Another brand wanted less carbonfibre because of a


different cost target.


“The Huracan is a good example of one that worked.


We are trying to conceive a common platform for


another sports car but can’t say yet whether it will


be successful because there are so many differences


between the brands. My opinion is that, on a super


sports car, having a platform that’s good for everybody


will always be a compromise.”


Maurizio Reggiani, Lamborghini’s 57-year-old R&D


Director, reinforces the impression that Sant’Agata


now has enough sway to nudge compromises its way


with issues like who will lead the Huracan/Audi R8


replacement’s development.


“We have one important mother,” Reggiani says. “She


has allowed us to make this huge investment, achieve


the results we’re now enjoying, and create a dream like


the Urus in a short time.”


Reggiani, an engine man who came to Sant’Agata


in 1994 after six years at Maserati and six at Bugatti,


has links to Lamborghini’s engineering roots: he has


worked with Paolo Stanzani and Gian Paolo Dallara,


Lamborghini’s founding engineering giants. He points


to a treasured photograph signed by Dallara, Stanzani


and designer Marcello Gandini. “These three, as young


men, built the original dreams of Lamborghini,” he


says. “Dallara and Stanzani were innovators; visionaries


who understood what Lamborghini stood for. They


wanted to make the purest incarnation of a super


sports car. Bob Wallace understood how to translate


the sensation of driving a sports car on the road, and


communicate that back to the R&D team.”


Mindful of his legacy, Reggiani is driving


Lamborghini full-tilt into a tech-dense, scientifically


analysed supercar position that includes aeronautical


technology for chassis control, four-wheel steering


that works up to 200mph and simulates shrinking or


stretching the wheelbase, sensors embedded in tyre


rubber, revolutionary aerodynamics, and neurological


research into how drivers react.
He talks enthusiastically about thePiattaforma
Inerziale(inertial platform) vehicle dynamics control
system (see sidebar above) introduced with the Huracan.
“We’ve arrived at a level of performance where we need
to give customers confidence that they can use that
much performance safely. The more you give them that
feeling, the more they love the car. Its fundamental that
they must not be worried about using it.”
Yes, but some testers thought the original Huracan
understeered too much. Reggiani says: “My immediate
response is: what mode are you in? In Strada, which is
biased towards understeer, if you’re not a great driver
you will have great safety because you can enter bends
without the rear moving too much. In Sport, we assume
your skill is better so we give you more tail movement
by adjusting front-to-rear torque. In Corsa, you have
neutrality for optimum speed through a corner.”
Nevertheless, he confirms that Lamborghini did mildly
revise the front-to-rear torque calibration for the
Huracan Spyder to make it more neutral in Strada.
Now there’s the four-wheel steering standard on this
year’s Aventador S. At low speed, the rear wheels turn
in the opposite direction from the fronts to virtually
shorten the wheelbase and boost manoeuvrability. At
speed, the rear wheels turn in parallel with the fronts.
“It’s like elongating the wheelbase by 500mm,” says
Reggiani. “It gives us great stability at high speed.”
Making it work meant long sessions with Pirelli to
sort rear tyres. “We started with the same tyres both
ends but were obliged to develop specific rear P Zeros
that can steer at six degrees.” Next up with Pirelli is
a project to embed micro sensors in tyre rubber to
measure load, angle of load, and temperature related
to handling and speed.
The Aventador S’s more sophisticated and dramatic
nose – which generates 130 percent more downforce


  • rear panels, wing and diffuser are aerodynamically
    focused to increase stability across a wide speed range.

Lamborghini’s Piattaforma Inerzi
dynamics system adopts a data rel
arrangement used in aircraft, but
never before in a production car. Three
accelerometers and three gyroscopes at
the centre of gravity – in the Huracan,
just behind the seats – feed real-time
data about longitudinal acceleration,
roll, pitch and yaw instantaneously
to the ESC, four-wheel-drive, steering
and damper systems. “You have

the impression of being faster, more
consistent,” says R&D Director Maurizio
Reggiani. He says that the system lets
you go “close to the point of no return and
continuously controls, checks and tries
to avoid the car being lost. If you made
a mistake with a Diablo you could only
pray. With Huracan, you can make all
the mistakes you want but – within the
physical limits – the car is able to act and
react to guarantee stability and control.”
