We often hear extravagant claims by car makers about the fuel efficiency of their cars, only to be disappointed by their real-world performance. Sometime they even have to apologize for lying. Now Skoda has made a new Superb GreenLine which they promise will do more than 1,100 miles on just one tank of fuel in the real world.

The key to this astonishing economy, which is the result of averaging 76.4mpg (with CO2 emissions of 96g/km) is a 1.6-litre four-cylinder diesel. It gives Skoda Superb GreenLine 120 horsepower which sounds about right for a family car. The frugal engine is complemented with other fuel saving measures such as tart-stop ignition and brake energy recovery, longer gear ratios, SCR (Selective Catalytic Reduction) and 16-inch reduced rolling resistance tires.

True to its name, Skoda Superb GreenLine also comes with a couple of exclusive feature to make sure its emissions are as clean as technically possible. They are an oxidation catalytic converter and a diesel particulate filter. Together, and with the help of reducing agent AdBlue, they treat the diesel exhaust gases, reducing nitrogen oxide and saving fuel. The new model  will be unveiled to the public at next month’s Frankfurt Motor Show and will be available in the UK later this year.
