Nissan along with other SUV makers is facing big sales declines in face of gas prices. Nissan is behind the curve on hybrids and is putting a Toyota engine in the Altima. So what will they do to restore X sales in 09? Will have to be something for gas mileage, that's obvious.. but what? Four cylinder version? By the way, sales of Xterra, Pathfinder and Frontier are about equal and all in decline .. Frontier declined least.)
