The 2015 BMW 1 Series range has been given a mild facelift, with the line-up will be going on sale in the UK in the spring. The model has been displayed at the Geneva motor show.
What is it?
For this mid-life face-lift, BMW has given the 1 Series revised front and rear styling, upgrades to its infotainment system and options list, and most important, a new range of three-cylinder diesel engines and revised four-cylinder units that promise more power but greater efficiency.
What engines can I choose from?
The diesel engines are all from the same family of motors that has just appeared in the latest Mini, although since they're being fitted to the rear-wheel-drive 1 Series, they've been turned 90 degrees into a longitudinal layout. The entry-level model will be the 116d, which gets a three-cylinder 1.5-litre unit producing 114bhp and emitting as little as 94g/km with the standard six-speed manual gearbox, depending on tyre sizes.
A new version of ZF's eight-speed automatic transmission will be offered across the range, and its revised hardware and software helps to improve efficiency further; the 116d auto emits 96g/km of CO2. There will also be a manual gearbox-only 116d Efficient Dynamics, which uses a switchable coolant pump and combustion chamber pressure control to lower its CO2 emissions to as little as 89g/km.
There are also three 2.0-litre diesels, badged 118d (148bhp and 110g/km to 99g/km), 120d (188bhp and 118g/km to 109g/km) and 125d (221bhp and 121g/km). The first two of this trio will be offered with xDrive four-wheel drive, too, although the 118d xDrive will be restricted to a manual gearbox and the 120d xDrive is available only with the eight-speed auto.
The M135i gets the same powertrain as the M235i, with a turbocharged 3.0-litre six-cylinder engine producing 322bhp and 332lb ft. That's enough to take it from 0-62mph in 5.1 seconds - or 4.9 seconds if you choose the automatic.
The 118i will be the entry-level petrol engine in the UK, with 134bhp and CO2 emissions of between 134g/km and 125g/km, depending on your choice of gearbox and wheel size.
The 120i is the mainstream choice, with 174bhp and 184lb ft, and a 0-62mph time of 7.4 seconds (or 7.2sec with the eight-speed auto). Its CO2 emissions range from 136g/km to 133g/km. There's also the 125i, with 215bhp and 228lb ft; it cracks 0-62mph in 6.4sec and returns CO2 emissions of 154g/km - or 148g/km with the auto 'box.
How much equipment does it come with?
The 1 Series' cabin gets more modest upgrades, including a piano-black finish to the centre console on all trim levels, chrome highlights on the radio and air vents and, in a throwback to BMWs of old, an analogue real-time fuel consumption gauge on models without a digital instrument panel.
All 1 Series will now get single-zone climate control as standard, with the option of a dual-zone system, and the infotainment system has also been revised. Even the entry-level Business stereo gets a power and torque display, while the range-topping Professional system can update its map data remotely by using its built-in SIM card. Several optional features have been improved too; for example, the self-park facility can now park the car into a car park space as well as completing a parallel manoeuvre in a street.
How much does it cost?
Although the full pricing has yet to be revealed, BMW has confirmed that the three-door 118i SE starts at £20,245, while the five door version starts at £20,775.
Anything else I need to know?
The front-end styling revisions were actually forced by the revised engines, some of which require greater cooling than before. The air intakes are larger as a result and BMW used this modification as an opportunity to alter the shape of the headlights, too; they're now more rectangular than before, with space for revised lens units.
The specs of the lights themselves will change too; even entry-level cars will get daytime running lights as standard, while the old optional xenon units have been dropped in favour of full LED set-ups. M Sport editions of the car will get LED headlights as standard.
The tail-lights are now more in line with BMW's family style, thanks to a shallower main unit and distinctive 'blades' that run in from the edges of the rear hatch itself. They're also get LED technology as standard across the range.
