Five doors and a new basic engine type now make entry into the world of Mini more convenient and highly economical at the same time. As of March 2015, the model program of the latest generation of small cars will be expanded to include the Mini One First 5 door. As for the new Mini 3 door, this means that the five-door body variant will also offer a range of seven engine types to choose from.

The Mini One First 5 door is powered by a completely newly conceived engine featuring Mini TwinPower Turbo Technology. Its 1.2 3-cylinder spark ignition engine combines turbocharging with petrol direct injection and variable camshaft control on the intake and exhaust side (double VANOS). It generates a peak output of 55 kW/75 hp and a maximum torque of 150 Newton metres which goes on stream at 1,400 rpm, accelerating the new Mini One First 5 door from zero to 100 km/h in 13.4 seconds.

Power transmission to the front wheels is taken care of by a likewise newly developed 6-speed manual transmission offering optimised efficiency, reduced weight and a high level of shift comfort. Also, an integrated gear sensor enables smooth and dynamic shifting. The high efficiency of the new drive technology is reflected in an average fuel consumption of 5.2 litres per 100 kilometres. The relevant CO₂ emission level of the new Mini One First 5 door is 121 grams per kilometre (EU test cycle figures, dependent on tyre format selected).

The market launch of the new basic model expands the engine portfolio of the Mini 5 door (combined fuel consumption: 5.9 - 3.5 l/100 km, combined CO₂ emissions: 136 – 92 g/km) to four petrol and three diesel engines, covering an output range of 55 kW/75 hp to 141 kW/192 hp. Apart from the extra doors, the car also features a wheelbase which has been extended by 72 millimetres as compared to the new MINI 3 door. With its three seats at the rear and a luggage compartment which can be expanded from 278 to 941 litres as needed, the brand's first five-door model is targeted to attract new groups in the small car segment.
