The CR-Z represents the sixth unique version of Honda’s original IMA technology since the launch of the 2000 Insight, the first hybrid vehicle available in North America in December 1999. The foundation of the CR-Z’s hybrid powertrain is a 4-cylinder, 16-valve, single overhead cam engine with “intelligent” Variable Valve Timing and Lift Electronic Control (i-VTEC) that receives additional power from the IMA system’s DC brushless electric motor. The i-VTEC system controls the opening and closing of one intake valve per cylinder to enhance combustion at low RPMs. The 10-kilowatt electric motor assists in acceleration and also acts as a generator during braking or coasting to capture kinetic energy that recharges the 100-volt IMA nickel-metal hydride battery pack. The gasoline engine can automatically turn off during vehicle stops to improve efficiency.

The system delivers a combined peak output of 122 horsepower at 6,000 rpm and 128 lb-ft. of torque2 at 1,000 to 1,500 rpm (123 lb-ft on CVT-equipped models). Preliminary fuel economy estimates are anticipated to result in a rating of 36 city/38 highway miles per gallon on CVT-equipped models. Manual transmission models are anticipated to achieve an EPA-estimated fuel economy rating of 31 city/37 highway miles per gallon3. The CR-Z is rated as an Advanced Technology Partial Zero Emissions Vehicle (AT-PZEV) in states that adhere to California Air Resource Board (CARB) ZEV standards (EPA Tier 2, Bin 2 in all states).
