2001 I.DE.A KAZ

The I.DE.A KAZ (Keio Advanced Zero-Emission Vehicle) is an electric-powered prototype developed collaboratively by the I.DE.A Institute and Keio University in Japan, showcased at the Geneva Motor Show in 2001. This high-performance and highly functional vehicle is designed to outperform conventional Internal Combustion Engine (ICE) Multi-Purpose Vehicles (MPVs) through the incorporation of innovative component technologies and system advancements.

Unlike conventional ICE MPVs, the I.DE.A KAZ was designed from the ground up, allowing for a flexible body design tailored to its unique features. The vehicle incorporates three groundbreaking component technologies:

  1. Lithium-ion Battery: The Lithium-ion battery plays a crucial role in supplying high energy and power to the KAZ, contributing to its performance and efficiency.

  2. Intelligent Power Module (IPM): The IPM is instrumental in creating inverters with low energy loss and compact size, enhancing the overall efficiency of the vehicle's power management system.

  3. Motors with Nd-Fe Rare Earth Magnets: The motors are designed with Nd-Fe Rare Earth magnets, ensuring high efficiency, substantial torque, and high-speed capabilities, all within a compact size.

The KAZ exhibits a modern interpretation of an MPV in its appearance, reflecting the design expertise of the I.DE.A Institute. Notably, this prototype was developed and built by the institute. The vehicle's innovative features make it stand out in the realm of electric-powered MPVs.

The KAZ is a multi-seat minivan, with the name KAZ standing for Keio Advanced Zero-emission vehicle. The vehicle is an eight-seater and features eight wheels, with steerable wheels on the first, second, and fourth axles. The suspension system is hydropneumatic, providing enhanced ride comfort. Each wheel is equipped with an individual 55-kilowatt electric motor powered by lithium-ion batteries. The total power output of the vehicle is an impressive 440 kW (590 hp), and it boasts a power reserve of up to 300 km. Despite its three-ton weight, the KAZ can reach a maximum speed of 300 km/h, showcasing its remarkable performance capabilities.

In summary, the I.DE.A KAZ represents a pioneering venture into electric-powered MPVs, demonstrating advanced technologies and design concepts that contribute to its high performance, efficiency, and distinctive appearance.
