Within a decade, the typical new car could drive itself, generate its own electricity from sunlight, and continuously exchange position and speed data with every other vehicle on the road, according to industry technology roadmaps reviewed by Live Science.
The convergence of three separate technologies — Level 5 autonomous driving, vehicle-integrated solar panels, and vehicle-to-everything (V2X) wireless communication — is the central bet automakers and regulators are making for the 2035 model year. Each technology already exists in limited form. The question is whether they can be combined at a cost consumers will pay.
Solar roofs currently add roughly 3 to 5 kilowatts of generating capacity at peak sunlight, enough to add 20 to 40 miles of range per day for a typical electric vehicle, according to figures from manufacturers including Toyota and Hyundai, both of which have tested solar-equipped prototypes. That would cover the daily commute of about 60% of American drivers, according to Federal Highway Administration trip data.
V2X systems, which let cars broadcast their location, direction, and speed to nearby vehicles up to 10 times per second, are further along. The National Highway Traffic Safety Administration proposed a rule in 2023 that would require V2X capability in all new light vehicles, citing the technology's potential to prevent hundreds of thousands of crashes annually. General Motors began shipping V2X-equipped Cadillac models in 2023.
Full self-driving remains the hardest piece. Tesla, Waymo, and Cruise have logged millions of autonomous miles, but no system has yet achieved the Level 5 designation — full operation without human oversight in all conditions — that the 2035 vision requires. Waymo's robotaxis, which operate commercially in Phoenix, San Francisco, and Los Angeles, still rely on detailed pre-mapped routes and remote human assistance for edge cases.
The payoff, if the three technologies converge, is a fleet that produces no tailpipe emissions, requires no driver attention, and avoids crashes by coordinating rather than reacting. The obstacles are equally concrete: solar panels add weight and cost, V2X requires a nationwide communication standard that does not yet exist, and autonomous software remains unproven in heavy rain, snow, and unmapped terrain.
Cost is the deciding factor. A 2024 analysis by the consulting firm McKinsey estimated that a fully equipped autonomous electric vehicle would carry roughly $10,000 to $15,000 in additional hardware over a comparable conventional car — a premium that would need to fall by more than half before mass adoption.
