2004-2009 Vauxhall Astra Mk V CC 1.9 CDTi (150 Hp)

The Vauxhall Astra Mk V CC 1.9 CDTi, produced between 2004 and 2009, represented a significant offering in the British compact car market. Part of the Mk V Astra range (designated as the H-series internally), the CC – or Coupe – body style offered a more practical alternative to traditional three-door coupes, featuring a five-door configuration with a sloping roofline. This particular variant, powered by the 1.9-liter CDTi diesel engine producing 150 horsepower, aimed to balance fuel efficiency with respectable performance, positioning itself as a mid-range option within the broader Astra lineup. It was a popular choice for drivers seeking a stylish, economical, and practical vehicle for daily commuting and family use.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Astra Mk V CC 1.9 CDTi was the Z19DTH engine, a 1.9-liter, four-cylinder diesel. This engine was a product of Fiat’s JTD (Jet Turbo Diesel) technology, licensed to Vauxhall/Opel. It featured a common rail direct injection system, delivering fuel at extremely high pressure for improved combustion efficiency and reduced emissions. The engine utilized a variable geometry turbocharger (VGT) and an intercooler to boost power output and torque. The VGT allowed the turbocharger to optimize boost pressure across a wider range of engine speeds, enhancing both low-end responsiveness and high-end power. The engine produced 150 horsepower at 4000 rpm and a substantial 315 Nm (232 lb-ft) of torque at just 2000 rpm. This torque figure was a key characteristic, providing strong pulling power for everyday driving and overtaking. The six-speed manual transmission was the standard offering for this variant, providing a good balance between fuel economy and driver control. The gear ratios were tuned to maximize the engine’s torque output, offering brisk acceleration and comfortable cruising.

Driving Characteristics

The 1.9 CDTi engine, coupled with the six-speed manual gearbox, provided a surprisingly engaging driving experience. While not a sports car, the Astra CC 1.9 CDTi offered ample power for confident overtaking and merging onto highways. The strong low-end torque meant that drivers didn’t need to rev the engine excessively to achieve good acceleration. The gear ratios were well-matched, allowing for smooth and efficient gear changes. Compared to the lower-powered 1.7 CDTi variant, the 1.9 CDTi offered a noticeable performance improvement. It also felt more refined and less strained during highway cruising. Compared to the more powerful 2.0 CDTi models, the 1.9 CDTi prioritized fuel economy and offered a more accessible price point, making it a more practical choice for many buyers.

Equipment & Trim Levels

The Astra Mk V CC 1.9 CDTi typically came equipped with a reasonable level of standard features. These included air conditioning, electric front windows, a CD stereo, and central locking. Higher trim levels, such as Design or Sport, added features like alloy wheels, upgraded upholstery, a multi-function steering wheel, and climate control. Optional extras included a sunroof, parking sensors, and a more advanced audio system. Interior upholstery was typically cloth, with higher trims offering partial leather options. The dashboard layout was functional and straightforward, with easy-to-read gauges and controls.

Chassis & Braking

The Astra Mk V CC utilized a MacPherson strut front suspension and a torsion beam rear suspension. This setup provided a good balance between ride comfort and handling. The front brakes were ventilated discs, offering good stopping power, while the rear brakes were solid discs. The steering was hydraulically assisted, providing a reasonably direct and responsive feel. The 16-inch alloy wheels, often standard on this trim, were fitted with 205/55 R16 tires, providing adequate grip in most conditions.

Market Reception & Comparison

The Astra Mk V CC 1.9 CDTi was generally well-received by automotive critics. It was praised for its fuel efficiency, strong performance, and practical hatchback body style. Critics noted that the diesel engine was relatively refined for its time, with acceptable levels of noise and vibration. Compared to rivals like the Ford Focus and Volkswagen Golf, the Astra offered a competitive package in terms of price, features, and running costs. The 1.9 CDTi engine was considered a reliable unit, although regular servicing was essential to maintain optimal performance. Fuel economy was a key selling point, with combined figures averaging around 40.6 US mpg.

Legacy

The Astra Mk V CC 1.9 CDTi remains a relatively common sight on used car lots today. The Z19DTH engine, while not without its potential issues (such as potential turbocharger wear and EGR valve problems), is generally considered a durable and reliable unit when properly maintained. Parts availability is good, and repair costs are typically reasonable. The Astra Mk V CC 1.9 CDTi represents a solid and practical choice for buyers seeking an affordable and economical compact car with a decent level of performance and equipment.
