The Vauxhall Antara 2.0 CDTi ECOTEC (150 hp) 4×4 Automatic, produced between 2006 and 2010, represented a key offering in Vauxhall’s foray into the compact SUV segment. Positioned as a mid-range trim within the Antara lineup, it aimed to provide a balance between fuel efficiency, all-weather capability, and comfortable practicality. The Antara itself was Vauxhall’s version of the Opel Antara, sharing its platform – the GM Theta – with vehicles like the Chevrolet Captiva. This model was primarily targeted at the European market, offering a more affordable and accessible SUV option compared to premium competitors.

Powertrain & Engine Architecture
The heart of the Antara 2.0 CDTi was the Z20DMH engine, a 2.0-liter four-cylinder diesel. This engine belonged to the GM/Fiat family of common rail direct injection diesels. It featured a turbocharger with an intercooler to boost power and efficiency. The engine utilized a double overhead camshaft (DOHC) valvetrain, optimizing gas flow for improved performance. The common rail diesel injection system, operating at very high pressures, allowed for precise fuel delivery and reduced emissions. The 5-speed automatic transmission was a conventional hydraulic automatic, chosen for its smoothness and ease of use, although it wasn’t known for being particularly sporty or fuel-efficient compared to manual alternatives.
Driving Characteristics
The 150 hp output and 320 Nm of torque provided adequate, but not exhilarating, performance. Acceleration from 0-60 mph took around 11.5 seconds, and top speed was approximately 110.6 mph. The automatic transmission, while comfortable, resulted in a noticeable difference in responsiveness compared to the manual versions. Gear changes were generally smooth, but could feel somewhat hesitant during quick overtaking maneuvers. The 4×4 system provided enhanced traction in slippery conditions, making it a capable all-weather vehicle. However, it wasn’t designed for serious off-roading. The power delivery was fairly linear, with peak torque available from 2000 rpm, making it suitable for everyday driving and towing.
Equipment & Trim Levels
The 2.0 CDTi ECOTEC Automatic typically came with a reasonable level of standard equipment. This included air conditioning, electric windows, central locking, and an audio system with CD player. Higher trim levels, often denoted by ‘SE’ or ‘Design’ badges, added features like alloy wheels, climate control, parking sensors, and upgraded interior trim. Interior upholstery was typically cloth, with leather options available as an extra. The dashboard layout was functional and straightforward, prioritizing usability over stylistic flair. Optional extras included a sunroof, navigation system, and heated seats.
Chassis & Braking
The Antara featured independent suspension all around – McPherson struts at the front and a multi-link setup at the rear – providing a comfortable ride quality. Stabilizer bars were fitted to both axles to reduce body roll during cornering. Braking was handled by ventilated discs at the front and solid discs at the rear, coupled with an Anti-lock Braking System (ABS). The suspension was tuned for comfort rather than outright handling prowess, prioritizing a smooth ride over sporty dynamics. The 4×4 system was typically an on-demand system, engaging the rear wheels when traction was lost at the front.
Market Reception & Comparison
The Antara 2.0 CDTi Automatic was generally well-received as a practical and affordable SUV. Critics praised its comfortable ride, spacious interior, and all-weather capability. However, the automatic transmission was often criticized for being somewhat sluggish and impacting fuel economy. Compared to the more powerful 2.4-liter petrol version, the 2.0 CDTi offered significantly better fuel economy and lower running costs, making it a more sensible choice for many buyers. Against competitors like the Nissan Qashqai and Kia Sportage, the Antara offered a competitive package, but often lacked the brand prestige of some rivals.
Legacy
The Z20DMH engine, while generally reliable, is known to require regular maintenance, particularly regarding the diesel particulate filter (DPF) and turbocharger. The automatic transmission, if not serviced regularly, can experience issues with harsh shifting. Today, the Antara 2.0 CDTi Automatic represents an affordable entry point into the SUV market. Well-maintained examples can still provide reliable transportation, but potential buyers should be aware of the potential maintenance costs associated with a diesel engine and automatic transmission of this age. Its lasting appeal lies in its practicality, affordability, and the added security of all-wheel drive.
