Subaru, the auto unit of Fuji Heavy Industries Ltd., added the most U.S. market share of any foreign carmaker last year as the brand long known for quirky all-wheel-drive vehicles continued to win more mass-market fans.

A revamped Forester crossover and new XV Crosstrek wagon helped boost annual U.S. sales for the Fuji unit by 26 percent, matching 2012's gain and ending 2013 with a record 424,683 deliveries.

Subaru's market share rose 0.4 point to 2.7 percent, an improvement topped only by Ford Motor Co.'s 0.45-point increase, according to Autodata Corp.
