Mitsubishi Motors’ North American Version of i-MiEV to Make World Premiere at the LA AUTO SHOW
Tokyo, November 9, 2010 – Mitsubishi Motors Corporation (MMC) will give the world premiere of the North American version of its i-MiEV new-generation electric vehicle at the LA AUTO SHOW (LAAS) held at the Los Angeles Convention Center from Wednesday, November 17 to Sunday November 28 (open to the general public from Friday, November 19). In addition, the Outlander Sport compact CUV (RVR in Japan, ASX in Europe), which is to go on sale in the North American market from the end of this year as well as other core vehicles for the North American market are planned for display at the LAAS.
The North American version of the i-MiEV, in comparison to the Japanese- and European-spec i-MiEVs, features an enhanced, enlarged body structure to secure plenty of space for four adults and better meet the expectations of U.S. consumers. In addition, the North American-spec i-MiEV’s front and rear bumpers are all-new. Airbags that detect passengers’ seating position and control deployment force, Tire Pressure Monitoring System (TPMS), and Active Stability Control (ASC) are all standard equipment.
Also, with the Outlander Sport’s mating of a 2L MIVEC*1 engine to an INVECS*2 III-CVT Sportronic (six-speed sport-mode CVT) transmission (five-speed manual transmission also available on some trim levels), the Outlander Sport provides superior motive performance, fuel efficiency and low emissions in a compact CUV package that can seat five.
