VAUXHALL will launch a diesel-fuelled Tigra in January capable of more than 60mpg and with carbon dioxide emissions of 124g/km.

Using the same 1.3-litre CDTi engine found in the Corsa, the diesel Tigra promises significant running cost savings over petrol-fuelled roadsters with a combined fuel consumption figure of 61.4mpg, compared with the petrol 1.4-litre variant offering 46.3mpg.

Based on a driver covering 12,000 miles a year, the diesel Tigra offers fuel savings of up to £225 a year over the 1.4 litre model, and more than £500 over a 1.8-litre variant.

Like the Corsa, the Tigra 1.3 CDTi will be Euro IV-compliant and produces 69bhp and 125lb-ft of torque.

Although prices have not yet been confirmed, the diesel Tigra is expected to cost about £14,500.
