John Cooper Works GP
The third generation of the Mini John Cooper Works GP first appeared as a concept car in the IAA Cars 2017 with a track ready race-track character. The stripped-out interior included a roll cage and only a pair of racing seats (back seats were absent) with five-point racing harnesses. Outside, both front and rear wheels were covered by prominent wings (especially in the rear). A unique rear spoiler and centerlock 19" wheels were other features of the track-focused hot hatch. In June 2019, a tweet[62] was posted showing the Nürburgring time of 07:56:69 molded into the plastic trim of the dashboard.

The actual production model was revealed in November 2019, retaining some characteristics from the concept such as a very similar rear spoiler and wings (this time smaller in the rear). The wider track and wider wheels required wider wings. Other more extreme racing features (for a street car) like the centerlock wheels and five-point harnesses were removed, although the back seats were kept absent. The suspension is even stiffer and lower than a standard JCW and the turbocharger was redesigned for more boost pressure. The transmission is automatic only because there was no manual transmission available that could withstand the power and torque from the engine. The Nürburgring time on the dashboard was replaced by the individual production number (this same number appears on the front wings).

The 2.0 litre turbocharged engine outputs 225 kW (302 hp) and 450 N⋅m (332 lb⋅ft) of torque. The 0–100 km/h is 5.2 s and the top speed is 265 km/h (165 mph) (not cut off). As of release time, the third generation of the Mini JCW GP is the fastest and most powerful street car Mini has ever produced.

Production was limited to 3,000 units, with a MSRP of $44,900 (USD).

The third generation Mini was unveiled by BMW in November 2013, with sales starting in the first half of 2014. The new car is 98 mm longer, 44 mm wider, and 7 mm taller than the outgoing model, with a 28 mm longer wheelbase and increases in track width of +42 mm (front) and +34 mm (rear). The increase in size results in a larger interior and a boot volume increase to 211 litres.

Six all-new engines are offered for this Mini, four petrol and two diesels: two models of a 1.2 litre three-cylinder petrol with either 75 PS or 102 PS, a 1.5 litre 3-cylinder petrol with 136 PS, (BMW B38 engine), a 2.0 litre four-cylinder petrol (BMW B48 engine) that produces 192 PS for the Cooper S, and a 1.5 litre 3-cylinder diesel (BMW B37 engine) in two levels of power output: 95 PS and 116 PS (Cooper D), and a 2.0 litre turbo-diesel inline-four (BMW B47 engine) that produces 170 PS (Cooper SD). These engines are mated with a choice of either a 6-speed manual, a 6-speed automatic, or a 6-speed sports automatic gearbox.

MINI has also released an all-new model called the MINI 5-door (known as the 4-door in US, model code F55). It is marketed as a 5-door version of the new third generation Hatch. The base MINI 5-door is 6 in (152 mm) longer and 190 lb (86.2 kg) heavier than the 3-door MINI Hatch models, with similar performance characteristics and greater interior and cargo space. The 5-door is exclusively assembled at Plant Oxford with additional tooling for the body sides, new equipment in the wax sealing line in the plant’s paintshop to accommodate the extra door and differences in the shaping of the rear of the car. Plant Swindon produces the new rear door cells in the sub-assembly line with additional roof and panel tooling in the press shop.

The 3-door Mini with an automatic transmission will reach 0–97 km/h (0–60 mph) in 7.3 seconds for the 1.5L 3-cylinder petrol model and in 6.4 seconds with the 2.0L 4-cylinder petrol engine.

The Cooper S soon was joined by the higher performing John Cooper Works model in 2015.

In 2018, the Life Cycle Impulse (LCI), the 6-speed Steptronic torque-converter were replaced by a 7-speed dual-clutch transmission in all models but the Cooper SD and JCW, with the latter now fitted with an 8-speed Steptronic auto. These changes allow for improved efficiency and better emissions test results in the WLTP cycle, as well as marginally improved performance.

A battery-electric version, the Mini Electric (aka Cooper SE), was launched in 2020.

In 2021, the second Life Cycle Impulse (LCI) was released. The model received both optical and technical updates. The front and rear bumpers were redesigned, union jack taillights now came as standard as wel as LED headlights. The interior updates are limited to a new steeringwheel design and additional ambient lighting under dashboard trimpieces and in the doorcards.

On the technical side the petrol powered cars are fitted with a particle filter which led to a 10 horsepower decrease in power output for the B48 powered Cooper S.

Design
The shape is slightly more rounded than the one it replaces, in order both to improve the car's aerodynamic efficiency and to enhance pedestrian protection in the event of accidents. It has a much longer overhang and higher bonnet. This latest model rides on BMW's all new UKL platform that underpins the new BMW 2 Series Active Tourer.

Criticisms of the design of the F56 MINI Cooper have focused upon the extruded and complex design of the front bumper in Cooper S and JCW variants, as well as the larger front overhang and oversized tail lamps. Further criticism has also centred upon the overstyled nature of the exterior design.

The Mini is also the first in its segment to offer LED headlamps for its main and dipped beams as an option.

With its larger exterior dimensions, the all-new Mini provides more space for its four occupants and luggage, with enhanced shoulder space and larger footwells. Boot volume has been increased by more than 30% to 211 litres. When using only 2 seats in the car, boot capacity increases up to 731 litres.

The dashboard retains its instrument layout, but adds a new instrument binnacle on the steering column for the speedometer, tachometer, and fuel gauge. The central instrument display now houses a four-line TFT display with the option to upgrade to an 8.8 inch screen for navigation and infotainment functions.
