Calm down...

What does BTG mean?

J

 

today, the nurburgring (nordschleife) operates as a toll road. the entrance/exit to the track is right in the middle of the main straight. thus, you cannot do more than a single lap without having to stop at the "toll booth" again. because of this, complete lap times cannot be recorded because the cars can never run the full length of the straight.
so today, laptimes are measure in BTG, or bridge to gantry. there's a bridge right before the first corner - this is where the timer starts. to finish, there's a small gantry (like one of those things where they mount the big signs over the freeways) after the last corner, and right before you get onto a massive straightaway.
anyways, most laptimes are BTG times; if they are, people DO quote them as BTG times. to estimate a complete time, the general rule is to add 23 seconds to the BTG time.
so the times DavidM posted are full-lap times. an 08:12 BTG (what the S2000 was clocked at) would be an 08:35 full, so it is significantly slower than those 911/F355/M3 times David quoted.

 

i said 08:12 BTG buddy. figure out what BTG means before you go off on me like you know what you're talking about...

lol, no need to get upset :-) I didn't know what BTG meant ... but then I'm not sure how many other people did so thanks for explaining it. Though, some of the times I quoted are very current and "Sports Auto" does seem to publish the 'full' N'ring laptimes ... how do they manage that?

 

sometimes, with the right connections or moneys, the track can be closed/reserved... porsche does it, amg does it for their Driver Training program, and i guess big magazines can do it to. but still, even if those times aren't actual laptimes, you can still figure out their BTG simply by subtracting 23 seconds - the standard accepted by pretty much everyone...

 

you can still figure out their BTG simply by subtracting 23 seconds

Wouldn't different cars cover this 'section' in different time? Taking the extremes, I would have thought that a 911 GT3 will cover it quicker then let's say a Civic ... no?

I would have though that a percentage (%) on top of the BTG lap-time would be more accurate ... something like 'full lap' = BTG + 4%.

 

that's very true; that 23 seconds is not precise at all - a YZF-R1 is a bit quicker than a Mercedes A160! generally, the 23 seconds is somewhat accurate, considering you're talking about a higher-end car like all 911s, the s2000, bmw's m cars, and of course the ferraris and tuner cars and bikes...

and yes, a 911 GT3 will cover it faster than a civic (and any other stock car); that car, driven by Walter Rohrl (porsche sr. test driver) set the official record for a production car. it was a sub-8min run, and that's the FULL time. very fast indeed.

 

Now they've got the Murchielago as well as GT2 to go quicker than the GT3. They did 7:46 with the GT2 and and 7:48 with the Murchielago.

The GT3 time is still 'up' there though ... 7:56 if I'm not mistaken.

 

oh... cool

 

Ahh the link is'nt workin.

 

Ahhhh...probably because this post is a few weeks old.
