Hi All

Potential F Type buyer trying to educate myself. I have not been able to find this information anywhere so apologies if this has been covered. If so please point me in the right direction.

My questions - What are the differences between the 2 V6 engine versions? Looking at 2015-2018 models in particular. I know one is 340hp in the base and premium versions and one is 380hp in the S model.

So do the two versions have different internals, boost, tune?

I see lots of tunes and options for the S model V6, is there anything available for the 340hp version?

Thanks All

Scott

 

Same engine, just different tuning.

The S has a mechanical LSD, adaptive dampers, bigger brakes, bigger wheels, and a few other minor differences.

 

Gooday Scott. The engines are a different tune. If you have a 340 and tune it, it will take it to the same level as it would the 380. So the VAP tune takes both to 400 (which is the same as the p400 version of the F Type, probably my favorite of the unmodded 6's) and the VAP Pulley and tune takes them all to 450hp.

The v6S has a lsd and bigger brakes standard, and needs at least 19 inch wheels for the brakes. The S also has the adjustable suspension standard, which is probably the thing that would matter the most to me as the "standard" ride is a bit softer than the ride in the base. That said, once the seats soften up and with better rubber than the stock P Zeros, the ride is comfy even in firm mode, so even that is salvageable in the base as long as you dont mind throwing a bit of money at tyres. I run mine on forged 21's and drive in the dynamic (firm) mode most of the time, the ride is beautiful for a sports car.

Edit - oops, I said what Luc said but longer!

 

2016 is the sweet spot for the V6 models. Almost every option was standard...glass roof, upgraded Meridian Audio. 2017+ is when JLR started charging for every option.

 

There are very little difference between V6 340 and V6S 380 tunes as it all in the high RPM range that you don't experience during normal driving. The major difference between V6 (340) and V6S (380 and 400) are non-engine components. As others mentioned V6S comes with a limited slip differential - this allows you to put more power down, as rear wheels struggling for grip when pulling from a dead stop is an issue. V6 that comes with an open differential is very prone to one-wheel burnouts. This matters less with an AWD F-types that became the norm in later production years, but with RWD F-type you need LSD to put all of that power down. There are also other nice-to-have features as controllable active exhaust and magnetic adjustable dampers but all of these are generally aimed at adding comfort and not performance.

I was in the same boat as you this past summer, after way too much time on this forum I finally decided on an S. The S (over the base) is usually optioned up with extras, I wanted the LSD, performance seats, steering wheel, performance brakes, vision package, auto wipers, headlamps and high beams etc. On the base versions those options are hard to come by, I knew going in that I would install the VelocityAP tune and pulley, without a limited slip differential I would just be spinning expensive tires. Eventually I found one with all the options, low miles and 20" Gyrodyne wheels. Good luck with your search!

 

Just on the point of some cars having a LSD ( limited slip differential ) which models have it.

 

All the V8 cars have electronic LSD.
All V6 cars have mechanical LSD except for the base 340 hp model. The I4 cars don’t have LSD.

 

On a related option, I think that Torque Vector by Braking was only available on the V6S in combination with the Super Performance Brakes. My memory may be off, but that's what's bubbled up from the depths.

 

That is correct. I had no clue about the TVB or even the Super Performance Brake option on the V6S when I submitted the order on the car. Fortunately, the sales manager I was dealing with arbitrarily added that to my order sheet.

 

My build sheet shows High Performance Brakes with Red Calipers, LSD with Torque Vectoring.
Perhaps a UK thing?

 

Maybe a US/UK thing, maybe a 16/17 thing. I had a lot of time to play with the online configurator between the time 6MT specs were available and when my dealer got an open slot. It took forever, but gave me opportunity to stare at different wheels. I did not remember that CCB were not available for the 6MT, likely because I never seriously considered them given the cost, but I do remember that the TVB was tied to Super performance brakes. My suspicion at the time was that the larger rear brakes were tied to it to keep heat under control, but that's just conjecture.

 

It works great on the track and I love it, but in everyday driving I don't see it ever activating unless you are doing something very very stupid.

One interesting quirk of this system - if you have TVB and don't put car into track mode, the combination of TVB and DSC intervention can result in premature brake fade. So don't forget to put DSC into track mode (3 seconds) or completely off (10 seconds) if you plan to drive ***** out on the track.

Otherwise, DSC is excellent on F-type, I really like how it is implemented. It shows that JLR engineers spent a lot of time on the track fine-tuning F-type. Kudos to them.

 

Interestingly, larger rear calipers were not offered with SPB until later years. In my 16 I have super performance brakes with larger front calipers. It is straight-forward retrofit, but I honestly don't feel that existing brakes are deficient in any way or form and dragging my feet on doing the swap. I also have TVB.

 

Are you certain you don’t have the larger 376 mm rotors in the rear? I do on my MY16 with SPB & TVB.

 

Well, now that you mentioned it, I never measured them. However, they look very unsexy so I assumed they are vanilla calipers. Unlike fronts, that look the part.

If you have 376, can you post a picture of yours? My car is in offsite storage for the winter.

 

There were four levels of brakes in 2016:

CCB - can't remember the sizes
Super Performance - 380mm/376mm
High Performance - 380mm/325mm
Performance - 355mm/325mm

My recollection remains that Super Performance was tied to TVB. I'll see if I have any pictures from before the upgrade to two-piece rotors.

 

The rear calipers are certainly pedestrian looking.

 

Yes, this is how I recall my rear calipers look. I will measure them in the spring to make sure.

Also, not at all smooth surface and hard to keep clean because of that. Yours look much cleaner than mine, how do you keep them this clean?
