We're big fans of the Hyundai Genesis Coupe here at Autoblog. We're also fans of vehicles that find ways to make our driving experience more exciting in any way possible. And while it would be nice to see Hyundai plop its 5.0-liter V8 engine under the hood of the Genesis coupe, there is little chance of that ever happening. (Probably for good reason, too.) Still, that doesn't mean more power can't be had, and spy photographers have captured a possible solution lurking under the hood of a Genesis prototype.

It looks like Hyundai is simply going to stick with its 3.8-liter V6 as the range-topping engine, albeit, with a bit of supercharged force added on. What you are looking at could very well be a Hyundai Genesis Coupe R-Spec that's indeed fitting of its extra nomenclature. The supercharger should help push the standard 3.8-liter output of 306 horsepower (333 hp in the 2012 Genesis sedan) up closer to a figure that will have Mustang GT drivers checking their mirrors.

      What is this "good reason" for not putting the 5.0L in there? This car is a direct competitor to the Mustang, not just the 370Z.

        The "good reason" is that the 5.0 simply doesn't fit without a major redesign to the frame and engine mounts. I have a 3.8 Gen Coupe currently, and the 3.8 takes up the entirety of the engine bay...there's really no space left over.

        The good reason is that the V8 won't fit, period. Hyundai has already explained this.

        It's a direct competitor to the 370Z. It's the same size, around the same weight, and almost the same power. The Mustang is a much larger car compared to the Genesis Coupe. Also, the 5.0 won't fit in there. That's why.

          Pretty much everything you said was wrong. You ever seen a GC? It is the size of a mustang not a 370Z. I think you are getting it confused with a tibby.

      Oh man, i don't usually bother to comment on articles. Because quite simply, I have a life and am not going to type an essay like some if you who are all apparently car pros on a cellphone or keyboard. But wow, half of you trash the Genesis and are getting all your facts wrong about the car. I have the 2.0turbo, fully tuned and modded, paid abiut 24k for the car, amd with 7k put into my car (including cosmetic enhancements), im putting down more hp to the wheel than the 412 (so really, lets say 350-370whp) of the mustang. And shocking, muscle car enthusiasts disregarding an import? Wow, be proud of your heritage, and your racing titles. Because on the street, as another guy in a Z06 told me..."I just spent 90k on my Z06, not only did u almost keep up with me, but my wife just told me she likes your car more...". Ohh man, I wish I could see your faces at the track when I blow by you. Be good guys, and do some research before wasting your lives trolling the internet next time. Thanks.

        LOL @ "honey, that guy's genesis is way better than your corvette." No disrespect, but no one in their right mind is going to pick a genesis over a corvette if money is no option for either one. I've driven both and the corvette is much more fun. The corvette is simply an entirely different experience at a different level of life. Its the type of car you can take to the track (if you were so inclined) and then take on a country road afterward to Napa to get some wine. I mean really, why would you buy a "90K" vehicle to go around doing curbside launches from stoplights? Those guys really don't care about that. That being said, the genny is a fantastic car, and hyundai is going gangbusters. They definitely deserve all the credit they are getting. But let's maintain a sense of reality here.... And by the way, your "essay" was pretty long. You're doing the exact same thing you are mocking. I tried to work with what you were saying through the modding, but you lost me at the "wife" part. Thanks for coming out.

        Once you start talking about modified versus stock, the argument becomes pointless. You could have bought a Mustang GT and a FRPP supercharger and be making 640HP and still be enjoying a complete factory warranty.

          I wasn't actually talking modified vs stock, I know comparing them is a crapshoot; that was just an anecdote that around 300 hp is fine by me. I was specifically asking about the effects of mods on your warranty. I'm aware of the Magnuson-Moss Warranty Act of 1975, but I also know dealers often illegally claim that modifying has voided the warranty. As I understand it, legally, they must prove that the modified part caused the failure, otherwise the warranty stands. Getting them to even try to do that can be a hassle, and getting them to uphold the warranty may require a lawyer. I was just asking about the experience people with modded Genesis Coupes have had when it comes to warranty issues. I know this is almost completely dealership dependent. But the two Hyundai dealers in my city are owned by one owner and have a terrible reputation (charging 4-5K above MSRP when the coupe came out, as well as terrible service—both customer and car). I'd just like to know what kind of experience others have had before I buy a car specifically to mod it.

          oren has it right. it's not hard to tune a turbo to power way above the factory tune. that doesn't mean it will last, and least of all, gg warranty.

          It's just cheaper to mod the 2.0 Turbo.... I traded my 32 valve Cobra in for my 2006 Evo IX with AWD and the 2.0T making roughly 300hp stock. It was cheaper to bolt on power to the 2.0 compared to my 4.6 V8. The V8 requires a lot of cash dropped at one time to be fast. Supercharger (3K+) engine rebuild (3K+) where as the Evo requires a few hundred here and there to build up to the same power. $600 exhaust, $80 fuel pump, $300 injectors, $300 tune, etc. After each iteration on the Evo I get more power. After gears and an intake the V8 is pretty much done receiving power. Cams are quite expensive and provide little gains naturally aspirated. After all that the Evo still has AWD, way better suspension, and mine is easily producing 400hp on the stock motor without so much as lifting a valve cover or swapping a turbo. All stock with some bolt ons.... I never spent more than $600 in one sitting, waiting a few weeks between each mod. Never could do that with my Cobra, as much as I liked that car.

