Rare Rides Icons: The Cadillac Eldorado, Distinctly Luxurious (Part LXIV)

In our previous installment, Cadillac introduced the tenth generation Eldorado coupe of 1979. The new car was smaller in all dimensions, 900 pounds lighter, and wore very different styling to its predecessor. The changeup was necessary, as Eldorado ventured into a PLC market fundamentally different to the one the enormous and boaty ninth-gen Eldorado occupied between 1971 and 1978. For the second time in its history Eldorado was a clean break design, and attempted to return to the sharp angles and simple lines it wore in 1967.


(Note: The 1978 Eldorado is two-tone brown, and a Custom Biarritz Classic. The 1979 in black is a standard model with Cabriolet vinyl, while the light gray example is a basic trim. The white one is a Biarritz.)

Modernization was the most prevalent insistence of the new design. Gone were the heavy square egg crate texture from the grille, the chunky chrome bezels for the headlamp surrounds, and the amber turning indicators. In their place was a finer grille texture with horizontally oriented egg crate, simply framed quad rectangular headlamps, and Euro-style clear indicator lamps.


The grille itself was much narrower than the prior year, as the car was several inches narrower and had less real estate to offer. Eldorado block lettering was removed, as the grille was ensconced in chrome trim with a Cadillac script logo at top right. The bumper was a simpler looking design than the prior year and got away with two vertical bumper guards at either side of the license plate, instead of six separate guards in 1978.


Front fenders were still tall and creased, but protruded less from the body than they did in 1978, both in overall height and in forward reach. The shield decorations from the front corners were mercifully eliminated in 1979, as were the grandiose faux extensions in length given by the front clip. The line for the front clip assembly was still visible and wore individualized styling to differentiate the Eldorado from the Toronado.


The fenders were no longer tapered at the top to form a supplemental character line but fell off almost vertically down the side and left a smooth surface. The corner marker lamp and indicator were moved further forward ahead of the wheel. The wheel arch itself now wore a lip and was no longer a flat surface. Arches cut down closer around the wheel and left much less empty space behind each tire.


Block lettering that vanished from the Eldorado’s flank in 1977 returned as an Eldorado script in 1979, with a badge advertising the electronic fuel injection (a badge Cadillac maintained into the 1990s). Side mirrors were the same shape as before but mounted on a much shorter stalk that also contained an optional exterior thermometer. Above was a more relaxed A-pillar, as the Eldorado leaned into fuel economy and modern aero styling and shed its upright formal 1970s look.


Also less formal was the side window arrangement, where frameless glass met with a rear side window just behind the door shut line. That window did not roll down, which meant the Eldorado was not a true pillarless hardtop. Few customers missed the thickly padded opera window, and if they did the Continental Mark V was still there for them in their time of need.


The flanks of the Eldorado reflected minimal decoration. The chrome trim spear was gone, replaced with nothing. As with past Eldorados, there was a strip of chrome along the rocker panels and fender bottoms that served to length the car visually. Three wheel choices were offered for Eldorado: a base chromed wheel disc (rare), a finned alloy that looked sportier (fairly rare), or chromed faux wire wheels (most common).


Aft of the rear side window was a thick B-pillar that ended at an upright notchback roof. It cut off sharply at the sloped rear deck, and the Eldorado no longer featured its trademark upward kick behind the door. The look was sleek when finished in metal. However, there were vinyl roof coverings available in the “Cabriolet” option package, and it was standard on the Biarritz.


Other exterior changes with Biarritz were a script badge on the B-pillar that replaced the Cadillac logo, along with an opera lamp on either side. Following the lead set by the 1977 Biarritz trim, a chrome spear began at the front of the fender. It got thicker and more substantial until it covered the lower portion of the windowsill entirely, and headed upward across the B-pillar in a more substantial way than regular Eldorados. This feature was a callback to the 1955 Eldorado’s window treatment.

Biarritz continued with the visual glitz. It included as standard a stainless steel roof panel exclusive to the trim. Unpainted, the stainless had a brushed finish and was trimmed at either end by a thick piece of chrome. The Biarritz most often featured some contrast pinstriping to add to the overall effect.


Past the vinyl (or not) roof treatment was a simplified rear end that removed most of the excess of the 1978 Eldorado. The trunk lid had a simple crease down the middle where it met with the Cadillac logo, and all curvaceous bloat was gone. The trunk was no longer tiered, but cut down sharply in line with the rear tailfins that were smaller than ever. Fenders were simple and clean and no longer wore a red reflector.


Lamps were simplified too and no longer had chunky chrome tailfin housing. Simple red vertical spears were thin and delicate looking and no longer sheltered by chrome caves. Lower rear bumper spears were gone altogether, replaced with a curved chrome bumper that mimicked the design at the front. Simple badging at the back said Eldorado on standard models, and included a block letter Diesel badge underneath if the car was cursed with that engine. Biarritz examples said so on the back, to let onlookers know it was the special trim package.


