Top fuel-efficient company saloons

  • Find out which saloon cars have the best fuel economy
  • Trim and engine choices explained
  • All have fuel economy over 60mpg

Getting the most out of a tank of fuel is always important, especially if you only claim back your business miles.

Fuel economy is of course affected by driving style and the types of journeys that you do, however picking the right car also plays an important part.

Although official fuel economy figures can seem unrealistic while out on the road, they do help to provide a benchmark to compare cars against one another.

Here we have picked the top diesel company saloons, all with fuel economy over 60mpg.

1.     Audi A3 Saloon - 74.3mpg

Audi is known for luxury but for many years now its engine efficiency has also been making the headlines.

We’ve chosen Sport as the trim of choice which includes an array of equipment as standard including DAB Radio, Bluetooth, 17-inch alloy wheels, dual-zone air conditioning, front centre armrest, sports suspension, eight speakers and USB port.

It’s also pretty cheap to tax too thanks to a low list price.

Our trim of choice would be the middle of the range SE-L trim which includes 17-inch alloy wheels, cruise control, dual-zone air conditioning, rain sensors, front and rear parking sensors, USB port, tinted glass and Bluetooth.

The C-Class is Mercedes-Benz's biggest seller and impressed us when we drove it recently, achieving a rare full five-stars in our review.

In SE trim the new C-Class comes well equipped with 16-inch alloy wheels, leather interior, reversing camera, rain sensor wipers, cruise control, DAB Radio a seven-inch multimedia system.

5.     Peugeot 508 - 70.6mpg

If you think company car saloon, the Peugeot 508 is unlikely to be the first car you think of.

Comfortable and practical, the Peugeot 508 boasts a strong engine line-up and offers good value for money.

The trim of choice here would be the middle of the range Active trim coupled with the 1.6e-HDi semi-automatic gearbox which lowers emissions to 104g/km. Despite the small premium over the manual, tax costs will be lower.

6       BMW 3 Series - 68.9mpg

Nothing says ‘I drive a company car’ quite like a BMW and a list like this would not be complete without one.

The BMW 3 Series has picked up a string of awards since the latest generation was launched in 2012 and is one of the most popular company cars in the UK.

As well as good interior quality and a refined engine range, drivers can also enjoy 163bhp which is one of the highest outputs on offer in this list.

7.       Volkswagen Passat - 68.9mpg

The Volkswagen Passat is a big seller in the company car world and it’s not difficult to figure out why with low CO2 emissions and impressive fuel economy figures as well as practical features and very high levels of comfort.

In BlueMotion guise the Passat makes even more sense for company car drivers with CO2 as low as 109g/km and fuel economy of 68.9mpg.

This is not the most powerful option available in this list though with only 104bhp, and kit levels are on the sparse side with DAB Radio, air-con, stop/start technology, front centre armrest, 16-inch steel wheels, electric windows and heated rear window among the highlights.
