Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} HS.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} PEREGRINE 2. X158 DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}22.1.32. X.4027. In order to come to some decision as to what should be the weight of the Peregrine chassis, and the weight of the finished car, we have made the attached analysis which is of interest. Peregrine has a capacity equal to the average in the class, but is 4" longer. We think therefore if we can make the chassis weight not more than 13.5 cwts, all on, including spares and accessories - (average 19.70 cwts), and the body at 8 cwts (average 8.15), we shall have achieved as much as it can be hoped we shall do. In the matter of pounds per litre, fully laden, we shall equal the average, but shall be inferiro to the Essex and Chrysler. The 14.9HP. Ford is a little superior, but is discounted by its four cylinder engine. The wheel size may not be correct, as since the October issue by the S.M.M.T. a number of cars have gone in for smaller wheels. DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} | ||
