When we first heard that Hyundai’s RWD Genesis Coupe would be offered with the choice of a naturally-aspirated V6 or a force-fed four-cylinder, it was easy to tell which would receive the lion’s share of attention from tuners.
But before the aftermarket gets busy bumping up the numbers, it’s imperative we know what the 2.0 litre turbo mill can do straight out of the box.
The lads at Inside Line have strapped a Genesis Coupe to the dyno and shared their results. The numbers indicate that there are good things ahead for the turbo Genesis, and numbers don’t lie.
That’s 147kW (197hp) at around the 6000rpm mark and peak torque of 311Nm (227 lb-ft) at 2500rpm.
Given the car is rated at 156kW and 305Nm (223ft-lb) at the flywheel it’s highly likely that the Genesis Coupe, like many turbo cars, is underrated from the factory.
The run-in question was performed in fourth gear, with third producing lower peak torque figures as the engine speed increased faster than the turbo could respond.
Inside Line also noted the above which shows how inefficient the factory exhaust system is.
On a turbo car, a free-flowing exhaust is imperative and can free up copious amounts of power and torque. It’s not hard to see where tuners will be looking for more power first.
We think there are big things ahead for Hyundai’s up-and-coming cult car and we’ll be absolutely devastated if it doesn’t wind up in Australia.
It’d be just our luck, of course, but we’d be devastated nonetheless. Still, fingers crossed.

“how inefficient the factory exhaust system is.”
NO.

fuel economy
EPA city/hwy econ : 21 / 30 mpg (!)
Who cares? They’re obviously talking about power.
Go buy a Prius.
Just because an exhaust is inefficient doesn’t mean the whole engine is. The restriction could be there to potentially increase engine economy by providing back-pressure. This would possibly keep some exhaust gas inside the cylinder, meaning that for some points in the usable RPM range the engine could run very lean - then again maybe there’s another reason….
This is what is of more concern though:
The run-in question was performed in fourth gear, with third producing lower peak torque figures as the engine speed increased faster than the turbo could respond.
So, if it can’t keep up in 3rd, what hope for 1st and 2nd? Effectively the car won’t be as accelerative as it could be because the turbo isn’t up to it.
my day to day experience is that many, if not most, pedestrians dont seem to rely on any sense at all before stepping onto roadways. so i have no doubt that any growth in electric cars will increase the incidence of pedestrian/car collisions. for my part, i think that would be a process which improved the quality of the gene pool, but, realistically, something will have to be done, even if it is something as apparently absurd as speakers going “vroom, vroom”. the follow up, of course, will be bose and apple teaming up to introduce software in iPods which cancels the sound of car engines, to improve the listening experience.
The coupe’s are very nice and the aftermarket is slowly starting to show up in here in the states. If you want to learn more or talk about the coupe visit our club site!
