Ash,
Performed experiments? That is exactly what the car manufacturers did, especially Honda. Why would they market 4WS if they found it did nothing but degenerate the quality of a car's cornering ability? The problem was that few customers understood the benefits. Four wheel drive and anti-lock brakes have endured similar ignorance; both were fitted to the 1966-1971 Jensen FF, a technological fanfare that was also a commercial failure (just over 300 built). Customers were ignorant to the benefits and bought the Interceptor instead (approx. 6400 built!).
4WS may achieve greater understanding by the public in the future, just as 4WD and ABS eventually found acceptance. It may be something other than a car that breaks the barrier. Shopping trolleys utilise 4WS after all! Thankfully, my beloved Preludes do not handle like one...
Just take a look at improved turning circles and cornering speeds to find proof of 4WS’s superiority. There was one car magazine in the US that, in 1987, claimed the Prelude 4WS was the fastest road car they had ever slalomed, faster than the contemporary 911, Corvette, 328 GTB. I imagine the Caterham 7 would have been even faster if they had trialled it but I will come to why in a moment.
Away from the world of facts and figures, in terms of feel, I would argue that 4WS makes for a sportier, safer, more responsive drive.
Another comparison would be to take two versions of one model of car (two Preludes, two Lagunas, or two 300ZXs), where one has 4WS, one does not and drive them back to back for a period of time.
Regarding the brilliant, evergreen Caterham 7 then; yes, is so very potent because it is lightweight, has a low centre of gravity and the suspension is tuned for maximum roadholding. No regular road car can compete with that, but then Colin Chapman’s design has never had to concern itself with space for more than one passenger, a luggage compartment, weatherproofing, crash protection, and so on. Perhaps one would be better off with a motorbike?
Obviously, a Prelude 4WS would never lap a Caterham 7 on racing circuit, simply because its mass is greater and there will be greater compliance in the suspension; it is a mere ‘road car’ after all!
The power-to-weight ratio issue is fascinating. Bugatti recently discovered that one of their classic, 1930s GP cars (I forget which one) could cover a hillclimb sprint circuit faster than the current Veyron. I presume that is because despite having 1000bhp, the modern car weighs two tonnes.
In addition to that, I can recall attending a historic car race at Castle Coombe several years ago, where a Lotus Elan Sprint and a Ford Mustang GT competed for the lead; the American had the power advantage, but the Brit was so light that it was the Ford’s superior under braking and when cornering. And the Lotus’ power-to-weight ratio also ensured that it did not lose out under acceleration either.
Would 4WS improve something like a Caterham 7? I would argue with an emphatic ‘Yes!’ but I cannot prove it, because to my knowledge it has not been attempted. One can only speculate on the end product. I am not in the financial position to experiment with the concept.
