The two cars you have shortlisted fall in different segments; in fact, where the Maruti XL6 price ends, is where the Hyundai Alcazar price begins. The Alcazar is a superior vehicle in terms of comfort, quality, features and engines.
However, the XL6 MPV body style means that space efficiency on the interior is better. The XL6 has just a single engine option - a 1.5-litre naturally aspirated petrol with a 5-speed manual or 6-speed automatic gearbox.
Also, it is not as powerful as the Alcazar, but it will be more fuel-efficient. If you are budget-conscious and want to keep running costs low, the Maruti XL6 is the better choice for you. You could also consider the Kia Carens Clavis, which falls between these two on price.
