The 1986 Renault 25 was a mid-size executive car produced by the French automaker Renault from 1984 to 1992. This model marked a significant departure from Renault's previous offerings, aiming for a more upscale and refined image. It was the first Renault to feature a transverse-mounted engine and front-wheel drive, a departure from the rear-wheel drive layout of its predecessors. The 25 was available in a variety of body styles, including a four-door sedan, a five-door hatchback, and a station wagon. Power came from a range of petrol and diesel engines, with the most powerful option being a 2.2-liter turbocharged petrol engine producing 160 horsepower.

The 1986 Renault 25 was praised for its spacious and comfortable interior, as well as its refined driving experience. It was also lauded for its advanced technology for its time, including a digital instrument cluster, an optional ABS system, and a pioneering onboard computer system called "B.I.M.S. (Board Information Management System)." Sadly, the 25's sales figures were not as strong as those of its rivals, which was attributed to its somewhat bland styling and a higher price point compared to competitors. Despite this, the 1986 Renault 25 remains a significant milestone in Renault's history, representing a shift towards sophistication and modern design that paved the way for future models. A 1986 Renault 25 Service and Repair Manual is a vital tool for owners who wish to maintain and repair their vehicles, providing detailed instructions and technical information on every aspect of the car, from basic maintenance tasks to complex engine repairs.
