Several tuned iQ small city cars will be exhibited at the 2011 SEMA Show, next week in Las Vegas. Three iQ have been created for the show's Tuner Challenge, with a fourth custom special displaying a radical chop-top look. They are joined at SEMA by further American-market models that have been given ultimate makeovers, plus some of Toyota's latest State-side racing machinery.

Michael Chang, Jon Sibal and Tatsu are the famous tuners who have worked their magic on iQ. Chang has produced the iQ-RS, giving the car the full motorsport treatment: key elements include a carbon fibre body kit, Air Runner suspension, Sparco race seats and Advan Racing wheels.

Sibal Scion iQ RX comes with a complete body kit including front and rear bumpers and side skirts. The car is finished in a subtle matte metallic grey and bronze pearl paint finish. The engine is slightly modified by adding a Nitrous Express injection kit. The car stands on 18" three-piece forged HRE rims. Again, Air Runner suspension sits the car close to the ground.

Tatsu Scion iQ MR is even more brutal. It comes with RWD and customized bodywork featuring new panels from Speciality Cars and 16" Sakura wheels from Axis are fitted.

Pit Boss Cartel iQ is a racing pits support vehicle. Cartel has removed the roof, reduced the size of the doors and fitted tough metal interior panels and carbon fibre seats and trims.

More radical still, this iQ can be controlled by iPad and serves as a mobile WiFi hotspot and power charging station.

The SEMA show opens at the Las Vegas Convention Center on 1 November.
