Fast Facts:
  • As successful as the 911 was, Porsche was worried that the 911 concept would run its course before they could offer a successor. To replace the 911 would be harder than replacing the 356 – it had to be evolutionary. The car would have to be advanced enough and, most importantly, look futuristic enough to survive a 15 year production run (just like the 356 and 911 did)
  • To do this, Porsche essentially had to build what they envision would be a ’90s sports car … in the mid ’70s! This meant full body-colored bumpers for a monochrome look, an all-aluminum water cooled OHC V8, pop-up headlights, and aluminum body panel construction to reduce weight
  • Even the construction of the engine was ’90s grade tech. The bores were electro-chemically embedded with silicone crystals to reduce friction and wear (again, pre-dating the Nikasil coated cylinder bores of the ’90s). The design was an overhead-cam V8 with a highly oversquare design (a race engine-like 1.2 bore to stroke ratio). Internals consisted of a forged crankshaft, forged rods, and iron-coated aluminum pistons. The water-cooled design was to meet what they predict to be ’90s emissions requirements
  • Porsche was the only manufacturer at the time to offer a front engine/rear transaxle sports car (a setup not seen until the arrival of the C5 Corvette – again, ’90s tech). Putting the transmission in the rear allowed for a 51/49 weight distribution. The transmission had no overdrive – 5th gear was direct drive 1:1. In addition, the shifter was a dogleg design, but not for racing purposes – engineers assumed the V8 torque was enough to pull from a stop in 2nd gear, rendering 1st gear for occasional use only
  • The 928 was one of the first vehicles to use mostly aluminum throughout its entire construction (doors, hood, fenders, engine, etc. The rest of the body was galvanized steel, minus the bumpers). The aluminum panels were stiff enough to withstand 5 MPH impacts without damage. Combined with Porsche’s extensive 26 step paint process, the 928’s body is highly resistant to rust, allowing Porsche to offer a 10 year corrosion warranty on the 928 (many cars of today only have a 7 year corrosion warranty)
  • The 928 also featured one of the earliest forms of passive rear-wheel steering systems, referred to as Porsche’s Weissach axle (a variant of the semi-trailing arm suspension). The design laid the foundation for modern rear wheel steering – it would automatically self-adjust itself during a corner by inducing rear wheel toe-in
Key Model Year Changes:
  • First year of the 17 digit VIN number
  • 1981 saw virtually no changes
  • 1982 cars simply gained an MPG gauge that could display real-time MPG
  • 1978-1982 cars are identifiable by their smooth body lines (no aero). These cars are powered by 4.5L V8s (later cars have 4.7L V8s)
  • The previous year (1980) saw notable improvements: 220 lb weight savings from a lighter aluminum torque tube, hollowed-out transmission mainshaft, and hollowed-out front sway bar. 1980 cars also gained extra torque via increased compression, improved valve timing, new L-Jetronic fuel injection, and relocated spark plugs that move the tip 4mm closer to the combustion chamber
