How many motorsport-related companies would claim that they are faster than a winged object? Would anybody in the car industry challenge Red Bull’s strapline that it “gives you wings”?
This is just what an American user did, with a lawsuit which forced the drinks’ giant to settle out of court for $13m (http://www.telegraph.co.uk/news/worldnews/northamerica/usa/11155731/13m-lawsuit-proves-Red-Bull-doesnt-give-you-wings.html).
Manufacturers will probably be a little more wary of marketing puffery. Just as well that classic racers usually carry famous and heritage-legitimate colours and logos… though one doesn’t expect Martini to claim that drink-driving increases one’s performance.
