More than a Lamborghini Huracán with an Audi grille, the R8 remains one of the most spectacular cars out there, regardless of whether you choose the coupe or Spyder convertible. Its naturally aspirated V10 can develop 540 or 610 horsepower depending on whether you opt for the V10 or V10 plus version. Thanks to quattro all-wheel drive and a seven-speed, twin-clutch gearbox, the R8 plus takes just 3.3 seconds for the 0-100 km/h sprint.
