BMW M Performance Automobiles in the BMW 1 Series and BMW 2 Series model ranges are to showcase their sporting character with even greater style.
The new six-cylinder in-line petrol engine in question –develops 250 kW/340 hp, and now with an 10 kW/14 hp increase in maximum output over its predecessor – not only optimises the sprinting power of the two cars, it also lowers their fuel consumption and CO2 emissions.
The 3.0-litre unit with further developed M Performance TwinPower Turbo technology is a product of the BMW Group’s latest engine generation.
The advances in dynamics and efficiency that come as part of the package are also expressed by the new model designations for the BMW M140i 3-door, BMW M140i 5-door, BMW M240i Coupe and the BMW M240i Convertible.
This boost in power means the BMW M Performance members of the BMW 1 Series and BMW 2 Series model ranges now offer the same output levels as the BMW 1 Series M Coupe built between 2011 and 2012.
They can accelerate from 0 to 100 km/h (62 mph) up to 0.3 seconds quicker than their predecessors, and their fuel consumption and emissions are as much as 7 per cent lower.
The BMW M140i 3-door, BMW M140i 5-door, BMW M240i Coupe and BMW M240i Convertible are fitted with a six-speed manual gearbox as standard, while the latest version of the eight-speed Steptronic Sport transmission is available as an option.
As an alternative to sending their power to the rear wheels, all four models can also be ordered with BMW xDrive intelligent all-wheel drive.
A key element in the new engine’s ability to serve up thrillingly dynamic acceleration is the pulling power that comes on tap early and is maintained over a wide rev range. The new unit lays on peak torque of 500 Newton metres (369 lb-ft) between 1,500 and 4,500 rpm and generates maximum output of 250 kW/340 hp at 5,500 rpm.
The latest-generation six-cylinder in-line engine can be combined with the likewise new version of the eight-speed Steptronic Sport transmission as an option. With its wider gear spread and further improved internal efficiency, this automatic transmission – fitted as standard on the all-wheel-drive versions of the compact BMW M Performance Automobiles – makes an additional contribution to increasing efficiency.
The extra dynamic power by the further developed powertrain technology is reflected by significantly improved acceleration values. The BMW M140i 3-door and BMW M140i 5-door complete the dash from 0 to 100 km/h (62 mph) in 4.8 seconds with the standard six-speed manual gearbox, or 4.6 seconds with the optional eight-speed Steptronic Sport transmission.
All of which means they reach 100 km/h (62 mph) 0.3 seconds sooner in both cases than their respective predecessors.
An identical improvement can be seen with the BMW M140i xDrive 3-door and BMW M140i xDrive 5-door, which dispatch the same sprint in just 4.4 seconds. Average fuel consumption in the EU test cycle comes in at 7.8 litres per 100 kilometres for the BMW M140i 3-door and BMW M140i 5-door and 7.4 litres per 100 kilometres for the BMW M140i xDrive 3-door and BMW M140i xDrive 5-door. This therefore equates to a drop of between 3 and 5 per cent below the figures recorded by the outgoing models. CO2 emissions are now 179 grams per kilometre for the rear-wheel-drive models and 169 grams per kilometre where xDrive is involved.
The BMW M240i Coupe likewise powers from 0 to 100 km/h (62 mph) in 4.8 seconds or 4.4 seconds in all-wheel-drive guise. Those figures represent an improvement of 0.2 seconds in both cases. Fuel consumption and emissions in the EU test cycle are down by 4 to 7 per cent compared to their predecessors’ values. The BMW M240i Coupe now posts a figure of 7.8 litres per 100 kilometres [36.2 mpg imp] (179 g/km) with the manual gearbox or 7.1 litres per 100 kilometres [39.8 mpg imp] (163 g/km) when the eight-speed Steptronic Sport transmission is fitted. The BMW M240i xDrive Coupe is rated at 7.4 litres per 100 kilometres [38.2 mpg imp] (169 g/km).
Both variants of the open-top BMW M Performance Automobile race from rest to 100 km/h (62 mph) 0.3 seconds faster than before. The acceleration figures now stand at 4.9 seconds for the BMW M240i Convertible and 4.6 seconds for the BMW M240i xDrive Convertible.
Combined fuel consumption and emissions in the EU test cycle drop by 2 to 6 per cent – to 8.3 litres per 100 kilometres in conjunction with the six-speed-manual gearbox, 7.4 litres per 100 kilometres if the eight-speed Steptronic Sport transmission is fitted, and 7.8 litres per 100 kilometres in the case of the BMW M240i xDrive Convertible.
