2001 Toyota ES3 Concept

The 2001 Toyota ES3 Concept is an ultra-compact city car designed for efficiency and environmental friendliness. With a length of 3520 mm, it boasts an aluminum body frame covered with plastic panels, contributing to its lightweight nature of about 700 kg. The ES3 is powered by a 1.4-liter common rail turbodiesel engine coupled with a continuously variable transmission (CVT). The narrow 145/70R15 tires are designed for low rolling resistance, contributing to an outstanding fuel consumption of only 2.7 liters per hundred kilometers.


The ES3, also known as Eco Spirit Cubic, is a four-seater vehicle incorporating Toyota's innovative environmental technologies. It emphasizes low emissions, easy recycling, and remarkable fuel efficiency, exceeding 100 miles per gallon. The key to this exceptional fuel economy lies in the combination of a highly efficient engine and a lightweight aerodynamic body.


The engine is a 1.4-liter common-rail direct injection turbocharged powerplant, mated to a newly developed CVT. The transmission features a torque converter equipped with a lock-up torsional damper, contributing to class-leading fuel efficiency. The ES3 incorporates a Stop and Go powertrain management system that shuts off the engine when the vehicle is stationary and instantly restarts upon acceleration.


In addition, the ES3 employs a regenerative braking system, converting deceleration energy into electric energy stored in a capacitor. This stored energy powers auxiliary electric loads and engine restarts, reducing overall fuel consumption.


To achieve a curb weight of only 700 kg, the ES3 utilizes a robust yet lightweight aluminum body with plastic outer panels. The interior components are intelligently designed for weight reduction, featuring magnesium alloy for front seat frames and reduced seat cushion weight.


Toyota has placed a strong emphasis on recycling in the development of the ES3, using materials with excellent recyclability. Super Olefin Polymer, for instance, is employed in the bumpers and outer panels.


The 2001 Toyota ES3 Concept represents Toyota's commitment to developing practical and intelligent solutions for reducing global emissions. It made its debut at the 2001 Frankfurt Motor Show and showcases Toyota's dedication to environmentally conscious vehicle development.
