Audi dug through its ready supply of high-power engines for its 2010 Audi {{{R8}}} 5.2 FSI quattro, choosing the naturally-aspirated 5.2L V-10 found in the S6 and S8, modified it for mid-engine duty, increased output to 525 hp at 8000 RPM and 391 lb-ft of torque at 6500 RPM, with redline coming at 8700 RPM. And at 569 lbs, the aluminum V-10 weighs just 68 lbs more than the V-8.
Like the V-8-powered R8, the Audi R8 5.2 FSI quattro will come with either a traditional six-speed manual or R tronic six-speed sequential manual. Regardless of gearbox choice, Audi says the V-10 propels the R8 5.2 from 0-62 mph in 3.9 seconds -- about a half-second drop from the 4.4 second 0-60 claim for the R8 4.2 and squarely in the supercar pantheon. Audi also claims the R8 5.2 achieves an average fuel economy of 17.2 mpg, an impressive figure for a 525 hp supercar
