AC Schnitzer BMW M5 G90 & G99: A Tuning Masterpiece with Bully Looks and 799 Horsepower

 AC Schnitzer is no stranger to the art of precision tuning. For decades, the German outfit has been taking BMW’s already world-class machines and sharpening them to an edge that sits just short of excess — perfect for discerning drivers who want more without sacrificing usability. The arrival of the new BMW M5 generation, the G90 saloon and G99 Touring, presented the perfect canvas for AC Schnitzer’s next masterpiece. The result is a package that combines brutal power, improved dynamics, tasteful design, and a host of functional upgrades that transform the M5 into something even more special. Even though the package is still under development as of July 2025, what has already been revealed offers an enticing glimpse into what’s coming. The M5 G90/G99 starts out as an already formidable machine with a 4.4-litre twin-turbo hybrid V8 delivering 727 hp. AC Schnitzer aims to lift that figure to an astonishing 799 hp (596 kW) while preserving reliability and offering their renowned warranty. It’s a balanced philosophy: more power, more style, more precision — all underpinned by German engineering rigor.



The Performance Upgrade: Nearly 800 Horsepower Without Breaking A Sweat


At the heart of the AC Schnitzer package for the G90/G99 is the performance upgrade, currently in preparation, which takes the standard hybrid drivetrain from 727 hp and bumps it to a staggering 799 hp. That’s not just a vanity metric — it places the tuned M5 squarely in the territory of supercars like the McLaren 765LT and beyond, while keeping all the creature comforts of a luxury sedan or estate. AC Schnitzer is also keen to emphasize that this bump in performance does not come at the expense of reliability. Their upgrade is designed to work harmoniously with the factory hybrid system and is backed by a comprehensive assembly warranty. This reassures customers that they’re not just bolting on power for the sake of numbers; they’re engineering an integrated solution that enhances the car without compromising its longevity or drivability. AC Schnitzer hasn’t yet published new torque or acceleration figures, but the base M5 already offers 737 lb-ft of torque and a 0–62 mph time of 3.5 seconds — so expect it to dip below 3.4 or even 3.3 seconds with the upgrade. The boost may “only” be 72 hp, but on an already potent platform, those extra horses can make a remarkable difference, especially at high speeds and during overtaking maneuvers.


Sporty Soundtrack And Sharpened Handling: Exhaust And Suspension


Performance is more than just numbers on paper — it’s about how a car feels, sounds, and responds. AC Schnitzer knows this and has crafted a stainless steel twin-exhaust system to give the M5 the voice it deserves. The new exhaust setup features two flaps and four ‘Carbon Sport’ tailpipes, each with an impressive 110mm diameter, arranged in pairs on each side of the rear. The result is an aggressive, characterful note that adds to the sense of occasion every time the throttle is pressed. Not only does it enhance the auditory experience, but it also sharpens the visual appeal of the rear end. Complementing the added muscle and sound is a specially tuned suspension spring kit. This reduces the car’s ride height by approximately 20mm compared to the standard setup, improving not just aesthetics but also driving dynamics. Lowering the center of gravity enhances steering precision, reduces body roll, and gives the driver a more connected and engaging experience — ideal for spirited driving on twisty roads or the occasional track day. The suspension isn’t so low or harsh as to compromise everyday comfort, staying true to AC Schnitzer’s philosophy of balanced enhancements.


Aerodynamic Refinement: Form And Function In Perfect Harmony



While power and handling are important, AC Schnitzer also turns its attention to aerodynamics, ensuring the M5 remains stable and composed at high speeds while sporting an even more assertive appearance. The aerodynamics package they’ve designed is extensive, incorporating functional elements that improve downforce and overall aerodynamic balance. At the front, a splitter and side wings work together to enhance grip and stability, particularly when cornering at speed. The sides benefit from redesigned skirts that not only visually lower the car but also contribute to airflow management. Depending on whether you choose the saloon or the Touring, the rear receives either a roof spoiler or wing, along with a three-piece rear diffuser and a rear spoiler, all working together to improve stability and reduce lift. Subtle yet effective design elements for the front fenders and protective foils for the side and rear skirts round out the package. To complete the look, customers can choose AC Schnitzer emblems in either silver or black, adding a final touch of personalization to an already bespoke appearance. Every element has been tested for both aesthetic and functional value, ensuring that nothing is merely decorative.


