Summary Reader Response Draft #3 (Toyota Mirai)

 In 2014, the very first Toyota Mirai, a mid-size hydrogen fuel cell vehicle was introduced by Toyota. According to Leow (2022), the Mirai, which means “future” in Japanese, is a hydrogen fuel-cell car that boasts a unique engine that distinguishes itself from its market rivals. The Mirai uses a hydrogen fuel-cell stack to power itself, unlike conventional batteries. According to Hunting (2023), external oxygen mixes with the hydrogen stored to generate electrical energy, which powers the electric motors. Water is the only waste product due to the mixture, causing zero emissions. Based on the Mirai webpage by Toyota itself, (Toyota, n.d.), the Mirai’s hydrogen engine allows a rapid refuelling time of five minutes. In 2019, the second generation Mirai is introduced, it boasts many improvements compared to the model before. For starters, the ride is quieter and smoother. Its new engine also provides more power and is lighter, allowing the Mirai to hit 100km/h with much ease. Some additional performance figures and features of the Mirai include a 645-kilometer range on one tank, and three different driving modes depending on the driver’s utilization of the vehicle, (Eco, Normal and Sport). To add on, Toyota, remarkably, achieved these improvements to the engine with parts that cost two-thirds of the engine before (Leow, 2022).

 

“The more you drive, the more you clean the air”, (Halvorson, 2021). With its advanced technology, the Mirai is the vanguard of using hydrogen in transportation, which implies cleaner transportation in the future and benefits the environment. 

 

According to Halvorson (2022), The Mirai not only produces zero emissions but is also able to filter out chemical pollutants (sulphur dioxide, nitrogen dioxide, and ammonia), and pollutants that are invisible to the naked eye (pollens, dust etc.) through the two-step PM2.5 particular filter. At the first stage of the purification, the catalyst filter can trap and neutralize chemical pollutants. The electrostatically charged paper in the second can trap invisible pollutants. In a test drive, a 2200-kilometre (km) drive can clean up nearly 1500kL (kilolitres) of air. 

 

The Mirai, according to Euro NCAP (2021), received a five-star safety rating. It features Toyota Safety Sense™ 2.5+ technology, including a pre-collision system with pedestrian detection (PCS w/PD), dynamic radar cruise control (DRCC), lane departure alert with steering assist (LDA w/SA), land tracing assist (LTA), road sign assist (RSA), and automatic high beam (AHB) (Toyota, n.d.). The PCS w/PD can detect pedestrians, cyclists, and vehicles, issuing warnings and applying emergency braking if necessary. DRCC maintains a safe distance from vehicles ahead, while LDA w/SA warns of lane departures and adjusts steering to keep the car in its lane. LTA helps centre the car in the lane, RSA displays traffic signs on the multi-information display (MID), and AHB automatically switches between high and low beams based on surrounding brightness and other vehicles' lights. Additionally, the Mirai's body structure is designed to absorb and disperse collision forces, making it a safe choice that meets global safety standards.

 

Despite Mirai’s advanced technologies and safeness, there are still challenges making it accessible all around the world. The Mirai is now only available in the United Kingdom, United States, Denmark, Germany, Belgium, Norway, and Japan. The main challenge is the lack of hydrogen fuelling centres (HFCs), there are only about 1000 HFCs around the world. China, Japan, and Korea are the top three countries with HFCs, and Germany is the only European country which has over 100 HFCs available (Information Trends, n.d.). Besides, there are still competing manufacturers with hydrogen fuel-cell cars, with such high demands for HFCs, the market of Toyota Mirai is still immature and unavailable in most countries. The difficulties of setting up a HFC are also a major factor, as hydrogen gas is a highly flammable gas. It is harder to be compressed and can be costly. According to Hydrogen Central (2023), to construct a HFC in California, the cost is estimated around 1.5 to 2 million US Dollars. 

In conclusion, hydrogen fuel-cell cars like the Toyota Mirai can represent a great step toward a greener and cleaner future. The challenges faced by infrastructure limitations and production costs; these will take a huge hurdle to overcome. With advancements in technologies nowadays, Toyota Mirai is giving hope and paths toward a more sustainable transportation.
