BMW is extending the 1 Series line-up in the UK with a new model consisting of a brace of high performance twin-turbocharged engines and a diesel capable of a frugal 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 launch of the 123d heralds the introduction of the world’s most powerful production four-cylinder diesel engine.
The flagship of the range is the BMW 135i with its 3.0-litre twin-turbocharged petrol powerplant. Offering 306hp from its light alloy and magnesium straight-six engine, the 135i is capable of accelerating from zero to 62mph in 5.3 seconds before going on to an electronically-limited top speed of 155mph. Peak torque of 400Nm from just 1,300rpm through to 5,000rpm ensures smooth yet rapid progress and in-gear flexibility. Courtesy of High Precision Direct Injection for the most efficient burn of fuel mix and Bi-VANOS variable valve technology combined with lightweight engineering principles, the BMW 135i is capable of frugal motoring while maintaining its top end performance. The 2,979cc engine posts a 30.7mpg figure on the combined cycle and a CO2 emissions.
