ORIGINAL R7/M20.10.28. CARS - RIDING QUALITIES. REAR END. X7410 X7600 X7830 X507 DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} ismaking a series of small drawings shewing on each of our chassis our suggested treatment of the rear end with different lengths of bodies. As the riding and steering qualities are so influenced by the weight distribution, and the passengers' comfort depends to a great extent on the seating position, we think this is of the utmost importance, and should be issued with every coachbuilder's drawing, and supplied to customers when they are choosing or ordering a body. The series of drawings starts from a very short body and large trunk behind, with one or two spare wheels behind this, to the longest possible body, no trunk, but spare wheel or wheels behind, which is a luggage carrier for emergency use. It will be realised that there is a limit to the length of the car for general convenience - traffic, garage, parking, etc, so that when a long body is demanded, ideal conditions are impossible, and other advantages cannot be given. In no case do we recommend a side wheel carrier. We now consider that weight carried here is bad, and the appearance ugly. R.{Sir Henry Royce} | ||
