The MINI John Cooper Works GP is another stunning example of the time-tested principle of taking the natural sporty DNA of the MINI to a new level by combining it with a whole string of features taken straight from the race track. With this elite sporting machine, the John Cooper Works brand, now a sub-brand of MINI, has raised the stakes yet again – the new model has shaved a whole 18 seconds off its predecessor’s best lap time during testing on the Nürburgring North Loop. This new best time reflects continuous advances in engineering, which have been tuned to the highest performance standards by John Cooper Works.
The astonishing torque gives the MINI John Cooper Works GP a 0 to 100 km/h (62 mph) time of 6.3 seconds. Mid-range acceleration is impressive too, with an 80 to 120 km/h (50–75 mph) time in fifth gear of just 5.9 seconds. Top speed is 242 km/h (150 mph). The turbocharged engine also delivers outstanding efficiency. This is further enhanced by MINIMALISM features which keep the average EU test cycle consumption of the MINI John Cooper Works GP down to 7.1 litres/100 km (39.8 mpg imp), corresponding to CO2 emissions of 165 grams per kilometre.
The MINI John Cooper Works GP’s exclusive suspension technology, too, relies heavily on motor sport. For the first time on a MINI, it features an individually adjustable coilover suspension, which allows ride height to be lowered by up to 20 millimetres. Among other things, this means the suspension set-up can be fine-tuned to different circuit conditions whenever the MINI goes out onto the track.
The front shock absorbers are mounted upside down in the tube, with the piston rod pointing down, in order to increase longitudinal and lateral stiffness.
The front camber has been increased compared with the regular MINI John Cooper Works, so that the performance potential of the sports tyres – which differ significantly from road tyres – can be used to full effect, without the penalties of early understeer, inevitably leading to increased tyre wear. Other features include reduced front-wheel toe-in and increased rear camber, which alters the forward weight transfer so as to give more speed and more neutral steering when driving close to the limit. At the same time, the reduced toe-in improves agility and cornering confidence.
Outstanding braking performance is provided by the MINI John Cooper Works GP’s racing-derived sports brake system, featuring six-piston fixed-calliper disc brakes, vented at the front. The front discs are 330 millimetres in diameter and 25 millimetres thick, with 280 x 10 mm discs at the rear. The low-weight 17-inch alloy wheels, again exclusive to the MINI John Cooper Works GP, run on high-traction 215/40 R17 sports tyres. Optionally, standard-size 205/45 R17 tyres are available on the same wheels, offering a good sporty balance between performance and good handling in wet or low-temperature conditions. The 7.5 x 17 H2 ET45 wheels, which were specially developed for the MINI John Cooper Works GP, are derived from the MINI Challenge race car, and feature lightweight contours on flow-formed rims.
