Through a Thousand Curves

Driving from Bangkok to Betong is not a trip most people casually decide to do especially when the destination is Amazean Jungle Thailand by UTMB, one of the world’s leading trail running events that brings together mountain runners, outdoor enthusiasts, and adventure seekers from across the globe to a small border town in southern Thailand. This year, the METROSOCIETY team headed south to join the race, bringing along runners, gear, and everything needed for days on the road toward a destination filled with mountains, rain, and thousands of winding curves.

 

The route from Bangkok through Prachuap Khiri Khan, Chumphon, Surat Thani, Songkhla, Hat Yai, before entering Yala and finally Betong, stretches roughly 1,140–1,200 kilometers according to Google Maps. And the closer you get to Betong, the more demanding the roads become. Endless corners, mountain roads, sudden rain, and long hours behind the wheel quickly turn this into more than just a road trip.

 

 

For this journey, we traveled in the BYD Sealion 6 DM-i an SUV that many people might initially see as just another practical family car. But after spending real time with it on a route like this, it revealed a completely different personality.

 

At a time when fuel prices remain part of every long-distance travel conversation, BYD’s DM-i technology genuinely changes the experience. It doesn’t feel like a traditional hybrid. Instead, it behaves much closer to an EV, with instant torque delivery, quiet cabin comfort, and smooth power transitions over long distances. Combined with BYD’s Blade Battery technology, the car delivers a driving character that feels refined and easy to live with in real-world conditions whether in the city or on highways stretching across the country.

 

One thing we noticed immediately after leaving Bangkok was how relaxed the car felt during long hours on the road. Through the endless straight highways of southern Thailand, theBYD Sealion 6 DM-i stayed quiet and composed, making it easy to settle into the drive with music playing softly in the background while the scenery slowly changed outside the windows. Inside, the cabin handled everything we brought without effort running shoes, race gear, luggage, cameras, clothing, and all the small essentials that naturally pile up during a multi-day trip.

 

But the real character of theBYD Sealion 6 DM-i started to appear after Hat Yai, when the roads narrowed and the mountain curves began. Some sections were wet from constant rain, others dark and foggy, yet the SUV never felt stressed. Overtaking trucks or climbing uphill roads felt smooth thanks to the immediate response from the electric motor. There was no dramatic engine noise or aggressive acceleration just a calm, continuous flow of power that made long-distance driving feel lighter and less tiring than expected.

 

What stood out most after using the car in real conditions wasn’t a specific number on a spec sheet, but how easy it made everything feel. The flexibility of the DM-i system meant we never had to constantly plan around charging stations like a full EV. If there was a charger during a stop, we plugged in. If not, we simply fueled up and kept moving. That balance between electric driving and the freedom of traditional fueling made perfect sense for a journey like this, where plans can change at any moment.

 

The final stretch into Betong became one of the most memorable parts of the trip. The roads were surrounded by mist, rain drifted in and out, and the curves never seemed to end. Yet inside the cabin, everything remained calm. The driver assistance systems worked quietly in the background without becoming intrusive, while the car still felt planted and reassuring even on wet roads at night. It became the kind of drive where you stop thinking too much and simply let the road unfold in front of you.

 

Arriving in Betong, the BYD Sealion 6 DM-i almost felt out of place in the best possible way. Surrounded by support trucks, adventure vehicles, and runners from different countries, the SUV quietly stood out with its modern design and clean silhouette. Every time we stopped for coffee or supplies, people would turn around, take another look, or ask about the car. It wasn’t attention-seeking. It simply carried a different kind of presence modern, understated, and surprisingly fitting for a town filled with travelers chasing the same sense of adventure.

And by the time race day arrived, one thing became very clear: the BYD Sealion 6 DM-i didn’t just bring the METROSOCIETY team to Betong it brought us there without draining our energy before the race even began. Because in the end, the best long-distance SUV may not be the loudest, the fastest, or the most extreme. Sometimes, it’s simply the one that makes a 1,000-kilometer journey feel quieter, easier, and more effortless from start to finish.
