The revised BMW 1 Series range is here, with the eco-champion being the 116d EfficientDynamics Plus model with 83.1mpg and 89g/km CO2.
The revised model has new power units, additional EfficientDynamics technologies fitted as standard, and thankfully new front end styling.
The new BMW 1 Series will, from September production onwards, come as standard with navigation. In the meantime other models within the BMW range will also gain this high level of equipment and functionality and this will mean by September the entire BMW range will have navigation as standard. BMW is the first automotive manufacturer to offer cars from the compact segment all the way through to large luxury vehicles with navigation fitted.
The new BMW 1 Series sees the introduction of powerplants from the BMW Group’s new engine family, plus an expansion of the standard-fit BMW EfficientDynamics technology.
The new engines bring a reduction in fuel consumption of up to 12 per cent while simultaneously providing more power and sharper responses. All engines meet the Euro 6 exhaust emissions standard and offer as much as 326hp in the new M135i, with CO2 emissions as low as 89g/km in the new 116d EfficientDynamics Plus model. The eight-speed Steptronic transmission has been further refined.
One of our favourites, the five-door 125d, has 224hp, 450Nm of torque, a 0-62mph time of 6.3 seconds, a combined economy figure of 61.4mpg and 121g/km CO2, and costs £30,330.
Another favourite is the 325hp M135i – it’s one of the best driver’s cars that you can buy, and it still returns 37.7mpg – and it only costs a fraction more than the 125d at £31,200.
All of the BMW 1 Series diesel engines are sourced from the BMW Group’s new engine family.
The BMW 118i and BMW 120i are both powered by a 1.6-litre four-cylinder engine. It develops 136hp and 170hp respectively, offering acceleration as low as 7.2 seconds to 62mph in the 120i and with fuel consumption and CO2 emissions of just 52.3mpg and 125g/km in the 118i. The four-cylinder engine in the 125i features a 2.0-litre displacement, providing 218hp and peak torque of 310Nm, enabling a 0-62mph time of just 6.2 seconds.
At the top of the petrol engine range remains the M135i with its turbocharged straight-six engine. Power has been increased in the new model to 326hp, with peak torque of 450Nm, enabling a 0-62mph time of just 4.9 seconds, yet the ability to return 37.7mpg.
The 1.5-litre three-cylinder engine in the new BMW 116d generates 116hp and 270Nm of torque, an increase of 10Nm compared to its predecessor. The standout figures for the new model are a 0-62mph time of 10.3 seconds coupled to fuel consumption as little as 78.5mpg and CO2 emissions of 94g/km. These efficiency figures can be improved yet further with the 116d EfficientDynamics Plus model which, via a range of measures, attains 83.1mpg with CO2 emissions of just 89g/km.
The new four-cylinder diesel engine used in the latest BMW 1 Series is offered in three states of tune: the 118d generates 150hp and 330Nm of torque, the 120d has 190hp and 400Nm, and the 125d, with its multi-stage turbocharging, provides 224hp with 450Nm of torque, enabling this model to reach 62mph from rest in just 6.3 seconds. The 118d can achieve a fuel consumption figure of just 74.3mpg, but even the 125d manages 61.4mpg.
The majority of new BMW 1 Series variants are fitted with a six-speed manual gearbox as standard, offering engagement speed control for the smoothest possible gearchanges. However, the 120d xDrive all feature as standard the eight-speed Steptronic gearbox otherwise available as an option. This automatic transmission has improved internal efficiency, longer gear ratios, optimised transmission management and a vibration damper. A predictive shift strategy, which works in conjunction with the car’s navigation system – even when route guidance is not active – ensures that gear changes are timed precisely according to the prevailing driving situation.
The eight-speed Sport Automatic transmission is available as an option for the BMW 125i, BMW M135i, BMW 120d and BMW 120d xDrive models. This transmission is standard on the BMW 125d. It features even faster gearchanges, shift paddles on the steering wheel and a Launch Control function.
The new BMW 1 Series features an expanded range of BMW EfficientDynamics features. As well as Brake Energy Regeneration, the need-based operation of ancillary components, Electric Power Steering, the Optimum Gearshift Indicator and the Auto Start Stop function (also available in conjunction with an automatic transmission), standard equipment for the new BMW 1 Series model range also includes ECO PRO mode, which can be activated using the included Driving Experience Control switch. On all cars specified with an automatic transmission – with the exception of the BMW 118i and the BMW 120i – ECO PRO mode now also offers a coasting function. In addition, vehicles with the Professional Navigation system come with a Proactive Driving Assistant function, which tells the driver when to lift off the throttle ahead of, say, corners, turn-offs, roundabouts and speed limits.
There have also been aerodynamic improvements, with the newly designed front apron and improved sealing between the headlights and bonnet optimising airflow. The BMW 116d EfficientDynamics Plus model also features active air flap control and specially designed kidney grille bars. With these measures in place, the new BMW 1 Series models have a lower drag coefficient (Cd) than that of their predecessors. The Cd of the new BMW 116d EfficientDynamics Plus model, for example, has been reduced to 0.29.
The BMW 1 Series is offered in three trims – SE, Sport and M Sport.
The new BMW 1 Series is on sale now, priced at £20,245 for a three-door 118i SE and £20,775 for a five-door 118i SE.
