Vauxhall adds cleanest ever mid-size diesel to Astra line-up
Previously only available on the Zafira Tourer and the Meriva, the new engine is offered in two power outputs: 108bhp and 134bhp, in both hatchback and Sports Tourer body styles.
The 108bhp version achieves 76.3mpg combined with CO2 emissions of 97g/km, with 72.4mpg combined and 104g/km in 134bhp guise.
In addition to its efficiency gains, the new 1.6 CDTi is said to be one of the best engines in its class for noise and vibration thanks to an efficient combustion process with multiple injection, re-designed components and the use of acoustic covers.
The Euro6-compliant also features a high-pressure common rail injection system and lean NOx trap exhaust-after treatment (LNT) to improve efficiency, with a variable turbine turbocharger to aid performance.
The new unit is married up to a six-speed ’box with a revised gear change and improved shift quality.
The 1.6 CDTi Astra is available to order now with first deliveries expected from April. Prices start from £17635 for the 108bhp five-door hatchback in Design trim.
