So it's whre it's FLAT that it's usable.
Hence why I'd asked you to invetigate and realise that the revvy I4 had a wider band which makes it - when mated to a gearbox
- to have a more usable power band.
Yes, and if the elise truly had a usable powerband its rolling start wouldnt have been close to 2 seconds slower due to no low end power. That can also go for the S2000 tested in the same article, thanks to no low end power it did close to 2 seconds over its 0-60 time with a rolling start.
Like I said, if a car has usable power, then it has power in its low and high rev ranges.
Take the GTO C&D tested, it did 0-60 in 5.3 seconds. Rolling from 5-60 it did 5.8 seconds, thats only 1/2 a second. Why? low end power.
That last comment is nonsense, Slicks.
Go listen to a race car start - a flagged start, none of this rolling start stuff
Rolling starts give an idea of how much low end torque the car has. Race cars are a totally different car than street cars. One thing about race cars is usually displacement is limited due to rules. So, revs will have to be used to make the most amount of power from that amount of displacement.
Revs to max point and GO.
Sure in rally they have AWD...
Traction isnt always in issue with these race cars, having racing slicks and in some cases a traction control system. In street cars traction is an issue, thats why cars like Vipers and Corvettes are launched at low RPMs. Yet thanks to their good power bands they pull of great 0-60 without being launched at redline.
AND that shows HUGE bias as you've clearly never driven a car with it and realised that it is NOT that hard to do. have you ? If you name the car we can probably talkk about optimum launch. I've done thousands of race/rally launches, IF you'll take it as true when I describe it I'm happy to explain further.
Never driven a car with a "high redline" with peaky power, is that what your asking? I drove a Celica GT for example, not exactly a "high revver" but it was a manual and I launched it at about 4500RPMs. Bad idea, torque steer, and alot of wheel spin, but like i said its a street car, not a race car.
That "stupid calculation" is used by race engineers to optimise the car for racing at a track !
So who told you it's "stupid", because it flies in the face of what happens every day in tracks and pits all over the world !!
Race cars again are different from street cars. Like I said before, displacement is limited bla bla bla. When racing they're going to try their best to keep it in the high revs, where they make their power.
And yes, that calculation is biased toward high revvers.
You are stuck thinking on justifying the whle power badn having to be flat!!
Think of the car IN a gear approaching a corner, the wider the usabale power band - ie power that dos not drop so much that you lose perfromance - then the more scope the driver has to avoid a gear change mid corner and hence the FASTER they will be.
Very good, now think about an Elise coming out of a hairpin, its a 2000RPMs, next to it is a Z06, also at 2000RPMs, which will accelerate faster? The one with usable power, the Z06, although having a power/weight advantage, has alot of torque at 2000RPMs, where as the Elise, does not.
With a 2000 rev power band they can only adjust speed by HALF as much as a 4000 rev power band without losing time. The gears are what enables the driver to chose one so that the power band is most usable for the fast corner.
Yes, and wouldnt it be nice if the engine had enough torque that you could get away with a higher gear? That means it would be even better in a lower gear...
ah, well we went round that point SOOO many times and we DID go over the relative nature of these. AND we went over the physics of race car development AND we covered the issue of the types of roads AND we've covered recently the issue of driver awareness due to position in the car AND we went over the changes for the European version to "improve it's handling" AND we got personal about AND we got facts AND we got evidence AND we presented AND you ignored it all.
No, I saw you finally try and answer that one, good job. Now remember not say that the Corvette and Viper cannot handle, ever again. But yes, you are allowed to say that the Elise will out handle them, but does that make them bad handlers, certainly not.
