The Ford Sierra is a mid-size car that was produced by Ford Europe from 1982 to 1993. It was the successor to the Ford Cortina and was marketed in various body styles including a sedan, a 3-door hatchback, a 5-door hatchback, and a station wagon. The Sierra was a significant departure from its predecessor in terms of design and engineering. It featured a new aerodynamically designed body with a distinctive wedge shape, which was a trend in the automotive industry at that time. This design resulted in a more fuel-efficient car with better handling and stability. The Sierra was also available with a range of petrol and diesel engines, including the powerful Cosworth engine in the high-performance RS Cosworth variant. The 1990 Ford Sierra, part of the model's final production run, continued to offer both practicality and performance. This specific year saw the introduction of the 2.0L DOHC 16-valve engine, which was an upgrade over the previous 2.0L engine offering more power and improved fuel efficiency. The 1990 Sierra also benefited from revisions to the suspension and interior, enhancing its comfort and handling further. While the Sierra faced competition from other European models like the Opel Vectra and the Vauxhall Cavalier, it maintained its popularity due to its reliable engine options, spacious interior, and overall affordability. Today, the Ford Sierra is a sought-after classic car, particularly the rare and high-performance RS Cosworth variants. The 1990 Ford Sierra Repair Service Manual provides detailed information and instructions for maintaining and repairing this classic vehicle, ensuring that owners can keep their Sierras running smoothly for years to come.
