If there’s such a thing as a reasonable exotic car, then the R8 is it. This aluminum-intensive beauty offers headroom, outward visibility and quattro foul-weather traction for painless daily use. The standard 4.2L midship-mounted V8 produces 430 horses, while the available V10 borrowed from Lamborghini wails to the tune of 525 or 550 horsepower depending on version. Drivers have the choice of a six-speed manual or the seven-speed S tronic dual-clutch automated manual.
