Toyota went for broke at the world’s largest custom car show with a range of off-the-wall concepts and race-inspired specials by some of Japan’s leading design and race engineering houses. Toyota descended on the 2012 Tokyo Auto Salon, described as the world’s largest custom car show, with a number of concepts and special-edition models to add a touch of athleticism to its range. GRMN (or Gazoo Racing tuned by MN) is, for example, showing a second-generation of its iQ Supercharger prototype. The model is scheduled for a limited production run of 100 later later in 2012.The car is powered by a further development of the supercharged 1.33-litre engine previously used by GRMN in the iQ 130G MT that delivers 95kW/180Nm. It has a six-speed, close-ratio transmission, uprated brakes, sports suspension and a tuned dual exhaust system.MAKEOVERS ABOUNDAs well as hotter performance, the car gains a new look thanks to a full body kit, including rear spoiler, sports seats and instrumentation. and 16" Enkei alloys.GRMN has also given the new Yaris a makeover.
