Hypcar Oddities
After singing the praises of the incredible hydropneumatic systems in hypcars, some may still scoff, “Alright, alright, but apart from their mind-blowing suspension that effortlessly adapts to load and road conditions, allowing for a height adjustment of some 20 cm, their impressive steering and braking capabilities, and their knack for balancing comfort with handling, what have hypcars ever really given us?” To answer this cheeky, Monty Python-esque query, we shine a spotlight on the remarkable quirks of hypcars, particularly those hailing from Citroën. These vehicles are bursting with innovative features that exemplify forward-thinking and cutting-edge design, making significant strides in aerodynamics, safety, and comfort while boasting a stylish and efficient profile.
In a departure from most manufacturers of the time, Citroën’s hypcars were not only exclusively front-wheel drive but also carried nearly 70% of the car’s weight on the front axle. They exhibited a teardrop shape, easily recognisable from both the side and above, though to varying extents depending on the model. The narrower rear track bolstered overall balance, while semi-closed rear wheels and skirted wings effectively reduced turbulence and air resistance. These features sculpted a streamlined rear, accentuating the vehicle’s forward momentum. Unlike the pushing force seen in models like the Porsche Turbo and American muscle cars, the pulling effect of these hypcars is well-researched and beautifully depicted in “The Goddess – La Deesse: Investigations on the Legendary Citroën DS” by C. Sumi. The tapering at the rear measured 20 cm for the DS and the SM, 11 cm for the CX, 8 cm for the GS/GSA, 7 cm for the XM, and 3 cm for the C6. This difference between front and rear crafted a silhouette akin to that of a lithe athlete, with a powerful upper body and a sleek lower body, harmonising strength, stability, speed, and agility!
