TheFerrari 250 Testa Rossa, or250 TR, is asports racing car built byFerrari from 1957 to 1961. It was introduced at the end of the 1957 racing season in response to rule changes that enforced a maximumengine displacement of 3 litres for the24 Hours of Le Mans andWorld Sports Car Championship races. The 250 TR was closely related to earlier Ferrari sports cars, sharing many key components with other250 models and the500 TR.[1]
The 250 TR achieved many racing successes, with variations winning 10 World Sports Car Championship races including the24 Hours of Le Mans in 1958, 1960, and 1961, the12 Hours of Sebring in 1958, 1959 and 1961, theTarga Florio in 1958, the1000 Km Buenos Aires in 1958 and 1960 and thePescara 4 Hours in 1961. These results led to World Sports Car Championship constructor's titles for Ferrari in 1958, 1960 and 1961.
The 250 Testa Rossa was initially developed to compete in the1957 World Sportscar Championship racing season, in response to rule changes planned for the upcoming 1958 season that would enforce a maximumengine displacement of 3 litres. The objective was to improve on the existing 4-cylinder 2.0L500 TR/500 TRC Testa Rossa by integrating the more powerfulColombo-designed 3.0L V12 as used in250 GT series. Along with the new engine, Ferrari improved the existing Testa Rossa chassis and bodywork. As with other Ferrari racing cars,Enzo Ferrari demanded absolute reliability from all components, resulting in a somewhat conservative design approach that aimed for endurance racing success through durability rather than overall speed.Carlo Chiti was the chief designer during 250 TR development and his continual experimentation counterbalanced Mr. Ferrari's conservatism and led to the many revisions that kept the car competitive through 1962.[1][4] Other Ferrari engineers had major contributions to the 250 TR, notablyGiotto Bizzarrini, who helped with aerodynamic improvements for the 1961 season,[5] and Andrea Fraschetti, who helped develop the first 250 TR prototype before his 1957 death during a test drive.[4]
The 250 TR was raced and continually developed byScuderia Ferrari from 1957 through 1962. In total, 33 250 TRs of all types were built between 1957 and 1962.[4][6][7][8][9][10][11] Included in this total are 19 "customer versions" of the 250 TR sold to independent racing teams, replacing the 500 TRC for this market. All customer cars hadleft hand drive Scaglietti "pontoon fender" bodies and live rear axles. They did not benefit from the continual improvements to Scuderia Ferrari cars, although many independent teams modified their 250 TRs or purchased ex-Scuderia Ferrari cars in order to stay competitive.[1][12][4]
The 250 Testa Rossa engine was based onColombo-designed 3.0L V12 used in 250 GT road and racing cars.Carlo Chiti and other Ferrari engineers made several modifications to increase the performance of this already proven engine. The starting point was a 1953-style cylinder block with an overall capacity of 2953 cc, a 73 mmbore and 58.8 mmstroke. Six two-barrelWeber 38 DCN carburetors fed the engine, increased from the 3 carburetors typical for 250 GT engines. The cylinder heads usedsingle overhead cams, 2valves per cylinder and helical double-coil valve springs (a first for Ferrari).[13][14][6]
The helical valve springs were much smaller than previously usedtorsion springs, allowing the cylinder heads to be strengthened and secured with 24studs rather than 18 in previous 250 engines. This increased the overall reliability of the engine by improvinghead gasket sealing. One spark plug was used per cylinder and the position was changed from earlier 250 designs, now located outside the engine vee between exhaust ports. This allowed for a better spark position and more efficient combustion. Piston connecting rods were nowmachined fromsteel billet, rather thanforged, which resulted in more stress-resistance at higherRPM.[1] The cam covers were painted bright red, the source of the name "Testa Rossa" (literally, "Red Head"). This tradition and name originated with the 500 TR.[6]
The resulting engine was designated Tipo 128 and generated 300 hp (220 kW) at 7000 rpm. The power/displacement ratio of 100 hp/litre was a particular point of pride for Ferrari, as it demonstrated how Ferrari's engineering prowess could create a competitive engine even under rules restricting displacement. The engineering team improved a well understood, proven design by incorporating new technology and strengthening known weak points. They created an exceptionally durable engine, a massive benefit inendurance racing. Other Ferrari racing cars (250 GTO,250 P) achieved racing success with the same basic engine well into the 1960s, years after the 250 TR chassis was obsolete.
