What is it?
It’s a 1-series with three doors and, at the same time as it’s introduced to the UK (May 2007), a range of improvements will also be made to the five-door 1-series. So it’s a mid-life facelift, really.
What’s it like?
We’ve always appreciated the 1-series for the way it drives, if not its lack of roominess. So at a stroke, having only three doors seems to enhance and amplify the dynamic appeal of the 1-series, suggesting that driving, not practicality, is the high point on the agenda. Which, granted, is a slightly superficial way of looking at it, but it works for us.
Underneath though, the 1-series three-door is the same as the five-door. The facelift includes new headlight surrounds and a more pronounced spoiler, but when I tell you that BMW says ‘certainly not least’ of the changes are different-shaped front foglights, you’ll get an idea of how minor the exterior alterations are. There are new materials in the (still undersized) interior, too.
Mechanically this is a traditional BMW-type upgrade – improve a hundred things by one per cent, rather than one thing by 100 per cent. The biggest change is the adoption of latest-generation direct injection for the petrol engines – it makes a heck of a difference to economy and power.
Take the 2.0-litre petrol, which is the only new 1-series we’ve tried to date (late Feb ’07). It develops 20bhp more than before (now 168bhp) and 7lb.ft extra (155lb ft). So it’s nearly a full second quicker to 62mph from rest (now 7.7sec). No slouch, but the 120i has little chance of keeping up with more powerful hot hatchbacks at the same price.
It’s still enjoyable to drive though. Less agile than the best hot hatchbacks, but there’s a reassuring stability and balance to the way a 1-series goes down the road. Its ride, on the averagely-surfaced roads we’ve driven, is pretty reasonable (bigger-wheeled models are typically a 1-series’ undoing), body movements are ably controlled and its steering is accurate and responsive.
Economy is also improved. As well as the new injection system, four-pot 1-series get brake energy regeneration to charge the battery (the alternator doesn’t charge full-time), and a Stop/Start system in traffic. It isn’t an option - if you buy a facelifted 120i, you get the Stop/Start function. And it works. Combined fuel economy has risen from 37.7mpg (with 181g/km of CO2 emissions) to 44.1mpg (and just 152g/km). Which is pretty impressive.
