Honda says its new CR-Z hybrid hatchback is supposed to hearken back to the days of its sporty little CRX, so it’s anything but surprising that Mugen, the Japanese automaker’s tuning company of choise, is showing off its package of accessories for the model ahead of its official sale date.

Honda is introducing the one-person 3R-C concept to the public at the 2010 Geneva International Motor Show. The battery electric-powered single-seater takes a look at how future mobility problems in urban areas might be solved using clean technologies.

Most, if not all taxis on the other side of the pond run on diesel or LPG, but Honda believes it might be able to convince some European cabbies to try out its Insight and Civic mild-hybrid models. Both cars come in appropriate exterior colors and are equipped with pre-installed roof brackets and a mounting for the taxi-meter on the dashboard as well as some other special equipment such as heavy duty floor mats.

While many Japanese aftermarket tuners are taking on the newest models including many of them turning towards European applications, J’s Racing has stuck to what they know best: Hondas. The company’s booth wasn’t overwhelmingly large, but it was clear that J’s Racing is aware of the new Hybrid-tuning craze, displaying its own version of a tuned Insight, complete with light-weight RAYS wheels, an aero kit, lowered suspension and some nice Recaro seats inside. It even featured a unique combination of decals that gave it a widebody look.

Today, Honda officially introduced its all-new HSV-010 GT Racing car with which it will compete in the GT500 class of the Japanese 2010 Super GT series. The HSV-010 GT, which will take the place of the racing variant of the NSX, is all that has been left from Honda’s V10 powered supercar project that got canned at the end of 2008 due to the recession.
