The second generation Audi R8 is here or rather its been with us for the past few weeks at least but you will have to wait until 2016 to get your hands on one. The new R8’s exterior  is a striking evolution of the the first but there are some key changes underneath. Its lighter, more efficient and more powerful. The R8 is now offered with just one engine source, the V8 is no more and the normally aspirated V10 will be powering the R8 for the time being. The V10 will be available in two power variants, 540bhp and 610bhp engine specifications. However it hasn’t gone unnoticed to Audi that rivals such as the McLaren 570S and Porsche 911 Turbo offer more power and torque. This is more than enough motivation for Audi to release a turbo powered R8 rival within the next 18 months. Turbo powered petrol engines are making a come back because they are seen as being more efficient than normally aspirated engines and therefore its easier for manufactures to meet emissions targets. Whether the Audi R8 Turbo will retain the V10 and supplement it with a turbo setup remains to be seen. It may well be Audi will either opt for a twin -turbo V6 or V8. Some reports are even citing a 5-cylinder inline twin-turbo arrangement. Audi recently showcased the TT Clubsport which featured a 2.5-litre, 5-cylinder engine with a conventional turbo twinned with an electric supercharger. The unit generated 600bhp and 649Nm of torque. Nevertheless were quite sure the normally aspirated R8 V10 will still offer plenty of power and thrills.
