I know this has been discussed to death but again bringing up. How did motor trend igniton get 0-60 time on the v8s to 3.4 sec while the R awd drive was at 3.6. on head to head. That makes no sense to me what so ever. Maybe a chime in would be great.

 

Different conditions/different traction (the awd should have a huge advantage on take off, but the conditions might be different), the awd is 80 kg (175 pound) heavier etc.


The claimed 0-60/62 times for the rwd R vs awd R is in favour of the awd (0.2 sec), but the 50-75 times is in favour of the rwd (0.2 sec) - probably because of the added weight of the awd.

 

Added drive train losses for the AWD also which should be negated by the additional power.

 

Completely understand what your saying but still that's a pretty big gap. So what are the avg 0-60 on v8s vs r. From my calculations there pretty dead even even though there is 55hp difference supposedly

 

There's been a few dynos run on the V8S that suggest the 488hp variant really performs more closely to 510hp. Compared to the 542hp of the R, that's not a whole hell of a lot. Obviously dyno readings car vary based on conditions, but so can 0-60 times just the same. For what it's worth, I pulled a 3.3 second 0-60 in my AWD R on the strip.

 

What they said; mostly variations due to the usual conditions......however, there is no 55hp difference between the V8S and V8R and, as mentioned, there is a +170/200 lbs for the AWD variants as well.

I believe the real HP difference is likely 35 - 40hp and the weight penalty is worth 20-25hp so it's not surprising that the times are very close.

That said, if you tested 50 cars back to back with all the same conditions, I think you'd find the AWD R to be ahead in a 0-60 run the vast majority of the time.

agree that awd should be the quickest but the 15s had launch control while correct me if I am wrong the awd ones do not. That would make a difference in my opinion as the computer would def calculate road surface temp etc better then its human counter part. But that is obviously subjective

 

V6S is the only model that has ever had launch control ('dynamic launch').

 

Really...that doesn't seem right. i feel all 14s and 15s had dynamic launch, but could be completely wrong

 

To clarify: V6S with automatic transmission.

 

The AWD hooks up so much better, it's almost automatic. BUT... I think that with weight and drivetrain loss of the AWD, the RWD *could* win. It takes some serious skill though..

Anyone that can get a RWD to beat a AWD is a pretty darn good driver. IMHO, that's the explanation; A skilled launch artist.

I'd bet a RWD win rarely happens with us mortals.

 

This is something i agree with a 100%

 

My V8S does not have launch control even though the Owner's Manual states that it does.

 

I beg to differ. You forget the loose nut behind the wheel of the MT.

 

Yeah, its been well documented that the owners manual is wrong on this point. No launch control for any V8 model.

 

On all three Jags I have had the Owner's Manual is generic and not at all sub-model specific. So it lists pretty much everything the car could possibly have, even if it doesn't have lots of those things.

 

Does the base V6 have it or just the V6 S?

 

Can't a tune program a launch control? On the GT-R you could tune launch control to do what you wanted with aecuteck

 

We don't currently have that level of support; and we might night even have that capability. The stock ECU is pretty well locked down. We've only got a few companies working on F-type performance products compared to everyone and their mother who works on the GT-R. Completely different enthusiast base.

 

i understand the GT-R is obviously a lot more popular platform for modding enthusiast, but I wouldn't think the ECU of the Jag would be more difficult to crack then the gtr. I wonder if a tuner could chime in and tell us the complications of adding a launch procedure to a car.
