The 308 GT4, the Maranello factory's first mid-engined 2+2, was the unique design work of Bertone rather than the customary Pininfarina. By placing the front seats well forward, Bertone made room wîth the 100-inch wheelbase for two children or one sideways-seated adult in the rear, while the compact engine/transaxle package left space behind the engine bay for a 188-liter (6.6 cubic-foot) luggage compartment.
