The 250 P evolved into a saleable mid-engined racer for the public, the 250 Le Mans. Introduced at Paris in November, 1963, the LM was successful for privately entered racers around the world. Notably, a 250 LM entered by the North American Racing Team won the 1965 24 Hours of Le Mans driven by Jochen Rindt and Masten Gregory, which remains as Ferrari's last overall victory in the endurance classic. This car also is on display at the Indianapolis Motor Speedway Hall of Fame Museum. About 32 models were built in 1964 and 1965, with all but the first few powered by 3.3 L 320 hp (238 kW) engines, though the name did not change with the increase in displacement. A fully independent double wishbone suspension was specified with rack and pinion steering and four wheel disc brakes. Ferrari had intended that the 250 LM be homologated for racing as a Group 3 Grand Touring Car, however in April 1964 the FIA refused to do so as Ferrari had built considerably fewer than the required 100 units. The 250 LM thus had to run as a Prototype until it was homologated as a Group 4 Sports Car for the 1966 season.
The North American Racing Team Ferrari 250 LM that won the 1965 24 Hours of Le Mans is a popular attraction at classic car shows and was on display recently at the 2013 Amelia Island Concours d'Elegance. A 1964 Ferrari 250 LM was auctioned off by Sotheby's in 2013 for a price of $14.3 million to an undisclosed telephone bidder. This bidding smashed the previous price record for this model.
In 1965 , the year of the victory of 250 LM at Le Mans, Pininfarina prepared a special version of this car. The 250 LM Berlinetta Speciale, so it was called, was presented at the Motor Show Geneva the same year. The main differences were the large rear window in plexiglas , covering the engine compartment instead of the existing rear cover plate, the vents on the rear wheel arches, which were covered by a grille and the addition of small beaks bumper chrome . The car adopted the livery of the team NART , a white with a blue stripe.
The 250 LM presented at the Paris Motor Show featured a V12 from 2953.2 cc of displacement , the same used by the 250 GTO and the Red Head . But in the following examples the displacement was increased to 3285.7 cm³, so that some sources erroneously reported his name as 275 Le Mans , following the traditional code designations berlinetta Ferrari. The power was entrusted to 6 carburetors 38DCN of Weber . The engine was mounted longitudinally and centrally located, and the exchange , 5-speed, was also longitudinal and cantilever mounted behind the engine itself. The power was 320 hp .
The frame was trellis tube steel . The suspensions , or front the rear, were double wishbone with independent wheels, the shock absorbers were hydraulic with spring coil.
As already mentioned, the racing career of the Ferrari 250 LM was affected by the non-approval of the Gran Turismo , so the car was registered in Class Prototypes coaches over 3.0 liters (only the car with the chassis no. 5149 of NART, with the engine 3 liter, was recorded under Prototypes coaches within 3.0 liters ), going to confront cars specifically designed for competitions, such as the Ferrari 250 P (and their derivatives), theMaserati Tipo 151 and the Iso Grifo A3C , as well as with other GT not yet approved, such as the Ford GT40 .
Despite this he obtained the first and second place at the 12 Hours of Reims of 1964 and the 24 Hours of Le Mans of 1965 (latest success of Ferrari in the French marathon), the same year won the 500 km of Spa and in ' following year won the 1000 km of Paris . The 24 Hours of Le Mans and the 1966 five 250 LM finished among the top 10, but neither took the podium. The car won the last race in 1967 .
The 250 LM He found a lot of success among the private teams, and even the two cars that won the 24 Hours of Le Mans belonged both to private teams, precisely that came first to the American team NART and that finished second at the Francorchamps Belgian team.
