Charbonneaux Ellipsis - 1997
In 1985, Philippe Charbonneaux and Franco Sbarro had collaborated to design a Renault 25 three-box. Twelve years later, they presented their new joint project: the Ellipsis. The Ellipsis was the 7th prototype designed by Philippe Charbonneaux, based on a long-standing idea: an ovoid shape and diamond-shaped wheels.
The Sbarro Ellipsis, along with three older Ellipsis models, is on display at the Musée de l'Automobile in Reims.
Extract from Journal du Nord vaudois, February 27, 1997
"This very special vehicle was
conceived and created in the form of a full-scale model in
1994, by the French designer Philippe Charbonneaux, now in his
eighties, who was present at the inauguration of the Espera
educational center in Pontarlier in September 1995, which
featured, among other projects, the very same model. This car,
now embodied by Espace Sbarro, has a double advantage, in line
with the original concept: highly aerodynamic (like Philippe
Charbonneaux's 1946 Wimille with central drive and
central-rear engine, with an astonishing Cx of 0.21!), the
Ellipsis is egg-shaped with diamond-shaped wheels. This
totally new configuration is designed to deliver exceptional
levels of passive safety. The Ellipsis features a three-seat
cabin with central steering. In the event of a collision, the
vehicle's slender, shark-like silhouette makes it possible to
dodge the obstacle, since the absence of edges and corners on
the car means that the object encountered has virtually no
hold on it. The Ellipsis is thus instantly diverted from its
trajectory, limiting to an unimaginable degree the harmful
consequences that would result from a "traditional" collision.
Powered by a 3.6-liter Porsche Carrera engine and equipped
with a Tiptronic gearbox, the Ellipsis features a large trunk
(due to the vehicle's length, which is due to its ovoid
shape). Weighing in at around 1100 kg, the vehicle's
manoeuvrability enables it to turn on the road at a steering
angle of 160 degrees."
In brief
1- Rhomboidal and ovoid vehicle shape
2- Supposed to offer better protection in the event of frontal impact
3- Philippe Charbonneaux's idea, realized by Espace Sbarro
