While details about the new #Skunkworks Race Concept will be shared during the unveiling on Nov 1st, the other four concepts present are the Bisimoto "Santa-Fast", nitrous-based Rockstar Santa Fe, the Gurnade Veloster Concept and the Ark Road Racer Elantra Concept.

We've already covered these four during the last month or so, but just to recap, the RWD Bisimoto Santa Fe (or Santa-Fast, if you will) is powered by a flex-fuel turbocharged Hyundai-based 3.9-liter Lambda V6, putting down no fewer than 1,040 HP.

The nitrous-fueled Rockstar Santa Fe on the other hand is more about off-road performance, which is easy to figure out once you glance at its 17" KMC bead-lock wheels and 35" Mickey Thompson Baja Claw tires.

Powering it is a 3.3-liter V6 Hyundai unit, fitted with an AEM cold air intake, Mishimoto cooling system, Magnaflow exhaust and most importantly a nitrous-oxide injection system. Unfortunately no power output figures have been released.

The track-oriented Veloster concept on the other hand couldn't be any more different than these previous two. Gurnade made lots of technical and aesthetic changes to the Veloster, such as adding the ECU tune, ARK Performance cat-back exhaust, 845 Motorsports intercooler, downpipe and cold-air intake, as well as the custom fender flares and grille, carbon fiber spoiler, side sills, vented bumper cover, custom headlights, Cobra Nogaro racing seats, Takata racing harnesses, Pierce Motorsports roll cage plus quite a few other modifications.

Finally, the ARK Performance Road Racer Elantra Concept, is all about using the Elantra's practical yet sporty lines and giving it a sort of alternate personality - one that includes integrated flares, bulging forged racing wheels and new front & rear fascia designs.

Underneath, ARK has fitted the Elantra with a turbo kit, blow-off valve and wastegate, a custom exhaust and a new suspension with coil-over shocks, tower brace and front & rear anti-roll bars.

All five cars, including the new Skunkworks Race Concept, will be on display November 1st at the Last Vegas Convention Center.
