Kia recorded its highest-ever first-quarter sales in the global market in the first quarter of 2026, breaking into the 4% range for the first time with a 4.1% global market share.
A Major Transformation of the Market Landscape: Two 'Historical Events'
In the spring of 2026, two historical records were simultaneously set in the domestic automotive market.
One is the collapse of a 28-year-old order in the domestic car market, and the other is the sudden dominance of foreign electric vehicle brands, which have seized a share approaching 30% of the imported car market. Both events converge on the same root: a sign that the wave of electrification is fundamentally altering brand rankings and market dynamics.
In April 2026, Kia climbed to the top spot in domestic sales by selling 55,045 units in the domestic market, a 7.9% increase compared to the same month last year. For the first time in 28 years since being acquired by Hyundai Motor Group in 1998, Kia surpassed Hyundai Motor, which had previously held the senior position. Beyond simple monthly statistics, this was a symbolic scene suggesting the possibility of a realignment of status within Hyundai Motor Group.
Even more dramatic changes unfolded in the imported car market. According to the Korea Automobile Importers & Distributors Association (KAIDA), Tesla sold a total of 20,964 units in the first quarter of 2026, taking the No. 1 spot among imported car brands with a 25.53% market share. This is a staggering 335.1% increase compared to the same period last year, and the first time Tesla has ranked first on a quarterly basis since entering the Korean market in 2017.
Cumulative performance through April was even steeper, with Tesla registering 34,154 cumulative units from January to April this year, capturing a 29.41% share of the imported car market and establishing a dominant solo regime.
Domestic Car Market: The Solidity of the 'Hyundai-Kia Two-Party System,' but Cracks Beginning to Form
Looking first at the overall domestic passenger car market landscape, Hyundai Motor Group's absolute superiority remains intact. As of 2025, the combined sales of Hyundai and Kia reached 1,098,487 units, accounting to 91.1% of all domestic finished cars. The combined market share of the three mid-sized companies—Renault Korea, KG Mobility, and GM Korea—stood at a mere 8.9%.
This composition is basically maintained in 2026 as well. Domestic passenger car brand market shares in February 2026 were tallied in the order of Kia (43.7%), Hyundai (39.5%), Genesis (9.2%), KGM (4.4%), Renault Korea (2.4%), and Chevrolet (0.8%). When Genesis is combined with Hyundai Motor Group, Hyundai and Kia exhibit an overwhelming market share of 92.4%.
However, cracks began to appear in this seemingly solid structure precisely in April 2026.
Behind the collapse of Hyundai Motor's domestic sales, which dropped 19.9% year-on-year, lay complex factors beyond a simple contraction in demand. Due to parts supply disruptions caused by a fire at a supplier, production of major models such as the Palisade and G80 decreased, leaving Hyundai with 54,051 units sold—a 19.9% decline compared to the previous year.
Conversely, Kia widened the gap on the strength of its electrification lineup. Eco-friendly lineups such as electric vehicles (up 131.3%) and hybrid vehicles (up 12.6%) drove Kia's performance, leading to the assessment that "the 'Sorento, Carnival, and Sportage' triangular formation was the primary contributor to overtaking Hyundai Motor."
The bestselling car landscape is also noteworthy.
On an annual basis for 2025, the top-selling domestic car was the Kia Sorento, which was the only model to surpass 100,000 units (100,002 units), followed by the Hyundai Avante (79,335 units), Kia Carnival (78,218 units), Kia Sportage (74,517 units), and Hyundai Grandeur (71,775 units) to form the top 5. This landscape did not change significantly entering 2026.
In February 2026, the Sorento ranked first in new registrations; even in a situation where new registration volumes for most top-tier models decreased, the Sorento defended its throne with a somewhat wide margin over the runner-up. The proportion of hybrid models among Sorento vehicles registered in January and February reached 74.6%.
Genesis: Premium Defense Faces Direct Hit from 'Imported Car Offensive'
Genesis, the premium brand of Hyundai Motor Group, maintains a stable 9-to-10% market share within the domestic car ecosystem, but it is being placed on the defensive in competition with imported cars.
Genesis, which handles the premium market, took a direct hit from the offensive of imported brands in the first quarter of 2026, plunging 16.4% compared to the previous year. The direct factor cited is that Tesla has begun absorbing premium demand—the core customer base of Genesis—with its 40 million to 60 million KRW electric vehicle lineup.
On an annual basis for 2025, Genesis's bestseller was the G80 at 41,291 units, ranking 13th overall. For Genesis, it is currently launching a counterattack by strengthening its electrification portfolio, such as unveiling the GV60 Magma high-performance electric vehicle in the first half.
The Three Mid-Sized Brands: Facing the Wall of Reality and Seeking Breakthroughs via New Cars
The three mid-sized companies—Renault Korea, KG Mobility (KGM), and GM Korea (Chevrolet)—are struggling between survival and rebound strategies in 2026 as well. The circumstances of the three brands differ significantly from one another.
Renault Korea faced considerable hardship in the first quarter of 2026 due to declining sales of the Grand Koleos, but it is aiming for a turnaround with the new Filant vehicle, which began deliveries in March.
Renault Korea succeeded in rebounding its performance in March by selling 8,996 units, a 9% increase compared to the previous year. The new Filant vehicle, which started deliveries last month, settled into the market with 4,920 units sold, and hybrid models accounted for 90.5% of domestic sales to drive performance. However, it is experiencing volatile trends, such as plunging 40.5% year-on-year again in April.
