Hybrid V8 Means a Wild M5, But AC Schnitzer Wants More

The 2025 BMW M5 is no longer just a muscular gas-powered brute. With the G90 sedan and G99 Touring, BMW has added a plug-in hybrid twist to the formula, pairing a twin-turbocharged 4.4-liter V8 with electric power to generate a staggering 717 horsepower right out of the box. Whether you choose the sedan or the long-roof version, the result is a capable machine that blends Autobahn pace with electric efficiency.

But for AC Schnitzer, the M5's standard firepower wasn't enough. The German tuning firm, known for adding sharp edges to BMW's most capable models, has rolled out a preview of its full upgrade package for the new M5 duo. The result is a sedan or a wagon that's more powerful and noticeably beefier.

M5 Gets Angrier, Louder, and 82 Horses Stronger

As expected from AC Schnitzer, the German tuner is preparing a performance tune that will raise system output to 799 hp, or 82 more than the standard M5. The tuner hasn't fully revealed how this is achieved, but it's expected to come primarily from the combustion engine side, possibly boosting the 4.4-liter V8 to around 660 hp. Torque figures are still under wraps, but a bump over the stock 553 lb-ft is expected. The upgrade includes a full warranty, maintaining peace of mind even with the added firepower.

Visual changes are just as serious. The car gains a more aggressive front splitter, canard-style side wings, chunkier side skirts, and a new rear diffuser. The three-box sedan gets a trunk lip spoiler, while the family-oriented wagon receives a roof wing. Ride height is lowered by 0.79 inches front and rear via revised springs for sharper handling.

Wheels are replaced with forged 21-inch AC6 Lightweight sets, available in either glossy black or ceramic-coated natural aluminum. Wrapped in wide rubber, they're paired with optional spacers if you want to stick to factory wheels. The quad 4.3-inch "Carbon Sport" exhaust tips finish off the visual and aural drama.

In Development, But Coming Soon

Inside, you'll find aluminum trim pieces including pedals, an iDrive controller cover, and a matching key holder – minor but tasteful upgrades in keeping with the car's sharpened focus.

All components of the AC Schnitzer M5 package are currently in development, with pricing and availability to be announced later in 2025. As always, Schnitzer's upgrades serve as a more radical, performance-focused alternative to BMW's own M Performance Parts line.
