!Is hyundai starting to underate their engines?

[anonymous1]

For the 2015 genesis both engines feel so effortless and smooth for 2015, i know torque jumped on both engines but im not convinced that they lost as much horsepower from the previous generation as they state. I think the horsepower "claims"may be more conservative for 2015 concidering how hyundai tweeked manifolds, induction systems, higher compression ratios, upgraded injection mapping, and lastly lower friction belts and coatings. I guess we wont know until we see dyno results later. 2015 owners feel free to chime in on this.

Since this is my first sedan, I can't speak from experience. However, after reading what many previous gen owners have written about the noticeable tq difference in the current gen, you may be on to something. Except it's the tq that has been underrated.

Since the torque was increased as well as the transmission mapping, that is what many may "feel" when determining power. Not sure why Hyundai would publicly underrate the actual HP rating - I think this is the result of the increased torque which can be felt even in small increases.

The power band is much different than the Gen 1. It is more linear.

To fit in with the rest of the luxury market.

This whole topic was discussed at length before the car came out, and I was one of the people also anticipating that they may have started rating their cars more conservatively. The example given at the time was the Infiniti M56, which was listed at 420 and on the same dyno made 10 more hp than the Gen 1 Genesis that was advertised as 429.

There's certainly a marketing benefit to advertising as much HP as you can legally/ethically do, but it's balanced pretty strongly by reviewers and gearheads noticing that even accounting for weight that apples aren't being compared to apples -- that the car that doesn't have any "cushion" in its rating continuously disappoints compared to its perceived competitors.

It's possible hyundai got tired of the horsepower vs hyundaipower joke.

There is no doubt my 2015 3.8 is slower than my 2012 3.8. The 2015 is heavier so it makes direct power comparisons difficult. If we're talking just speed I took it on the exact same stretch that I ran every day with my 2012 when I was still driving the 2012, and the 2015 was noticeably down on power.

Not to a huge degree though. Overall I like the power band of the 2015 so much better it's not even funny. Love the vastly improved exhaust note and I don't even know what kind of magic they worked with the tranny, feels like a whole different unit (it's not.)

So yeah, a little slower but not too much, and the other qualities make me prefer the 2015. The midrange torque is quite a bit better.

edit: and to answer your question about Hyundai starting to underrate their engines, only one way to find out: dyno it!

I know they tuned the 5.0 for more low-end torque vs. top end horsepower, which is probably what they should have done in rev1 starting in 2012. I would much prefer this to high-end power I would seldom use above 4K RPMs.
