A single word that captures the passion andcommitment that has
revived Nissan and drives our
future. Everything we touch, we shift. And everything
we shift, we try to make better and uniquely Nissan.
What does "SHIFT_" mean at Nissan?
SHIFT_ thinking changes the way we look at things,the way we do
things and the way we react to life
around us. It is more than kaizen. It's no longer about
just doing, but doing for a purpose, doing effectively.
It is change, but change driven for better, faster,
higher performance. Our job is to create value, andwe believe
great products define a great carmaker.
We are not afraid to take the lead at times or to
stretch the boundaries in wider, better directions.
When you change the way you look at reality, you will
find that amazing things can happen. That's the
NISSAN spirit -- the Nissan SHIFT_.
