BMW 1 Series three-door

BMW has released the first pictures and details of the new three-door 1 Series. It's available to order now, with first deliveries due in September.

The three-door 1 Series is the same length, width and height as the five-door 1 Series, which went on sale last year. It is 85mm longer than the model it replaces, with a 30mm longer wheelbase and wider front and rear tracks meaning more cabin space.

It is available as a four or five-seater, while boot space has been increased by 30 litres to 360, or 1,200 litres with the rear seats folded.

The five-door's engine line-up has been carried over but there's a new entry-level 114i and a range-topping M135i.

The 114i is powered by a 1.6-litre four-cylinder petrol engine, which develops 101bhp, returns 49.6mpg and emits 132g/km of CO2. Next up is the 116i, which gets a 134bhp 2.0-litre turbocharged petrol engine and returns 51mpg and 129g/km of CO2. The 125i uses the same 2.0-litre engine, tuned to produce 215bhp.

The flagship M135i model uses a 315bhp 3.0-litre turbocharged six-cylinder. It can go from 0-62mph in 5.1 seconds, and returns 35.3mpg and 188g/km of CO2.

The diesel range is made up of a 116d, 118d and 125d. There are two versions of the 116d - both are powered by a 114bhp 2.0-litre four-cylinder turbo, but the EfficientDynamics version is the most economical with 74.3mpg and tax-free emissions of 99g/km thanks to gearing and aerodynamic tweaks.

The range-topping diesel is only available in M Sport trim, and gets 215bhp, a 0-62mph time of 6.5 seconds and returns 57.6mpg and 129g/km of CO2.

Each comes fitted with a six-speed manual gearbox as standard, but an eight-speed automatic is available.

It's available in five trim levels: ES, SE, Sport, Urban and M Sport. Entry-level models come with keyless start, 16-inch alloy wheels, ABS and ESP. SE adds a 6.5-inch display, a multi-function steering wheel, plus USB and bluetooth connectivity, while Sport models get 17-inch alloy wheels, sportier bumpers, sport seats and a sport steering wheel with red stitching.

Urban models 17-inch alloys, half-leather upholstery and a bespoke grille with white inserts. M Sport cars come with sportier bumpers, an aero kit, 18-inch alloys, sport seats and a bespoke suspension set-up. The range-topping M135i gets an M Sport braking, steering and suspension system.

BMW has also confirmed its all-wheel drive system, branded 'xDrive', will be fitted to the 1 Series in some European markets, but these versions have not yet been confirmed for the UK market but may join the line-up in the future. 

Prices for the new three-door BMW 1 Series range from £17,300 to £29,995.
