The Vauxhall Vectra C 1.9 CDTi ECOTEC (120 Hp) is a front-wheel-drive, four-door sedan produced between 2004 and 2005. As a member of the Vectra C generation, it represented Vauxhall’s (and Opel’s, its sister brand) offering in the mid-size family car segment. While not sold in the United States, the Vectra was a significant model in the European market, competing with vehicles like the Ford Mondeo, Volkswagen Passat, and Peugeot 406. The “ECOTEC” designation denoted Vauxhall’s commitment to fuel efficiency and reduced emissions, particularly with the introduction of this diesel variant.
Vauxhall Vectra C 1.9 CDTi ECOTEC: An Overview
The Vectra C, launched in 2002, was a substantial redesign of the Vectra line, moving towards a more modern and refined aesthetic. The 1.9 CDTi model, introduced in 2004, aimed to provide a balance of performance and economy, appealing to drivers seeking a practical and efficient family vehicle. The ECOTEC engine, a 1.9-liter turbocharged diesel, was a key component of this strategy. This model year saw refinements to the engine and drivetrain, solidifying the Vectra C’s position as a competitive offering in its class.
Engine & Performance
The heart of the Vectra C 1.9 CDTi is its 1910 cc (116.56 cu. in.) inline-four cylinder ECOTEC diesel engine. This engine, designated Z19DT, produces 120 horsepower at 3500-4000 rpm and a more substantial 280 Nm (206.52 lb.-ft.) of torque between 2000-2750 rpm. The engine utilizes a turbocharger with an intercooler to enhance power output and efficiency. A diesel commonrail fuel injection system ensures precise fuel delivery, contributing to both performance and reduced emissions. The engine’s power-to-weight ratio is 10.8 kg/Hp, and its torque-to-weight ratio is 4.6 kg/Nm. This translates to a maximum speed of 199 km/h (123.65 mph). The engine is transversely mounted at the front of the vehicle, driving the front wheels through a six-speed manual transmission. Fuel economy figures are respectable for its time, achieving 5.7 l/100 km (41.3 US mpg) on a combined cycle, with 7.4 l/100 km (31.8 US mpg) in urban conditions and 4.7 l/100 km (50 US mpg) on the extra-urban cycle. CO2 emissions are rated at 154 g/km, meeting Euro 4 emission standards.
Design & Features
The Vauxhall Vectra C is a traditional four-door sedan, offering seating for five passengers. Its design, while not overtly sporty, is characterized by clean lines and a relatively spacious interior. The trunk offers a practical 500 liters (17.66 cu. ft.) of space with the rear seats up, expanding to 1050 liters (37.08 cu. ft.) when folded down. 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 of 0.28 contributes to its aerodynamic efficiency. Safety features for the time included ABS (Anti-lock Braking System). The suspension system consists of an independent McPherson strut setup at the front and an independent multi-link suspension at the rear, providing a comfortable ride and reasonable handling characteristics. Ventilated discs are used for the front brakes, while solid discs are employed at the rear.