KGM is performing relatively well among the three mid-sized companies. Powered by the popularity of newly launched SUV models such as the Musso and Torres, KGM recorded 10,746 units in the first quarter of 2026, a sharp surge of 45.2% year-on-year, making it the sole mid-sized company to perform well. In particular, it is solidifying its unrivaled position in the pickup truck segment.
The domestic sales situation of GM Korea (Chevrolet) is the most difficult. Chevrolet received a dismal report card of 686 new vehicle registrations for the month of February 2026, failing to even defend a 1% market share. This is a figure far smaller even than BYD (957 units), which ranks seventh among imported car brands. However, it still maintains global competitiveness in exports led by the Trax Crossover, a trend where its status as a production base exclusively for exports is virtually solidifying.
Imported Car Market: Tesla's Solo Run and 'Three-Way Restructuring'
Korea's imported car market in 2026 is truly a continuous series of Tesla shocks. No matter how quarterly and monthly statistics are sliced, the conclusion is one. Tesla has captured the summit of the imported car market for the very first time, and that momentum is accelerating rather than slowing down.
New registrations of imported passenger cars in the first quarter of 2026 reached 82,286 units, surging 35.7% from the same period last year. Amid the expansion of the entire market, the domestic market share of imported passenger cars in the first quarter recorded 22.3%. Following the surpassing of a 20% annual imported car market share for the first time last year, it continues to rise.
Two core factors lie behind Tesla's rapid rise. In mid-January, Tesla lowered the price of the Model 3 Standard RWD to 41.99 million KRW. Factoring in subsidies, this meant entering the 30 million KRW range became possible. The effects of the price cut and changes in supply strategy converged, allowing Tesla to surpass 10,000 monthly sales in March for the first time as an imported car brand. The previous record high was 9,546 units set by Mercedes-Benz in December 2020.
BMW and Mercedes-Benz still maintain the No. 2 and No. 3 spots in imported cars. As of the first quarter of 2026, BMW took second place with 19,368 units (23.58% share) and Mercedes-Benz took third with 15,862 units (19.32% share). However, amid Tesla's rapid advance, the market shares of both brands dropped by more than 5 percentage points.
Below fourth place, the rise of Chinese cars draws attention. BYD grew its presence by ranking fourth in the first quarter with 3,968 units (4.83% share). Lexus (3,755 units, 4.57%) and Volvo (3,628 units, 4.42%) followed behind.
BYD's growth rate is particularly steep. The mid-sized SUV Sea Lion 7 accounted for approximately 47.1% of total sales, and the compact electric SUV Atto 3 for about 38.3%, together driving over 85% of total sales volume. By presenting actual purchasing prices millions to nearly 10 million KRW cheaper than equivalent domestic models such as the Kia EV5 and Hyundai Ioniq 5, BYD absorbed consumers who had been hesitating to purchase high-priced electric vehicles.
Conversely, Volkswagen, once a powerhouse in the imported car market, is showing a disastrous downward trend. While overall imported car sales in the first quarter increased by 35% compared to the same period last year, Volkswagen managed to sell only around 1,290 units, slipping down to the 1% market share range.
Fuel-Type Paradigm Shift: Electric Vehicles Surpass Hybrids for the First Time
As noteworthy as the changes in brand market share is the transition of trends by fuel type.
In March 2026, 16,249 electric vehicles were sold in the imported car market, recording a 47.8% share. This is a figure that surpassed hybrids (14,585 units, 42.9%), which had maintained consistent strength, for the very first time. An inflection point where EVs overtook hybrids to establish themselves as the primary fuel type—at least in the imported car market—arrived in the first half of 2026.
A heavy concentration on hybrids is also prominent in the domestic car market. The hybrid proportion of the Sorento reaches 74.6%, and hybrid demand is overpowering internal combustion engines in major models such as the Avante and Palisade as well.
This is the result of a high-oil-price environment rapidly realigning consumer choices. When international crude oil prices skyrocketed following the outbreak of the US-Iran war on February 28, 2026, consumers' purchasing choices were swiftly restructured. In the used car market in March, electric vehicle transactions surged 29.5% compared to the previous month.
Structural Implications: The Change Is Not a Temporary Phenomenon
The changes in the domestic automotive market in the first half of 2026 should be read as a sign of structural transition rather than temporary ups and downs of specific brands.
First, Hyundai Motor and Kia's 91% monopoly structure will not be shaken for the time being, but within that structure, Kia's standing has risen to a level threatening Hyundai. If the phenomenon of Kia outperforming Hyundai in electrification strategy and SUV/RV lineups repeats, the very method of allocating strategic resources within the group could change.
Second, an imported car market share of 22% is not merely a number. In the first quarter of 2026, the top three brands (Tesla, BMW, Mercedes-Benz) account for approximately 68% of the market, showing a clear concentration phenomenon. If Tesla maintains the No. 1 spot on an annual basis as well, an increasing number of brands will need to fundamentally re-examine their domestic premium and electric vehicle market strategies.
Third, the entry of Chinese brands led by BYD has now become a 'reality' rather than an 'experiment.' With global electric vehicle offensives intensifying further as brands like Zeekr and Xpeng also probe entry into Korea alongside Tesla and BYD, forecasts suggest that domestic automakers' electrification response strategies will determine the success or failure of defending their home turf moving forward.
The domestic automotive market is undergoing its most rapid restructuring right now. Kia's domestic sales reversal, Tesla taking No. 1 in imported cars, and BYD's rapid settlement. The fact that all three events occurred simultaneously in the same quarter clearly proves that 2026 is a true inflection point for the Korean automotive industry.
