With a budget of 150,000-200,000 yuan for a pure electric SUV, which cars would we actually consider? And why are more and more people willing to choose a pure electric SUV? Ultimately, at this price point, you need enough space for family use, as well as range and charging capability that can support commuting, school runs, and weekend trips. Looking around, the Changan Qiyuan Q06 and BYD Sea Lion 06 EV will most likely make the shortlist. Specifically, the Changan Qiyuan Q06 2027 700 Smart Premium Edition, after upgrading to the Tianshu Pilot Ultra package, has a limited-time price of 175,800 yuan, while the BYD Sea Lion 06 EV 2026 710 Long-Range Flagship Edition has a guide price of 179,900 yuan, a price difference of 4,100 yuan. Both cars have 700 km-class range and 7-second-class acceleration, with similar specifications on paper. What really needs to be compared is which one better understands family use.
（Changan Qiyuan Q06）
（BYD Sea Lion 06EV）
But after driving and riding in them, I found that the two cars have slightly different understandings of the word “family use.” Today, instead of talking about official rhetoric, I will discuss the real experience from multiple dimensions such as design, space, seats, equipment, and chassis, and see what differences the two cars have.
Exterior design: one takes a coupe-like approach, the other embraces ocean aesthetics
（Changan Qiyuan Q06）
（Changan Qiyuan Q06）
The Changan Qiyuan Q06 follows a coupe SUV route. The closed front face is paired with a through-type “smile light bar,” made up of 236 LEDs. The middle of the light bar is bent downward, and when lit it indeed looks like an upturned corner of the mouth, with very high recognizability. On the side, the standout features are frameless doors and semi-hidden door handles. All four doors are equipped with double-layer laminated glass, so sound insulation was not sacrificed for styling.
（Changan Qiyuan Q06）
At the rear is a through-type star ring taillight composed of 274 light beads, supporting customizable light language. The vehicle’s drag coefficient reaches 0.27, which is a relatively excellent level among SUVs in the same class; behind this is the Q06 team’s meticulous attention to design, such as frameless doors, low-drag exterior rearview mirrors, low-drag door handles, low-drag wheels, hidden wipers, and multi-duct airflow guide structures bringing all-round refined optimization, which together make the “0.27Cd” figure possible.
（BYD Sea Lion 06EV）
The Sea Lion 06 EV continues BYD’s Ocean Network design language, with split LED headlights paired with a closed front face, guide grooves on both sides of the front bumper, and a double-layer trapezoidal lower grille at the bottom. The body lines are much softer than the Q06’s and do not take an angular route. The 2026 model adds a Liuguang Silver color, and the overall style is rounded and easy on the eyes over time.
（BYD Sea Lion 06EV）
At the rear is Ocean Network’s signature ring-shaped through-type dual light bars, paired with a high-mounted brake light and a spoiler. The Sea Lion 06 EV’s body dimensions are 4810×1920×1675 mm, 27 mm shorter and 50 mm narrower than the Q06. There is no absolute good or bad at the exterior level: the Changan Qiyuan Q06 wants to win your favor quickly, while the Sea Lion 06 EV leans more toward “not getting tiresome even after looking at it for a long time.”
Interior design: both are clean and simple, but the atmosphere differs
（Changan Qiyuan Q06）
The Changan Qiyuan Q06’s instrument panel has a horizontal layered layout, with soft wrapping on the upper layer, a through-type trim panel in the middle, and a hollowed-out lower layer for storage. The 15.6-inch central control screen floats in the center, and a row of physical buttons is retained below the screen, so air conditioning and volume can be operated directly by touch. Directly in front of the driver is a 49-inch AR-HUD, whose projection area is considerably larger than the Sea Lion 06 EV’s 26-inch W-HUD. Vehicle speed, navigation, and driver assistance information are spread out more widely, so the driver does not need to switch their gaze back and forth between the instrument panel and central screen while driving.
（Changan Qiyuan Q06）
（Changan Qiyuan Q06）
A 15.6-inch ceiling-mounted entertainment screen hangs from the rear roof. On long trips, rear passengers can watch videos without lowering their heads and holding tablets. This is a feature the Sea Lion 06 EV does not have. In addition, the Changan Qiyuan Q06’s 256-color ambient light strips have a total length of 4450 mm, and the strips are recessed by 15 mm. When lit at night, the light diffuses out from the gaps, not harsh, and rather premium.
（BYD Sea Lion 06EV）
The Sea Lion 06 EV’s interior lines are softer, and the instrument panel extends to both sides. In the middle is a rotatable 15.6-inch central control screen with the built-in DiLink system. In front of the driver is a 26-inch W-HUD, whose area is a size smaller than the Q06’s. The displayed information is relatively concentrated and sufficient for daily use, but the layout of navigation and driver assistance information is not as effortless as the Q06’s.
（BYD Sea Lion 06EV）
There is no rear entertainment screen, so rear passengers mainly rely on phones or tablets to pass the time on long trips. In terms of materials, the Sea Lion 06 EV’s soft wrapping covers the areas frequently touched by hands, and the workmanship and seam treatment are faultless. The Twilight Blue color scheme is on the cool side and visually relatively plain.
