Volvo is expected to add another XC to its crossover/SUV lineup by the end of 2013.? According to Auto Week magazine, new Volvo CEO Stefan Jacoby wants the smaller car to compete with the upcoming BMW X1, Land Rover Range Rover Evoque and Audi Q3.? In addition, Mercedes-Benz is expected to add a vehicle to the mix, likely called the GLC.? The Volvo would probably be called the XC30 and be derived from the all-wheel-drive platform of the current C30 coupe.?? The magazine speculates there may be two versions, too, a longer wheelbase version for the U.S. and China markets and a shorter one for Europe.
