So the Q50 is about the same weight, same size, same engine, and same transmission. Yet the Q50 is faster and better on gas?? How??

I see the rear end gear ratio is different. I have seen two Q50 dynos 290-300 at wheels...thats about 350hp at the engine. From photos the engine appears to be the same. I guess the changes are in the VVEL tuning.

 

Dynos can say what they want it too. My wife has the Q50 and it doesn't feel any faster than my G37X Coupe, BTW actually feels not as quick? BTW my coupe is back to stock form also

 

a dyno varies.

its more or less the same power, actually slightly slower.

more technology and different style

2014 Infiniti Q50S First Test - Motor Trend

 

I think it comes with the IPL tune standard

 

The hybrid variant makes more power than the non-hybrid variant.

 

We have a Q50 as well, it does seem a bit quicker.. Maybe because the G is a 6MT and the 7AT seems to have shorter gearing. The engine is a lot smoother for sure though.

 

I drove my friends q50. It felt quick, not what I would call fast.
Then again some mods with bolt ons & a tune would wake it up a bit.
Steering is a little strange, very artificial feeling.

 

I am also not happy w/ the Q50. Maybe I am not ready for change but do live the new body but the interior I just don't like it

 

The Q50 is a much more tame ride. Quieter, smoother, more disconnected if you will. You get a few more inches of room in the back seat and some of the best styling and tech out there right now, but I personally prefer the drive of the g37.

 

We bought the 358th Q45 made, SO..............I was expecting a 5.0 L V8 making about um, 480HP! Pretty naive huh Q50 is a marketing ploy!

 

That Mustang dyno is running the "Dynojet" calibration like the Mustang dyno here at Cobb SoCal. In all reality I'll bet the Q50 wouldn't make more or less power than the G37.

For example, my old '12 STi made 319whp on Cobb's Mustang dyno, but only 311whp on a standard Dynojet. Dyno's are extremely easy to manipulate and really should only be used as tuning tools to show the performance improvement (or decline) of particular parts or tunes.

Not to mention the numerous other things that come into play with dyno numbers: fuel quality, tire pressure, strap tension, etc.

 

6mtg37s,

I had a 7AT before. It felt faster than my 6MT, but it really wasn't much different except right off the line. I have an on ramp that I can use to judge and the difference is insignificant.

 

different materials in the engine (lighter engine) and different tuning. Also the tranny mapping is different.

 

Dynos are not meant to be absolute. They only provide a "rough" difference in measured power between modifications.

 

The engine is lighter? From what I understand it's exactly the same engine. And it's basically all aluminum anyway.
