Is the Hyundai i30 Good on Fuel?
The Hyundai i30 offers competitive fuel economy for a compact hatchback or sedan, especially when compared with older naturally aspirated petrol vehicles.
Modern i30 models benefit from technologies designed to reduce fuel consumption, including efficient engine management, turbocharging, automatic transmissions, and mild-hybrid assistance on selected versions.
However, not every Hyundai i30 is equally economical.
A standard petrol model designed for everyday commuting generally consumes less fuel than the performance-focused i30 N.
Similarly, the i30 Sedan Hybrid can achieve significantly lower consumption than a conventional petrol-only version.
Hyundai i30 Fuel Consumption at a Glance
The following table shows selected official combined fuel consumption figures for Australian-market models.
| Hyundai i30 Version | Engine | Fuel Consumption |
|---|---|---|
| i30 N Line Hatch (MY25) | 1.5L turbo mild hybrid | 5.6 L/100km |
| i30 Sedan | 2.0L petrol | 6.1 L/100km |
| i30 Sedan N Line (MY25) | 1.6L turbo petrol | 6.6 L/100km |
| i30 Sedan Hybrid | 1.6L petrol hybrid | 3.9 L/100km |
| i30 N Hatch (MY25) | 2.0L turbo petrol | 8.5 L/100km |
| Earlier i30 Hatch | 2.0L petrol | 7.3–7.4 L/100km |
| Earlier i30 N Line Hatch | 1.6L turbo petrol | 7.1–7.5 L/100km |
These figures are based on published Australian laboratory fuel-consumption ratings for the relevant model generations. They shouldn't be interpreted as guaranteed real-world results.
The most important takeaway is that the engine and model year make a substantial difference.
Hyundai i30 Hatch Fuel Consumption
The Hyundai i30 Hatch has long been a popular choice for drivers who want a compact, practical vehicle without excessively high running costs.
Its fuel efficiency depends largely on whether we're looking at an older naturally aspirated engine or a newer turbocharged mild-hybrid version.
Hyundai i30 1.5 Turbo Mild-Hybrid
The updated Australian-market i30 N Line Hatch introduced a 1.5-litre turbocharged petrol engine combined with a 48-volt mild-hybrid system.
This engine produces approximately 117 kW and delivers a useful combination of everyday performance and fuel efficiency.
Its official combined consumption is approximately 5.6 L/100km.
That means the vehicle theoretically uses 5.6 litres of petrol to travel 100 kilometres under the official combined testing cycle.
For a petrol-powered hatchback with reasonably strong performance, this is a good result.
The mild-hybrid technology helps the car recover energy and reduce unnecessary engine operation under suitable driving conditions.
However, the system does not turn the i30 into a fully electric vehicle, and it cannot provide the same electric-only driving capabilities as a full hybrid.
Hyundai i30 2.0 Petrol Fuel Consumption
Older Australian Hyundai i30 Hatch models were commonly available with a naturally aspirated 2.0-litre petrol engine.
Depending on the transmission, official combined consumption was approximately:
- Manual transmission: 7.3 L/100km.
- Automatic transmission: 7.4 L/100km.
These figures are higher than those of the newer mild-hybrid models.
Nevertheless, the 2.0-litre petrol engine offers a straightforward driving experience and sufficient performance for everyday commuting.
If we primarily drive on highways, achieving reasonable fuel consumption is possible.
Heavy urban traffic, however, can increase consumption considerably.
Hyundai i30 1.6 Turbo Fuel Economy
Earlier N Line models equipped with a 1.6-litre turbocharged petrol engine generally recorded official combined consumption between 7.1 and 7.5 L/100km, depending on the transmission.
This engine provided stronger acceleration than the standard petrol alternatives, although that additional performance came with greater fuel consumption.
For drivers who enjoy responsive acceleration but still need a practical daily vehicle, it represented a compromise between efficiency and performance.
Hyundai i30 Sedan Fuel Consumption
The Hyundai i30 Sedan offers a different driving experience from the hatchback.
It provides a more traditional four-door body style, a spacious interior, and multiple engine options in Australia.
Despite being a sedan, it can deliver competitive fuel efficiency.
Hyundai i30 Sedan 2.0 Petrol
The i30 Sedan equipped with the SmartStream 2.0-litre petrol engine has an official combined fuel consumption figure of approximately 6.1 L/100km.
