| - 3 - Works, G. {Mr Griffiths - Chief Accountant / Mr Gnapp} Radcliffe. Let it be said here and now that Radcliffe's trip was a perfect rest cure, in which his most arduous task was to see that adequate supplies of petrol were put into the tanks at rare intervals. Both cars got back to Paris as they had left, without the slightest mishap, either mechanical or otherwise. And yet, you will see how remarkable was the performance of the "Stream-line". In spite of the astounding averages realised, we did not have so much as to tighten up a plug. And this applies both to the "Streamline" and to the standard car. From Paris to Metz, we covered exactly 300 Kms. at an average of 105 k.p.h. Between Châlons and Ste Menehoulde this average rose to 128. Once on the Autobahne, Sleator gave the "Stream-line" her head and the following figures were reached, which we would ask you to consider as the timings of a car which, even at its highest speeds, is always perfectly silent and smooth; which never vibrates at any engine speed and which - and this is a danger from which future drivers of the "Streamline" must guard themselves- never gives the impression of its actual speed. It always remains a Touring Sports Car rather than a car built solely for speed. Its road holding qualities, its springing, its easy steering are, let it be said again, those of a car built for comfort. | ||
