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 introduced in North America more than 10 years ago.
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 RPM's. 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 torque at 1,000 to 1,500 rpm (123 lb-ft on CVT-equipped models). Estimated fuel economy ratings are city/highway/combined 5.6/5.0/5.3 L/100km with CVT and 6.5/5.3/6.0 L/100km with 6-speed manual.

The standard six-speed manual transmission is engineered for optimal acceleration performance in gears one through five and for optimal fuel economy in sixth gear. When starting on steep inclines from a stop, hill start assist temporarily prevents the vehicle from rolling backwards during the moment between releasing the brake, depressing the throttle and releasing the clutch (for a duration of approximately 1.5 seconds).
The available CVT provides the convenience of an automatic transmission with a seamless transition between minimum and maximum ratios, while also keeping the engine within an optimal RPM range for overall efficiency. To increase the performance potential of the CVT, paddle shifters located on the steering wheel allow the driver to manually simulate the stepped holding pattern. In Sport mode, the paddle shifters will hold and maintain a selected ratio.
The CR-Z's three-mode drive system allows the driver to select between individual modes of performance for Sport, Normal and Economy driving styles. The Sport mode enhances multiple vehicle systems for performance including the engine throttle responsiveness, electric power steering effort and the electric motor power assist. The inner ring of the tachometer illuminates red when the vehicle is in Sport mode.
During Econ mode operation, the engine's responsiveness is tuned for optimal economy, the electric motor assist gives priority to fuel efficiency and the air conditioning system can reduce its overall load on the engine. The inner ring of the tachometer transitions between blue and green when the vehicle is in Econ mode, with the green representing more ecological driving.
Normal mode provides standard settings for steering, engine response, motor assist and air conditioning. Similar to Econ mode, the tachometer ring transitions between blue and green when the vehicle is in normal mode, with the green representing more ecological driving. Like the Honda Insight, the CR-Z offers an Eco Guide and Eco scoring feature to help drivers track progress of efficient driving styles.
The front MacPherson strut suspension and rear H-shaped torsion beam suspension settings are tuned to provide a sporty, solid and dynamic driving experience. All models are equipped with 16x6-inch aluminum wheels with 195/55 R16 86V tires. Accessory 17x7 alloy wheels with 205/45R17 84V tires are available.
The CR-Z demonstrates a commitment to safety in its design and construction. The Advanced Compatibility Engineering(TM) (ACE(TM)) body structure helps protect vehicle occupants in a frontal collision. Additional safety technologies include standard dual-stage, multiple-threshold front airbags; standard front-side airbags with passenger-side Occupant Position Detection System (OPDS); side-curtain airbags, active head restraints; an anti-lock braking system; a tire pressure monitoring system; and a pedestrian injury mitigation design in the front of the vehicle.
