Vauxhall Signum (facelift ) 1.9 CDTI (120 Hp)

The Vauxhall Signum, particularly the facelifted version introduced in 2005, represents an intriguing chapter in the history of British automotive design. Positioned as a hatchback – though often described as a ‘sports hatch’ – the Signum aimed to blend the practicality of a family car with a more dynamic driving experience. While never a high-volume seller, especially outside of Europe, the Signum offered a unique proposition in the mid-size segment, competing with vehicles like the Ford Mondeo and Volkswagen Passat. This article details the 2005-2008 facelifted model equipped with the 1.9 CDTI diesel engine, a popular choice in European markets.

Vauxhall Signum (Facelift 2005) 1.9 CDTI: An Overview

The Signum was initially launched in 2003 as a derivative of the Vauxhall Vectra, sharing its platform but offering a more distinctive and, at the time, innovative interior layout. The 2005 facelift brought significant cosmetic updates, including revised front and rear styling, as well as interior enhancements. The 1.9 CDTI engine, a common rail direct injection diesel, was a key component of the Signum’s appeal, offering a balance of fuel efficiency and reasonable performance. Vauxhall, as a British brand under General Motors ownership, targeted the Signum at buyers seeking a more sophisticated and stylish alternative to traditional family saloons and estates.

Engine & Performance

The heart of the 2005 Vauxhall Signum 1.9 CDTI is a 1.9-liter inline-four cylinder diesel engine, designated the Z19DT. This engine produces 120 horsepower at 3,250 rpm and 280 Nm (206.52 lb.-ft.) of torque at 1,750 rpm. The engine features a turbocharger with an intercooler, enhancing both power and efficiency. The 1.9 CDTI was known for its relatively refined operation for a diesel of its era, and its strong low-end torque made it well-suited for everyday driving. The engine’s power-to-weight ratio is 13.4 kg/Hp, and its torque-to-weight ratio is 5.7 kg/Nm. Performance figures include a maximum speed of 193 km/h (119.92 mph). Fuel economy is a strong point, with combined cycle consumption rated at 5.9 l/100 km (39.9 US mpg, 47.9 UK mpg, 16.9 km/l). CO2 emissions are rated at 159 g/km.

Design & Features

The Signum’s body style is a five-door hatchback, offering a practical and versatile cargo area. The 2005 facelift brought a more contemporary front fascia with a revised grille and headlights, along with updated rear light clusters. Inside, the Signum was notable for its ‘flexibility’ seating arrangement, allowing the rear seats to be folded flat or even removed entirely, creating a large, van-like cargo space. Standard features typically included air conditioning, power windows, and a CD stereo system. Safety features, while not as comprehensive as modern vehicles, included ABS (Anti-lock Braking System) and driver and passenger airbags. The Signum aimed to provide a comfortable and well-equipped interior, with a focus on practicality and versatility. The vehicle’s dimensions are: Length 4651 mm (183.11 in), Width 1798 mm (70.79 in), Height 1466 mm (57.72 in), and Wheelbase 2830 mm (111.42 in). Kerb weight is 1605 kg (3538.42 lbs).

Technical Specifications
