Expected to power the next-generation Genesis coupe, previewed above in the HND-9 concept, details of the 3.3-liter twin-turbo V6 have leaked onto the Internet.

Engine output will reportedly be rated at 365 hp with 379 lb-ft of torque. Compared to the current 3.8-liter naturally-aspirated 3.8-liter V6 engine, the twin-turbo mill provides 27 more horsepower and 84 lb-ft of torque. It is also expected to be a more fuel efficient engine.

Cool! I hope the put wider tires than the measly 245's on the back this time

Torque is...tolerable. HP isnt cutting it. Hyundai, you want my $40K+ let me tell you. Realistically, (finally a non drunk post by me-but seriously) you want me to buy the next Gen Coupe? Sexier body, 13+...not bad, you can do better. Lose the wavy line thing. Obviously independent suspension. Offer two to three models. Hard ass "Track" models, base (with options) and a GT. Few choices of leather interior. Grey stone, black (of course-but boring yet it sells), mocca, dark brown, with stitching (charge a bit more), and baseball glove. I want minimum 7.5 color display (like I have now almost), touch control with text messaging interface, email, pandora, etc. Obviously Bluetooth, hands free everything, voice control that works. Homelink, Bluelink, I use it everyday and will pay for it again. Sending directions to the NAV from my phone, start engine, horns light-keep it) Sunroof, 10 speakers minimum. Power seats with at least 6 controls. Back seats (if you have them-dont care, make sure they fold down). Love the option of my current 3.8 taking that piss water gas and not hurting it. Do that again, not that itll ever see it but its a confidence thing. Decent brakes, I dont need 6 piston Brembos but good stuff. Weight..cut it where you can. Its understood modern cars are heavy with all the safety crap. Try to keep the top end, loaded no more than 3600 lbs. Engine...drop the 5.0 in there. MINIMUM 420HP with 390TQ. I could care less about MPG. Or the 3.3L Turbo, or whatever. It HAS to hit those numbers or VERY close. Make it and I will buy one, pretty much optioned out with the 100K warranty for...$41K...ish. There it is. Make it happen.

Torque is tolerable? More like a huge improvement over the current generation. It produces peak torque of 380 lb. ft at just 1500 RPM. That's going to launch the car like a rocket that this car desperately needs if it's going to have the same curb weight with the current genesis coupe.

The current genesis 3.8 coupe can do 0-60 at 5-6 seconds, I believe the next gen coupe will do it around 4.5 sec. This car needs more torque.

There is a reason why Hyundai isn't giving the V6 a 420HP 390TQ and that reason is so that it doesn't compete with their 5.0L V8.

The cons about this car is that the turbo is REALLY small, so the tuning potential of increasing boost might be limited.

You're losing half a liter of displacement, so, yeah. Just look at BMWs, 3.0L twin turbos rated at 300hp. This ain't half bad. I rather have 380ft-lb of torque than 298 even if the power remained the same. This ought to make the car far, far quicker than the 3.8L. If they keep the weight in check, we're looking at mid 4s for 0-60s.
 
#11 ·
You're making it off as though 365 horsepower isn't a lot, when in reality, it is; and, it goes hand in hand with the amount of torque that the engine reportedly has.

I wouldn't put the 3.3TT off until the final product is out, but this has a lot of potential for what it is, specially if you're into tuning.
 
#17 ·
Im not impressed either. Though '13 just came out by 17 id like to see more improvement.
 
#19 ·
You can't have your cake and eat it too, unless you're willing to pay up. The only way you're going to realistically have the figures you want in a sports car is with a performance luxury sedan/coupe (60k+) or with a high-end american muscle car (40k+).

To your disadvantage, Hyundai is probably going to line this 3.3TT around 36k. If there does turn out to be a V8, you're probably looking at 45 grand to line it up with the E-Class, 435i and the Q-60.
 
#22 ·
I like NA cars, but I'm not one to complain about good turbo'd engines ;)
 
#24 ·
Nah... to the NA purist, a turbo is somehow "cheating" because a turbo breaks the rule of "there's no replacement for displacement".
 
