3R's top speed?!
Discussion
Just means that the peak/maximum power is produced at 6200rpm after which it drops off slightly but the engine will continue to rev to 7200rpm therefore still pulling all be it at at less output.
For normal driving other than outright top speed there is little point in exceeding 6200-6500 rpm through the gears as no more power is to be gained therefore you are better to change up and use the torque of the engine.

The fact that peak power is obtained at 6,200rpm yet the engine revs to 7,200rpm explains why the top speed isn't the 191mph that the gearing theoretically allows.
The top speed in this instance is limited by the power available to overcome all of the losses preventing forward motion at these speeds - predominantly aerodynamic effects and drag. There is an equilibrium point at about 6,520rpm where the (tailing off) power can't accelerate the car past 173mph.

Scientifically tested by my GPS at Bruntingthorpe she pulled:
153 Wing on into a 25mph headwind
157 Wing off into same 25mph headwind
160 Wing on into a 10mph ish headwind
Putting the low figures into context, DAZ's 996TT only managed 173 the 25mph headwind day. His same car ran high 180's with less headwind.
Top Speed is pub talk anyway. The Noble is one of the quickest cars out there 0-115ish, after that my Jag would out-accelerate it! (OK, so the Jag is a 405bhp V8 Supercharged monster
)

Its all pub talk Danny, acceleration included.
Evideneience I would like to present to the bench is
"Good to see that the Audi barge was second quickest on the list, missing out to the blown Porker by only 0.1 sec on the 0-60 dash."
This inital exhibitiatioion of his factination with the 0-60 can be fully reference at the following, if m'lud will forgive me for using this new fangualed Internetsminternet speak, "U...R....L" of
www.pistonheads.com/gassing/topic.asp?f=23&h=0&t=82670
We then find later that again Mr niceywiceypants
"Objection m'lud - there is no need for that emelishment"
"Granted"
I'm sorry - Mr JeremyC then, at the following errul
www.pistonheads.com/gassing/topic.asp?f=23&h=&t=97102
My final eviedence, that I think will demonstrate the the jury that "pub banter this is not" is found here
www.pistonheads.com/gassing/topic.asp?t=52622
within which upon given the question by a jooly nice, innocent fellow called "Pete" asking
"That'll be 0-60mph with four wheels, roof optional of course......is it feasible?"
Mr J.C. replies "A Caterham or Westfield would get you there."
I rest the case for the presecution, Mmmmmmmm'lud

Now where did I say pub banter was a bad thing then.
I'm just as much a bore with the numbers as anyone else....
Now, wheres my pint.
