At first glance, there’s not a great deal to mark out the S1 from regular Audi A1 hatches. But if you get the chance to put the two side by side and take a closer look, it’s easier to spot.
Then you can tell that the S1 rides 25mm lower than standard Audi A1s, and although there are no changes – unsurprisingly – to the metalwork, the front bumper is deeper and the front grille allows more air into the engine bay. The sills are deeper and there are aerodynamic addenda (or an impression of them) at the rear.
The engine is the Volkswagen Group’s ubiquitous 2.0-litre ‘EA888’ engine, as you’ll also find in everything from an Audi TT to a Volkswagen Golf R. As always, there is the mention of unique tuning – true to an extent, because the exhaust and induction routing of no two models is quite the same.
But the reality is that there are few changes to this widely used engine that, here, develops 228bhp and 273lb ft of torque, which plateaus from as little as 1600rpm. The RS1 scheduled to make its debut in 2017, will produce 280bhp from the same 2.0-litre 'EA888' engine.
It drives through a six-speed manual gearbox only. In most EA888 applications, there’s at least the option of a dual-clutch automatic, but there’s something determinedly old-school and likeable about the lack of such a choice here, and it drives through a four-wheel drive system, which is where the S1 gets interesting.
