i was enjoying my second beer at the oyster house when i thought i heard someone say that redline in 2nd gear will get you past 60 mph, and that they were actually seeing 0 to 60 times in the high/middle 6's but 1/4 mile times required a 2/3 shift so are more in line with expectations.
BTW, thanks to whoever picked up the tab at the oyster house

Yes. They said that you could achieve 0-60 in under 7 seconds in 2nd gear!

someone explained 0 to 60 to me this way-


First, there is 0-60, and there is 0-60 "compensated for rollout" which is close to what you would get if you went to a drag strip.

The compensated is generally assumed to be 0-60, but it is really IVM [Initial Vehicle Movement] - 60. It is the time from when the vehicle has moved 1 foot to the time it reaches 60 mph.

True 0-60 is about 0.3 seconds longer (that 1-foot takes 0.3 seconds) than IVM-60.

Most magazines report IVM-60 but call it 0-60. Automobile Magazine, IIRC, reports true 0-60 and their times tend to be about 0.3 seconds longer. So, Car and Driver reports 7.0 seconds, Automobile reports 7.3, but they are actually reporting on the same car.



Now, IVM-60 is usually gotten off of a 1/4 mile run. The upshift from 2nd to 3rd occurs very close to just past 60 mph. In order not to mess up the 1/4 mile run, you have to be careful to upshift at just the right time - and that may be exactly where the computer is trying to pick 60 mph.

for example- given IVM-60 ranging from 7.0-7.3 seconds.
IF you just run the car up to redline in 2nd gear (just above 60 mph)
you will have IVM-60 range of 6.7-6.9 seconds.
HOWEVER, this is not how magazines actually do it, nor is it a real test of 0-60 (IVM-60) times - just more of academic interest.

CDB did you forget to log off "wife of CDB" again?
Looks like you are going to have to get "wife of CDB" her own computer :)

Dear Gentleman,
When I wanted my own post, I thought "wife of cdb"was amusing.
The information I posted was segments from a PM that arrived in my mailbox from a GM engineer. I passed it along because I thought you (men and women) might be interested because it explains the difference between the official 0 to 60 and what came up while chatting with the GM engineers. If you want me to share with you in the future try to be a little more respectful. Ask Terpfan what happens when you get on my bad side!
Don't make me call Lori!

They taunt us by putting an 8,000rpm line on the car... but the fuel shutoff is at 7? Booo....

They could have at least made the fuel shutoff at 7,500.

The Sol redlines at 7000rpm.
i asked about the rev limiter and the engineer who was my test drive escort told me to floor the accelerator while parked to demonstrate. i'm pretty sure that it limits at 100 rpm over "red line" and for some reason i recall that the tach pinned at 75-7600. my recollection may be faulty- maybe we can get a little help here?
(edit for addition) 177hp @6600 rpm according to pontiac...but that may not be red line.

Well, the tach is labeled to 8,000... but the little redline bars get thick starting about 7,500.

Oh yeah? Well the solstice goes to 8, and my Benz goes to 80!!!

...cause it's x100. Crazy Germans.

If only we could of got it up to 60MPH...anybody else who had the test drive, find the initial hesitation disappointing??

elaborate please!? :confused:
Maybe it was just me...but that first fraction of a second, nothing happens...then the acceleration kicks in...Guess I have to remember it's not a high and sports car.

As I have not read anyone else saying so...thought I would bring it up!!

It's not a BIG deal, I loved driving the car, felt GREAT to sit in,and you will love it too!!

Ac

I realized after that the AC was running during my test drive which must have robbed some power from the acceleration possible.
I used to turn off the AC on my Del Sol sometimes when I was just starting off from a light or stop and then turn it back on when I got cruising.
It made a big difference in the Del Sol and in fact I now remember it used to hesitate a bit with the AC on when I first accelerated.
