The Maruti Suzuki Fronx’s ₹9.76 lakh Zeta Turbo Petrol MT is the variant to buy. It is the cheapest way into the 100 PS turbo engine, and it is also the first trim to add side airbags, a reversing camera and Suzuki Connect. On The Spec’d’s own on-road figures, that same car costs ₹11.26 lakh in Mumbai, with an EMI of about ₹18,924 a month on a 20% down payment. The Alpha Turbo AT above it costs ₹2.13 lakh more for a head-up display and a 360-degree camera most owners will use twice. Before you book either one, know what the Fronx skips at every price: ADAS, TPMS, and a crash-test score that is not reassuring.
The Fronx Variant Ladder: What Each Step Actually Buys
Maruti sells the Fronx across 12 variants and three engines: a 90 PS naturally aspirated 1.2-litre petrol, a factory-fitted CNG option on the same block, and the 100 PS 1.0-litre Boosterjet turbo with a mild smart-hybrid assist. Here is what each step over the one below it actually adds, ex-showroom.
| Variant | Ex-Showroom | Step Over Previous | What It Adds |
| Sigma Petrol MT | ₹6.90 Lakh | – | Base trim |
| Delta Petrol MT | ₹7.75 Lakh | +₹85,000 | 7-inch touchscreen, wireless Android Auto/CarPlay, electric folding mirrors, 4 speakers |
| Sigma CNG MT | ₹7.94 Lakh | +₹1.04 Lakh over Sigma Petrol | Factory S-CNG kit, 55-litre cylinder |
| Delta+ Petrol MT | ₹8.15 Lakh | +₹39,600 | LED headlamps and DRLs, auto headlamps, painted alloys |
| Delta+ Turbo Petrol MT | ₹8.97 Lakh | +₹82,400 over Delta+ Petrol | 1.0L Turbo Boosterjet, 100 PS/147.6 Nm |
| Zeta Turbo Petrol MT | ₹9.76 Lakh | +₹79,000 | Rear camera, wireless charger, push-button start, rear AC vents, Suzuki Connect. Best value. |
| Alpha Turbo Petrol MT | ₹10.61 Lakh | +₹85,000 | Head-up display, 360-degree camera, 9-inch touchscreen, cruise control, leather-wrapped wheel |
| Zeta Turbo Petrol AT | ₹11.04 Lakh | +₹1.28 Lakh over Zeta MT | 6-speed torque-converter automatic with paddle shifters |
| Alpha Turbo Petrol AT | ₹11.89 Lakh | +₹85,000 | Same automatic, top-trim kit carried over |
The jump from Zeta to Alpha buys a head-up display, a 360-degree camera, cruise control and a leather-wrapped wheel, none of which change how the car drives or how safe it is. The side airbags, camera and Suzuki Connect that matter are already standard from the Zeta. Want the automatic without paying for Alpha’s extras? The Zeta AT at ₹11.04 lakh is the more sensible ₹1.28 lakh to spend.
Claimed vs Real: Mileage, Crash Safety and the ADAS Gap
| What the Brochure Says | What The Spec’d Found |
| Turbo MT claimed: 21.50 kmpl | Spinny’s real-world mileage tracking puts the Fronx turbo-petrol nearer 17 km/l in everyday use, roughly a 21% drop from the claimed figure. |
| Crash safety: not independently rated in India-spec form | The Fronx sold in Australia scored just 1 star in ANCAP’s 2025 testing. Bharat NCAP has not yet published a rating for the India-spec car. |
| Driver assistance | No ADAS and no TPMS on any variant, including the range-topping Alpha AT. |
None of this means the Fronx is unsafe, but buyers cross-shopping a Tata Punch or Nexon, both of which offer ADAS on mid-to-top trims, should know the Fronx does not compete there at any price. The ANCAP score is for the Australian-spec car, not an India test, but with no India-spec result published, treat it as the best public data point available.
Turbo, CNG or Plain Petrol: Which One Actually Pays Off
The naturally aspirated petrol costs ₹4,690 to run per 1,000 km at its claimed 21.79 kmpl; the turbo costs only ₹60 more at ₹4,750, worked out at Delhi pump prices on 2 November 2026. That is a trivial penalty for 10 more PS, so the turbo is an easy yes if you can afford the ₹82,400 step up to Delta+ Turbo.
CNG is worth doing the math on. Sigma CNG MT costs ₹1.04 lakh more than Sigma Petrol MT, but running cost drops to ₹3,050 per 1,000 km against petrol’s ₹4,690, a saving of ₹1,640 per 1,000 km. That pays back the CNG premium in about 63,400 km, around four years for a commuter covering 1,200 km a month. Drive less than that and petrol is cheaper overall; drive more and CNG wins clearly.
What the Fronx Costs on the Road in Mumbai
The base Sigma Petrol MT comes to about ₹8.05 lakh on the road in Mumbai on The Spec’d’s city price page, against ₹7.56 lakh in Puducherry, the cheapest of the 39 cities the site prices, a ₹49,004 gap driven mostly by Maharashtra’s 11% road tax. The recommended Zeta Turbo MT works out to ₹11.26 lakh on the road in Mumbai, ex-showroom ₹9.76 lakh plus tax, insurance and FASTag, with an EMI of about ₹18,924 a month on 20% down over five years at 9.5% interest. These are The Spec’d’s estimates; confirm the final figure with your dealer before booking.
Fronx vs Baleno: Same Platform, Different Body
The Fronx shares its platform and engines with the Maruti Baleno, which starts at ₹7.01 lakh on the road in Mumbai against the Fronx’s ₹8.05 lakh, roughly a ₹1 lakh premium for crossover styling and a higher seating position. See the full Baleno vs Fronx comparison. Skip the SUV look and the Baleno gets you most of the same car for less.
Who Should Buy the Maruti Fronx
Buy the Zeta Turbo Petrol MT if you want a genuinely quick, well-equipped compact SUV and are willing to live without ADAS. Buy the Sigma or Delta CNG if running cost matters more than performance and you drive enough to clear the payback distance. Skip the Alpha AT unless the head-up display and 360-degree camera are must-haves, and skip the whole car if ADAS is non-negotiable for your family. Browse every compact SUV on sale in India to see how the Fronx’s price and kit stack up against the rest of the segment.
Does the Maruti Fronx have ADAS?
No. No Fronx variant, including the top-spec Alpha Turbo AT, offers ADAS or a tyre pressure monitoring system. Rivals like the Tata Nexon and Tata Punch offer ADAS on their higher trims.
Is the Fronx turbo-petrol worth it over the 1.2-litre petrol?
Largely yes. The turbo’s claimed mileage of 21.50 kmpl is barely behind the naturally aspirated engine’s 21.79 kmpl, so you get meaningfully more power for a running-cost difference of about ₹60 per 1,000 km.
How much does the Maruti Fronx cost on the road in Mumbai?
The base Sigma Petrol MT comes to about ₹8.05 lakh on the road in Mumbai, and the recommended Zeta Turbo Petrol MT comes to about ₹11.26 lakh, both on The Spec’d’s city price estimates including road tax, insurance and FASTag.
