The Renault 18, launched in 1978, was a significant step forward for the French automaker, marking a departure from its previous, more conservative designs. It was the first Renault to utilize a transverse-mounted front engine, a key feature that would define many of its future models. The 18 was available in various body styles, including a 3-door hatchback, a 5-door hatchback, and a 3-door fastback coupe, named the Fuego. This coupe, introduced in 1980, was particularly noteworthy for its aerodynamic design, inspired by the Renault Alpine A310. The Fuego incorporated a sleek, wedge-shaped profile, with a drag coefficient of just 0.34, making it one of the most aerodynamic production cars of its time. The Renault 18 and Fuego were equipped with a range of four-cylinder engines, with displacements ranging from 1.4 liters to 2.0 liters. The engine lineup included both naturally aspirated and turbocharged options, offering a balance of performance and fuel efficiency. The 18 was praised for its comfortable ride and spacious interior, particularly in the five-door hatchback variant. The Fuego, however, was more focused on performance and handling, with a sportier suspension setup and a more engaging driving experience. Both vehicles found success in European markets, with the 18 becoming a popular family car and the Fuego attracting drivers seeking a stylish and sporty coupe. Despite its significant contributions to Renault's success in the 1980s, the 18 was ultimately discontinued in 1986, replaced by the Renault 19. The Fuego, though initially successful, faced stiff competition from other sporty coupes and was phased out in 1989.
