Compound curvature comprises curves made up of two or more circular arcs of successively shorter or longer radii, joined tangentially without reversal of curvature. The foregoing is illustrated with definitive precision by Helmut Newton’s portrait of perfection above.
The Pirelli calendar is a wonderful institution albeit now somewhat diluted by the dull, shit-boring political correctness which pervades our times! It’s nowhere near as risqué as it once was, always tastefully so in my view.
The image is from the 1985 season, originally published in the ’86 calendar and features a young lady whose specifications more than match the 750bhp, twin-turbo, 1.5 litre Renault EF4B V6 powered Ligier JS25. I’m not sure of the driver but the helmet of Andrea De Cesaris is closer to a color match than those of teammates Jacques Laffitte and Philippe Streiff.
In any event the photo is hardly about the car or driver, what compound curvature, arcs of changing radii and perfect purity of line…
