A new look with hidden headlamps and block letters on the hood
|
On September 22, 1965 Buick introduced a completely new
Riviera. The 1966 model was two inches longer and has a four-inch wider
tread than the previous year, due to the new frame designed to improve
the ride and handling. The new body featured a longer hood and fenders,
a more sloping windshield and modified fastback roof and deck. Car Life
magazine voted it the "handsomest car of 1966", noting that
there wasn't much wrong esthetically with the '65 version. "Where
earlier models had elegant plain lines, the new version has sweeping,
swooping, swinging lines with definite fender top and hood profiles." |
The design for the '66 was attributed to Buick's chief
designer Dave Holls. Holls had moved around GM working also with Chevrolet
and Cadillac where his designs influenced the '59 Cadillac, 60's Corvettes,
67-70 Camaro and '70 Monte Carlo. He retired in 1991, but keep very
active in the old car hobby. He passed away in June 0f 2000. |
The new design received high praise from many automobile
magazines for it's handling and flowing style. Most noticeable was the
absence of the window vents, which were made unnecessary with the introduction
of "Circulaire" a new ventilation system. Fresh air is taken
into the car through a grille in the hood, just in front of the windshield
and is exhausted though a similar grille under the rear window. Tests
had shown that this system would keep the interior of the car comfortable
in 70-degree plus temperatures without having to open a window. In keeping
with the disappearing headlamp feature inaugurated in '65 the '66 headlamps
are concealed above the radiator grille. When the headlamp switch is
turned on, the lights swing down into position in front of the grille. |
The headlamps folded up under the hood when not in use.
This car also has turning lamps and new wire hubcaps.

Notice the new taillights and one-piece bumper.

The grille is composed of nine thin horizontal bars, which extends into
the parking lights located in the fenders. The name "Riviera"
appears in block letters on the front edge of the hood. The horizontal
bar design is carried over into the long taillights, which are surrounded
by silver painted trim. Buick offered eight standard paint colors and
seven "exclusive Riviera colors." They also doubled the amount
of colors available for a vinyl roof to black or white, since only black
was offered in '65. Based on our research only 7.2% of the buyers selected
the vinyl top option. Besides the standard hubcap, a very stylish wire
cap with a spinner was offered, as well as the option chrome wheel.
The center cap on the chrome wheel was changed to a ribbed cone shape.
All of the caps and wheels had a black center with a silver stylized
"R".
|
The interior had a whole new look and for the first time
a bench seat was available in a Riviera. In fact for the standard interior
you had a choice of either a bench or bucket front seat. The bench was
available in blue, black or dove vinyl, while the bucket was offered
only in black vinyl. The door on the standard trim was quite plain with
a small arm rest and a small-brushed aluminum panel. Those who paid
extra for the optional interior were treated to a larger variety of
colors as well as one of the most stylist door panels found in any car.
All of the optional seats had a back called "Strato", which
in effect was the same style used on the bucket seats. The optional
bench seats all had a pull down center armrest. The all vinyl bench
was offered in red, blue, green white or black. The cloth and vinyl
bench was offered in blue, black or plum. The optional bucket seats
were offered in blue, aqua, black or dove vinyl. The buckets could be
ordered with either a short storage console or a full wood trimmed console
with a floor shift. Headrests were offered for the first time and available
on either the bench or buckets. Once again the simulated wood wheel
was offered as an option. The dash was exclusive to the Riviera, which
had an unusual floating drum speedometer and gauges rather than warning
lights. Offered for the first time were automatic climate control and
a stereo AM/FM radio. |

A new cruciform frame was designed to accommodate the
longer wheelbase along with an improved front and rear suspension. The
rear suspension was redesigned by moving the springs from the lower
control arms to the axle to effect greater control over "squat'
on acceleration and lift during braking. Although it shared the same
"E-body" frame with the Toronado, it remained a rear wheel
drive, despite speculation that it might also convert to front wheel.
The only engine offered was the 425ci, 340 hp, code "MW",
with a single 4 bbl Quadra-jet carburetor. Initially the GS package
included a single carburetor with a chrome air cleaner, with the aluminum
valve covers, heavy-duty suspension, posi-tracion, 3.42 rear axle, whitewalls
or red line tires and GS monograms on the fenders and on the glove box.
Until March of '66 the dual four option was only available as a dealer
option, after which it could be ordered from the factory and had a "MZ"
engine code.
