The Honda CR-Z Mugen is officially confirmed today with 197 horsepower from a supercharger instead of a turbocharger we had speculated earlier. The supercharged Honda CR-Z hybrid will make its debut at the Goodwood Festival of Speed in July.
The supercharger is added to the 1.5-liter i-VTEC four-cylinder engine, which integrated with an electric motor to produce 197 horsepower and 181 pound-feet of torque. And those numbers are within our speculation from previous report. If you calculate those numbers, they are about 50 percent more power and torque over the stock Honda CR-Z hybrid.
Adding a supercharger to a hybrid system is not exactly the same as to a conventional engine. Mugen had to develop its own iCF system in order to give a fully integrated and smooth power delivery.
“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,” says Colin Whittamore from MUGEN Euro. “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, integrated and powerful driving experience.”
