2017 Toyota Mirai: New Car Review

If you’re looking for information on a newer Toyota Mirai, we’ve published an updated review: 2019 Toyota Mirai Review

The future: available now. At least, that’s what the advertisements say about the 2017 Toyota Mirai, a hydrogen fuel-cell vehicle that, in many ways, drives like an EV, refuels as quickly as a regular old gasoline car and emits nothing but water. It also looks futuristic, if a bit garish, and comes packed with the latest infotainment gadgets and safety gizmos.

But is the Mirai really the future? We’re not so sure. For starters, its design is a bit compromised — the fuel cell’s location under the front seats provides an awkwardly high seating position and the back seat can only seat two people. The Honda Clarity fuel cell vehicle is a more practical, comfortable and generally more normal car. But then there’s the matter of hydrogen as a fuel. Its availability is only widespread enough in California (subsequently the only state you can buy a Mirai), and it takes an awful lot of energy to produce hydrogen, essentially wiping out much of the environmental gains. True, you can refill much quicker than it takes an EV to recharge, but we’re not sure that’s been a major hangup for Tesla and Chevy Bolt owners. So the Mirai may be compelling for certain eco-minded early adopters, but the future? We’ll have to wait and see.

 What’s New for 2017?

The Mirai was all-new last year and there are no updates made to it this year. See the 2017 Toyota Mirai models for sale near you

 What We Like

Emits nothing but water; quick and effortless acceleration; that feeling you’re driving in the future

 What We Don’t

Only available in California; limited hydrogen filling stations; questionable efficiency of hydrogen as a fuel; cramped two-person back seat; odd high-mounted driving position

 How Much?


 Fuel Economy

The Mirai is a hydrogen fuel-cell vehicle. Instead of a gasoline engine or an electric motor, it has a fuel cell that combines hydrogen (H2) and oxygen (O) to create energy with the only byproduct being — as you might recall from Intro to Chemistry — regular old water. That created energy is then sent through an electric motor, aided by a battery pack that is replenished by the fuel cell and regenerative braking (much like a hybrid). The system produces 151 horsepower and 247 lb-ft of torque.

According to Toyota, the Mirai can travel an estimated 312 miles on a tank of hydrogen and then gets the equivalent of 67 miles per gallon. It’s also worth noting that you get three years’ worth of free hydrogen — of course, you’ll need to live in California, and likely near one of the few hundred hydrogen stations in Southern California and the Bay Area.

Another issue is hydrogen itself, which must be extracted from water or natural gas. That takes a lot of energy. So essentially, you’re using electricity to split water into hydrogen and oxygen, then using that same hydrogen to create electricity again. Just putting electricity into an EV’s battery pack is far more efficient, but from a convenience perspective, it’s much quicker (five minutes) to refill with hydrogen than recharge a battery pack.

 Standard Features & Options

The 2017 Toyota Mirai comes only in a single, loaded trim level. Standard equipment includes 17-inch alloy wheels, passive keyless entry with push-button start, automatic LED headlights, automatic high beams, adaptive cruise control, forward-collision warning and automatic braking, lane-departure warning, blind-spot and rear cross-traffic warning systems, power-folding mirrors, front and rear parking sensors, a rearview camera, heated 8-way power front seats, a heated power tilt-and-telescoping steering wheel, SofTex vinyl upholstery, dual-zone automatic climate control, Safety Connect emergency communications, Toyota’s 8-in Entune touchscreen interface, a variety of smartphone apps, Bluetooth, a navigation system and a JBL sound system that includes satellite radio and a USB port.


The Mirai comes with an expansive array of standard safety equipment. Beyond the usual assortment of front airbags, full-length side curtain airbags, stability and traction control and antilock brakes, it goes above and beyond with rear side airbags, lane-departure warning, blind-spot warning, rear cross-traffic warning and a forward-collision warning system with automatic braking. The hydrogen tanks are also designed to withstand serious impacts and automatically handle any potential leak.

 Behind the Wheel

Driving the Mirai doesn’t feel that different from an electric car. When driven at leisurely speeds around town, you get the same quiet acceleration and instant electric torque. Should you need to get up to speed quickly, the fuel cell produces a whining noise not found in EVs, nor the Honda Clarity, but we certainly wouldn’t call it objectionable.

In terms of ride and handling, the Mirai feels solid when cruising down the highway — the result of being quite heavy — but there’s not much feedback through the steering. The Clarity feels like the sharper and more natural car to drive. The Mirai seems more like a luxury Prius.

The same could be said for the interior — there are higher-quality materials, but the general, oddly futuristic design with center-mounted instruments feels familiar. Unfortunately, the driving position is oddly high due to the fuel cell being located below the front seats. You may find you’re uncomfortably close to the roof. The back seat is also pretty cramped and can only seat two people — the Clarity is much bigger and can seat five. The two cars’ trunks are comparable.

 Other Cars to Consider

2017 Honda Clarity — This is the only other hydrogen car you can widely buy, so this one is obvious. In many ways, it’s the superior vehicle simply for being a lot more normal.

2017 Chevrolet Bolt — The Bolt is considerably cheaper, available across the country, better to drive and, although requiring more time to replenish its energy, is inherently more efficient.

Used Tesla Model S — The Tesla is more expensive than the Mirai, but as a used car, you may be able to get one at a comparable price. It’s certainly the more appealing car.

 Autotrader’s Advice

As there’s only one version from which to choose, we guess we can advise getting the nifty Atmospheric Blue Metallic paint? Otherwise, really consider whether going with hydrogen is the smartest choice — logistically, financially and environmentally — then also drive the Clarity to be sure.
