2021 Manhart MH8 700 Cabriolet

710 horsepower and an aggressive look is what the M850i needed to make you forget about the M8

LISTEN 02:54

With 617 horsepower under the hood the M8 Convertible is a car many BMW fans dream about. However, the M8 Convertible is also an expensive car: prices start from $142,500 for the base version and from $155,500 for the competition one.

There is also the option to go with the M850i Convertible and pay $109,400. For the extra money, you can go to Manhart and ask for an upgrade. Its latest MH8 700 does just that: takes the M850i and transforms it into a mean looking car, with a lot more power than the M8.

What changes were made under the hood?

In order to squeeze more power, Manhart did some ECU remapping, made the turbochargers more powerful and added a new intercooler and sports air filters

In base form the BMW M850i Convertible is powered by a twin-turbo 4.4-liter V-8 engine that delivers a total of 523 horsepower and 553 pound-feet of torque. These are of course very good numbers for a luxury convertible, but as Manhart used us by now, there is always room for better.

It main focus was to increase the V-8’s output by as much as possible. The work started with some ECU remapping, making turbochargers more powerful and adding a new intercooler and sports air filters. Of course, the final touch was the addition of a new, stainless steel exhaust system with valve control and race downpipes without catalytic converter.

After all this work, the V-8 delivers a total of 710 horsepower and 682 pound-feet of torque.

There are no details on how the extra power will improve the car’s performance numbers, but we expect the MH8 700 Cabriolet to be a lot faster than the M850i Convertible. As a reminder, it goes from 0 to 60 mph in just 3.8 seconds and up to a top speed of 155 mph.

Are there any other changes?

It rides on a new set of 20-inch Manhart Concave One wheels wrapped in 245/35 and 275/30 high-performance tires

Yes! Not many, but Manhart did update both the exterior and the interior.

For the exterior, the MH8 700 receives new front and rear spoiler made out of carbon fiber and a new diffuser that will offer a more sporty look.

The black bodywork combined with the golden set of decorations complete the exterior look. Manhart actually has a similar approach with the recently launched MH3 600 package.

And a H&R lowering spring brings the car 30 mm (1.18 inches) closer to the ground

The MH8 700 Convertible rides on a new set of 20-inch Manhart Concave One wheels wrapped in 245/35 and 275/30 high-performance tires. The tuner opted t o keep the braking system, but went with calipers painted yellow to match the rest of the car. An H&R lowering spring brings the car 30 mm (1.18 inches) closer to the ground.

As for the interior, changes are limited to a steering wheel spoke and gearshift paddles made of carbon.
