Hi, buying the facelifted F-type and ran into some questions.

1. Is there a difference in the exhaust/engine/induction/any noise between P450 and P575? Are all exhaust and engine parts the same between the two? If they are, logic would say that the noise level is the same as well but I'm not sure. They even weigh the same to the last pound. Has anyone tried/heard both?

2. How do you visually differentiate between RWD and AWD on the P450 model? On the old model the bonnet vents were lower and more apart in the AWD version but I'm not sure this is the case anymore. Some AWD cars don't even have the AWD badge in the back so it's really confusing.
Cheers!

 

1. They have the same parts, just detuned

2. Exterior and Interior have a little different parts (front bumper vents are different, as well as rear diffuser on the R. Interior has different stitch patterns on the doors, and obviously the R branding on everything)

Someone might be a little more specific but that's all I noticed between them when I test drove both, I ended up going for the P450 R-Dynamic in the end and I'll just tune it in the future..saved me about $20k

 

What you are saying then is that the exhaust/engine noise is the same in the P450 despite being detuned, right?

 

I can't speak to the other model, but the if you purchase the P450, absolutely positively remove fuse #15. The difference in exhaust notes is phenomenal.

 

I know about the fuse, that's not my concern. My concern is that P450 might be more silent than P575 in general.

 

The P450 and P575 will sound exactly the same, perhaps except (and only) at full throttle since that's where you will see the extra HP and so the P575 might be a touch louder in that limited circumstance. However, that would be the exception and not the rule. What *is* the rule, however, is 2022 and newer P450/P575s in the USA now do have the Gasoline Particulate Filters (GPF) embedded into each of the cats for emissions requirements (not required in the USA--even in CARB states like CA) but because they've been required in the UK since something like 2019, JLR started building only one global configuration starting with the 2022 model year. The GPFs significantly reduce the overall volume of both versions and you can't remove them (without gutting the cats) because they are completely integrated into the cats. A 2021 P450 will sound significantly louder than a 2022-2024 P450 or P575, including the pops and bangs. And everything sounds quieter still than the 2016s and earlier (with no software patch), as those cars were raucously (and fantastically) loud.

I just recently installed a VAP valvetronic exhaust on my 2023 P450 and that restores most of the fun, and I also have the remote relay for Fuse 15 so that restores the rest of the fun.

 

OK, thanks I will not lose sleep over this anymore.

 

Regarding the 2nd question, AWD vs RWD, if the owner chose to 'debadge' the car (which for UK MY21 cars only removes the P300/P450/P450AWD badge on the rear) then there is going to be zero external difference between a RWD and AWD P450. You'd have to get underneath and look for the telltale signs there, though somebody else will need to point you in the direction of exactly what to look for there.

 

For '22 and '23 the front fascia side vents are different on the RWD vs AWD.

 

You mean side vents in the front bumper? Sorry, I can't see any difference. I might be going blind though, can you post two pictures so we can see the difference?

 

Every day is a school day

 

I'd like to learn what those differences are as I can't trust dealers to tell me which car is AWD and which is RWD.
Hoping for Thunder Dump to reveal the secret.

 

Are the hood vents positioned in the same place in the new range for RWD and AWD? That used to be an easy differentiator, be a shame if they've stopped doing that.

 

Yes, looks like that...

EDIT: biggest problem is I have to pay JLR TOPIx subscription to get the correct specs each time a new car comes online.

 

This is AWD. Note the L-shaped plastic body-colored piece on the back/bottom side of the front vent:


This is RWD. Notice the L-shape piece is missing. This is unique to the '22-'23 R-Dynamic RWD models:

 

Maybe it's depending on the market but in Europe where I'm from there are plenty of RWD cars with the L-shaped piece in the side vents.

Here's couple of examples:

So for me the mistery continues. Worst thing is I have to pay 30 bucks for one hour of Jaguar Topix subscription just to find out whether the car is AWD or RWD as the used car dealers can't be trusted to know.

 

It might be worth examining the VIN as character 5 was used on some models to denote AWD or RWD, e.g. J in char 5 used to mean ;LHD AWD; and L was 'RHD AWD'.but I don't know if it changed on the later models.

 

The first example is a 450 First Edition, which was a 2021 model year and not an R-Dynamic, and the second example is a 450 75th which is a 2024. As noted in my post, the front vent differences for AWD vs RWD R-Dynamics only apply to the '22 and '23 model years.

 

That's interesting (and more confusing) - my My18 has 'A' at digit 5 (RHD AWD).

 

So you're saying that AWD can be differentiated from RWD only on R-Dynamic trim and only on 22-23 model years? Below are some of those models that challenge this theory. As you can see, they are all 22-23 model year R-Dynamic with an L-shaped piece in the vents. I'd love if you prove me wrong again, as it would make my life easier. But I checked the first one in Topix and it is confirmed RWD...
