"THE AUTOCAR " SUBSCRIPTION RA TES :

The eavy L,:1;~~~!:ce.

\Ve a re pleased to announce that a race on Tourist Trophy lines, but for a bigger type of car, is to be held by the .-\utomobile Club. It will not take place on the same day as the race for the Tourist Trophy , I.Jut it will be run o ff during the same week. T o avoid confusion between the two races we would draw particul a r attention to th e title of th e new event- the Heavy Touring Car Race. It is already dubbed ,the " Ton T.T. " and the" Heavy T.T., " but it is rea ll y better to leave the Tourist Trophy severely alone so far as the tit le of the new race is concerned, because there is only one Tourist Trophy, and that is raced for by cars of a lighter t ype than those which will engage in the heavy car ra ce .

The new event is a supplement to th e old one--that is to say, the Tourist T rophy Race "·ill r emain the rri terion of the moderate powered , medium sized ca r.

,rhile the Heavy Touring Car Race will become the extreme test for the larger sized motor carriage, not the absolute monster car, but a big, powerful machine which is fu ll y up to the task of making a telling average uphill , ove r hea vy road s, and against the wi nd, as well as under easy conditions, with a .commodious touring limousine body and a full complement of passengers and baggage. Each - chassis is to carry one ton, as compared with the 12 ¾ . cwt. which the Tourist Trophy cars have to take. T he fue l limit is sixteen mil es to the gallon, which, it is computed, will enable . cats with engines of 45 h.p. to take ri art. What will actually be the limit in this direction is unsafe to prophesy, beca use the sizes of engines used in the Tourist Trophy Race have astounded the majority of those who would have said that ,vith such a fuel limit it would have been impossible to employ engines as large as those which won or perform e,J prominently in Tourist Trophy Races. Iii any case, there is little doubt th at, despite the bigger load, th,: heavy touring cars will make higher averages than those performed in the Tourist Trophy Race. Indeed, it is a very great question whether the heavy tourin g cars should not be cont~olled over the more dangerou ;; section of the mountain road between the summit of Snaefell and Willaston, because there are so , man, places on this road where passing on the smaller car~ is too risky. However, this is a matter which can be tested in practice, because after all the heavy car, will sit the road better than the lighter T . T . cars, an d as their overall width is not necessarily any greater. passing may not be so serious a matter as many imagine it will be upon this section of the course.

There are great objections to attempting any contro l. because it could scarcely be done in such a way as to give equa l chances to all competitors. That is to say. if every car was kept at the summit of Snaefol l til l such time as the secti on was signalled clear it woul d mean tha t some machines would have to wait ver r much longer than others, and as they could not afford to run their engines while waiting, they would have to stop them, and th at would result in some of th e engines which had the long waits getting much colder tha n those which were kept for a short time .

It will be the first race in which an attempt has been made to ensure that the cars shall offer approxi matelv th e same resistance to the ai r as ordinar v tour ing c~rs. There have been pl enty of competitions in which big touring bodies have been insisted upon , but th ese events have not actually been races , and tlw 8ft. x .5ft. 3in. screen -, for the heavy touring r:i.ce ll'ill certainly make th at portion of the work devoted t novercoming a ir resistance very heavy. The load. too . of one ton , all of it dead load except the driver anrl° his a ss is ta nt, is a tremendous one even in these _ da rs . of hea vy limousines . Probably no chassis will wei/i-h much les s than 17 cwts ., and many considerably mo re. so that the test in tyres will be a very severe one; in, fact, th e race as a whole will be a very severe test· indeed. The fuel limit itself is hard enough 1rl w11,
