    Re: AMG GT R

    Kaizu:

    Not really, from Wikipedia for example:

    "Curb weight (US English) or kerb weight (UK English) is the total weight of a vehicle with standard equipment, all necessary operating consumables such as motor oil, transmission oil, coolant, air conditioning refrigerant, and a full tank of fuel, while not loaded with either passengers or cargo."

    The DIN kerb weight in particular that is referred by the factory has all fluids and fuel tank at 90%.

     

    We know Porsche always publish the real DIN weight, but other manufacturers use a different metric, Ferrari for example always uses dry dry dry weight with nothing inside the car and all lightest possible option, so is McLaren. Is Mercedes doing DIN or their own measurement?

    Re: AMG GT R

    Yes, Mercedes materials say 1555 kg is the kerb weight according to DIN. With 1630 kg being the kerb weight according to EC, including driver 75 kg.

    It's really nothing dramatic that cars end up heavier than advertised, I just thought the spec car had all the lightweight goodies and Mercedes is not offering (or is it?) air con, and radio delete packages (or is it?), so I thought it would be closer to advertised figure.

    Btw. I would be wrong on this if for some strange reason the magazine has measured kerb weight with driver included. Who knows but I doubt as it's called kerb weight for a reason.

    Re: AMG GT R

    I really don't understand the obsession with weight among amateur drivers. I understand it for pros who making a living driving but a run of a mill driver? Come On! You really need an inflated ego to strip down a car so you can go around a track two seconds faster. It would be like doing the Ring in 8:05 instead of 8:10. Is it really something to brag about?

    It seems to be faster on one track but maybe you can get one, I come with the R8 and we can try again. 😎

    Seriously: It is definetely a fast car but straight line, it can't harm the R8 and on the track, well...it comes down 90% to driver skills anyway, so I'm not worried.

    Btw: It was Markus who doubted the peformance of the GT R but since this is a press car and AMG has a "history" with press cars...well...why don't you get yourself one and we can try?! 😉

    I have to agree with you on this one. I won't tell my own stories because Mr. Sarcasm and Mr. Hipster won't believe them but I saw Walter Röhrl "destroy" a couple of seriously modded GT3 on the track in his(!) 911 Carrera 4S. 😜

    Re: AMG GT R

    In the Autobild video (done in the context of the above test) they also take off the wheels and you can look at the tires. For whatever reason these tires in the test are (still or again) different from those tires you can see on those very few test cars that are offered for sale on the internet Smiley

    In summary, what we know now is: in a straight line the GTR is slower than its competition. On the track the GTR is quick - but we only have lap times done with non-standard cars on non-standard tires. Chances are that the real cars, i.e. those delivered to customers, are slower in the straight line AND on the track. I would not order one under the assumption it might be quick. Of course, the pricing is attractive and one could consider one if one liked the design and would still like the car if it was outperformed by its relevant competition Smiley

    Kidding aside, I'm very interested in the GT R as a product (don't really care how quick it is). The only thing I'm worried of on the basis of earlier GT's and GT S's is the horrendous depreciation. But given the current demand for the GT R that might be less of an issue with this model.

    Yes...  

    You can mod a car as much as you want but in the end, it always comes down to the driver. So instead of wasting tons of money for chassis mods and whatnot, you better put this money into serious track training.

    The question is only: What for? If you want to drive in the Porsche Cup or similar events, OK but for some track fun on weekends, a standard car with semi-slicks will do as well. Usually these harmless events are a lot of fun with friends. Unless you have the time and money to do proper training for whatever reasons. I would never get into professional motorsports again, it is a waste of time and money if you don't do it right.

    Kidding aside, I'm very interested in the GT R as a product (don't really care how quick it is). The only thing I'm worried of on the basis of earlier GT's and GT S's is the horrendous depreciation. But given the current demand for the GT R that might be less of an issue with this model.

    Not sure that a GT R will make you happy but there is always a depreciation risk involved. If you really like this car, go for it but keep in mind that a sheep won't become a wolf just because it is badass. 😉

    Re: AMG GT R

    Sportauto now published the Hockenheim test of the same test car they used for the NBR test last year.

    - Car has approx. 40hp more than customer car spec

    Two lap times:

    - 1.06,3 with the "special" Cup tires also used on the NBR

    - 1s slower with "normal" Cup tires

    - with regular tires (as supplied to customers): no numbers given...

    In summary, all this confirms the suspicions we had. A customer car with normal hp output and non-Cup tires will not be quicker than a turbo Smiley  In the straight line, the turbo is even quicker.


    Re: AMG GT R

    Since when do they engine dyno cars?

    Stick track day tires on your track day car and the number stands. Why would you want to track your car with crappy street oriented tires? We already know that the latest generation compounds are a massive improvement. No reason to think they won't be available for customers.

    IMO, the car does as they said it would initially. 1.06.3 is as quick as the 918.


    Re: AMG GT R

    Interesting, do you have more data about the Hockenheim test? Scans? The press cars I have seen have been with "M spec" Cup tires, "M0" markings on the tires. Are they the special tires or the normal tires? Which tires the customers get, according to catalogue only one option? Can you go and buy the better ones from a dealer or tire shop?

    I am thinking have the different tires something to do with some random silly new regulations? Smiley

    For example, perhaps car companies cannot sell a car with too aggressive tires due to silly regulations of wet performance, drive noise, or rolling resistance? That's why they couple years ago stopped producing original Michelin Cup tires, and started doing Cup2 with improved wet performance, but less dry performance. And could that be the case that bit similarly to this GT R you cannot order (at least yet) Huracan Performante with the sticky Trofeo R tires like the record car had, but only with Corsa tires? I guess you can buy the Trofeo R's from your tire dealer for the Lambo...How it is with Mercedes tires?

    Another silly thing I'm spotting increasingly is the different fuel tanks, why so many new cars have bigger fuel tank as a low cost option? Once again GT R has the option of 10L larger fuel tank for small money. Wouldn't it be more profitable for the company to design and source only one fuel tank and not options of say 65L and a 75L volume tank? Is this once again something to do with silly regulations thanks to EU or whatever that only x y z amount of emissions is allowed with a single tank, and the bigger fuel tank is not counted as it's an option... Smiley  Just a random guess Smiley

    I really don't understand the obsession with weight among amateur drivers. I understand it for pros who making a living driving but a run of a mill driver? Come On! You really need an inflated ego to strip down a car so you can go around a track two seconds faster. It would be like doing the Ring in 8:05 instead of 8:10. Is it really something to brag about?

     

    Weight is an important concept among amateur drivers who spend lot of time on race tracks. More weight causes more tire wear, more brake wear, and more suspension wear.

    And it's not only about the wear rate, also durability of the car. The lighter the car, the longer it takes for overheating of above mentioned parts, for example.

    A pro driver can do one fast lap with a heavy car but go and drive the same heavy car as an amateur for a track day and you gonna end up in problems. This is the norm on any track day. I am not saying 60 kg is anything critical, but the less weight the better. And when you speak about lap times, I think everyone would be happier with a car that does a 8:00 lap and weighs 1500 kg than with a faster but heavier car that does 7:50 lap (before overheating the tires...) and weighs 1800 kg.

    Great example (from 10 years ago, when the GTR did not have any updates), would you drive a 997 GT3 or a Nissan GTR as an amateur driver on race tracks? That's an easy pick to choose the lighter and slower car...

    Nothing but a professional set up engine dyno is accurate. 40 hp is just error in such high powered cars.

    600 hp car
    2% incorrect drivetrain loss estimate
    2% engine variance

    Now you're already possibly 7% off, which is 42 hp on a 600 hp car.
