BYD Dolphin Mini, the best-selling electric car in Brazil, evaluated in São Paulo

Those considering purchasing a new vehicle or changing cars should consider electrified options, given that the Brazilian market for light electrified vehicles has more than doubled in twelve months. According to the Brazilian Electric Vehicle Association (ABVE), between January and June 2026, sales totaled 215,023 units, representing a 125% increase compared to the same period in 2025 (which registered 95,493 units). The average monthly sales during this semester was 35,837, and electrified vehicles achieved a 16% market share in the first half.

Analysis of the BYD Dolphin Mini on the streets of São Paulo

The Olhar Digital portal tested the BYD Dolphin Mini, which led sales in the segment, accumulating 35,680 sales in the analyzed period. The dimensions of the BYD Dolphin Mini are notably compact: 3.78 meters in length, 1.72 m in width, and 1.58 m in height, with a wheelbase of 2.50 m and a ground clearance of 155 mm. Despite its reduced size, the interior accommodates five passengers, and the trunk offers 230 liters, expandable to 930 liters with the rear seats folded down.

In urban environments characterized by heavy traffic, narrow streets, and parking difficulties, the car's size under four meters provides significant advantages, facilitating maneuvering and positioning, which generates a sense of control while driving.

Despite being a compact model, the comfort in the driving position was perceived as satisfactory, and the interior space is well utilized. The seats also contribute to this perception, and the driver can adjust the seat electrically in six positions, with the upholstery made of premium ecological leather. Although the author is 1.85m tall, he did not feel disproportionate to the steering wheel, but noted that a trip in the back seat would be uncomfortable for someone of his height.

The suspension, equipped with a McPherson setup in the front and a torsion beam in the rear, surprisingly performed well. The adjustment is smooth, and when driving through São Paulo's roads, the car handled the asphalt imperfections well, without excessively transmitting impacts and irregularities to the cabin, despite its inherent physical limitations due to its size.

Urban Focus and Performance

It is crucial to understand the niche market of the Dolphin Mini: it was not designed for off-road trails or long highway trips; its vocation is fundamentally urban. In this context, many decisions made by BYD make sense. The front electric motor generates 75 hp and 135 Nm of torque. Technical data indicates acceleration from 0 to 100 km/h in 14.9 seconds and a top speed of 130 km/h, in addition to offering four driving modes: Eco, Normal, Sport, and Snow.

However, the driving experience showed that maximum power does not entirely define an electric car focused on the city. In São Paulo traffic, the Dolphin Mini proved to be quite intelligent, responding promptly to the accelerator at low speeds, performing well at traffic lights, and having enough agility for typical urban maneuvers like overtaking and lane changes. Its dynamism lies precisely in the most common situations for the city driver.

The combination of reduced dimensions, light steering, and the immediate response of the electric motor makes driving the Dolphin Mini pleasant in the urban environment. Another aspect reinforcing its urban character is the battery, available in two configurations: 30.08 kWh or 38.88 kWh, offering declared PBEV ranges of 224 km and 280 km, respectively. AC charging reaches 6.6 kW, and DC charging can reach 30 kW in the smaller version and 40 kW in the larger one.

The vehicle also features VTOL functionality, allowing the battery to supply energy to external equipment. For daily commute trips, the range is adequate, enabling several days without needing a recharge, depending on mileage. If access to a charger at home or work is available, the value of the Dolphin Mini increases, as it can remain charging while parked.

The proposal to be a simple urban car did not imply neglecting technology or finishing quality, which differentiates the Dolphin Mini from competitors with similar prices but more basic interiors. The dashboard has a 7-inch screen, and the multimedia center has a 10.1-inch screen. The DiLink system supports Apple CarPlay and Android Auto, 4G connectivity, and voice commands. Furthermore, there are six speakers, two USB ports, and digital air conditioning. Some versions include inductive charging, although the author suggested a more discreet location for this in the São Paulo context.

Additional features include a 360-degree camera, which facilitates parking in tight spots, and three rear radars. In terms of safety, the car is equipped with ABS, stability and traction control, electronic braking distribution, hill start assist, tire pressure monitoring, electronic parking brake, and cruise control. Front and curtain airbags are present, and front side airbags are optional on the GS configuration.

After testing it in São Paulo, the best assessment is not to force the car to be something it is not. It is not ideal for those seeking high performance, large luggage capacity, or constant highway travel; it is a vehicle conceived primarily for the city. Within this proposal, the set works very well: it is externally compact, comfortable to drive, agile in traffic, easy to maneuver, and presents an attractive technological and finishing package for its class.

