CHEVROLET MOTOR COMPANY
PRESENTS IT'S NEW MODELS

beautiful combinations on the sov
en- models.
The Imperial Landau is finished
in Cossack brown Duco with Noun
tain brown beading and gold strip
ing; the Coupe and Sedan in Faunce
green Duco with black body bead
ing and stripping in golden yellow;
the sport cabriolct in Dundee gray
Duco with Rrocatelle green Duco
beading and gold stripe; the coach
in Avenue green Duco, Tartan tan
wheels, black beading and stripping
iii gold; and the open touring and
roadster in Falmouth gray Duco
with body beading in black and
stripping in French gray.
Mechanically the car has been i'm
proved to parallel in performance,
speed and roadability its new and
advanced body design. 1t is pow
cred by an improved valve-in-head
engine that in road tests developed
34.6 percent more power and ap-
1roXimately five more miles per
hour than the previous Chevrolet
engine.
New features developed in the en-
which completely covers the valve
lifts and makes for a quieter and
cleaner engine, new crankcase
breathing system which eliminates
the leakage of engine fumes
through the body of the car; new
two-port exhaust; new alloy con-
slant clearance "invar strut pis-
tons, new hydro-laminated camshatt
gears, improved mushroom valve
tappets, and larger camshaft
An oil pump provides efficient
fabrication to all bearing surfaces; !;
while an AC oil filter and an AC
air cleaner protect all moving parts
q; the eYgine from dirt and other
foreign matter, thus adding mater
iaily to the life of the motor.
Four Wheel Brakes
The new four-w brakes rep
resent an outstanding achievement
Il General Motors and Chevrolet
engineers. They are the non-lock
ing type, with positive brake link,
age.
Front brakes are internal eg-
panding and rear brakes external
contracting. Front and rear brakes
lave been proportional to prevent
side drag or pull. Their total brak
ing surface amounts to lS9 square
inches.
Each brake has an individual
easily accessible adjustment. while
stops are provided at the wheels
to simplify the adjustment opera
tion. So accurately has the lever
age on the foot pedal been worked
1ut between the front and Pear
irakes that maximum application of
the brakes is obtained with a very
Slight pedal pressure.
In addition to the four wheel
brakes the new ears have an emer-
gencv brake, with an additional
raking surface Of 20 square inches.
It operates entirely independent of
the four wheel service brakes, thus
assuring adequate braking facili-
ties at all times.
Another important achievement
in the 1928 line is the new shock
;,5sorber scmi-clliptic springs which
run parallel to the frame and equal
s. percent of the increased wheel
base of the ear. The springs rep
resent still another innovation pio-
ncered by Chevrolet engineers.
They provide 80 percent better
riding qualities than the old type
spring, according to observers.
In developing the new springs,
Chevrolet engineers strove not only
FOR smooth boulevard driving but
also for maximum comfort at high
speeds over rough roads.
This end could be attained, they
discovered after exhaustive testing
dhd experimenting, through increas-
ing spring friction by putting re-
verse "chccks' two to each spring
midway between the center
Shackle and the spring end. These
"'checks resemble inverted steel
bows with the center section press
cd down against the top spring leaf
Lnder 600 pounds of pressure.
Electric System Safe
The new models have a slender
- inch walnut finished steering
wheel, while increased steering ease
has been attained by the inclusion
CT several new features. Ball bear
ing thrusts have been added to the
steering mechanism, and the steer
ing ratio has been increased from
eight to nine and onc-half to one.
Transmission, universal joint and
rear axle are of the dependable con
stTuction that gave such satisfac
tory service in the "MoSt Beautiful
Chevrolet,' as is the electrical
system. An index of the safety of
the electrical equipment and the
approved vacuum feed type of syS-
tom with safety tank in the rear, is
the fact that underwater s approx
al gives the lowest fire insurance
races.
The chassis, in addition to its
four inch ncredse in length, has
Il new extra strong front axle. The
frame is of channel steel 3-4
inches deep, with five rigid steel
cross members.
Stewart vacuum fuel feed has
