Audi has released some details on its all-new Audi S1 and S1 Sportback models, the flagship cars in the A1 model line-up. Getting straight to the all-important facts, the S1 will be powered by a 2.0-litre TFSI petrol engine that produces 231hp and 370Nm of torque. Power will be feed to all four wheels through Audi’s quattro permanent all-wheel drive system. The A1’s suspension has been extensively revamped, along with the electromechanical power steering. Prices for the Audi S1 and S1 Sportback will be announced towards the end of February. We will be travelling to Sweden in March to test drive the new Audi S1 and will bring you a full report on how it drives.
