With more than 400bhp, the engine does, of course, feel very strong indeed. Power delivery is very linear throughout the rev range and it pulls hard from as little as 2000rpm, with sharp throttle response.
Just like the standard motor, though, this is an effective rather than evocative power unit. It gives massive straight-line performance, but there isn’t much by way of sparkle or fizz in the delivery, while the soundtrack is all flat, droning turbo blare, albeit overlaid now with exaggerated exhaust pops and cracks on the overrun.
With more power for the four-wheel drive system to deal with, there is a little more tramlining on a wide-open throttle than before, particularly on very rutted surfaces, with the front end tugging itself across the width of the road. But in every other ride and handling measure, the Litchfield Focus RS is a very good improvement over the standard car.
The ride quality in Normal mode is better now, and in Sport, the chassis also deals with those sharp, pointed bumps in the road surface that make the standard car feel skittish at times. In Track mode, meanwhile, and with the dampers in their firmest setting, there is actually enough fluency and compliance to cope with a reasonably broken B-road. By way of comparison, the standard Focus RS actually feels too uncompromising in its stiffest mode for even very smooth race tracks.This means there's now a whole other suspension mode that you would actually consider using on the road.
Litchfield has done very well to preserve is the standard car’s remarkable balance and agility. The steering - not so much the feel of the rack or the level of feedback, but more the response of the front end - is truly staggering; the car darts into corners with the precision and immediacy of a Tarmac rally car. It makes you think you couldn’t possibly turn in to a corner too quickly.
That’s backed up by the sweetest chassis balance of any hot hatch on sale. The instant the front end is locked onto a line, the rear end yaws around fractionally so that you don’t so much slice through bends as sweep around them. In reality, the rear end is only sliding a very small amount, but it gives the impression of the Focus RS being one whole piece, rather than a front axle followed by a rear axle. It’s an additive and enormously thrilling sensation.
The Focus RS - particularly with 410bhp - is colossally fast along a twisting road. In fact, after every dash between the hedgerows, you emerge utterly convinced that nothing, no supercar or lightweight special, could possibly have kept up. You’d be wrong, of course, but it’s a mightily impressive trick.
Perhaps the car’s biggest weakness, in both standard and Litchfield specification, is the height at which the driver’s seat is set. For the first five miles, you’re certain somebody must have jacked it up to its highest possible setting, that you must be able to lower it, but, in fact, that’s just where it’s fixed. With time and familiarity, though, you get used to it.
