Volvo debuts S60L for the Chinese market

If you've tried the Volvo S60, did you get the feeling that it might benefit from a little more legroom in the back? The first-generation S60 and the second-generation S60 are fine automobiles, but if there's one gripe we've heard from owners about their cars, it's that rear-seat legroom could be a tad more generous (on that one day of the year when they have more than two people in the car). For the 2014 model year, Volvo is introducing a long-wheelbase version of the sedan, dubbed the S60L, but it will be available only in the Chinese market where long-wheelbase sedans are "a thing." The S60L will have a wheelbase that is 3.1 inches longer than the standard model, for a total of 112.4 inches, all benefiting rear-seat passengers.
