Audi used to be the weaker brother within the Volkswagen group, but since the eighties, you can hardly notice that. The Ingolstadt brand has a rich history in racing thanks to their Urquattro, a four-wheel driveline of which Audi is still proud. Audi celebrated its 100th anniversary in 2009. The strongest model in their range is the Audi R8. For those on a smaller budget, there is still the A1, or A3, or A4, or A5.
