The Speciality Equipment Market Association show, or SEMA as it's better known, is the mecca of automotive modding. A show traditionally dominated by the aftermarket, in recent years car manufacturers have taken to exhibiting their own mad creations.
Ford's main contributions to this year's SEMA show are all based on the Focus,
In amongst the 50 vehicles on display will be four barmy Focus RS and ST concepts, which Ford says "highlight technology and an intelligent balance of power and performance".
The first concept is based on the ST, and is impossible to miss thanks to its bright purple paintwork. It's also bang up-to-date, with a roof-mounted drone. On the performance front, it offers a FullRace turbo kit, performance exhaust, air suspension and upgraded brakes, plus plenty of bodykit additions.
The 'TriAthlete' concept is almost discreet in comparison, with a smoky black finish over the RS bodywork. It also has plenty of upgrades under the skin, plus a fully carbon-kitted interior.
The next concept is called 'Street Performance Packaged for Speed' and features bright yellow paintwork atop white Rotiform wheels and extra carbon bodywork.
Perhaps the most striking concept is the Rally Revival. It's kitted out with bold blue and white paintwork, white OZ Racing wheels and an eye-catching LED light bar across the front.
Under the skin, the Rally Revival RS has been given a full Mountune upgrade, plus plenty of other mods to give the car "better feedback while driving, whether you're cruising local streets or pushing the limits on the track".
Ford's been exhibiting at SEMA for some years now. Last year it displayed a GT4 race car based on the Shelby Mustang GT350, ready to compete in North America's IMSA racing series'.
All four Focus concepts will be on Display at the SEMA show in Las Vegas, from October 31 to November 3.
