Which vehicle should I buy?Will the one I own run on E20?
Two questions. One engine underneath both.

The problem

Five powertrains. One right answer. No way to tell.

A spec sheet is true but useless. A review is readable but not about you.

Which ray wins turns on your state's road tax, your electricity tariff, the pumps on your route, and what a battery costs in year eight.

Verdict scoped to your variant and year, with the material risks named and every piece of guidance traced to its source.

How it works

The engine decides. The model only speaks.

No live web search at conversation time — so a result is reproducible, and can be argued with.

The deterministic result renders first and stands on its own. The narration streams over it, and is checked against the payload it was given.

What you can check

Every number shows its working.

A recommendation you cannot interrogate is a guess with a decimal point on it.

Calculations run on real-world efficiency, never on claimed figures. Where there is no data, the verdict is unknown and the interface says so.

Who it is for

Four people. Four different questions.

  • First-car buyer

    A shortlist that survives year four.

  • Upgrade buyer

    Whether the switch pays back, and when.

  • Fleet or commercial

    ₹/km, payback month, ROI.

  • Petrol owner

    A straight E20 answer.
