2021 Toyota Mirai MODEL OVERVIEW

Pros

  • Long, low, RWD proportions
  • 400-mile range
  • Generous standard tech

Cons

  • Limited hydrogen infrastructure
  • Expensive enough to be a Lexus
  • Digital brake feel

The Mirai is Toyota's alternative-fuel futuremobile, powered by an electric motor fed from a hydrogen fuel cell. Toyota introduced the oddball as a 2016 model, exclusively offered in California, which is one of the few states with the hydrogen infrastructure to support such a vehicle. This year marks the introduction of a larger, more premium second-generation Mirai, now riding on a RWD platform shared with the Lexus LS. It competes with other fuel cell and electric vehicles including the Hyundai Nexo, Honda Clarity, and Tesla Model 3.

What's New

  • All-new second-generation Mirai on a larger RWD Lexus platform
  • Longer, lower, and wider than its predecessor
  • New infotainment tech
  • Longer range than last-gen model

What We Think

The new Mirai is so, so much better than the oddball ecomobile it replaces. A longer, lower, wider platform permits elegant new styling; it no longer feels like you're walking up to some dinky science experiment. Ride quality is smooth and easy-going, aided by the new model's additional wheelbase over its predecessor. The new model is quicker, too.

Weight balance is a perfect 50:50 this time around, which lends the Mirai surprising balance and grace navigating curvy roads. One aspect of the driving experience we don't love is the brake pedal, which feels wooden and artificial as a result of Toyota's poorly tuned brake-by-wire system. As we found in our First Test review, it can be difficult to brake smoothly. With decent range, a smooth drive, great looks, and a larger interior, the Mirai is a sweet zero-emissions cruiser—as long as you live somewhere with the hydrogen infrastructure to support it.

Performance and Range

Toyota claimed the redesigned 2021 Mirai would offer an upgraded powertrain with enhanced performance. System output from the electric motor comes to 182 hp and 221 lb-ft of torque, compared to its predecessor's 151 hp and 247 lb-ft. That motor now drives the rear wheels instead of the fronts. The 2021 car reaches 60 mph in 7.4 seconds, significantly quicker than its predecessor's 8.6-second run.

With to a hydrogen fuel cell with more capacity than that of the first-gen model, Toyota has targeted a 30 percent increase in driving range. The math checks out; the 2020 model was rated at 312 miles of range and the new Mirai is delivers 402 miles in XLE trim or 357 miles for Platinum models with bigger wheels. That's a lot of ground to cover before needing to stop to refuel, and the Mirai's equivalent of "gassing up" only takes five or 10 minutes.

Safety

Every new Mirai features Toyota Safety Sense 2.5+, the automaker's latest, most advanced collection of driver-assist active safety features. The suite includes automatic emergency braking with pedestrian detection, lane keep assist with lane centering, adaptive cruise control, automatic high-beams, and road sign assistance.

Cargo Space and Interior Room

The next-gen Mirai interior includes at least one major improvement over its predecessor: It seats five passengers instead of just four. The 2021 Mirai's longer wheelbase suggests it can offer more interior room than the model it replaces. At 42.2 inches of front legroom, the 2021 car is only negligibly smaller than the 2020 model's 42.5 inches, but that car's 30.1 inches of rear legroom disappoint in comparison to the redesigned Mirai's 33.1 inches. Cargo volume is rated at a relatively tight 9.6 cubic feet.

Technology

The second-generation Mirai includes a standard 12.3-inch touchscreen infotainment system and 14-speaker audio. Those are serious improvements over the outgoing model's 7.0-inch screen and 11-speaker sound system. Wireless Apple CarPlay and Android Auto are both standard.