Although the term 'affordable' is difficult to apply to any new car in the current Brazilian scenario, considering the finish, embedded technology, driving experience, and the focus of the Dolphin Mini, it offers a highly competitive package. Its main strength is not trying to be a universal electric vehicle, focusing instead on being an excellent vehicle for daily urban life.

Flex Engine History: Brazilian Technology That Allowed for the Use of Different Fuels

The Flex technology, developed in Brazil, allows most current vehicles to use gasoline, ethanol, or a combination of both. This system was commercially launched in the country in 2003.

Initially, the creation of this technology served as a response to consumer distrust regarding alcohol, motivated by supply crises and price fluctuations of the product during the 1990s.

By offering the driver the freedom to choose the most economical fuel at the pump, the system quickly gained popular acceptance. More than two decades after its launch, the Flex engine is seen by the automotive industry as an option to reduce pollutant emissions, alongside electric cars.

Previously, the choice was restricted: the driver had to acquire a car designed exclusively for gasoline or another for hydrated ethanol. Due to the loss of credibility in alcohol-powered vehicles in the 90s, some drivers began mixing fuels themselves in the tank, a practice known as 'rabo de galo' mixture, which frequently resulted in mechanical problems in workshops.

It was in this scenario of difficulties that engineering identified an opportunity: to develop an engine capable of operating with any proportion of alcohol and gasoline without suffering damage.

Professor Renato Romio, responsible for the engines and vehicles department at the Mauá Institute of Technology, mentioned that there was a previous program, Proálcool, which was declining. He stated that the emergence of Flex cars allowed this program to be rescued, ensuring the maintenance of ethanol at gas stations.

Although the idea of a dual-fuel car already existed in the United States, where they used a sophisticated and costly tank sensor to monitor the mixture, Brazilian engineers opted for a more accessible approach. They dispensed with the tank sensor and used the lambda probe, a part already present in vehicles and significantly cheaper.

Positioned in the exhaust system, the lambda probe acts as an electronic detector. Instead of analyzing the tank contents, it examines the smoke generated by the combustion of the fuel exiting the exhaust. An embedded software, such as systems developed by Magneti Marelli or Bosch, interprets this data in real time. By detecting the composition of the ethanol and gasoline burn, the system makes automatic adjustments to the engine's operation.

With the technical solution established, manufacturers began a competition to introduce the innovation to the market. Volkswagen led the launch, presenting the Gol 1.6 Total Flex in March 2003. Subsequently, Fiat and Chevrolet followed with the Palio 1.3 and the Corsa 1.8, respectively, using the same technology, marking the beginning of the Flex car era in Brazil.

A crucial advantage of the Flex vehicle is the possibility of keeping pure ethanol available at gas stations. According to engineer Renato Romio, the Brazilian differential lies not only in the Flex technology but also in the availability of hydrated ethanol at stations, something other countries do not have.

The implementation of the Flex engine required engineers to solve practical issues to increase the longevity and ease of use of the cars. The first obstacle was material resistance, as ethanol causes corrosion in common metals. Therefore, manufacturers began to use more robust components in the construction of the engines.

Another problem was the cold start system, necessary because ethanol requires more heat to burn than gasoline. Flex cars came equipped with a small gasoline reservoir under the hood to inject some of this fuel on cold days, aiding ignition. With engineering advancements, systems were created that heat the fuel before combustion or inject it under high pressure directly into the engine, eliminating the need for this aid.

Currently, Flex technology is integrated into the energy transition movement alongside electric vehicles, starting with Flex hybrid cars, which combine an electric motor and an internal combustion engine. In these models, the battery assists during periods of lower energy demand, while the ethanol engine takes over when higher power or autonomy is needed, resulting in efficient and low-pollution vehicles.

The next stage involves converting ethanol into electricity. Brazilian researchers developed the microreformer, a component that extracts ethanol from the tank and converts it into hydrogen gas inside the vehicle itself. This hydrogen then undergoes a chemical reaction that generates electrical energy to charge the battery and move the automobile, allowing the driver to refuel with ethanol and drive an electric vehicle.

The professor at Mauá Institute considers the battery electric vehicle to be the future, but recognizes the importance of ethanol as a viable source for prolonged use until battery vehicles achieve large-scale application.
