6 - Audi A3 saloon 1.6 TDI Sport
Official MPG 72.4mpg True MPG 52.7mpg
Compact executive cars don't come much better than the Audi A3 saloon. It's excellent to drive, offers low running costs and has a truly classy interior. We named the A3 hatchback as our Car of the Year in 2013, so expect plenty of that award-winning DNA here too.
Official MPG 57.6mpg True MPG 53.2mpg
Kia has truly earned its place on this list with the Optima. It's a great looking executive car that's as smart inside as it is on the outside. It also comes with plenty of standard equiment and, although the driving dynamics aren't quite up to scratch, it makes a tempting case for itself.

The Mazda 6 is as appealing for families with plenty of luggage to haul around as it is for executives looking for a comfortable and economical motorway companion. In recent years it's been left behind in terms of overall comfort by more modern rivals, but the 6 still offers a flexible selection of diesel engines and stylish looks.
