In-Depth Analysis Report on Xiaomi YU7's Winter Range Competitiveness

Based on collected data and technical analysis, we now present a comprehensive market research report.

According to Autohome’s 2025 Winter Range Test data, Xiaomi YU7 demonstrated excellent range performance in the test [1]:

Test Version	CLTC Range	Actual Measured Range	Range Retention Rate	Test Environment
Long-Range Rear-Wheel Drive Version	835km	687km	83.6%	Beijing, 10℃
Long-Range Four-Wheel Drive Pro	770km	-	-	-
Long-Range High-Performance Four-Wheel Drive Max	760km	-	-	-

On January 10, 2026, Lei Jun posted on Weibo: “I have full confidence in Xiaomi YU7’s winter performance, and welcome more car owners to share videos of driving it in Northeast China” [2]. Previously, Lei Jun has repeatedly emphasized that as a “northern car company”, Xiaomi set the goal of becoming the “king of pure electric vehicle winter range” at the very beginning of its car-making venture [1].

In the largest-scale winter test conducted by Autohome (test location: Yakeshi, Inner Mongolia; test temperature: -10℃ to -25℃ extremely cold environment), the range retention rate performance of various models is as follows [3]:

Vehicle Category	Representative Model	Range Retention Rate
Mid-to-High-End Family Pure Electric Sedan	Xpeng P7 Four-Wheel Drive	53.9%
Mid-to-High-End Family Pure Electric Sedan	BYD Yangwang U7 Four-Wheel Drive	51.8%
Mid-to-High-End Family Pure Electric SUV	Tesla Model Y Four-Wheel Drive	35.2%
Sub-Flagship Large 6-Seater Pure Electric SUV	Li Auto i8 Four-Wheel Drive	34.8%

: In extremely cold environments, the overall range retention rate of pure electric SUVs is significantly lower than that of sedans. Xiaomi YU7 achieved a range retention rate of 83.6% in the “quasi-winter test” environment of 10℃, which is significantly ahead of Tesla Model Y Rear-Wheel Drive’s 59.9% [4].

Based on industry test data, the impact of low temperature on driving range follows these patterns [5]:

• Normal Temperature Environment (10℃)
  : High-quality models can achieve over 80% range retention rate
• Low Temperature Environment (-10℃)
  : Generally 30%-40% range loss
• Extremely Cold Environment (-20℃)
  : Range loss can exceed 50%

Based on this, we estimate the range performance of Xiaomi YU7 in extremely cold environments:

Ambient Temperature	Estimated Range of Xiaomi YU7	Estimated Range of Tesla Model Y
10℃ (Measured)	687km	470km
-10℃	~520km	~370km
-20℃	~420km	~290km

The core parameters of the three models are compared as follows:

Parameter Index	Xiaomi YU7 Rear-Wheel Drive	Tesla Model Y Long-Range Rear-Wheel Drive	Zeekr 7X 100kWh
Price	253,500 Yuan	288,500 Yuan	269,900 Yuan
CLTC Range	835km	821km	802km
Battery Capacity	96.3kWh	78.4kWh	103kWh
100km Power Consumption	13.3kWh	13.5kWh	14.2kWh
0-100km/h Acceleration	5.88 seconds	5.6 seconds	3.8 seconds (Four-Wheel Drive)
High-Voltage Platform	800V	400V	900V
Fast Charging Time	0.35 hours	1.18 hours	0.18 hours
Drag Coefficient	0.245Cd	-	-

Based on a five-dimensional weighted analysis covering driving range (25%), battery capacity (20%), energy efficiency performance (20%), price competitiveness (20%), and brand premium (15%):

Ranking	Model	Weighted Comprehensive Score
1	Xiaomi YU7 Rear-Wheel Drive	8.85 points
2	Tesla Model Y Long-Range Rear-Wheel Drive	8.47 points
3	Zeekr 7X 100kWh	8.32 points

Xiaomi YU7 comes standard with an 800V high-voltage platform, which has significant advantages over Tesla Model Y’s 400V platform [6]:

• Fast charging speed increased by over 100% (0.35 hours vs 1.18 hours)
• Higher energy transmission efficiency, lower range loss
• Better heat control, beneficial for winter battery management

Lei Jun emphasized that Xiaomi Automotive “attaches great importance to winter driving experience” [1]. The YU7 is equipped with:

• Heat pump air conditioning system (40% more energy-efficient than PTC heaters)
• Intelligent battery preheating function
• Waste heat recovery from motor/electronic control systems

Xiaomi YU7 achieves an ultra-low drag coefficient of 0.245Cd, which is outstanding among mid-to-large SUVs, directly reducing high-speed energy consumption by approximately 15%.

