6. Volvo S90 D4
Official fuel economy: 64.2mpg; True MPG: 39.9mpg; Shortfall: 37.8%
Like the Jaguar XF, the distinctly Swedish Volvo S90 is an appealing alternative to Audi’s A6 and BMW’s 5 Series. Thanks to new compressed air technology that helps the car’s turbocharger kick in more quickly, the smaller D4 diesel engine has a decent turn of speed. The fact that it’s capable of stretching almost 40 miles out of a gallon of fuel is an added bonus.
5. Audi A4 2.0 TDI 190
Official fuel economy: 65.9mpg; True MPG: 42.0mpg; Shortfall: 36.2%
We like the Audi A4 so much that it’s our current Executive Car of the Year and it was last year’s overall What Car? of the Year. It may not be as involving to drive as a BMW 3 Series or Jaguar XE, but the A4 has the plushest, quietest interior and, if you go for the more powerful 2.0 diesel you’ll get more than 40mpg in real-world driving.
