Tesla Model S vs. Toyota Mirai Comparison

Published

on

With the introduction of the new hydrogen-powered Toyota Mirai (the name means “future” in Japanese), there has been a lot of media hype about vehicles that use hydrogen fuel cells as their power source. Toyota, Honda and a number of other automobile companies have announced plans to build cars based on fuel cell technology.

Fundamentally, a hydrogen fuel cell produces electricity via an electro-chemical reaction that drives an electric motor that creates the motive force for a car. The technology requires high-pressure storage of liquid hydrogen, a fuel cell to convert the H2 to electrons, a control system to deliver the resultant electricity to an electric motor and/or battery that in turn drives the wheels of the vehicle. It’s a workable, if somewhat complex system that produces zero emissions and water as a by-product.

In the media, there are three major claims that are being made about cars powered by hydrogen: (1) that H2 is a 21st century energy source and will ultimately become the preferred power source for automobiles; (2) that hydrogen-powered fuel cells represent a significant improvement in environmentally safe automotive fuel, and (3) that cars like the Toyota Mirai represent a major threat to battery electric vehicles (BEVs) like the Tesla Model S.

Are any or all of these claims true? We thought we’d take a look.

After going through the popular literature and government/academic reports, we decided that the best way to present the array of information collected was with an infographic, “Tesla Model S vs. Toyota Mirai: A Technology/Vehicle Comparison,” that examines four broad categories of concern:

  • underlying technology that powers the vehicle
  • the two vehicles themselves
  • technology required for refueling the vehicle, and
  • environmental impact

Tesla Model S vs. Toyota Mirai

Tesla Model S vs. Toyota Mirai Infographic

Technology

EV technology has been around for 100 years. It represents a remarkably simple method for automotive power that is constrained solely by the capacity of the vehicle’s batteries. Fuel cells are evolving rapidly and provide more energy capacity than modern Li-Ion batteries, but they require liquid hydrogen to be stored on board the vehicle in pressurized tanks. The Tesla Model S has an energy capacity of either 60 kWh or 85 kWh while the Toyota Mirai produces 114 kWh. The overall energy efficiency (from an environmental viewpoint) of BEVs is dependent on the efficiency of the electric grid from which a BEV obtains its diet of electrons. The efficiency of hydrogen-powered cars is impacted by the process that extracts hydrogen from other sources and the method by which hydrogen is transported to a refueling station.

The winner: It’s close, but the simplicity of the BEV system gives the underlying technology of the Model S a slight edge.

The Vehicles

Both the Tesla Model S and the Toyota Mirai are expensive, but that’s the price of new technology. The Model S is a premium, high performance automobile in ever sense of the word. It is a visually beautiful car that conjures images of a Aston Martin or Jaguar and has been lauded as one of the best sedans in the world. It has won praise from virtually every automotive media source, and is one of the safest, roomiest cars on the planet. The Toyota Mirai has an eccentric look that gives it a boxy Prius-like feel. It appears to provide good, basic transportation, but it is not for those who want a bit more than good, basic transportation. Finally, the Tesla Model S is here today. By 2017, there will be about 160,000 Model S vehicles on the road. Toyota projects that only 3,000 Mirais will be in the field by the same date.

The winner: No contest! The Model S is far superior to the Mirai in virtually every respect except for range.

Fueling the Vehicle

In our view, one of the major benefits of BEVs is that you refuel them at home, overnight, while you’re sleeping, so that your Model S is “full” every morning. Unless you travel long distances on a regular basis, you will rarely need a Tesla Supercharger or any other refueling source away from home. That’s huge, and often get’s lost in the discussion of “range anxiety” that always seems to invade the thinking of those who don’t own a Model S. Although fuel cells are sexy, it seems odd to us that Toyota has returned to a 20th century fueling station paradigm. In essence, there is little difference between refueling a Mirai and refueling a Camry. Sure, the fuel is different, but you have to hunt for a specific refueling station as your Mirai slowly depletes its hydrogen. No charging at home—ever.

The winner: No contest! Refueling your vehicle at home is a convenience that represents 21st century thinking. Model S provides that convenience. Mirai does not.

Environmental Impact

Both the Model S and the Mirai are environmentally impressive. Both have zero emissions and relatively low “well-to-wheel” inefficiencies. In our view, the beauty of a BEV is that it becomes increasingly friendly to the environment as our electric grid infrastructure improves. There is no need to separately transport fuel to a refueling station (a requirement for a hydrogen fuel cell vehicle) eliminating both the cost and the environmental impact of secondary fuel transport.

The winner: It’s a toss up. Both cars are environmentally friendly and both will improve as the grid becomes cleaner and as hydrogen extraction processes become more efficient and cost effective.

As a young engineering student I was taught that when you consider alternative systems that both achieve the same result, always choose the less complex approach. That’s common sense, but it appears that when faced with the same choice, Toyota chose the more complex option. Possibly, their engineers or marketing people were driven by concern about range, but that’s simply not as big an issue as they think it is. BEVs represent simplicity, and in an increasingly complex world, that’s something that many consumers like.

Is the Mirai (or another similar H2 vehicle) a “Tesla Killer”? Not a chance!

Elon Musk shares unbelievable Starship Flight 10 landing feat

Flight 10’s Starship upper stage demonstrated impressive accuracy when it came to its target landing zone.

