200mph and front wheel drive? I presume its been done?
Discussion
Inspired by the guy who has the rx7 build in the readers rides sections wanting to do 200mph for 10k, I began wondering if someone had done 200mph in a fwd car, but having quickly googled it, i couldnt find any evidence of it. Google didn't even throw up an bonneville style stuff. Does anyone know of a 200mph front wheel drive car? If not, how would you do it?
The new focus rs supposedly does 173mph iirc, and it cant be particularly aerodynamic with all that fibreglass hanging off it, and there was a smilarly paced vecrta if i remember correctly, so what about a calibra/cougar/mx6/406 coupe? How much power would it require to get one of these to 200mph? i presume someone on here knows how to do the maths, given the drag co-eficient?

Would be very difficult.
read here about 200 4WD and see how much power is used.

Why does the driven wheels being front and not rear affect it particularly?
doesnt as such, just wondered if it'd been done.and the post below yours shows it has been done.
Now, what would it take to do it in a road car!
I presume the calibra has the lowest drag coeffcient, since everyone raves about it. That civic had 560wheel bhp.Calibra, Smooth underpanels, taped cracks, tiny wingmirrors, narrow tyres, 600bhp custom gearing for exactly 200mph on the limiter?

The Andrew Gallagher Focus using a wedge front end & 680bhp reached 196.6mph within the confines of Brunters its 4X4. The Fiesta mentioned did 179.0mph with a tad under 500bhp again at Brunters. Lots dream & wish to do 200mph there but only a handfull ever have im afraid. Dreams & reality are serarated by having to 'do it'.The Civic probably had 3 or 4 miles to reach 200mph a different ball game in the UK when the longest straight that can be used is 1.7 miles.

Would there be any issues with gearboxes? Obviously less room to play with at the front the big issue for getting the power in there.
I don't see why it would be a problem. You don't need any more gears to increase the top speed (if you have enough road to play with) and the strength of the gearbox seems to be more determined by the materials used in its manufacture and the quality of the parts than its physical size.

Plenty of production cars do 200MPH+ now, I don't think you need 650+ BHP to achieve it.
Maybe 500+, but some of that's down to gearing and aero and although most FWD are a little constrained packaging wise compared to a mid or rear engined car, there's no obvious aero advantage to RWD front engined over FWD front engined.
On the other hand, if you want a car which will JUST do 200MPH you can do a lot with aero and gearing to get you a lot of the way there. Lots of FWD cars can do 150MPH, making one that could do 200 can't be that hard if that's ALL you want it to do - Most supercars, though, are required to deliver awesome acceleration to high speeds, too.

I think its pretty obvious there is a MASSIVE difference between 150 and 200mph, if you stick with a standard road car shape then as mentioned above it is the aero of being slab fronted that makes it so hard!M.
I would hazard a guess that given a Fiesta with over 500bhp can only really make 180mph then to get another 20mph would require a lot of aero and a LOT more power!
Hence my comment that you could do it easily if that's ALL you want it to do.
You would need to focus heavily on reducing drag and fitting long gears, but not ALL FWD cars at shaped like the Kia Soul...
The RS Focus is reckoned to do 163 (maybe more) on just 300 BHP - 40 more MPH with a lot less weight, longer gearing (JUST for max speed) and improved aero would seem quite feasible, although it wouldn't do 0-60 in under 6 seconds or be that practical on a day to day basis I suspect.
Read the link about the 200 MPH Civic - That's basically what he did and it DOES 200+...
