Four-wheel drive
Subaru broke this pattern by introducing a mass-produced four-wheel drive passenger car, after having tested the waters by building a limited series of four-wheel drive FF-1 1300G wagons in 1971. Four-wheel drive was Subaru's most notable feature during the 1970s and 1980s, leading to particularly strong sales in places like Switzerland and Colorado. The Leone competed with the Toyota Corolla, Nissan Sunny, Honda Civic, Mazda Familia, Isuzu Gemini, and the Mitsubishi Lancer. The Leone introduced a Subaru tradition of frameless side windows for all models.
