    Traction also matters more so than weight. Corner entry (weight/brakes) vs exit (power). Also where is the weight i.e. Low in the CG or high.

    These cars are not drag racers. They are built for track lapping times and public road driveability. Tons of much faster drag racing cars that wil crush all of these cars. Those will all get killed on track. This is about track times where power, weight, aero, tires, etc are all important. 720S will beat the ring times of these other cars and certainly any drag strip racer

    It's easy to build a fast straight line car. Go to any drag strip and view the cars that will run 6-9 seconds. But that's all they do

    Were did i qout anything about drage races..Dont get your point. I thought we speak about road legal production cars with official numbers..
    Having a 720s on order and spoke at Goodwood to mclaren, they said a ring time of 7:05 is likely, even they did not test the 720s as mutch as other brands (porsche) on the ring.
    918 had a 6:57 ring time, but on older tyre generation.

    It would be wrong to mix up ring times with other lap times. It is a complitely different lay out with mutch less grip and traction.
    I do not expect the 720s to beat the 918 on the ring but on other shoorter tracks like Hockenheim ring short circuit it could be very likely and i hope so..

    Sorry I was just making the point that some cars are built for track work and others for drag racing. The Tesla is a great drag racer but pretty sure it will get killed by even most mediocre sports cars on any track.

    I agree that the longer and less technical tracks with long straights play to the high HP cars like the P1, 918 or LaFerrari. We'll have to see how the 720S deals with that type of track. The GT2 RS is said to beat the 918 on the ring so it would seem if that car can do it so can the 720S. On the shorter technical tracks the 720S should have a field day against the 488 or the hypercars.

    And congrats on your 720S order!

    No way a 720 is faster than a 918 in a straight line or on a track.

    Let me know when you have actual proof.

    Of course! :)

    720S weighs 3128lbs (4.4 lb per HP)
    918 weighs 3602 lbs - 3692 lbs (4.06 lb per HP)

    That 500lb to 600lb advantage will make up in the corners for quite a bit and the power to HP ratio on these two cars is quite close. The 720S is more than 15% lighter. Not insignificant. Also as the 918 exhausts its battery that power to weight actually tips to the favor of the 720S.

    I'm sure we'll have some track numbers within the next month or two as these cars get out there. The 918 was built for ring times basically. Engineered around a sub 7 second time so all parameters were based on that goal ( a good one ). If the 720S doesn't top it at the ring I still believe the normal 1 to 2 mile technical tracks around the world it will. But again we will have to see. The 488 should be an easy mark though for the 720S.

    I think the 720S will feel like a wickedly fast car in a straight line, especially on track and at the same time much more livable as a daily driver than the hypercar set. Probably same as the 488 in terms of daily drivability. The 458/488's you could easily drive every single day and then tear them up at the track. The 720S should be the same but just faster.

    I'm leaning towards ordering the 720S instead of the 488 since the 488 is still a bit too familiar next to my 458 Spider in looks.

    There is a problem with your math:

    Mclaren 3128 lbs divided by 720 hp = 4.34 lbs/hp which is more than the 918?

    USA HP is 710 (not 720) but math might also be off on that. Would still be about 4.4 lbs/hp. Way more than the 918. Can somebody check my math and weights + HP numbers?

    Ok so here is what I found. 720S is more powerful per lb then the 918 weissach!

    720S is 553 bHP per ton
    918 Weissach is 540 bHP per ton

    Do you guys really think the 918 is going to be faster with MORE weight (500 lbs more) and less power? The rear wheel steer isn't going to make up for all of that. The AWD may make up for some so guess that is what we will need to see.

    For those interested..

    P1 is 584 bHP/ton
    LaFerrari is 599 bHP/ton
    Ariel Atom 909 bhp/ton

    First off, that alone certainly isn't enough to say whether a car will be faster around a track than another. Traction is always the limiting factor. Secondly, your math is off.

    720S is 1.42 tons (metric)
    918 is 1.65 tons (metric)

    710/1.42=499 hp/ton
    887/1.65=537 hp/ton

    And that's if you think the 918 is making 887 hp. Lot of evidence suggest it's pushing close to 940 in hot laps mode.

    Also, the torque differential is massive and that's what pulls a car out of slower corners.

    I'm not bashing the 720S I think it's insanely fast, but Buddyg is likely correct.

    well it's about as basic as math gets not difficult to calculate.

    The new GT2 RS has about the same price with 488 or 720S or Performante. I think Porsche is being over confident. Let's see if the demand is good.

    This car (720) is growing on me. I saw it in person and its nice. I still dont like the eye sockets but am intrigued by the performance and power. The unknown about the depreciation will ensure that I will wait a year or so before adding one to the stable.

    I cant have an endless amount of cars but the 488 stays - love it too much- my other exotic is an SLS. Im likely going to move that in a year or so.

    My hesitation is do I get the 720 or Ive been tinkering with the idea of a F12. Prices on those are getting very tasty- especially by next year when the super fast comes out.

    In Australia the base price of a GT2RS is $645,700 - to put that in perspective the 488 GTB here is $469,988 and 812 superfast is $610,000. Even a turbo s is $461,900.

    Welcome to Porsche Australia!

    GT2 RS is sold out I'd imagine those coming on the market in the next years will have a crazy mark-up despite Porsche's hopes otherwise. Good luck finding one at less than twice the price of a 488 for the foreseeable future

    I drove the 720S and it has head spinning acceleration. I was impressed, amazed and left dizzy headed.

    I can walk into the 3 Porsche dealers here and buy one - Price has made it less palatable for most (me included).

    It's still available. Even the GT3 manual is still available. I think they will find it very difficult to sell a Beetle that has the same price with 488 or 720s or Huracan. The look is a serious problem here. The only thing that makes the GT3 selling like peanuts, is the NA engine.
    The GT2 RS' engine is basically 911 Turbo S with larger turbo. It only revs to 7,000 rpm and has 700 hp. Compared to 720s, it is over 150 kg heavier and 20 hp less. Even a 5 years old knows that 720s looks 100 times more beautiful than the Beetle GeT 2 Racing Shoes. And I bet the 488 GTO's price won't be far from this too. IMO, the Beetle is at least 25% over priced.

    In France the GT2 RS is about the same list price as a 812 (more than a 488 or 720S) - it seems ambitious indeed.
    Porsche has been surprised by the price people have been willing to pay for a 911R and does not want to leave money on the table, but they underestimate the facts that the R was a limited series and that it was presented as the last ever manual gearbox 911.