Its published Australian figures include:
| Driving Condition | Fuel Consumption |
|---|---|
| Urban | 8.5 L/100km |
| Extra-urban | 4.7 L/100km |
| Combined | 6.1 L/100km |
These figures demonstrate how much driving conditions can influence fuel consumption.
On open roads, the engine can operate efficiently at relatively constant speeds.
In congested traffic, repeated acceleration, braking, and idling increase the amount of petrol required.
Hyundai i30 Sedan N Line
The i30 Sedan N Line combines sportier styling with a more powerful turbocharged petrol engine.
The Australian MY25 1.6-litre turbo model has a published combined fuel consumption figure of approximately 6.6 L/100km.
This is slightly higher than the regular 2.0-litre Sedan.
However, the N Line offers stronger acceleration and a sportier character.
For drivers who want enjoyable performance without the running costs associated with a high-performance sports car, it may be a reasonable option.
Is the Hyundai i30 Hybrid Fuel Efficient?
The Hyundai i30 Sedan Hybrid is one of the most economical versions available within the Australian i30 family.
Its 1.6-litre petrol-electric hybrid powertrain achieves an official combined fuel consumption figure of approximately 3.9 L/100km.
That's considerably lower than the regular petrol-powered Sedan.
How Does the Hybrid Save Fuel?
Unlike a conventional petrol vehicle, the i30 Sedan Hybrid combines an internal combustion engine with an electric motor and battery.
The system can reduce petrol consumption by using electric assistance and recovering energy during deceleration.
Depending on operating conditions, the electric motor can also provide propulsion without the petrol engine running continuously.
This technology is especially beneficial in urban traffic, where frequent stopping and starting would normally increase fuel consumption.
Is the Hyundai i30 Hybrid Worth It?
For drivers covering significant annual distances, particularly in cities, the hybrid can offer substantial fuel savings.
However, we should also consider the purchase price.
If the hybrid version costs noticeably more than the equivalent petrol model, the financial benefit depends on how much we drive and the difference in fuel consumption.
A driver covering 25,000 kilometres annually is more likely to recover the additional purchase cost through fuel savings than someone travelling only 5,000 kilometres per year.
We should therefore calculate the potential savings before deciding.
Hyundai i30 N Fuel Consumption
The Hyundai i30 N is a different proposition from the regular i30.
Designed primarily for driving enthusiasts, it features a powerful 2.0-litre turbocharged petrol engine and performance-oriented engineering.
This content may interest you!
Subaru Liberty Fuel Consumption: Complete GuideThe Australian MY25 i30 N Hatch has an official combined consumption figure of approximately 8.5 L/100km.
That is substantially higher than the regular i30 Hatch.
Why Does the Hyundai i30 N Use More Fuel?
Several factors contribute to its higher fuel consumption.
- A more powerful turbocharged engine.
- Performance-oriented engine calibration.
- Wider tyres and additional mechanical grip.
- Aggressive acceleration during sporty driving.
- Higher energy requirements when driving enthusiastically.
During relaxed highway driving, fuel consumption may be relatively reasonable for a performance car.
However, frequent hard acceleration and demanding driving conditions can push consumption well above the official combined figure.
If fuel economy is our main priority, the regular i30 or hybrid is a more suitable choice.
How Fuel Efficient Is the Hyundai i30 in Real Life?
Official fuel economy figures are useful for comparing vehicles, but actual driving conditions rarely match laboratory tests exactly.
In everyday driving, we may experience different results depending on traffic, terrain, vehicle maintenance, and driving habits.
For example, independent Australian road tests of the updated 1.5-litre mild-hybrid i30 Hatch have recorded overall consumption around 7.2–7.3 L/100km during mixed driving.
That is noticeably higher than its official 5.6 L/100km rating.
However, those results reflect particular test routes and driving styles rather than a universal real-world average.
Factors That Affect Real-World Consumption
The most significant factors include:
- Traffic congestion: Frequent stopping and starting increases petrol consumption.
- Driving style: Rapid acceleration requires more fuel.
- Road conditions: Steep hills increase engine workload.
- Vehicle weight: Additional passengers and luggage require more energy.
- Air conditioning: Climate control increases energy demand.
- Tyre pressure: Underinflated tyres increase rolling resistance.
- Vehicle maintenance: Mechanical problems can reduce efficiency.
