Same engine, same mileage, same six airbags: here is the one real difference between India’s rebadged MPV twins, and what it is actually worth.
The Maruti Suzuki Ertiga and Toyota Rumion share the same 1.5-litre K15C Smart Hybrid engine, the same 103 PS and 136.8 Nm, the same 26.11 km/kg ARAI-claimed CNG mileage, and six airbags standard on every single variant, because the Rumion is built on Maruti’s own production line under the two companies’ alliance. Toyota changes three things: the badge, the warranty, and the price, by ₹75,200 to ₹1.07 lakh depending on which variant you compare.
Which One Should You Actually Buy
Buy the Maruti Ertiga VXi CNG at ₹10.94 lakh unless you expect to put more than 40,000 km on the clock within two years, which is genuinely common for a 7-seater doing school runs, airport pickups and weekend highway trips. The Toyota Rumion S CNG at ₹11.69 lakh carries a 3-year/1,00,000 km standard warranty against the Ertiga’s 2-year/40,000 km, and on a CNG fuel system, that extra coverage can be worth more over time than the ₹75,200 you pay upfront.
Where the ₹75,200 to ₹1.07 Lakh Premium Actually Goes
| Variant level | Maruti Ertiga | Toyota Rumion | Rumion premium |
| Entry Petrol MT | VXi: ₹9,95,300 | S: ₹10,77,000 | ₹81,700 |
| CNG MT | VXi CNG: ₹10,93,800 | S CNG: ₹11,69,000 | ₹75,200 |
| Mid Petrol AT | ZXi AT: ₹12,36,500 | G AT: ₹13,44,000 | ₹1,07,500 |
| Top Petrol AT | ZXi+ AT: ₹13,14,100 | V AT: ₹14,21,000 | ₹1,06,900 |
What Is Actually Different Between Them
| Spec | Ertiga | Rumion |
| Engine, power, torque | 1.5L K15C, 103 PS / 136.8 Nm | Identical |
| ARAI mileage (Petrol MT / CNG) | 20.51 kmpl / 26.11 km/kg | Identical |
| Airbags | 6 standard, all variants | Identical |
| Crash-test data available | 2019 Global NCAP, 3 stars, 2-airbag test car | Same 2019 test, cited by reference |
| Standard warranty | 2 years / 40,000 km | 3 years / 1,00,000 km |
| Max extended warranty | 5 years / 1,00,000 km | 5 years / 2,20,000 km |
| Dashboard, audio | Standard trim, 4-speaker stock audio | Wood-finish dash insert, Arkamys-tuned 6-speaker system |
The Crash Test Neither Car Has Actually Had
Both cars lean on the same single data point: a 2019 Global NCAP test of the older Ertiga, which scored 3 stars for adults and 3 for children, run on a test car with just 2 airbags. Neither the current Ertiga nor the Rumion, both sold with 6 airbags standard since then, has been independently crash-tested since. Treat the 3-star figure as outdated background, not a verdict on the car you would actually drive home.
Is CNG Worth It Over Petrol on Either Car?
The CNG MT variant costs about ₹98,500 more than the equivalent petrol MT on both cars. At Delhi’s October 2026 rates, CNG runs about ₹86.98/kg against petrol at ₹102.12/litre. On the ARAI-claimed figures, that works out to roughly ₹3.33 per km on CNG versus ₹4.98 per km on petrol, a saving of about ₹1.65 per km that pays back the CNG premium in around 60,000 km, roughly four years at typical family use.
Those are claimed numbers. Owners running the Ertiga’s CNG tune on Team-BHP report closer to 22 to 24 km/kg in city traffic, which stretches the payback to nearer 70,000 km but does not erase the case for CNG if you are keeping the car past year four.
The Rumion is not a worse car for costing more. It is the same car with a longer warranty and a nicer dashboard trim, and whether that is worth ₹75,200 to ₹1.07 lakh depends entirely on how many kilometres you plan to put on it.
If you are financing either one, run the real monthly number rather than guessing: the Ertiga’s own EMI calculator and on-road price in Delhi both use current rates rather than the flat ex-showroom figures above. For the full spec-by-spec breakdown of both cars side by side, see our Ertiga vs Rumion comparison. And if a 7-seater under ₹15 lakh is the actual brief, not just these two, our full list of 7-seaters under ₹15 lakh covers the rest of the segment.
Is the Toyota Rumion just a rebadged Maruti Ertiga?
Yes. It is built on Maruti’s production line under the Toyota-Suzuki alliance and shares its engine, mileage figures, dimensions and 6-airbag safety kit with the Ertiga. Toyota’s changes are limited to badging, a mesh grille, interior trim details and the warranty terms.
Does the Rumion have a better crash-test rating than the Ertiga?
No. Both cars point back to the same 2019 Global NCAP test of an older, 2-airbag Ertiga. Neither the current 6-airbag Ertiga nor the Rumion has been independently crash-tested since, so neither car can honestly claim a rating that reflects what is actually on sale today.
Is the CNG version worth it over petrol on these cars?
At Delhi’s current fuel prices, the roughly ₹98,500 CNG premium pays for itself in around 60,000 to 70,000 km, factoring in real-world mileage reports rather than just the ARAI claim. If you plan to keep the car fewer than three to four years or drive under 15,000 km a year, petrol likely works out cheaper overall once you include the CNG kit’s resale impact.
