BMW unleashes the all-new 2025 BMW M5 Hybrid with 717 hp and 738 lb-ft of torque

BMW's 2025 M5 sedan is the most powerful model ever built

When the 2025 BMW M5 starts shipping in Q4 2024, it will be the most powerful version of the executive performance sedan ever sold. The new M5’s 717-hp hybrid powertrain is a significant step toward an all-electric version.

Why the M5 Hybrid matters

The 2025 BMW M5 hybrid power delivery may be an incremental advance, but it’s not a placeholder for the real deal. The market for all-electric cars is growing, but it is still quite small. The new M5 isn’t a solution for drivers who want better fuel economy — gasoline cost isn’t an issue for M5 buyers. M5 buyers will be attracted to its performance, including its suspension and handling braking, operating modes, assistance technologies, and much more.

It’s important to note that M5’s electric power exists to improve the car; the car doesn’t exist to support electrification. It’s wonderful that the M5’s hybrid powertrain improves the car’s performance significantly, but I seriously doubt that BMW engineers’ collective goal was to build a better hybrid. They focused on building a better car.

Notable features of the 2025 BMW M5

The new M5 has myriads of new or improved performance features, but it’s far beyond the scope of this article to cover them all. The hybrid powertrain is the headline feature, and I’ll stick to that.

The M Hybrid powertrain starts with a 4.4-liter V8 gasoline engine with two M TwinScroll turbochargers and a cross-bank exhaust manifold. The motor also has indirect charge air cooling, precision fuel injection, fully variable valve time, and variable camshaft timing. The engine creates 577 hp at 5,600 to 6,500 RPM and 553 lb-ft of torque across a wide 1,800 to 5,400 RPM range.

The electrical power system uses BMW Drive technology with a permanently excited electric motor integrated with the eight-speed M Steptronic transmission. There’s also a regen function to recapture energy for the 347.5V Lithium-ion. The battery has 14.8 kWh of usable energy and supports a maximum 7.4 kW charging rate. The electric motor creates a maximum of 194 hp and 207 lb-ft of torque. BMW ways the M5 can travel up to 25 miles solely on battery power.

When the two motors are both called on, the maximum output is 717 hp and 738 lb-ft of torque. According to BMW, all that power translates to 0-to-60 mph acceleration in 3.4 seconds. The top speed is electronically limited to 155 mph or 190 mph with the optional M Driver’s Package.

BMW will start production of the 2025 M5 in July 2024, and deliveries will start in November. The 2025 BMW M5 starts at $120,675, including destination and handling fees.

If the newest Toyota Crown nameplate sounds familiar, that's because it should. Replacing its former flagship, the Avalon, Toyota resurrected the Crown for 2023 after it has been absent from U.S. showrooms for a little more than half a century. For context, the Crown and the Landcruiser were the first two models Toyota sold in the States. Fast forward a bit, and the Japanese company has decided to add a new crossover hybrid SUV, known as the Crown Signia, to the Crown subdivision.

BMW i7 M70 xDrive

Last year, BMW unveiled the i7 -- a high-end, luxury, electric vehicle offering exquisite comfort in the back and high-end performance in the front. But some fans noticed something was missing. There wasn’t a “Motorsport” edition, so those looking for peak performance coupled with some iconic style touches may have felt like they were missing out. Fast forward to 2023, and the German automaker has rectified that problem.

If you have at least $168,500 available, you can get your hands on the BMW i7 M70 xDrive -- an all-electric, all-wheel-drive powerhouse. Like its basic BMW 7 Series brethren, the i7 M70 is capable of cruising along the highway smoothly in all conditions, allowing those inside to drink in the luxury touches on offer. Equally, you can put your foot down and take off at speeds you would expect from a small, supercharged Italian sports coupe.
