On the 1966 Paris Auto Salon, Ferrari launched the GTB/4 with the brand new Tipo 226 engine. It benefited from quite a lot of upgrades launched into the sequence that have been tried and examined within the 275 competitors fashions. Upgrades included an extended nostril bodywork, a torque tube driveline and an engine able to 300 bhp with a dry sump lubrication system.

GTB/4’s are simply recognized by a hood blister that accommodates the bigger air filter housing. Most vehicles have been bodied in metal, however a number of acquired aluminum our bodies. The chassis was barely modified for an elevated entrance and rear observe. The transfer to the quad cam engine was motivated by Ferruccio Lamborghini who spent a fortune making engines that have been extra radical than Ferrari’s. The quad cam stored Ferrari on tempo, but it surely might be argued that gross sales brochure figures have been the first beneficiary of the GTB/4’s introduction since any precise efficiency enhance was slight.

Pininfarina designed the physique of the 275 GTB/4 which is nearly similar to the 275 GTB, taking an actual professional to identify the variations. The giveaway distinction is that the GTB/4 has a barely totally different bonnet form. It has what Ferrari calls a “slim shallow central bulge operating from entrance to rear”.  Just like the 275 GTB, the automotive was constructed by Scaglietti, usually in metal with aluminum doorways, bonnet, and boot lid, though a number of examples acquired full aluminum our bodies.

New American security rules meant that this mannequin was solely produced for a 12 months and a half, throughout which some 280 have been constructed so it’s extremely uncommon. The GTB/4 was the final incarnation of the 275 and was changed by the 365 GTB/4 Daytona. The mannequin’s rarity, ever rewarding efficiency traits, and traditional beauty have made it one of the celebrated grand touring Ferraris of all time.
