One of the few race cars built on the Ferrari 250 is the Ferrari 250 Testa Rossa. In the 1950s and 1960s, the great car served as inspiration for some of the most well-known automobiles. It was aiming to be among the most successful Ferraris of all time, winning several championships during its heyday. The Testa Rossa became one of the most desired automobiles due to its triumphs, stunning design, and limited production. In addition, it was one of the most expensive Ferraris ever built.

The tubular steel frame of the 1957 Testa Rossa 250 was used. Independent, coil springs, unequal-length wishbones, and hydraulic shock absorbers were used in the front suspension. A live axle, coil springs, radius arms, and hydraulic shock absorbers were used in the rear suspension. Drum brakes, a 4-speed plus reverse transmission, worm and sector steering, a 140-liter gasoline tank, 5.50 x 16 front tires, and 6.00 x 16 rear tires were some of the car's other design features. The Testa Rossa also had a two-seater spider body with a 2350 mm wheelbase, 1308 mm front track, 1300 mm rear track, and a dry weight of 800 kg.

While the rare race vehicle with an entire inside may be found, this is not one of them. Instead, the Testa Rossa is an actual race vehicle, even if it is legally road legal due to the laxity of the laws. That implies there isn't even a roof, and the interior is devoid of any unnecessary items. Even yet, high-quality materials were employed, with leather seats and a wood steering wheel being the norm.

The year was 1957, and Ferrari was on the verge of winning the World Championship for Sports Cars for the fourth time in the previous five years, after a tough battle with Maserati and Jaguar.

However, rumours circulated in the paddock that the FIA was about to impose a three-litre engine capacity limit for the 2018 season due to the rising frequency of significant incidents.

When Enzo Ferrari heard the reports, he rallied his top engineers. He insisted that they enhance the current 500 TRC as soon as possible so that it would remain competitive and dominate every race it entered in the coming seasons.

He instructed Carlo Chiti, the main designer, that he needed a dependable automobile and that now was not the time for experimentation or failure.

Chiti, who was also working on the Ferrari 246 F1 racer at the time, was recognised for his creativity and desire to try new things. However, he took a cautious approach, developing a prototype alongside Andrea Fraschetti, one of Ferrari's most gifted engineers, who tragically died during a test drive that year.

They extended the wheelbase of a tubular steel spaceframe chassis taken from a 500 TR by 10 cm to 2.35 meters. It had an independent front suspension system that comes with a coil springs, while the rear axle was initially set up as a solid axle.

The prototype's body was built in a hurry to compete in the Nürburgring 1000 Km event and was based on a 290 MM designed by Scaglietti. A Colombo-designed 3.0-liter V12 from the 250 GT series was chosen to power the new race car; however, it was substantially modified for greater performance.

You may have noticed a period where the 250 did not win at Le Mans. Because of the Aston Martin DBR1 and a specific driver named Carroll Shelby, Ferrari did not win the overall championship in 1959. However, it also won at Spa and the Nurburgring and was widely regarded as the 250's main competitor. As a result, the DB4 would get a somewhat more prominent version of the car's engine, which was why it was always as great.
