On March 12 1947, Enzo Ferrari fired up the 125 S, the first car to bear his name. That test-drive on the streets of Maranello marked the start of modern Ferrari history. The then-modest factory quickly grew into one of the great internationally-renowned Made in Italy icons. Now, exactly 70 years later, on March 12 2017, Ferrari launches its official celebrations for this milestone anniversary.
To coincide with the official start of the celebrations and to commemorate the events of 70 years ago, Ferrari is also releasing a special video featuring a re-enactment of the first 12-cylinder to sport the Cavallino Rampante on its bonnet, the 125 S, driving through the factory gates on Via Abetone Inferiore and, in doing so, symbolically passing the baton of the Ferrari legacy to the LaFerrari Aperta.
The 6,262 cc V12 is the most powerful naturally-aspirated engine ever sported by a road-going Ferrari. It punches out 800 horsepower and spins to 9,250 rpm, to deliver absolutely extraordinary performance, driving thrills and an unmistakable Ferrari sound. These unprecedented results are the product of meticulous honing of the engine’s volumetric, mechanical and combustion efficiency.
To boost volumetric efficiency, the V12 employs continuously variable-length intakes – a mainstay in F1 engine technology until banned by rule changes – which optimise performance as a function of engine speed. Similarly, the torque and power curves are optimised across the rev range. The hybrid powertrain generates total torque in excess of 900 Nm: the instantaneous torque from the electric motor is employed at lower revs and V12 engine power and torque is optimised at higher revs. The V12’s peak torque of 700 Nm is, in fact, developed at 6,750 rpm.
Additionally, the entire intake system – from the dynamic air intakes on the top of the rear wheelarches to the intake plenum – was designed to maximise internal fluid-dynamics. The engine also boasts a very high 13.5:1 compression ratio for maximum combustion chamber efficiency.
The engine’s soundtrack plays a huge role in its emotional impact: meticulous tuning has resulted in a full, harmonious sound that’s more intoxicating than ever. The equal-length 6-into-1 exhaust system was hydroformed using Inconel as in F1 to help keep overall weight down with the additional benefit of very high temperature and stress resistance characteristics.
