At the 2017 Tokyo Auto Salon, Mugen, Honda's tuning subsidiary, debuted the Mugen GARU, a customized version of the Honda S660 roadster. Little information was released about the GARU, but it was visually distinct with custom body panels except for the lights and door handles. Despite its modest power, the GARU sported a striking appearance with a wide-body design and large rims, prompting comparisons to the Bugatti Veyron's front end.
