RS1 prototype spied testing in and around the ring wearing a large rear roof spoiler and very little camouflage.
These are the very first spy shots of the 2012/2013 Audi RS1 spied testing on and around the Nürburgring test circuit.
Set to be the range-topper of the Audi A1 family, the RS1 is spied wearing a large rear roof wing/spoiler and very little camouflage.
But what the prototype is sporting under the hood is the big question.
Earlier this year, we spied an S1 testing on the ring and that model is expected to come with a turbocharged 1.6-liter unit that produces 220 PS (162 kW / 217 hp) paired to a new quattro all-wheel drive system.
So we expect substantially more output than that on the RS1 with, of course, quattro all-wheel drive. This Audi A1 Clubsport quattro Concept which was shown at the Wörthersee Tour 2011 was powered by a highly-modified 2.5 liter, five-cylinder TFSI unit with an output of 503 PS (370 kW / 496 bhp) and 660 Nm (486.79 lb-ft) of torque.
That proves that Audi can fit the 2.5 liter TFSI unit into the A1's engine bay with a quattro system and a six-speed manual gearbox too. But output will likely be dialed to much less than the 340 PS (250 kW / 335 hp) and 450 Nm (332 lb ft) of torque of the 2.5 TFSI unit on the Audi TT-RS and RS3 models.
The Audi RS1 will launch in 2012.
