According to the latest files to hand, this year’s
racing motor cars will present fewer novelties than
ever before. Transmission by propeller-shaft is gain-
ing in favour every day over chain drive, and all the
machines are being built with their centre of gravity
placed very low. One peculiarity which the new regu-
lations at home have engendered is that all cars will
have a large fuel capacity, provision being made for
as much as 45 gallons of petrol, and a proportionately
large oil supply, in order to cover the six rounds of
the circuit without stopping to fill tanks. Excepting
the Mercedes, and of course the six-cylinder Napier, it
is probable that all the starters will have four-cylinder
engines. The Richard Brasier cars, with four cylinders
of 165-m.m. bore, and 104 h.p., will have transmission
by cardon shaft. The Mercedes six-cylinder have 150-
m.m. bore, and 140-m.m. stroke, giving 135 h.p., four
speeds, with direct drive on the high, and ball bear-
ings throughout. Several of the French drivers have
already made acquaintance with the circuit, Hemery
visiting it on a 1905 racer immediately before his
triumphal return from Florida.
