CALIFORNIA CITY, Calif. – The Mojave Desert, known by locals as the "high desert," lies some 170 km northeast of Los Angeles, California. In the midst of this remote desert, along a desolate road, a signboard marked HYUNDAI appears out of nowhere.
Behind the sign, a vast area of over 1,700 hectares — more than twice the size of Seoul’s Yeouido Island – unfolds: The California Proving Ground for South Korea’s top automaker Hyundai Motor Group.
The automotive group, which owns Korea’s two largest car-making units, Hyundai Motor Co. and Kia Corp., built the vehicle test center, also known as the Mojave Proving Ground, in 2005 with an investment of 80 billion won ($60.5 million).
Situated between 600 meters and 1,200 meters (2,000-4,000 feet) above sea level, the Mojave Desert sits in the rain shadow of the southern Sierra Nevada mountains and coastal ranges of Southern California.
Named for the indigenous Mojave people, the desert is among the driest, and the site of Death Valley — the lowest point in the United States.
Originating from the Spanish, Mojave is also spelled Mohave, and represents a brand Kia proudly offers as its largest SUV.

The annual average temperature at the location is 39 degrees Celsius. In summer, the surface temperature rises to 54 degrees Celsius. In winter, it drops to zero. The winds are strong enough to boast the United States' largest wind power generation site.
Merely placing vehicles in such harsh conditions is probably all that is needed to show how durable and well-built a car is.
"In many states, including California, Texas and Arizona, surface temperatures are high, causing pavement damage. Thus, they [road builders] deliberately create gaps in the roads to account for asphalt expansion," said Lee Kyung-jae, chief researcher at Hyundai and Kia America.
"To ensure ride comfort and durability on such roads, our tests are conducted in similarly rigorous environments."

Amid the desert's extreme and often-scorching temperatures, the Mojave test center conducts off-road tests on ride comfort, braking performance, noise, vibration and more.
Hyundai and Kia ensure that their vehicles meet rigorous US safety standards by launching vehicles only after they successfully undergo harsh tests at the proving ground, officials said.
The test center includes circuits, off-road tracks, slopes and even roads that simulate US road conditions.
Hyundai and Kia said they're now shifting their test focus to electric vehicles and SUVs, by implementing a more rigorous set of driving tests for their lineup of eco-friendly vehicles.

The critical aspect of testing Hyundai and Kia’s EVs is assessing the vehicles' ability to withstand the additional weight pressure on their suspension, tires and car body, said a Hyundai Motor Group official.
The proving ground is also equipped with a 10.3-km-long oval track on which the carmakers test their vehicles at speeds of up to 200 km per hour.
STEEP SALES GROWTH
Hyundai and Kia’s efforts are generating tangible results, as shown by their steep sales growth in the US.
The Kia Mohave The conglomerate said Hyundai, Kia and its premium brand Genesis sold a combined 1.65 million vehicles in the US market last year, up 12.1% from the year prior.
With their sales performance, the automotive duo ranked fourth, following GM, Toyota and Ford.
The Kia EV9 SUV won the North American Car, Truck and Utility Vehicle of the Year (NACTOY) 2024 — Kia’s second such feat following NACTOY 2023 for its EV6.
“It is no exaggeration to say that the Mojave Proving Ground has played a big role in enhancing Hyundai’s status in the SUV and EV segments in the US,” said a Hyundai Motor Group official.
