What is the engine power of Maruti Ignis diesel version?

Yes, you can. But do try it after warranty period.

Hoo nothing much

Ignis is better choice considering the VFM it brings. Both of them have more or less same build quality. I10 looks dated, old school design. Ignis is fun to drive, both in city and on highway as well. Remember it is based on the same platform as that of new Swift. It gets everything a swift gets and even better when it comes to customisations available. I preferred Ignis AMT Zeta as it was a complete package.

In terms of overall cost, Suzuki is any day better than Hyundai. Ignis service cost comes up to 6k annually compared to 10-11k for Grand i10. Spare parts of Ignis are far economical compared to Grand i10.

No, you wouldn't face such issues. Maruti Suzuki has built the Ignis on its fifth-gen A-platform, which is stiffer than before and further improves its on-road stability and thanks to the heaviness at the ‘wheel, the Ignis would maintain straight lines on highways with minimal steering corrections.

I mostly drive my ignis on rough road or hilly area. Its very much comfortable for off road driving also. Its comes with 180mm ground clearance.

There would not be a possibility to install hill hold assist externally. Moreover, you may connect with the nearest authorized service center for more details. Follow the link and select your desired city for service centers.
