Toyota has long been synonymous with hybrid reliability, but its first dedicated electric vehicle, the 2026 bZ, reveals a surprising Achilles' heel: driver-assist technology. In a head-to-head test against the Tesla Model Y, the bZ delivers on range, price, and build quality—yet its advanced driver-assistance system (ADAS) lags far behind the gold standard set by Tesla's Autopilot.
Forbes tested both EVs side by side to evaluate real-world driver-assist performance. The bZ's system—Toyota Safety Sense 3.0—offers adaptive cruise control, lane-keeping assist, and automatic emergency braking. But compared to Tesla's Autopilot, which includes lane centering, Navigate on Autopilot for highway interchanges, and continuous over-the-air updates, the Toyota feels dated.
This gap matters because driver-assist technology is rapidly becoming the deciding factor for EV buyers. A 2025 JD Power study found that 58% of EV shoppers consider ADAS features a top-three purchase criterion. Tesla has cultivated a lead by treating software as the core product, with frequent updates that improve performance over time. Toyota, by contrast, has treated driver-assist as a static, feature-checklist item.
The test pitted the 2026 Toyota bZ (base price ~$42,000, 252-mile range) against the Tesla Model Y (base ~$44,990, 279-mile range). On the highway, the Model Y's Autopilot smoothly handled lane changes and merging, while the bZ's system often disengaged unexpectedly and felt less confident in curves. In stop-and-go traffic, both performed adequately, but Tesla's natural acceleration and deceleration felt more human-like.
Toyota has sold over 23 million hybrids globally, and its reputation for quality remains unblemished. Yet its conservative approach to ADAS—relying on tier-one suppliers rather than building software in-house—may cost it in the EV race. "Toyota's hardware is solid, but they're not iterating on the software side like Tesla or even Ford with BlueCruise," said Sam Abuelsamid, principal analyst at Guidehouse Insights. "That's a competitive risk as EVs commoditize battery and powertrain."
Looking ahead, Toyota plans to introduce its Arene operating system by 2028, which will enable more sophisticated ADAS and over-the-air updates. But that timeline may be too slow. Tesla is already working on its 'Full Self-Driving' v13, while Chinese rivals like BYD and XPeng are pushing hands-free highway driving into mass-market vehicles. The bZ's driver-assist shortfall won't kill Toyota's EV ambitions, but it signals a cultural divide: the world's largest automaker must decide whether to lead or follow in the software-defined era of electric mobility.

Tested: Toyota bZ Vs. Tesla Model Y — Driver-Assist Tech
The refreshed 2026 Toyota bZ excels at offering the essential EV basics but lags in driver assist technology, which will become de rigueur for EVs in the coming years.

Key Takeaways
- The 2026 Toyota bZ base price is ~$42,000 with 252-mile range, while the Tesla Model Y starts at ~$44,990 with 279-mile range.
- Toyota Safety Sense 3.0 lacks over-the-air updates, whereas Tesla Autopilot receives continuous software improvements.
- In highway testing, Tesla's lane centering and automatic lane changes performed more reliably than Toyota's system, which disengaged unexpectedly in curves.
- 58% of EV buyers consider ADAS features a top-three purchase criterion, according to a 2025 JD Power study.
- Toyota plans to launch its Arene operating system by 2028, which could close the ADAS gap, but competitors are already advancing hands-free driving in cheaper models.
Frequently Asked Questions
The Toyota bZ uses the Toyota Safety Sense 3.0 suite, which includes adaptive cruise control, lane-keeping assist, automatic emergency braking, and pedestrian detection. It does not include features like automatic lane changes or highway merging assistance that are found on Tesla's Autopilot.
Tesla's Autopilot offers more advanced functionality, including lane centering, Navigate on Autopilot for highway interchanges, auto lane changes, and continuous over-the-air updates. In Forbes testing, the Model Y's system felt smoother and more reliable than the bZ's, especially on curves and during heavy traffic.
Yes, Toyota's driver-assist systems meet global safety standards and have received high marks from organizations like IIHS and Euro NCAP. However, the system is less capable than competitors' offerings and may disengage in complex driving scenarios where Tesla's system would remain active.
No, the Toyota bZ does not have autonomous driving capabilities. Its driver-assist system is classified as Level 2, meaning it requires constant driver supervision. Tesla's Autopilot is also Level 2, but includes more advanced driver-assistance features.
The main limitations are the lack of over-the-air updates, no automatic lane change capability, less confident lane centering in curves, and occasional unexpected disengagement. The system also cannot handle highway interchanges automatically as Tesla's Navigate on Autopilot can.
As of 2026, Tesla's Autopilot remains the most refined and widely available driver-assist system, followed by Ford's BlueCruise and GM's Super Cruise. Toyota's bZ lags behind these offerings, though the company plans to release a more advanced system with its Arene operating system by 2028.
