BYD Dolphin Surf or Toyota C-HR Plug-in Hybrid – which car is more profitable over 10 years of operation and 100,000–120,000 km?Electric car or plug-in hybrid – which investment is wiser? More and more Bulgarian drivers are facing the dilemma of choosing a 100% electric car or a plug-in hybrid. One of the most interesting clashes at the moment is between the new BYD Dolphin Surf and the Toyota C-HR Plug-in Hybrid. Both cars use modern technologies, offer low energy consumption and promise significantly lower operating costs compared to traditional gasoline and diesel models. But which one is more profitable if you plan to drive it for 10 years and travel a total of 100,000–120,000 kilometers? Let's look at all the main costs. We compare two completely different approaches BYD Dolphin Surf BYD Dolphin Surf is a fully electric car equipped with the proven Blade Battery (LFP). Its main features are: no internal combustion engine; no multi-gear gearbox; no exhaust system; no clutch; no turbocharger; no engine oil change. The design is significantly simpler, which means fewer potential repairs. Toyota C-HR Plug-in Hybrid Toyota uses one of the most reliable hybrid systems in the world. The car combines: a gasoline engine; an electric motor; a high-voltage battery; an automatic transmission; cooling systems for both the engine and the electrical part. The advantage is that the car can run on both electricity and gasoline. Energy consumption This is the first thing that interests almost every buyer. BYD Dolphin Surf The average real consumption is approximately: 13–15 kWh per 100 km When charging at home, the electricity consumption remains significantly lower than that of gasoline. Over 120,000 km, the total electricity consumption is usually significantly lower than the fuel costs of a car with an internal combustion engine, with the specific difference depending on the prices of electricity and petrol. Toyota C-HR Plug-in Hybrid If charged daily, the car can cover a large part of its daily routes on electricity alone. However, on longer journeys, the petrol engine is used more and more often. In real-world use, the average consumption is usually: around 1–3 litres per 100 km on short journeys with regular charging; around 5–6 litres per 100 km on long trips out of town. This means that in mixed use, the total energy costs will be higher compared to a fully electric car. Service costs This is where the biggest differences begin. BYD Dolphin Surf Regular maintenance mainly includes: air conditioning filter; brake fluid; coolant (if specified in the service plan); chassis inspection; battery diagnostics; 12-volt battery check. No: oil change; oil filter; engine air filter; fuel filter; timing belt or chain; spark plugs; turbocharger; exhaust system; DPF filter; EGR valve. Toyota C-HR Plug-in Hybrid In addition to the electrical system, the gasoline engine also needs to be serviced. This means: engine oil change; oil filter; air filter; cabin filter; spark plugs; coolant; brake fluid; periodic hybrid system check. Although Toyota is one of the most reliable brands, servicing remains more complicated and expensive than that of an electric vehicle. Battery – is there any reason to worry? BYD Blade Battery uses LFP technology, which is known for: very low degradation; high safety; long service life. With a mileage of 100–120 thousand kilometers, a significant loss of capacity is usually not expected. Toyota Toyota's hybrid system has proven its reliability. With such mileage, a high-voltage battery usually does not cause problems. The advantage is that the battery is smaller and operates in a more limited charge range, which reduces its load. Which car has more potential components for repair? BYD The main components are: electric motor; inverter; gearbox; high-voltage battery; on-board charger. Mechanically, the car is significantly simpler. Toyota In addition to all the electrical components, the car also has: gasoline engine; fuel system; exhaust system; engine cooling; lubrication system; numerous additional mechanical components. Therefore, the number of potential points of failure is greater. Which car will be worth less in 10 years? This is one of the most difficult questions. Toyota traditionally retains a high residual value thanks to its excellent reputation and high demand for used cars. With BYD, the residual value is still more difficult to predict, since the brand is relatively new to the European market. However, if interest in electric cars continues to grow and the model becomes established, its value may remain competitive. Reliability after 10 years With a mileage of 100–120 thousand kilometers, both cars should work without serious problems if serviced according to the manufacturer's recommendations.
BYD's advantage is the smaller number of mechanical components that can wear out. Toyota's advantage is its long-term experience in the production of hybrids and a well-established service network.

Which car is more profitable? If: you have the possibility of home charging; you drive up to about 12,000 kilometers per year; the majority of routes are urban and suburban; you are looking for the lowest possible running costs, the BYD Dolphin Surf is the more economical choice to own over the next 10 years.
However, if: you often travel long distances; you do not have reliable access to charging infrastructure; you want to rely on both electricity and petrol, the Toyota C-HR Plug-in Hybrid offers more flexibility. Conclusion With a mileage of 100,000–120,000 kilometres over 10 years, the difference between the two cars is not determined only by electricity or petrol consumption. More important are the total cost of ownership – servicing, consumables, the likelihood of repairs and the durability of the main components. For drivers who can charge at home and use the car mainly for daily trips, the BYD Dolphin Surf has the potential to offer a lower total cost of ownership thanks to its simpler design, low service costs and durable LFP battery. For its part, the Toyota C-HR Plug-in Hybrid remains an excellent choice for people who often travel long distances and seek maximum flexibility without dependence on the charging infrastructure.
At PlanetBatt.bg, we recommend that when buying a new or used electric vehicle or plug-in hybrid, you always pay attention not only to the price, but also to the long-term operating costs. Checking the high-voltage battery, the condition of the 12-volt battery and professional diagnostics can save significant money over the years and help make an informed choice.