1957–1958 250 TRs used a 4-speedtransmission, followed by a 5-speed transmission in 1959. Customer cars were equipped with a 250 GT-style transmission positioned directly behind the engine, while Scuderia Ferrari team cars sometimes used rear-mountedtransaxles for better weight distribution.[6]
The 250 Testa Rossa used a tubular steel spaceframe chassis, similar to that used in the 500 TR. Compared to the 500 TR, the wheelbase was extended by 10 cm to 2.35 meters. The chassis gained a reputation for durability, as it was designed according to Enzo Ferrari's desire for absolute reliability even at the expense of excess weight.[1][4][13][15]
All 250 TRs usedindependent front suspension withcoil springs. All customer cars hadlive rear axles.[4][6] Pre-1960 factory team cars used either live orde Dion rear axles[4][6] while the 1960 250 TRI60 and 1961 250 TRI61 used independent rear suspension.[1]
1957 and 1958 250 TRs were equipped withdrum brakes on all four wheels. Enzo Ferrari insisted on the use of drum brakes in the early 250 TRs as he believed they were more reliable and predictable in how they faded compared to more powerful but relatively newdisc brakes. Drum brakes were unpopular with drivers as they required tremendous physical exertion to operate, due to lack of servo assist and the extremely hard, long-lasting pads used for endurance races. Despite the extensive air cooling used in the 1958 "pontoon fender"-bodied cars, drum brakes were still subject toheat-induced fade.[4] They were finally replaced withDunlopdisc brakes in all Scuderia Ferrari cars for the 1959 race season.[15]
All 250 TRs had 2-seaterspider bodies, as did the earlier 4-cylinder Testa Rossas. At the time, this was considered the lightest and most aerodynamic configuration for a racing sports car.
The first 250 Testa Rossa prototype (chassis number 0666TR) debuted at the 1957Nürburgring 1000km. This hastily prepared prototype was based on a290 MM chassis and had conventional bodywork byScaglietti very similar to that of the 4-cylinder 500 TR, except for a large hood bulge.[1][16]
For the 1958 250 TR, new bodywork was developed in collaboration between Scaglietti andChiti with several innovations on the previous 4-cylinder Testa Rossa body. Instead of the conventional fully enclosed front end, the new body had a distinctive cut-away nose reminiscent of a Formula 1 car. The protuberant central air intake was now flanked by deep channels and the headlights were set intonacelle- orpontoon-like fenders that enveloped each front wheel. The purpose of this design was to funnel cooling air inwards towards thebrake drums, mitigating the persistent problem ofheat-related fade. The lower body was recessed inwards behind the front wheels in order to vent heat from the brakes and exhaust. The front hood was topped with a large bulge and air intake (forward facing on some cars, reverse facing on others) to provide clearance for the vertically oriented carburetors. The rear bodywork was more conventional, including a tapered fairing behind the driver's head and two small brake lights set into vertical fins.[1][6][13][14]
The distinctive cutaway-nose bodywork of the 1958 cars became the most iconic 250 TR style and was used on all cars sold new to private customers. This resulted in the colloquial name for early Scaglietti-bodied 250 TRs: "pontoon fender." Despite their radical appearance, racing and test runs soon showed that this design generated a significant amount ofaerodynamic drag and high speed instability. This was especially noticeable when competing on high speed courses such as theCircuit de la Sarthe against more aerodynamic cars such as theMaserati Tipo 61 andJaguar D-Type. As a result, the Scaglietti bodywork was soon revised and a wide variety of alternative styles were created from 1958 through 1961. Even during 1958, some Scuderia Ferrari cars were equipped with more conventional bodies in the style of the 1957 prototype.[1][4][6][13][14]
The 250 TR's open interior was simple and utilitarian, lacking the luxury trimmings found in FerrariGT cars. The instrumentation and controls were completely focused around the driver. Like other 1950s and 1960s Ferrari sports cars, 250 TRs were equipped with an open gated shifter and aNardi wooden steering wheel.
The 250 TR was subject to continual iteration and refinement from 1957 to 1961, resulting in numerous differences between individual cars that may or may not coincide with different chassis production dates. As was common with Ferrari racing cars of the 1950s and 1960s, 250 TRs were frequently modified and updated by the Ferrari factory and/or private owners. Bodywork was often changed to improve performance or to repair crash damage. Ferrari historians track these changes with a numbering suffix based on year of production (such as 250 TR61 for a 1961-style car) as well as descriptors such as "Spider Fantuzzi" to denote cars with bodies fabricated by Fantuzzi. Despite thishistoriographical systematization, the low-production, hand-built nature of these cars and their use and modification in period mean that differences are most thoroughly explained in the context of an individual chassis' history.
