It's a misbadging. There's no reason a test car would be at a dealer lot with the protective white stickers on it.
Because it's what they want? Or until now, there haven't exactly been a lot of diesel station wagons. I agree with SUVs though, sport SUV is an oxymoron.If it were real why would anyone buy a gas station wagon? Station wagons and SUVs are for utility not performance, a diesel just makes more sense.
