BMW has announced a raft of changes to the 3 Series range with the aim of offering owners more power and torque with lower fuel consumption and emissions.

The BMW 3 Series Coupé and Convertible receive design changes and the company will also launch the BMW 320d EfficientDynamics Saloon - its cleanest 3 Series ever.

All the new engines and models make their debut in the UK market on March 20, 2010 and all conform to EU5 emissions standards.

Tim Abbott, managing director of BMW UK, said: "The BMW 3 Series Coupé and Convertible were already class-leading models, but we have no intention of sitting on our laurels and are offering customers more of what they want - on-road performance and ever more fuel efficiency with lower CO2 emissions combined with a refreshed look inside and out.”
