Fiat and Cadillac Top Legacy Automakers in US Electric Vehicle Sales Share
In the first half of 2026, Fiat led all legacy brands with 43.9% of its sales being electric, followed by Cadillac at 30.7%. Among auto groups, BMW Group had the highest EV share at 5.7%, with Hyundai-Kia at 4.2% and GM at 3.6%. The data shows that most traditional automakers still have low electric vehicle penetration.
In the first quarter, Fiat led legacy brands with 43.9% EV share, though its tiny sales volume (155 units) raises questions about its ranking. Cadillac followed at 30.7%, while Volvo Cars was the only other brand above 10%. By the second quarter, Cadillac rose to 35.4%, and Porsche surpassed 10%, while Volvo fell to 4.7%.
Among auto groups, BMW Group topped both quarters, rising from 5.7% to 6.0% EV share. General Motors jumped from third to second in Q2, reaching 5.0%, pushing Hyundai-Kia to third despite their own increase to 4.5%. Subaru also showed a significant leap, climbing from 2.1% to 4.2% between quarters.
The uneven EV adoption among legacy brands could shape consumer choices, as buyers seeking electric options may gravitate toward leaders like Cadillac and BMW Group. This disparity may pressure lagging automakers to accelerate their electrification roadmaps to remain competitive. Additionally, the slow overall penetration rates could influence policymakers and infrastructure planners, who may need to adjust timelines for charging networks and emissions targets based on actual market uptake.
