BMW has confirmed a whole host of new 3-series variants, including the first all-wheel drive model to make the UK and a super-frugal ‘EfficientDynamics’ petrol variant.

The 320i xDrive saloon will go on sale in the UK in July, powered by a turbocharged 2.0-litre petrol engine with 181bhp. “Further variants will follow by the end of the year,” according to BMW, with the 320d a leading contender for all-wheel drive given its popularity in the UK.

A rear-drive version of the 320i will also form the basis for the 320i Efficient Dynamics. It uses a detuned 2.0 petrol engine with 168bhp. It’s good from 0-62mph in 7.6sec, and also economy of 54.3mpg and CO2 emissions of just 124g/km.

The 320i ED saloon goes on sale in November, at the same time as the entry-level 134bhp 316i saloon.

The other additions to the 3-series line-up planned by early 2013 are the 254bhp six-cylinder diesel 330d, the saloon-only petrol-electric ActiveHybrid 3 and the popular M Sport trim level.
