The 500 is 11.6 feet long, appending the L added exactly two more feet, and the XL is said to be another six inches longer in the rear overhang to make room for that third row. The Small U.S. Wide (SUSW) platform it sits on will, so it is said, find its way under "a future B-segment Jeep crossover."
While the Fiat 500L is on its way to dealerships this year, the 500XL (if that ends up being its production name) isn't expected to hit showroom floors until later in 2013.
