rely on home wallboxes or standard public AC charging stations. Drivers can choose from three hybrid operating modes: Hybrid (default automatic power management), Electric (pure zero-emission driving), and eControl (which maintains battery charge for later use).
Performance, Weight, and Acceleration: The Weight Dilemma
While the hybrid powertrain delivers record-breaking power outputs, it comes at a significant cost: weight. The 2025 BMW M5 sedan has a curb weight of 5,390 pounds, which is a massive 1,045-pound weight increase over the previous-generation F90 model (which weighed 4,345 pounds).
Analysis: To understand how this added weight affects performance, we can compare the power-to-weight ratios of the two generations. The old F90 M5 Competition generated 617 horsepower and weighed 4,345 lbs, yielding a ratio of 0.142 hp per pound (or 7.04 lbs per horsepower). The new G90 M5 generates 717 horsepower but weighs 5,390 lbs, resulting in a ratio of 0.133 hp per pound (or 7.52 lbs per horsepower). This represents a 6.3% decrease in the power-to-weight ratio.
This drop in the power-to-weight ratio explains why the 2025 M5 is officially slower from 0-60 mph than its predecessor. According to Car and Driver, the G90 sedan has an official 0-60 mph acceleration time of 3.5 seconds. In comparison, the older F90 M5 Competition achieved a 0-60 mph sprint in 3.1 seconds in official tests, and the lightweight M5 CS did it in 2.9 seconds.
Despite the weight penalty, the 2025 M5 remains an incredibly fast machine. The standard electronically limited top speed is 155 mph, which can be raised to 190 mph by selecting the optional M Driver’s Package. To manage the heavy curb weight in corners, BMW equips the M5 with standard M Adaptive Suspension, active roll stabilization, and Integral Active Steering (rear-wheel steering), which rotates the rear wheels up to 1.5 degrees to enhance agility at low speeds and stability at high speeds.
2025 BMW M5 Pricing and Competitor Analysis
The 2025 BMW M5 sedan starts at a base MSRP of $119,500. After adding the standard $1,175 destination and handling charge, the starting price comes to $120,675, as reported by Car and Driver.
Note: This price is for the standard sedan configuration. Optional packages, such as the Carbon Fiber Executive Package, Carbon Ceramic brakes, and individual paint finishes, can easily push the final MSRP past $140,000.
When compared to its closest plug-in hybrid competitors, the 2025 M5 represents a strong value proposition:
- Porsche Panamera Turbo E-Hybrid: Starts at a base MSRP of $191,000. It produces 670 horsepower and sprints from 0-60 mph in 3.0 seconds.
- Mercedes-AMG E 63 S E Performance: Expected to compete in the same price and performance bracket, utilizing a similar high-performance hybrid setup.
While the Porsche Panamera Turbo E-Hybrid is half a second quicker to 60 mph, the BMW M5 is priced over $70,000 lower while offering 47 more horsepower. This pricing strategy makes the M5 an attractive option for buyers seeking hyper-sedan performance without paying exotic-car prices.
Interior Comfort, Tech, and Cargo Limitations
The cabin of the new G90 M5 combines luxury with high-performance styling. The dashboard is dominated by the BMW Curved Display, which houses a 12.3-inch digital instrument cluster and a 14.9-inch central touchscreen. The system runs BMW’s iDrive 8.5 operating system, complete with M-specific graphics, driving mode menus, and hybrid energy flow displays.
Drivers receive a newly designed flat-bottomed M leather steering wheel with a red center marker, gearshift paddles, and programmable M1 and M2 buttons for quick access to customized driving modes. Standard equipment includes heated and ventilated M Multifunction sport seats, a head-up display, and customizable ambient lighting.
However, the PHEV packaging forces a compromise in cargo capacity. Because the rear electric motor and battery components sit underneath the trunk floor, the cargo volume drops to 16.5 cubic feet (466 liters) in the G90 sedan, down from 18.7 cubic feet (530 liters) in the previous F90 generation.
BMW M5 Lineup and Heritage
The M5 has long been the benchmark for high-performance midsize sedans. If you are looking at previous model years, the previous F90 generation, including the 2022 BMW M5 and 2023 BMW M5, represents the peak of gas-only performance, powered by the 4.4-liter twin-turbo S63 V8 without any electrical assistance.
For drivers looking for the latest advancements, the 2026 BMW M5 carries forward the G90 generation’s plug-in hybrid platform with minor software updates. You can explore the entire range of performance sedans at the official BMW M5 category hub.