        How much of your warranty did you have to void to get that done? And how much will having that much boost effect the lifetime of the engine block? I'm all for the Genesis, and the Mustang; I just don't know how I feel about modding that 2.0T. And once it gets DI next year it be powerful enough for my tastes unmodded—in a car that light, hp in the high 200's is fine by me.

        Sorry.. but I have an MR2 that will blow by you multiple times on the track every single day of the week. My car is putting down 150whp, gets 35mpg and will spank you on the track every single day. (Track DOESN'T equal Drag Strip). My car cost + upgrades = $13k. So basically I saved $19,000 and can still beat you. Sucks for you. I also have a convertible so I drop the top whenever it's nice. If you want to do that, my buddy has a used Supra that he paid 20k for and has about 10k into that's putting down over 600hp and will laugh at you on the drag strip. Genesis is a nice car. I wouldn't but a brand new car then mod it though, that's just stupid. That's like finding a girl you think is hot and saying "go get some plastic surgery because you're not good enough". Why didn't you get find a better looking girl to begin with?

      That car win never, ever be able to compete with a Mustang. It does not matter what it weights, how fast it is or how well it handles. It is about heritage, class and prestige. The Genesis is an appliance with a supercharger. Built for Civic SI kids that finally realized that FWD and no torque VTEC sucks. I don’t even like Ford and I see this as a non comparison.

        Okay, the heritage part I'll give you, but prestige and class?? Haha, we're talking about a Mustang, not an Aston Martin. A Mustang screams class about as much as a double wide mobile home. Who are you trying to kid??

          @ Sean. The Mustang GT is NOT 600 pounds heavier. Mustang GT -3658 pounds Genesis Coupe track - 3389 That's only a 268 pounds difference

          completely disagree. i've driven a mustang gt (new one with 5.0), shelby (new one with 550hp) and V6 track genny. of all of them, the genny was by far the most enjoyable to drive. it wasn't as fast as the shelby or the GT, obviously, but it was much more composed around turns. it's also about 600 lbs lighter than the GT mustang.

      I want one. But busy checking my mirrors Jeff? Don't think so. Doubt I'd even recognize it in my mirrors as it's not all that distinguishable. Besides, I'm too busy watching the dumb blonde secretary half a car length behind me putting on her lipstick and chatting on away her bluetooth. And up front I'm watching the guy squeezzzzing in front of me because now he's gonna be 1/2 second closer to getting to work. He must love his work. Oh, forgot to mention I'm watching the trooper in the median pointing his Laser at me because I'm doing all of 9 over. By the way, I put on MY lipstick at home and drink a big cup of STFU before I head to work.

      Meh. never really liked the look of this thing. Would rather get a 370z which looks 10x better inside and out and goes better too.

        • 3 Years Ago
        @miketim1
        the z might go better, and it's also lighter. won't deny any of that. but the z looks like an angry catfish. i love the wheels they come with, but what is up with that giant ass? can't see anything behind you either. the Z interior is also a bit boy racer, with the orange suede on certain trim levels.

          Plus the fact that you may be able to get the supercharged Genesis Coupe for the price of a base 370Z if they stick it on the R-Spec with a 10 yr warranty

      Some Korean rice is getting an extra kick!! Honda might need to kick up the wasabi sauce since Hyundai seems to be the new king of Asia. Hyundai is no suprise to me on their track to become a world class manufactor. Seen it years ago with their engineering. Since the design department finally caught up, let the asian wars begin! I still would buy a blown ford first, sorry!!

      I really didn't think lack of HP was the Gen Coupe's main problem. Lack of image is this car's main problem. I have seen maybe a 1/2 dozen of these since they came out and they already look kind of dated. There are no commercials/ads for them, and few people outside of car enthusiasts really know about them. The exterior styling is a little bland (but apparently its going to get all kinds of worse if those recent spy shots are true). The interior is even more bland and I think looks a generation behind the rest of Hyundai's interiors. Handling-wise and fun-to-drive categories, this car seems to rank mediocre, at best. More power isn't going to solve any of those issues, so its nice that they haven't thrown in the towel, but they better be doing more then upping the HP count.

      This is a gift from Hyundai to placate current owners (like myself) for screwing up the 2013 refresh. Gencoupe.com forums are saying that "insiders" at the Hyundai R&D facility in southern CA said that the Supercharged 3.8 is pushing well north of 450hp, but will be rated at around 430hp when its released at SEMA.

        So wait a minute, is this a SEMA special or will this eventually be a production vehicle? I really hope that this makes it to market.
