BMW has released details of its second-generation 1 Series, with revised engines, a more striking design and improved technology.
The most obvious styling changes are at the front, with the large BMW 'kidney-shaped' grille, bigger headlamps and a three-section air intake. At the back, larger tail lamps are the main feature.
The new 1 Series is also 83mm longer, 14mm wider and 30mm longer than the outgoing model, so there's more cabin space. That's good news for rear occupants, who now get 21mm extra legroom. There's also a bigger boot, increased by 30 litres to 360 litres.
Reduced CO2 emissions and improved economy are also key. This is helped with Auto Start Stop technology, now standard in manual and automatic versions - the latter armed with eight speeds.
Next year BMW will launch a 116d EfficientDynamics capable of 74.3mpg while emitting just 99g/km of CO2 - making it exempt from road tax. BMW's ECO PRO system is standard which automatically adjusts throttle response to encourage a more economical driving style.
In the meantime, the line-up comprises of revised versions of existing engines which are now quicker and more eco-friendly.
The biggest changes affect the two versions of the 1.6-litre twin-turbo petrol, badged 116 and 118i. The 116i now has 136bhp, making it good for 0-62mph in 8.5 seconds, while averaging just under 50mpg. Emissions have also dropped from 143g/km to 129g/km.
The 118i is now 29bhp more powerful and takes a spritely 7.4 seconds to reach 60mph from standstill. CO2 emissions have been reduced to 134g/km.
Economy and power for the diesels have been improved too, with the new 116d the most frugal, returning an impressive 62.8mpg, and CO2 emissions of 117g/km. The improvements from the remaining versions - the 118d and 120d, are fairly slight.
The facelifted BMW 1 Series is set to go on sale in September with prices starting at £19,375, with a three-door version, and more powerful derivatives also due in 2012.
