BMW will launch a new range of engines for the five-door BMW 1-series from March. These include a new four-cylinder petrol unit that slots into the 125i and two new diesels, which will be used in the 125d and 116d Efficient Dynamics.
BMW’s new 2.0-litre TwinPower turbo four-pot produces 218bhp at 5000rpm and 229lb ft of torque available between 1350 and 4800rpm. On the combined cycle, BMW claims 42.8mpg with 154g/km Co2 emissions. This sits the car in road tax band G, which costs £165 per year.
The revised 2.0-litre diesel engine for the 125d (which replaces the 123d) also produces 218bhp, making it 13bhp and 50lb ft more powerful than its predecessor. The sprint to 62mph is dispatched in 6.5sec and flat out, the 125d will hit 149mph. When mated to BMW’s 8-speed automatic gearbox, the car will achieve 58.9mpg and 126g/km Co2, which will set you back £95 in road tax.
BMW’s most frugal new offering to the line-up – the 116d EfficientDynamics – delivers 116bhp at 4000rpm and 192lb ft of torque between 1750 and 2500rpm. Fitted with a six-speed manual ‘box, the 116d ED undercuts the crucial 100g/km Co2 marker (at 99g/km), while realising up to 74mpg. The road tax-exempt and London Congestion Charge-free 116d ED has a top speed of 121mph, with 62mph from standing reached in 10.5sec.
On top of its new engine line-up, BMW has also launched its Blue Performance tech for the 120d. Thanks to an additional nitrogen oxide (NOX) catalyst storage, the 120d Blue Performance already meets the EU6 emissions standard, which takes effect in 2014.
From March, the five-door 1-series will be available in M Sports trim. Features include a 10mm lower ride height, revised spring and shock absorber rates and beefier anti-roll bars. An M Sports break pack comes as an option (excluding 125i and 125d models) and comprises aluminium multi-piston-fixed calipers finished in dark blue metallic and larger lightweight brake discs.
