By making available an R8 with a monster 525-hp V-10 engine—complementing the 420-hp V-8 model that was introduced two years ago—Audi has elevated its exotic-looking two-seater from “almost-a-supercar” status to a true competitor in the high-performance realm above mere sports cars. The 105-hp increase comes from a 5.2-liter, direct-injection V-10 that is virtually identical to the engine found in the Lamborghini Gallardo LP560-4. Unique engine programming and intake and exhaust systems are the chief differences in the Audi engine over the Italian job, although both engines are made in the same plant in Hungary.
We’re told that the V-10 weighs just 68 pounds more than the V-8, and that fuel economy with the bigger engine will worsen by only 1 mpg. Output is listed by Audi at 525 horsepower and 391 pound-feet of torque, 27 horses and seven pound-feet fewer than in the Lambo, but we suspect some of that difference is simply marketing.
