Page "Nissan S130" Paragraph 4

The 280ZX's body was redesigned with aerodynamics in mind.

By closing in the open grille of the first generation Z-Car and through other improvements taken from wind-tunnel testing, the drag coefficient was reduced from 0. 467 to 0. 385, and the lift coefficient from 0. 41 to 0. 14.

The new design had a lower center-of-gravity and near 50 / 50 weight distribution in both 2-seater and 2 + 2 designs.

The rear of the car was stretched to accommodate a larger 80 L ( 21. 133 U. S. liquid gallons ) fuel tank.

Overall, the new body design gave better fuel economy and high-speed stability ( one of the known issues from the first generation Z-car ).
