Like you say there is still a lot of weight you can take out of the car
Ditch aircon and sound system for 41KG saving
41kg Ditch aircon and sound system for 41KG saving
That sounds a bit high ? I thought maybe 10 for A/C and 10 for stereo do you have the stats on that from Mclaren ?

On the 675, it was about 15kg for aircon and 5kg for the meridien sound system.
I'm thinking these are two things (along with lift) which you really can't delete unless it's purely for track ?Interesting on the 675 they said the engine was 50% different (to the 650) this was always one of the lures of the 675LT for me, a really bespoke engine, I hope they do something similar for the 765, reconfigured blowers, even lighter weight pistons/rods, special cams and a useable 8.5K rev limit would be nice, if they just give it a "tune" it will have me teetering.

Personally aircon is a no brainer for me. imo one would have to be absolutely nuts to even consider not speccing it. Heck even GT racing cars have it nevermind a road car. It's actually farcical imo that it's offered as an option delete just to get the headline weight saving number...Interesting on the 675 they said the engine was 50% different (to the 650) this was always one of the lures of the 675LT for me, a really bespoke engine, I hope they do something similar for the 765, reconfigured blowers, even lighter weight pistons/rods, special cams and a useable 8.5K rev limit would be nice, if they just give it a "tune" it will have me teetering.
Well it's always hard to make out what's marketing and what's the true amount of changes that has gone into a car. Mclaren have let's be honest been quick to overhype some of their cars as well.. but ultimately I think it's fair to say no LT has been anything but a bloody good car to drive and in both cases, a significant step up in excitement to drive than the 'standard' car. There is absolutely no reason why the P14 LT will not be the same...

Given my understanding is that the Senna engine and transmission is mechanically identical to that of the 720s, why would they go to the bother of a significant re-work for the LT, it should be cheaper to buy new than the Senna? I hope I'm wrong (on re-work not price), but logic suggests to me that this will be the case.Interesting on the 675 they said the engine was 50% different (to the 650) this was always one of the lures of the 675LT for me, a really bespoke engine, I hope they do something similar for the 765, reconfigured blowers, even lighter weight pistons/rods, special cams and a useable 8.5K rev limit would be nice, if they just give it a "tune" it will have me teetering.

Your logic is sound and the 600LT motor was very similar to the 570 so you are probably right but......I like upgraded bespoke engines and the 765 should have more than a tune

I don’t know if the 765LT runs lower than the standard car and it may well have a more prominent front splitter, but I managed a cross country trip through rural France and Germany recently in the 720 when the only time I used lift was the rubber sleeping policeman at French customs on the UK side of the tunnel. Granted I left lift up for the train but doubt it is necessary. McL generally seem to run higher than Porsche GT cars.Interesting on the 675 they said the engine was 50% different (to the 650) this was always one of the lures of the 675LT for me, a really bespoke engine, I hope they do something similar for the 765, reconfigured blowers, even lighter weight pistons/rods, special cams and a useable 8.5K rev limit would be nice, if they just give it a "tune" it will have me teetering.
For my sort of use I can’t find that much to fault dynamically with the 720, I surely don’t need more power, and I doubt if any of the Playstation stuff I don’t like about the car will be addressed with the 765LT.
The issue with weight is what spec car is used as the base point. You have to consider that the Track Pack versions of the 570s and 720s are already allegedly 25-30kg lighter than standard so in effect the 600lt in standard form compared to a 570s track pack is probably only 55-60 kg lighter and if you specced more Carbon the 570 is more likely only 45-50kg heavier. This is probably why on road their is little performance difference in the 2. Of course on track a different case !!

Agreed, whilst I use the lift all the time I'm pretty sure it wouldn't scrape even with it down, I have actually NEVER scraped the bottom of mine in 10K miles, can't be said of my 7GT2 which regualrly scrapes the front despite my best efforts.lowndes said:

Agree with this as well, it is hard to see how they can improve on the 720 unless they really push the boat out.Rocketreid said:

This is true, one thing I am hoping for is a proper anorak session with a knowledgable Mclaren engineer to see what the real weight would be for my ideal spec LT (I'm hoping to get this at Geneva) which will be a crucial factor in whether the trigger is pulled (assuming allocation is offered)

That's the bit i cannot get my head around.
The 'basic' 720s is just so ridiculously capable, so what can they possibly have up their sleeve to turn the volume up to 11?
It will be a few small improvements , a little less weight, a bit more power and improved aero. The 'basic' 720s is just so ridiculously capable, so what can they possibly have up their sleeve to turn the volume up to 11?
Which all together will add up to an overall far superior track package.
Like most I can’t see too much benefit on the road as the 720s is far too rapid and sublime with it !!

If you drive a 600LT and 720S back to back, which I've done a couple of times, you can see where they can go with this. Basically speed of the 720S with the feedback and touch of the 600LT.
Agree, my guess is the delta between the 720 base and LT will be the same as the 650S and 675LT. 355spiderguy said:
You can't help but wonder how where this leaves the Senna with its very challenging looks and very high price tag.
Going by classifieds and the trickle of Sennas with very low or delivery miles that are appearing it maybe seems that owners of a Senna that have been allocated a 765LT may be offloading?Is the configurator up?
Looking forward to playing with it and see it in the flash. New colour reminds me of my MSO Helios Orange, I think overall they've nailed it, sounds and rawness vs 600LT still to be understood, I bet 600 is less insulated and more raw and connected to the road thanks to non hydraulic suspensions.
