Mercedes Benz's 600 unwanted functions
In May 2004, faced with a barrage of criticism about recalls (including one for a new electronic braking system that could fail), a Mercedes executive publicly stated that the company had removed no fewer than 600 electronic functions from its cars. What did they all do? Clearly nothing very useful, as nobody ever noticed they had gone.
Austin Metro reversing lights (1980)
When the Metro was launched, the basic version did not get reversing lights - you had to buy the more expensive model to enjoy safe reversing in the dark. However, it was much simpler to have only one wiring harness and one set of rear lights for all models. So the base models had reversing lights - but the little 5p bulbs were not fitted. Some enterprising garages offered to fit them while the car was in for servicing - at rather more than 5p.
Ford DOHC 8 valve (1988)
At the start of the 1980s, the Japanese started the trends towards 16 valve four-cylinder engines, and soon it was clear no-one would design a large 4 cylinder engine with only 8 valves any more. Except Ford, apparently. In 1988, to general bewilderment, the Sierra and Granada appeared with a new DOHC (twin cam) 8 valve engine. Even at the launch, Ford people quietly hinted that the engine was not long for this world and it died when the Mondeo was launched in the early 1990s with a 16 valve engine. The words, "false" and "economy" spring to mind.
VW Polo Harlequin (1995)
Quite why VW would want to turn a perfectly sensible supermini into a clown's car is anyone's guess. Not surprisingly, it was a difficult car to sell, until a bright salesperson hit on the idea of selling them to driving schools. As each body panel was a different colour, repairing scrapes was much cheaper - there was no need to match the colour of different panels.
Fiat Bravo immobilizer (1995)
Fitted to a number of 1990s Fiat, this was a good idea in principle - an inertia switch that would cut all electrical power in an accident. What was not so sensible was putting it under the driver's seat. Jump in a bit too enthusiastically, and the car could point-blank refuse to start.
Austin Allegro quartic steering wheel (1974)
The ultimate silly idea. Apparently the designer of the Allegro (yes there really was one) doodled a dashboard with a slightly squared-off steering wheel. The boss of Leyland, Lord Stokes (a man who never met a stupid idea he didn't like) saw it and decreed that it should go into production on the Allegro to demonstrate its modernity. No doubt, if he could have found square tyres, it would have had those too.
Subaru wiper actuated four-wheel-drive (1988)
Subaru is known as Japan's most eccentric car company, but this was extreme even for them. The Subaru Coupe Turbo had a system that automatically turned the transmission into four-wheel-drive whenever the wipers were switched on. After all, a few spots of rain in the Tesco car park do make four wheel drive an essential requirement.
