Hyundai Exter CNG: In the evolving landscape of Indian automotive choices, where fuel efficiency increasingly drives purchasing decisions, Hyundai’s introduction of the Exter CNG represents a thoughtful expansion of eco-friendly options in the compact SUV segment.
This factory-fitted CNG variant brings the benefits of dual-fuel economy to a vehicle already garnering attention for its distinctive design and feature-rich package.
But beyond the obvious economic advantages, does the Exter CNG maintain the character that makes its conventional counterpart appealing? This exploration examines how this alternative fuel variant balances efficiency with the expectations of modern urban drivers.
Hyundai Exter CNG: Design Integrity: Maintaining Character Despite Practical Additions
The transition to CNG often forces compromises in vehicle design, with aftermarket conversions typically resulting in awkward protrusions or significant reduction in luggage space.
Hyundai’s approach with the Exter CNG, however, demonstrates the benefits of factory integration, preserving much of the visual appeal and practicality that defines the standard model.
Externally, the Exter CNG remains virtually indistinguishable from its petrol-only counterpart, maintaining the distinctive silhouette that has helped position it as a stylish urban runabout with crossover aspirations.
The familiar elements remain intact: the parametric front grille flanked by split LED daytime running lights, the squared wheel arches that lend a sense of ruggedness, and the H-pattern tail lamps that create a recognizable rear signature.
The only subtle exterior indications of its dual-fuel nature are the discreet CNG badging and the additional filler cap for the gas input.
Ground clearance—a critical consideration in Indian driving conditions—remains largely unaffected despite the addition of underbody CNG cylinders, a testament to the thoughtful engineering that went into adapting the platform for this alternative fuel.
The 16-inch alloy wheels on higher trims maintain the vehicle’s proportional harmony, though entry-level CNG variants make do with 15-inch steel wheels with covers, a minor cosmetic compromise that reflects the economy-focused nature of these versions.
Color options remain consistent with the standard Exter lineup, offering buyers the same opportunity for personalization without being limited to a restricted palette often associated with more utilitarian variants.
This parity in visual options underscores Hyundai’s understanding that choosing CNG needn’t mean sacrificing the emotional aspects of car ownership.
Cabin Experience: Practical Adaptations to Dual-Fuel Living
Inside, the Exter CNG largely preserves the appealing cabin environment of the standard model, with thoughtful adaptations to accommodate its dual-fuel nature.
The dashboard maintains its clean, horizontally oriented design with the 8-inch touchscreen infotainment system positioned prominently at the center. Material quality remains consistent, with a mix of hard-wearing plastics and strategic soft-touch surfaces at key contact points creating an impression of durability without austerity.
The most obvious adaptation appears in the instrument cluster, which now incorporates a fuel gauge for CNG alongside the conventional petrol indicator.
The multi-information display provides additional data specific to CNG operation, including current fuel mode, estimated range, and average efficiency metrics that help drivers maximize the economic benefits of dual-fuel operation.
Seating comfort remains unchanged, with the Exter’s well-contoured front seats providing good support for urban journeys.
Rear accommodations continue to offer reasonable space for this segment, with adequate headroom thanks to the tall roof design and sufficient legroom for average-sized adults. The upholstery materials show practical consideration, balancing appearance with the durability needed in a vehicle likely to see regular family use.
The most significant practical compromise appears in luggage capacity. The factory-fitted CNG cylinder occupies a portion of the boot space, reducing cargo volume from the standard model’s 391 liters to approximately 208 liters in the CNG variant.
While this reduction is substantial in percentage terms, the remaining space remains usable for everyday urban needs such as grocery shopping or weekend bags. For families requiring occasional larger cargo capacity, the 60:40 split rear seats still allow for flexible configuration, though not with the same overall volume as the petrol-only model.
Storage solutions within the cabin remain practical, with adequately sized door pockets, a reasonably spacious glove compartment, and clever cubbies for personal items.
Cup holders are positioned for convenient access, while the center console includes a dedicated space for smartphones, reflecting contemporary usage patterns.
Technical Integration: Engineering for Dual-Fuel Efficiency
Powering the Exter CNG is Hyundai’s familiar 1.2-liter Kappa petrol engine, modified for bi-fuel operation. This four-cylinder unit produces approximately 68 horsepower and 95.2 Nm of torque when running on CNG—figures that represent a moderate reduction from the 82 horsepower and 113.8 Nm available in petrol mode.
This power differential reflects the inherent characteristics of CNG combustion rather than any engineering shortcomings.
The engine comes paired exclusively with a 5-speed manual transmission in the CNG variant, a pragmatic choice that maximizes efficiency while simplifying the powertrain.
The absence of an automatic option might disappoint some urban drivers, but this focus on the manual gearbox aligns with the efficiency-conscious nature of CNG buyers who often prioritize running costs over convenience features.
The factory-fitted CNG kit incorporates numerous safety features, including thermal and pressure sensors, automatic cylinder shut-off, and independent electronic control unit for gas delivery.
