A rounded rear finish promotes air swirling and creating little eddies, nearly clinging to the physique and including drag. That automotive designers go to the difficulty of aerodynamically sculpting rear mild clusters exhibits the way it’s price making even small enhancements right here.
Particularly with EVs, during which aerodynamics play an even bigger half within the total effectivity than in ICE vehicles, and since extra drag doesn’t simply add gasoline price however charging time too.
It’s such little particulars that the previous A2 doesn’t have. Its door handles stick out, its windscreen wiper sits above the windscreen edge and there’s (very delicate) physique cladding.
Practicality and rules performed their half too. The A2 has slightly lip spoiler on its hatch, which could possibly be extra environment friendly if it have been larger, and will prolong vertically down the perimeters of the automotive too, like those they placed on the again of lorries.
However that will make rear visibility even worse than it’s and will have spoilt the strains of what I feel is a really fairly little automotive. Ditto if the back lights had been sculpted, quite than formed to match the physique: extra environment friendly, much less engaging.
There are issues Audi didn’t do on the time, then, that it might really feel nearly compelled to do immediately, particularly on a automotive marketed, because the A2 was, as technically intelligent and uber-efficient.
