The 2013 Honda CR-Z is powered by the same 1.5L 4-cylinder engine as the models currently in US showrooms but thanks to a new camshaft, a retuned variable valve timing system and a new engine control unit tune, the 2013 CR-Z gasoline engine offers 120 horsepower – up from the 112 offered for the 2012 model year. Next, the electric assist portion of the CR-Z’s hybrid drivetrain has received a new lithium ion battery that produces 20 horsepower compared to the outgoing Nickel Metal Hybrid (Ni-MH) battery setup that offered just 14 horsepower. The 2013 CR-Z also features a new Plus Sport boost system that offers increased acceleration power when the battery is at least 50% charger. The system is activated by the S+ button on the steering wheel (shown above on the right) and when the driver hits the gas – the electric boost system engages and provides more power to the wheels for up to 10 seconds. The S+ system works in ECON, Normal and Sport modes with a gauge on the dash to let the driver know when the system is active and available.
When the revamped gasoline engine and the new battery system work together, the Integrated Motor Assist (IMA) system of the 2013 Honda CR-Z offers a total figure of 135 horsepower (+13hp) and 140lb-ft of torque (+12lb-ft). This increase in power for the 2013 model combined with the Plus Sport mode equates to a 0-62 time that is 7 tenths of a second quicker than the outgoing model (now 9 seconds flat) and a top speed of 124 miles per hour.
