IBB/FB. 1012 LUGGAGE BOOT CAPACITY. In drawing the first S.30 body, an endeavour has been made to establish the luggage accommodation that the average owner of this car will consider to be desirable. In order to get a basis to start from, we have made a brief survey of our present practice, and compared it with what is being done on up-to-date American cars. Having definitely decided on the spare wheel at the side on S.30, we begin with a better chance than the Americans who almost invariably have to accommodate a wheel as well as the luggage in the boot. We expect to lose some of this advantage due to our lower overall height of car. To facilitate the investigation small wooden models were made to represent average dressing cases, suit cases, golf clubs, etc. We recommend these as useful yard sticks to assess the merits of any luggage boot drawing with rapidity. It is at once apparent that the shape of the boot is almost as important as its actual cubic capacity. The ideal minimum size and optimum shape for the maximum amount of our model luggage appeared to be, roughly, - [Diagram of a trapezoid with dimensions: top 16", bottom 30", height 23"] Considering our own cars that at present exist. The worst boot of any is on the close-coupled experimental Wraiths. This seems to be due to the | ||
