The Vauxhall Zafira B (facelift, produced 2008-2011) 1.8 XER (140 hp) represents a mid-range offering within the second generation of the Zafira compact minivan. Introduced as part of a significant facelift for the B-series Zafira, this variant aimed to balance performance, fuel economy, and practicality for family buyers. The Zafira B, built on the GM Delta platform (internally designated as the 2005 model year), was a popular choice in the European market, known for its flexible seating configuration and spacious interior. The 1.8 XER engine, coupled with a five-speed manual transmission, provided a step up in power compared to the base 1.6-liter models, while remaining more affordable than the higher-specification 1.9 CDTi diesel or the 2.2 Direct injection petrol options.
Powertrain & Engine Architecture
The heart of the Zafira B 1.8 XER is the Z18XER engine, a 1.8-liter (1796 cc) inline-four cylinder gasoline engine. This engine belongs to the GM Family 1 engine family, known for its durability and relatively simple design. It features a cast iron block and an aluminum cylinder head, incorporating four valves per cylinder (16 valves total) operated by a dual overhead camshaft (DOHC) configuration. The Z18XER utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports, and is naturally aspirated. The engine produces a maximum power output of 140 hp (104 kW) at 6300 rpm and a peak torque of 175 Nm (129.07 lb-ft) at 3800 rpm. The compression ratio is 10.5:1. The engine oil capacity is 4.5 liters (4.76 US quarts / 3.96 UK quarts), and the cooling system requires 6.1 liters (6.45 US quarts / 5.37 UK quarts) of coolant.
The transmission paired with the 1.8 XER is a five-speed manual gearbox. This transmission is a standard, non-electronic unit, providing a direct and engaging driving experience. The gear ratios are tuned to provide a balance between acceleration and fuel efficiency. While an automatic transmission was available on some Zafira B models, it was not typically offered with the 1.8 XER engine.
Engine Code Specifics
The ‘XER’ designation within the Z18 engine family indicates specific refinements for emissions compliance and improved efficiency. The Z18XER engine meets Euro 5 emission standards, incorporating features like improved catalytic converters and optimized engine management software. This engine code is known for its relative reliability, although regular maintenance, including oil changes and spark plug replacement, is crucial for long-term performance.
Driving Characteristics
The Zafira B 1.8 XER offers a noticeable improvement in performance compared to the lower-powered 1.6-liter variants. While not a sports car, the 140 hp engine provides adequate power for everyday driving, including highway cruising and overtaking maneuvers. The five-speed manual transmission allows drivers to maintain optimal engine speed for efficient acceleration. The power delivery is relatively linear, with a usable torque band from around 2500 rpm. Compared to the 1.9 CDTi diesel, the 1.8 XER lacks the low-end torque of the diesel, requiring more frequent gear changes when climbing hills or carrying a full load. However, the petrol engine offers a smoother and quieter driving experience. The weight of the vehicle (approximately 1503 kg / 3313.55 lbs) does impact acceleration, resulting in a 0-60 mph time of around 10-11 seconds.
Equipment & Trim Levels
The 1.8 XER trim level typically sat in the mid-range of the Zafira B lineup. Standard equipment generally included air conditioning, power steering, electric front windows, a CD/radio system, and ABS brakes. Safety features such as driver and passenger airbags were also standard. Interior upholstery was typically cloth, with a durable and practical design. Optional extras available for this trim included alloy wheels, rear parking sensors, cruise control, and an upgraded audio system. Higher trim levels, such as the Design or SE, added features like automatic climate control, leather upholstery, and more advanced infotainment systems. The Zafira B’s defining feature remained its flexible seating arrangement, with the ability to configure the interior for five or seven passengers, and fold the rear seats flat to maximize cargo space.
Chassis & Braking
The Zafira B 1.8 XER utilizes a MacPherson strut front suspension and a semi-independent torsion beam rear suspension. This suspension setup provides a comfortable ride quality, suitable for family transportation. The torsion beam rear suspension is a cost-effective solution that offers adequate handling characteristics for most driving conditions. The front track is 1488 mm (58.58 in) and the rear track is 1512 mm (59.53 in). The braking system consists of ventilated disc brakes on the front wheels and drum brakes on the rear wheels. ABS (Anti-lock Braking System) is standard, enhancing braking performance and stability. The steering is a rack and pinion system, providing precise and responsive steering feel.
Market Reception & Comparison
The Zafira B 1.8 XER was generally well-received by automotive critics as a practical and versatile family vehicle. Reviewers praised its spacious interior, flexible seating, and comfortable ride. The 1.8-liter engine was considered a good compromise between performance and fuel economy, although some critics noted that it could feel underpowered when fully loaded. Compared to the 1.9 CDTi diesel, the 1.8 XER offered lower running costs in terms of fuel price, but the diesel provided superior fuel economy and torque. The 1.8 XER also offered a smoother and quieter driving experience than the diesel. Fuel consumption figures are rated at 9.6 l/100 km (24.5 US mpg / 29.4 UK mpg) in urban conditions, 5.7 l/100 km (41.3 US mpg / 49.6 UK mpg) on the extra-urban cycle, and 7.2 l/100 km (32.7 US mpg / 39.2 UK mpg) combined.
