Nissan North America overall was up in June 2011 vs June 2010, Nissan up 16.7%, Infiniti down 24.3%. Shortages after the earthquake caused supply shortages for Infiniti.
The Nissan LEAF sold 1708 units in June, bringing the total sales to 3875 units for 2011. The Nissan GT-R sold 99 units, bringing the total for the year to 827 cars. This obviously means that that LEAF is at least four times, but maybe seventeen times more popular than the Nissan GT-R.
