Suzuki has introduced a new 1.3-litre DDiS engine to the Swift range.
Available from the beginning June the new four-cylinder, 74bhp turbocharged diesel engine emits 109g/km of Co2, a nine per cent improvement over the 1.3 diesel version of the previous Swift.
Fuel consumption also improves by eight per cent to 67.3mpg combined, which Suzuki estimates gives a range of over 500 miles.
The Euro V engine will power the Swift from 0-62mph in 12.7 seconds, giving the car a top speed of 103mph.
Prices start from £12,890 for the five-door model with standard equipment including seven air bags, air conditioning, 16-inch alloys, USB port and heated electric door mirrors.
