3 - BMW 320D ED
Official MPG 68.9mpg True MPG 55.2mpg
The BMW 3 Series has long been the car to beat in the junior executive class. It's spacious, refined and can also be fun to drive, and despite advances from the likes of the Jaguar XE and Audi A4 it's still one of the most well-rounded cars on offer.
2 - Volkswagen Passat 1.6 Bluemotion
Official MPG 76.3mpg True MPG 56.4mpg
If you're looking for a budget alternative to some of the more upmarket options in this list, then look no further than VW's Passat. It's every bit as classy and spacious as more premium models, and is also relaxing to drive and comes with all the equipment you need.
Official MPG 78.5mpg True MPG 57.8mpg
An executive car that can average just shy of 58mpg in our tests is worthy of praise - and this hybrid version of the C-Class is also one of the best examples of luxury and economy combined. If you're looking for an executive car that will also offer relatively low running costs, this is it.
