Took a ride in the Genesis (5.0)

[anonymous1]

The genesis 5.0 ride tonight was impressive was extremely quiet for a V8 and I timed 0-60 @ 4.84 average on IPhone timer, my question is how the hell did Hyundai get the V8 RWD just as fast as the previous r spec model considering its weight increase (but I do know weight of the new model plays a role in the extra grip)?

Someone else in this forum said they raced a 2015 V8 against the R-Spec multiple times, and the R-Spec consistently won by 1-2 car lengths at 0-60 MPH, so my guess is that your iPhone timer is not accurate.

Or maybe the driver of the R-Spec had better reaction times

You are probably right though. iPhone timer doesn't sound very scientific.

Given that they both had the Tau 5.0 V8 (although 2015 had slightly less HP rating), both have Hyundai 8-speed tranny (possibly different shift points), and 2015 is quite a bit heavier, and that there were multiple 0-60 runs, I suspect that the 1-2 car-length difference is accurate (R-Spec was faster).

DeNile is not a river in Africa.

While I think that 0-60 time is probably optimistic, without knowing which timer app, it's not really possible to blame the application. The Cocoa NSTimeInterval api will measure to sub millisecond precision, while the mach apis are much more accurate. On Android using the NDK I can very easily get very precise timings. I think the big weakness is hand-timing things is the human, not the timing apparatus.

In any case, I wouldn't expect sub-5.0 second 0-60 times, but I'd be happy with the low 5.0s.

Not denying anything. If you noticed I actually said "you are probably right".

5.0 0-60 is plenty good enough for me!

1. Just joking. But seems there are some people (especially in other threads) who have tried to talk themselves into the idea that the 2015 V8 is as fast (or faster) than the R-Spec sedan.
2. The 3.8 is good enough for me, so I actually have no idea why anyone cares about this subject.

The thing is that both are likely to be right. The '15 is almost certainly a bit slower if tested properly, but at the same time the difference is almost certain to be small enough to be made up in launch style in an informal street race if that's your criterion.

Who cares when they seem to be close enough that a big guy/vs small guy behind the seat and a full tank/empty tank and as mentioned driving technique will make the difference between a winner. If anything it is fairly negligible unless you are track racing and milliseconds are precious. All I know is I get a big grin on my face every time I drive my 5.0 and that is all that matters. Do I wish I had more power? No. More than enough for me and as I have mentioned before, effortless power. The Tau V8 has been described by many reviewers at "buttery smooth" which it is. The engine has been refined over the few years it has been out and nothing but improvements as a result. They lowered the HP figures slightly and upped the torque for a valid reason which many here do not understand as all they see is the mighty HP but that is really only a very small part of the overall power of the engine. How about the Mercedes E250 Blu Tech diesel which will perform as well in 0-60 as the V6 Genesis but has only 195hp in a package that weighs more? The freakin torque is almost 400ft/lbs, that's why, screw the HP!

Area under the curve.

I do wish manufacturers made torque and HP curves readily available. Peak values only tell part of the story.

I completely agree, it wouldn't be surprising at all to me to find out the average available power throughout a 0-60 run actually increased even if peak power is off by 9.

Agreed. Torque vs. RPM curve shape is a big deal on how a car feels while driving.
