Inmotive Introduces World's Most Efficient Two-Speed Transmission for Electric Vehicles
TORONTO, Sept. 24, 2020 /PRNewswire-AsiaNet/ --

- Delivers extensive cost savings and extends EV range by up to 15%

- Expertly designed for the next generation of electric vehicles

- Features scalable design for wide range of vehicle applications

Inmotive, a Canadian-based automotive supplier, has launched its patented 
Ingear(TM) two-speed transmission( 
). Invented and designed for the next generation of electric vehicles, the 
Ingear features a simple and durable design that enables a more efficient 
powertrain, with extended range, at lower cost.

Inmotive recently completed its extensive pre-production testing of the Ingear, 
has integrated it into a demonstration vehicle and is ready for full market 
implementation. Test units are available to qualified OEMs. 

"This next-generation transmission offers an entirely new way of looking at 
multi-speed transmissions for electric vehicles and extends significant 
benefits to a wide range of other market segments as well," said Paul Bottero, 
CEO, Inmotive. "It is the first two-speed transmission of its kind to be 
effectively ready for global market adoption."

How it works

Currently, most EVs use single-speed transmissions, however, equipping an EV 
with an Ingear transmission lowers cost, extends range and improves 
acceleration times, highway passing capability, top-speed and gradeability. 

Typically, there are two reduction gears between the electric motor and the 
wheels, with the motor turning about nine times for each revolution of the 
wheels. The Ingear replaces the second reduction gear with a continuous chain 
drive and a morphing sprocket. To shift, an actuator directs sprocket segments 
into place during a single revolution of the wheels, effectively increasing or 
decreasing the gear ratio. The Ingear's patented geometry keeps the motor and 
wheels in sync, enabling continuous torque flow throughout the shift process( 

By enabling the drivetrain to operate more efficiently with low and high-gear 
ability, less energy is wasted resulting in more range from each charge. 
Similarly, regeneration is improved and is continuous, even while downshifting. 

"We've found that today's automatic transmissions fall short of what the EV 
industry needs," said Bottero. "With an efficient design and substantial cost 
savings to the OEM, we believe the Ingear transmission checks all of the boxes 
that OEMs have been looking for and will help support wide-spread adoption of 

Delivering ultimate performance

Key benefits of the new Ingear transmission include:

     - Cost Saving – By integrating the simple and low-component-count Ingear
       into high volume integrated drive units, OEMs can save more than $1,500
       per passenger vehicle. This savings is possible through using less
       battery and less expensive electric motors and inverters all while
       maintaining the same range and improving acceleration. In addition to
       OEM savings, fleet owners will save about $2,000 in operating
       (electricity) costs over three years. 
     - Compact – Designed to wrap around the differential, the Ingear is only
       slightly larger than a typical single speed transmission. 
     - Quick, smooth and quiet – The Ingear shifts in less than a single
       revolution of the wheels. The motor is kept in constant contact with the
       wheels and can continuously apply torque even during the shift. Gear
       ratios change gradually and torque fill algorithms maintain a smooth
       passenger experience. Acceleration times can be improved by up to 15%. 
     - Efficient and reliable – The Ingear extends the range of a typical
       vehicle by up to 15% by optimizing motor efficiency and reducing
       parasitic losses. It also improves towing, hill-climbing and top-speed.

Technology adoption

Ingear is not a "one size fits all" technology. Its design flexibility enables 
OEMs to customize the size and scale of the technology based on the specific 
vehicle type. While initial development has focused on the passenger car 
market, the technology can be adapted for a wide range of vehicles, including 
commercial, off-highway and fuel cell applications. 

Inmotive currently has development contracts with two global OEMs and is in 
discussion with several other OEMs from around the world for implementation.
