Hyundai thought it would be best to give out tuned version of the Genesis sedan. This is for people who want be rappers, but really can't afford a 60,000$ Lexus LS460. However, because Hyundai are so interested nowadays in performance, so they went off first to customize the mechanics. For starters, then first added a supercharger to the 4.6L Tau V8. Now developing 460hp. But because the new Genesis has active fuel management, it still can be as economical as a V6 engine (although you should try not to turn up the supercharger). In addition to the engine mod, they gave it Baer brakes, a K&N air intake, Magnaflow exhaust and lowering springs. As for visual modifications, this tuned Genesis gets body kit, composite hood, rear roof spoiler and trunk spoiler, black-over-white two toned paint and along with Enkei LS-5 wheels and some decent SEMA tradition rims.
Expect Hyundai to offer such customization like this in the near future.