#25 · (Edited)
No hate for turbos, they're awesome, but they don't break the no replacement for displacement rule since pressurizing a motor is kind of a different ballgame. Any size motor can be boosted and have fairly similar gains ratio wise. A truer "replacement for displacement" is running higher RPMs. If a smaller engine with less rotating mass can spin faster it makes up for some displacement loss. Nowadays they have NA 10 and 11 liter motors spinning over 8000rpm and making 100hp/liter, so that's kind of gone out the window. But huge ass motors mean huge ass cars and those aren't fun to drive outside of straight lines. So yeah, turbo. But not replacement for displacement.

My .02:

The 3.3TT makes sense, but they may be stuck below the competition this time around. Infiniti's new 3.0TT for the new Q60 is supposed to make 400 with a 450hp version coming at some point. Hyundai may be making room for the "N" coupe to run more boost so it can make in the 425-450 range, or they may go the way of the Lexus RC-F and drop the 5.0 liter in it. I'm not sure if Hyundai can tune their 5.0 NA to make 467+ HP reliably, and they wouldn't go head to head with the RC-F and the same size motor and not be able to at least match the hp numbers. So I'm thinking they are making room by rating the base at 365 and having the N car use the same 3.3TT with more boost at somewhere below M3/RC-F hp numbers but starting at around $50k.

This thread is hilarious to me. 380tq from the factory means that it is pretty much guaranteed to come with a strong clutch. Twin turbos from the factory is an awesome platform. Twin 13T's on my old 3000GT with 2998cc's were pushing 400whp and 380+wtq all day every day on an engine that made like 210bhp N/A. If they went with twin 19T's, you are looking at cresting 500whp quite easily on factory turbos with a tune and supporting mods. That has NEVER been possible in a Genesis coupe without either bolting on a turbo to the 3.8's and pushing the limits or going hardcore with the 2.0T's.

The Twin turbo BMW's come with 300bhp/300tq with a 3L engine and people are pushing 440whp and 400+tq on factory turbos with bolt ons and a tune. I'm sorry but I don't care what you say, I would take a solid twin turbo V6 over a V8 any day of the week.

Not to hijack your convo here, but don't be entirely surprised if the next coupe isn't offered with a manual transmission. It may go automatic as standard with a DCT trans optional.
 
#29 ·
I would be REALLY shocked if the next Genesis coupe gets a DCT, I don't see it happening for a while AT ALL. The Veloster DCT is dry and just wait till you start reading about people modifying them and the clutches not holding up to the added abuse, you'll see...

the biggest reason Hyundai is going with the 3.3TT is the motor/drivetrain is lighter overall,and being overall more balanced/lower center of gravity,making it the best option for the allwheel drive package.

a few month's back this was the overall discussion from corporate Hyundai,and the 3.8 litre was also going to be retired from the 2017 model year,with the 3.3TT as the V6 only option.
 
#31 ·
400 rwhp / 420 rwtq is a real possibility with just a tune on this 3.3TT. Go full catless exhaust, BOV, intake, tune, and add another 20 to that probably.

Upgraded turbos, think stage 3 kit, and you are easily in the low to mid 500 rwhp range.

Remember, this is an engine built to handle boost from the factory.
 
#32 ·
THANK YOU!!! Exactly!! 420HP/390+TQ stock I dont think is a fairly tale at all!!

I know that there is a school of thought out there that says that you can throw a turbo on any engine. While this may be true, you really can't get the real benefit of using a turbo on a NA engine that was not built to be pressurized. You may be able to force in about 6-8 PSI before you start blowing rings and doing real damage to the engine. In the meantime, engines that are built to be pressurized are producing more power and more torque than engines with twice or even up to four times larger displacement simply by shoving more air and fuel into the cylinder.

An engine that was built to be pressurized can handle much more boost. For instance, right now I am pushing 27 PSI (peak) on my 2.0T. If you tried to boost a 3.8 to 20 PSI without a significant build, you'd be picking up the pieces parts of your exploded engine for days. There is a significant difference in the power you can produce with 6-8 lbs of boost versus 20+ lbs of boost. So... yeah.. the theory that you can get an equal amount of gain from adding a turbo to a NA engine is only true if you want to take apart the NA engine and rebuild its internals... so you get two Pinocchios for your statement.

