    omg that ariel atom is fast! it is almost head to head with the GSX-R!!

    i'm glad to see the noble is 3rd in the list (how's that for a "kit car" for those who don't really like it?)

    I don't know about you, but I like those "silly cars"

    Sort of embarassing that the 997S loses to the EVO that costs 1/3 as much (they handle well too).

    The real stunner is the 4000lb. M5 beating the 911S in the braking department!

    Is that the full list? they usually get a few more high end cars

    And a stock Gixxer beats them all!

    I find the 997S braking times strange since thats the 997S' strong part, the 997S brakes in shorter distance than a previous 996TT for example... and you know 100% sure there is something wrong when it doesn't beat a 1800kg front engined sedan in stopping distance, its a matter of simple physics.

    Are carbon brakes standard on the S? If not, that may explain the difference.

    They are not.Porsche offers PCCB - Porsche ceramic brakes
    as a 8K option.

    The BMW might out brake it, but not for too many times!

    That's exactly right. One stop from 100-0 is not very telling, since the brakes aren't even warm yet (a necessity for some pads to have good friction). Would be interesting if they did 10 tests (both on the acceleration side and braking, since heat soaking negatively affects some motors pretty badly too)

    I don't believe it would make much difference in a single stopping disctance test since both brakes (the red Turbo's steel brakes and the PCCB's) are enough to lock the wheels and bite just as hard, the difference between them is the supersior resistance to fade and temperature of the PCCBs compound in prolonged use and diffenrent pedal feel.

    PCCB brakes reduce unsprung weight greatly. Which would explain how a PCCB equipped 911 outperformed the CGT in a previous test.

    Re: Autocars 0-100-0 challenge

    the noble's brakes are too small IMO! compared to my porsche it must be half the size.. i'll take a pic and show you why i think so if they just put a bit bigger calipers etc. it will outbrake all of them!

    Re: Autocars 0-100-0 challenge

    The Noble is also half the weight of the Porsche so it needs much less brakes, because the problem with larger brakes is that it increases unsprung weight, so excessive brakes can also be unecesarily detrimental to the handling if it doesn't bring a significant braking advantage, if its doesn't need those larger brakes. Do you feel they fade quickily or don't have enough bite?

    Re: Autocars 0-100-0 challenge

    true carlos, but i still think they should've been a "tad"bigger. no fade so far and i've driven the thing pretty hard, but i haven't tracked it yet and that will be the ultimate test for the brakes.

    Don't forget the variability in time of moving the foot from the throttle to the brake pedal.....

    Very true. However, the formula for calculating the amount of heat energy that a braking system needs to dissipate is

    Mass x Velocity^2

    So if a car weighs half as much and velocity stays the same, then you only need to dissipate half the heat. But with a car that is half as heavy, you can usually generate much more speed before the braking zone,so this really increases the amount of heat (twice the speed = 4x the heat).

    In general, lighter cars need smaller brakes (and benefit from the reduced unsprung and rotating mass), but don't discount the extra velocity

    They use their left foot to brake. But there is still a difference reaction times.. ranges from 0.08 to 0.51 - most of the top cars are in the 0.2-0.4 range

    Good reminder Grant, the speeds at which the brakes are going to be working depending on the car's perfromance is another factor to take into account as well also, so true.

    Thats my point, the fact that the 997S was fitted with PCCB's that have less unsprung weight than the steel stock ones as you mentioned, does not explain why it beat the CGT in braking, since the CGT has the PCCB's as well.

    The 911 has a rear engine, therefore, it has a greater rear weight bias and, thus, it will exhibit less nose dive under hard braking.

    An F1 is a bit out of budget or street-legality here

    I did see the video, unfortunately they chose a V-twin sportbike for the test for some reason instead of a much faster inline-4 still once the F1 is at speed, it will reel in any bike, even a "turboed Busa with a lengthened swing arm" at some point, then again a Formula One car isn't precisely street legal

    Yep, thats one of the reasons of the legendary 911 braking
    However, the tires are also a great factor in braking distance and the 997S with PCCB's not only beat the CGT with very similar rear weight bias (40-60, though mid-engined) but much wider and specially designed PS2 tires, but also beat the GT3RS with R-compund tires... so still very surprising times for the 997S, at least to me.

    I think the GT3RS would've won if its R-tires were up to temperature. R-tires are very slippery until they get hot...
