The Challenge Stradale is a low production track day focused car based on the 360 Modena. From a handling and braking performance perspective was the equivalent of adding a FHP (Fiorano Handling Pack) to the 360, which was available for V12 models such as the 550,575 or F599 but never separately for the V8’s.
It was inspired by the 360 Modena Challenge racing car series so the focus was primarily on improving its track lapping performance credentials by concentrating on handling, braking and weight reduction characteristics, which are essential in pure racing cars. Ferrari engineers designed the car from the outset with a goal of 20% track day use in mind and 80% road use. With only a small 20 bhp (15 kW) improvement in engine power from the Modena (and boasting an improved power-to-weight ratio) the Challenge Stradale accelerates from 0 to 100 km/h (62 mph) in 4.0 seconds (three tenths faster than a Modena) but bald figures do not paint the full picture. For the enthusiastic driver the differences are truly staggering; genuine systematic improvements were achieved to the setup and feel of the whole car. Throttle response from the digital throttle was ratcheted up and feedback through the steering wheel was enhanced. The responsiveness of the controls, the balance of the chassis, the braking performance and the driver feedback all contribute greatly to the overall driving experience. Thanks to CCM brakes borrowed from the F430, some lower weight parts and a FHP handling pack, the Challenge Stradale was able to claim an impressive 3.5 seconds improvement per lap of its Fiorano circuit compared to the Modena (the target was 2.5 seconds).
In total, the Challenge Stradale is up to 110 kg (243 lb) lighter than the standard Modena if all the lightweight options are specified such as deleted radio, lexan (plexiglass) door window and Alcantara fabric (instead of the leather option). As much as 74 kilograms (207 lb) was taken off on the car by lightening the bumpers, stripping the interior of its sound deadening and carbon mirrors and making the optional Modena carbon seats standard. Resin Transfer Moulding was utilized for the bumpers and skirts, a carry over from the Challenge cars which resulted in lighter bumpers than on the Modena. The engine and transmission weight was slimmed down 11 kg (24 lb) through the use of a smaller, lighter weight sports (yet still stainless steel) exhaust back box and valved exit pipes. The Challenge Stradale also got Brembo carbon ceramic brakes as standard (which later became standard fitment on the F430) which shaved 16 kg off the curb weight and improved handling by reducing unsprung weight and completely eliminating brake fade. Cars fitted with the center console stereo option, sub speaker box behind the seats and glass side windows re-gained approximately 30 kg’s over the best selected options (from a weight perspective).
This 2005 model was number 6 of the 486 made.
