Traxxas has “updated” their speed demon car, the XO-1 to a 2014 Edition. The Traxxas XO-1 2014 edition appears to be the exact same car you already know of. Castle Creations Mamba Monster Extreme Speed Control, Traxxas Big Block 1650Kv Brushless Motor, TQi 2.4GHz Radio System, Revo-Spec Differentials, Speed-Rated Belted Tires, and of course the 100+ MPH speed claim (if using the Apple Traxxas Link App and 5000mah lipo battery packs). It seems the 2014 Edition of the Traxxas XO-1 comes with a new painted body and Traxxas as removed the two power cell 5,000mAh batteries they once included in the “old” model (part #: 6407). On Tower Hobbies, the new 2014 XO-1 also costs $10.00 more.