Two drivers using identical Hyundai i30 models may therefore record considerably different fuel economy figures.
Is the Hyundai i30 Fuel Efficient in City Driving?
The Hyundai i30 can be reasonably economical in urban environments, but the powertrain matters.
For conventional petrol models, city driving is usually less efficient than highway driving.
Repeated acceleration from traffic lights requires additional energy, while idling consumes fuel without covering distance.
A regular i30 Sedan 2.0 petrol, for example, has an official urban consumption figure of 8.5 L/100km.
That is substantially higher than its extra-urban rating of 4.7 L/100km.
Which i30 Is Best for City Driving?
The i30 Sedan Hybrid is particularly attractive for urban commuting.
Its electric motor helps reduce the petrol engine's workload, while regenerative braking recovers some energy that would otherwise be lost.
The newer mild-hybrid i30 Hatch is another appealing option.
Although its 48-volt system cannot offer the same electric-driving capabilities as a full hybrid, it can still contribute to improved efficiency.
For regular city commuting, we would generally favour the hybrid if fuel savings are the primary objective.
Hyundai i30 Highway Fuel Consumption
Highway driving is where many conventional Hyundai i30 engines perform particularly well.
At steady speeds, the engine operates more consistently, avoiding the repeated acceleration associated with urban traffic.
The Australian MY25 i30 N Line Hatch has an official extra-urban fuel consumption figure of approximately 5.0 L/100km.
Meanwhile, the 2.0-litre i30 Sedan has a published extra-urban figure of 4.7 L/100km.
These values come from controlled test cycles and shouldn't be interpreted as guaranteed consumption at modern motorway speeds.
What Is the Best Speed for Fuel Economy?
The most economical cruising speed depends on the engine, gearing, road conditions, and traffic.
In general, moderate and consistent speeds help reduce petrol consumption.
Higher speeds increase aerodynamic resistance, meaning the engine must work harder to maintain momentum.
Cruising at 110 km/h will often consume more fuel than travelling at 90 km/h under otherwise comparable conditions.
However, we should always prioritise road conditions, traffic flow, and applicable speed limits.
Hyundai i30 Fuel Consumption in Australia
Australia is one of the markets where Hyundai i30 fuel economy is particularly relevant.
Long driving distances, motorway travel, urban congestion, and varying terrain can create very different fuel consumption results.
For example, driving through central Sydney or Melbourne during peak traffic places different demands on the engine than travelling along regional highways.
Fuel Economy in Australian Cities
In congested metropolitan areas, we should expect conventional petrol models to consume more than their official combined figures in many circumstances.
Frequent idling, air-conditioning use, short journeys, and repeated acceleration all influence consumption.
Hybrid models tend to offer an advantage in these conditions.
Fuel Economy on Australian Highways
For drivers regularly travelling between regional towns or covering long motorway distances, the Hyundai i30 can be an economical choice.
Its compact dimensions and relatively efficient engines make it suitable for extended journeys.
However, strong headwinds, steep climbs, high cruising speeds, and heavily loaded vehicles can increase fuel consumption.
We should judge efficiency using results from our normal driving routes rather than relying on a single journey.
Hyundai i30 Fuel Economy in Other Markets
Not every country receives the same Hyundai i30 engine range.
European and UK-market hatchbacks have been offered with smaller petrol engines and mild-hybrid technologies that differ from some Australian variants.
For example, published European WLTP figures for selected i30 models include:
| Engine | Official Combined Consumption |
|---|---|
| 1.0 T-GDi petrol | 5.4–6.4 L/100km |
| 1.0 T-GDi 48V mild hybrid | 5.3–6.2 L/100km |
| 1.5 T-GDi 48V mild hybrid | 5.5–6.5 L/100km |
| 1.5 DPi petrol | 6.0–6.8 L/100km |
These are published ranges for specific European specifications and model configurations, not figures that apply to every model year.
Also, European WLTP ratings and Australian ADR figures use different testing procedures, so direct comparisons require caution.
When evaluating a Hyundai i30, we should always check the specifications for the exact model, engine, transmission, and market.
How Many Kilometres Can a Hyundai i30 Travel on a Full Tank?
The Hyundai i30's driving range depends on its fuel tank capacity and average fuel consumption.
Some hatchback models use a 50-litre tank, while selected i30 Sedan variants have different capacities.
