然而,市場成長的一大障礙是將馬達置於車輪內部所增加的非懸浮重量。這種額外的品質會對車輛的操控性和乘坐舒適性產生負面影響,需要採取技術手段來彌補。反過來,這又會增加製造成本和結構複雜性。
電動車(EV)的快速普及是全球輪內馬達市場的主要驅動力。這是因為輪轂馬達具有結構優勢,使其成為電動驅動的理想選擇。輪內馬達支援先進的扭力向量控制技術,透過最佳化空間佈局並實現每個車輪的獨立控制,從而提升電動車的安全性和操控性。凱利藍皮書(Kelly Blue Book)在2026年4月援引國際能源總署(IEA)的數據報道稱,到2025年,電動車將佔全球汽車銷量的25%,凸顯了這項技術快速成長的市場潛力。不斷擴大的電動車市場為輪內馬達提供了絕佳機遇,使其成為未來交通途徑的重要組成部分。
汽車工程和電動車平台領域的持續創新,透過克服傳統設計限制和提升馬達性能,正在推動市場成長。近期技術進步優先考慮成本效益、高功率密度和降低非懸浮質量,使得這些系統在各種車型中越來越受歡迎。例如,Elaphe Propulsion Technologies公司於2025年7月宣布,其Sonic X平台每輪功率可達300kW,重量僅增加25kg,相較於傳統電力驅動橋,效能顯著提升。除了這些技術里程碑之外,具體的生產數據,例如Protean Electric公司2024年1500台的產量,對於確保該技術的廣泛商業化和證明其實用性至關重要。
輪內馬達普及應用的主要障礙之一是車輛非懸吊重量的顯著增加。直接增加車輪的重量會對操控特性和乘坐舒適性產生負面影響,使現代消費者難以獲得他們所追求的平順靈敏的駕駛體驗。額外的重量會導致牽引力下降、操控響應遲緩以及懸吊系統變硬,所有這些都可能影響乘客的舒適性和車輛的穩定性。
為了解決輪轂馬達對車輛動力學的負面影響,製造商必須投入大量資金進行複雜的設計調整,導致研發和生產成本飆升。這種財務負擔可能會削弱輪內馬達車輛在競爭激烈的電動車市場中的經濟可行性。儘管整體電動車市場蓬勃發展,德國汽車工業協會 (VDA) 的報告顯示,到 2025 年德國電動車產量將達到 167 萬輛,同比成長 23%,但由於非簧載質量這一根深蒂固的問題,輪轂馬達技術未能充分利用這一成長勢頭。最終,無法克服這些根本性的性能缺陷仍然是限制輪內馬達市場全球擴張的主要阻礙因素。
模組化電動車架構的興起是塑造輪內馬達產業的重要趨勢,它帶來了更高的整合效率和更大的設計自由度。這種架構允許製造商利用統一的基礎結構,同時客製化車身和功能,這項策略與輪轂式馬達的獨立設計完美契合。透過最大限度地降低開發成本和複雜性,這種模組化方法使輪轂馬達系統成為各種車型的理想選擇。作為這項轉變的標誌,Protean Electric 於 2025 年 9 月宣布,其最新的「ProteanDrive」系統將於 2026 年開始生產,成本與傳統的雙電軸相當。這簡化了在各種模組化平台上的實施,有助於汽車製造商加速部署配備輪內馬達的電動車。
另一個重要的市場趨勢是輪內馬達技術在非公路車輛和商用車領域的應用。這些特殊用途的車輛需要高耐久性和高扭矩的動力裝置,而輪轂式馬達的高效封裝、獨立控制和直接驅動能力使其具有顯著優勢。隨著大型電動運輸車輛的轉型加速,輪內馬達的應用前景也日益廣闊。彭博專業服務公司(Bloomberg Professional Services)的數據顯示,截至2025年9月,電動卡車將佔全球銷量的約4%,其中中國市場在當年上半年的銷量約為8萬輛。這一穩步成長表明,輪內馬達的應用範圍正從傳統乘用車擴展到商用車領域,以滿足其對性能和效率的更高要求。
The Global In-Wheel Motor Market is expected to expand from USD 3.78 billion in 2025 to USD 5.66 billion by 2031, reflecting a compound annual growth rate of 6.96%. Also referred to as wheel hub motors, these devices are built directly into a vehicle's wheel hub, entirely replacing conventional drivetrains, axles, and differentials. This market's growth is heavily fueled by the rising worldwide transition to electric vehicles, capitalizing on benefits like optimized vehicle layout and individual wheel control that enables sophisticated torque vectoring. Data from the European Automobile Manufacturers' Association (ACEA) highlights this growing foundation for electric propulsion, noting that battery-electric vehicles accounted for 17.4% of all new car registrations in the European Union in 2025.

