The strength of the BMW M4 Coupé is evident in every detail.
The stunning Lamborghini Countach - which still looks modern today - was the absolute pinnacle of the razor-edged “piega” (fold) school of design that flourished in the early 1970s - and it was Lamborghini that brought it back with the dramatic Reventon in 2008, taking the cues for its geometric styling from today's 'stealth fighter' military aircraft.
You have only to look at production and concept models such as the Aventador and the Sesto Elemento to know that the piega movement is alive and well and living at Sant'Agata.
But this shape, a conceptual proposal for a future Lamborghini model, comes from a final-year transport design student at the Art Centre College of Design in Pasadena, California called Ondrej Jirec, who says its polygonal surfaces were inspired by the F117 Nighthawk and F22 Raptor jet fighters.
We think he's missing the plot just a little.
The important thing about both those aircraft - and the Aventador, for that matter - is the essential, almost minimalist simplicity of their execution, a purity of line which is deceptively difficult to achieve.
Jirec's proposal, we feel, is a little too busy, although the perfect curve of the sharply-etched, rising waistline from headlight to tailpipe is worthy of Giorgetto Giugiaro himself. Nice try, Ondrej, but no cigar.
We'd welcome your comments on this design.
