We were going to buy a 1.8TFSI s tronic sportback, but found that there was a huge lag/delay between when you press the pedal and the car reacts. The delay time on the 1.8 ruins the car for us.. we actually consider it slightly dangerous, in case you need to react quickly to get out of a situation. We've since looked up reviews online that say the same thing about that engine (one reviewer said it was uncharacteristic of audi), they recommend going for the 1.4 s tronic, which doesn't have this lag. We didn't really want to go for less power, but looks like we'll have to consider it as we want petrol and this delay/lag is very odd and ruins the car completely for us. It feels like you press the accelerator pedal, the car doesn't move, then almost a second later, it kicks in. Has anyone driven both the 1.8 (180) s tronic and 1.4 (140) s tronic and can you tell us whether the 1.4 reacts faster?
