John Cooper Works (JCW) is a British car marque now owned by BMW and it is an in-house tuning, development, and international automotive racing division for Mini vehicles.

In late July 2004, a vastly improved 210 package was launched that increased power further to 210 bhp (160 kW), with the following components:[4] A "JCW Sound Kit" (Cooper) was made available at the same time, consisting of the cat-back exhaust and the air filter, giving a sportier exhaust note and a 3 bhp (2.2 kW) power increase for around €1100.

The tuning kit includes a small plaque with a unique serial number mounted on the engine, as well as front and rear JCW emblems.

This new version comes with major differences from the factory, compared to the 192 bhp (143 kW) power kit that can be supplied through the dealer network: Commonly referred to as the GP2, the 2013 John Cooper Works GP is a limited-edition, track-oriented version of the regular John Cooper Works hatchback based loosely on the JCW Challenge race car.

The engine is essentially identical to the N18 used in other 2013 John Cooper Works models, with a slight increase in compression accounting for the modest power gain.

The GP2 also features exclusive 17” wheels, high-performance tires designed in a special partnership with Kumho, adjustable coil over suspension with revised geometry unique to the GP, 6-piston Brembo front calipers borrowed from the BMW 135i, a full valance tray and functional rear diffuser, a hatch-mounted spoiler with carbon fiber element, red mirror caps, brake ducts, signature badging, a pair of special-edition Recaro sport seats (complete with side-impact airbags), and deletion of the rear seats to save weight.

The stability control suite features an additional "GP mode" exclusive to this model which permits a greater degree of wheel-slip while retaining function of the brake-based electronic limited slip differential.
