Imagine the luxury. Pre-‘One Ford’, before the age of austerity, imagine being in a position to not only develop a hatchback just for Europe but also decide that, when you want a hot version of it, you’ll pull it away from the production line for finishing, in expensive fashion.
Thus was the 2002 Mk1 Ford Focus RS: unique bodywork, a limited-slip differential, carbonfibre added to the interior and a tasty turbocharged engine.
Someone signed off the prospect of building 4501 of them and selling them at the remarkably low price of £19,995, which seems too good to be true now. For Ford’s bottom line, it was quite bad, but it did revive the RS brand to considerable effect.
The Mk1 Focus RS wasn’t universally loved at launch, though. Some thought its uncompromising nature – and it was uncompromising – harmed it as a driver’s car.
I remember driving one on the Cat and Fiddle road at its launch and, mid-hairpin, applying more power. The Quaife limited-slip diff would hook up and pull the front wheels into the corner – a remarkably unusual thing for a front-driver. There was more torque steer than in practically anything but a front-wheel-drive racing car, and it didn’t please everyone. Not just the accountants were miffed.
It was no surprise, then, that when the Mk2 Focus RS came around in 2009, things were a bit different.
Ford wanted to make 8000 of them over two years and, crucially, make some money out of them. More than 4000 came to the UK alone, priced from at least £26,995, so it made money, despite the fact that it felt fairly well removed from the standard Focus. Mechanically, it wasn’t, though – not by as much as the first one, at least.
Sure, it had fattened arches and a limited-slip diff, but it rolled down the same production line as the regular Focus, which makes a huge difference to the production cost.
That meant Ford could afford to be a little liberal with some of the hardware, so it gave the RS RevoKnuckle suspension on the front struts, to cut the torque steer that would come with 301bhp and 325lb ft.
RevoKnuckle is a different name for a similar system that Renault and Vauxhall use and it’s worth going over it again. In a normal strut, the whole shebang pivots around the spring strut itself. Which is fine but, when you consider how much torque steer the 212bhp, 229lb ft Mk1 Focus gave you, you can imagine what the Mk2 would be like.
Without a limited-slip diff, some full-throttle energy just scrabbles away into the ground. With an LSD, though, both tyres are hunting for grip and finding it, tugging the steering this way and that while they’re doing it.
That’s where a RevoKnuckle/dual-axis strut comes in. It’s an extra knuckle, closer to the wheel’s centre line than the strut, about which the wheel pivots instead of at the strut. That reduces the radius about which the wheel rotates and, in turn, reduces the amount of force the wheel can exert on the steering.
