Audi established a new bar for fast wagons with the RS2 Avant, and the signature color of that model was termed “RS Blue”. Immediately, the vibrant hue was recognizable as the warning sign to other drivers that more lurked under the hood than most normal grocery getters. Audi would continue this trend and signature color with the new quattro GmbH-made S6 Plus a few years later. But in 2001, Audi made the exclusive color a bit more pedestrian by offering it on the B5 S4. Now termed “Nogaro Blue Pearl”, it developed an immediate fan following since then – as now – for most, purchasing either a RS2 or S6 Plus isn’t in the cards. Audi continued the shade on to the B6 platform, where it continued to be the defacto shade of speed until it was discontinued in the B7 chassis. While Audi has recently brought the color back into its lineup, for many the older cars still have a distinctive draw and Nogaro cars typically demand a premium. For some, that premium is heightened even more when the interior was opted with the Nogaro colored Alcantara. Add in Avant and 6-speed to the option list on these cars, and the collective Audi fanboy community draws a sharp breath as lips are bitten and pants decidedly tighten. As a treat, we have two examples to consider – which is more Nogtastic?
