This powertrain is the sixth and latest iteration of the one in Honda's other two hybrids, the Civic Hybrid and Insight, and pairs a small displacement, four-cylinder engine, in this case a 1.5-liter, 16-valve single-cammer, with a brushless DC motor positioned in place of the flywheel. The 10-kilowattmotor/generator pulls double duty, helping accelerate the CR-Z and capturing kinetic energy in a 100-volt nickel metal hydride battery during braking and coasting. Engine and motor combine to deliver 122 horsepower and 128 pound-feet of torque (123 pound-feet on CVT-equipped models), making the CR-Z the most powerful hybrid in Honda's lineup, but also its least fuel efficient. With the standard six-speed manual, Honda estimates the CR-Z will achieve an EPA rating of 31 city and 37 highway mpg. With the optional continuously variable transmission, mileage improves to 36 city/38 highway mpg, but that's not great for a hybrid, especially one sprung from the loins of the original Insight, which managed a staggering 70 highway mpg (61 in 2008 parlance).