SpaceX CEO Elon Musk recently shared an insane feat accomplished by Starship’s upper stage during its tenth test flight.

Despite the challenges it faced during its return trip to Earth, Flight 10’s Starship upper stage demonstrated impressive accuracy when it came to its target landing zone.

Against the odds

Musk’s update was shared on social media platform X. In a conversation about Starship upper stage’s return to Earth, Musk revealed that the upper stage splashed down just 3 meters (under 10 feet) from its intended target. Considering the size of the Starship upper stage and the ocean itself, achieving this accuracy was nothing short of insane.

Starship Flight 10 was a success as both the Super Heavy booster and Ship upper stage completed all their mission objectives. However, videos and images released by SpaceX showed the upper stage’s heat shield scorched golden-brown and parts of its aft skirt visibly missing. The flaps and other surfaces also bore signs of heavy stress from reentry.

SpaceX highlighted this in a post on X: “Starship made it through reentry with intentionally missing tiles, completed maneuvers to intentionally stress its flaps, had visible damage to its aft skirt and flaps, and still executed a flip and landing burn that placed it approximately 3 meters from its targeted splashdown point,” SpaceX noted.

A key milestone

The result stands in stark contrast to Starship’s earlier test flights this year, when all three prior upper-stage flights in 2025 ended in premature breakup before splashdown. Flight 10 not only marked the first successful splashdown of the year for the Starship upper stage, but it also delivered near-perfect precision despite its battered state, according to a Space.com report.

For SpaceX, this success is a critical proof point in developing a fully reusable launch system. A spacecraft capable of surviving severe reentry conditions and still landing within meters of its target underscores the robustness needed for future missions, including orbital payload deliveries and, eventually, landings on the Moon and Mars.

It took some time, but the new Tesla Model Y Performance is finally here. The new Model Y Performance features a blend of aerodynamic improvements, upgraded interior comforts, and high range enabled by new battery cells. 

The updated Model Y Performance is produced at Gigafactory Berlin and is available to order now in Europe and the Middle East. First deliveries are expected in 1-2 months.

Key Model Y Improvements

The new Model Y Performance sharpens the vehicle’s design and driving dynamics while adding subtle interior refinements. The revised variant now delivers 0–60 mph in 3.3 seconds, slightly quicker than its predecessor’s 3.5 seconds, while offering an EPA-estimated 308 miles of range, just about 1% less than the non-performance Dual Motor All Wheel Drive variant. Top speed is listed at 155 mph.

The exterior of the new Model Y Performance features new front and rear fascias, along with a carbon fiber spoiler designed for greater downforce and reduced drag. Staggered wheels and tires provide improved steering precision and grip, while high-performance brakes offer enhanced pedal feel and better heat management. The ride is supported by adaptive suspension that adjusts damping based on road conditions, paired with unique drive modes tailored for high-speed performance. Ground clearance is listed at 6.1 inches, and weight is listed at 2,033 kilograms (4,482 pounds).

Tech and Interior

Inside, Tesla has added carbon fiber decor, expanded ambient lighting in the footwells and door pockets, and upgraded seating. The first-row sport seats now include power recline, power tilt, heating, ventilation, and powered thigh extensions for added support during cornering. Rear passengers receive perforated heated seats with power recline. A new 16-inch QHD center touchscreen anchors the cabin’s technology suite.

Elon Musk reveals when SpaceX will perform first-ever Starship catch

“Starship catch is probably flight 13 to 15, depending on how well V3 flights go,” Musk said.

Elon Musk revealed when SpaceX would perform the first-ever catch attempt of Starship, its massive rocket that will one day take life to other planets.

On Tuesday, Starship aced its tenth test flight as SpaceX was able to complete each of its mission objectives, including a splashdown of the Super Heavy Booster in the Gulf, the deployment of eight Starlink simulators, and another splashdown of the ship in the Indian Ocean.

It was the first launch that featured a payload deployment:

SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative

SpaceX was transparent that it would not attempt to catch the Super Heavy Booster, something it has done on three previous occasions: Flight 5 on October 13, 2024, Flight 7 on January 16, and Flight 8 on March 6.

This time, it was not attempting to do so. However, there are bigger plans for the future, and Musk detailed them in a recent post on X, where he discussed SpaceX’s plans to catch Starship, which would be a monumental accomplishment.

Musk said the most likely opportunities for SpaceX to catch Starship itself would be Flight 13, Flight 14, and Flight 15, but it depends on “how well the V3 flights go.”

The Starship launched with Flight 10 was a V2, which is the same size as the subsequent V3 rocket but has a smaller payload-to-orbit rating and is less powerful in terms of initial thrust and booster thrust. Musk said there is only one more V2 rocket left to launch.

V3 will be the version flown through 2026, as V4, which will be the most capable Starship build SpaceX manufactures, is likely to be the first company ship to carry humans to space.

Musk said that SpaceX planned to “hopefully” attempt a catch of Starship in 2025. However, it appears that this will likely be pushed back to 2026 due to timing.

SpaceX will take Starship catch one step further very soon, Elon Musk confirms

SpaceX would need to launch the 11th and 12th test flights by the end of the year in order to get to Musk’s expected first catch attempt of Flight 13. It’s not unheard of, but the company will need to accelerate its launch rate as it has only had three test flights this year.
