I drove the 1.6 diesel today and was very impressed. I have a 1.4 petrol and the noise meter app on my phone showed the diesel to be quieter at the same speed on the same road. I did not notice any great difference in performance compared to the 2.2 diesel. I though that the engine was extremely flexible and free revving. I was disappointed to see that the IMID system was still the same and it is just as difficult to switch to see the range remaining. The car has new wheels and the aerodynamic aids on the rear wings are larger, otherwise it seems to be the same car. Would be very tempted to buy one!
