At its core, the Scion xB is a roomy economy car offered with many accessories for owners to personalize their vehicle. The boxy shape is distinctive and adds considerably to the interior volume and utility. The 158-bhp from the 2.4L I-4 is best harnessed to the standard 5-speed manual, although a 4-speed automatic is available. Anti-lock brakes, traction control and stability control are all standard. Scion vehicles are offered with a low fixed price, but numerous accessories can be purchased from the dealer to personalize the vehicle. Options include not only audio system and wheel upgrades, but also items like LED lighting and trim pieces.

The second generation xB has grown appreciably in size adding almost a foot in length and 3 inches in width. The styling features a smoother, more refined interpretation of its predecessor's boxy shape. Power is now provided by a larger 2.4L four-cylinder rated at 158 hp. The limited edition (2,500 units) xB Release Series 5.0 features Gold Rush Mica paint, a body kit with a spoiler, and a moonroof.
