Executive saloons might require a bigger initial outlay if you pay the asking price in full, but buyers expect running costs to be fiercely competitive.
Our fuel testers have been out in all manner of saloons, including big-sellers in this segment like the BMW 3 Series and Mercedes-Benz C-Class, as well as cars from Volkswagen, Audi and Mazda.
These cars should be on the shortlist for anyone looking for a smart saloon with fuel efficiency as a top priority because all offer in excess of 50mpg.
10 - Volvo S60 2.0 D3
Official MPG 50.4mpg True MPG 42.2mpg
Volvo's S60 offers a classy, comfortable interior and comes loaded with plenty of standard equipment. It's just a shame that it's not quite as good to drive as its German rivals, and resale values are weak.
9 - Lexus GS300h 2.5 SE CVT Hybrid
Official MPG 60.1mpg True MPG 51.4mpg
Most of the GS's rivals rely on diesel power, so the big Lexus has something of a unique selling point in this class. It's comfortable and offers plenty of equipment, but is hampered by a small boot and a poor CVT gearbox.
8 - Toyota Avensis 1.6 TR D-4D
Official MPG 67.2mpg True MPG 52.5mpg
Truthfully, most of the Avensis's rivals offer a more competitve and well-rounded package, but Toyota's long-held reputation for reliability and a long warranty help to make this car an appealing prospect.
7 - BMW 420d 2.0 SE
Official MPG 60.1mpg True MPG 52.5mpg
The 4 Series is a classy and fun four-seat coupé. There's room for four passengers inside and it's also fun to drive. In fact, only a few unrefined diesel engines let this let this Audi A5 and Mercedes-Benz C-Class Coupé rival down.
