Just for giggles I'm going with 'backwards.'
The Porsche, loosely designed around Ludwig Prandtl's 'Lange Car',an out-growth of Jaray's combination-form design,while not great,aerodynamically,can serve a family of four in reasonable comfort.
The 928s aft-body will make a fine fore-body. And yes,there should be separation at the windshield header and the flow might not ever re-attach,but with the nose stuffing the wake,and forcing the area the turbulence can occupy,it might be reasonable to expect an overall drag reduction.
I hope the folks at Chrysler are watching,they actually did this with the 1933 DeSoto sedan for a significant top speed and mpg increase while driving coast-to-coast across the U.S.,'backwards!
