When Volvo introduced the S60 in 2011, the Swedes advertised their mid-sized sedan as the naughtiest Volvo ever thanks to a 300HP turbocharged engine. While I’m sure former “R owners” would disagree, the S60 has met with sales success with over 18,000 units sold so far this year, a 14% increase over last year. In 2012 Volvo added a less powerful FWD model to the mix to cut the price of entry. For 2013 Volvo has further expanded the S60 line by adding a torque vectoring AWD system to the lightest S60. Volvo also tells us they have completely refreshed their T5 engine for 2013 and tweaked the transmission for the naughty Volvo’s first retouch ahead of the rumored 2014 refresh. Huh? Yep, Volvo’s gettin’ down with the yearly refresh. Does that make the T5 AWD the naughtiest Volvo ever? Let’s find out.
