Sainted Swede: The Volvo P1800 and 1800ES

FROM P1800 TO 1800S

Early P1800 sales were modest, averaging around 2,700 units a year — well below Jensen’s ultimate capacity. Nonetheless, the publicity the coupe generated probably contributed to Volvo’s continuing robust growth. By the end of 1962, annual automobile production had reached nearly 80,000 units, prompting Volvo to expand production with new plants in Torslanda (west of Gothenburg) and the Belgian town of Alsemberg.

The additional capacity meant that Volvo now had room to bring P1800 production in-house, which they were more than ready to do. Volvo engineers remained dissatisfied with Jensen’s quality control and Gunnar Engellau can’t have been pleased by press reports that the P1800’s workmanship didn’t meet Volvo’s customary standards. In early 1963, P1800 production was transferred to Volvo’s Lundby plant, even though the move obliged Volvo to pay Jensen an early termination fee; the British company had so far built only 6,000 of the 10,000 units originally contracted. Pressed Steel would continue to produce the body stampings through 1969, but Volvo would now assemble the cars itself.

The B18B engine now had 10.0:1 compression (up from 9.5), a hotter ‘C’ camshaft, and stiffer valve springs, raising output to 108 gross hp SAE (81 kW) and 110 lb-ft (149 N-m of torque.

The initial Lundby-built cars were little changed, but for the 1964 model year, Volvo made a host of minor changes to address previous quality complaints. Visible changes of the new models, known internally as model D, were limited to “1800S” badges, new wheel covers, amber turn signal lenses, new seats, revised upholstery, and proper (if still tiny) folding rear seats. Under the hood, the 1800S was up to 108 gross horsepower (81 kW), maintaining its advantage over the 122S sedan, which was now available with a 90 hp (67 kW) single-carburetor version of the same engine. These improvements were welcome, but they weren’t free. Swedish cars were up to 21,000 SEK (about $4,050), U.S. models to $3,995 POE. (In the U.K., base prices were up commensurately, but a reduction in purchase tax rates actually lowered the out-the-door cost by a nominal £11.)

Some period tests describe these cars as “P-1800 S,” but the question of whether the P prefix was still correct for Swedish-built cars still arouses the same sort of controversy as calling a Jaguar E-type an “XKE.” Volvo apparently used the P internally on at least some occasions, but we don’t believe the cars were registered that way, nor have we seen any marketing materials using the “P-1800 S” or “P-1800 E” designations.

Over the next five years, the Volvo 1800S underwent the sort of gradual evolution familiar to Porsche and Volkswagen owners. For the 1965 model year, the distinctive ‘cow horn’ front bumpers were replaced by a simpler horizontal unit, perhaps as a cost-saving measure, allowing front and rear bumpers to share the same tooling. The 1966 models, introduced in August 1965, brought a new grille, a brake proportioning valve (to delay rear lockup in hard stops), and more power: now 115 gross horsepower (86 kW) and 112 lb-ft (151 N-m). (Net output was up to 103 hp DIN (76 kW).) The extra power trimmed 0-60 mph (0-97 km/h) times to less than 12 seconds and increased top speed to around 110 mph (160 km/h), more competitive with cars like the MGB. The 1967 models, meanwhile, updated the car’s nose with a more complex aluminum grille and replaced the curved ‘hockey stick’ body side trim with straight chrome strips.

If that wasn’t enough, in 1966, Volvo dealers introduced a performance kit for the B18 engine based on the competition package developed for the Amazon. The kit included a new cylinder head with bigger valves and 11.0:1 compression, a lightened flywheel, a new cam, re-jetted carburetors, and a new tubular steel exhaust manifold. The changes were good for a claimed 135 hp SAE (101 kW), which provided much better performance with little sacrifice in drivability. However, with a price tag of $299 plus installation, the kit was an expensive addition to an already expensive car. We don’t know if many were sold.

For the 1969 models, known internally as model S, Volvo bored out the B18 engine from 84.14 mm to 88.90 mm (3.31 to 3.50 inches), increasing displacement to 1,986 cc (121 cu. in.). The new B20B, as the engine was called, was otherwise little different than the B18B, although the compression ratio was lowered half a point, to 9.5:1, and the oil cooler was deleted; Volvo concluded that improvements in motor oil had made it unnecessary. Power was up only slightly, to 118 gross horsepower SAE (88 kW), or 105 net horsepower DIN (77 kW), but torque improved by about 10%, from 112 lb-ft (151 N-m) to 123 lb-ft (166 N-m). Other useful additions were an alternator, replacing the previous generator, and Volvo’s unusual 3×2 dual-circuit brake system, which ensured that both front brakes and at least one rear brake would work if one circuit were lost.

The Volvo P1800 and 1800S were well-appointed for their era, with very comfortable seats and leather/vinyl upholstery, but the high cowl and beltline made the cabin a trifle claustrophobic. Ventilation was never great and with no glove box, interior storage was skimpy. One interesting feature was three-point seat belts, something Volvo had pioneered in 1959. Three-point harnesses were nominally standard from the beginning of production, but obscure regulatory issues initially forced their deletion in some U.S. markets.

The 1800S was never a runaway sales success, but it found a unique niche, abetted by its television exploits (see the sidebar above). The coupe sold well through the middle of the decade, typically accounting for around 4,500 units a year. By 1968, however, sales were slipping, falling to a disappointing 1,693 units for 1969. Performance had never been outstanding to begin with and the 1800S was increasingly pressed by cheaper rivals like the MGB GT. To survive, the 1800 would need more extensive changes.

