2013 BMW M5: The twisting highways just south of Seville, Spain, make the 560-hp engine seem a bit excessive for public roads all that power sporadically kicks out the tail end, and triple-digit speeds arrive faster than you can say, "Lo siento, policía!" So we breathed a sigh of relief upon arriving at Ascari Race Resort, where 3.37 miles and 26 turns awaited our Monte Carlo Blue metallic monster. Even with a little morning rain, the M5's Michelin Pilot Super Sports dug into the track's well-kept surfaces.

We nearly forget we were driving more than 4000 pounds of sedan. But what really took us by surprise was how maneuverable the new M5 proved to be, despite its longer wheelbase. Credit the ultraflexible engine, seven cogs to choose from, and a buttoned-down chassis that seems unflappable when pushed near the limit. An active rear differential apportions power to the side that needs it the most, and the hydraulic steering system conveys enough information to inspire confidence.