We can estimate theoretical driving range using the following formula:
Driving range = Fuel tank capacity ÷ Fuel consumption × 100
For example, an i30 consuming 5.6 L/100km with a 50-litre tank has a theoretical combined-cycle range of approximately 893 kilometres.
Hyundai i30 Fuel Tank Capacity and Range
| Model | Fuel Tank | Theoretical Range |
|---|---|---|
| i30 N Line Hatch MY25 | 50 litres | 893 km |
| i30 Sedan 2.0 petrol | 47 litres | 770 km |
| i30 Sedan Hybrid | 42 litres | 1,077 km |
| i30 N Hatch MY25 | 50 litres | 588 km |
These estimates use official combined consumption figures.
Actual driving range will vary, and we should not expect to use every litre in the tank before refuelling.
The vehicle's fuel warning system and remaining reserve also need to be considered.
How Much Does It Cost to Fuel a Hyundai i30?
Fuel costs are an important part of vehicle ownership.

Subaru Crosstrek Fuel Consumption Australia: Petrol vs Hybrid (2026 Guide)A small difference in consumption can translate into meaningful savings over several years.
Let's assume we drive 15,000 kilometres annually and pay AUD $2.00 per litre for petrol.
This is a hypothetical price used for comparison, not a current fuel-price quotation.
Estimated Annual Hyundai i30 Fuel Costs
| Model | Fuel Consumption | Annual Fuel Cost |
|---|---|---|
| i30 N Line Hatch MY25 | 5.6 L/100km | $1,680 |
| i30 Sedan 2.0 petrol | 6.1 L/100km | $1,830 |
| i30 Sedan N Line MY25 | 6.6 L/100km | $1,980 |
| i30 Sedan Hybrid | 3.9 L/100km | $1,170 |
| Earlier 2.0 petrol Hatch (auto) | 7.4 L/100km | $2,220 |
| i30 N Hatch MY25 | 8.5 L/100km | $2,550 |
The difference between the hybrid and the high-performance i30 N could reach approximately $1,380 per year under these assumptions.
Of course, actual savings depend on fuel prices, driving distances, and real-world consumption.
How to Calculate Your Own Fuel Expenses
We can calculate annual petrol costs using:
Annual fuel cost = Annual kilometres × (L/100km ÷ 100) × Fuel price per litre
Suppose we own an i30 that averages 6.5 L/100km.
If we travel 18,000 kilometres annually:
18,000 × 0.065 = 1,170 litres.
At $2.00 per litre, annual petrol expenses would be approximately $2,340.
This method works for any Hyundai i30 model.
Hyundai i30 MPG: Converting Fuel Consumption
Drivers in the United Kingdom and United States often prefer miles per gallon rather than litres per 100 kilometres.
However, UK and US gallons have different capacities, so the two MPG measurements are not interchangeable.
The table below provides approximate conversions.
| L/100km | UK MPG | US MPG |
|---|---|---|
| 3.9 | 72.4 | 60.3 |
| 5.0 | 56.5 | 47.0 |
| 5.6 | 50.4 | 42.0 |
| 6.1 | 46.3 | 38.6 |
| 6.6 | 42.8 | 35.6 |
| 7.4 | 38.2 | 31.8 |
| 8.5 | 33.2 | 27.7 |
Lower L/100km figures indicate better efficiency, while higher MPG values indicate better efficiency.
For example, a Hyundai i30 achieving 5.6 L/100km returns approximately 50.4 UK MPG.
That's a respectable result for a petrol-powered hatchback.
Is the Hyundai i30 More Fuel Efficient Than Its Rivals?
The Hyundai i30 competes with popular small cars such as the Toyota Corolla, Mazda 3, Kia Cerato, and Volkswagen Golf.
Each offers different engines, transmissions, and efficiency characteristics.
Hyundai i30 vs Toyota Corolla
The Toyota Corolla Hybrid is widely recognised for its efficiency, particularly in urban driving.
Its full-hybrid technology can offer an advantage over conventional petrol-only i30 models.
However, the Hyundai i30 Sedan Hybrid provides a more relevant comparison because it also combines petrol and electric propulsion.
The best choice depends on the exact specifications, purchase price, comfort, and ownership requirements.
Hyundai i30 vs Mazda 3
The Mazda 3 offers a refined driving experience and a range of petrol engines, depending on the market.
