2015 Maxi-Tuner MINI John Cooper Works F56 Side ViewMaxi-Tuner MINI John Cooper Works is literally a supermini. It stands out with new exterior appearance and more power than ever. Based on the most powerful production MINI, the F56, this modified JCW has added numerous visual and performance upgrades. The package comprises of ‘MaxPower' and ‘MaxSound' kits and other additions to the exterior… but let's see what has really happened here.

Exterior

The appearance of the Maxi-Tuner MINI John Cooper Works stands out due to some extra visual goodies. The car stands out as an extrovert due to its new front bumper with huge air intakes. The tuner also added sculpted side sills for more athletic appearance. At the rear we see a diffuser that frames its dual exhaust outlets.

Engine Uprated with MaxPower

The production version of the JCW F56 is powered by a 2.0-liter four-cylinder turbocharged engine, which is 231 hp (170 kW) and 320 Nm (236 lb-ft) strong.

Thanks to the in-house made MaxPower plug and play auxiliary ECU with bespoke wiring harness, Maxi-Tuner achieved a power boost of 260 hp (191 kW) and a peak torque increase of up to 390 Nm (288 lb-ft). This is an addition of 29 hp and 70 Nm.

The bigger output also results in crisper e-gas throttle response, better driving dynamics and faster acceleration against the stopwatch. However, the intelligent control electronics in the MaxPower box do not change the factory diagnostic and service functions.

This means that the engine temperature reaches the factory limits, the system reverts to standard parameters, retarding the ignition to reduce power.

MaxSound

Maxi-Tuner MINI John Cooper Works is also fitted with custom MaxSound sport exhaust system. This one contributes to a louder voice to match the enhanced performance. It is made from high quality stainless steel and features sport exhaust features 70 mm tube diameters and a remote control for the flap system. At last, Maxi-Tuner left both tailpipes operating despite of the flap position.
