Firstly, we would express our regret and sympathy to whom suffered from the disaster experienced in Tohoku Pacific Ocean Earthquake.

SIM-Drive has developed the Advance Development Model No. 1 for the period between January 19, 2010 and March 31, 2011. We would report that we completed the construction of the vehicle developed under the project. We named the model “SIM-LEI” as its nickname. LEI stands for the initial letters of “Leading Efficiency In-Wheel motor”.

At first, we planned to place the press presentation on March 29, 2011, however, considering those who suffered from the disaster this time, we decided to simply announce the completion of the model by this press release only.

The object of this project is to develop a prototype of the advanced development model aiming to start mass-production in 2013. This project collected 34 establishments and organizations who intend to enter in the electrical vehicle business in the future.

The target performance of SIM-LEI was to achieve over 300km of range per charge, which is generally pointed as the major concern for the electrical vehicle to promote in the market. The prototype achieved this target by 333km of range per charge by JC-08 mode, which represents general urban traffic condition in Japan. The battery capacity to achieve this target is 24.5kWh as almost the same level as other electrical vehicles presented in the market. Alternating Current electrical power consumption rate is 77Wh/km. This is equivalent to 70km/L of the fuel efficiency rate with gasoline as the energy consumption rate.

The fundamental technologies to achieve this performance are the SIM-Drive original technologies, such as in-wheel motor and component built-in frame. Other than these two, the following technologies contribute a lot. All steel monocoque body contributes to reduce body weight. High power density battery provides highly efficient energy re-generation. Super low rolling friction resistance tire reduces friction resistance. The super low air drag body reduced the drag drastically.
