Using hydrogen fuel cell technology, the Mirai converts hydrogen to electricity, which is then used to power an electric motor. The motor is connected to the front wheels, where it sends its 153 hp to the ground. Like other cars powered by electric motors, the Mirai is extremely torquey, with 247 lb-ft available from a dead stop. While the Mirai isn't fast by most measures, it's powerful enough for the average driver, with all that torque making it feel especially sporty off the line.
The Mirai is smaller than Toyota's midsize Camry, but it's got plenty of upscale features to help justify its premium price point. The front seats are 8-way power adjustable and heated units while the stereo is made by JBL. Navigation is included and is displayed through a large LCD screen housed in the dashboard. A smaller screen sits below, housing the controls for the climate control. Other features include a leather wrapped, heated steering wheel, LED headlamps with an auto high-beam feature, LED fog lamps, dynamic, radar guided cruise control, front and rear parking sensors, touch sensors on the door handles, 17" wheels and heated outside mirrors.
Toyota is taking safety seriously in the Mirai, particularly because of its relatively new and seldom-utilized fuel source. More common safety features such as air bags, traction control, stability control and anti-lock brakes are all present. However, Toyota have gone the extra mile by including a blind-spot monitoring system, a pre-collision system, a lane departure alert and Safety Connect, which will automatically call for help in an emergency. The hydrogen tanks are specially reinforced with carbon-fiber and polymer linings built in a 3-layer structure. The tanks also include leak detection sensors and safety shut off valves, for an extra dose of safety.
