The vehicle can accelerate from a stop under electric power, using the electric propulsion motor to power the front wheels, with the gasoline engine decoupled from the drivetrain to minimize parasitic losses from friction. The system is designed so that the gasoline engine can act as a generator—this is done via the second motor in the two-motor system, a generator motor that is linked to the engine—that provides electrical energy to the propulsion motor to charge the lithium-ion battery. This is a "series hybrid" approach. The Accord Hybrid also operates as a "parallel hybrid" when the engine sends power directly to the drive wheels, supplemented, as needed, by the electric propulsion motor. When cruising at mid- to high-speeds, a lockup clutch engages to connect the drive motor and the generator motor to efficiently transmit engine torque to the wheels. The 2017 Accord Hybrid doesn't have a mechanical transmission (nor a torque converter). Rather, the operations of the gasoline engine and the two motors are coordinated based on driving needs. Compared to the 2014 model, the motors are smaller and lighter (on the order of 23 percent) and yet have greater performance, based, in part, on the use of three smaller, lighter magnets (rather than two larger ones) and square copper wire instead of round wire, which results in a denser, more compact stator. The propulsion motor is rated at 181 hp and 232 lb-ft of torque, which are improvements of 14.8 hp and 6 lb-ft, respectively. The generator motor is up 1.2 hp to 142 hp; its torque is the same as the previous generation, at 62.7 lb-ft. Smaller and lighter is a theme throughout the powertrain system. The PCU is 23 percent smaller and 27 percent lighter than the previous. The intelligent power unit (IPU), which combines a DC-DC converter and 1.3-kWh lithium-ion battery pack, is 33 percent smaller and 12.8 percent lighter. The size reduction is important because the IPU is packaged behind the rear seat, so by going smaller, there is an increase of 0.8-ft 3 in the trunk. The mass reduction is, of course, important in terms of overall vehicle performance: the new IPU weighs 99.2 pounds. Honda is committed to alternative powertrains. The Clarity fuel-powered vehicle is expected to launch before 2016 is out and a plug-in Clarity and an electric Clarity are scheduled for 2017. According to Conrad, by 2030 up to two-thirds of Honda's global sales will consist of "electrified vehicles," and he empha- sizes that this is electrification beyond stop-start systems. When it comes to multi- tasking, Hydromat is without peer. Whether it's for lower volume production needs, improved design for tighter tolerances, high volumes, or tooling development for tougher materials, we have delivered better solutions to our customers for decades.
