2021 Vauxhall Astra Mk VIII 1.5 Turbo D (130 Hp) Automatic

The Vauxhall Astra Mk VIII 1.5 Turbo D (130 hp) Automatic, launched in November 2021, represents a key offering within the eighth generation of Vauxhall’s popular compact hatchback. Positioned as a fuel-efficient and practical option, this variant caters to drivers seeking a balance between performance and economy. It’s built on the EMP2 platform, shared with other Stellantis group vehicles like the Peugeot 308 and Opel Astra, and signifies a move towards more modern engine technology and driver-assistance features for the Astra line. This specific configuration aimed to provide a comfortable and refined driving experience, particularly suited for longer commutes and motorway journeys.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Astra Mk VIII 1.5 Turbo D Automatic is the F15DTH engine, a 1.5-liter inline-four cylinder diesel. This engine utilizes a common-rail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for optimized combustion. A turbocharger with an intercooler is employed to boost power output and improve efficiency. The engine features a Double Overhead Camshaft (DOHC) valvetrain, contributing to efficient valve control and improved engine breathing. The 130 hp output is achieved at 3750 rpm, while peak torque of 300 Nm (221 lb-ft) is available from just 1750 rpm, providing good low-end responsiveness. Paired with this engine is an eight-speed automatic transmission, designed for smooth gear changes and efficient power delivery. This transmission is a crucial component in maximizing fuel economy and providing a comfortable driving experience.

Driving Characteristics

The 1.5 Turbo D Automatic offers a composed and refined driving experience. While not a performance-oriented variant, the 130 hp engine and eight-speed automatic provide adequate power for everyday driving situations. Acceleration from 0-60 mph takes approximately 10.6 seconds, and the car reaches a top speed of 129.87 mph. The automatic transmission is well-tuned, offering smooth shifts and a willingness to downshift when needed. The gear ratios are optimized for fuel efficiency, but also provide enough punch for overtaking maneuvers. Compared to the manual version of the same engine, the automatic offers greater convenience, especially in urban traffic. However, it does slightly diminish fuel economy and responsiveness. Compared to higher-output Astra variants, such as those with petrol engines, the 1.5 Turbo D Automatic prioritizes fuel efficiency and torque over outright speed.

Equipment & Trim Levels

The Astra Mk VIII 1.5 Turbo D Automatic was typically offered in mid-range trim levels, such as ‘Design’ or ‘GS Line’. Standard equipment generally included features like a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a digital instrument cluster, automatic climate control, and a suite of safety features including lane departure warning, automatic emergency braking, and cruise control. Interior upholstery was typically cloth, with options for leather upgrades. Optional extras could include a panoramic sunroof, heated seats, and a premium sound system. The trim level dictated the level of exterior styling, with GS Line models featuring more aggressive body styling and sporty accents.

Chassis & Braking

The Astra Mk VIII utilizes a MacPherson strut front suspension and a torsion beam rear suspension. This setup provides a good balance between ride comfort and handling. The chassis is relatively lightweight, contributing to the car’s agility. Braking is handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) is standard, along with Electronic Stability Control (ESC). The steering is electrically assisted, providing a light and precise feel. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The Astra Mk VIII 1.5 Turbo D Automatic was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and well-equipped interior. However, some reviewers noted that the engine could feel a little underpowered, particularly when fully loaded. Compared to other diesel-powered hatchbacks in its class, such as the Volkswagen Golf and Ford Focus, the Astra offered a competitive level of equipment and fuel economy. The automatic transmission was also considered to be a strong point, offering smooth and refined gear changes. In terms of reliability, the F15DTH engine has proven to be generally robust, although regular servicing is essential to maintain optimal performance.

Legacy

The Vauxhall Astra Mk VIII 1.5 Turbo D Automatic represents a significant step forward in terms of technology and refinement for the Astra line. The powertrain, while not the most powerful in the range, offers a compelling combination of fuel efficiency, practicality, and comfort. On the used car market, these models are becoming increasingly popular due to their affordability and low running costs. The F15DTH engine is known for its durability, provided it has been properly maintained. As with any diesel engine, it’s important to check for signs of wear and tear, such as excessive smoke or unusual noises. Overall, the Astra Mk VIII 1.5 Turbo D Automatic remains a sensible and well-rounded choice for buyers seeking a practical and economical compact hatchback.
