Throughout his winning career, the iconic Monza Frame was equipped with many engines and transmissions, mainly from Alfa Romeo but not only. Race records were set with Triumph engines, Ford transmissions, Armstrong-Siddeley Wilson gearboxes, right after the initial and remarkable sport palmares with the Alfa Romeo straight-eight engine.
All these power-train swaps allowed the Monza Frame to compete successfully for more than 30 years, in a continuous adaptation to the regulatory changes and in endless pursuit for absolute performance.
Nowadays the Monza Frame is ready for its most compelling and challenging update: the electrification. The newest regulations in motorsport, the demanding laws on road circulation and the increased attention to the environmental pollution make the electric evolution unavoidable.
It´s now our own responsibility and privilege to deliver to our next generation the magnificence of this 1930´s car project keeping it alive through the changing times and preserving it´s original racing spirit.
Beauty & Power, from now on, come in Silence.
When it comes to performance, one chart is best of all to represent the performance of the car on straights: the Torque Reserve chart.
A restored Alfa Romeo 8c 2300 supercharged engine was benched on a modern facility to extract its Power and Torque data. This is the very starting point to design a proper electric power-train to suit the 1931 Monza Frame.
Electric Power and Torque were then balanced with Range and Mass to come to the best electric installation possible for this car.
A direct comparison of Torque Reserve vs Speed for the two cars shows that up to 100 km/h the two power-trains deliver comparable performances, being the difference limited to less than 15% in favor of the ancient 8c engine fitted with 4 speeds gearbox.
