London, Dec. l9.-tNEA)-When
Major H. o. D. Segravc returned 20
England last March with his record
average OF 23l.4 miles an hour. 1t was
generally believed that this vas
about the ultimate speed man could
attain on land.
His special racer had SKINNED over
tho measured mile. both with and
against the wind, along the Daytona
Beach in Florida not much slower
than the special airplane OF the Brit
isll victor, H. r. d. Waghorn. who
won the Schneider cup race last sep
tcrlbcr with a speed Of 320.6 miles an
hour. This Is the fastest speed man
has ever attained by any means.
Now however, The Autocar, British
auto magazine. reveals . much more
powerful racing automobile Is being
built at the Sunbeam factory with
which 1t is hoped Kaye Don. another
famed British driver, will raise MAJOR
Segrave's record BY . considerable
margin.
The new racer which will take ia
the DaytOna Beach sands sometime
between March ! and IS, Is unique IN
MANY respects. It Is q 1000 horse.
mower affair. with two l?-cylinder
engines mounted tandem and = sep
aratc drive for each rear wheel. II Is
built to the measurements OF IL
driver. its chassis and body measuring
only two feet six inches across. II,
has. however. q wheelbAse Of IS feet
and its wheels reach out from the
narrow body to q width Of five feet.
BODY Goods Water
The entire car Is encased within 9
shell, above and below. so that II Wal
float IL 1t happens to be driven into
the sea. Instead OF . radiator It has
4 double shell within which the water
flows to be cooled.
nespite the cars size and the i'm.
menstty Of the engines, the entire
affair weighs only two and . hall
tons. which affords the reu1araoly
low ration Of IL pounds Of weight g
the horsepower.
What occasions this low weight =
the use Of aluminium for body and
engine blocks. the cylinders lined by
the new nttralloy steel. This steel
has : high degree Of hardness and 2
smooth glass-like surface. and IN
creases the power Of the engines from
10 to Is per cent. The ptstons. 700
are OF forged aluminium.
Nitralloy steel also conposes the
material Of the seven bearing crank
shafts, while aluminium = used .

chargers, one to each engine. What
is called ! "lay-shatt" runs the length

There are two water pumps, one

three oil pumps keep the OIL circu-

shafts, other moving parts ana
through the crankcase.
Head Resistance Lowered
Perhaps most novel Of MI features
jn this racer is the way frontal area
has been reduced in order to decrease
the cars head resistance. According
to Louis Coatalen. Sunbeam engineer.
who is building this car, 05 per cent
of the cars tremendous power has TO
be spent overcoming head resistance
while the remaining five per cent =
taken UP by FRACTIONAL resistance.
Reduction Of head resistance Is q.
tanned by the use Of two propeller
shafts. one for each wheel, 50 that
the driver can be set low between
them, rather than high above the
conventional single shaft. At the
same time there Is no need Tor .
I~iifferential.
The shafts are driven by means Of
\ multiple disc clutch and through
the regular three.speed transmission.
but the clutch Is locked positively 70
the crankshaft Is soon - the car
rcts into motion. The propeller
shafts turn up 1000 revolutions .
minute with the motors running
1T 1000.
In order to assure good visibility
tor the driver, the seat has been
sprung Independently Of the chassis
by means Of = countegweight equal
TO the weight Of Don Kaye himself.
This is expected to keep him steady
ct even the highest speed.
