https://www.autoevolution.com/news/jaguar-f-type-svr-spied-testing-in-colorado-rumor-says-inline-6-or-v8-turbo-116522.html

Just saw this, and while it's all just wild rumor and speculation now, it's crazy to think of a Jag flagship running a TT i6. I mean, I guess if it's good enough for Porsche...

 

Interesting, but that article also mentions the TT V8 from the M5 being used, which seems more likely. Porsche uses a flat 6, not inline. And the biggest inline 6 from BMW is 3.0L, which wouldn't be a suitable replacement for the supercharged 5.0L V8, even in M4 tune. And I really don't see Jaguar replacing even the V6 in the lineup with that engine, if for no reason other than the sound. I'd say the engines are not a problem as is. If they want to fix something, they should pare off a few hundred pounds.

 

Agreed, the existing engines are not a problem, the problem is that the deal with Ford to build them is coming to an end so JLR need to find replacements. The smart money is on BMW or Merc twin-turbo V8s as a stop-gap while JLR develop a 3.0 straight six petrol turbo Ingenium and maybe a 4.0 V8 petrol Ingenium, with either turbo(s) or an SC.

 

No.............

 

This is a stupid article based solely on the writer assuming these are future production camo vehicles and not just current production still covered in camo. That stuff is a total nightmare to pull off after it's been sitting for a few months, and it's not carefully applied. We've got at least 20 2017 jeep cherokees running around here in full camo just because no one has taken the time to remove it.

Also an inline 6 turbo would sound like garbage.

 

This could be all bluster, but there are many reports that BMW will develop a version of its TT V8 for Jaguar. If there's a BMW partnership already in place, it's plausible.

BMW Will Reportedly Supply Jaguar With Twin-Turbocharged V8s


Sharing parts among competitors in the luxury space is now common. Mercedes lends its GLA platform to Infiniti for QX30. They also sell motors to Pagani.

 

BMW I6 engines are one of the better engines out there. My all time favorite is M30 3.5L.

 

Why wouldn't Jaguar stay with super chargers and renew a deal with Ford? Cafe standards easier with turbos? I don't like this approach at all. Part of my purchase of this Jag and last was supercharged V8.

 

JLR has invested $billions in the Ingenium engine plant, with more to come, so it wouldn't make financial sense to renew the deal with Ford for the now 10 year old AJ126 and AJ133 engines.
Also it seems the Ingenium engines are all designed to work with turbos and not with superchargers, and who knows how much it costs JLR to buy the current pair of superchargers from Eaton.
Adding it all up I think supercharged Jags are soon to become a thing of the past, whether we like it or not.

 

It was reported a couple years ago that Jags new engines would eventually include an inline six for the F Type. It now seems to be later rather than sooner. I don't believe there was the option of continuing with Ford, think I read in Automotive News.

 

What is the advantage of an inline 6 vs a V6?

 

inline 6 motors are typically more responsive and lighter at the cost of packaging ... they take up a lot more room.

 

Ah, isn't a V6 smoother running too?

 

With the cost of developing a new v8 for limited higher end models it makes the most sense that jaguar future R cars will use a BMW developed TTV8 for this range of cars. It wouldn't make sense for them to sign the deal and not use it.

 

They can be, you don't have balancer shafts to control the yaw of the motor like in V configurations.

 

Inline 6 motors are better balanced and allow for greater engine bore size at the same deck height. However they can sacrifice stroke at the same height and are substantially longer. Packaging is a challenge on a short nose car.

 

Something like this perhaps

 

I6 are also more reliable - you have one head, one head gasket, and a simple chain setup... A lot less things to go wrong.

Also less overheating issues - exhaust goes out on one side, so it is much easier to correctly pipe the exhaust and deal with the heat.

 

Ah - those lovely SUs. Kiss goodbye to Ethanol in your fuel/gas/petrol...

 

Also less vibration!

I don't think the move from blowers to snails is such a bad thing.

For one, it will allow easier incremental power increases whereas now the V8 seems to be somewhat tapped out.

Secondly, it will allow it to keep up with the acceleration of competition. The Mercedes AMG GTS has less peak HP than a F type R or SVR but has significantly better acceleration according to a multitude of magazine tests. That's due to the broadness of a twin turbo power band that simply can't be matched.

Consider that a Mclaren 570S has less peak HP than a SVR but blows the doors off of it in acceleration tests. There are other factors such as weight and gearing, but that alone wouldn't make a 10-12mph trap speed difference.


I ordered an AMG GTR so we shall see how it compares... Both have 575 HP.