（BYD Sea Lion 06EV）
The “divergence” between the two cars in the interior is essentially about whom the screens and entertainment resources are allocated to. The Changan Qiyuan Q06 enlarges the HUD area and adds a rear entertainment screen, giving both the driver and rear passengers corresponding information or entertainment outlets; the Sea Lion 06 EV concentrates the central screen and HUD on the driver’s side, keeping the rear simple. If you often take family on long trips, the Changan Qiyuan Q06’s rear entertainment screen and larger HUD area will have more practical value; if most of the time the car is used by two people, the Sea Lion 06 EV’s cabin layout is also completely sufficient.
Comfort features: Sea Lion 06 “stops in the front row,” Changan Qiyuan Q06 “shares the rain and dew evenly”
（Changan Qiyuan Q06）
Sitting in the front row of the Changan Qiyuan Q06, the seat’s specification list and the experience match up. The electric adjustment range is large enough, and ventilation is suction-type, so your back will not get sweaty in summer; the massage function is on the gentler side, not the hard mechanical feeling, and after driving for two or three hours on a long trip, turning it on for a massage really relaxes the lower back quite a bit.
（Changan Qiyuan Q06）
The front passenger seat has an electric leg rest and zero-gravity mode. When zero-gravity mode is activated, the whole body is semi-reclined and “floating,” which is much more comfortable than a normal sitting posture when resting in the car at noon or waiting while parked.
（Changan Qiyuan Q06）
（Changan Qiyuan Q06）
The real gap emerges in the rear row. The Changan Qiyuan Q06’s rear backrest supports 145° stepless electric adjustment, an angle close to semi-reclining, and the cushion length has not shrunk, so the thighs can be fully supported. The rear row also gets ventilation, heating, and massage. Together with the 15.6-inch ceiling-mounted entertainment screen, small table, electric side window sunshades, and privacy glass, rear passengers can adjust to a semi-reclined state on long trips; turn on massage, watch a video, or handle some work, and both comfort and convenience are quite well delivered.
（BYD Sea Lion 06EV）
The Sea Lion 06 EV’s front-row equipment is also not lacking. Electric adjustment, ventilation, heating, massage, memory, and front passenger leg rest are all provided. This high-spec model also has a 12-speaker Dynaudio sound system, a hot and cold refrigerator, and a fragrance system. The front-row comfort experience is basically on the same level as the Changan Qiyuan Q06, and the Dynaudio sound quality even has a slight advantage.
（BYD Sea Lion 06EV）
（BYD Sea Lion 06EV）
But the rear-row equipment logic is completely different. The Sea Lion 06 EV’s rear backrest is manually adjusted, and there is no ventilation, heating, massage, or rear entertainment; sound-insulating glass is also only given to the front row, not the rear. The cushion softness is good, and short trips are faultless, but the long-trip rear experience has an obvious gap compared with the Changan Qiyuan Q06—the backrest angle is not reclined enough, there is no ventilation in summer, no heating in winter, and if you want to watch something you can only hold up your phone or tablet yourself. The Sea Lion 06 EV concentrates comfort features on the two front seats, while the rear row is at a level of “space is sufficient, functions are basic.”
（BYD Sea Lion 06EV）
The difference between the two cars in comfort features is a different answer to the question of “who sits in the rear row.” The Changan Qiyuan Q06’s approach is that front and rear passengers are equally important. Especially in scenarios where there are elderly people and children at home and the whole family often travels, the “full-stage” rear row can indeed provide real comfort improvements. The Sea Lion 06 EV’s approach leans more toward two-person use as the main scenario, maxing out front-row equipment while the rear row meets basic riding needs.
Space performance: after sitting in the rear row, your body will tell you where the gap is
（Changan Qiyuan Q06）
（BYD Sea Lion 06EV）
The Changan Qiyuan Q06 has a wheelbase of 2940 mm, and the Sea Lion 06 EV has a wheelbase of 2820 mm, a difference of 120 mm. This number may not feel like much on a specification sheet, but after sitting in the rear row, your body will tell you where the gap is.
（Changan Qiyuan Q06）
I am 178 cm tall, and I adjusted both cars’ front rows to a normal driving position. Sitting in the Changan Qiyuan Q06’s rear row, my knees were still more than three fists away from the front backrest, and my feet could naturally extend forward under the front seats. The cushion length is sufficient, the thighs can be fully supported, and after adjusting the backrest angle to semi-reclined, the body weight is evenly distributed across the cushion and backrest. It is not an exaggeration to describe it as spacious and comfortable.
（BYD Sea Lion 06EV）
Switching to the Sea Lion 06 EV’s rear row, knee room is about a little more than two fists, and foot space is not as generous as the Changan Qiyuan Q06’s. The cushion softness is good, but the length is a bit shorter than the Changan Qiyuan Q06’s, so the front part of the thighs is slightly unsupported. The backrest angle is manually adjusted in two stages, and even at the most reclined position it is not as relaxed as the Changan Qiyuan Q06. If there is a family member taller than 180 cm, or if the rear row often carries three people, the Changan Qiyuan Q06’s longitudinal margin will be more effortless.
