2010 Coda Sedan - click for high-res image gallery

Somewhat LEGO-like, the details of the all-electric 2010 Coda Sedan are coming together. We learned earlier this summer that the EV will use a 100 kW / 134 hp motor from UQM. This week, BorgWarner announced that its eGearDrive single-speed transmission will find a home under the hood of the electric vehicle, which will be introduced in California next year.

The Coda sedan will use BorgWarner's 31-03 eGearDrive, which BorgWarner says is "ideally suited" for electric drive vehicles. The highway-speed Coda Sedan will likely not be the only model to use this transmission, which is adaptable to a variety of systems, says BorgWarner Drivetrain Systems president and general manager John Sanderson. Read more pieces about the Coda EV here; there's more on the eGearDrive after the jump.

BorgWarner Announces eGearDrive(TM) Transmission Application on All-Electric 2010 Coda Sedan

AUBURN HILLS, Mich., Sept. 24 /PRNewswire-FirstCall/ -- BorgWarner announces another eGearDrive transmission application on the all-electric CODA sedan, scheduled for introduction in California in 2010. Ideally suited for full performance electric vehicles on either front-wheel drive or rear-wheel drive transverse driveline applications, the BorgWarner 31-03 eGearDrive(TM) single-speed transmission delivers high torque capacity, high efficiency, and low noise, vibration and harshness (NVH) in a compact package. Paired with a UQM TECHNOLOGIES, INC. (NYSE Amex: UQM) PowerPhase electric propulsion system, the BorgWarner eGearDrive(TM) transmission will propel the five-passenger CODA sedan at highway speeds while providing maximum powertrain efficiency.

"BorgWarner's 31-03 eGearDrive is a purpose built, high performance transmission that can be broadly adapted to a variety of electric propulsion systems," said John Sanderson, President and General Manager, BorgWarner Drivetrain Systems. "Designed for fast-to-market implementation, we expect this eGearDrive transmission to accelerate growth in the all-electric and hybrid electric vehicle segments."

In addition to providing primary drive for front-wheel drive and rear-wheel drive electric vehicles and hybrid electric vehicles, BorgWarner eGearDrive systems enable launch assist, energy recovery, and AWD performance for the secondary-driven axle on any type of vehicle. Also available is an optional electronically actuated park lock system as well as various electronic driveline disconnect systems.

      Would an ICE gearbox many any sense in an EV?
        • 6 Years Ago
        The only very clear application is in a supercar, where you want max acceleration in the low end and a very high top speed, but it seems most of the EV sports cars that are planned use only 1 speed, and do away with the high top speed, focusing on on the acceleration.
        • 6 Years Ago
        Some; the ICE gearbox matches output to demand. An electric motor has a broader torque curve than an ICE so, you can usually get away with the need for different ratios. It's easier in the EV domain to increase torque by adding more current than by changing gears.

        There are still some applications; off-road mode for example in a farm or construction vehicle.

      Can anyone explain the need and function of this unit? Why does an electric engine need this, to implement reverse?

        • 6 Years Ago
        You'd still want some reduction gearing so that you can get more torque at the wheels. Also I'm assuming there's a differential in this package as well. Reverse is done by just spinning the motor backwards.
        • 6 Years Ago
        do you really want a 1 to 1 ratio?
      • 6 Years Ago
      Wonder how different this unit is from the one they make for Tesla.
        • 6 Years Ago
        BorgWarner's 2008 press releases say the Tesla Roadster uses their eGearDrive system, but don't mention a specific model. It's hard to tell, http://www.borgwarner.com/products/tts/ is a joke website that doesn't mention eGearDrive let alone model 31-03.

        More manufacturers should eventually lower component costs. However, http://en.wikipedia.org/wiki/Coda_Automotive feels more like a defense contractor assembled to exploit some government program than a real car company. Look at the boards of directors and advisors: Chief of staff for President Bill Clinton, Henry Paulson, and a bunch of investment bankers and equity managers? They know how to lobby governments and do financial deals, maybe the Coda Sedan will be the GAO fleet vehicle of choice.
        • 6 Years Ago
        It might have a different gearing ratio, depending on what the maximum planned speed is and the different characteristics of the UQM motor vs. the Tesla motor.

        It is likely to have a different motor mounting arrangement, as UQM is unlikely to use the same bolting arrangement that Tesla uses.

        It would be kinda neat, and potentially money saving, if they were identical, though.
      • 6 Years Ago
      Isn't a single gear transmission the same as a differential? Shouldn't take too much to build that...
        • 6 Years Ago
        Not really. A differential is for splitting power between left and right wheels. However, it can be in the same package as the transmission. This is often called a transaxle.
      • 6 Years Ago
      American big engine cars of the fifties only had 2 or 3 gears (and an optional torque converter). Once the EV world focus changes to economy in stead of cost, more gears will follow.
