While the trio of tuned Genesis coupes have garnered their fair share of attention, these three Genesis sedans had a few tricks up their sleeves, beginning with the RKSport model above that benefits from a Hyundai-developed screw-type supercharger mated to the 4.6-liter Tau V8.
With 11 pounds of boost huffed into the bent eight, the RKSport sedan is putting out an estimated 460 horsepower, but with a new cylinder deactivation system, fuel mileage is equivalent to that of the V6-equipped Genesis. Hyundai made it clear that it hasn't made an official decision to offer the supercharger, but expect the cylinder deactivation system to be available in the future.In addition to the engine mods, the RKSport model receives a custom body kit, composite hood, rear roof spoiler and trunk spoiler, along with Enkei LS-5 wheels, Baer brakes, a K&N air intake, Magnaflow exhaust and lowering springs.
Both the RIDES and DUB brought out their Genesis sedans to the show, and you can get up to speed below the fold and peruse the galleries for plenty of live and stock shots.

So now Hyundai has its own S-class as well as an AMG model.
I love the Genesis. My only problem with it was its small for tall drivers and tight for big bodied drivers.
The centerconsole could use a little redesign to make the main buttons look nicer, but pound for pound, this is still the best value you can get in a Luxury car.

Impressive, but particularly impressive because of those fuel economy numbers. Granted, I'm of the opinion that anything less than 35mpg is meh (considering a CR-X was rated 45/50 way back in 1983). But you can't beat 460hp. I'd take one. :-)

The Tau V8 was designed from the start to be forced induction friendly. I think they are going to offer the supercharger but the bigger question is if they will use this world class blown sedan to launch a Hyundai Hi-Po brand

at 460 HP its more than enough for me. Competes with E 550 easily. or the BMW 550i.

Sweeeet.
Give me the grey one with the supercharger.
Actually I don't even need 460 hp, that is overkill for what kind of driving I would do in that thing. It would be more of a daily luxury cruiser, and I don't want to be tempted in using that power.

11lbs of boost, and only 80 hp extra?

@ ambient
My thoughts exactly. There must be something we don't know or they're lying about the amount of added boost.

my guess is its the whp. unless they tuned the crap out of the setup to get a clydesdales amount of torque out of the motor. hopefully it is whp, because if thats the case you'd be comparing 460 whp to around 320 (with a 15% drivetrain loss) hp. A 140 hp gain would sound more like it. Shoot, even if it was ONLY a 80 hp gain, getting the fuel economy up to the v6 level would be good enough for me.

compression was lowered from stocks 11 or 10 to 9 or 10. the engines couldn't handle much more. They kept breaking the engines so they were conservative in only using only 80 more horsepower.

Sweet! Hyundai should make a Sport/RS/R/M-style version of the Genesis along the lines of this.

You must mean "nice Mercedes" (aside from the fact that the Genesis borrowed the C-pillar kink from BMW like many other manufacturers have - Infiniti/Nissan, Lexus, Acura/Honda, etc.) since Lexus totally "ripped-off" Mercedes.

You must mean "nice Benz" since Lexus "ripped-off" Mercedes.

That front grill makes the car more reminiscent of MB than Lexus.