However, a major obstacle to market growth is the additional unsprung weight that comes from housing motors inside the wheels. This extra mass can adversely affect the handling and ride quality of a vehicle, necessitating engineering workarounds that ultimately increase both manufacturing expenses and structural complexity.
Market Driver
The surging popularity of electric vehicles serves as a major catalyst for the Global In-Wheel Motor Market, given that these motors provide structural benefits perfectly suited for electric propulsion. By facilitating better spatial layouts and allowing independent control over each wheel, in-wheel motors support advanced torque vectoring that enhances safety and handling in electric vehicles. As reported by Kelley Blue Book, referencing the International Energy Agency in April 2026, electric vehicles made up 25% of global car sales in 2025, highlighting a rapidly growing foundation for this technology. This expanding EV market offers a tremendous opportunity for in-wheel motors to establish themselves as essential elements of tomorrow's transportation.
Ongoing innovations in automotive engineering and electric vehicle platforms are also driving market growth by resolving older design limitations and boosting motor performance. Recent breakthroughs prioritize cost-efficiency, higher power density, and lower unsprung mass, which makes these systems increasingly attractive across multiple vehicle categories. For example, Elaphe Propulsion Technologies reported in July 2025 that its Sonic X platform delivers up to 300 kW per wheel with a weight penalty of just 25 kg, vastly outperforming conventional e-axles. These technical milestones, alongside tangible production achievements like Protean Electric manufacturing 1,500 units in 2024, are vital for securing widespread commercial adoption and proving the technology's viability.
Market Challenge
A prominent hurdle to the widespread adoption of in-wheel motors is the significant increase in a vehicle's unsprung weight. Adding mass directly to the wheels negatively affects handling traits and ride comfort, complicating the effort to deliver the smooth and responsive driving experience that today's consumers demand. This extra weight can result in decreased traction, sluggish handling responses, and stiffer suspension behavior, which together risk degrading passenger comfort and vehicle stability.
To counter these negative impacts on vehicle dynamics, manufacturers must invest heavily in complex engineering adjustments that drive up both development and production costs. Such financial burdens can render vehicles featuring in-wheel motors less economically viable within the highly competitive electric vehicle space. Even as the broader EV sector thrives-evidenced by the German Association of the Automotive Industry (VDA) noting a 23% year-over-year jump to 1.67 million electric cars produced in Germany during 2025-the persistent issue of unsprung mass prevents in-wheel technology from fully capitalizing on this boom. Ultimately, overcoming these fundamental performance compromises remains a major limiting factor for the global expansion of the in-wheel motor market.
Market Trends
The rise of modular electric vehicle architectures is a major trend shaping the in-wheel motor industry, offering streamlined integration and extensive design freedom. Such frameworks permit manufacturers to utilize uniform base structures while tailoring vehicle bodies and features, a strategy that pairs perfectly with the independent design of hub motors. By minimizing developmental expenses and complexities, this modular approach makes in-wheel systems attractive for a broad array of vehicles. Highlighting this shift, Protean Electric revealed in September 2025 that its newest ProteanDrive system would begin production in 2026 at a cost equivalent to conventional twin e-axles, thereby simplifying adoption into diverse modular platforms and helping automakers speed up the rollout of in-wheel-equipped EVs.
Another pivotal market trend is the application of in-wheel motor technology within the off-highway and commercial vehicle sectors. These specialized categories demand durable, high-torque mechanisms and gain immense value from the efficient packaging, independent control, and direct drive capabilities of hub motors. As the shift toward electric heavy-duty transport accelerates, it creates fresh avenues for in-wheel motor implementation. Data from Bloomberg Professional Services in September 2025 indicated that electric trucks accounted for nearly 4% of global sales, alongside roughly 80,000 units sold in China during the first half of the year. This steady expansion illustrates how in-wheel motors are moving past standard passenger cars to meet the rigorous performance and efficiency needs of commercial fleets.
