Red Ferrari Daytona Gr.4 from 1971. V12, 402 HP, 4.3 L
The Ferrari Daytona, officially designated the Ferrari 365 GTB/4, is a two-seat grand tourer by Ferrari from 1968 to 1973. It was introduced at the Paris Auto Salon in 1968 to replace the 275 GTB/4, and featured the 275’s Colombo V12 bored-out to 4,390 cc (4.4 L; 267.9 cu in). It was offered in berlinetta and spyder forms.
The Daytona was succeeded by the mid-engined 365 GT4 Berlinetta Boxer in 1973.
The unofficial Daytona name is reported to have been applied by the media rather than Ferrari and commemorates Ferrari’s 1-2-3 finish in the February 1967 24 Hours of Daytona with a 330 P3/4, a 330 P4 and a 412 P.
To this day, Ferrari itself only rarely refers to the 365 as the “Daytona”, and refers to it as an “unofficial” name.
Unlike Lamborghini’s then-new, mid-engined Miura, the Daytona was a traditional front-engined, rear-drive car.
The engine, known as the Tipo 251 and developed from the earlier Colombo V12 with a 60° bank angle used in the 275 GTB/4, was a DOHC 2 valves per cylinder 4,390 cc (4.4 L; 267.9 cu in), 365 cc (22.3 cu in) per cylinder, bore x stroke 81 mm × 71 mm (3.19 in × 2.80 in), featuring 6X2 barrel 40 DCN/20 Weber carburetors (40 mm Solex twin carburettors were used alternatively).
At a compression ratio of 9.3:1, it produced 259 kW (352 PS; 347 hp) at 7500 rpm and a maximum torque of 431 N⋅m; 318 lbf⋅ft (44 kg⋅m) at 5500 rpm, could reach 280 km/h (174 mph). 0-60 mph (97 km/h) acceleration was just 5.4 seconds.
For the American version, slight modifications were made – the compression ratio was reduced to 8.8:1 and the exhaust system was equipped with a large central silencer, necessitating visible alterations to the primary pipes.
The five-speed manual transmission (of the transaxle concept) was mounted in the rear for optimal weight distribution, and a four-wheel independent suspension featured wishbones and coil springs.
