Vauxhall Zafira B 1.6i 16V (105 Hp)

The Vauxhall Zafira B 1.6i 16V, produced from 2005 to 2006, was a key variant within the second generation of the Zafira minivan (designated the Zafira B). Positioned as an entry-level to mid-range offering, it provided a more affordable access point to the Zafira’s versatile seven-seat configuration and flexible interior. This model was built on the GM Delta platform, also known internally as the 1HX0, and aimed at families seeking practicality and space without the higher price tag of more powerful engine options. It represented a significant portion of Zafira B sales during its production run, appealing to buyers prioritizing value and fuel efficiency.

Powertrain & Engine Architecture

The heart of the Zafira B 1.6i 16V is the Z16XEP engine, a 1.6-liter (1598 cc) inline-four cylinder gasoline engine. This engine falls into the GM Family 1 series, known for its relatively simple design and widespread use across various Opel/Vauxhall and other GM vehicles. The engine utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports just before the intake valves. This system, while not as advanced as direct injection, provided reliable and efficient fuel delivery for its time. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to improved breathing and power output.

The Z16XEP produces 105 horsepower (hp) at 6000 rpm and 150 Newton-meters (110.63 lb-ft) of torque at 3900 rpm. The engine’s power-to-liter ratio is 65.7 hp/liter. The engine is transversely mounted in the front of the vehicle. The Zafira B 1.6i 16V was typically paired with a five-speed manual transmission, however, a four-speed automatic transmission was also available, though less common. The automatic transmission was a GM 4T40-E, a widely used four-speed automatic known for its durability and relatively smooth operation. The automatic transmission’s gear ratios were optimized for fuel economy and everyday driving, rather than outright performance.

Engine Specifications

Key engine specifications include a compression ratio of 10.5:1, a cylinder bore of 79 mm (3.11 inches), and a piston stroke of 81.5 mm (3.21 inches). The engine requires 4.5 liters (4.76 US quarts) of engine oil, specified to meet GM’s standards for the period. The cooling system capacity is 6.1 liters (6.45 US quarts).

Driving Characteristics

The Zafira B 1.6i 16V, particularly when equipped with the four-speed automatic transmission, offered a comfortable but unhurried driving experience. Acceleration from 0 to 100 km/h (0-62 mph) took approximately 14.3 seconds, and 0 to 60 mph was achieved in around 13.6 seconds. The top speed was limited to 176 km/h (109.36 mph). The automatic transmission’s gear ratios were spaced to prioritize fuel economy, resulting in a noticeable lack of urgency during acceleration. Compared to the more powerful 2.2-liter Direct Injection petrol or 1.9-liter TDI diesel variants, the 1.6i felt significantly less responsive. However, for everyday commuting and family transport, the engine provided adequate power. The automatic transmission offered smooth gear changes, making it a popular choice for drivers prioritizing ease of use over performance. The relatively low weight of the 1.6i model (1505 kg / 3317.96 lbs kerb weight) helped to mitigate the engine’s power deficit to some extent.

Equipment & Trim Levels

The Zafira B 1.6i 16V typically came with a reasonable level of standard equipment, reflecting its position as an entry-level to mid-range trim. Standard features generally included central locking, power steering, electric front windows, and an adjustable steering column. Interior upholstery was typically cloth, with a functional but basic dashboard layout. Air conditioning was often an optional extra, as were alloy wheels and a CD player. Higher trim levels, such as the Design or Elegance, added features like climate control, upgraded upholstery, and additional safety equipment. The Zafira B’s defining feature – its Flex7 seating system – was standard across all trims, allowing the second and third-row seats to be folded flat or even removed entirely, creating a versatile cargo space. The trunk space ranged from 140 liters (4.94 cu. ft.) with all seats in place to 1820 liters (64.27 cu. ft.) with the rear seats folded.

Chassis & Braking

The Zafira B 1.6i 16V utilized a MacPherson strut front suspension and a torsion beam rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty. The torsion beam rear suspension was a cost-effective solution commonly used in compact and mid-size vehicles. The front brakes were ventilated discs, providing adequate stopping power, while the rear brakes were solid discs. Anti-lock Braking System (ABS) was standard, enhancing safety during emergency braking. The steering system was a rack and pinion type, offering precise and responsive steering. The standard tire size was 205/55 R16, mounted on 6.5J x 16 inch steel or alloy wheels.

Market Reception & Comparison

The Zafira B 1.6i 16V received generally positive reviews, particularly for its practicality, spaciousness, and affordability. Critics praised the Flex7 seating system and the car’s overall versatility. However, the 1.6-liter engine was often criticized for being underpowered, especially when fully loaded with passengers and luggage. Compared to the 2.2-liter petrol and 1.9-liter TDI diesel variants, the 1.6i offered lower performance but significantly better fuel economy. Fuel consumption figures were around 7.3 l/100 km (32.2 US mpg) combined, making it an attractive option for budget-conscious buyers. The 1.6i also tended to be more reliable than the more complex direct injection petrol engines, reducing the risk of expensive repairs. The Euro 4 emission standard was met, reflecting the vehicle’s compliance with contemporary environmental regulations.

Technical Specifications

Legacy

The Zafira B 1.6i 16V, while not the most powerful or exciting variant, proved to be a reliable and practical family vehicle. The Z16XEP engine, when properly maintained, is known for its durability. Today, these vehicles are relatively affordable on the used car market, making them an attractive option for buyers seeking a spacious and versatile minivan on a budget. However, potential buyers should be aware of the age-related issues common to all vehicles of this era, such as corrosion and wear and tear on suspension components. The four-speed automatic transmission, while generally reliable, may exhibit some signs of wear after many years of use. Overall, the Zafira B 1.6i 16V remains a viable option for those prioritizing practicality and affordability over outright performance.
