The further you push into six figures, the harder the case looks for a car with an Audi badge wearing a relatively conventional Audi interior. To be blunt, the R8 Spyder is unfortunately too clearly derived from lesser Audi models.
However, equipment levels are high and residual values — which we’d expect to stay very firm indeed in the short term, because the Spyder sells in smaller numbers than the coupé — are predicted to be as good as those of most rivals.
One presumably does not spend the thick end of £120,000 on a two-seat roadster with very little luggage room while worrying too much about economy.
A touring figure of 24.9mpg is reasonable and the overall average of 16.6mpg is what you could reasonably expect in general use.
