What's the news?
BMW, using the opportunity of the space in the range created by the more expensive, more powerful M2 Coupe, has given its mid-ranking M Performance versions of the 1 Series and 2 Series a significant engine upgrade.
The 3.0-litre turbo six-cylinder engine now develops 340hp (up by 14hp) and 500Nm of torque. Both M140i and M240i have seen their acceleration figures drop by 0.3 seconds for 0-100km/h, with the M240i able to do that sprint in just 4.4 seconds if fitted with the optional eight-speed automatic gearbox. The M140i can do it in 4.6 seconds. That makes the M240i faster than the original 1 Series M Coupe.
Efficiency hasn't been sacrificed though - both models are claimed to be seven per cent more efficient than before, with the M240i recording 7.1 litres/100km on the combined cycle and CO2 emissions of 163g/km - both figures achieved when fitted with the automatic.
Four-wheel drive (branded 'xDrive') is optional on both models, although it does have an impact on fuel consumption, pushing the M240i xDrive to 7.8 litres/100km and 179g/km.
BMW is also introducing a new 2.0-litre turbo 184hp petrol four-cylinder engine for the 120i and 220i models. In a 120i five-door, that engine is good for a 7.1-second 0-100km/h time, 5.5 litres/100km fuel consumption and CO2 emissions of 126g/km (again, when fitted with the optional automatic gearbox).
The 125i and 225i models also get more power, increasing to 224hp. There will also be a new 252hp engine, but only available in the 230i Coupe and Convertible.
A new BMW Connected infotainment system is also being introduced across the manufacturer's ranges. Seen already on the 7 Series, the new setup has a menu layout arranged in tiles, better speech recognition (which can recognise simpler phrases), inductive smartphone charging and a WLAN Wi-Fi hotspot.
