1989-1991 Vauxhall Astra Mk II CC 1.7 D (57 Hp)

Technical Specifications

The Vauxhall Astra Mk II CC 1.7 D, produced between 1989 and 1991, was an economy-focused variant within the broader Mk II Astra range. The “CC” designation indicated the coupe/three-door body style, distinguishing it from the five-door hatchback and estate versions. This particular model, powered by a 1.7-liter diesel engine producing 57 horsepower, catered to buyers prioritizing fuel efficiency and low running costs over outright performance. It occupied the entry-level position in the Astra Mk II diesel lineup, offering a more affordable alternative to the slightly more powerful, though still modest, diesel options available.

Powertrain & Engine Architecture

The heart of the Astra Mk II CC 1.7 D was the 17D engine, a naturally aspirated, indirect injection diesel engine. This engine utilized a precombustion chamber design, a common feature in diesel engines of the era. Fuel was injected into a small precombustion chamber within the cylinder head, where it ignited and then ignited the main charge in the cylinder. This system aided in cold starting and reduced engine noise compared to direct injection systems. The engine featured a simple two-valve per cylinder configuration and a relatively low compression ratio of 23:1. The 57 horsepower output was achieved at 4600 rpm, while peak torque of 105 Nm (77.44 lb-ft) arrived at 2400 rpm. The engine was transversely mounted at the front of the vehicle, driving the front wheels. The five-speed manual transmission was a standard feature, chosen for its efficiency and durability rather than sporty performance.

Driving Characteristics

The 1.7 D-powered Astra Mk II CC was not known for its performance. With only 57 horsepower, acceleration was leisurely, and overtaking required careful planning. The five-speed manual transmission was geared to maximize fuel economy rather than provide spirited driving. Gear ratios were relatively tall, emphasizing efficiency over responsiveness. Compared to the gasoline-powered Astra variants, or even the slightly more powerful diesel options, the 1.7 D felt significantly slower. However, the engine proved to be durable and relatively refined for a diesel of its time, offering acceptable levels of noise and vibration. The focus was on providing economical transportation, and in that regard, it succeeded. The car’s handling was predictable, but not particularly engaging, prioritizing comfort and stability over sporty cornering.

Equipment & Trim Levels

The 1.7 D trim level was typically the base model in the Astra Mk II CC range. Standard equipment was fairly basic, reflecting its position as an affordable option. Interior upholstery was typically cloth, with a simple dashboard layout. Features like central locking, electric windows, and a sunroof were either optional extras or reserved for higher trim levels. The Astra Mk II CC 1.7 D often came equipped with a basic radio as standard, but more advanced audio systems were available as options. The exterior trim was also minimal, with steel wheels and black plastic bumpers being common features. The overall interior aesthetic was functional and utilitarian, prioritizing durability over luxury.

Chassis & Braking

The Astra Mk II CC utilized a MacPherson strut front suspension and a twist-beam rear suspension. The suspension setup was tuned for comfort and stability rather than sporty handling. Braking was typically accomplished with disc brakes on the front wheels and drum brakes on the rear. The braking system was adequate for the vehicle’s weight and performance, but lacked the stopping power of more modern systems. Stabilizer bars were often omitted on the base 1.7 D trim, further contributing to a softer, more comfortable ride. The steering was a rack and pinion system, providing reasonable precision, though it lacked the feedback of more sophisticated setups.

Market Reception & Comparison

The Astra Mk II CC 1.7 D was well-received by buyers seeking an economical and reliable hatchback. Critics acknowledged its fuel efficiency and low running costs, but often criticized its lack of performance. Compared to the gasoline-powered Astra variants, the 1.7 D offered significantly better fuel economy, but at the expense of acceleration and overall driving enjoyment. Against other diesel hatchbacks of the time, such as the Ford Escort Diesel, the Astra 1.7 D offered a competitive package in terms of price and fuel efficiency. Its simplicity and robust construction contributed to its reputation for reliability. It was seen as a practical and sensible choice for those on a budget.

Legacy

The 17D engine, while not a powerhouse, proved to be a durable and long-lasting unit. Astra Mk II CC 1.7 D models are now considered classic cars, and well-maintained examples are sought after by enthusiasts and collectors. The powertrain’s simplicity makes it relatively easy to maintain and repair, even today. While not a particularly desirable or valuable classic, the Astra Mk II CC 1.7 D represents a significant part of Vauxhall’s history and a testament to the enduring appeal of economical and reliable transportation. Finding one in good condition today is becoming increasingly rare, but those that remain offer a glimpse into a bygone era of automotive engineering. The car’s enduring appeal lies in its honest simplicity and its ability to provide affordable transportation without significant fuss.
