It turns out Hyundai had one more SEMA special up its sleeve, a car it’s calling the most powerful Veloster Turbo designed for the street. It’s been developed together with tuning firm Fox Marketing and develops a healthy 370 horsepower.

In stock form, the Veloster Turbo’s 1.6-liter four already develops a usable 201 horsepower, but the guys at Fox have gone crazy with a new turbocharger, front-mount intercooler, water/methanol injection system, high-flow exhaust and an ECU retune. This brings output to the aforementioned 370 horsepower, when running on 101-octane performance fuel.

To make sure the car also handles well, it’s been upgraded with fully-adjustable coil-over suspension, a strut brace and sway bars. There are also new brakes consisting of six-piston front calipers with carbon fiber ducting and 13.6-inch wavy-cut rotors. Four-piston calipers are used at the rear.

Exterior modifications give the Veloster Turbo an aggressive demeanor that perfectly complements the engine and chassis upgrades. In the cabin, Fox has added racing seats from Takata, four-point harnesses and custom steel bases.

The car will be presented at the 2013 SEMA show in Las Vegas from November 5. It will be joined by a number of other tuned Hyundais including an EGR Group Veloster Turbo, a Bisimoto Genesis Coupe and a JP Edition Genesis Coupe.
