The Opel/Vauxhall Astra could now be availed with the new generation 1.6 CDTi engine, regarded as the brand’s cleanest mid-size diesel. Opel/Vauxhall is set to unveil the new diesel engine in the Astra at the Geneva Motor Show in March. The new diesel engine is available in two power outputs: 110PS and 136PS, in both hatchback and Sports Tourer body styles.
The 110PS variant returns 76.3mpg combined with emission of just 97g of carbon dioxide per, while the 136PS variant achieves 72.4mpg combined and emits 104g of CO2 per km. The new 1.6 CDTi is considered as one of the best engines in its class in terms of noise and vibration -- all thanks to a combustion process made efficient with multiple injection, re-designed parts and acoustic covers.
The Euro 6-compliant engine is also super-refined, clean and powerful. Efficiency is improved by a high-pressure common rail injection system as well as a lean NOx trap exhaust-after treatment (LNT).
On the other hand, power is enhanced by a variable turbine turbocharger. Vauxhall and Opel have spent over EUR50 million in the development of five and six-speed transmissions. The six-speed transmission paired to the 1.6 CDTi features a revised gear change and an improved faster shift quality.
