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

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!

Tesla is reportedly testing Apple’s CarPlay software for its vehicles, marking a major shift after years of resisting the tech giant’s ecosystem.

Citing insiders reportedly familiar with the matter, Bloomberg News claimed that CarPlay is being trialed by the EV maker internally. The move could help Tesla gain more market share, as surveys have shown many buyers consider CarPlay as an essential feature when choosing a car.

Not the usual CarPlay experience

Bloomberg claimed that Tesla’s tests involve a rather unique way to integrate CarPlay. Instead of replacing the vehicle’s entire infotainment display, Tesla’s integration will reportedly feature a CarPlay window on the infotainment system. This limited approach will ensure that Tesla’s own software, such as Full Self-Driving’s visuals, remains dominant.

The feature is expected to support wireless connectivity as well, bringing Tesla in line with other luxury automakers that already offer CarPlay. While plans remain fluid and may change before public release, the publication’s sources claimed that the rollout could happen within months.

A change of heart

Tesla has been reluctant to grant Apple access to its in-car systems, partly due to Elon Musk’s past criticism of the tech giant’s App Store policies and its poaching of Tesla engineers during the failed Apple Car project. Tesla’s in-house software is also deemed by numerous owners as a superior option to CarPlay, thanks to its sleek design and rich feature set.

With Apple’s retreat from building cars and Elon Musk’s relationship with Apple for X and Grok, however, the CEO’s stance on the tech giant seems to be improving. Overall, Tesla’s potential CarPlay integration would likely be appreciated by owners, as a McKinsey & Co. survey last year found that roughly one-third of buyers considered the lack of such systems a deal-breaker.

China considering EV acceleration limits to curb high-speed accidents

If approved, the regulation would be a national standard.

Recent reports have emerged stating that China is considering new national standards that would restrict how fast electric vehicles can accelerate upon each startup. The potential regulation is reportedly being considered amidst a rise in EV-related crashes.

The draft for the proposed regulation was released by the Ministry of Public Security on November 10. If approved, the regulation would be a national standard.

New regulation targets default performance limits

Under the proposal, all passenger vehicles would start in a state where acceleration from 0–100 km/h (0-60 mph) would take no less than five seconds. This rule would apply to both pure EVs and plug-in hybrids, and it is aimed at preventing unintended acceleration caused by driver inexperience or surprise torque delivery.

The public has until January 10, 2026, to submit feedback before the rule is finalized, as noted in a CNEV Post report.

Authorities have stated that the change reflects growing safety concerns amidst the arrival of more powerful electric cars. The new regulation would make it mandatory for drivers to deliberately engage performance modes, ensuring they are aware and ready for their vehicles’ increased power output before accelerating.

A rise in accidents

China’s EV sector has seen an explosion of high-powered models, some capable of 0–100 km/h acceleration in under two seconds. These speeds were once reserved for supercars, but some electric cars such as the Xiaomi SU7 Ultra offer such performance at an affordable cost.

However, authorities have observed that this performance has led to an uptick in accidents. I recent years, incidents of crashes involving lack of control in vehicles with rapid acceleration have risen, as per an explanatory note accompanying the draft.

Part of this is due to drivers seemingly being unprepared for the power of their own vehicles. For context, driving schools in China typically use cars that accelerate to 100 km/h in more than 5 seconds. This level of acceleration is also typical in combustion-powered cars.

Tesla has once again claimed the top spot in the UK’s most anticipated EV charging satisfaction survey. As per Zapmap’s 2025 driver satisfaction rankings, the Tesla Supercharger network was voted Best Large EV Charging Network for the second consecutive year.

The annual survey, based on thousands of EV driver responses, measures reliability, ease of use, and payment experience across the UK’s public charging landscape.

Tesla tops the survey’s “Large” category

Zapmap’s 2025 rankings, which were drawn from nearly 4,000 battery electric vehicle (BEV) drivers, reflect how quickly public charging is evolving across the UK. For the survey’s “Large” network class, which includes systems with over 500 devices, Tesla once again stood out for reliability and cost efficiency.

The automaker now offers 1,115 open Supercharger devices at 97 public sites, roughly 54% of its total UK network. That’s a 40% increase in public availability compared to September 2024. A particularly appreciated aspect of the Supercharger network is its cost, which continues to be “significantly lower prices than most rapid/ultra-rapid networks, with drivers also appreciating its reliability,” Zapmap noted.

Thanks to everyone who voted, two years in a row! https://t.co/rPPMbQdC2m— Tesla UK (@tesla_uk) November 13, 2025

Tesla Regional Manager’s comments

Ollie Dodd, Senior Regional Manager for Northern Europe Charging at Tesla, shared his appreciation for the Supercharger network’s award.

“We’re thrilled to win Zapmap’s Best EV Charging Network for the second year in a row. Being recognized by the drivers themselves shows that our customer-centric and data-driven approach to building sites is well-received. We look forward to showcasing more customer-centric features in 2026 as we expand the network further and look towards new initiatives in roaming and payment methods,” he said.

Conducted during September and October 2025, Zapmap’s eighth annual survey found that reliability and payment flexibility remain top priorities among EV drivers, two things that the Supercharger network particularly excels in. Fortunately for UK EV owners, the Supercharger network is also aggressively growing.
