The RPM of this car is too high even in not running condition. facing problem of suddenly too much speed in after changing to second gear with RPM 2000-2100 without pressing accelerator. its totally abnormal. even dealer is not able to solve this problem. company is also not able to find out. 27 to 29 kmpl(petrol) on highway A great comeback by Tata Motors. Now all depends on Tata Management how they maintain connectivity in reality with car owners and resolve thier issues in 7 days, technical within 24-48hrs. Tata should not leave anything on dealers as they are operating only to earn money. .i feel the performance specs are more than enough for city conditions .we really dont need anything more powerful than that.i bought it solely for mileage purposes.and comfy long drives.ive put 1000 bucks and still there 130 kms left
