Thanks Jerry, what had confused me was this explanation below…
“Refers to French auto designer de Dion and his independent rear suspension that utilizes a connecting tube. Rear suspension system which allows the wheels to retain their correct camber no matter how much the suspension is deflected. In a typical application, two tubes run across the car, one being free to telescope slightly inside the other, and the wheel hubs are fitted to these tubes by rigid arms. The track is controlled by fixed-length halfshafts connecting the hubs to the differential, which is attached to the underside of the car. In this way, torque reaction is taken by the car frame, and the car's unsprung weight is reduced. De Dion suspension is a long-established system used by, among others, Ferrari, Alfa Romeo and Rover.”
I’m sure that the De Dion tube is not telescopic and the half shafts are not fixed length but splined to allow for radial variation due to vertical movement of the wheels. I assume also that lateral movement of the whole arrangement is constrained by the vertical slot that the tube engages in (as shown in the photo) I assume also that this engagement prevents the tube from rotating around the fore and aft axis of the car. Makes sense now, Cheers.

I have it and it's companion book Sports Cars. I haven't looked at them in years. Rainy Sunday here, maybe time to pull them off the shel, dust them off and have a good look! 😁

The Clutton name rings a bell as Sam Clutton (Son of author?) used to race a 1905 Itala GP Car at Castle Combe and Prescott Speed Hillclimb in 1964-69. There was also an Edwardian Metallurgique GP car to spar with it occasionally. An amazing and impressive sight and noise.

A book that I borrowed from a friend a year ago and did so again today to refresh my initial impressions. A bad choice of ghost writer I believe since the whole tone of the book grates and celebrates his hedonistic lifestyle. There is some good historical content and also some amusing anecdotes however the last page says it all! Sorry to Hawthorn, Moss, Hill, Clark, Surtees, Stewart, Mansell, Button and Hamilton but you have to know your place. I have always rated Coulthard and enjoy his TV input but this book disappoints.

Wasn't he World Champion...in his mind? 😁

I would place all of those drivers you listed above Mr Coulthard, Stewart (OK, so Mansell is only ahead as he drove a Ferrari ) . I always considered he thought of himself a fair bit higher than the general populace did, and he did get thumped my Mika Hakkinen!. Having said that I can't actually see him saying the words on that last page! Based on your recommendation, it is a book I will avoid.

Results count of course. I've had the pleasure of meeting DC at McLaren Woking where he was doing a F1 seat fitting and a couple of times since then. Decent bloke who does a reasonable job as an F1 Pundit on Channel 4. Looks like I'm going to have to read the book... Martin has written many successful books centred around the pop music industry. Science of the Supercar and Bugatti Veyron are two of his books.

Science of the Supercar and Bugatti Veyron are two of his books. Obviously an exceptional driver who was mistreated by Ron Denis and probably deserved a World Championship at McLaren. I just look forward to a better book to do him justice.

That does look like a great book! Lots to retain hours of time absorption in there!

This is a book that I purchased in the late 1960s and is the engine tuner’s bible. First published in 1948 it is as relevant now as it was then. The Contents sets it out. This is obviously not light reading but is well written by Phil Irving and has inspired such as Keith Duckworth and Colin Chapman. It has many good line drawings and essential formulae.
