What do you guys think of the engine change on the "upgraded" XE?

From the 6cylinder supercharged, to 4cyl turbo?

Is it OK to buy the old one...will it be supported for parts? Is that an old Ford engine?

 

I'd rather a supercharged 6 to the turbo 4 if they were the same price.

First the supercharged 6 is likely to have less lag (though they are a little laggy, or is that transmission?);

Second it is only an ECU mod to get it to the 280KW of the S;

Third they will still be using that engine in one form or another until the 6 cyl igenium comes out, it has been used a lot in the XF and the F Type so Jag wont be stopping support in a hurry;

Fourth, it is likely to sound better;

Fifth, the igenium is a new engine and may have a shakedown period.

Against the 6 is that it is likely to be a little thirstier, and more for registration costs if yours work on cylinders as ours do.

As for whether it is the old ford engine, it is essentially the AJ engine that wound up being the 5.0 and 5.0SC that came out in 2009, but with 2 cylinders blanked off on my understanding.

 

Beyond what has been stated already...

Jaguar is a supercharged engine marque; not turbo. It's a more fitting engine since supercharging has been Jag's forte for decades.

 

You should not worry about parts availability for the 6 cyl...in 2018 and probably 2019 and 2020 they will still continue to put that exact 6-cyl engine in the sport vairants of the F-Pace, XE, and in the v6 F-Type, so there is plenty of support still for that engine, and there will be tons of parts.

Having driven the 6 cyl for 13K Miles now, I strongly suggest you choose the supercharged 6 cyl over the turbo 4cyl. You'll get 44HP more right off the bat from the factory, NO turbo lag, and this engine pulls smooth and hard all the way through the rev range...I'm in love with this 6cyl.

I've driven plenty of turbos (but not the new Jag), and prefer the smother hard pull of the supercharger, hands down.

Here is an article on the 4 Cyl..... 296 HP and 295 Torque in the 2018, vs 340 HP and 335 Torque in the 2017. (But you can always buy the 6 cyl in 2018 in the re-badged and trimmed "S" variant, for about $9K more that is...Personally I'm not sure the letter "s' and the side skirts are worth the difference in pricing in my book...)

There is no noticeable turbo lag by what I could tell, this is 2017 gone are the days now of waiting for the turbo to spool up for boost. It has max torque from 1200rpm - 4500rpm which means it’ll pull in any gear. It’s lighter, costs less and is a great drive. The V6 sounds nicer though.

Fastest car Jag ever made was turbocharged (XJ220), good enough for me!

 

The supercharger "lag" is definitely from the transmission. Really wish jaguar spent more time mastering the best transmission hardware available for a midteir car.

 

Yes, I have the V6 S in my f type and I think it is transmission that is laggy. In fact some times it revs freely for a half a second before "engaging" when changing gears which is possibly an ECU thing designed to allow blipping etc. But a few of the manual drivers on the f type forum have said even in the manual it is a touch laggy.

But compared to the 6 speed in my XKR, the 8 speed is lightning fast, and I'd have it over a DCT any day of the week.

 

Maserati has nailed it on the Ghibli and Qporte

 

From Jaguar's own website "Project 8 is the fastest Jaguar saloon ever. "

It's a supercharged v8, not turbo.

Yes, the T4 is considerably less cost to produce for Jaguar. Makes me wonder what the savings comes from?

But the AJ133 has been the tried and tested platform for years, this is one of the many reasons they built thier supercar off this engine.

The AJ133 also has much more 'Headroom" for those of us that will tune up our cars, you can get an additional 77 hp out of it with a simple ecu tune, putting total output at around 416Hp..for $900.00.

A good tuner and a few more upgrades later (exhaust, pulleys), and you're near 500Hp with the 6 cyl. In the hands of the SVR team, the v8 version in the Project 8 is making near/or over 800HP at the shaft!

 

The XJ220 isn’t a saloon, it’s a genuine 2 door supercar that won Le Man in 1993 it also did 213mph or 217mph without catalyst converters by Martin Brundle and was the world’s fastest car powered by a twin turbo V6 engine.

Project 8 can do 200mph and is a 4 door saloon.

The AJ200 turbo engine is at 296bhp in the top spec guise with a ceramic roller bearing turbo and 9.5:1 compression. The 200/250 version aren’t using ceramic bearings and have a 10.5:1 compression. I wonder what could be got out the AJ200 with tuning.

 

I stand corrected. Although I doubt the AJ220 can pass today's emissions whereas the Project 8 just snuffs by USA regs. I do like ceramic bearings, I remember reading the AJ engine also has some special bearing considerations for extending longevity, but not ceramic.

And as we are talking here specifically in the XE section, I was assuming we are talking saloons. My bad.

 

I mentioned the XJ220 as a previous post stated that Jaguar's history is supercharged not turbo, where as there is history of both.

The AJ200 4 cylinder turbo engine in the XE, XF, F-Pace and F-Type is too new to know what it's limits are at the moment, at least we know 296bhp is what Jaguar currently have it running at safely. AWD 30t does 60 in 5.2, same as the 340bhp 35t/S did. Which was the reason for the 40bhp bump on the S model.

 

Funnily enough (and getting off track) the XJ220 was supposed to be a V12. It was also supposed to have scissor doors and AWD. Various constraints meant it had to be a turbo 6, RWD, and normal doors and with a market crash buyers tried to escape their commitments but failed. Ultimately though it was a truly awesome car, the fasted production car made until the F1 came along.

 

According to these fellas the 0-60 on the 2017 6 cyl is 4.5 Sec.

(Not to mention it takes around 4 seconds with a tune).

And here car and driver states the prices of all the 2018 XE went UP, not down.

So the 2018 gives you LESS engine for MORE money. Unless the experts got it wrong. Sounds like an easy decision to me.

2018 Jaguar XE Updated with New Engine Options ? News ? Car and Driver

"Compared with the 2017 model, the 2018 Jaguar XE 25t’s base price is $825 higher, at $36,720, with prices rising commensurately for the Premium, Prestige, and R-Sport trim levels"

 

Thank you all for the response.

I have a 2L turbo car now. Turbolag can be annoying, but on my car putting it onto Sport Mode eliminates that. It's definitely programming that causes it, not hardware.

I was asking about the v6 Supercharged engine being phased out, because right now JaguarUSA lists 2L i4 turbo engines for all 3 variants of the 2018 XE. Doesn't list a Supercharged V6.

I avoided getting the 2017 XE 2L turbo since that ecoboost engine was being eliminated across both lines. I just don't want to be in a situation 5 years from now where I need a timing chain tensioner or something, and I can't get it.

 

I think its safe to say the AJ30 engine will have plenty of parts available.

And just a sleight correction...the AJ30 is not pulled from the XE line, it is only available in the "S" version now. So you can still buy one in 2018.

And in 2018 they are still using the v6 engine in two of the XJ and XF models, as well as in every F-Pace "S" SUV, which is selling great in their fastest growing market segment.....

So this engine if far from discontinued. In 2018 it is still the engine of choice for their best performing versions on the XE and F-Pace.

 

Jaguar is on the up and up. Selling a lot of cars (for them) globally. I would not worry on any parts for any car for long long time.

 

im weary about the 4cyl engine. i havent driven it, but ive driven other 4cyl cars. my wife had a 328 that i tuned to get 290'ish hp.....and even though it had that extra few hp, it still just didnt have that umphf that you get with a v6, and DEFINITELY not with the sound

 

Thanks everyone.