The steel CNG cylinder has a capacity of approximately 60 liters (water equivalent), providing a usable gas capacity that offers a range of roughly 250-280 kilometers under typical driving conditions.
Combined with the unaffected 37-liter petrol tank, this dual-fuel arrangement provides a theoretical combined range exceeding 650 kilometers—a significant advantage for those concerned about CNG station availability during longer journeys.
Perhaps most impressively, Hyundai has maintained most standard safety features in the CNG variant, including dual airbags, ABS with EBD, and electronic stability control on higher trims.
This comprehensive safety package addresses potential concerns about compromises in protection systems that sometimes accompany alternative fuel variants.
Driving Experience: Balancing Economy with Engagement
Behind the wheel, the Exter CNG presents a driving experience that largely preserves the character of its petrol counterpart, albeit with subtle differences that reflect its dual-fuel nature.
Initial acceleration in CNG mode exhibits the slight hesitation typical of gas-powered vehicles, with power delivery becoming more linear once underway.
The reduced peak output is most noticeable during overtaking maneuvers or on steep inclines, where downshifting may be required more frequently than in the petrol variant.
Urban drivability remains a strength, with the light steering and compact dimensions making city navigation straightforward.
The suspension tuning strikes a reasonable balance between absorbing road imperfections and maintaining composure through corners, though the additional weight of the CNG system (approximately 100-120 kg) is occasionally perceptible in the vehicle’s responses to directional changes.
Notably, Hyundai has calibrated the CNG system to start the vehicle on petrol before automatically switching to gas once operating temperature is reached—a design choice that improves cold-start reliability and reduces wear on critical components.
The transition between fuel types occurs almost imperceptibly, with only a small indicator light in the instrument cluster signaling the change.
Drivers can also manually switch between fuels via a conveniently positioned button, allowing for on-the-fly adjustment based on performance needs or fuel availability.
NVH (noise, vibration, harshness) levels show slight increases over the standard petrol model, particularly at higher engine speeds in CNG mode.
However, these differences remain within acceptable limits for the segment and likely won’t detract from overall comfort during everyday driving.
Wind and road noise suppression continues to reflect Hyundai’s generally good insulation standards, maintaining cabin serenity at highway speeds.
Economic Proposition: The Numbers That Matter
For many potential buyers, the Exter CNG’s appeal ultimately rests on its economic advantages, and here the numbers make a compelling case for consideration.
Fuel efficiency in CNG mode typically ranges between 24-26 km/kg under mixed driving conditions, representing a significant operating cost advantage over the petrol variant’s 19-21 km/liter.
With CNG pricing holding at approximately 40-50% of petrol costs across many Indian markets, this efficiency translates to per-kilometer running costs roughly half those of equivalent petrol vehicles.
For high-mileage users such as daily commuters or ride-share operators, these savings can offset the CNG variant’s price premium (typically Rs. 90,000-1,00,000 over equivalent petrol models) within two to three years of typical usage.
Maintenance costs show minimal differences from the standard model, with service intervals remaining consistent.
The CNG system requires periodic inspection and cylinder recertification (every five years as per regulations), but these represent relatively minor additions to the overall maintenance schedule.
Hyundai’s decision to provide the same warranty coverage for CNG variants as petrol models (3 years/100,000 km standard, extendable to 5 years) demonstrates confidence in the system’s durability and should alleviate potential concerns about long-term reliability.
Insurance premiums typically run 5-7% higher for the CNG variant, reflecting the additional components and slightly higher replacement costs.
However, this marginal increase represents a negligible factor in the overall ownership cost equation when weighed against the substantial fuel savings.
Perhaps the most frequently overlooked economic factor is the improved residual value that factory-fitted CNG models command compared to aftermarket conversions.
The Exter CNG’s integration of the system from the production stage, complete with manufacturer warranty and certified safety compliance, typically results in stronger resale values and broader market appeal when the time comes to upgrade.
Variant Strategy: Choices Across the Spectrum
Hyundai’s approach to the Exter CNG variant lineup demonstrates understanding of the diverse needs within the efficiency-focused segment.
Rather than limiting the CNG option to bare-bones base variants—a common industry practice—the company offers the dual-fuel system across multiple trim levels, from the value-oriented S to the well-equipped SX(O).
This strategy acknowledges that choosing CNG doesn’t necessarily indicate willingness to compromise on features or comfort.
The base S variant provides essential amenities including power windows, central locking, and a digital instrument cluster, while mid-range SX adds the 8-inch touchscreen with smartphone connectivity, rear-view camera, and automatic climate control.
For those unwilling to compromise on premium features, the range-topping SX(O) CNG variant retains most of the highlights that make its petrol counterpart appealing, including LED headlamps, cruise control, wireless phone charging, and connected car technology.
This democratization of features across fuel types represents a progressive approach that respects consumer preferences while still acknowledging the practical focus of CNG buyers.