The dash of the Volvo P1800 and 1800S was attractive, but many period reviewers criticized it as a triumph of style over function. The gauges between the tachometer and speedometer are for water and oil temperature; the three pods to the right of the wheel are the fuel gauge, oil pressure gauges, and clock. On early cars, the overdrive was controlled by a toggle switch on the dash, which on LHD cars was immediately to the left of the ashtray. On the 1800S, Volvo moved it to the right-hand steering column stalk, which had previously controlled the second horn for highway passing. (Photo © 2011 Tyler Brand; used with permission)

  1. There was also the 123GT, a 122 with the mechanicals of a P1800. I don’t have the impression that Volvo made many of them, or sent many to the States.

    There used to be an immaculate 123GT parked near my work in Seattle in the mid-1980s. It had the Federally mandated side marker lights, so presumably it dated from the end of the 122’s life. In the early 2000s I was in stop-and-go traffic and saw a 123GT, which may or may not have been the same one, in the next lane. I rolled down my window, the other guy rolled down his, and I yelled, “Nice 123GT!”

    Did anyone produce any aftermarket bits to address the 1800ES’s handling flaws?

    1. I haven’t investigated the 123GT in any detail, but I think it was introduced in 1967. In other markets, it appears it was available through 1970, the end of Amazon production, but at least one source says the two-door models were all dropped in the U.S. at the end of the 1968 model year, so that would make all U.S. cars ’67 or ’68 models. (I shot some not very good photos of one back in December.)

      Since the suspension of the 1800ES was nearly, if not completely identical to that of the 1800E/1800S, which in turn was very similar to that of the Amazon, I would imagine that a lot of the competition pieces developed for the latter would probably fit without too much trouble. The trick, as always, is figuring out a combination that would produce a net improvement in handling without just wrecking the ride or making it tail happy. Based on the complaints of contemporary reviewers, it sounds like greater front roll stiffness and firmer damping might be in order. I assume there are Volvo clubs and mailing lists with folks who have experience with modifying these cars who would be able to speak with more authority as to what works and what doesn’t.

  2. WOW!

    Really, that’s about all I can say is “wow”. It seems like every time you do an article on an automaker you’ve never done before you take it upon yourself to unearth their entire history. Just [i]look[/i] at that source list, incredible! The thoroughness of the research and the skill with which it is integrated into the article is, as usual, second to none. I am continually blown away by the quality of your work. I seriously think that you could base a very respectable college history course on nothing other than your body of work on this website. Just amazing. Please do keep it up! These articles are the highlight of my month in terms of internet reading material.

  3. Just for clarification, the overdrive units name was Laycock de Normanville, not the other way around. Great article as usual Aaron. Brought back a lot of great memories of working on them back in the 70s and 80s. Except for that goofy air cleaner behind the grille. Getting that bloody thing out and back in was like a Chinese block puzzle.

  4. Very interesting as always Aaron, I am a fan of the 1800ES, and it was also great to see the write-up on the shooting brakes in the sidebar.

  5. I love my car, and I have loved them since 1975 but just recently bought one. Yes it is not he best driving car I have ever driven, but I think it is the Coolest car I have ever driven. Being a Swedish American, eventually I had to get one of these cars. It has been my favorite car since I sat in one in Southern Calif. at a Volvo dealer. They feel so good.Thx Volvo

  6. I never really understood how the P1800 kind of became a success, while the P1900 didn’t. Apparently both models have their flaws. Funnily, some people are willing to pay more than $100.000 for the P1900 (check out this: parabeam. nl/ article/ car-history-%E2%82%AC-94500-fiberglass-model).

    1. Well, the P1900 was a much cruder effort, even in Volvo’s own estimation, and Volvo judged that it would ultimately be better to develop a new, better car than to try to fix the P1900’s flaws. It wasn’t that the P1900 was a commercial failure, but that Gunnar Engellau decided, “We can do better than this,” and pulled the P1900 from the market very quickly. The P1800 wasn’t perfect and it was pricey for its performance, but it was a credible offering and much more of a Volvo in the sense of robustness and usability. The likely reason the P1900 is worth more as a collectible is simply that it’s comparatively novel (a lot of people have never heard of the P1900, much less seen one) and exceptionally rare, not because it was an intrinsically better car than the P1800 — which I don’t think even the few P1900 owners would claim.

  7. I am the original owner of a 1970 Volvo 1800E. I am restoring the interior. I’m having difficulty wiring the 3 way interior light switch under the dash on the driver’s side. Does anyone out there know how this switch should be wired or know of someone that does. If so, please return this comment.

    1. I’m afraid I’m not qualified to help with repair or restoration advice, sorry!

    2. I realize this is an old thread, perhaps someone can help. Trying to remove the combined water/old temp gauge on my 1968 1800S. How does one disconnect the metal tubes in the back that connect the the engine sending units?thank you

      1. I’m sorry, I’m not able (or qualified!) to provide repair or maintenance advice!

  8. As the owner of both a Jensen Healey (not GT) and a Volvo 1800ES, I particularly enjoyed this article. The 1800ES is a joy to drive in modern 2016 traffic and it turns heads wherever it goes. It is a efficient, dependable classic with the most dependable engine ever build (See Irv Gordon Guiness record) which was designed by Italians in the vein of 1950’s Ferraris. Really you could not do much better than that.

  9. As a matter of linguistic interest, the definite article is suffixed onto the noun in Swedish, Danish, and Norwegian. Strictly speaking, raket = “rocket,” and raketen = “the rocket.” This also occurs in Romanian and Bulgarian. The fancy linguistic term for a suffixed definite article is an enclitic.

    1. I did not know that! I’ve attempted to reflect that in the text just now.

  10. Yes, I know that this is an old thread.

    Incredibly well done and remarkably sourced. Nice job!
