Design remains unchanged compared to standard Wagon R; Unique badge and side decals add to distinction
Runs on petrol blended with up to 85 percent ethanol (E85).
The 1.2-litre engine has been reworked for more power and torque.
The feature list continued with tech like 7-inch touchscreen infotainment, wired Android Auto/Apple CarPlay, Manual AC, day/night IRVM.
Six airbags are standard, with an electronic stability program (ESP).
India's first genuinely mass-market E85-compatible car? The Maruti Wagon R Flex Fuel. The changes underneath are engineering work, not cosmetic, and they let the car run on higher ethanol blends in petrol.
Maruti pairs this flex-fuel engine with a 5-speed manual only. Outside, nothing changes. The familiar tall-boy stance carries over, along with the 14-inch alloys, the blacked-out C-pillar for that floating-roof look, and the large vertical taillamps. Here are more details you should know about it:
The Wagon R Flex Fuel runs a fully reworked 1.2-litre petrol engine. Maruti has re-engineered it to cope with the corrosive nature of high-ethanol blends and tuned it for performance. Power and torque both improve over the standard E20-compliant unit, the company says. Exact figures? Not disclosed.

E85 should typically cost less than standard petrol, so that figure will set the real-world running-cost gap.
The flex fuel variant keeps the ZXI feature set intact. A 7-inch touchscreen runs wired Android Auto and Apple CarPlay, paired with a 4-speaker audio setup. Inside, the dashboard is dual-tone beige and black. The steering wheel tilts, all four windows are powered, and the ORVMs adjust and fold electrically.
Six airbags come as standard. ESP, ABS with EBD, hill hold assist, rear parking sensors and speed-sensitive auto door locks round out the active-safety kit. A full pack for the segment.
E85 fuel availability is the catch. India's high-blend ethanol pump network is still early-stage, with stations clustered in a handful of regions. Buyers should check whether E85 is sold in their city or along their regular routes before counting on the flex-fuel capability.

The Wagon R Flex Fuel slots into a wider alternative-fuels push. Two-wheelers are on the same track, with launches like the E85-compliant Hero commuter bikes. A bigger pump network makes flex-fuel ownership more workable day to day.
Maruti is targeting early adopters with the Wagon R Flex Fuel, plus buyers in regions where E85 is rolling out. The pitch? Lower running costs from cheaper ethanol-blended petrol, and a greener footprint. The higher power and torque numbers give a performance edge over the standard car.

Rivals include its own siblings, the Maruti Celerio and Maruti Swift, plus the Tata Tiago and Hyundai Grand i10 Nios. None of them runs E85 flex fuel, which leaves the Wagon R on its own in the affordable hatch segment.
