Mahindra XUV 3XO REVX: Petrol AT or Diesel AMT Buyer Guide
For an automatic Mahindra XUV 3XO REVX shortlist, identify the fuel type and grade together. The practical task is to compare the complete specification, driving experience and ownership budget for each available combination. Mahindra's confirmed REVX update provides a useful starting point for that decision.

What Mahindra's confirmed REVX update introduced
Mahindra's 18 September 2026 announcement introduced REVX EDGE and EDGE (O), alongside a petrol automatic option for REVX M(O). It identifies the EDGE range's petrol engine as the 1.2-litre mStallion TCMPFi and the diesel as the 1.5-litre turbo-diesel CRDe.
The table below summarises the automatic options in that official variant map. It is a guide to the confirmed update; ask the dealer to verify the current orderable specification.
| REVX grade | Petrol AT | Diesel AMT |
|---|---|---|
| M(O) | Listed | Not listed |
| EDGE | Listed | Not listed |
| EDGE (O) | Listed | Listed |
Compare the complete car when changing fuel type
AutoCred analysis: a petrol-versus-diesel comparison is most useful when you identify any accompanying grade change. Otherwise, the extra amount on a quotation may include equipment as well as the powertrain, making it difficult to judge what you are paying for.
Start by comparing equivalent grades where possible. If the diesel automatic you want sits higher in the range than your preferred petrol automatic, list the additional equipment separately. Decide whether you would have chosen those features even without changing fuel type.
For context, Mahindra's release lists a panoramic sunroof, electrically folding mirrors, keyless entry and push-button start among the EDGE (O) additions to EDGE.
Test the petrol AT and diesel AMT on your normal kind of route
Arrange a test drive of the exact powertrain you are considering. A demonstration in a different engine or transmission combination cannot settle whether the proposed car suits your driving preferences.
Include moving away gently, crawling traffic, parking manoeuvres and a safe acceleration onto a clearer road. Evaluate how the car responds to small accelerator inputs and whether its gear changes feel comfortable to you. If family members will use the car, include their feedback on access, seating and ride comfort.
Ask the demonstrator to explain the selector, any manual-selection function and the procedure for starting, stopping and parking. Follow the vehicle's instructions during the drive. Choose the combination you are comfortable operating in everyday conditions.
Build an ownership comparison from your own usage
Estimate annual fuel spending using the same method for both options: planned annual distance divided by a realistic fuel-economy estimate, multiplied by the local fuel price. Treat the result as a planning estimate and check how it changes with more or fewer kilometres.
Add the complete purchase cost and obtain the applicable service schedule, warranty terms and insurance quotations. For a diesel shortlist, ask the dealer to explain the model's emissions-system operating guidance for your typical trip pattern. Avoid deciding from the fuel bill alone.
Finally, request itemised on-road quotations that identify the engine, transmission and grade. Separate optional accessories from the vehicle price, and confirm availability, delivery estimates and cancellation terms in writing.
Plan the finance before committing to a grade. Check your indicative eligible amount and estimated EMI with AutoCred before shortlisting or visiting a dealer. Results are indicative; final eligibility, rate, tenure and approval depend on the lender. Compare the estimate with the final quotation and the lender's written offer.
