A bigger stick for the soft-spoken supercar, and a price to match.
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 Lambor ghini 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.
