Opel Zafira B 1.6i 16V ecoFLEX (97 Hp) CNG

The Opel Zafira B 1.6i 16V ecoFLEX (97 Hp) CNG is a compact minivan produced by the German automaker Opel between 2007 and 2008. Part of the second generation of the Zafira, this model distinguished itself through its availability with a compressed natural gas (CNG) powertrain, aimed at offering a more environmentally friendly alternative within the segment. While not officially sold in the United States, the Zafira was a popular choice in Europe, known for its versatility, spacious interior, and innovative seating arrangements. The Zafira B, in general, represented a significant step forward for Opel in terms of design, technology, and overall refinement.

Opel Zafira B: A Focus on Efficiency

The Zafira B, launched in 2005, built upon the success of the original Zafira, introducing a more modern aesthetic and improved functionality. The 1.6i 16V ecoFLEX CNG variant specifically targeted environmentally conscious buyers. The “ecoFLEX” designation indicated Opel’s commitment to fuel efficiency and reduced emissions. This model offered a practical solution for families seeking a seven-seater vehicle with lower running costs, particularly in regions where CNG infrastructure was well-developed. The Zafira B competed with other European compact MPVs like the Renault Scenic, Citroën C4 Picasso, and Volkswagen Touran.

Engine & Performance

The heart of the Zafira B 1.6i 16V ecoFLEX CNG is a 1.6-liter inline four-cylinder engine (Z16YNG) producing 97 horsepower at 6,200 rpm and 133 Nm (98.1 lb-ft) of torque at 4,200 rpm. This engine is designed to run on either gasoline or compressed natural gas, offering drivers the flexibility to switch between fuels depending on availability and cost. The engine utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain. The power-to-weight ratio is 14.5 kg/Hp, equating to 69 Hp/tonne. Performance figures reflect the focus on economy rather than outright speed; acceleration from 0 to 100 km/h (0-62 mph) takes 17.4 seconds, while 0 to 60 mph is achieved in 16.5 seconds. The top speed is limited to 163 km/h (101.28 mph). The engine’s displacement is 1598 cm3 (97.52 cu. in.) with a bore of 79 mm (3.11 in.) and a stroke of 81.5 mm (3.21 in.). Compression ratio is 10.5:1.

Design & Features

The Zafira B is a five-door minivan offering seating for up to seven passengers. Its design prioritized practicality and space utilization. A key feature of the Zafira was its “Flex7” seating system, allowing the second and third-row seats to be folded flat or even removed completely, creating a large, versatile cargo area. The trunk space ranges from a minimum of 140 liters (4.94 cu. ft.) with all seats in place to a maximum of 1820 liters (64.27 cu. ft.) with the rear seats folded. The exterior styling of the Zafira B was more rounded and contemporary compared to its predecessor. Safety features for the time included ABS (Anti-lock Braking System). The vehicle’s dimensions are 4467 mm (175.87 in.) in length, 1801 mm (70.91 in.) in width, and 1645 mm (64.76 in.) in height, with a wheelbase of 2703 mm (106.42 in.). The drag coefficient is 0.31. The front suspension utilizes a spring strut setup, while the rear employs a torsion beam. Brakes are ventilated discs at the front and discs at the rear.
