2014 BMW 5 Series revealed

This is the 2014 BMW 5 Series, which gets a mild styling refresh and mechanical revisions, including a new entry-level diesel option, the 518d.

The styling revisions include new bumpers, a slightly different headlight and tail-light design, and a new line-up of alloy wheels - although the overall profile of BMW's rival for the Mercedes E-class and Audi A6 rival is unchanged.

The biggest news is the arrival of the 518d, which uses a retuned version of the same 2.0-litre four-cylinder turbodiesel engine that you'll find in the 520d. The 518d has 141bhp and 266lb ft of torque, enough to take the car from 0-62mph in 9.6sec.

However, the car returns claimed average fuel economy of 62.8mpg and it emits just 119g/km of CO2, regardless of whether it is equipped with the standard six-speed manual gearbox or BMW's optional eight-speed automatic.

The 520d also gets a retune; it has 181bhp, and can crack the 0-62mph dash in a more spritely 8.1sec, yet it delivers the same CO2 figure as the 518d (again, with either manual or automatic). The regular 520d's improvements mean that the 520d Efficient Dynamics has been deemed surplus to requirements, so it's being dropped from the range.
