Compare the2024 Toyota MiraiVS 2024 Porsche Taycan

The Mirai has standard Whiplash Injury Lessening Seats (WIL), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the WIL system moves the headrests forward to prevent neck and spine injuries. The Taycan doesn’t offer a whiplash protection system.

The Mirai has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Taycan doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Mirai offers an optional Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Taycan doesn’t offer backup collision prevention brakes.

The Mirai has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Taycan’s blind spot costs extra.

To help make backing out of a parking space safer, the Mirai’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engages the brakes to help avoid a collision. The Taycan doesn’t offer a rear cross-path warning system.

The Mirai’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Taycan doesn’t offer a driver alert monitor.

Both the Mirai and the Taycan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.

Toyota’s powertrain warranty covers the Mirai 1 year and 10,000 miles longer than Porsche covers the Taycan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Taycan ends after only 4 years or 50,000 miles.

Toyota pays for scheduled maintenance on the Mirai for 1 year and 11000 miles longer than Porsche pays for maintenance for the Taycan (3/35000 vs. 2/24,000).

There are over 6 times as many Toyota dealers as there are Porsche dealers, which makes it much easier should you ever need service under the Mirai’s warranty.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Toyota vehicles are more reliable than Porsche vehicles. J.D. Power ranks Toyota above average in long-term dependability. With 34 more problems per 100 vehicles in the first three years of ownership, Porsche is rated lower.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Toyota vehicles are more reliable than Porsche vehicles. Consumer Reports ranks Toyota second in overall reliability. Porsche is ranked 8th.

The Mirai can travel longer on a full tank of hydrogen than the Taycan Sedan on a full charge:

For better traction, the Mirai has larger standard tires than the Taycan (235/55R19 vs. 225/55R19).

The Toyota Mirai may be more efficient, handle and accelerate better because it weighs about 300 to 850 pounds less than the Porsche Taycan.

For excellent aerodynamics, the Mirai has standard flush composite headlights. The Taycan has recessed headlights that spoil its aerodynamic shape and create extra drag.

The Mirai has .2 inches more front headroom, .4 inches more front legroom, 2 inches more front shoulder room, .9 inches more rear legroom and 1.2 inches more rear shoulder room than the Taycan.

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The Taycan’s non-lockable folding seat and non-lockable remote release defeat cargo security.

If the windows are left open on the Mirai the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the Taycan can only operate the windows from inside the vehicle, with the ignition on.

The Mirai’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Taycan’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Mirai has standard extendable sun visors. The Taycan doesn’t offer extendable visors.

A power rear sunshade and manual rear side window sunshades are standard in the Mirai Limited to help block heat and glare for the rear passengers. The Taycan doesn’t offer a rear or rear side window sunshades.

Standard air conditioned seats in the front and rear seats keep the Mirai Limited’s passengers comfortable and take the sting out of hot leather in summer. The Taycan doesn’t offer air-conditioned seats in the rear.

The Mirai Limited offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Taycan doesn’t offer a house-current electrical outlet.
