    • More weird 911 Turbo test inconsistency? 2014 Porsche 911 (991) Turbo S cabriolet acceleration and curb weight figures from Car and Driver - 11.1 @ 124

      The 991 Turbo and Turbo S continue to show numbers all over the place in tests. Why is this? Conditions? Fuel quality? The computer pulling timing? Who knows, but the numbers are everywhere from 123 miles per hour in the 1/4 mile from MotorTrend to over 130 by Car and Driver recently.


      The 911 Turbo S convertible obviously weighs a bit more than the coupe at 3741 pounds. Car and Driver weighed the coupe version at 3590 pounds so the difference is 151 pounds. That is not nearly enough of a weight difference for a trap speed spread of 6 miles per hour.

      Making this more perplexing is Car and Driver themselves earlier got a 10.8 @ 126 out of the Turbo S coupe which certainly is about the difference one would expect 151 pounds to make versus the heavier convertible going 11.1 @ 124. That also was the fastest time out of any major US magazine up until recently when the Turbo went against the GTR and Z06.

      To further muddy the waters Road and Track tested the Turbo S coupe at 10.9 @ 124.4 with a curb weight of 3600 pounds. So how in the hell does Car and Driver suddenly get a massive acceleration spike when the Turbo S is being compared to the Nissan GTR and Corvette Z06?

      You figure it out. Because we certainly can't.

        They should at least provide consistent test numbers but this stuff is all over the place.

        4.1 seconds 100 - 124.1 mph is insanely slow given the front end times and 10.8 secs 100-150 mph wtf ?

        If you look at the previous traps achieved the 991 slows down quite a bit past 100. I don't know why. I just assumed it was the ECU pulling timing but I really do not know.

        doesn't have to do with power but in regards to weight, I just put my GTS on the scales and was pleasantly surprised @ 3129 We put an F82 M3 (2 door M3) forget the right name but it was 3660!

        The F82 is called the M4 and wow that is really fat for a sporty coupe...
        Is yours a Cayman GTS? Or Carrera GTS? I am assuming its the Cayman if it is that light!
        I saw a cayman GTS the other day and it looked and sounded very nice.

        Here's the M3

        and no it's not a cayman GTS. It's a carrera GTS manual. Redid it because it was balanced the other day. Here's the proper balance / weight spec

        Oh wow, I just fell in love with the 911 GTS...the 911 turbo is so $#@!ing heavy and the GTS has pretty much the same power right? Just no PDK and no AWD.
        I am no expert, how does the GTS compare to the GT3?

        No no. GTS is a C2S with a power kit (has 430hp) and the wide body. Can be had with pdk or manual.
        Can be had with rwd or awd. Not a gt3 or a turbo.

        Regular C2S are weighing in under 3100.
        Gt3 is prob around 3250 due to pdk and rear wheel steering.

        Oh I see. I still think I would rather have a 3100 lb NA 430hp than a 3600+ lb turbo with 513hp

        The GTS comes as a 4S too though.
