BMW’s 3-series Coupé will come with a choice of six-cylinder petrol or diesel engine next month.

The most popular model in the BMW portfolio now encompasses a new twin-turbo 3.0-litre petrol engine, to be badged 335i, and a single turbocharged diesel engine called the 325d.

Joining these two new units is the most powerful diesel ever to power a BMW in the UK - a twin-turbocharged 2,993cc engine with 286hp.

Prices range from £27,310 to £36,905 on-the-road.