Fuel efficiency varies by engine, transmission, and model year.
The newer Hyundai i30 mild-hybrid models may offer lower official consumption than some Mazda 3 petrol variants, although comparisons need to be made using equivalent test cycles.
Both vehicles can be reasonable choices for drivers wanting a compact car with manageable fuel expenses.
Hyundai i30 vs Volkswagen Golf
The Volkswagen Golf has also been available with efficient small-capacity turbocharged engines and electrified powertrains.
Some Golf variants compete closely with the Hyundai i30 in official fuel consumption.
When comparing them, we should consider reliability, maintenance expenses, fuel requirements, and purchase price alongside efficiency.
A car that uses slightly less petrol is not necessarily cheaper to own overall.
Does the Hyundai i30 Use Regular Petrol?
Many Australian-market Hyundai i30 petrol variants can use regular unleaded petrol, although fuel requirements vary by engine.
For example, the MY25 1.5-litre mild-hybrid i30 Hatch is specified to run on 91 RON unleaded petrol.
Selected regular i30 Sedan petrol and hybrid versions also support 91 RON fuel.
However, high-performance versions such as the i30 N have different fuel requirements and may specify premium unleaded petrol.
Using higher-octane petrol does not automatically produce meaningful fuel savings in an engine designed for regular unleaded.
A vehicle calibrated to use 91 RON may not deliver enough additional efficiency from premium petrol to justify the price difference.
On the other hand, if an engine requires a higher octane rating, we should follow that requirement.
Always check the owner's manual and fuel filler information for the exact model.
Does the Hyundai i30 Mild-Hybrid System Save Fuel?
Yes, the mild-hybrid system can improve efficiency by assisting the petrol engine and supporting energy recovery.
However, it works differently from a full hybrid.
Mild Hybrid vs Full Hybrid
| Feature | Mild Hybrid | Full Hybrid |
|---|---|---|
| Petrol engine | Yes | Yes |
| Electric assistance | Yes | Yes |
| Regenerative braking | Yes | Yes |
| Electric-only propulsion | Generally no | Yes, under suitable conditions |
| External charging required | No | No |
| Urban efficiency potential | Good | Often better |
The i30 Hatch mild-hybrid system is designed to improve the efficiency of its petrol engine.
The i30 Sedan Hybrid offers more substantial electric propulsion capabilities.
For drivers primarily travelling in heavy city traffic, a full hybrid is generally the more economical option.
How to Improve Hyundai i30 Fuel Efficiency
Even if we already own a Hyundai i30, several driving and maintenance habits can help reduce petrol consumption.
1. Maintain the Correct Tyre Pressure
Underinflated tyres increase rolling resistance, forcing the engine to work harder.
We should check pressures regularly and follow the recommendations for our vehicle's load and tyre size.
2. Avoid Aggressive Acceleration
Rapid acceleration requires more fuel.
Smoothly increasing speed and anticipating traffic can help improve efficiency without significantly increasing journey times.
3. Maintain a Consistent Speed
Repeated acceleration and braking waste energy.
On suitable roads, maintaining a steady speed can help reduce fuel consumption.
Cruise control may also be useful on relatively flat highways when conditions permit.
4. Reduce Unnecessary Weight
Carrying heavy items increases the amount of energy required to accelerate and climb hills.
Removing unnecessary luggage and equipment can provide small efficiency improvements.
5. Keep Up With Scheduled Maintenance
Regular maintenance helps the engine operate as intended.
We should follow Hyundai's recommended service schedule, including the appropriate oil specification and replacement of filters when required.
Worn spark plugs, faulty sensors, or mechanical problems can increase fuel consumption.

Hyundai i30 Fuel Consumption in Australia6. Avoid Excessive Idling
Leaving the engine running while parked wastes petrol.
Modern start-stop systems can help reduce unnecessary idling in suitable conditions.
7. Use Air Conditioning Sensibly
Air conditioning requires energy and may increase petrol consumption.
We don't need to avoid using it, but maintaining a sensible cabin temperature can help reduce unnecessary demand.
8. Remove Roof Racks When Unnecessary
Roof racks and roof boxes increase aerodynamic drag.
At highway speeds, this additional resistance can noticeably affect fuel consumption.
Removing unused accessories helps the vehicle move through the air more efficiently.
Why Is My Hyundai i30 Using Too Much Fuel?
