Vauxhall Zafira B 2.2i 16V (150 Hp)

The Vauxhall Zafira B 2.2i 16V, produced from 2005 to 2008, represented a mid-range offering within the second generation Zafira (B) lineup. Positioned above the base 1.6L and 1.8L models, and below the more powerful 2.0L Turbo and diesel variants, the 2.2i aimed to provide a balance of performance and practicality for family buyers. This Zafira variant was exclusively offered as a five-door minivan with seven-seat configuration, built on the GM Delta platform (internally designated as 1HX0/A3). It was marketed as a versatile vehicle capable of handling both daily commutes and longer family journeys.

Powertrain & Engine Architecture

The heart of the Zafira B 2.2i 16V is the Z22YH engine, a 2.2-liter (2198 cc) inline-four cylinder gasoline engine. This engine belongs to the GM Ecotec family, known for its lightweight construction and relatively efficient design. The engine features a cast iron block with an aluminum cylinder head, incorporating a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration allows for optimized airflow and improved volumetric efficiency. Fuel delivery is managed by a multi-port fuel injection system, providing precise fuel metering for enhanced combustion. The compression ratio is set at 12:1, contributing to the engine’s power output.

While a five-speed manual transmission was standard, the 2.2i was also available with a four-speed automatic transmission. This automatic, often referred to as the 4T40-E, was a common GM unit known for its smooth operation but also for potential reliability concerns with age. The automatic transmission features electronically controlled shifting and torque converter lock-up for improved fuel efficiency at cruising speeds. The engine produces 150 horsepower (112 kW) at 5600 rpm and 215 Nm (158.58 lb-ft) of torque at 4000 rpm. The engine’s power-to-weight ratio is 10.5 kg/hp, and the torque-to-weight ratio is 7.3 kg/Nm.

Fuel Injection and Valvetrain Details

The Z22YH engine utilizes sequential multi-port fuel injection, meaning each cylinder has its own injector that sprays fuel directly into the intake port. This system is controlled by the engine control unit (ECU), which monitors various sensors to determine the optimal fuel delivery based on engine load, speed, and other parameters. The DOHC valvetrain, coupled with four valves per cylinder, allows for efficient cylinder filling and exhaust scavenging, contributing to the engine’s overall performance. The engine’s intake and exhaust ports are designed to maximize airflow, further enhancing its power output.

Driving Characteristics

The Zafira B 2.2i 16V with the automatic transmission offers a comfortable and relatively relaxed driving experience. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 10.6 seconds, while 0-60 mph is achieved in around 10.1 seconds. The top speed is rated at 200 km/h (124.27 mph). Compared to the manual transmission version, the automatic slightly reduces acceleration due to the inherent power loss within the torque converter. However, the automatic provides smoother gear changes and reduces driver fatigue, particularly in urban traffic. The engine delivers adequate power for everyday driving, with sufficient torque for overtaking maneuvers. The four-speed automatic transmission, while functional, can feel somewhat dated compared to more modern transmissions with a greater number of gears. The gear ratios are optimized for a balance of acceleration and fuel economy, but the lack of a higher gear can result in higher engine speeds at highway cruising speeds.

Equipment & Trim Levels

The Zafira B 2.2i 16V was typically offered in a mid-range trim level, often designated as ‘Design’ or ‘Exclusiv’ depending on the specific market. Standard equipment included air conditioning, power windows, central locking, an integrated radio/CD player, and ABS (Anti-lock Braking System). The interior featured cloth upholstery, with a functional and durable dashboard layout. Optional extras included alloy wheels, a sunroof, parking sensors, upgraded audio systems, and leather upholstery. Seven seats were standard, with the rear seats folding flat into the floor to create a large cargo area. The Zafira B was known for its flexible seating arrangements, allowing for a variety of configurations to accommodate passengers and luggage.

Chassis & Braking

The Zafira B 2.2i 16V 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, although it is not particularly sporty. The front brakes are ventilated discs, while the rear brakes are solid discs. The braking system is assisted by ABS, ensuring effective stopping power in various conditions. The steering is rack and pinion, providing precise and responsive handling. The standard tire size is 205/55 R16, mounted on 6.5J x 16 inch steel or alloy wheels. The curb weight of the vehicle is 1570 kg (3461.26 lbs), with a maximum weight of 2135 kg (4706.87 lbs).

Market Reception & Comparison

The Zafira B 2.2i 16V received generally positive reviews from automotive critics. It was praised for its spacious interior, flexible seating arrangements, and comfortable ride. However, the automatic transmission was sometimes criticized for its lack of responsiveness and limited number of gears. Compared to the 1.8L models, the 2.2i offered noticeably improved performance, making it a more suitable choice for drivers who frequently carry passengers or travel long distances. Compared to the 2.0L Turbo, the 2.2i offered a more affordable price point, albeit with less power. Fuel economy was rated at 8.2 l/100 km (28.7 US mpg) combined, which was reasonable for a vehicle of its size and class. Reliability was generally good, although some owners reported issues with the automatic transmission and various electrical components.

Technical Specifications

Legacy

The Zafira B 2.2i 16V, while not the most common variant, remains a reasonably popular choice in the used car market. The Z22YH engine is generally considered to be reliable, provided it has been properly maintained. However, potential buyers should be aware of the potential for issues with the four-speed automatic transmission. Regular servicing, including oil changes and transmission fluid flushes, is crucial for ensuring the longevity of the powertrain. The Zafira B’s spacious interior and flexible seating arrangements continue to appeal to families, making it a practical and affordable option for those seeking a versatile minivan. Parts availability is generally good, as the Zafira B was a widely sold model in Europe. Overall, the 2.2i 16V represents a solid and dependable choice for buyers looking for a comfortable and practical family vehicle.
