Without the light effects that precede a big announcement but with the security of someone who knows they have something good on their hands. MG met us in Frankfurt, met us on the outskirts of the city and put it before our eyes. The car and its tools. The weapons to continue gaining ground in a battle that seems long. Because with a quick presentation and a talk with its managers, the Chinese company revealed the two great advances with which it intends to continue gaining ground in the European automobile market: a new hybrid system and, above all, its semi-solid state batteries that will arrive with the new MG4 Urban EVa kind of evolution of the current MG4 Electric with which it will coexist in the market. In 2025, MG was the brand with Chinese capital that achieved the best results in Europe. Also in our country, where it reached 45,163 registered units. The formula for success has been based on the launch of vehicles for the access range. Cars at low prices, very spacious and equipped. But, above all, very competitive if we compare them with the competition. The strategy is paying off. Both in vehicles with combustion engines, where the brand does not have to pay tariffs, and with the MG4 Electric, which became among the best sellers in many European countries. The recipe at that time was simple: attractive price, good interior space and versions with a lot of power. Now, MG seeks to take a qualitative leap. Continue convincing and gaining ground in those who are undecided. But, above all, they bring technology that is currently not available to any other brand. Some semi-solid batteries to capture the market Our gazes, therefore, were pointed at the stage where the brand representatives were passing, but what was truly important was behind us. There, behind a curtain, the new MG4 EV Urban, a compact electric car that wants to position itself as the most advanced electric car of the moment. At least if we pay attention to its battery. At 4.44 meters long, the new MG electric car is a canonical compactor, of those that continue to triumph in the European market. To test it we will have to wait a few months but we were able to sit in it for the first time and see first-hand that we are facing a qualitative leap in quality in the interior. The car does not represent an aesthetic revolution on the outside and, of course, is less striking than the current MG4 Electric. But packaging does win. Inside, materials have improved and the perception of quality has risen. The screens are accompanied by physical buttons to control the climate and volume with wheels and controls that offer good touch. The sound of the speakers surprised me with their good quality (yes, I have to say that I don’t have the best ear among the staff). Xataka). And it has interesting details such as the controls that we already saw in the MGS6 EV on the steering wheel or a slightly rough mobile phone wireless charging surface so that the phone does not move. The new MG4 We will talk about all this in greater detail when we can get our hands on it to taste it in motion. Until then we will delve into the technology with which they want to hit the table with batteries that they already mass-produce. They are called “MG SolidCore Battery”. Because the MG4 EV Urban will be the first electric car in Europe to use semi-solid state batteries. With the promise that the car will not face a superlative extra cost. On the contrary, they told us that it will move in figures similar to the current ones. At the moment, the MG bestseller is around 38,000 euros but with the brand’s aid and discounts it is currently below 28,000 euros. What are these semi-solid batteries? It is the first step before jumping to solid batteries, the great promise of the electric car. They are energy accumulators that improve each and every one of the current aspects of LFP or NCM batteries, the most common on the market. Currently, these batteries use electrolytes that use liquid electrolytes to move lithium ions between the electrodes and thus generate electricity. With each discharge, lithium ions travel from the anode to the cathode through the liquid electrolyte. There the electricity is produced that is used by the motors. With recharging, the electrolyte takes the opposite path. Solid state batteries promise to forget about this liquid. This will allow, if the technique advances sufficiently, to have batteries with very ambitious ranges (more than 1,000 kilometers are targeted), in a reduced size and with more powerful charging and discharging capacity. And maintaining their security. The semi-solid state battery is the intermediate step. MG claims that the electrolyte liquid takes up around 20% of a conventional battery right now. With its new batteries, that liquid barely reaches 5%. Solidifying that space allows them to increase the nominal voltage of the battery and therefore also improve energy density. MG points out that these new batteries reach a density of 400 Wh/kg. Part of the secret is that the mobility of lithium ions increases their possibilities, they go from moving in a one-dimensional (LFP) or two-dimensional (NCM) to three-dimensional movement using the solid electrolyte. What does this translate into? The batteries of the new MG4 Urban EV will be smaller but will be able to travel the same number of kilometers as the current model. Although no specific figures have been confirmed, the leap forward should be qualitative because It is an evolution that feeds on itself.. If the battery is denser, it can be smaller to travel the same number of kilometers. At the same time, the weight of this accumulator is lower and the car is more efficient, resulting in better consumption data and, therefore, autonomy. But it also has other types of advantages such as less … Read more
