Nissan continues to fine-tune its Juke small crossover, which has received some mechanical tweaks in Europe that promise to further reduce emissions and lift fuel economy.

The Japanese company says both the 1.6-litre petrol and 1.5-litre dCi diesel drivetrains have undergone an optimisation programme that includes revised gear ratios for the manual transmission models.

As a result of these changes, the 1.6-litre petrol variant now returns 47.1mpg UK (equal to 39.2mpg US or 6.0 lt/100km) on the combined cycle, an improvement of 2.3mpg, while emitting 139g/km of CO2, a reduction of 8g/km over the previous model.

Those that opt for the revised 1.5-litre dCi diesel, will see fuel economy jump from 55.4mpg UK to 57.6mpg UK (47.9mpg US or 4.9 lt/100km) onhttp://www.blogger.com/img/blank.gif the combined cycle, and emissions drop from 134g/km to just 129g/km.

At least for the United Kingdom, where the company has sold some 22,000 Jukes since it launched exactly a year ago, Nissan says prices remain unchanged.
