If you're doing higher mileages of around 20,000 miles year or more then the diesel Mazda 6 is for you -with fuel economy figures far in advance of the petrol's, to the tune of an extra 10-125 mpg or so depending on your driving style, it will save you a considerable amount every year. Available in both the saloon and estate, and optionally with an automatic gearbox, the 2.2 diesel comes in 2 power levels - 150 horsepower and 184 horsepower for an extra £1,500 on the price. The extra power takes the 0-60 from 10 secs in the 150 down to 8.5 in the 184, and top speed adds an extra 10 mph from 131 to 141 miles per hour. We'd suggest a test drive in both to see which suits you better.
