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.

The 2019 Astra sets the standard for efficiency and low emissions with an all-new range of petrol and diesel powertrains. 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.

Meticulous development in the wind tunnel also made a significant contribution to the reductions in fuel consumption and CO2 emissions of up to 21 per cent versus the outgoing model.

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.

The Astra’s chassis has undergone a number of improvements, too. New dampers provide greater bump control, even on poor surfaces, while the steering has received a new calibration, resulting in improved handling at higher speeds.

The new turbocharged petrol and diesel engines, which are as economical as they are lively, are primarily responsible for a marked improvement in Astra’s efficiency. The low consumption and CO2 figures are also thanks to the Astra’s six-speed manual gearboxes, the seven-speed continuously variable transmission (CVT) and – for the first time at Vauxhall – a new nine-speed automatic.

The compact, three-cylinder, turbo petrol units are available with 1.2 and 1.4-litre displacements. With the new 1.2-litre petrol engine, the Astra achieves a 6kg weight loss versus the outgoing 1.4T (150PS) engine. With power outputs extending from 110PS to 145PS and maximum torque from 195Nm to 236Nm, they achieve an excellent balance between performance and efficiency.

The Astra 1.2-litre is combined with a smooth-shifting six-speed manual gearbox while the Astra 1.4-litre is available exclusively with a new seven-speed CVT. With the CVT, Astra drivers can enjoy the convenience of automatic gear changing or select gears themselves via the shift lever.

Integration of the water-cooled exhaust manifold in the cylinder head contributes to quick engine warm-up, which lowers emissions after a cold start.

Typical for Vauxhall is the excellent transient throttle response of the petrol engines – at 1,500 rpm.



Diesel Engines

The Astra’s 1.5-litre, three-cylinder diesel engines offer 105PS and 122PS, as well as 260Nm to 300Nm of torque. The common rail fuel injection system operates at up to 2,000 bar.

As an alternative to the standard six-speed manual gearbox, the most powerful diesel is available with the option of a smooth-shifting new nine-speed automatic transmission, which is makes its debut in the new Astra.

The new diesel engines feature an electrically-activated turbocharger with variable geometry turbine vanes and, like their petrol counterparts, a balance shaft in the block for additional refinement. Likewise, the exhaust manifold is also integrated in the cylinder head.

Optimum exhaust after-treatment of the Astra 1.5 diesel is delivered by the emissions reduction system consisting of a passive oxidation catalyst, AdBlue injector, SCR catalyst and Diesel Particulate Filter.
