Volkswagen Taigun review

I bought new Taigun Highline 1 litre Mt in March 2022. No doubt, it is very comfortable. My daughter can sleep without any disturbance at 80 km speed. But, I am facing these 4 issues since first use. 1. Ac cooling - Slow start. It will take time to cool entire space. No ventilated seats in MT model. So full swept on back. 2. Gear shifting - jerking while shifting to 2nd gear. There is a low power feeling in 2nd and 3rd gear. Difficult to climb hill areas in 2nd or 3rd gear. 3. Turbo lag - slow acceleration at first 50 km (approximate). 4. 15 km/l average in highways.
