In the 150.000–200.000 RMB range of new energy SUVs, the BYD Tang DM-i has consistently led the market as a pioneering force and has enjoyed strong sales. With BYD’s release of its 5th-generation DM technology, offering improved fuel economy and enhanced power, the Tang DM-i is now updated with this cutting-edge powertrain system. On October 25. BYD launched the 2025 Tang DM-i, centered around the 5th-generation DM power upgrade, new body colors, and blackened decorative accents. Across the lineup, FSD variable damping shock absorbers are standard, while the higher-end models are equipped with the advanced Yunnian C intelligent damping control system. Recently, we took a close look at the 2025 Tang DM-i Yunnian flagship model to assess its real-world performance.
The exterior design retains the signature “Dragon Face” look with a large hexagonal grille, creating a bold and prominent impression. The inner grille's dragon-scale mesh adopts a gradient color for a more three-dimensional appearance. The 2025 model introduces a new “Unbounded Gray” paint option with blackened accents on the upper trim, grille frame, and front lip, giving the vehicle a fresher, more youthful vibe.
From the side, the design is sleek and low-slung, with a moderate wheelbase and even front and rear overhangs. The roof has a slight downward slope, creating a floating roof effect with the concealed D-pillar. The wrap-around black side skirts add a subtle rugged charm without overdoing it, keeping a refined, urban feel. Details include two-tone exterior mirrors with integrated turn signals and cameras, though the camera is quite prominent. Traditional door handles are retained, with front-row keyless entry, rear privacy glass, and front multi-layer soundproof glass as standard.
In terms of dimensions, the vehicle measures 4870 mm in length, 1950 mm in width, and 1725 mm in height, with a 2820 mm wheelbase. As a mid-size SUV, the wheelbase isn’t particularly long, but thanks to a relatively flat roof and ample length, all models feature a 7-seat layout. Compared to the Chery Fengyun T10. another 7-seater, the Tang DM-i is larger in size, while the Deep Blue S07 has a longer wheelbase but only fits five due to its steeply sloped rear window.
Another update is the 20-inch two-tone Y-spoke wheels, adding a sporty touch. The tire specification is 255/50 R20. providing good grip and pairing with the Giti P80 series for improved handling and wet-road traction.
The rear styling is unchanged, featuring a slightly sloped rear window, a wrap-around roof spoiler, and an eye-catching taillight with a Chinese knot design. Additional vents on each side of the bumper add to the sporty look.
The cabin layout combines dark and light tones for a warm, sophisticated ambiance. The 12.3-inch fully digital instrument cluster and 15.6-inch rotating touchscreen are standard for interaction, with the system upgraded to the high-level DiLink 100 smart cockpit. The top two models add a HUD (heads-up display). All but the base model feature 31-color ambient lighting and a 12-speaker Dynaudio sound system.
The dual-spoke multifunction steering wheel is covered in synthetic leather, providing a good grip. Buttons and toggles on the horizontal spoke control the standard DiPilot L2-level driving assistance system, which includes full-speed adaptive cruise control, lane-keeping, and centering features.
The 12.3-inch digital instrument screen has been updated with a new UI, featuring three display sections: central driver-assist info, a left section for trip computer data, and a right section for entertainment and vehicle controls. The HUD offers improved clarity with dynamic directional arrows.

The latest system includes customizable wallpapers and a quick-access toolbar, with smooth touch response and fast connectivity. Voice commands recognize four zones and support continuous conversation. The 360-degree panoramic camera offers clear images with adjustable views.
The gear console design remains unchanged, with a compact and sleek electronic shifter at the center and essential physical buttons around it. A dual-cup holder sits under a front panel cover, and a 50W wireless phone charger is provided in front of the center armrest. The armrest storage space is moderate.
The top model seats are genuine leather, while lower trims use synthetic leather. Contact surfaces feature diamond stitching and perforations for better support. The padding is slightly firm, providing solid support, with broad side bolsters and an arched headrest for lateral support. The front seats offer extensive adjustments, including four-way lumbar support, leg support, ventilation, heating, and massage functions, with memory and height adjustments for the driver’s seat.
The 2+3+2 seven-seat configuration is standard across the lineup. The second-row seats are also leather with thick padding and manual fore-aft and recline adjustments, offering great adaptability. Adjusting the seat back fully, a 175 cm tall passenger has ample leg and headroom. A folding armrest with dual cupholders, rear AC vents, and USB and Type-C ports are provided. A panoramic sunroof is also standard.
The third-row seats are relatively thin and lower-set. With the second-row seats adjusted for an adult passenger’s legroom, third-row leg and headroom are just adequate, though leg positioning is a bit cramped for taller passengers.

Both rear seat rows fold in 5:5 and 4:6 configurations, offering high flexibility. The power tailgate with position memory is standard, while the top trim includes hands-free operation.
