The Testarossa became Ferrari's flagship model in 1984, replacing the 512BB. Testa Rossa or 'Red Head' refers to the crackle Red cam covers of the late 50's racers of the same name.
Ferrari's intention was to create a more refined, practical supercar than the outgoing BB - more a GT than a road racer - while retaining the high performance required in the flagship car. The Testarossa's most striking feature is undoubtedly its distinctive side slats. Not just a styling feature, they served to protect ingress into the new side mounted radiators. A less popular styling cue was the replacement of the traditional rounded tail lights with a new slatted arrangement.
The Testarossa continued largely unchanged until 1992 when the more powerful, restyled 512TR was introduced.
