The Vauxhall Vectra C 2.2i 16V Direct ECOTEC (155 Hp) is a front-wheel-drive, four-door sedan produced by Vauxhall, the British marque of General Motors, between 2004 and 2005. Positioned within the mid-size segment, the Vectra C represented a significant evolution for the model line, offering increased refinement, improved safety features, and a range of modern engines. While not directly sold in the United States, the Vectra C was a popular choice in Europe as a family car and company vehicle, competing with models like the Ford Mondeo and Volkswagen Passat. This particular variant, the 2.2i 16V, was a key offering, balancing performance with reasonable fuel economy.
Vauxhall Vectra C 2.2i: An Overview
The Vectra C, launched in 2002, was the third generation of the Vectra, replacing the B model. It marked a departure in styling and engineering, moving towards a more contemporary and sophisticated design. The 2.2i 16V Direct ECOTEC model, produced from 2004-2005, featured a naturally aspirated, inline-four engine designed for a blend of power and efficiency. The “Direct” in the ECOTEC name refers to the direct ignition system, a technology aimed at improving combustion and reducing emissions. The Vectra C aimed to provide a comfortable and practical driving experience, with a focus on passenger space and a reasonably sized trunk.
Engine & Performance
The heart of the Vectra C 2.2i is the Z22YH 2.2-liter inline-four cylinder ECOTEC engine. This engine produces 155 horsepower at 5600 rpm and 220 Nm (162.26 lb.-ft.) of torque at 3800 rpm. The engine utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration allows for efficient cylinder filling and exhaust scavenging, contributing to the engine’s power output. The engine’s power-to-weight ratio is 8.4 kg/Hp, and the torque-to-weight ratio is 5.9 kg/Nm. The engine is transversely mounted, driving the front wheels through a six-speed manual transmission. This powertrain combination allows the Vectra C 2.2i to achieve a maximum speed of 217 km/h (134.84 mph). Fuel economy figures are rated at 7.5 l/100 km (31.4 US mpg) combined, with 10.3 l/100 km (22.8 US mpg) in urban driving and 5.9 l/100 km (39.9 US mpg) on the extra-urban cycle. The engine meets Euro 4 emission standards, reflecting the environmental regulations in place at the time of its production.
Design & Features
The Vauxhall Vectra C is a traditional four-door sedan with a relatively conservative, yet modern, design for its era. It offers seating for five passengers and a spacious interior. A key feature of the Vectra C was its emphasis on practicality. The trunk offers a minimum capacity of 500 liters (17.66 cu. ft.), expanding to 1050 liters (37.08 cu. ft.) with the rear seats folded down. Safety features included ABS (Anti-lock Braking System) as standard equipment. The vehicle’s dimensions are 4611 mm (181.54 in.) in length, 1798 mm (70.79 in.) in width, and 1460 mm (57.48 in.) in height, with a wheelbase of 2700 mm (106.3 in.). The drag coefficient (Cd) of 0.28 contributes to aerodynamic efficiency. The suspension system consists of an independent McPherson strut setup at the front and an independent multi-link suspension at the rear, providing a balance between ride comfort and handling. Ventilated discs are used for the front brakes, while solid discs are used at the rear.
