Vauxhall Zafira B 2.0i 16V Turbo OPC (240 Hp)

The Vauxhall Zafira B 2.0i 16V Turbo OPC, produced from 2005 to 2008, represents the high-performance variant of the second-generation Zafira (Zafira B). Positioned as the flagship model within the Zafira B range, the OPC (Opel Performance Center) offered a significantly more potent driving experience compared to the standard Zafira trims, such as the 1.8L and 2.2L models. Built on the GM Delta platform (internally designated as 1HX0), the Zafira B aimed to combine the practicality of a seven-seat minivan with the performance characteristics of a hot hatch. The OPC specifically targeted drivers seeking a sporty and engaging driving experience without sacrificing the versatility of a family vehicle.

Powertrain & Engine Architecture

The heart of the Zafira B OPC is the Z20LEH engine, a 2.0-liter turbocharged inline-four cylinder gasoline engine. This engine is a heavily modified version of the Family 1 engine series used in other Opel/Vauxhall vehicles, but with substantial upgrades to handle the increased power output. Key features include a low-compression ratio of 8.8:1, a Garrett GT2871R turbocharger with an intercooler, and multi-port fuel injection. The engine utilizes a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for improved performance.

Unlike the standard Zafira B models which were often equipped with five-speed manual or automatic transmissions, the OPC exclusively came with a robust six-speed manual transmission. This gearbox was chosen to handle the engine’s 320 Nm (236.02 lb-ft) of torque and provide precise gear changes. The engine’s electronic engine management system carefully controls fuel delivery and ignition timing to maximize power and efficiency. The engine oil capacity is 5 liters (5.28 US qt / 4.4 UK qt), and the recommended oil specification is crucial for maintaining engine health.

Engine Specifications

The Z20LEH engine produces 240 horsepower at 5600 rpm and 320 Nm of torque at 2400 rpm. This translates to a power-to-liter ratio of 120.1 hp/l. The engine’s design prioritizes mid-range torque, providing strong acceleration in everyday driving situations. The turbocharger provides a noticeable boost in power, enhancing the driving experience.

Driving Characteristics

The Zafira B OPC delivers a noticeably different driving experience compared to its more pedestrian siblings. The 240 hp output and six-speed manual transmission allow for brisk acceleration, achieving 0-100 km/h (0-62 mph) in 7.8 seconds and a top speed of 231 km/h (143.54 mph). The chassis was also upgraded with a stiffer suspension setup, including thicker stabilizer bars, to reduce body roll and improve handling. The steering is direct and responsive, providing good feedback to the driver.

Compared to the standard 1.8L Zafira B, the OPC offers significantly more power and torque, resulting in a much quicker and more engaging driving experience. While the 1.8L models focused on fuel efficiency and affordability, the OPC prioritized performance. The six-speed manual transmission allows the driver to keep the engine in its optimal power band, maximizing acceleration. The OPC’s suspension tuning provides a firmer ride than the standard Zafira, but it’s a worthwhile trade-off for the improved handling.

Equipment & Trim Levels

The Zafira B OPC came standard with a comprehensive list of features, reflecting its position as the range-topping model. Standard equipment included sport seats upholstered in a unique cloth/leather combination, air conditioning, an upgraded audio system, alloy wheels (typically 17-inch or 18-inch), and front fog lights. The interior also featured unique OPC badging and trim details.

Optional extras included leather upholstery, a sunroof, parking sensors, and a CD changer. The Zafira B OPC was generally well-equipped, offering a comfortable and refined interior alongside its sporty performance. The seven-seat configuration remained standard, providing the practicality that the Zafira is known for.

Chassis & Braking

The Zafira B OPC’s chassis was modified to handle the increased power and improve handling. The suspension features stiffer springs and dampers, along with thicker stabilizer bars. The front suspension utilizes a spring strut setup, while the rear suspension employs a torsion beam. The braking system was also upgraded with ventilated discs on the front wheels and discs on the rear wheels. Anti-lock braking system (ABS) was standard. The tires are typically 225/40 R18, providing good grip and handling. The curb weight of the Zafira B OPC is 1665 kg (3670.7 lbs), and the maximum weight is 2200 kg (4850.17 lbs).

Market Reception & Comparison

The Zafira B OPC received generally positive reviews from automotive critics. It was praised for its strong performance, engaging handling, and practicality. However, some critics noted that the ride could be firm, and the fuel economy was relatively poor compared to the standard Zafira models. Fuel consumption figures are 13.4 l/100 km (17.6 US mpg / 21.1 UK mpg) urban, 7.4 l/100 km (31.8 US mpg / 38.2 UK mpg) extra urban, and 9.6 l/100 km (24.5 US mpg / 29.4 UK mpg) combined.

Compared to other hot hatches of the time, such as the Ford Focus ST and the Volkswagen Golf GTI, the Zafira B OPC offered a unique combination of performance and practicality. While it may not have been as refined or focused as some of its rivals, it provided a compelling option for drivers who needed a versatile family vehicle that could also deliver a thrilling driving experience. The OPC’s seven-seat configuration set it apart from most other performance cars.

Technical Specifications

Legacy

The Zafira B OPC remains a popular choice among enthusiasts seeking a unique and versatile performance car. The Z20LEH engine is generally considered to be reliable, although regular maintenance is essential. Common issues include turbocharger failure and oil leaks. The six-speed manual transmission is also robust, but clutch wear can be a concern. In the used car market, the Zafira B OPC typically commands a higher price than the standard Zafira B models, reflecting its performance and rarity. The OPC’s combination of practicality, performance, and affordability has ensured its continued appeal to a dedicated following.

The Zafira B OPC represents a significant chapter in Vauxhall/Opel’s performance car history.
