 The 1924 Targa Florio Mercedes


Driving experiences by John Sutton

Sutton_Merc_Targa_Florio_3_.jpgSome people might say that I lead a charmed life and being asked to drive such a fabulous racing car is all it takes.  I should however point out that there is some luck and a lot of hard work involved.  No one is likely to ask a complete novice to drive such a car and so there is a long apprenticeship to be served.   Some of this has already been written about in the Features Section.


Sutton_Merc_Targa_Florio_1__1.jpgGerald Palmer bought the remains of the Mercedes in 1961 whilst he was assistant chief engineer at Vauxhall Motors, the same year I joined them as a lowly draughtsman.   I think he paid about £200 for this “restoration” project..  Gerald was however a very competent engineer, having been responsible for the design of the Jowett Javelin, MG Magnette and Riley Pathfinder.
 
I will not go into the details of how the car was restored and what modifications had to be made, but the Vauxhall Apprentice School was very busy for several months!

This was the car that won the Targa Florio in 1924 driven by Werner, and it must have been an epic drive as the car lay second on the last lap behind the Alfa Romeo which seized up about half a mile from the finish allowing the Merc to win.   Interestingly this was the only race in which the works Mercedes team ran with their cars painted red.   During practice the local Sicilians, who were very patriotic, rolled boulders down in front of any passing race car that was not painted red.   So Neubauer, the team manager, had all the cars repainted red between practice and the race.

This was a 2-litre twin overhead camshaft four cylinder engined car with a large supercharger driven via a clutch on the front of the crankshaft.   The supercharger was only engaged by a “kick-down” on fully depressing the accelerator pedal.   The car was a development by Dr. Porsche of the unsuccessful 1923 Indianapolis car.   The rear wheels were cambered in the same way as the front by means of a live rear axle containing two lightweight crownwheels.

 My first outing with the car was at Silverstone in a VSCC race.   In practice I soon discovered that the old tyres and lack of front spring leaf clamps gave rise to alarming wheel patter above about 60 mph.   I refused to drive it again until this had been resolved.  The tyres were balanced by the experts from Dunlop, who keep us all racing.   Spring clamps were hastily made of steel plates and bolts with locknuts.

Sutton_Merc_Targa_Florio_4_.jpgMuch speedier progress was now possible without total loss of control.  However as the horsepower is doubled when the throttle is fully depressed it is a fine judgement of timing when to apply this out of each corner.   Too early and the car spins anti-clockwise if you lift off – clockwise if you keep your foot down.    Too late and momentum is lost, there being a lag whilst the waste gate closes and the fuel system is pressurised.  This process is reversed as you lift off again.   Oh! – and I forgot to mention the centre throttle pedal and right footbrake arrangement.   Somehow I managed to win the race without keeping the supercharger engaged on the long straights. 
 
The next meeting was the Prix Martime in Germany held as a road event followed by two races on the little Travering circuit outside Hamburg.   The road event was supposed to be on closed roads but I was not a little surprised to have a farm cat lumber out in front of me when doing in excess of 100mph.   This may have been the reason I misjudged the next corner and put the car in the ditch.  All this with the intrepid  Gerald sitting beside me.  We did not stop but the nearside front wheel had to be changed later.

The first evening was also the time for the drivers briefing for the next days racing and the lady in charge was also driving her Bugatti in our race.   As usual I had several questions and afterwards I was backed into a corner – “Herr Sutton you ask too many qvestions”.  We were convinced she wore leather underwear!

Sutton_Merc_Targa_Florio_S.jpgA huge crowd had turned out to see the Mercedes race as it is a very rare care and to my knowledge one had never before raced in Germany.   The entries were very mixed with modern and vintage cars on this very twisting circuit with little humps over which the Mercedes “took off”.   On the second lap the throttle jammed wide open as I lifted off to take the corner before the grandstand.   It is amazing how quickly one finds the ignition switch in such circumstances!   After negotiating the corner with a dead engine I got to thinking about all those enthusiasts who had come to watch and the many others who we were told would be watching on TV, so I switched the ignition on again and surged into the next corner steering with one hand and the other hovering over the switch.   After I while I got the hang of this new method of driving with full throttle or nothing and actually won the race lapping a 4.2-litre E Type Jaguar on the way!   The Bugatti lady was decidedly un-amused, but the free beer afterwards was memorable!
 
There were other races and Prescott hillclimb.   I had tried in vain to persuade Gerald to let me fix the blower so that for this type of event it was permanently engaged no matter what the throttle opening, but he would have none of it.   Readers may imagine the difficulty of judging the timing with so little distance between these very tight corners.  Of course I overdid it going into the semi-circle and lifted off and spun clockwise over the edge onto the rapidly sloping grass.  The car went up on two wheels and I thought it was going to roll all the way down the hill, but I managed to move my weight far enough across the car to bring it down on its wheels again!   The marshals emerged clapping “well held”.   Fortunately Gerald could not make practice that day and the car only ingested some grass through the blower so I did not give a detailed report.  It did however stick in my memory!  We won the class on the day!
