When it was released in 2007, the Audi R8 became an instant sensation. But seemingly before the car even turned a wheel the inevitable follow-up question was asked: when is the more-powerful variant coming? After all, Porsche is never content with just a base 911 and with comparisons aplenty between the Stuttgart legend and upstart rookie from Ingolstadt, it was obvious Audi would eventually up its R8 game.
But what engine route would it take? Early reports of a more powerful R8, dubbed the RS8 by some, spoke of it receiving a version of the beastly 575 hp twin-turbo V-10 from the RS6. Those literally went up in flames when a test mule overheated and burned to the ground late last year. The R8 V12 TDI that made its way around the auto show circuit earlier this year with its monstrous 500 hp, 738 lb-ft 5.5L diesel V-12 will for numerous reasons remain a concept - for now. Instead, Audi dug through ready supply of high-power engines to choose from and decided upon 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.
Other than the engine, the two R8s are nearly identical mechanically. Both have the same size same size wheels and tires (235/35ZR19 front, 295/30ZR19 rear) and brakes (15.0-in. front discs and 14.0-in. rears), though carbon-ceramic discs, with a combined weight that is 19.8 lbs lower than conventional discs, will be offered on the R8 5.2. There are some visual differences, however, the most notable being all-LED headlamps, with LEDs serving duty as low beams, high beams, turn signals, and daytime running lights. Each headlamp will be equipped with 54 individual LEDs with a color temperature of 6000 degrees Kelvin, which is closer to the temperature of daylight than the light of halogen or xenon headlamps. Other cosmetic changes include a chrome grille, more pronounced side blades, wider side sills, twin single-pipe exhausts, and a matte aluminum finish for the grilles on the side of the rear window.

The Audi R8 5.2 FSI quattro will make its world bow at next month's 2009 Detroit auto show and when the R8 5.2 is rolled out in Germany in the second quarter of 2009, it will come with a sticker price of 142,400 Euros, or $181,645 at current exchange rates. Though there is no official word yet on the timing of a U.S. release, it's likely the R8 5.2 will come stateside sometime late next year with a hefty premium over the base R8, which presently lists for just under $116,000.
