The Nissan Juke is now available with a cleaner, more efficient version of its 1.5-litre diesel engine.
Average economy for the 1.5 dCi rises to 67.3mpg (from 58.9mpg) and CO2 emissions fall to 109g/km (from 124g/km).
That adds around 80 miles of range for every tank of fuel, and cuts 85 from the car's annual road tax bill.
Company car drivers on the lower-rate tax band should see their annual liability drop by around 90 compared with the previous version's cost.
The new 1.5 gets a modest increase in torque and its engine noise has been reduced the latter should help to address one of our criticisms of the diesel Juke.
It also gets stop-start technology, which was previously available on only the petrol models.
The new Nissan Juke 1.5 dCi is on sale now, with prices starting at 14,895 for entry-level Visia trim.
