A few weeks after our initial encounter with the 2020 MINI John Cooper Works GP, our spies stumbled upon more prototypes of the manic hatch and managed to snap the first interior shots. The article and image gallery have been updated accordingly. (Updated 5/5/2019)

Mini is developing the range-topping John Cooper Works GP, a limited 300hp hot hatch version of the hatchback that will act as a swansong for the current model generation.

The 2020 Mini JCW GP will also be the company’s most powerful and fastest model yet, featuring a turbocharged 2.0-liter four-cylinder engine with more than 300hp. Production will be limited to just 3000 examples.

The ultimate Mini was previewed by the JCW GP concept back in 2017 and as such, it will feature a pretty wild body kit with plenty of aero enhancements.

The spotted prototype gets a rather simple wrap that practically gives away all the exterior details, including a dramatic roof spoiler and the extended fender flares that also act as aero elements.

Other exterior details include a deeper front spoiler, a different front grille and larger in diameter exhaust tips. The upcoming Mini JCW GP looks very aggressive to say the least, featuring a racecar-vibe that will probably split opinions.

Inside, what you see here isn’t the final product, but aside from the sporty seats, which will likely be replaced by even more aggressively bolstered units, the rev-counter ahead of the driver has been replaced by a screen with rounded corners. This isn’t the first time we’ve seen this solution, as prototypes of the electric Cooper S E also featured the same setting.

Another revelation from these latest spy shots is the use of an automatic transmission, though being that MINI has not yet said what gearboxes will be on offer, we don’t know whether it will be the sole choice or if a 6-speed manual will also be available.

The new 2020 Mini JCW GP will feature wider tracks front and rear, along with a revamped suspension, bigger brakes and stickier tires. Mini may also use lightweight materials, like carbon fiber, and ditch the rear bench seat completely in order to further reduce weight.

Mini has already teased the new JCW GP by releasing a pair of images last February. With test cars now out in public roads wearing so little camo, it’s probably safe to assume that the reveal time approaches fast. Sales of the new Mini JCW GP are expected to begin in late 2019.
