EV vs Diesel vs Petrol: 5-Year Cost of Ownership in Latvia 2026 (TCO Compared)

The question "EV or diesel?" isn't about which car is cheaper in the showroom — it's about how much it costs you over 5 years in total: fuel, servicing, tax, insurance and depreciation. That's the TCO (Total Cost of Ownership), and this is exactly where an EV often beats both diesel and petrol.

TL;DR: at a realistic 15,000 km/year, an EV charged mostly at home typically costs several thousand euros less over 5 years than a comparable petrol car, and roughly matches or undercuts a diesel. The big wins: "fuel" at ~€4/100 km (EV at home) versus ~€13/100 km (petrol ~7 L × €1.866/L) and ~€10.70/100 km (diesel ~6 L × €1.789/L); servicing ~35–45% lower; and in Latvia an EV is exempt from the vehicle operation tax (TEN). The historical downside was a higher purchase price — but with Chinese EVs priced ~22–34% below their direct European rivals, that gap is narrowing.

What actually goes into a 5-year TCO?

The purchase price is just the visible tip of the iceberg. The true cost of running a car for 5 years has six components:

1. Purchase price (or lease deposit + interest). Traditionally an EV costs more, but the gap is shrinking.
2. Energy — fuel or electricity. This is the EV's biggest advantage.
3. Servicing and repairs — oil changes, filters, brakes, clutch, exhaust. The EV is radically simpler here.
4. Tax — vehicle operation tax (TEN), registration. EVs are exempt from TEN in Latvia.
5. Insurance (OCTA + comprehensive). Broadly comparable; newer, more powerful EVs may carry slightly higher comprehensive premiums.
6. Depreciation — usually the single largest cost of owning any new car.

Key point: a lower sticker price often hides higher "invisible" costs (fuel, servicing, depreciation). TCO compares correctly — the whole 5-year sum, not just the price tag.

Charging vs fuel: what does 100 km cost in Latvia?

This is the biggest day-to-day difference. Fuel prices in Latvia in 2026 are, indicatively, petrol ~€1.866/L and diesel ~€1.789/L (June data, check the latest). Home electricity is, indicatively, ~€0.22/kWh all-in.

| Vehicle type | Consumption | Unit price (indicative) | EUR/100 km | |---|---|---|---| | EV — at home | 18 kWh | €0.22/kWh | ~€4.00 | | EV — public DC | 18 kWh | €0.40/kWh | ~€7.20 | | Diesel | 6 L | €1.789/L | ~€10.70 | | Petrol | 7 L | €1.866/L | ~€13.10 |

At 15,000 km/year that translates into these annual fuel costs:

• EV at home: ~€600/year
• Diesel: ~€1,610/year
• Petrol: ~€1,960/year

Conclusion: charging at home makes an EV's "fuel" roughly 3× cheaper than petrol and ~2.7× cheaper than diesel. It's exactly this gap that compounds into thousands of euros over 5 years. For a detailed charging breakdown, see our charging-cost article.

Assumptions (stated honestly): 18 kWh/100 km, petrol 7 L/100 km, diesel 6 L/100 km; prices are 2026 indicative. If you only charge in public, the EV advantage shrinks, but most owners charge at home 80–90% of the time.

Why does servicing an EV cost less?

An electric motor is radically simpler than a combustion engine. A typical ICE car has ~2,000 moving parts in the engine and transmission; an EV has only a few dozen. That drives lower servicing costs:

• No oil changes. No engine oil, oil filter, or air/fuel filter replacements.
• No clutch, exhaust, spark plugs or timing belt. All of these are recurring costs on an ICE car.
• Less brake wear. Regenerative braking slows the car with the motor, so pads and discs last noticeably longer.
• Less heat and vibration — lower overall wear.

International data puts EV servicing costs at, indicatively, ~35–45% lower than a comparable ICE car (sources: AAA, Edmunds, manufacturer data — directional, foreign markets). For Latvia that's roughly ~€200–400/year saved on servicing.

Important nuance: EV "servicing" shifts toward tyres (more weight and torque wears rubber faster) and possibly battery coolant / software. But the battery usually carries a 3–8 year warranty (our partner china-cars.online's models come with an EU warranty of 3 years / 100,000 km plus CATL battery coverage).

