On this episode of Head 2 Head, Motor Trend's Jonny Lieberman pits the 2013 Volvo S60 T6 AWD R-Design against returning contender, the 2013 Audi S4. Before hitting the road, the engine placements of both competing sedans are compared against segment contemporaries such the Cadillac ATS & BMW's 335i. Why? Because while both competitors are AWD, they start life as FWD. As a result, both vehicles have unusual engine placements. A mix of limit testing & canyon carving follows as Jonny provides insight on both cars, examining everything from driving impressions to interior ergonomics. Does Volvo's beefed up S60 have what it takes to dethrone Audi's "sleeper sedan?"
