Engine Variants

B18B and B18D, The early P1800 Jensen and 1800S models used the 1.8-litre B18 four-cylinder. The B18D featured twin SU carburettors and made around 95-115 hp depending on tune. These are shared with the Amazon and are known for high mileage capability. Not fast by any measure, but durable. The B18 can develop a characteristic “dip” in revs at idle when worn, if it runs too smoothly, it’s likely tired.

B20A and B20B, From around 1969, the 1800E received the 2.0-litre B20B with twin Zenith-Stromberg carburettors, producing roughly 114 hp. More torque than the B18, still carburetted. Parts are widely available and these engines are bulletproof if maintained.

B20E and B20F, The later 1800E and all 1800ES models got Bosch D-Jetronic fuel injection. The B20E made around 118-130 hp. More power, smoother delivery, but injection parts (injectors, air pressure sensors, fuel controllers) are getting rare and expensive. The B20F is mechanically similar to the B20E.

All P1800 engines are understressed and overbuilt. 250,000 miles is normal if you keep up with oil changes. Weeping oil from the front cover or rear main seal is common, not a disaster, just something to live with or fix during a timing belt service.

Transmission Options

4-speed manual with overdrive, This is the one you want. The M40 or M41 gearbox with a Laycock D-type or J-type overdrive. The overdrive can have electrical or hydraulic gremlins (cutting in and out, not engaging), but nine times out of ten it’s something simple. The hydraulic system needs clean fluid and proper adjustment.

4-speed manual, Less common, no overdrive. Makes the car feel slower on the motorway.

BW35 3-speed automatic, Rare. Saps power noticeably and makes the car feel sluggish. If you find one with an auto, it’s either a very late 1800E or an oddball. The manual is vastly preferable.

Notable Features

• Safety focus: Volvo’s first sports car still prioritised occupant protection. Strong passenger cell, crumple zones for the era.
• Designed for distance: Comfortable seats (especially in later 1800E/ES models), good visibility, low-stress cruising character.
• Durable mechanicals: Shared parts with Amazon, 140, and 164 models. High parts interchangeability across the range.
• Pop-up headlights: The original design (by John de Vries for Volvo Netherlands) had fixed lights, but US regulations required a specific height. Flip-up lights were the solution, though they weren’t needed by the time the car launched. Kept them anyway, looked cool.
• The Saint: Roger Moore’s TV car. Helped sell the P1800 in export markets, particularly the UK and US.
• Glass tailgate on 1800ES: Inspired by the 1800ES’s spiritual predecessor, the 1800ES shooting brake, which took design cues from the earlier Volvo 1800ES concept.
• Volvo’s first million-seller ambitions: While the 240 eventually became Volvo’s first true million-seller, the P1800 project was part of the Galaxy Project that aimed to make Volvo a serious volume player.