If Hyundai moves forward with the 3.3TT, we may be looking at the next 2JZ motor if they do it right. Hopefully Hyundai has been paying attention to what Ford has done with the Mustang and Ecoboost and will follow suit. For those who have not been following, Mustang owners can pay Ford Racing for a tune that significantly increases power and will not affect the warranty. While this probably won't put our ECU tuner community out of business, it would certainly bring far more enthusiasts over to our platform.

Ford Racing really wants you to mod EcoBoost engines

Agree with everything here. The 3.3 has some serious potential and that tuned ecoboost is bad ass. Dont want one, but still bad ass.
 
#35 ·
I want to wait and see. The numbers they gave are preliminary and are not connected to any particular vehicle. Once it's in the GC we'll see what the power out is. I'm sure they will consider what the competition is putting out.

I'm more excited to see what the new Gen will look like because I know it will have a competent engine, considering their engine options. Heck, I'm happy with my 3.8 but wouldn't mind another 50HP/TQ
 
#42 ·
Higher compression in a Turbo motor is not desirable. You are shoving a ton of extra air into the cylinder so you don't need high compression ratios to compensate. High compression ratios btw is what makes an NA engine not suitable for high boost.
 
#44 ·
Well I wonder how it will be to service the 3.3T and its reliability.Hyundai had better do it right..Love the looks of the car just hope they offer a N/A engine ,V-6 not a V-8, and upgrade everything on the car and fix the dam blind spots and lack of vision backing up and far better backup lights!We shall soon see how much they want for it and what models and options are.........
 
#45 ·
Says not to derail thread. Talks about 2JZ :rofl::rofl::rofl:
 
#46 ·
My god you're helpless... If you don't understand what is being discussed and can't offer any intelligent or insightful information please circlejerk yourself somewhere else.

P.S. Yeah mentioning the 2JZ in a thread discussing a twin turbo motor with 6 cylinders is way out of left field... :x

I'm done. Let the discussion continue... :grin:
 
#47 ·
I actually like the appeal of a smaller displacement engine with more HP and Torque. Whatever the case, I'm not gonna judge the new iteration of the Genesis until it actually comes out. Until then it is all rather speculative.

One thing is certain, if Hyundai continues on the same trajectory I don't think we have anything to worry about. The 13+ were much better cars (not just engine, but other parts as well as interior quality) than the first generation, and if the new version has the same marked improvement then I'll be more than happy. Well, technically I'll only be happy once I upgrade to it....until then I'll just pine for it. :grin:
 
#53 ·
Well yeah, if you're talking price to performance then there's all kinds of different discussions around that. I was simply talking about the whole "replacement for displacement" issue in theory, and how FI is not truly replacing displacement. If you have a fixed engine size because you are needing to fit something into a smaller chassis, weight distribution, etc, then sure, boosting a motor is a great way to make extra power. But it's not replacing displacement. It's just a great way to make more power for motors of any size.

Car companies could totally design and produce bigger, boosted motors making in excess of 500hp and stick them in current cars and charge marginally more for them if they wanted to. Hyundai (or any major manufacturer) could have easily designed a factory boosted 3.0, 3.3, 3.8 instead of the 2.0 to begin with. Heck, I wouldn't be surprised if the 2.0T motor actually costed as much or more than the 3.8 NA (non-GDI) did to produce. Hence the 3.3TT they have now. But, you can't sell 500hp cars for 30k, because then you have all sorts of problems -- fuel consumption wise, safety wise, and it screws up the whole economy and market of your bigger profit margin higher end car lines where customers will then demand 1000hp engines.

So, back on topic, I'm excited for the new 3.3TT. I'll probably end up buying one in 2017. But the issue I have is that I want to get one in 2017, and then of course I'll want to push more boost on it, but, I need that warranty, at least for the first 40k or so miles :/. 1st world problems. If they raise the price point too much though I'm definitely out. As much as the car has impressed me I'm just not going to pay the same for a GC as say a Q60, unless it's just way better looking.

I don't think we will ever see another 2JZ again. It just doesn't make sense from a manufacturer standpoint because there is no money to be made for them. Same reason why cars these days have limited potential and will for a while. I'm sure there's a set of rules between manufacturers in regards to how much power a car can have before it starts costing this much or being hindered by weight.
 
#52 ·
Yea but the amount of power some engines are putting is insane. But efficient. Nissan and Ford have a 1.0 liter putting out 130HP or more. At cost. A one liter!! Picture a Soda bottle!! LOL!!
