The 928 is a true enigma. It seems impossible for a journalist to write a story about the 928 without citing the car’s failure to replace the 911, or the perception that buying one as a classic car is a potential minefield. But this is the very same car that was deemed the future back in 1977, and with good reason. This is the car – the only sports car – to win a Car of the Year gong. Ok, say what you like about this motoring equivalent of the European song contest, but for a sports car to win outright – that’s something quite profound. It is a car that always tried to be many things on four wheels, but as the years passed, was tasked with becoming a quite different sort of vehicle: an aggressive sports GT rather than an all-round everyday supercar.
The 928 project is thought to have begun in 1971, with the 911 already seven years old and great uncertainty over what the decade ahead would hold for the motor car. Significant pressure from lobbyists in America was threatening to make life next to impossible for sports cars – particularly rear-engined, air-cooled sports cars – and this threat was soon joined by the first fuel crisis. At Porsche there had been great changes, with the family withdrawing from the day-to-day running of the company, and Ernst Fuhrmann taking overall charge.
Influenced by the conditions around him, and guided by his crystal ball, he dreamed a new range of front-engined, water-cooled cars, headed by a formidable sports car that could equally play the role of a cross-continent GT.
Porsche knew the 911s limitations of the latter and were fed up with watching Mercedes and BMW mine a niche of wealthy customers who wanted to journey at speed in comfort. But Fuhrmann also wanted this new super-Porsche to set new standards in everything from accident protection to corrosion resistance. It was to be all things to all men: a 2+2 capable of 150mph, useable everyday, but with the handling and performance to shame most exotica.
What appeared at the 1977 Geneva motor show was a futuristic and unusual looking big coupe, powered by a 4,474cc single overhead cam-per-bank V8 featuring Bosch K-Jetronic fuel injection. Drive from the V8 was taken via a torque tube to a transaxle with the gearbox mounted ahead of the differential: either a five-speed dogleg manual, or a three-speed automatic sourced, ironically, from Mercedes-Benz. Weight distribution was claimed to be 51/49% front to rear.
The distinctive body design, by Wolfgang Mobius under the direction of Anatole Lapine, featuring ‘pop-up’ headlamps that remained uncovered even when laid flat, with doors, bonnet and front wings made from aluminium. Incredibly for the time, it had no obvious bumpers, these being hidden underneath plastic aprons styled to fit the car, and that could return to their shape following a minor impact. Today, we take such things for granted.
The suspension was sophisticated too: the front arrangement was a double wishbone and anti-roll bar affair, but at the rear Porsche broke new ground again and introduced the Weissach axle, a development of the semi-trailing arm setup, it countered unwanted toe changes during cornering, thereby reducing oversteer.