（Changan Qiyuan Q06）
（BYD Sea Lion 06EV）
In terms of the trunk, the Changan Qiyuan Q06 has a regular volume of 782 L, expanding to 2200 L with the second row folded; the Sea Lion 06 EV has 757 L regular and 1630 L after folding. Both cars are sufficient for daily use, but the Changan Qiyuan Q06 has nearly 600 L more expanded volume after folding. If you like long-distance road trips and weekend camping, the Changan Qiyuan Q06’s expandability will be more convincing.
（Changan Qiyuan Q06）
（BYD Sea Lion 06EV）
The gap in the front trunk should not be ignored either. The Changan Qiyuan Q06 has a 196 L electric front trunk, which can be opened by tapping the badge, and also has a drainage hole design. The Sea Lion 06 EV has a 142 L manual front trunk, a size smaller, and it is fine for charging guns and emergency tools; but if you want to put muddy shoes or wet fishing gear there, it will be less convenient.
Driver assistance and charging: the two cars took different paths
（Changan Qiyuan Q06）
First, driver assistance. The Changan Qiyuan Q06 discussed in this article, after the upgrade, is given a 256-line lidar and a J6P chip with 560 TOPS of computing power, laying a relatively solid foundation in perception hardware. But there is an easily confused point here: the Pro version itself does not currently provide urban pilot assistance, but it is 9,900 yuan cheaper. If you want urban pilot assistance from the factory, you need to upgrade to the Ultra version. The Sea Lion 06 EV comes standard with DiPilot 100, focusing on visual perception, with an Orin-N chip at 84 TOPS. Highway NOA and automatic parking can both be used, while urban NOA requires an optional DiPilot 300 for 12,000 yuan, making the purchase cost relatively higher.
（BYD Sea Lion 06EV）
In specific daily-use scenarios, the differences between the two cars show up in some finer places. For example, when driving on the highway in rain, the water mist kicked up by the car ahead can affect the camera’s vision. The Changan Qiyuan Q06’s lidar is less susceptible to water mist and can still follow the car stably; the Sea Lion 06 EV’s visual solution will increase the following distance in such road conditions and is more conservative in acceleration and deceleration. Of course, these scenarios are relatively extreme working conditions, and most of the time in daily use both cars perform fairly stably.
（Changan Qiyuan Q06）
In terms of charging, both cars use an 800V platform, but the path to achieving “fast” is different. The Changan Qiyuan Q06 uses 6C fast charging, taking about 9 minutes from 30% to 80%, and adding more than 300 km of range in 10 minutes. The premise for this speed is finding a matching 6C ultra-fast charging pile.
（BYD Sea Lion 06EV）
The Sea Lion 06 EV’s fast charging takes only 9 minutes from 10% to 97% on a dedicated pile, also very fast, and its low-temperature performance is a strong point. In an environment of minus 30 degrees, charging time is only 3 minutes longer than at room temperature, making winter use more worry-free for northern users. But if there is no BYD fast charging station and a third-party fast charging pile is used, the full-charge time will also be lengthened considerably.
Chassis: the two cars understand “comfort” differently
（Changan Qiyuan Q06）
The Changan Qiyuan Q06 uses an all-aluminum front double wishbone + rear five-link suspension, a configuration that is not common at this price point. The first impression when driving is that the chassis is willing to communicate with you. When you turn the wheel, the front end responds relatively quickly, and the rear follows closely; when passing speed bumps, the suspension compresses and rebounds crisply, with no extra up-and-down floating of the body. This tuning style is suitable for people who often drive on highways, or who do not want driving to be too boring. The feedback the chassis gives you is, “I know what the road surface is like, but I have handled it for you.”
（BYD Sea Lion 06EV）
The Sea Lion 06 EV’s Cloud辇-C takes another path, with the core logic of trying to make passengers feel as little road change as possible. When passing manhole covers, seams, and patched road surfaces, it absorbs vibrations relatively thoroughly, leaving only a faint blur when transmitted to the seats. But the cost is that road feel is filtered relatively cleanly, the driver’s perception of the road surface is not strong, and body roll during rapid lane changes is also more obvious. If the daily commute road conditions are average and the car often carries elderly people and children, the Sea Lion 06 EV’s style of “hiding all discomfort” will be more appealing; if you drive yourself most of the time and care about handling feedback, the Changan Qiyuan Q06’s chassis has more communication.
（Changan Qiyuan Q06）
（BYD Sea Lion 06EV）
Summary: the two cars differ by only 4,100 yuan in price, but their product logic is different. The Sea Lion 06 EV concentrates comfort features in the front row, and Cloud辇-C’s vibration filtering and BYD’s fast charging are also core advantages, making it suitable for users who mainly use the car as two people and do not use the rear row frequently. The Changan Qiyuan Q06 spends its cost on rear-row space, front and rear comfort features, chassis hardware, and driver assistance hardware redundancy, making it suitable for users whose rear row often carries family and who value long-trip riding experience. Which one is more suitable for you? I think the key is still to try it yourself to know for sure.
