2015 Hyundai Genesis V8 vs V6

[StangKiller]

Read all of the reviews and I have been hearing the same thing. V8 is to heavy on the 2015s - some reviewers mentioned the air suspension was enticing but most agreed the V6 was the way to go.

I think it's basically the same as the first generation. Not exactly a whopping amount of added performance considering the amount of added power...

 

[Cut-Throat]

Are the alloy wheels the same design on the V6 as they are on the V8 ?

I had a 2012 RSpec. Great car but hard on transmissions. Went through two under warranty. Incidentally, was treated very well by Hyundai.
Test drove a 2013 V6, and bought it.
The V6 is a better balanced car. Back to back comparisons you really notice the front end weight differential. I think Hyundai underdesigned the eight speed transmission. Hence my problems, and I am comparatively easy on transmissions. Hyuundai protects the transmission with aggressive torque management (reduction) in lower gears. If this protection is imposed on the V6 it is not nearly as aggressive. Further, the V6 has a deeper rear end ratio. The end result is that VF6's standing start acceleration feels (to me) very close to that of the RSpec. At highway speed, the RSpec is much stronger.

It certainly appears that way...

So basically Hyundai has this great 420 horsepower V8 but it's nannied beyond all belief to save the transmission...

These I don't care for much.

These I Like.

From what I've read, not as much as with gen-1. The burnout videos indicate you can turn the Nannie systems off, I believe.

I am with you Cut-Throat, I prefer the second set of wheels too. I also really like the blue.

The base trim wheels on the 2015 Genesis look very similar to the 2014 Toyota Corolla alloy wheels (which I mentioned when I saw the spy photos at least 6 months ago). This just shows that Hyundai can spend hundreds of millions to engineer a new car, but they still are Hyundai, and basically have no taste:

I am not sure what trim level is required to get the Genesis wheels shown in the other pic, which are not great, but acceptable.

My guess is that the first set of wheels are on the V6 (18 inch Wheels) and the ones in the second picture I posted are on the V8 (19 inch Wheels).

You guys are funny to say the least. We here how I strapped on a new exhaust system and now my Genesis is amazing with all this power which may give an extra 20hp if you are lucky yet a V8 with only 100hp more than a V6 is barely noticeable? This is what car and driver had to say about the diferences.

The all-wheel-drive V-6 model, new to the lineup and a necessary for luxury buyers in certain regions, was also excellent, though the 311-horse 3.8-liter V-6 under the hood with the 3.8-liter felt underpowered after driving the bigger V-8.

When I'm mentioning "nannies" that keep things "safe" for the drive train in lower gears, I'm not meaning traction control or anything like that. I'm meaning limited torque is programmed into the ECU.

The extra 400lbs with the V8 is the problem.

The extra 400lbs with the V8 is the problem.

So you are saying if I bring 2 of my 200 lbs friends into a V6, I now have the equivalent of 211hp left from 311hp? Not trying to be a smart a$$ just that it does not add up.

400 lbs sounds like a heck of a lot and I seriously doubt the addition of 2 cylinders would weigh this much.

Adding AWD to either model will add 135 lbs which is not bad at all.

You do know the new Genesis V6 weighs about the same as the old V8 right?

 

[Sal Collaziano]

It's only hearsay. I read somewhere (I forget where) that the V8 Genesis is 400lbs heavier than the V6 Genesis. I also read that "off the line" both the V6 and V8 feel the same - telling me there's something going on to weaken the V8 - most likely to prevent issues with the drivetrain.

The big effect is the amount of weight over the front wheels. The V6 has much more ideal even weight distribution between front and rear. This affects handling, although it is probably not a big concern for many on this forum, who seem to favor a straight ahead muscle car, rather than a sport sedan with good handling.

I am not sure what the difference in weight difference is between the V6 and V8 for 2015. For 2009-2014 it was about 200 lbs, but people are saying it is 400 lbs for 2015. You cannot necessary just extrapolate based on number of cylinders, because the engines are different designs, not just the same design with different number of cylinders. Also, once you add the extra engine weight, then additional weight is needed to for the suspension and engine mounting parts. Also, the 2015 V8 has some luxury options that are standard that may increase the weight, but some of these may also get added on to V6 Ultimate Edition.

For 2009-2014 the weight difference was 200 lbs. But all the auto reviewers made the same comment about them being about the same off the line for those models, just like they are now.

Back in 2012 when the GDI engines were introduced, virtually every reviewer recommended the V6. But many of them appreciate good handling, which is not always a concern of every R-Spec driver.

SO true. Having driven both the 3.8 and the 5.0 versions of the 2013, the difference between the 5.0 V8 and the 3.8 V6 is night and day. I even had a co-worker that has a 3.8 Genny drive my R-Spec, and his reaction was basically "Holy SH*$!". But more importantly to me is just how effortlessly the 5.0 propels you down the road. You really don't need to wind the motor up at all to be doing 90 in no time flat. And when you do step on the gas with anger, the party is most definitely on.

Since the engines on the 2015 model is almost identical to the earlier generation, I can only imagine that the difference in engine performance characteristics between the two is also comparable.

I put 10k+ miles over several months on a 2012 V6 base before buying the 5.0. Which now has more than 22k. I can tell from first hand experience the V8 pulls much better from off the line and all speeds. Not complaining about the V6. Amazing car. The V8 takes it several steps above.

The V8 also works better on on twisty roads for power delivery and overall faster speeds.

Just got back from FL where I had a 2013 V6 base rental for two weeks. Great car. Did not have Dungflops, so it was pretty quiet. Still, when getting back into the 5.0 at home airport, again realized Tau 5.0 is in different class. As it should be.

I have no problems with the "reported" "peaky" torque curves on either engine. I do not experience this at all for naturally aspirated engines. Cannot wait to drive 2015 and fell what engines are like. With less horsepower, we will see if they lost anything. Have not seen a graph yet that shows major torque improvements over a broad range of RPM.

Comes from Motor Trend. http://www.motortrend.com/roadtests/sedans/1404_2015_hyundai_genesis_sedan_first_drive/

You cannot hide over 100hp and 100 ft/lbs of torque. Heck that's a 25% increase. Maybe off the line they are close but get up there a little and bye bye.

The heavy slant by the reviews for the was indeed surprising. It seemed like many reviews wanted to justify the V6 model and focused on everything they could to sell over the V8. It could have been an economic issue as much as a performance or balance issue, as the V8 pricing does head into the zone where competitors have a closer gap. I think this cars wow factor is in direct proportion to the price.
