Aerodynamic features include an active aero-shtter in the radiator grille which will react to different speeds and loads automatically to aid in fuel efficiency.

The latest Vauxhall Astra ecoFLEX will utilise technology including energy recuperation and adaptive aerodynamics in order to achieve a combined fuel consumption of 76.3mpg and CO2 emissions of 99g/km.

A result of the sub 100g/km means exemption from the London Congestion Charge and zero Vehicle Excise Duty, inclusion in the lowest 13 per cent Benefit in Kind tax band and 100 per cent capital allowance for businesses.

The Vauxhall Astra's 1.7 CDTi diesel engine provides 130PS and 300Nm. Compared to the Vauxhall Astra 1.7 CDTi 125PS, the new engine emits 20g/km less CO2 thanks to an all new engine management system with a reduced compression ratio and a new fuel injection system with eight injections per cycle at 1800 bar. A new variable geometry turbocharger providing greater boost-pressure control.

A friction-reduced six speed gearbox is fitted to the new Vauxhall Astra ecoFLEX, tuned to work with the new engine version. A shift indicator features between the speedometer and rev-counter to provide the driver with the best time to change up and a graphic-assist function helps with adopting the most fuel efficient driving style.

Aerodynamic features include an active aero-shutter in the radiator grille which will react to different speeds and loads automatically to aid in fuel efficiency, staying open at low speeds and when more throttle is required and then closing at higher cruising speeds, mean air is diverted around rather than through the grille which improves the car's aerodynamics.

The Vauxhall Astra's ride height has been lowered by 12mm, meaning less wind resistance, and low rolling resistance tyres are available with a choice of 215/60 x 16 or 225/50 x 17 sizes.

For the first time the 1.7 CDTi engine is fitted with Start/Stop technology, currently available on the 1.3 and 2.0 CDTi versions. With this technology, the engine is automatically shut down when neutral is engaged and clutch pedal released. When first gear is engaged, the engine will re-start.
