Renault Triber gets a pretty decent AC performance. You also get air-con vents mounted on the B-pillar(dedicated AC vents for each passenger) with a secondary compressor that can function independently and further enhance the Triber experience. Do take a test ride in order to get better clarity. Check out authorised dealership details.
