That power feeds through a six-speed manual gearbox - no highfalutin flappy-paddle affair here - to a bespoke all-wheel drive system capable of continuously varying the torque balance both front-to-back (with a maximum 70 per cent reaching the rear), and across the rear axle. Rather than using a traditional limited slip differential or e-diff, the Focus apparently employs a unique mechanical solution.
"We’re using an all-wheel drive system we believe no one else is," says Ford Performance director Dave Pericak. "The RDU has a clutch at the front and twin clutches at the back, one on either side of the diff. So we can control the torque front-to-back but also side-to-side. We push the car around the corner, we don't slow the car down.
"It’s an all-new AWD system designed specifically for the RS. The capability is unbelievable. It’ll shock you when you get behind the wheel. We didn't want to do a warmed-over version of the last RS. We wanted a new level."
