Hyundai's trifecta of SEMA-bound Genesis Coupes is complete, and the latest tuned, rear-wheel-drive two-door comes courtesy of Street Concepts. Unlike the turbo'd models from RMR and HKS, the Street Concepts Coupe is packing the 3.8-liter V6 fitted with a custom cold-air intake and a Magnaflow exhaust. According to Street Concepts' owner, Shawn Williams, their aim is to "maximize the driving capabilities of the Genesis Coupe while striving for a level of practicality..."

To that end, the only performance mods – outside of aiding the V6's breathing – include a modified suspension, Brembo brakes and 19-inch Volk wheels shod in performance rubber. The exterior benefits from a black camo and "stealth fighter-inspired paint design," along with tinted head and taillights, APR rear wing and custom grille. Inside, carbon fiber trim joins a pair of Cobra seats with black suede accents and an Infinity audio system.

With the Coupes covered, we're waiting to see who Hyundai tapped to tune its three Genesis sedans. We're sure they won't be nearly as entertaining on the track, but a few VIP-styled sedans could do a lot to stoke the image of the Genesis.

Today is the day reservations become available for the Hyundai Genesis Coupe in Korea. To celebrate, Hyundai has released a new commercial which you can watch after the break. Those placing orders now should begin taking possession of their new two-door, rear-wheel drive coupe on September 26. Pricing for the new hotness from Hyundai is very reasonable for the Korean market with a base price of 25,360,000 WON (about U.S. $23,000). Stepping up to the "Stylish Pack" (seriously?) nets you 19-inch rims, a limited slip diff and optional Brembo's for 26,920,000 WON (U.S. $24,500). Well worth it in our estimation. A loaded 3.8-liter V6 Genesis Coupe will go for 33,150,000 WON (U.S. $30,100), which buys you over 300-horsepower and a full leather interior.

Hit the jump for a full rundown of pricing and options for the Coupe in Korea. According to our tipster, the Genesis sedan with the 3.8-liter V6 is selling for about $70K in its home market. This being the case, it's pretty hard to draw any conclusions as to what this means for U.S. Genesis Coupe pricing when it goes on sale sometime in 2009. We can hardly wait.

Hyundai made a huge splash at the New York Auto Show this year with its Genesis Coupe, and it's looking for a repeat performance next month at the SEMA Show in Las Vegas. The Koreans are working with several aftermarket tuners to create special coupes for the tuner show and they just passed along a photo of one of them. This example was created by HKS USA and includes the usual array of body work mods along with plenty of mechanical upgrades. Hyundai hasn't provided details on the engine re-work yet other than noting it's got an HKS GT Turbo package, so presumably this car will use the 2.0L turbo four-cylinder as its starting point. Since the guts of the engine are being beefed up, we can safely assume this thing will be running considerably higher boost than a stock Genesis. Hopefully the HKS Hipermax III fully-adjustable suspension will help make all this power usable on the street as well as the track. The Genesis Coupe may just yet prove to be a very formidable competitor to all those new Mustangs, Camaros and Challengers appearing over the next few months, and we can't wait for our chance to drive one.
