-7- We think that the car is somewhat over-geared for the normal user. Its very high top gear also affects the lower ratios, the result being that the 2nd gear is just too high for climbing passes, and the bottom gear unnecessarily low. We think that a 5% lower axle ratio is desirable for English cars at any rate, and also a slightly lower second gear, but this latter feature may not be possible if we are to avoid departing from rationalised parts. RADIATOR GRILLE. The radiator grille will require modifying to obtain a greater margin of safety on cooling. PETROL TANK. The petrol tank is just a little too small to enable the run from Paris to Lyons to be carried out without a fill up. This can be modified. BODY. The column support wants improving as on 30-G-VII. The ventilation needs improving. The rear ventilating windows fell out and require more adequate location. The panel which covers the rear wheels needs slight modifications to improve accessibility. Mounting the body solidly to the cross has brought up propeller shaft noise which is not tolerable. This mounting must be modified. The bonnet fasteners are not man enough for the job. Generally speaking, however, the car was exceedingly comfortable to sit in, and agreeably roomy for a Sports car, also the coachwork was commendably free from rattles at the end of the run. The doors, of course, require balancing to facilitate ingress. Since coachwork is the main feature of this car, we have handed it over to Van Voorens to enable Paulin to rectify the necessary faults, and as soon as this has been done, we shall experiment with the directional stability of the car. We consider that as almost all the parts of this car have done 50,000 miles' test on B.8.V., and that the tests on the same parts are being repeated on 30.G.VII, it is more | ||
