Maruti Suzuki Brezza Facelift Mileage Revealed: How the 1.0 Turbo, 1.5 Petrol and CNG Numbers Stack Up

Maruti Suzuki has finally pulled the covers off the Brezza facelift, and while the reworked grille and bigger 10.1-inch touchscreen will grab eyeballs, the numbers that matter most to India's value-conscious SUV buyer sit quietly on the last page of the brochure — the fuel efficiency figures. This time, there are more of them to talk about than ever before.

The headline change is a brand-new powertrain. For the first time in its life, the Brezza gets a 1.0-litre turbocharged Boosterjet petrol engine — the same three-cylinder unit that already does duty in the Fronx. Paired with a six-speed manual, it returns a certified 20.47 kmpl in the LXI and VXI trims, dropping marginally to 19.96 kmpl in the heavier, better-equipped ZXi and ZXi+ variants. There's no predecessor to measure this against — the old Brezza never offered a turbo — so it arrives as a clean addition to the range rather than a replacement.

Here's the twist, though. The turbo may be the exciting new toy, but it isn't the mileage champion. That title still belongs to the tried-and-tested 1.5-litre K15C petrol. In manual form it now returns 21.09 kmpl (LXI, VXI) and 20.81 kmpl (ZXI) — comfortably ahead of the turbo on paper. The six-speed automatic, offered on VXI, ZXI and ZXI+, is rated at 20.17 kmpl.

Line those up against the outgoing model and the improvement is clear. The pre-facelift Brezza's 1.5 manual was certified by ARAI at 19.89 kmpl and the automatic at 19.80 kmpl. The new car, then, has clawed back roughly a full kilometre per litre on the manual and about 0.4 kmpl on the automatic — modest on paper, but meaningful over a year of city commuting where every litre counts.

The CNG story follows the same upward curve. The Brezza's factory-fitted S-CNG — now running an underbody tank borrowed from the Victoris rather than eating into the boot — is certified at 26.90 km/kg. The old CNG Brezza managed 25.51 km/kg, so the facelift adds nearly 1.4 km/kg. That is the single biggest efficiency jump anywhere in the lineup, and the number that will matter most to fleet operators and high-running buyers who have daily long commutes.

So how has efficiency improved across the board? Part of it is the mild-hybrid tech Maruti carries over — idle start-stop, brake energy regeneration, and torque assist all still feature on the petrol engines. Part of it is simply refinement of the existing hardware. Either way, the direction of travel is the right one: every engine in the facelifted Brezza is now more frugal than the version it replaces, and the buyer has more choice than before.
