The Velocity XL is 12 in (310 mm) longer and has a 20 in (510 mm) greater span than the SE.[3] The standard XL has a cruising range of 875 nautical miles (1,620 km; 1,007 mi) and a 75% power cruising speed of 185 knots (213 mph; 343 km/h) air speed.[2][4][5]
The XL is available in both fixed gear (FG) and retractable gear (RG) form and can accommodate either three or four passengers plus a pilot. The five seat versions, the XL-5 and the TXL-RG-5, have a rear bench seat for three rather than the alternative separate pair of seats.[1][2][5][6]
Engines available as kits from the manufacturer for all models are the Lycoming IO-360 of 180 to 200 hp (134 to 149 kW), Lycoming IO-540 of 260 to 300 hp (194 to 224 kW), Continental IO-550 of 310 to 350 hp (231 to 261 kW) and the Franklin 6A350C1 of 205 to 235 hp (153 to 175 kW).[1][2][7] Builders may use these manufacturer kits or design their own engine installations using a variety of other engines of similar power output.

The now-defunct Rocket Racing League utilized a highly modified Velocity XL FG airframe and an Armadillo Aerospace 2,500 pound thrust liquid oxygen (LOX) and ethanol rocket engine in both its Mark-II X-Racer and Mark-III X-Racer demonstration vehicles. The Mark-II utilized a standard fixed-gear Velocity XL airframe, modified for rocket propulsion. The Mark-III airframe was more extensively customized during manufacture, explicitly for rocket racing, with a canopy top, center seat and control stick and other enhancements, in addition to the rocket propulsion added to the Mark-II.[9]
