From the left Vauxhall Ten; Ford Eight Y; Morris Ten; Vauxhall Light Six. Not enough definition to be more accurate. |

How many pages do you want me to write? Until the 1950s the British government taxed cars on the basis of a notional horsepower figure calculated by a formula. It was supposed to represent the power generated by the engine at 1000 rpm, and was the cylinder bore dimension squared, multiplied by the number of cylinders, divided by a constant which changed to allow for the dimension being in inches or mm. The length of stroke was not considered, resulting in a rash of long stroke engines, with high piston speeds and excessive bore wear. OK so far? As a result, a small car was either 7 or 8 horsepower, going upwards. You see this in the cars above. My Bentley is 32 hp, the largest American cars could be 40 or 45hp. This figure was then used to define the annual taxation of the vehicle, latterly at £1 per hp per year. I realise this sounds like a small amount now, but assure you it was substantial then. I now pay £535 per year for my Mercédès, but my Bentley, as a historic car is free. The manufacturers of cars frequently named them for the horsepower, or, as in the case of the Vauxhall light six, the number of cylinders, so that people considering buying a new model would have some idea how much road tax would be payable. Anyone wishing to comment is advised that I have missed much out for the sake of brevity. -- Last edit: 2021-08-18 10:49:38 |

Outwith the scope here perhaps, but the trams are a pair of 1922-34 Edinburgh Corporation standard cars, with a 1935-50 streamlined standard car in between. |