If our Hyundai i30 suddenly begins consuming more petrol than usual, several factors may be responsible.
Potential causes include incorrect tyre pressure, repeated short journeys, heavy traffic, changes in driving conditions, or overdue maintenance.
Mechanical problems can also contribute.
Common Mechanical Causes
Some possible issues include:
- Worn or incorrectly specified spark plugs.
- Faulty oxygen sensors.
- Engine temperature regulation problems.
- Dirty or restricted air filters.
- Dragging brakes.
- Fuel-system or engine-management faults.
These issues should not be assumed to be present simply because fuel consumption is higher than expected.
We should first compare consumption over several tanks under similar driving conditions.
If fuel consumption increases suddenly, particularly with warning lights or poor engine performance, professional diagnosis is advisable.
How to Measure Your Hyundai i30 Fuel Consumption
The onboard trip computer provides a convenient way to monitor fuel economy.
However, we can also calculate consumption ourselves using fuel receipts and distance travelled.
Step-by-Step Fuel Consumption Calculation
- Fill the fuel tank and reset the trip meter.
- Drive normally until the next refuelling.
- Fill the tank again to a comparable level.
- Record the litres added.
- Record the distance travelled since the previous fill.
- Divide the litres by kilometres and multiply by 100.
For example, suppose we travel 520 kilometres and use 34 litres of petrol.
34 ÷ 520 × 100 = 6.54 L/100km.
Our calculated average would therefore be approximately 6.5 L/100km.
Repeating this process over several tanks provides a more reliable picture of everyday fuel consumption than measuring a single short journey.
Is an Older Hyundai i30 Still Fuel Efficient?
An older Hyundai i30 can still offer acceptable petrol consumption, especially when properly maintained.
However, fuel efficiency varies significantly between generations and engine types.
Older diesel versions, where available, may offer particularly low fuel consumption on longer journeys.
Traditional naturally aspirated petrol engines often consume more than newer mild-hybrid alternatives.
What Should We Check When Buying a Used i30?
If fuel economy is important, we should examine:
- Exact engine and transmission.
- Model year and specification.
- Official fuel consumption rating.
- Service and maintenance history.
- Tyre condition and pressure.
- Evidence of engine-management problems.
- Previous usage patterns, where known.
A well-maintained older i30 may provide better overall value than a newer vehicle with a much higher purchase price.
The key is to balance fuel consumption against depreciation, insurance, maintenance, and the condition of the specific car.
Which Hyundai i30 Has the Best Fuel Economy?
Among the Australian variants discussed in this guide, the Hyundai i30 Sedan Hybrid offers the lowest official combined petrol consumption at approximately 3.9 L/100km.
The 1.5-litre mild-hybrid i30 Hatch is another efficient option, with its official 5.6 L/100km figure.
If we want an ordinary petrol sedan without a full-hybrid system, the 2.0-litre i30 Sedan offers competitive consumption at 6.1 L/100km.
Best Hyundai i30 for Different Drivers
| Driver Type | Suitable i30 Version | Main Advantage |
|---|---|---|
| Daily city commuter | i30 Sedan Hybrid | Low petrol consumption |
| Hatchback buyer | i30 1.5T Mild Hybrid | Efficiency and practicality |
| Everyday sedan driver | i30 Sedan 2.0 | Balanced running costs |
| Sporty daily driving | i30 Sedan N Line | Performance and usability |
| Driving enthusiast | i30 N | High-performance driving |
| Budget used-car buyer | Earlier i30 petrol | Potentially lower purchase cost |
There is no single ideal model for everyone.
We should choose according to our normal driving conditions, budget, and performance expectations.
Is the Hyundai i30 Economical to Own?
Fuel efficiency is only one component of total ownership costs.
Other important considerations include insurance, servicing, registration, tyres, repairs, and depreciation.
A highly efficient hybrid may save more petrol, but it could also have a higher purchase price.
Similarly, a used petrol i30 may consume more fuel while costing substantially less to purchase.
Why Total Ownership Costs Matter
Suppose one car costs $5,000 more to purchase but saves $300 per year in petrol.
Ignoring other differences, it would take more than 16 years of fuel savings to recover the additional purchase price.
On the other hand, a vehicle that saves $1,000 annually could recover a $5,000 premium in approximately five years.
These are simplified examples, but they demonstrate why fuel economy shouldn't be our only consideration.