Tax and depreciation: where does the big difference hide?

Vehicle operation tax (TEN)

In Latvia in 2026, an EV that runs on electricity only is exempt from the vehicle operation tax (TEN) — including for commercial use. Plug-in hybrids get reduced terms. Petrol and diesel cars pay TEN based on CO₂ emissions or (for older cars) engine displacement — indicatively tens to a few hundred euros per year depending on the car. (Indicative — work out the exact figure for your model with the tax calculator.)

Depreciation

Depreciation is usually the largest cost of any new car. Historically EVs depreciated faster (battery worries, fast-moving technology), but that's levelling out as the EV market matures. Practical drivers:

• Battery health (SoH). Buyers assess remaining battery capacity. Modern LFP batteries (made by CATL) degrade slowly and tolerate many cycles — which supports residual value.
• Warranty at resale. Remaining factory warranty (e.g. 3 years / 100,000 km) makes a used EV more attractive.
• Purchase price. The lower the starting price, the smaller the absolute amount you can lose at all. This is exactly where a ~22–34% lower Chinese-EV price helps.

Honest take: depreciation is hard to forecast — it depends on the model, the market, and battery health. We deliberately keep it qualitative in our TCO model rather than inventing precise percentages.

Break-even mileage: at what point does the EV win?

The break-even logic: the more you drive, the faster lower running costs repay a higher purchase price. The simplified principle:

• Low mileage (≤7,000 km/year): fuel savings are small, so if the EV is much pricier in the showroom, an ICE car can stay cheaper for the whole ownership period.
• Medium mileage (~12,000–18,000 km/year): the typical Latvian case. Here the EV's fuel + servicing + tax savings (indicatively ~€1,500–2,000/year versus petrol) usually repay the price gap within a few years.
• High mileage (≥25,000 km/year): the EV wins decisively and quickly — which is why many taxis and fleets switch to EVs.

Bottom line: the break-even point depends on (a) the showroom price gap and (b) your mileage. Shrink the price gap (e.g. with a more affordable EV) and break-even arrives sooner even at medium mileage.

A worked example with stated assumptions: EV vs diesel vs petrol over 5 years

Let's compare honestly. Assumptions (indicative, 2026): 15,000 km/year × 5 years = 75,000 km; the EV is charged mostly at home (€0.22/kWh, 18 kWh/100 km); petrol 7 L/100 km × €1.866/L; diesel 6 L/100 km × €1.789/L. Servicing and tax are indicative. We keep purchase price and depreciation out of the table (they depend on the specific model), but comment below.

| Cost item (5 years) | EV (at home) | Diesel | Petrol | |---|---|---|---| | Energy / fuel | ~€2,970 | ~€8,050 | ~€9,800 | | Servicing and repairs | ~€1,500 | ~€3,000 | ~€3,000 | | TEN (operation tax) | €0 | ~€500–1,000 | ~€500–1,000 | | Running cost total (excl. price/depreciation) | ~€4,500 | ~€11,500–12,000 | ~€13,300–13,800 |

Reading it: on running costs alone (fuel + servicing + TEN), the EV saves ~€7,000–9,000 over 5 years versus petrol and ~€7,000 versus diesel. That sum partly or fully offsets a higher purchase price — and if the EV's purchase price isn't much higher (as with Chinese EVs), the overall TCO tilts toward the EV even at medium mileage.

Add purchase price and depreciation for the specific model, and you have the full balance sheet. This is exactly why the purchase-price gap is decisive — and an affordable EV closes it best.

All figures are indicative for 2026. The real outcome depends on your mileage, contract, season and the specific model.

