Mugen's high-performance version of the Honda CR-Z will be supercharged, delivering over 50 percent more horsepower and torque than the stock hybrid hatchback. The tuned version of the gas-electric coupe is expected to crank out approximately 200 horsepower and 181 pound-feet of torque. The modified vehicle retains Honda's IMA electric motor and the original 1.5-liter i-VTEC gasoline-fueled engine, which has been rebuilt to Mugen's specs with upgraded internal components.
Colin Whittamore of Mugen Euro explains the unique setup of the modified CR-Z like this:
Aside from the modifications found under the CR-Z's bonnet, Mugen tuned the hybrid's chassis by fitting it with five-step adjustable dampers front and rear, increasing its track width and reducing its overall weight. Massive rotors and four-pot monoblock calipers help ensure that the Mugen CR-Z stops as directed, while 17-inch forged wheels reduce unsprung weight.The idea was to use the significant advantage of the early torque provided by the Honda IMA electric motor, then increase the torque available from the petrol engine gradually, to first maintain and then increase this. A supercharger and complementary electronics allow us to very neatly map the IMA to the extra power and torque of the engine in a unique package, giving a smooth and integrated powerful driving experience.
The Honda CR-Z Mugen will make its official debut at the Goodwood Festival of Speed in July. At this time, the CR-Z Mugen is purely a one-off prototype, with no plans for a production version.
