Engine Variants

B18A (1967-1968): Carburetted 1.8L four-cylinder, 75 hp. The slowest of the bunch. Adequate for city use but struggles on the highway. Not the engine you want if you’re planning to use this car daily in modern traffic.

B18B (1967-1968): Higher-compression version of the B18A, 90 hp. Slightly quicker but still not thrilling.

B20A (1969-1970): Carburetted 2.0L, 82 hp. More torque than the B18, makes the car feel livelier. Much better for overtaking.

B20B (1971-1974): Lower-compression 2.0L, 88 hp. Introduced for stricter emissions in some markets. The most common engine in later cars.

B20D (1971-1972): Higher-output carburetted 2.0L, around 100 hp. Brief run, replaced by the B20B.

B20E (1971-1974): Bosch D-Jetronic fuel injection, 118 hp. The one to have if you want performance. K-Jetronic system was introduced late in 1974. Injection parts are getting harder to find, especially for D-Jetronic. Ask if the system’s been converted or if original parts are still available.

The B20E is the sweet spot, plenty of torque, more reliable fuelling than carbs in varying conditions, and enough poke to keep up with traffic. If you see a B20E car, jump on it.

Transmission Options

M40 4-speed manual: Standard box. Nothing fancy, but robust. Gear lever is long until 1972, when it was shortened.

M41 4-speed + overdrive: Laycock overdrive unit on fourth gear. Electrically and hydraulically actuated. Can be temperamental, check for proper engagement and disengagement. If it’s popping out of overdrive or not engaging at all, could be electrical (often a simple switch or relay) or hydraulic (more annoying). Still, the overdrive makes the car much more relaxed on the highway.

BW35 3-speed automatic: Borg-Warner torque converter automatic. Saps power noticeably, making even the B20E feel sluggish. Reliable if maintained, but expect higher fuel consumption and slower acceleration.

The M41 with overdrive is the enthusiast’s choice. The M40 is fine if you don’t mind revving out third gear on the motorway. Avoid the automatic unless you absolutely need it, these cars aren’t quick to begin with.

Notable Features

For the era, the 140-series was a safety benchmark:

• Dual-circuit braking system: If one circuit fails, 80% braking power remains (mostly at the front). A massive improvement over single-circuit systems in the PV444 and early Amazons.
• Disc brakes all around: Standard from 1966. Makes the car stop predictably and reduces fade.
• Crumple zones front and rear: Absorbs impact energy. Body structure is stiff where it needs to be.
• Collapsing steering column: Reduces chest injuries in a frontal impact.
• Reinforced door locks and bars in doors (1973+): Better side-impact protection.
• Padded dashboard (1973+): New dash with round instruments, less likely to injure occupants.
• Excellent seats: Volvo’s reputation for supportive, long-distance-friendly seating starts here. Even the base-spec seats are good.

Other practical details:

• Headrests standard from 1970: Important for whiplash protection.
• Heated rear window from 1970: Standard across the range.
• Hazard lights from 1970: Obvious in hindsight, but not universal at the time.
• 145 wagon with split tailgate (early models) or single tailgate: Huge cargo capacity, especially the 145 Express with its raised roof.
• Simple, durable mechanicals: Designed to be serviced with basic tools. Parts are cheap and widely available.

These cars weren’t bought for speed or flash. They were bought because they worked, kept their occupants safe, and lasted forever if you kept the rust at bay.
