The Route Powertrain

The Route Truck

A Range-Extending Generator

  • Decoupled loads: generator works to charge batteries, while batteries provide power to turn the wheels.
  • Open generator architecture: the Wrightspeed Route ™ can use any number of on-board power generation options, including micro-turbines and piston engines.
  • No range anxiety! The Route ™, given refueling, has an unlimited range.

B High-Power Battery System

  • Exceptional regen capability: 400 hp
  • The high-power battery system provides peak power, allowing the generator to operate at its most efficient point.
  • PLUG IT IN, for up to 40 miles on grid energy.

C Extended Battery Life

  • Actively cooled for long battery life.
  • Software protected for long battery life.

D The Geared Traction Drive (GTD)

  • Integrates an electric motor, a two-speed gear box & an inverter
  • Two per driveaxle
  • Compact, lightweight
  • Direct traction control at drivewheels
  • 125-250 horsepower, continuous
  • 18,000 ft-lbs total axle torque
  • 75 mph max speed (limited)
  • 400 hp regen braking power, with slip limiting

E Fuel Tank

  • The Wrightspeed Route can be custom fitted to run diesel, gasoline, biofuels, CNG, or landfill gas at up to 7% sulfides.

Torque / Power for The Route


Fuel Management

  • The Route provides impressive improvements in fuel economy: depending on drive cycles, fuel use can drop 50% or more.
  • The Wrightspeed Route allows a significant part of daily mileage to be driven on inexpensive grid energy, with onboard power generation for unlimited range.
  • Unlike many hybrid systems, the Route generator engine operates at its peak efficiency, charging the batteries as needed, and the electric motors always power the wheels.

Asset Management

  • Because the Wrightspeed Route is a retrofit system, it presents great advantages in reducing a vehicle’s Total-Cost-to-Operate.
  • Replacing traditional powertrains with the simple Wrightspeed Route limits unit down time and greatly reduces overall maintenance costs.
  • The Wrightspeed advanced Vehicle Management System (VMS) allows for easy fleet information management and is built for compatibility with Fleet Information Management software.
  • The Vehicle Dynamics Control System provides silky smooth power delivery. It also provides perfect traction control under severe road conditions, limiting fleet events.

High Power

  • The Route is extremely high-power.
  • 400 hp regenerative braking
  • The Route’s Vehicle Dynamics Control System delivers power with silky precision.
  • 1100 ft/lbs torque drive power

Unlimited Range

  • The microturbine generator keeps the Route going all day on Diesel, CNG, LNG, or landfill gases.
  • Turbines offer great power-to-weight, and their simple architecture makes them durable and easy to maintain.
  • Airlines and electricity plants also use turbines for their efficiency and durability.

The GTD (Geared Traction Drive)

Wrightspeed was able to make the fully integrated GTD by designing the inverter, 250 hp motor, and multi-speed transmission from the ground up, optimizing compatibility and system efficiency.

This Silicon Valley “systems approach” has yielded an exceptionally high-power, compact, and lightweight system. Wrightspeed’s Drivesystem is geared to optimize low-end torque, for hauling up hills, while preserving top highway cruising speeds.

Wrightspeed demonstrates software controlled clutch-less shifting

Wrightspeed’s Powertrains move the complexity from mechanical systems into electronic and software systems, making them lighter, cheaper, and more efficient. Clutchless gear shifting is a good example of this:

Traditional multi-speed transmissions use clutches (synchro rings, multi-disc wet clutches, twin-clutch arrangements) to achieve synchronization before engagement; this makes them, heavy, expensive, and less efficient. But with electric motors, it becomes possible to control the motor speed so precisely, and change it so quickly, that the shifter dog-clutches can be engaged without clashing. The sync function that used to be performed by mechanical means has been shifted into software control of electronics, driving the electric motor with precision. The system is therefore lighter, cheaper, and more efficient. Wrightspeed’s control software weighs nothing, costs nothing to manufacture, doesn’t wear out, and uses the electronics that are already present to drive the motor.

The Wrightspeed GTD is shown here, on a dynamometer, simulating acceleration from stop to first gear, shifting to second gear, back down to first gear and then a full torque stop. The shifting is too quiet to hear. The sound produced here is the motor accelerating and decelerating at maximum torque. The GTD jumps when the motor changes speed due to torque reaction (torque reaction can be observed under the hood of a conventional car, when accelerated hard in neutral).

Simulated Truck Acceleration, Full Torque Stop

  1. Motor is accelerated to 20,700 rpm in first gear, Upshift (Shift from 1st gear to 2nd gear)
  2. Motor torque is reduced to zero
  3. Shift actuator is moved to neutral position (mid-stroke)
  4. Motor speed is synchronized to the correct speed for second gear, 9000 rpm (80 ms)
  5. Shift actuator moves to second gear
  6. Torque is reapplied to maintain “vehicle speed”, Downshift (Shift from 2nd gear to 1st gear)
  7. Motor torque is reduced to zero
  8. Shift actuator is moved to neutral position (mid-stroke)
  9. Motor speed is synchronized to the correct speed for first gear, 20,700 rpm (80 ms)
  10. Shift actuator moves to first gear, Full-Torque Traction Drive Stop
  11. Motor comes to full stop