Where does the EV-vs-ICE gap get small? Affordable models

All of the TCO maths hinges on one variable: how much more the EV costs in the showroom. The smaller that gap, the faster lower running costs pay off. This is exactly where Chinese EVs help, offering comparable or better technology at ~22–34% lower prices than their direct European rivals.

| Model | Technology | Price (~incl. VAT) | Direct EU rival | Saving | |---|---|---|---|---| | Deepal S07 | CATL, HarmonyOS, ~475 km WLTP | ~€34,700 | BMW iX3 ~€52k | ~31% | | Xiaomi SU7 Max | 101 kWh CATL, 800V, 830 km CLTC, 673 hp | ~€38,800 | BMW i5 ~€64k | ~33% | | AVATR 06 | Changan+Huawei+CATL, 800V, Huawei ADS | ~€45,000 | BMW i4 / Audi A6 e-tron | ~18–31% | | Li Auto L6 | EREV up to 1,390 km CLTC, 408 hp AWD, 5★ C-NCAP | ~€49,800 | BMW X3 / Audi Q5 e-tron | ~23% |

Prices are shown incl. VAT (so the comparison with European showroom prices is fair); china-cars.online prices are listed ex-VAT (+~20%). Every model comes with an EU warranty of 3 years / 100,000 km plus CATL battery coverage, in stock, with 2–7 day delivery. china-cars.online is our trusted partner in Latvia.

Why do Chinese EVs cost less? Not because of worse quality, but because of manufacturing economics: massive scale, deep vertical integration (in-house CATL batteries, chips, software), gadget-style development cycles with OTA updates, fierce domestic competition, and selling factory-direct.

So: EV, diesel or petrol?

• Choose an EV if you drive at least moderately (~12,000+ km/year), can charge at home, and want the lowest running costs plus the tax exemption. Break-even comes sooner when the purchase-price gap is small.
• Diesel still makes sense for very high long-distance mileage without convenient charging — but fuel and servicing costs stay high, and you still pay TEN.
• Petrol is cheapest in the showroom but the most expensive to run per 100 km — best suited to low mileage.

Frequently asked questions

EV or diesel — which is cheaper over 5 years in Latvia?

At medium mileage (~15,000 km/year), an EV charged mostly at home is usually cheaper to run: fuel is ~3× cheaper, servicing ~35–45% lower, and TEN is €0. Diesel only makes sense for very high long-distance mileage without convenient charging. Check the exact tax with the calculator.

How much does 100 km cost: EV vs diesel vs petrol?

Indicatively for 2026: EV at home ~€4/100 km, EV public DC ~€7.20/100 km, diesel (~6 L × €1.789) ~€10.70/100 km, petrol (~7 L × €1.866) ~€13.10/100 km. Figures are directional — check current fuel and electricity prices.

Is an EV exempt from tax in Latvia?

In 2026 an EV running on electricity only is exempt from the vehicle operation tax (TEN) — including for commercial use. Plug-in hybrids get reduced terms. Check your specific situation with the tax calculator (indicative, based on current law).

Why is servicing an EV cheaper?

An electric motor has far fewer moving parts than a combustion engine: no oil changes, clutch, exhaust or spark plugs. Regenerative braking spares the brakes. The result is servicing costs roughly 35–45% lower (foreign data, directional).

How fast does an EV lose value?

Historically EVs depreciated faster, but this is levelling out as the market matures. Residual value is supported by good battery health (SoH), remaining warranty, and a low starting price. The exact percentage is hard to forecast — it depends on the model and market.

What's the break-even mileage for an EV?

It depends on the showroom price gap and your annual mileage. At medium mileage (~12,000–18,000 km/year) with a small price gap, the EV's running-cost savings repay the purchase price within a few years; at high mileage, sooner still.

Is diesel still worth it in 2026?

Diesel mainly makes sense for high long-distance mileage without convenient charging, since its L/100 km is lower than petrol. But fuel (~€1.789/L) and servicing stay high, and you still pay TEN — so total costs are often higher than an EV.

Do EV costs rise sharply in winter?

In cold weather consumption rises ~20–35% (cabin heating, battery warm-up), so winter EV "fuel" at home can climb to ~€5.50/100 km. That's still well below petrol and diesel levels.

How safe are Chinese EVs and their batteries?

Our partner's models use CATL batteries (the world's largest maker, supplying Tesla/BMW/Mercedes), often long-life LFP, and come with an EU warranty of 3 years / 100,000 km plus CATL coverage. Some models (e.g. Li Auto L6) hold 5★ C-NCAP. More in the Chinese-EV section.

Where can I find and compare affordable EVs in Latvia?

Start with the Chinese-EV roundup (800V, CATL batteries, ~22–34% cheaper than EU rivals), and the fuel/electricity maths in detail in our charging-cost article.
