BMW’s most affordable coupé model is set to appeal to an even broader set of customers with the introduction of two new engines in September. The new BMW 118d Coupé and BMW 120i Coupé have been introduced to offer the stylish lines of a coupé in a package that blends performance and economy.

The BMW 118d Coupé uses the same engine that powered the 2008 World Green Car of the Year winning BMW. This four-cylinder diesel powerplant with third generation common rail diesel technology achieves an impressive 119g/km CO2 emissions figure and a combined consumption of 62.8mpg, making it the cleanest and greenest diesel-powered sports coupé available. Performance is equally impressive with the 118d Coupé recording a zero to 62mph time of 9.0 seconds before going on to a top speed of 130mph.

The BMW 120i Coupé is powered by a Hams Hall built 1,995cc engine producing 170hp to hussle it from zero to 62mph in 7.8 seconds and on to a 139mph top speed. The four-cylinder engine is still capable of achieving 42.8mpg on the combined cycle and recording CO2 emissions of 153g/km.
