What Sim-Drive does

Sim-Drive Corporation (株式会社SIM-Drive) was a Tokyo-based electric vehicle technology firm founded in August 2009 as a Keio University venture led by Professor Hiroshi Shimizu. The company developed proprietary in-wheel motor systems, a component-built-in frame platform that mounts critical powertrain components inside the wheels and within a hollow underbody frame, on-board direct-drive technology for EV conversion, and a four-wheel independent torque vectoring control system. Its customers were primarily Japanese and global automotive manufacturers, parts suppliers, and local governments seeking collaborative EV development rather than finished vehicles.

The company's primary output over eight years was a sequence of four prototype vehicles (SIM-LEI, SIM-WIL, SIM-CEL, SIM-HAL) demonstrating improving range (up to 351 km per charge) and acceleration (as low as 0-100 km/h in 4.2 seconds), plus EV conversion packages including a vintage Mercedes-Benz 280SL Electric, a Toyota 86-based SIM-86e AWD conversion, and a Citroën DS3 Electrum FWD conversion.

SIM-Drive monetized through an open-source collaborative development model in which participating organizations paid a 20 million yen participation fee per Advanced Development Project cycle, component sales (notably UFX motors for EV conversion), and technology licensing under the "by SIM-Drive" / "Platform by SIM-Drive" marks. A 50/50 joint venture (stEVe Inc.) with Tokyo R&D Co., Ltd. was established in 2011 to commercialize converted EVs separately. Stated capital was 99 million yen and headcount ranged from 11 to 50 employees. The company ceased operations on June 26, 2017, and its technology and mission were transferred to TAJIMA EV Corporation.

Revenue model

1. Technology Licensing and Component Sales: SIM-Drive provides its in-wheel motor technology and components to companies for EV development and manufacturing. Companies using certified components receive 'by SIM-Drive' or 'Platform by SIM-Drive' licensing.
2. Advanced Development Project Participation Fees: Each participating organization pays 20 million yen participation fee for joint prototype development projects. This covers approximately one year of collaborative prototype development with the aim of mass production around 2014.
3. EV Conversion Components: Manufacturing and sales of UFX motors and other electrical components for EV conversion. Standardization of conversion parts and provision for repairs and maintenance.

Core offering

SIM-Drive developed proprietary electric vehicle technology centered on in-wheel motors and a component built-in frame platform, conducting Advanced Development Projects where partner organizations paid 20 million yen per project to co-develop prototype EVs. The company licensed its technology and brand ("by SIM-Drive" / "Platform by SIM-Drive") to manufacturers and supplied components such as UFX motors for EV conversion and production. It also produced demonstration prototype vehicles (SIM-LEI, SIM-WIL, SIM-CEL, SIM-HAL) and EV conversion showcases (DS3 Electrum, SIM-86e, 280SL Electric) to validate and commercialize its technology.

Product overview

SIM-Drive offers a portfolio of electric vehicle technologies and prototype vehicles centered on in-wheel motor systems. The core product line includes in-wheel motors, Platform by SIM-Drive (component built-in frame), On-board Direct Drive systems, and Four-wheel Independent Control technology. The company developed four generations of prototype electric vehicles (SIM-LEI, SIM-WIL, SIM-CEL, SIM-HAL) demonstrating increasing performance capabilities from 268km to 351km+ range. Additionally, SIM-Drive commercializes EV conversion solutions including the 280SL Electric vintage car conversion, SIM-86e 4WD conversion, and DS3 Electrum 2WD conversion. A joint venture stEVe Inc. handles converted EV development and manufacturing. The company ceased operations on June 26, 2017, with technologies transferred to TAJIMA Motor Corporation.

Others

• Tajima Motor Corporation: Tajima Motor Corporation was a founding investor of SIM-Drive and ultimately absorbed its technology into its Next-Generation Mobility Division (TAJIMA EV Corporation) following the 2017 dissolution. Closely connected through technology transfer and leadership (Nobuhiro Tajima served as SIM-Drive President).
• Mitsubishi Motors: Mitsubishi Motors was a participating organization in SIM-Drive's Advanced Development Projects (2011-2012). As a major Japanese automaker with EV heritage (i-MiEV), represents the type of OEM customer/partner SIM-Drive's open-source platform was designed to serve.

Direct peers

• e-Traction: e-Traction (Netherlands, now part of Evergrande NEV) developed in-wheel motor technology for commercial vehicles and buses. Directly comparable in-wheel motor technology focus, with emphasis on fleet electrification applications overlapping with SIM-Drive's conversion and EV platform work.
• Elaphe Propulsion Technologies: Elaphe is a Slovenia-based company specializing in in-wheel motor propulsion systems for electric vehicles. Closely comparable to SIM-Drive's in-wheel motor technology with similar focus on direct-drive wheel-mounted motors and OEM/retrofit applications.
• Protean Electric: Protean Electric is a UK-based pioneer in in-wheel electric motor technology for passenger and commercial vehicles. Most directly comparable peer—same core technology (in-wheel motors), similar target market (EV OEMs and conversion applications), and similar business model of licensing the technology to vehicle manufacturers.
• REE Automotive: REE Automotive (Israel) developed an EV platform architecture using corner motors and modular chassis design. Closely aligned with SIM-Drive's Platform by SIM-Drive approach, both pursuing integrated chassis platforms with distributed electric drive.

Broad incumbents

• Aisin Corporation: Aisin is a major Japanese automotive parts manufacturer with significant EV powertrain and electrified drivetrain offerings. Comparable as a Japanese automotive supplier with EV technology capabilities, though operating at much larger scale across multiple component categories.
• Bosch eMobility: Bosch is a global automotive supplier with comprehensive EV powertrain offerings including e-axles, motors, and power electronics. Overlapping capability in EV motor and powertrain technology, but vastly broader portfolio and global manufacturing footprint.
• Nidec Corporation: Nidec is a Japanese global motor manufacturer that has expanded aggressively into EV traction motors, including E-Axle systems. Comparable as a Japanese motor manufacturer serving EV OEMs, though broader in scope and vastly larger in scale than SIM-Drive.
