We were originally talking about V6 sports sedans... That would rule out the SRT8-type cars as well as the S4.

I'm talking about this category from the original post:

"5) N-A 4-door sedan w/ automatic transmission"

The 340hp S4 can be had with an auto tranny and it's naturally aspirated.

But it doesn't really have faster 0-60 than the IS350. I've seen 5.3-5.6 seconds, same range as the IS350.

Now if they made the RS4 with an auto, *that* would win this category hands down. 420 hp NA V8, 0-60 in 4.7-4.8.

OK, gotcha. I just figure if there is no clutch pedal, and no manual rowing of the stick is mandatory for gear change, then the thing is an automatic.

jrock65

Didn't know that the S4 was even tested by anyone.

Anyway, it makes sense that it's about the same times as the IS350. The S4 auto has 11% more power, but it also weighs 11% more, mainly due to the AWD and the heavier V8.

Yup, more engine = more power, but awd + heavier chassis = more weight, overall it cancels out and you would expect similar 0-60 times.

Here is one review that says 0-60 in 5.3 sec, but I'm not familiar with this source so I don't know if it's reputable:

These people say 5.4 seconds with the manual, 5.7 with the auto, for the Avant (wagon) model:

The automatic NSX's on a conservative day did a low to flat 14 seconds. On average they usually did much better than that. Manual 5-Speed NA1 NSX's were solid mid 13 second cars and lower on good days. Manual 6-Speed NA-2 cars were solid low to flat 13 second cars and on a good day have been printed in magazines to have done a 12.8 second 1/4 miles. Those are just the normal USDM versions. If we through in the JDM S-Zero, Type S, and of course the NSX Type R versions we are looking at near mid 12 seconds on a good day for the NSX-R and easy 12.8s.

You are right though. When the NSX producton ends at the end of the year which is now, the IS350 will probably be the NA V6 current production king for a little while My gues though is Infiniti with the updated G35 engine will match it, and the upcoming Infiniti GTR will probably take over as king for a long time after that.

jrock65

I don't think the GTR is going to be naturally aspirated.

Is it going to be twin turbo? That would be cool. Personally, I actually hope they do put a turbo in it

But, IS350 NA engine makes 306hp and Supra Turbo makes 320.
Back 1997 Toyota Supra stop production cars, Toyota bring up new baby IS350 fights other high performaces sport sedan segment? Not as good Toyota Supra handling and styling too!
