Longtime auto observers know there’s a fine line between a clean, subtle design and a boring car. What might come as a surprise is that Subaru is the brand currently exploring the liminal zone between nice and narcoleptic. After all, when was the last time Subaru design was accused of understated elegance bordering on the hopelessly anodyne? But Subaru is already abandoning its rough-and-ready, quirkily-styled roots for Audi-junior positioning, and this Hybrid Tourer Concept captures those aspirations brilliantly. Too bad Subaru’s most pressing design challenge is improving its plastic-fantastic interiors.
