The high-revving 4.2 liter V8 delivers impressive performance due to the potent combination of the Audi Valvelift System and FSI® direct injection. Both work in concert to deliver a significant competitive advantage: more power combined with greater efficiency. Additionally, both an aluminum block and aluminum head increase efficiency and save weight, increasing handling performance.
