Opel Zafira A (facelift ) 1.6 ecoFLEX (97 Hp) CNG

The Opel Zafira A, particularly the facelifted version introduced in 2003, represents a significant entry in the European compact minivan segment. Marketed primarily in Europe, the Zafira A distinguished itself with its innovative space management system, offering seating for up to seven passengers in a relatively compact footprint. The 1.6 ecoFLEX (97 Hp) CNG variant, produced between 2003 and 2005, was a notable offering, reflecting a growing interest in alternative fuel vehicles and fuel efficiency. This model combined a conventional gasoline engine with a dedicated Compressed Natural Gas (CNG) system, providing a lower-emission option for environmentally conscious buyers.

Opel Zafira A (Facelift 2003) 1.6 ecoFLEX CNG: An Overview

The Zafira A, launched in 1999, was Opel’s first foray into the compact people carrier market. The 2003 facelift brought cosmetic and mechanical updates, enhancing the vehicle’s appeal. The 1.6 ecoFLEX CNG model was specifically designed to appeal to markets with established CNG infrastructure, offering a practical and economical transportation solution. While not officially sold in the United States, the Zafira A’s design and functionality influenced the development of similar vehicles in other markets. It competed with models like the Renault Scenic, Citroën Xsara Picasso, and Volkswagen Touran in Europe.

Engine & Performance

The heart of the Zafira A 1.6 ecoFLEX CNG is a 1.6-liter inline four-cylinder gasoline engine, designated Z16YNG. This engine produces 97 horsepower at 6200 rpm and 140 Nm (103.26 lb.-ft.) of torque at 4200 rpm. The engine is designed to run primarily on CNG, with the gasoline system acting as a backup when CNG is unavailable. The dual-fuel system allows for seamless switching between fuels, ensuring continued operation. The engine features multi-port fuel injection and a naturally aspirated configuration. Performance figures reflect the focus on economy rather than outright speed; acceleration from 0 to 100 km/h (0-62 mph) takes 15.5 seconds, while 0 to 60 mph is achieved in 14.7 seconds. The top speed is limited to 170 km/h (105.63 mph). The power-to-weight ratio is 15.3 kg/Hp, and the torque-to-weight ratio is 10.6 kg/Nm.
