The last time Honda and Mugen teamed up was a couple years ago with the 2009 Civic Type R Mugen. And now, the two are back again, only this time they've gone for a more, shall we say, eco-friendly option (don't hate). The Honda CR-Z Mugen is powered by the regular 1.5-liter-VTEC engine with 113hp. However, Mugen has added a supercharger and has tinkered with the hybrid system, resulting in almost 200hp and 181 lb-ft of torque.
In order to save weight and make it more agile, Mugen technicians have cut out nearly 110 pounds from overall weight. The hood is made from carbon fiber and the wheels are Mugen's own lightweight alloys. Although there are front and rear end spoilers (that certainly adds weight), Mugen claims they're there to improve aero drag. Early prototypes tests have resulted in a 0 to 60mph time around that of the Civic Type R (roughly 6.6 seconds). Early fuel consumption tests have also been positive, with the standard CR-Z's three driving modes remaining.
It's so far returned around 50 mpg + in Eco mode and a mid-30 mpg result when in a special supercharged Mugen mode. We'll get full details of the car when it premieres at the 2011 Goodwood Festival of Speed.
