Before we get a little light-headed, it’s worth stating what the RS isn’t. In the field of usable, fast, indulgent hot hatchbacks, headed by the Volkswagen Golf R, it is an also-ran.
The weighty, camber-addled steering is a little too arduous at low speeds for the casual user, and its stiffened ride, while respectably compliant given the level of intent, is nevertheless too firm and percussive to be thought of as genuinely comfortable.
It is also not, perhaps more surprisingly, an entirely natural or appealing track tool, its substantial weight, power and (very clever) stability control all contributing to what we’d assume is a reasonably voracious appetite for brake components and tyres.
The space it slots into somewhere in between, however, is terrific. Road-focused, immersive, ostensibly barmy and tremendously engaging, the Focus delivers a chassis dynamic cut from the same rear-drive-biased cloth as the Nissan GT-R and Audi R8, yet it manages to be arguably more accessible and entertaining than either.
High praise indeed, but the RS earns it repeatedly, sauntering into every constant-radius turn with the transparent aim of moving progressively from being dependably front-driven to bullishly neutral to gratifyingly tail-happy.
The throttle-induced exploits of its back end are not the limit of the RS’s talent, but they are what sets it dramatically apart from the current crop of stability-biased rivals.