:

Advantage Dimension	Current Advantage	Sustainability	Analysis Basis
Driving Range	835km, ranked first in the segment	Medium	Zeekr 7X has reached 802km, Tesla’s long-range version 821km, the gap is narrowing
Winter Range Retention Rate	83.6%, leading	High	More extreme cold measured data is needed for verification; thermal management system is the core competitiveness
Charging Speed	Advantage of 800V platform	High	Zeekr’s 900V platform is faster, but YU7 already meets mainstream demand
Cost-Effectiveness	Starting at 253,500 Yuan	High	Obvious price advantage, Xiaomi has strong cost control capabilities
Brand Premium	New entrant	Uncertain	Takes time to accumulate; SU7’s reputation is key

After the release of Autohome’s test results, doubts were raised. Blogger Chen Zhen pointed out that “at 10 degrees Celsius, this is just an ordinary range comparison test of three models”, and believed that the “winter test” label may mislead consumers [4]. This reflects:

• The 10℃ environment cannot fully represent extreme cold winter working conditions
• Consumers need to pay attention to real performance in extreme weather
• Xiaomi YU7 has not yet conducted public tests in -20℃ extremely cold environments

• Tesla has launched the updated Model Y Long-Range Rear-Wheel Drive with an increased range of 821km (priced at 288,500 Yuan) [7]
• Zeekr 7X adopts a 900V platform, with faster charging speed (10.5 minutes from 10% to 80%) [8]
• Brands such as BYD and NIO continue to launch long-range models

After the Xiaomi SU7 accident in March 2025, brand trust was affected to a certain extent. Lei Jun admitted in a live stream that “I’m scared of being trolled, I can’t sleep” [9]. Although YU7 has comprehensively upgraded safety configurations (standard lidar, 2200MPa “Xiaomi Super Steel”), it will take time to rebuild consumer confidence.

Xiaomi YU7 achieved an 83.6% range retention rate in a 10℃ environment, proving the technical advantages of its thermal management system and 800V platform. However, its performance in extremely cold environments (-20℃) still requires more measured data for verification. According to industry rules, the actual range of YU7 in extremely cold environments is approximately 420km, which can still meet most usage scenarios.

• Short-Term (Within 1 Year)
  : Xiaomi YU7 has obvious competitiveness in the 250,000-300,000 Yuan price segment, with comprehensive advantages in driving range, price, and charging efficiency
• Mid-Term (1-2 Years)
  : Competitor iterations may weaken some advantages, requiring continuous technological innovation and cost optimization
• Long-Term (Over 2 Years)
  : Brand building and user reputation accumulation are the keys to determining the stability of its market position

Comparison Dimension	Xiaomi YU7	Tesla Model Y	Zeekr 7X
Driving Range	★★★★★	★★★★☆	★★★★☆
Winter Range	★★★★★ (To be verified)	★★★☆☆	★★★★☆
Charging Speed	★★★★☆	★★★☆☆	★★★★★
Brand Value	★★★☆☆	★★★★★	★★★★☆
Cost-Effectiveness	★★★★★	★★★☆☆	★★★★☆

• Users in Cold Northern Regions
  : It is recommended to wait for more measured data in extremely cold environments, or choose the YU7 four-wheel drive version (stronger snow adaptability)
• Users Mainly for Daily Commuting
  : The YU7 Rear-Wheel Drive (253,500 Yuan) offers the best cost-effectiveness, with an 835km range enabling “one charge per week”
• Users with Frequent Long-Distance Travel
  : The YU7 Max version (329,900 Yuan) has a 760km range + 5.2C ultra-fast charging, eliminating range anxiety
• Brand-Sensitive Users
  : Tesla Model Y has high brand premium and good residual value, suitable for brand-oriented consumers
