The newcomer has more presence than its predecessor, thanks to its substantially large headlamps that fade into the front wheelarches, a more prominent radiator grille, and compact lower air intakes. With an increased length and width of 4,320mm (+85mm) and 1,770mm (+17mm), a longer wheelbase of 2,690mm (+30mm over the outgoing model) means the cabin is more spacious and luggage capacity increases to 360 litres (+30 litres) behind the rear seats. With the rear seats folded, you will have 1,200 litres at your disposal.
Internally, there's an improved dashboard design and higher quality materials has been used. A 6.5” iDrive display (8.8” will be optional) will be standard with the 8-speed automatic. Standard equipment will include air-conditioning, remote central locking w/engine stop-start button, multi-function leather steering wheel, USB port w/Bluetooth, and 16” alloy wheels. On the options list, live Internet, satellite navigation system, bi-xenon headlights, auto-dimming door mirrors, Nappa leather upholstery, heated front seats, wood décor, heated steering wheel, alloy wheels, and upgraded sound systems will be offered.
Like the current model, a host of petrol and diesel engines will be available. Firstly on the petrol side, a 1.6 turbocharged unit will come in many tunes, starting with the entry-level 116i that produces 134bhp (132PS/100kW) and 220Nm (162lb-ft) of torque, followed by the 118i with 170bhp (168PS/127kW) and 249Nm (184ft-lb), before topping out on the 120i that squeezes out 247bhp (250PS/184kW).
On the diesel front, power comes from a turbocharged 2.0d that will develop either 114bhp (116PS/85kW) and 260Nm (192lb-ft) of torque, 141bhp (143PS/105kW) and 320Nm (236lb-ft), and a 181bhp (184PS/135kW) with 380Nm (280ft-lb). These will be named 116d, 118d, and 120d when they go on sale, alongside an Efficient Dynamic model that will expel 99g/km and return 74.3mpg (3.8l/100km) from its 116bhp (114PS/87kW) 1.6 litre diesel. Both 6 speed manual and 8 speed automatic will be standard across the range.
With BMW's EfficientDynamics fitted as standard, all models will come with a stop/start system, and regenerative brakes. That means average fuel economy will linger between of 48.7mpg – 65.7mpg (5.8l/100km – 4.3l/100km).
