Vauxhall’s latest version of the Astra, with its all-new powertrain line-up, was already 21 per cent more C0₂-efficient than the model that went before, but now new preliminary data shows further improvements to its emissions values.

All new diesel Astras now produce lower C0₂ emissions than originally quoted, with the 1.5D (105PS) engine with a 6-speed manual gearbox dropping to just 90g/km.

A summary of the changes can be found below:

	1.5D 105PS manual	1.5D 122PS manual	1.5D 122PS 9-spd auto
Hatch	95 down to 90g/km	95 down to 92g/km	120 down to 109g/km
Sports Tourer	94 down to 90g/km	94 down to 92g/km	N/A

As an example, the Astra Hatch 1.5D (105PS) 6-spd manual:

• Drops an emissions band vs previous data
• Its whole life cost drops by £113 vs previous data
• Its benefit-in-kind) drops by £163 vs previous data

With first cars arriving in showrooms this November, Vauxhall’s new Astra is on sale now.

One of the UK’s top-selling and best-loved cars, Astra is a household name for British car buyers with over three million sold in the UK over the last 40 years, including over 30,000 in 2018. More than 25 per cent of British motorists have either owned or driven an Astra, so reaction to a model with significant revisions will always be felt across the market.

Building on the wide success of the outgoing model, customers will benefit from reduced CO₂ and fuel consumption, as well as a series of class-leading technology and equipment.

With a drag coefficient figure of just 0.26, the Astra leads the class for aerodynamics. And at 0.25 Cd, the Astra Sports Tourer is also best-in-class, too. These aero-benchmarks have been achieved through numerous measures, including an engine compartment cover, deflector-shaped rear axle control arms and a full-face shutter.

The upper and lower portions of the new Astra’s radiator grille automatically open and close independently of one another, further improving the frontal airflow. The underbody optimisation improves the drag coefficient by reducing turbulence.
