- The Genesis Coupe 3.8 R-Spec is an enthusiasts car. Because of this, our focus in this video is on the driving aspects. We also look into whether there's truth to rumors of inflated "Hyundai horsepower numbers". This video is to serve as a supplement to our full article review which discusses several other key aspects of the car which can be read at goaheadtakethew... . Please share and like this video - it really helps us! Thank you.
305whp for a 348hp is actually good since a
2010 camaro with a l99 auto makes 400hp and about 323whp
love the 2013's they really made it an incredible car, i'd take it over any of the v6 competitors on the market without even blinking. great job KDM
350hp x .20 = 280whp
350hp x .15 = 297.5whp
The numbers Hyundai claims seem about right.
+Greg Coleman yeah my 20 year old car has the same drivetrain loss as well, lol.
mine put down 292whp when stock
RE: Dyno Numbers being off from advertised numbers
After owning and driving my 2013 R-Spec 3.8 cold to hot for the first few weeks, I suspected a de-tune in the ECU until the engine is warmed up. Contacted the dealer service department and 2 of their techs confirmed the car will hold back until fully warmed up. Makes sense, since you shouldn't be pushing a high perf motor until it's all warmed up anyway.
So seems you need to run it at the proper operating temp (IE: fully warmed up) to get accurate dyno numbers. Don't let it get cold between runs. ;)
Explains me me getting on the freeway and going nowhere when trying to merge
you guys do realize SAE standards for power measurement are at the crank with the engine fully dressed.
Mine put out 280 whp fully stock on dynojet
I hop everyone gets that manufactures advertise crank horsepower which you can only accurately measure by taking the engine out of the car and putting on an engine dyno, and wheel horsepower tends to be so,we here around a 15-20% loss in RWD car and maybe the same if not a little more like 25-30% in AWD cars because of parasitic losses like the transmission differential and such. So when you do that math Hyundai's numbers are within a few horsepower of the actual horsepower on this dyno, which every car makes a little bit different power so it makes perfect sense
Justin Walters really bugs me when people do this. That actually shows about exactly what they claim at the motor if not slightly more. How hard is it to differentiate wheel hp from flywheel hp?
Isnt fwd 15% rwd 25% and awd 30%. The tl sh 2010 has about 305-315hp but only gets about 225 whp
Preval_xMiist 30% is terrible loss even for awd, awd at most should be 20%, rwd around 15% and about the same for fwd
You say the hp numbers are inflated? You do understand there's a average 15-20% difference in crank vs wheel hp right? And that car companies rate their engines by crank hp.
I own this exact model, in black. I first drove the 2013 Nissan 370Z Nismo, which is a great car, but opted instead for the 2013 Genesis 3.8 because it costed considerably less than the Nissan, has more interior cabin space, a better look (in my humble opinion), and I felt the power to be slightly better than the Nissan's. Glad to see these dyno numbers; thanks...
Same. my story was exactly the same as yours. cars still running w out a hitch. 66k mi. should i switch the tranny oil now you think? still warrantied but cold air intake will happen
I own a 2015 nismo 370z, and am planing on getting a 2015 genesis, only because now I have a baby... Hate the way the interior looks during the day though ><
And I've seen a 2014 genesis ultimate, on a regular dyno, the numbers were around 280hp ish....
Great review!
I'm confused, and maybe it's just me but, why were you impressed with the BHP numbers when they fell well below the stated amount? Thanks!
That luigi90210 guy sure was defending the hell out of his Nissan 370. Poor mans GT-R? I report, you decide.
This genesis has as much horsepower as the 96 mustang cobra was rated for. That's impressive coming from a v6. Of corse it has less torque than a v8 which is expected.
Less friction and heat losses possibly
oh and if you think the genesis coupe has lighter weight wheels then the nismo 370z does, you clearly dont know how much forged aluminum wheels weigh
this is true but i feel those numbers are inflated and they wernt accurate
i have seen dynos for the genesis coupe and numbers are more realistic(280-290whp and 250wtq) and while you are right, dynos are not a good way of measuring exact horsepower, people take them as fact all the time and use them to shove their hp in others faces when their car isnt really making that much power
you feel that way cause you KNOW you spend 17k more on that Nizmo that ISNT any faster ROFL. No really, it ISN'T ANY FASTER.
not how it works at all, but ok
running lighter wheels will give you more WHP, running stretched tires will give you more WHP
this car's dyno is over inflated(like all dynapack dynos) because its missing its wheels
my Nismo 370z will dyno in at 315 on a dynapack but will only dyno @ 300whp on a dynojet
a genesis coupe 3.8 Rspec will dyno in anywhere from 280-290whp on a dynojet
yusss
Uh self explanatory if you make the same flywheel power but have less at the wheels you have more drivetrain loss through heat and friction, not rocket science
about the same?
the gen coupe weighs more than a G coupe, im much lighter than a G coupe
3200lbs and only getting lighter
damn this was 6 years ago ? i hope now you realize the G37 is heavy af at 3600-3700 pounds while the Genesis it at 3400-3500
what?
.... wow dude, sorry you don't understand basic car terminology, less power at the wheels... through the aforementioned heat and friction problem, i'm just saying its possible. Not really worried about weight since both cars are about the same...
are you mad you spent a few extra grand for a 2 seater? you could have gotten a miata instead :)
later
does it come with LSD?
The r spec and gt versions do, not sure about the other ones
FYI All Canadian 3.8's 2013+ have LSD.
why because im calling out the truth
dynapack dynos read higher because they REMOVE THE WHEELS
i run 300whp stock on a DYNOJET(you know ones that keeps the wheels on the car)
if you think a stock gencoupe will out dyno a stock 370z Nismo, you have lost it...
I owned a fast car. A 96 tsi fully built. Now it's time to obey posted speed limits and get a very nice car so I got a 14 rspec. I doubt whatever you had was faster than a car I'm saying I had that was quick. I still dont get your point so yeah.
Damn almost a 50 hp loss? Either way 300+ stock is good
The stated number of 348 would be at the crank, 50 hp loss thru parasitic transmission/rear-end isn't that bad. I love the genesis, I'm just curious how tight the tolerances are in the motor, and if after 100k miles they just spontaneously combust!
It will loses even more with the wheels on
You won't lose much at all. The added mass of the wheels is miniscule compared to the reciprocating mass of the engine and drivetrain. Plus the RPM reduction from engine to wheels lessens the impact even more. This is all calibrated and compensated for by the measuring device anyway, so it's an accurate measurement.
this video was longer than it needed to be. you didnt need to show 3 versions of the same dyno run.
i call bullshit on those numbers, my 370z nismo makes 350 flywheel and my car only dynos at 290-300whp
a gen coupe makes 2hp less yet it dynos at 305whp?
bullshit
You sound mad
@@spectrum870 He sounds right. Unless the Gencoup has less drivetrain losses.
This car might dyno more here but I seen dyno in person not that high therr decently fast but no 370z
every car on the market losses 15-20% Even your piss ant 370z
@@rabidrizon977 the 370z is slightly faster than my first gen 3.8 so the 2nd gen 3.8 is just the same as the 370z
