NEW DRIVELINE TECHNOLOGY BEING DEVELOPED FOR FUTURE FERRARI SUPERCARS
One form of technology that will be seen on future Ferrari supercars is the Uniair variable valve system, developed by Centro Ricerche Fiat. Not only beneficial for everyday cars, where fuel economy and emissions are improved, the Uniair system also delivers higher power output per unit volume. Applying the Uniair system to the standard 6.0 litre V12 Enzo engine alone would boost power output to approximately 800bhp. Due to the latest developments in the sector, with the arrival of the Mauro Forghieri developed MF1 supercar on the horizon, and the Bugatti Veyron recording a new top-speed record, a 6.8 litre V12 engine is now also on the cards.
With all of this extra power, Ferrari understand that their current rear-wheel-drive system will not suffice. "As is known, in some conditions, high-performance cars have great difficulty discharging the power from the engine to the road. In recent years, therefore, a number of major car manufacturers have begun marketing high- performance car models with four-wheel drives.
"Besides effectively solving the problem of discharging the power from the engine to the road, such a solution also provides for greatly improving control, road-holding in poor-grip conditions, and therefore intrinsic safety of the vehicle," say Ferrari. "Unfortunately, currently marketed four-wheel-drive car transmissions have the major drawback of being extremely heavy and bulky, thus creating serious design problems in terms of location within the vehicle and weight distribution over the two vehicle axles. The structure of currently marketed transmissions, in fact, is derived directly from that normally employed in off- road vehicles, in which the weight and bulk of the transmission are considered secondary to strength and simplifying construction."
With this approach in mind, Ferrari have developed and patented a four-wheel-drive vehicle transmission, which is more compact and lightweight than those currently used, and which is suitable for use in high-performance cars such as the Enzo replacement. With this technology available, Ferrari will be prepared to take part in what is becoming a new supercar challenge.
