Exploring Land Cruiser's Seven Decades of Innovation: A Discussion with Lead Engineers (Initiate 1)
The Land Cruiser, a name synonymous with rugged reliability and unmatched off-road capabilities, has been a cornerstone of Toyota's vehicle lineup for over seven decades.
The story of the Land Cruiser began in 1951 with the debut of the BJ Series, a vehicle developed in response to a request from the American military and the National Police Reserve. Hanji Umehara, who oversaw the development of the first-generation BJ Series, had a deep faith and love for the car due to its rocky start.
Fast forward to the mid-2010s, and Takami Yokoo took the reins of Land Cruiser development. Yokoo, along with Sadayoshi Koyari, played pivotal roles in chassis design, differential design, torque vectoring system development, and product development. Their dedication to the Land Cruiser is evident in the vehicles they have produced.
The Land Cruiser lineup consists of three models: the Heavy Duty 70 Series, the Station Wagon, and the Light Duty Prado. The 70 Series, known as the workhorse of the Land Cruiser family, is currently in charge of Koyari, who is affectionately known as "Mr. Land Cruiser".
The development of the BJ Series was motivated by the rejection of Mitsubishi's CJ3B Jeep and Toyota's ambition to surpass it. This spirit of competition continues to drive the Land Cruiser team today, as they strive to create vehicles that are not just capable, but inspire trust. As Umehara once said, "a car without (the developer's) confidence will not inspire trust".
Yokoo's "genchi genbutsu" experience involved visiting Australia as part of the 5 Continents Drive Project. This hands-on approach to understanding the vehicle's capabilities has led to the Land Cruisers being tested in some of the harshest environments, from deserts to high-altitude areas.
In Australia, Land Cruisers are used on graded yet unpaved roads, some rutted and others with poor visibility. The Land Cruiser team, led by Yokoo and Koyari, have tested the Land Cruiser 300 Series in these conditions, ensuring that the vehicle is ready to tackle any terrain.
The Land Cruiser 300 Series made its debut on June 10, 2021. Before its release, the team attempted a similar stone steps ascent at Mt. Fudo in Okazaki City, demonstrating the vehicle's incredible off-road capabilities.
The Land Cruiser is also a staple in the Middle East, where it is used for various purposes, from transportation to fishing, and even as police vehicles. Koyari's firsthand experience with the Land Cruiser involved meeting customers in the Middle East, further solidifying his love for the vehicle.
Toyota has produced over 10 million Land Cruisers, making it the third most produced vehicle in Toyota's history, behind only the Corolla and Hilux models. The company's commitment to the Land Cruiser is evident in its latest venture: the "Lunar Cruiser", Toyota's announced lunar rover, named as a counterpart to the terrestrial Land Cruiser.
The original Land Cruiser BJ Series made an ascent of Mt. Fuji in 1950, taking around three hours to reach the fifth station and six hours to climb from the fifth to the sixth station. This feat showcases the Land Cruiser's early off-road prowess and sets the stage for the incredible journey the vehicle has taken since.
From its humble beginnings to its current status as a global icon, the Land Cruiser continues to inspire trust and awe in all who encounter it. Whether navigating the harsh terrain of Australia or the bustling streets of the Middle East, the Land Cruiser stands as a testament to Toyota's commitment to creating vehicles that are not just capable, but unstoppable.
