The other advantages which we expect from the subframe, like less wear and tear on the bodywork, can only be proved out after many thousands of miles, but we know that we have thousands of bodies running without subframes so that it is not practical to make a satisfactory body without a subframe. In the case of the 20 HP. Although all Experimental cars are fitted with subframes, these are not used on production and there is no real difference in the results of the subframe and non-subframe cars. As regards the spare wheels. When we were at W.W. the other day, DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}, stated that he thought about only 5% or 10% of our cars were carrying the spare wheel at the rear. The accepted standard was two wheels at the side. This would be an interesting point to have confirmed. HS.{Lord Ernest Hives - Chair} | ||
