Newly Developed V6 MIVEC Gasoline Engine
Setsuo NISHIHARA* Takehiro NISHIDONO*
Abstract
This paper describes the new V6 engine developed for the new OUTLANDER sport utility vehicle
(SUV) for the North American market.
Since 2004, Mitsubishi Motors Corporation (MMC) has been refining gasoline engines for passenger
vehicles under the common themes of achieving higher performance, better fuel economy,
lower emissions, and weight and size reductions. MMC has thus far launched the 4A9 4-cylinder
engines (1.3 L and 1.5 L) for the COLT for Europe in May 2004, the 4B1 4-cylinder engines (2.4 L) for
the OUTLANDER for Japan in October 2005, and the 3B2 3-cylinder engines (0.66 L) for the ?i? in
January 2006. The introduction of the fourth engine, the 6B3 V6 engine (3.0 L), now completes the
lineup of these new-generation engines.
Like the other new engines, the new V6 engine offers class-leading performance in maximum
output and torque, etc., by employing such technologies as a variable valve timing mechanism, an
aluminum cylinder block, and a resin-made variable intake manifold. Furthermore, the new engine
weighs approximately 25 kg less and offers approximately 5 % better fuel economy than our conventional
6G7 V6 engine (3.0 L). In addition, through the use of high-performance catalysts, etc.,
the new OUTLANDER has acquired Super Ultra Low Emission Vehicle (SULEV) certification stipulated
in the California Low Emission Vehicle Regulations. Furthermore, by conforming to the zero
evaporative emissions regulations, the new OUTLANDER has earned the title of the first qualified
Partial Zero Emission Vehicle (P-ZEV) among the compact SUV category models with 3.0 L-class
engines.

Key words: V6, MIVEC, Gasoline Engine, P-ZEV
