BMW is extending the 1 Series line-up in the UK with a new Coupé model, which includes a diesel capable of 58.9mpg.
The new BMW 1 Series Coupé goes on sale in the UK in November and will be available in 120d, 123d and 135i guises. The 135i marks the first time a twin-turbo petrol engine has powered a 1 Series, while the 123d becomes the world’s most powerful production four-cylinder diesel engine.
The 120d achieves a combined economy figure of 58.9mpg and emissions of just 128g/km, while its 1995cc four-cylinder engine produces 177hp and a zero to 62mph time of 7.6 seconds.
BMW’s EfficientDynamics programme helps with these figures; the 120d comes with Auto Start-Stop technology, Brake Energy Regeneration, third-generation common-rail fuel injection, a diesel particulate filter, active aerodynamics, Electric Power Steering and low rolling resistance tyres.
The 204hp four-cylinder engine in the BMW 123d Coupé is the first four-cylinder production diesel to come with twin-turbo technology. Its 1995cc powerplant is the world’s first all aluminium diesel to have an output per litre figure in excess of 100hp. This performance equates to a zero to 62mph time of 7.0 seconds and a top speed of 148mph – previously unheard of figures in such small capacity production diesels. It also has emissions of just 138g/km which sees it fall into Band C for Vehicle Excise Duty, and the fuel consumption figure on the combined cycle is 54.3mpg.
Like every other BMW, except xDrive models, the new BMW 1 Series Coupé has 50:50 weight distribution and a front-engine, rear-wheel-drive configuration. The 1 Series Coupé has a double-joint spring strut front axle arrangement with a five-link rear suspension, allowing the fine tuning of the ride characteristics of the car.
Dynamic Stability Control is standard on the 120d Coupé and Dynamic Traction Control is a further function of DSC that permits a greater degree of wheelslip for more spirited driving. The BMW 123d and the 135i come as standard with Dynamic Stability Control+ with its five additional safety features of Soft Stop, Hill start assistant, Brake Drying, Brake pre-tensioning and Brake fade compensation.
The BMW 120d Coupé will be available in ES, SE and M Sport guises, while the 123d Coupé will be offered in SE and M Sport and the 135i Coupé just as an M Sport.
Prices for all three models will be announced closer to the November sale date.
