Modified performance cars galore.

Ford's stand at the upcoming SEMA show will be a real treat for performance enthusiasts. The Blue Oval will showcase no less than seven modified Mustangs, and at least four tuned Focus hatchbacks.All seven Mustang-based design studies are based on the updated 2018 model. One of the standout models is a wide-bodied GT coupe designed by tuner Roush. It borrows styling cues such as its Grabber Green paint job from the 1970 Boss 429.

Roush has also added window scoops, heat extractors, a splitter, and a full carbon fiber body kit. The cabin receives Recaro bucket seats, a special gauge cluster, and a full roll cage.

The other Mustang-based concepts are built by Tucci Hot Rods, MAD Industries, DeBerti Design, and Air Design, among other tuners. Some are merely head-turning concepts designed for SEMA, while others might eventually spawn limited-edition models or aftermarket body kits. Ford hasn't commented on what the future holds.

Ford is also paying tribute to its historic rally cars with a one-of-a-kind Focus RS named, appropriately, Rally Revival. Its turbocharged 2.3-liter four-cylinder engine benefits from a Mountune kit, a 3" cat-back exhaust, a coilover suspension, and sway bar on both ends.

The Focus ST isn't getting left behind. It receives a boost in power from a Borg Warner turbo and an exhaust from Ford Performance. Handling is improved by an air suspension, an underbody brace, and bigger brakes. Midnight Purple III paint adds a finishing touch to the look.
