Ferrari 275 GTB/6C

Upon its unveiling, the 275 GTB was considered by many to be the finest production Ferrari ever built, combining the pedigree of its road-racing forebears with sufficient creature comforts and a new fully independent rear suspension to produce a superlative grand tourer. The engine was based on the race-proven Colombo V12, now displacing 3,285.7 cc to produce 280 bhp with the standard triple Weber carburettor setup and 300 bhp with the optional and desirable six Weber 40 DNC/3 carbs.

Today’s collectors divide the 275 GTBs into early (short nose) and late (long nose) cars. As with many things Ferrari, the reality is not so simple. While high volume carmakers produced endless quantities of nearly identical cars, Ferraris were still built – to an astonishing degree – by hand. As improvements were devised, they were incorporated into production – often with the very next car. In other cases, features from earlier production would appear on later cars, to the delight of their owners and to the consternation of historians. The changeover to a longer nose design, introduced at the 1965 Paris Salon, was the result of front-end lift at high speed caused by the short-nose setup.

Another common point of differentiation is driveshaft configuration. The earliest cars were fitted with an open Hotchkiss-style normal U-joint and driveshaft setup, the perfect alignment of which was crucial to avoid vibration. Unfortunately, the driveline could become misaligned over time, and sorting it out required skill and special training. Ferrari therefore switched to a driveshaft and constant velocity (CV) joint setup with a centre bearing (referred to as the “interim” setup), which made the alignment process much simpler. Ultimately, Ferrari switched to a torque tube setup.

This car was auctioned off by RM Auctions in May of 2010 at the Grimaldi Forum, Monaco and in October of 2010 at the Battersea Evolution, London.
