Transportation Network Company (TNC) drivers are a critical segment in California’s transportation decarbonization strategy, but they face substantial barriers to electric vehicle (EV) adoption. This analysis investigates how California can overcome both affordability and adoption thresholds within the TNC driver segment to accelerate EV adoption and provide more equitable access to clean-transportation technologies. To accomplish this, we employ a model that combines affordability purchase methods and total-cost-of-ownership models. We then determine the requisite incentive for three all-battery electric vehicle (BEV) acquisition scenarios relative to an internal combustion engine vehicle (ICEV) baseline: a new BEV purchase, a used BEV purchase, and new BEV lease. We find that incentives on the order of $6,000 to $18,000 are required to achieve price parity with the ICEV vehicle, while much larger incentives of $32,000 to $58,000 are required to reach a predefined affordability threshold. In addition, we conducted a sensitivity analysis of the model’s key features, including vehicle MSRP, household income, charging costs, and weekly miles driven, to determine their relative influence on the requisite incentive amount. This analysis shows that substantial incentive amounts are required to enable affordable choices for many TNC drivers, particularly for new EV purchases.
