Just days before the Festival, the Huayra headed up to Northamptonshire to undertake a fascinating aerodynamic experiment at the Catesby Innovation Centre.
In 2017, after lying abandoned for 50 years, its 2740m-long, 8m-wide former Great Central railway underpass was converted into a wind tunnel.
Instigated by Sergio, a former Brabham and Sauber F1 designer, the trial included engineering students from Oxford Brookes University and ex-Ferrari aerodynamicist Willem Toet.

As a student in the ’60s, Sergio was aware of Pronello’s original wind-tunnel tests and was keen to investigate the Huayra’s innovative ground-effect ideas.
Early in the morning, students carefully attached pressure sensors to the immaculate glassfibre body and, with test equipment crammed into the tight cockpit, the Huayra roared up the historic tunnel’s 1:176 gradient.
Several body configurations were tested, including a long-tail extension.

Sergio is full of enthusiasm for the facility: “It’s a great place to confirm the aerodynamic characteristics of a historic car in a fun and inexpensive way.
“With radiator, gearbox and engine running at proper temperatures, and a smooth surface with no outdoor environmental variables, we collected some fascinating data with phenomenal repeatability.”
Appropriately, the Huayra’s name had been suggested to designer Pronello by an artist friend after seeing his scale model being tested in the wind tunnel at a school of aeronautical engineering run by the Argentine Air Force in Córdoba.
The Sport Prototipo series ended in 1973, but the story of the brutal, front-engined Huayra Pronello Ford lived on
“It’s a stunning car,” enthuses Willem.
“The upper shape is slippery and the flat floor with a diffuser gave it quite an edge.
“It has an expansion ratio that puts it staggeringly close to the maximum downforce.”
From the recorded pressure points distributed around the Huayra’s bodywork, the Catesby test confirmed the effectiveness of Pronello’s ideas.

Keen to make the most of the car’s UK visit, Ricardo also accepted an invitation to the Argentine Embassy.
Sitting on a red carpet, the V8 racer let rip for a special lunchtime demonstration, its roar sounding out around Belgravia’s streets, much to the surprise of residents.
But the highlight of the London gathering was an emotional link-up with the Huayra’s 84-year-old designer for a Q&A.
‘With dramatic streamlined bodies with audacious extensions and precarious aerodynamic wings, these front-engined, V8-powered machines looked more like full-scale slot-cars’
After the cancellation of the Sports Prototipo series, Heriberto Pronello moved away from motorsport into military engineering and industrial robotics.
But in 2009, the maverick designer teamed up with Leonardo Monti for a return to competition when he was enlisted to co-design another Liebre racer to compete in the 2010 Dakar Argentina-Chile rally.
Four decades after his legendary GT racers, the dramatic, lightweight 3-litre off-roader had Pronello’s unmistakable, signature profile.
Frustratingly, this exciting national project, driven by locals Fernando and Carlos Veronesi, ran short of funding and retired early.
