Manhart GP3 F350 takes 2020 Mini JCW GP to 345bhp

The new Mini JCW GP hasn’t been with us for long, but Manhart has already worked its magic

Deliveries of the 2020 Mini JCW GP have only just begun, but Wuppertal-based Manhart Performance has already devised a tuning package for the brand’s fastest model yet. Further options are in the pipeline, but for now the current performance kit will set you back €3850 (approx £3500).

Manhart Performance isn’t short of experience on BMW products, making the GP’s B48 2-litre four-pot an easy target for tuning. The ‘MHtronik Powerbox’ is combined with a new Airtec intercooler for a 43bhp, 59lb ft bump in power – this brings the total to 345bhp and 391lb ft of torque, not far from the output of AMG’s non-S A45.

This power is sent to the front wheels through an eight-speed automatic gearbox, and although new performance figures haven’t been disclosed, it's safe to assume that you’ll see a mild improvement on the standard 5.2sec 0-62mph time and 146mph top speed. If you’d like the remap alone, it will set you back €1001 (approx £900).

To enhance sound, you can opt for a Remus stainless steel cat-back exhaust system, complete with valve control to help you maintain a healthy relationship with your neighbours. You can also bypass the gasoline particulate filter with the use of a replacement pipe, and have the choice of no catalytic converters or less-restrictive 200-cell sport items. The valve-controlled system is priced at €1725 (approx. £1500), and can be completed with either carbonfibre or ceramic exhaust tips.

As if the design of the new Mini GP wasn’t extreme enough, Netherlands-based JDCustoms can add its touch, applying a matt black wrap and a handful of gold accents. This option doesn’t come cheap, though, at €3411 (approx. £3100). To match, you can also opt for gold detailing on the new 19-inch Manhart Concave One wheels.

Lifting those new wheels into the arches are lowering springs from AST Suspension, dropping ride height by 20mm at the front and 15mm at the rear, with a full coilover kit currently under development. Also in the pipeline is an improved exhaust system, further engine power upgrades and more.

Manhart will also provide new digital interior gauges should you desire, alongside some additional interior Alcantara, including a retrimmed steering wheel.
