2016 BMW 1-Series 3-door: five new diesel engines

2016 BMW 1-Series 3-door diesel

 The new BMW 1-Series model range has been given an almost totally updated line-up of diesel engines. Both the new-generation three-cylinder and latest four-cylinder engines are based on the same efficiency-optimised underlying concept and boast new turbocharging technology and further developed common rail direct injection systems. Variable turbine geometry and turbocharger shaft guidance which, depending on the engine variant, involves a slide bearing or roller bearing, optimise the engines' responses, while new solenoid valve injectors generating injection pressure of up to 2,500 bar increase the precision of the fuel metering process. Furthermore, advances have been made with the new diesel engines in terms of acoustic comfort as well as thermodynamics, power development and efficiency.

The output spectrum of the diesel engines has been expanded and now ranges from 85 kW/116 hp to a new peak of 165 kW/224 hp. Reductions in fuel consumption of up to 12 percent have been achieved (depending on the model variant). All the diesel models in the new BMW 1-Series line-up have CO2 emissions of under 120 grams per kilometre.

The 1.5-litre three-cylinder engine under the bonnet of the new BMW 116d generates maximum output of 85 kW/116 hp and 270 Newton metres (199 lb-ft) of torque - up 10 Nm (7 lb-ft) on its predecessor. The new BMW 116d takes 10.3 seconds to accelerate from 0 to 100 km/h (62 mph), both with the standard six-speed manual gearbox and with the optional eightspeed Steptronic transmission. The fuel consumption and CO2 emissions of the new BMW 116d are 4.1 - 3.7 litres per 100 kilometres [68.9 - 76.4 mpg imp] (automatic: 4.1 - 3.6 [68.9 - 78.5 mpg imp]) and 107 - 97 (107 - 96) grams per kilometre (figures according to EU test cycle, may vary depending on the tyre format specified).

The new BMW 116d EfficientDynamics Edition takes to the stage with further reductions in fuel consumption and emissions up its sleeve. This variant uses features such as a switchable coolant pump and specific combustion chamber pressure control for its likewise 85 kW/116 hp three-cylinder diesel engine to set a new efficiency benchmark for the whole of the BMW model range. The new BMW 116d EfficientDynamics Edition accelerates from 0 to 100 km/h (62 mph) in 10.4 seconds and posts average fuel consumption of 3.8 - 3.4 litres per 100 kilometres (74.3 - 83.1 mpg imp). CO2 emissions are 101 - 89 grams per kilometre (figures according to EU test cycle, may vary depending on the tyre format specified).

The new four-cylinder diesel engine for the BMW 1-Series is offered at three output levels. The 2.0-litre units have overhead valves and overhead camshafts and differ from one another primarily on account of their turbocharging technology. In the new BMW 118d the power unit develops maximum output of 110 kW/150 hp and peak torque of 320 Newton metres (236 lb-ft), enabling acceleration of 0 to 100 km/h (62 mph) in 8.3 (automatic: 8.1) seconds. Its average fuel consumption stands at 4.3 - 4.0 litres per 100 kilometres [65.7 - 70.6 mpg imp] (automatic: 4.2 - 3.8 litres [67.3 - 74.3 mpg imp]), while CO2 emissions are 114 - 104 (110 - 99) grams per kilometre.

The 140 kW/190 hp version of the new four-cylinder diesel unit serves up peak torque of 400 Newton metres (295 lb-ft) and whisks the new BMW 120d from 0 to 100 km/h (62 mph) in 7.1 (automatic: 7.0) seconds. The sporting instincts of this model variant combine with average fuel consumption of 4.5 - 4.1 litres [62.8 - 68.9 mpg imp] (automatic: 4.3 - 3.9 litres [65.7 - 72.4 mpg imp]) per 100 kilometres and CO2 emissions of 118 - 108 (114 - 103) grams per kilometre (figures according to EU test cycle, may vary depending on the tyre format specified).

The most powerful four-cylinder diesel engine gets to work in the new BMW 125d. It features multi-stage turbocharging with variable turbine geometry for the high-pressure charger, making for instantaneous responses at the slightest touch of the accelerator along with an impressive power curve across a broad rev range. Ensuring particularly precise fuel metering is the new version of common rail direct injection which operates at 2,500 bar. Output of 165 kW/224 hp and peak torque of 450 Newton metres (332 lb-ft) propel the 125d - which is fitted as standard with the eight-speed Steptronic transmission - from rest to 100 km/h (62 mph) in 6.3 seconds. Its performance is also class-leading in terms of average fuel consumption and CO2 emissions. The key figures here are 4.6 -4.3 litres per 100 kilometres (62.8 - 65.7 mpg imp) and 121 to 114 grams per kilometre (figures according to EU test cycle, may vary depending on the tyre format specified).
