Vauxhall Zafira B 1.8i 16V (140 Hp) Automatic

The Vauxhall Zafira B 1.8i 16V Automatic, produced between 2005 and 2008, represented a mid-range offering within the second generation of the Zafira minivan. Part of the larger Zafira B series (built on the GM Delta platform, internally designated as 2005-2012), this variant aimed to balance affordability with a more refined driving experience than the base models, while remaining accessible to buyers who didn’t require the performance of the higher-output engines. It was positioned as a practical family vehicle, emphasizing space, versatility, and ease of use, particularly appealing to those seeking an automatic transmission in the compact MPV segment.

Powertrain & Engine Architecture

The heart of the Zafira B 1.8i 16V Automatic is the Z18XER engine, a 1.8-liter inline-four cylinder gasoline engine. This engine falls under the GM Ecotec family, known for its relatively lightweight construction and focus on fuel efficiency. The Z18XER boasts a displacement of 1796 cc (109.6 cubic inches) and features a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration contributes to a respectable power output of 140 horsepower at 6300 rpm and 175 Nm (129.07 lb-ft) of torque at 3800 rpm.

Fuel delivery is managed by a multi-port fuel injection system, providing precise fuel metering for optimal combustion. The engine utilizes a compression ratio of 10.5:1, striking a balance between performance and fuel economy. 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.

Paired with the Z18XER engine is a five-speed automatic transmission. This transmission, while not known for particularly sporty shifts, provided smooth and convenient gear changes, catering to the target audience who prioritized ease of driving over outright performance. The transmission’s gear ratios were tuned for a blend of acceleration and fuel efficiency, with a focus on providing adequate power for everyday driving situations and highway cruising.

Engine Code Specifics

The Z18XER engine code is crucial for identifying specific components and maintenance requirements. It’s a common engine within the Opel/Vauxhall range of the period, and parts availability is generally good. However, like many engines of this era, it’s susceptible to certain issues, such as coil pack failures and occasional oil leaks. Regular maintenance, including oil changes and spark plug replacements, is vital for ensuring longevity.

Driving Characteristics

The Zafira B 1.8i 16V Automatic delivers a comfortable and predictable driving experience. Acceleration from 0-100 km/h (0-62 mph) takes approximately 12.9 seconds, and 0-60 mph is achieved in around 12.3 seconds. While not particularly quick, this performance is adequate for most daily driving scenarios. The maximum speed is rated at 197 km/h (122.41 mph). The automatic transmission contributes to a relaxed driving style, particularly in urban environments. However, drivers seeking a more engaging experience might find the transmission somewhat sluggish, especially during quick overtaking maneuvers.

Compared to the manual transmission version of the same engine, the automatic typically exhibits slightly reduced fuel economy due to the inherent inefficiencies of the torque converter. It also feels less responsive, as the automatic transmission introduces a delay in power delivery. Compared to the higher-output 2.2 Direct Injection engines, the 1.8i Automatic offers significantly less power and acceleration, but it compensates with improved fuel economy and a lower purchase price.

Equipment & Trim Levels

The Zafira B 1.8i 16V Automatic was typically offered in mid-range trim levels, often designated as ‘Design’ or ‘Exclusiv’ depending on the specific market. Standard equipment generally included air conditioning, power windows, central locking, an integrated radio/CD player, and driver and passenger airbags. The interior upholstery was typically cloth, with options for upgraded materials available. The dashboard layout was functional and straightforward, prioritizing usability over aesthetic flair.

Optional extras commonly included alloy wheels, parking sensors, a sunroof, and upgraded audio systems. Some models also offered features like automatic climate control and leather upholstery. The Zafira B’s defining feature, its Flex7 seating system, was standard on all models, allowing the rear seats to be folded flat or even removed entirely, providing exceptional cargo versatility. The trunk space ranged from 140 liters (4.94 cu. ft.) with all seats in place to a substantial 1820 liters (64.27 cu. ft.) with the rear seats folded.

Chassis & Braking

The Zafira B 1.8i 16V Automatic utilizes a front-wheel-drive layout with a MacPherson strut suspension at the front and a torsion beam suspension at the rear. This suspension setup provides a comfortable ride quality, absorbing bumps and imperfections in the road surface effectively. The front brakes are ventilated discs, offering good stopping power, while the rear brakes are discs. Anti-lock Braking System (ABS) was standard, enhancing safety and stability during emergency braking situations.

The curb weight of the vehicle is 1503 kg (3313.55 lbs), with a maximum permissible weight of 2080 kg (4585.62 lbs). The tires are typically sized 205/55 R16, mounted on 6.5J x 16 inch wheel rims. The steering system is a rack and pinion type, providing precise and responsive steering feel.

Market Reception & Comparison

The Zafira B 1.8i 16V Automatic received generally positive reviews from automotive critics. It was praised for its spacious interior, versatile seating arrangement, and comfortable ride quality. However, some critics noted that the engine felt underpowered, particularly when fully loaded with passengers and luggage. Fuel economy was considered reasonable, with combined fuel consumption figures of around 7.2 l/100 km (32.7 US mpg / 39.2 UK mpg).

Compared to other trims in the Zafira B lineup, the 1.8i Automatic offered a good balance between price and features. It was more affordable than the higher-output 2.2 Direct Injection models, but it provided a more refined driving experience than the base 1.6-liter engines. In terms of reliability, the Zafira B 1.8i Automatic is generally considered to be a dependable vehicle, although owners should be aware of potential issues with coil packs and oil leaks.

Technical Specifications

Legacy

The Zafira B 1.8i 16V Automatic remains a relatively common sight on the used car market. Its reputation for practicality, reliability, and affordability has ensured its continued popularity among budget-conscious buyers. While the engine may not be the most powerful, it is generally considered to be durable and relatively easy to maintain. The automatic transmission, while not particularly sophisticated, has proven to be reasonably reliable. However, potential buyers should be aware of the potential for coil pack failures and oil leaks, and should ensure that the vehicle has been properly maintained. Overall, the Zafira B 1.8i 16V Automatic represents a sensible and practical choice for families seeking a spacious and versatile MPV.
