Is this due to environmental restrictions, or just some other reason where time marches on?

Get the word out to buy your V8s now!

I admit, the V8s are great for going in a straight line, but not as appropriate as a successor on the curvy roads for grand touring like one might in a classic automobile like the E-type.

I just remembered a lot of your aren't even driving a manual, so I silently chuckled a bit. <--- yes I am salty as hell right now.

 

There's a manual?

These will always be depreciating cars, but the RWD 2015R is my bet for holding its long term value the best. Loud, brash V8 for me any day. Yes, I'm yesterday's news and a dinosaur in a world of Ubering Millennials I know.

 

It really doesn't surprise me that supercharger are going away, most of the other makers ditched them in favour of turbos a while ago.
If the V8 is replaced with a twin turbo V8 then not disappointed, if the V8 leaves and isn't replaced with another then I will be sad.
I still dream about a large twin turbo modern V12 Jaguar engine.

Reminds me of the sentiments expressed in this Top Gear clip about Aston Martin V12 Vantage

 

Yep and the SVR.

 

A more accurate story here:

Concerns mount over future of Bridgend Ford jobs as JLR cancels engine contract earlier than expected

 

this story has been reported > 1yr ago and several times on this forum.

JLR canceled their contract with ford to produce the AJ motor. JLR has reportedly signed a contract with BMW to produce/license their turbo V8 for use in the top of range models.

 

The fact that the Germans favour turbo charging over proper supercharging does not make it superior; in fact it is very much inferior when applied to petrol engines, although suiting diesels quite well. God help Jaguar if as rumoured, they use a BMW turbo charged V8, given BMW's engine disaster record of recent years.

 

In all honesty and as many of the reviews have pointed out the V6 is probably the optimal engine for the F. The V8 is a blast, but so is a Saturn Rocket. The goal is an eminently drivable performance machine. So if the V8 goes away, I will miss it as an object of desire, but I really won't be put out. Now, installing a BMW turbo V8 is a horse of a different color. For a performance machine where the performance is expected throughout the performance range a turbocharger doesn't do the job. Volvo's solution of a supercharger and a turbocharger is a solution and a recognition of the problem. But more than that the dilution of the brand, the admission that you can't produce an adequate motor, that you have to resort to a bulk supplier, that the product is a mix and nor a pure bred is hard to take. Remember the old Bugatti motto Le Pure Sang des Automobiles.

 

I hope not those BMW V8 TT as found in current M5's sound absolutely rubbish, really so much of a car for me is the noise and the BMW V8 TT motors really sound poor.

 

My indy, that deals heavily with BMWs, told me that these V8 TT engines are problematic, as positioning of turbos leads to heat soak and all kinds of turbo-related problems. Reportedly, they see a lot of them in the shop.

 

The V6 may be fine in the F type, but is lame in a "fast" saloon / sedan such as the XF or XJ, and would be hopeless in a Grand Tourer such as any XK replacement. Turbochargers should be confined to diesels, which in turn should be confined to the scrapyard.

 

A little delusional today are we?

 

JLR could learn a lesson from Aston Martin by acquiring the Mercedes AMG 4.0 liter twin turbo currently being placed in the 2019 Vantage. The "hot vee" placement of the turbos is optimum for efficiency in my humble opinion.

 

Our current front end area may not be able to package the intercooler necessary to compensate for the heat soak of that design. However, yes it is far more efficient than traditional twins.

 

"We" are not, but if you believe that turbochargers are superior to mechanically driven superchargers when applied to petrol engines, and support the continued use of diesel carcinogen factories, you may well be.

 

Doesn't appear to be much different to me.

 

The BMW V8 TT is a hot vee and it came out before the Mercedes engine. It's not "rubbish," but doesn't sound as good as a supercharged engine because the turbos are on the exhaust side. I've had several versions of the BMW 4.4 turbo engine they were all very good with no reliability issues.

And turbocharged engines are not inferior to supercharged ones as far as performance goes, because they provide a very wide torque band. If someone really thinks they are inferior, the engineers are Porsche, McLaren, Ferrari, and Nissan would probably disagree.

 

Turbocharged engines ARE inferior due to uneven power delivery. They all suffer from turbo lag (delay it takes to deliver full power when going from partially closed throttle to wide open throttle) and they also have very uneven torque curves (power available at lower RPM and higher RPM is drastically different, this is often called on-boost off-boost).

There are many technical "solutions" to these problems, and on an automatic gearbox twin-turbo engine these are largely masked from the driver. With this configuration, in everyday street driving, these may not even manifest.

On track, I would rather not deal with managing RPMs of turbo engine. You have to worry about partial throttle transitions causing on-boost off-boost transitions. More so, compressor surging severely punishes lift-off, this detracts from optimal use of brakes, as you want to avoid transitions from WOT to closed throttle.

 

I like my supercharged V8 F Type,
I liked my twin turbo charged 3.8l V6 which produced the same output as my F Type R.

Anyone who wishes to believe that modern turbo charged petrol engines are inferior to supercharged petrol engines could perhaps explain why in both on road use and track use the vast majority of forced induction high performance petrol engines use turbos ?
Maybe all the engineers are less knowledgeable than the supercharger fans .

All that stuff about turbo lag should be left were it belongs in the 1970s to 1990s . Maybe explain how to get comparable efficiency from superchargers and significantly reduce the power consumed to turn them.

 

Does Jag have plans for a 6cyl injenium engine? The 2L 4cly is making 296hp/295ftlbs in its first release so it’s easy to imagine a 3l 6cyl around the 500hp mark.