For the 1959 season, the 250 TR body design was lightly revised byPinin Farina, with fabrication of the bodies handled byFantuzzi. The cutaway nose with pontoon fenders was gone, replaced by a more aerodynamic design that still incorporated many ventilation grilles and air inlets.[1][14][15]
The 1959 250 TR was the first Ferrari sports car to use disc brakes (manufactured by Dunlop). Disc brakes are much less susceptible to heat build-up and fade than drum brakes, so the extra air cooling provided by the 1958 Scaglietti body was no longer necessary.[1][14][15]
A 5-speed transmission mounted directly behind the engine was also introduced in 1959.[1][15]
Dry sump lubrication systems became standard equipment for all 250 TRs in 1960. This allowed the engine to sit lower in the chassis, lowering the car'scenter of mass for improved handling and enabling a lower, more aerodynamic front profile.[13]
Rear independent suspension was introduced to the 250 TR in 1960. The car equipped with independent suspension was designated the 250 TRI60 (chassis 0780TR) and throughout the season raced alongside the 250 TR60 equipped with a conventionalde Dion rear axle.[1][13]
The body of the 250 TR again changed for the 1960 season, primarily due to new regulations requiring a windshield with a vertical height of 25 cm. The new, larger windshield was immediately disliked by drivers, as it was difficult to see over, theplexiglass material could not be effectively cleared by windshield wipers, and the much larger surface area increased drag.[1][13] The excess drag resulted in a top speed of 161 mph (259 km/h) down theMulsanne Straight at Le Mans. In comparison, during the same raceMasten Gregory'sMaserati Tipo 61 reached approximately 175 mph (282 km/h).[5]
1959 cars that were updated to 1960 specification (minus independent rear suspension) are often designated as 250 TR59/60.[15]
All 1961 250 Testa Rossas were designated 250 TRI61 as independent rear suspension was now standard.[1]
Due to high drag and visibility problems with the TR60 body style, Ferrari engineers includingGiotto Bizzarrini and Carlo Chiti were tasked with completely re-designing the 250 TR bodywork for the 1961 racing season. As a result, the new Fantuzzi-built TRI61 body incorporated a number of dramatic changes, informed by new aerodynamic theories and wind-tunnel testing. The windshield now had a more gradual slope and wrapped around both sides of the cockpit to meet the rear bodywork. Instead of the rounded tail with fairing for the driver's head, the TRI61 had a very high rear body that met the trailing edge of the side windows and tapered to a truncated, slightly concaveKamm tail.[5] This bodystyle was called an "open coupe" and was very similar to bodies used onmid-engined Ferrari sports racers such as the 1961246 SP.[17]
The front air inlet was now split into two openings, introducing the distinctive "sharknose" or "nostril" style that was also used on other Ferrari sports racing cars such as the 246 SP and the156 Formula 1 car.[1] This front end styling had first appeared on a trio ofMaserati 250Fs that Fantuzzi re-bodied in 1958 for racer Ross Jensen and team owner Temple Buell[18][19] (son of thearchitect with the same name). Fantuzzi's suggestion that the twin intakes would improve air penetration was confirmed by Chiti's wind tunnel testing, leading to the adoption of this style throughout Ferrari's 1961 racing cars.[18]
During testing of the 250 TRI61, a full-width angled "deflector" panel was installed along the top edge of the rear bodywork. This was initially installed to prevent exhaust fumes from entering the cockpit under deceleration. After testing the prototype with the deflector, driverRichie Ginther commented that high-speed stability seemed to improve with only a slight reduction in top speed, leading to the inclusion of this feature on all 1961 bodies. The Ferrari engineers had in effect created a rearspoiler, well before engineers understood the aerodynamic theory behind them and integrated them into many car designs.[1]
For the 1962 season, Ferrari developed the final iteration of the front-engined Testa Rossa, the 330 TRI/LM (LM standing for Le Mans). The biggest change from the 250 TR was a Tipo 1634.0 Litre Colombo V12 developed from the engine of the400 Superamerica, further improved with Testa Rossa cylinder heads and other modifications seen on 250 TR engines. This engine produced 390 hp (290 kW) at 7500 rpm, significantly more power than the 250-series 3.0L unit. This engine design would be used again in the 1964330 P.
