LEAF system named to Ward’s 10 Best Engines
Ward’s has announced that Nissan LEAF’s 100
percent electric, zero-emission drive system is included on its
prestigious ‘10 Best Engines’ list for 2011. It is the first
time in the 17-year history of the magazine’s ‘10 Best Engines’
that the selection committee has chosen a power system which
doesn’t have an engine and will never burn a drop of gasoline.
For 2011, 38 competitors were considered, marking the largest
group in the history of the award. The competition included both
naturally aspirated and forced induction internal combustion
engines, diesels, hybrid electrics and the all-electric Nissan
LEAF. The editors evaluated the vehicles based on horsepower
and torque; noise, vibration and harshness; the engine’s technical
attributes; and their relevance among direct rivals.
The all-new Nissan LEAF features a high-response 80kW AC synchronous
motor powered by a 24 kWh lithium-ion battery manufactured at
the Automotive Energy Supply Corporation operation in Zama, Japan,
which is a joint-venture of Nissan Motor Co., Ltd. and NEC Corporation.
Both motor and inverter have been developed by Nissan, and the
power system generates 107 hp and 207 lb.-ft. of torque. The
power is transferred to the wheels through a single-speed reduction
Unlike a conventional internal combustion engine, Nissan LEAF
delivers maximum torque from start, providing smooth, consistent
acceleration. Performance in the low-to-medium speed range is
equivalent to that of a vehicle powered by a V6 gasoline engine.
This power system provides a highly responsive, fun-to-drive
experience consistent with consumers’ expectations for traditional,
The 2011 Nissan LEAF went on sale in December in selected markets
in the United States and will be available nationwide in 2012.
The awards will be presented at a January 12, 2011 ceremony in
Detroit during the North American International Auto Show.
