AC Schnitzer is back at it, turning up the heat on the latest BMW M5 Sedan and Touring with a fresh batch of upgrades. As if BMW’s new 717-hp hybrid M5 wasn’t wild enough, the German tuner is pushing it even further—all the way to 799 hp.

The secret sauce? Some clever ECU software tweaks and a new stainless steel exhaust system. It’s not a night-and-day difference, but you’ll definitely feel the extra muscle when you hit the throttle.

Looks haven’t been ignored either. Both the Sedan and Touring versions get a handful of sharp visual enhancements, starting with aggressive new front splitters and small aero canards to help keep things planted at speed.

A lowering kit drops the ride height by 20 mm; while that may not sound like much, the visual impact is significant. Add a set of AC Schnitzer’s forged AC6 wheels into the mix, and the whole stance transforms completely.

Those wheels come in either a sleek aluminum or gloss black finish, measuring 21×10.5 inches up front (wrapped in 285/35 tires) and 21×11 inches in the back (with 295/35s). If you’d rather keep the stock BMW wheels, no problem. AC Schnitzer also offers 7 mm spacers to help achieve the perfect fit inside the fenders.

At the rear, the updates continue. Both models feature new diffusers. In addition, the Touring gets a beefier roof spoiler, while the Sedan wears a subtle lip spoiler on the trunk. As for the cabin, you can opt for a few premium touches such as aluminum pedals, a stylish key holder, and a metal cover for the iDrive controller. It’s classic AC Schnitzer: sharp performance, clean style, and just enough to stand out without going overboard.