Forged With Precision: The Premiere Of AC6 Lightweight Wheels


A highlight of the AC Schnitzer program is the introduction of their new AC6 lightweight forged wheels, debuting on the M5. These wheels are as much a technical triumph as they are a visual statement. Featuring five Y-spokes that draw attention to the high-performance brakes behind them, the AC6 wheels give the M5 a more dynamic and aggressive presence. Available in two finishes — a bright natural aluminum with ceramic compaction and protective coating for a technical, deep look, or a glossy black for a more sinister aesthetic — these wheels are lightweight yet strong, optimizing unsprung mass and contributing to improved handling. They come in substantial sizes: 10.5J x 21 inches with 285/35 ZR21 tires up front, and 11.0J x 21 inches with 295/35 ZR21 tires at the rear. For drivers who wish to stick with the standard factory wheels but still want to improve the stance, AC Schnitzer also offers aluminum wheel spacers (7mm per side) to better fill out the wheel arches. The new wheels are a statement of intent — merging form and function to create a striking, race-inspired look while contributing to the overall performance envelope.


Interior Upgrades: Small Touches, Big Impact


While the bulk of AC Schnitzer’s efforts focus on performance and exterior styling, they haven’t ignored the interior. The company understands that drivers spend all their time inside the car, so they offer precision-machined aluminum components that enhance both feel and appearance. The package includes aluminum pedals, footrest, and a refined aluminum cover for the iDrive controller — elements that not only look more upscale but also feel more tactile and substantial compared to standard parts. An aluminum key holder rounds out the interior upgrades, providing a daily reminder of the car’s bespoke nature every time you pick up your keys. These subtle interior changes speak to AC Schnitzer’s attention to detail. They don’t overwhelm the cabin with unnecessary flash, but rather add meaningful, premium accents that enhance the sporty, luxurious atmosphere of the M5. It’s the kind of thoughtful touch that customers of this caliber expect — and receive — from AC Schnitzer.



The Philosophy: Motorsport DNA Brought To The Street


AC Schnitzer has always operated on the philosophy of bringing motorsport-inspired performance and style to road cars without overstepping into impractical extremes. The M5 G90/G99 program exemplifies this approach perfectly. Rather than simply chasing big numbers or ostentatious styling, every upgrade is carefully considered to ensure that it enhances the driving experience without sacrificing the inherent qualities that make the M5 such a revered vehicle. From the power bump to 799 hp to the functional aerodynamic components, and from the finely crafted forged wheels to the interior detailing, everything reflects AC Schnitzer’s ethos of harmony between sportiness, luxury, and usability. The package is clearly aimed at drivers who appreciate performance and style but still value reliability, warranty, and the ability to use their car daily. This balance is what makes AC Schnitzer stand out among tuning houses — they understand their audience and deliver accordingly.


Pricing And Availability: Patience Rewarded


At the time of writing in July 2025, the AC Schnitzer package for the M5 G90 and G99 is still under development, and final pricing details have not yet been announced. This gives potential customers time to consider their options and perhaps start saving — the base M5 saloon starts at approximately $144,000 (£111k) while the Touring version commands a small premium. Given the quality and comprehensiveness of AC Schnitzer’s work, the full upgrade package will likely carry a substantial price tag, though one that’s justified by the engineering, craftsmanship, and warranty included. Once fully available, customers will be able to select individual components or opt for a complete transformation, depending on their preferences and budget. Whether you’re interested in a subtle improvement or a full-on statement build, the AC Schnitzer program for the BMW M5 G90 and G99 promises to deliver.



Final Thoughts: The Ultimate Expression Of The M5


In an era where factory cars are already pushing the boundaries of what’s possible, it takes real expertise to enhance them meaningfully. AC Schnitzer has managed to do exactly that with the BMW M5 G90 and G99, crafting a package that’s more powerful, more poised, and more visually striking — yet still eminently drivable and reliable. The nearly 800-horsepower figure alone would be enough to grab headlines, but the real story here is the complete package: the aerodynamics that increase stability and style, the forged wheels that improve both form and function, the exhaust and suspension tweaks that enhance sound and handling, and the subtle interior details that remind you this is no ordinary M5. For drivers who want their M5 to stand out while still being perfectly suited to daily use, the AC Schnitzer program offers a compelling solution. It’s a thoughtful evolution of one of BMW’s most iconic models, and a testament to what happens when motorsport engineering and street sensibility meet. Whether in saloon or Touring guise, the AC Schnitzer M5 G90 and G99 promise to be not just a car you drive, but an experience you savor every time you hit the road.