The single 330 TRI/LM (chassis number 0808) was built from a damaged 250 TRI60 (chassis 0780TR). The original chassis was lengthened and a TRI61-style spider body by Fantuzzi was fitted. At the1962 24 Hours of Le Mans, this car was driven byOlivier Gendebien andPhil Hill and became the last front-engine car to win an overall victory at Le Mans.[1][20][21]

The 250 Testa Rossa was raced successfully throughout the late 1950s and early 1960s. Independent teams raced the 250 TR alongside Scuderia Ferrari cars from 1958 on, although the most developed versions of the car were restricted to factory-sanctioned teams only.[14]
250 TRs were extremely competitive during this time, winning 10World Sportscar Championship races including the 1958, 1960, and 196124 Hours of Le Mans,[22][23][24] the 1958, 1959 and 196112 Hours of Sebring,[25][26][27] the1958 Targa Florio,[28] the 1958 and 19601000 km Buenos Aires[29][30] and the 1961 4 hours ofPescara.[31] Notable drivers includedPhil Hill,Olivier Gendebien,Luigi Musso,Peter Collins,Dan Gurney,Wolfgang von Trips andMike Hawthorn, among them.
The excellent results of 250 TRs and Scuderia Ferrari's skilled drivers earned Ferrari the 1958, 1960 and 1961 Constructor's World Sportscar Championship titles.[14]
TheAston Martin DBR1 and thePorsche 718 were the 250 TR's closest competitors during this time. Stirling Moss drove a DBR1 to win first place against strong Ferrari opposition at the1958 1000km Nürburgring,[32] and DBR1s would go on to win over 250 TRs at the 1959 Le Mans, Nürburgring, and Tourist Trophy races, depriving Ferrari of the Constructor's World Championship in 1959.[14][33][34][35]
The Tipo 128Colombo-designed 3.0L V12 developed for the 250 Testa Rossa would continue to be used in Ferrari sports racing cars through the early 1960s. The250 GTO,250 P and250 LM achieved racing success with this engine.[1][13][14]
Experimentation on 250 TR body styles from 1957 through 1962 provided Ferrari engineers with valuable experience in developing both low-drag and stability-promoting aerodynamic bodywork. The 250 GTO,SP sports racers, and250/275/330 P were the immediate beneficiaries of this knowledge.
Ferrari named the1984-1991 Testarossa road car as a homage to the 500 TR and 250 TR. In contrast to the front-engine V12-powered 250 TR, the Testarossa is amid-engine design using aflat-12 engine and was designed as a road-goingsports car, rather than a racer.[36]
The 250 Testa Rossa is one of the most valuable vintage Ferraris (and therefore one of the most valuable cars of any type), due to their low production (33 total including all 250 TR variants), racing success and historical influence. The250 GTO is generally considered to have a greater monetary value, although true market values are difficult to determine due to how seldom either model is sold at auction. 250 TRs are often seen at prestigious auto shows such as thePebble Beach Concours d'Elegance[37][38] and theGoodwood Festival of Speed.[39]
A 1957 250 TR (chassis 0714TR) sold for €9,020,000 at RM Sotheby's 2009Maranello auction.[40][41] The 1957 250 TR prototype (chassis 0666TR) sold for $16.39 million at the 2011Gooding & CoPebble Beach auction.[42][43][44] 250 TR chassis 0704 reportedly sold privately in 2014 for $39.8 million.[45]
Fashion designerRalph Lauren's extensive auto collection contains two 250 TRs, a 1958 Scaglietti-bodied car (chassis 0734TR) and a 1961 250 TR/61 Spider Fantuzzi (chassis 0792TR).[46][47]
The value, performance and historical significance ascribed to the 250 TR have motivated many individuals and companies to create reproduction automobiles. Sold as a "replica", "recreation" or "reproduction", these can vary widely in historical accuracy and sophistication, sometimes using Ferrari engines and chassis or simply attempting to replicate the body style of the original with unrelated mechanical underpinnings.[48][49] Some of these reproductions have been unscrupulously represented as original, factory-built 250 TRs.[50]
As 250 TR values rose, some extremely damaged or destroyed 250 TRs were reconstructed using varying amounts of newly fabricated or non-original components. In at least one instance, this has resulted in a case of disputed identity, whereby multiple reconstructed or reproduced cars lay claim to a particular factory chassis number.[51]
