Manhart revealed its tuning package for the BMW M3 Cabrio. It is dubbed as the Manhart MH3 V8 R Biturbo and is equipped with an X5 /X6 M engine. Days ago, Manhart presented its modified BMW M5. The most significant change on the M3 Cabrio is the V8 4.4-liter twin-turbo engine of the X6 M with a carbon fiber cover.
Manhart optimized the software and modified the power unit to deliver 655 hp (488 KW) and 719 lb-ft (955 Nm) of torque.
By taking out the electronic top speed limiter, the modified M3 Cabrio can hit a top speed of over 199 mph (320 km/h). In addition, they also built an Akrapovic Evolution Titanium exhaust system with a sports catalytic converter and four 90mm tailpipes.
To manage this much power, the M3 is given X6 M-sourced 396mm drilled brake discs at the front and 374mm discs at the back with four-piston calipers.
It also gets the six-speed automatic transmission that originated from the X6 M and that was given a differential lock to offer improved traction. It rides on front 9x20 wheels with high-performance 255/35ZR20 tires and rear 12x20 alloys with 305/25ZR20 rubbers. The M3 Cabrio also got a MHR suspension system by KW with in-house changes.
With the efficient and smooth sharing of drive and steering forces on the rear and front axle, the suspension and chassis of the BMW M3 gives the best foundation for impressive performance and dynamic driving experience. The BMW M3’s chassis is certainly an innovative development that seeks to adjust effectively to the essential increase in power and to conserve weight on the process.
This is exactly the reason why most components of the brand new front axle are created from aluminum, which include the spring struts that are made stiffer than they were before, the central subframe, the swivel bearings, and the thrust plate that enhances the crosswise stability of the whole anterior section. It is true indeed that the BMW GmbH engineers were successful in saving excessive weight in the development of the superior brake system and its compound brake disks.
The BMW M3’s rear axle with five arms is also constructed following the brand’s advanced lightweight technology, with the sole exception of the single-track control arm. The special technology involved in the construction and design of all the aluminum arms, along with the aluminum dampers, also serve to decrease weight on this aspect of the car by as much as 5.5 pounds or 2.5 kilograms.
Anti-roll bars that were enhanced for their minimum weight and function are highlighted both rear and front. The modification in axle configuration in similar cases – featuring two more longitudinal bars, aside from the other modified or new components – provides improved kinematics that is developed for the car’s enhanced power and for its dynamic and athletic appearance.
