Modeler’s Guide: Ferrari 250 GTO

When thinking of a front-engined Ferrari racing car, many enthusiasts will immediately think of the 250 GTO. It is the classic example of the Ferrari racing car, and it dominated racing venues from 1962 to 1964. It is also the favorite example of the marque for many people. Fortunately, there are many kits and accessories available for the modeler interested in creating an accurate replica.

History

In 1958 Ferrari introduced the 250 GT Berlinetta.  With this car Ferrari was targeting wealthy customers who wanted to have a dual-purpose car, one they could drive on both road and track.  These original 250 GT, also known as “Long Wheel Base” or LWB evolved into the stunning 250 GT SWB (Short Wheel Base). 

The SWB was also a dual-purpose car, but there were variants whose sole purpose was racing.  There were competition versions developed that offered aluminum coachwork to reduce weight along with engines that were specially built with competition in mind. The SWB plays an important part in the GTO story.

In 1961 Ferrari began development of a new car for GT racing.  Based on the SWB chassis, its coachwork was lower and more aerodynamic, with a kamm tail and a version of the 250 Testarossa engine under the bonnet.

The FIA rules were clear that GT racing cars had to be based upon an existing road car.  Ferrari claimed that the new car, now called the 250 GTO (Gran Turismo Omologato) was simply a development of the SWB.  While this claim was disputed at the time (contemporary accounts state that the GTO was a sports prototype in GT clothing) the FIA accepted Ferrari’s claim and allowed the GTO to compete.

The new 250 GTO was completed in the winter of 1961 and presented to the press at Ferrari’s annual press conference on February 24, 1962.  It made its competition debut at Sebring in the same year, driven by Olivier Gendebien and Phil Hill to 2nd overall and 1st in the GT class.  The GTO proved to be nearly invincible in 1962 and 1963.

For the 1964 season, Ferrari faced new and tough competition from Ford and Carroll Shelby.  Ferrari wanted to homologate the 250LM, and there were a number of 250 GTO either built or rebodied with a new “Series 2” coachwork.  This was a significant change from the original cars.  It had a sleeker nose and more angular roof.  It was hoped that the new coachwork would bridge the gap between the GTO and the new LM.

The GTO remained effective. It won the Daytona Continental on February 16, 1964.  Driven by Phil Hill and Pedro Rodriguez, the GTO was 1st overall with an average speed of 98.2 mph – this despite a blown tire.  GTO’s also took 2nd and 3rd in this race.  The new GTO went on to win a number of races in 1964, but it was becoming clear that an era was coming to a close.  While Ferrari was able to convince the FIA that the GTO was an evolution of the SWB, selling the rear-engined 250LM as an evolution of the GTO was a much harder sale.  The FIA refused to recognize the LM as a GT car, and it had to run in the much more competitive prototype class.

But the GTO had made its mark on racing history.  It is widely regarded as the ultimate expression of the GT car.  Even today, watching these cars run in vintage events make any racing enthusiast sit up and take notice.  Nothing sounds quite like a classic Ferrari V-12 at speed.

For the modeler, there is a choice to be made.  One can simply decide to do a “generic” GTO.  This is the easiest course and no one would question the result.  If the desire is to do a particular car, then research would rule the day.  GTO’s were hand-built, very customized automobiles.  They differed in the details of vents, bug shields, fog lights, emblems, etc. In the case of the Series II GTO’s, there were some interesting differences in how the car’s roof was constructed, with some being smooth and others having an integrated airfoil.  In either case, if the goal is to build an example from a particular race then that car would need to be meticulously researched.
