For Porsche 928 enthusiasts, understanding the nuances between European (Euro) and United States (US) specification models is crucial, especially when considering import vehicles. While both versions share the iconic 928 DNA, several key differences set them apart. Identifying these variations can be essential for collectors and buyers alike.
One of the most visually apparent distinctions lies in the headlights. Early US-spec 928s, and some early Euro models that underwent federalization for US import, were fitted with smaller, 7-inch diameter headlights, characterized by a chrome trim ring. In contrast, standard Rest of World (ROW) and later 928 models boasted larger, 8-inch H4 housings. While regulations have evolved, and importing a 928 into the US today doesn’t automatically necessitate headlight changes, this remains a classic visual cue.
Beyond headlights, side marker lights offer another clue. Euro imports exhibit varying configurations: some feature side markers both front and rear, others only at the rear, and some none at all. This contrasts with the more standardized side marker setups often seen on US models due to regulations. Another structural difference to note is the potential inclusion of side impact door beams in some Euro specifications, an addition that might not be universally present in US versions of the same era.
Moving inside the cabin, the speedometer typically underwent a conversion for US imports. Originally calibrated in kilometers per hour (KPH), Euro models destined for the US market had their speedometers changed to miles per hour (MPH). Interestingly, despite this conversion, other instrument gauges and warning lights often retained their original German labeling.
When examining a 928’s origin, the Vehicle Identification Number (VIN) is a natural point of inspection. Early Euro 928 VINs lacked a specific designation to immediately flag them as European. However, with the introduction of the 17-digit VIN system, a “ZZZ” prefix emerged as an indicator for Euro models. Despite the VIN, it’s crucial to remember that a Euro VIN alone doesn’t guarantee the presence of all Euro-spec components. Parts could have been swapped or changed over the car’s lifespan.
Engine specifications also present potential variations. Particularly when considering 928s from the 1980-1982 period, some Euro models were equipped with a 4.5L engine producing 229 horsepower. Simultaneously, the “S” models featured more powerful 4.7L engines delivering around 300 horsepower. To definitively ascertain the engine specifications, verifying engine block stampings and casting numbers of internal components is advisable, as engine parts could have been replaced or modified over time.
In conclusion, while visual cues like headlights and side markers, along with documentation such as the VIN and speedometer, can offer initial insights into a Porsche 928’s origin, a thorough inspection is paramount. Factors like engine specifications and component details require careful verification to accurately determine if a 928 truly embodies European specifications. For prospective buyers and enthusiasts, understanding these nuances ensures a more informed appreciation of these iconic vehicles.