Overall, the Eldorado wore its looks very well in 1979. It was a new era of Eldorado design which coincided with a leadership change at GM styling. One of the last great designs to slip through the net, the changeup was orchestrated by the board at GM and would lead to one of the worst product eras in the company’s history. We’ll delve into that context and the plush new interior of the Eldorado next time.

Interested in lots of cars and their various historical contexts. Started writing articles for TTAC in late 2016, when my first posts were QOTDs. From there I started a few new series like Rare Rides, Buy/Drive/Burn, Abandoned History, and most recently Rare Rides Icons. Operating from a home base in Cincinnati, Ohio, a relative auto journalist dead zone. Many of my articles are prompted by something I'll see on social media that sparks my interest and causes me to research. Finding articles and information from the early days of the internet and beyond that covers the little details lost to time: trim packages, color and wheel choices, interior fabrics. Beyond those, I'm fascinated by automotive industry experiments, both failures and successes. Lately I've taken an interest in AI, and generating "what if" type images for car models long dead. Reincarnating a modern Toyota Paseo, Lincoln Mark IX, or Isuzu Trooper through a text prompt is fun. Fun to post them on Twitter too, and watch people overreact. To that end, the social media I use most is Twitter, @CoreyLewis86. I also contribute pieces for Forbes Wheels and Forbes Home.

    My dad was a Cadillac guy. Always Coupe DeVille’s until my mom saw an Eldorado in a parking lot. He went out that next week and came home with a shiny new 1985 Eldorado Biarritz white with red leather. The car was beautiful. My personal favorite is the 77/78 years.

    I Love my 1977 Cadillac Eldorado Baritz all original I'm the 2nd owner and have the original receipt bought in December 1976

  • Vid169489471 The technology exists today to produce a variable color temperature (kelvin) LED lamp. It can vary from 2700k that soft orange look to 6500k the bright daylight with the bluish tint.Since everything in a late model car is computer controlled, it would be an easy task to write a few lines of code that enables your vehicle to not only dim down from hi to low beam but to shift color temp down to the 2700k range for oncoming traffic, then back up to 5000k once oncoming traffic has passed. For the operator it would be automatic and seamless. For older cars they could be retrofitted with LEDs that are 2700k on low beam and 5000k on hi beam. As far as standards, there could be a lumens max, and a minimum. Several States already have minimum lumen standards going back to the old incandescent bulbs. Why not update these to national standards.
  • Jam169859557 More regulation is needed for ALL vehicle lighting systems. [list=1][*]The lighting that is most blinding are the rapidly flashing red, blue and amber lights on emergency vehicles. The lights themselves are blinding, flashing so rapidly that it's impossible for even the sharpest eyes to adjust. What's worse, is the nature of the emergency requires a careful view of the area surrounding the emergency vehicle. There is something going on that needs to be seen. More flashing lights is not the solution.[/*][*]Brighter headlights need to be regulated. The tall riding vehicles do not need headlights positioned so high that they blind drivers in lower riding vehicles. And those heasdlights need to be aimed properly. When I first started driving my 2020 Subaru Outback, many drivers would flash their lights, hoping I would dim my lights. This stopped after I performed am easy adjustment that tilted the beam lower. Late model Subaru headlamps are designed with a sharp cutoff that project less glare above the hood line. When the headlights are properly aimed, other drivers are not blinded by the beam.[/*][*]Customized light assemblies make it more difficult to see the marker lights (tail lamps, turn signals and side marker lamps) that have been tinted. There are many municiple codes that prohibit this tinting, but these laws are seldom enforced.[/*][/list=1]Solutions: Tight controls on emergency vehicle lighting. In trying to make these vehicles more visible, a dangerous side effect is reducing the ability of drivers to see the surrounding perils.Headlight design regulations that reduce the height of the headlight assemblies. Just because a pickup truck has a hood that sits 4 feet abouve the pavement, it does not mean the headlights need to be so high. Owneres should maintain proper adjustments to their vehicle headlights.Establish and enforce regulation requiring a illumination standard be followed.
  • Stl170698708 as someone who hates big government, and their interference;but you can add me to the list of people that are blinded by the lights.unfortunately "the poop is out of the horse and no way is it going back in"They have had 5 years to make lights bigger, badder and brighter because in the vehicle work it is go big or go home!Trucks are the worst because so many people use them to express their dominance and that is big, big, big $$ both at the Original Purchase and in the Aftermarket world.If, we are so lucky to get some good government regulation on this it will also take some very good Court enforcement to get the aftermarket people with fines and lawsuits.Much like the EPA did with the Diesel Tuner Industry that felt emission regulations didn't apply to them.This is from someone that owns said pickup truck with the same bright headlights,but i only use the truck when I have too and always turn off the Fog lights when driving in traffic.
  • Art65765977 I saw a porsche 911 with the most amazing headlights from behind approaching the Sunshine skyway in Florida. The pattern was 108 degrees across sweeping the road like a broom. My brother and I were amazed. I don't know what it looked like from the front but i am sure it was better than American cars
