The old Focus ST ( and 5-pot Focus RS ) was faster for the 30-70 sprint than the 4wd Focus RS so I cant see the new ST being slower
It’ll be the standing start runs where the ST will be slower than the 4wd RS - can’t see it beating the front wheel drive Focus RS times by more than the odd tenth either - both similar weight and power
I agree. It’ll be the standing start runs where the ST will be slower than the 4wd RS - can’t see it beating the front wheel drive Focus RS times by more than the odd tenth either - both similar weight and power
In terms of acceleration, 4wd is a disadvantage once rolling, due to the extra drag, friction and drivetrain losses (however small they may be, they are still there). In any reasonably powerful car, it gives a big advantage off the line, but once rolling, I would expect a 2wd car to be quicker, all other things (weight, power etc) being equal. This would also apply to in gear acceleration, or indeed any measure where the 2wd car isn't limited by traction.
If you take typical quarter mile drag timing, 4wd will only help in the first 60ft, and will hinder for the remainder of the run. Hence why the formula of choice for drag racing is 2WD (RWD) with sticky tyres.

I wondered where that claim had come from too and suggested that they maybe meant the old ‘old RS’ - I.e the 5-pot front wheel drive one.
That would seem to be more of a possibility as it weighed 1480kg and had 300bhp - turned in a 14.2 ss1/4 @101.
The last ST with 247bhp managed a 14.8@ 99
Both were quicker 30-70 than the last RS ( the 4wd one which was tested in the wet incidentally )
Autocar’s test of the new ST is out in a couple of days
Ford claim the in gear times for the MK4 ST are quicker than the MK3 RS - it's nothing to do with the MK2 5-pot.That would seem to be more of a possibility as it weighed 1480kg and had 300bhp - turned in a 14.2 ss1/4 @101.

The same applied for the last ST (247bhp ) against the 4wd RS - it was quicker for most in-gear increments.
An extra 30bhp in the new one is only going to reinforce the advantage

I am in agreement with that - it was the quarter mile claim in the article I found suspect .

With you now!The same applied for the last ST (247bhp ) against the 4wd RS - it was quicker for most in-gear increments.

I'd suggest the torque figure might be more relevant as it's about 50lbft up at least and I'd not be surprised if when they test them there's more torque than claimed. The Mustang 2.3 version now gets 350lbft, the MK3 RS was running 324lbft before overboosting to 350lbft.
