From your shortlist, we would rule out the Renault Triber. The MPV is genuinely spacious inside, even in the third row; however, the engine is down on performance.
Given that most of your driving is on the highway, you would be better off with the Maruti Suzuki Fronx or the Maruti Suzuki Brezza.
Both cars are good options, but between the two, if rear seat space is important, we would recommend the Brezza, while the Fronx is the better one to drive.
