Does one really need an Audi R8 with twin-turbo 536 horse power? No. Do we want one…Yes, yes we certainly do. Heffner Performance released a video this week, chatting up their enhanced Audi R8, which will include a ridiculously giant twin-turbo engine, capable of (an apparent) 536 horses – get along lil doggies!

The 536 rwhp rating is well over 50% higher than a factory-shipped R8. The tuner firm claims that with 100 octane fuel, this car may be able to realize 600 rwhp, and a sub-11 second quarter-mile. Our hearts pitter-patter at hte thought, and cross your fingers Heffner will make it happen.

According to WCF: Last week, we told you about the rumors swirling around the German automaker’s upcoming Frankfurt Motor Show showcase. In addition to the debuts of the new A5 Sportback and new generation A8, we were hearing talk of the R8 Spyder taking a bow side-by-side with an electric R8 concept. The sources we sited include Auto Motor und Sport and L’Automobile.

Audi’s R8 convertible has been confirmed for the Frankfurt show, and will bring along a 420 horse power 4.2-liter V8 or a 5.2-liter V10 with 525 horses. If Audi wants to really impress us, they’ll produce an all electric R8 with the same specs at their V10. But until then we’ll keep hoping for a meaner, greener Audi.
