Stopping times for cars?

[FastShow]

Any idea of a site that lists them? Or at least lists a sizeable amount of them?

[v8guinness]

Distances are usually considered to be more relevant... magazines I'm sure some still print times and distances from a few speeds.
Why?

For a completely pointless argument I'm having with one of the anti-speeding brigade over at another forum...

re: Highway code figures per chance, or quick cars having better brakes... 911's have particularly good brakes if you're after a good example...

From Autocar 0-100-0 test 2002

100-0

Caterham R500 3.44s
Zonda 4.05s
911 Turbo 4.28s
Murcielargo 4.41s
SL55 4.37s
Tamora 4.99s
EVO RS Sprint 4.35s
RS6 4.35s
Impreza STi 4.25s
Elise 135 Sprint 4.32s
Focus RS 4.32
Cupra 4.39s
Civic Type R 4.43s

All pretty similar, though I do remember reading a quote that said Porsche 911 Turbo 70-0 in 69 feet, now wipe your internal organs off the screen

Don't forget reaction time 0.35 seconds

Just guessing - are those
0-30-60-100-think-0 times?

[v8guinness]

Guessing thats 0-30,60,100,0... (mph)

[v8guinness]

Doh, beaten... thinking is between 0.5 and 0.7 seconds for a true reaction, anything better is pre-emptive, i.e. second guessing...

[FastShow]

What are the highway code figures for the same? Just for reference.

Yeah, I was editing as you wrote.

Tuscan's fast innit!

[v8guinness]

TVR fast... learn somehting new everyday!!!
Seriously, light weight and plenty power is the way forward... Ultima would be interesting too...
Roadcraft only mentions distances, and suggests learning your car rather than trusting whats in a book, my Highway code isn't handy at the moment.

Highway code stopping distances are

d = s + (s*s/20)

where d is in feet and s is in mph... except they went and changed it all to new-fangled metres and such

A bit of number crunching (clickety click) gives:

Thinking time 0.68s Stopping time 6.81s total 7.49s

Quite a bit more than the Autocar figures.

[FastShow]

Excellent, many thanks to everyone for the help.

[v8guinness]

Does it give times? (I forget)
If not how did you work them out???

Some old figures (the original Autocar programme, approx '93?). Braking only, no reaction times:
7JPE: 4.11
LCC Rocket: 4.68*
911 turbo: 3.92
Viper Venom600: 4.06
F550 Maranello: 3.89
Cerbera: 4.03
XJ220: 5.99
AM Vantage (the old style): 5.70
M3 (Series 2): 4.32
Caterham 21 Supersport: 4.35
Early Elise (118bhp): 4.54
106GTi: 4.34
Bravo HGT: 4.96
Honda Fireblade: 5.46
Superkart: 3.82
AM DB4GT: 5.4
AC Cobra (modern Mk4, 302 engine): 4.14
Mondeo GLX: 4.67

*In its defence, the Rocket stopped from 108mph, and due to a dodgy rear damper had one wheel flapping.
Gossip has it that the Caterhams tested are "rather well factory-prepared"
