Integrated Motor Assist IMA

The ILX Hybrid is powered by the Integrated Motor Assist (IMA)® System which has been designed on the premise that much of an engine's power is only used during acceleration or on steep inclines. Thus, the system incorporates a 1.5-liter, 8-valve, i-VTEC® 4-cylinder gasoline engine along with an electric motor. The small, efficient engine operates alone when cruising at a steady speed while the electric motor assists the engine when additional power is required.

  • Together, the motor and engine produce 111 hp @ 5500 rpm while torque is 127 @ 1000-3500.
  • Connected exclusively to the continuously variable transmission, the engine has an EPA Estimated Fuel Economy of 39 miles per gallon in the city, 38 on the  highway and 38 combined.27
  • Under certain conditions, the electric motor alone can propel the car up to 45 mph.
  • Deceleration and braking recharge the battery that supplies power to the electric motor.
  • Though new to Acura, the IMA system has seen real-world use and been in continual development for over a decade.
Continuously Variable Transmission

The ILX Hybrid is equipped with a continuously variable transmission (CVT). The CVT works like that of a multi-speed bicycle, in which different ratios are achieved by changing the size of gears on each side of a chain. Yet instead of a chain with multiple gears on each end, the transmission uses a metal push-belt, running between a pair of pulleys that continuously vary their diameter.

  • Rather than the five or six ratios of common automatic transmissions, the CVT offers an infinite number so as to provide the most efficient drive ratio possible at all times.
  • When combined with the Drive-by-Wire? throttle, the CVT allows the engine to stay at its most efficient RPM while speed is adjusted largely by ratio changes.
  • Steering wheel-mounted paddle shifters allow you to switch between pre-determined fixed ratios to give you control of the transmission when desired.
