The latest R8 V10 Plus, with an incredible 449kW and 560Nm from its naturally aspirated 5.2-litre V10, is the most-powerful road car Audi has ever devised. On paper, it's also the quickest. But power and pace comes at a price: almost $390k – $389,616 to be exact – before on-roads or before you even think about ticking any options boxes.
At the other end of heroism scale is the humble A3 1.0 TFSI Sportback. While it's not the smallest or cheapest Audi money can buy, with just 85kW from its one-litre three-cylinder engine, it’s quite possibly the slowest. However, pricing starts from an equally modest $35,900.
That means that, on paper, the quickest Audi money can buy is 11 times more expensive than the slowest.
To find out, we put the pair through 11 wildly different tests to see if the numbers stack up in the supercar's favour. Or whether the little five-door underdog can rise to the occasion and steal thunder from the 10-cylinder poster boy.
