Manhart, the German tuning specialist best known for its high-performance BMW builds, has created some truly extreme vehicles over the years. Highlights include the 922-horsepower MH4 900, which transforms the BMW M4 CSL into a supercar-level machine, and the MH2 500, a BMW 2 Series–based model producing 502 horsepower. This time, however, Manhart has taken a more restrained approach with its latest project, the MHX6 500. Based on the BMW X6 xDrive40i, the aggressively styled fastback SUV produces 473 horsepower—an increase of 98 hp over stock—offering a noticeable performance upgrade without crossing into excessive territory.
A Bimmer With Balance
The power bump comes courtesy of Manhart Mhtronik chip tuner, which increases torque from 383 to 443 pound-feet. A valved exhaust system enhances the soundtrack, exiting through aggressive quad 3.9-inch tips. However, the catted downpipes are not TÜV-approved, meaning Manhart offers them for export markets only. Beyond that, mechanical upgrades remain relatively modest, underscoring the MHX6 500’s balanced approach. That said, Manhart is happy to tailor the build to individual preferences—while the SUV retains the standard BMW braking system, upgraded brakes are available upon request.
Customers can choose their preferred finish for the 22×10.5-inch front and 22×11.5-inch rear wheels, which fill the wheel arches more convincingly thanks to a slightly lowered stance achieved with revised suspension links. The Manhart body kit appears almost understated when paired with the BMW X6’s already aggressive factory design. Carbon fiber components—including the front lip, rear diffuser, and rear spoiler flap—are sourced from Larte Design. Inside, the MHX6 500 receives Manhart-branded steering wheel spokes, custom shift paddles, and a distinctive set of floor mats to complete the bespoke feel.
Making a Case for Moderation
While it might seem ironic to call a 480-hp, 4,900-pound SUV “understated,” the Manhart MHX6 500 is surprisingly balanced for a German tuner build. The SUV delivers plenty of power for spirited stoplight sprints, and the quad exhaust ensures it sounds as aggressive as it looks. Yet, unlike many heavily modified tuners, Manhart avoided over-lowering the suspension, preserving the BMW X6’s natural athleticism and ensuring the SUV handles its added horsepower with composure.
There’s an undeniable charm to the bold body modifications and Manhart decals on the MHX6 500. The SUV channels an almost Alpina-like approach, combining massive multispoke wheels and gilled front bumper extensions with a measured increase in power and performance. Other tuners have taken a similar route, such as the Brabus 800 XL Cabrio, which balances striking body modifications with tasteful cosmetic upgrades on the Mercedes G-Class.
If 473 horsepower isn’t enough, Manhart also offers a 720-hp version of the BMW X6 M. This extreme build features unique forged carbon body accents, ensuring the SUV is just as striking visually as it is on the road.
