Lamborghini Jarama: which version to buy
There is only one catalogue version of the Lamborghini Jarama to buy: 3.9 MT. The model ran as 1 generation from 1970-03-01 to 1976-12-31, only as a Coupe, with 1 listed modification. That version is a Gasoline 12-cylinder V-shaped engine, 3929 cm³, 365 hp and 407 Nm, Manual 5-speed, RWD, No boost, kerb weight 1540 kg, 0–100 km/h in 6 s, top speed 260 km/h.

Fuel use, tank size, CO2, eco class and wheel sizes are not measured. Extra money cannot buy a second engine, a later restyle as a separate generation, or another gearbox in this dataset — arithmetic below is all on 3.9 MT.
Jarama specs: the only version on the sheet
People searching “Jarama specs” or “which Jarama to buy” are comparing a field of one. 3.9 MT is the full list.
| Version | hp | Nm | Displacement, cm³ | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 3.9 MT | 365 | 407 | 3929 | Gasoline | 12 | V-shaped | No | Manual | RWD |
3.9 MT is Gasoline, not a second fuel type. Cylinders are 12, layout V-shaped, valves per cylinder 2, boost No. Engine position is Front, longitudinal. Feed is Carburetor. Compression ratio is 10.7. Bore and stroke are 82 × 62. The listed fuel grade is 92. Gearbox is Manual with 5 gears. Drive is RWD. Front and rear suspension are both Independent, spring. Front and rear brakes are both Disc.
There is no second row to subtract from the first. A buyer who wants more gears, AWD, a smaller engine, or boost is not choosing inside this model: those columns do not change because they exist only once.
Engine: 365 hp from 3929 cm³ on 3.9 MT
Power of 3.9 MT is 365 hp (268 kW) at 7500 rpm. Torque is 407 Nm at 5500 rpm. Displacement is 3929 cm³.
Power per litre on 3.9 MT is 365 / 3.929 ≈ 92.9 hp per litre. Torque per litre is 407 / 3.929 ≈ 103.6 Nm per litre. Peak power sits 2000 rpm above peak torque (7500 − 5500). That gap is a fact of this one calibration, not a comparison between two tunes.
No boost means the 365 hp and 407 Nm are the naturally aspirated figures in the data. There is no supercharged or turbo row with a higher hp figure to “buy up to.” Carburetor is the only fuel system listed; there is no injection variant name in the catalogue.
12 cylinders in a V-shaped layout with 2 valves per cylinder is 24 valves in total (12 × 2). Compression 10.7 and bore × stroke 82 × 62 belong to this same 3.9 MT engine. Short stroke relative to bore is in the millimetres given (62 vs 82); it is not a second engine.
If two versions had shared the name 3.9 MT, they would be split by horsepower. They do not: one name, 365 hp.
Performance and mpg: what 3.9 MT actually posts
0–100 km/h for 3.9 MT is 6 s. Top speed is 260 km/h.
Kerb-weight power is 365 / 1540 ≈ 0.237 hp per kg, or 1540 / 365 ≈ 4.22 kg per hp. That is the only power-to-weight ratio in the model. Gross weight 1890 kg against 365 hp is 1890 / 365 ≈ 5.18 kg per hp when loaded to the rated maximum.
City consumption is not measured. Highway consumption is not measured. Combined consumption is not measured. MPG searches do not get a number from this sheet; writing a guessed L/100 km would be a number that is not in the data.
CO2 is not measured. Eco class is not measured. Those blanks are not “Euro something” inferred from the 1970-03-01 start date.
6 s to 100 km/h and 260 km/h are the performance pair you actually purchase with 3.9 MT. There is no slower automatic and no hotter special in the modification list to trade against that pair.
Dimensions, weight and clearance: 3.9 MT as a buy
Kerb weight of 3.9 MT is 1540 kg. Gross weight is 1890 kg. Payload implied by those two figures is 1890 − 1540 = 350 kg. Ground clearance is 115 mm. Fuel tank is not measured. Wheel sizes are not measured.
115 mm clearance is the ride-height number for the Coupe; there is no second generation with a different clearance to prefer. Tank capacity cannot be used to choose a touring spec because it is not measured. Wheel size cannot be used to choose a tyre package because it is not measured.
Weight is the lever that exists: 1540 kg kerb under 365 hp. A heavier hypothetical twin is not listed. The 350 kg between kerb and gross is the load band on the same Independent, spring axles and Disc brakes, not a different chassis code.
Generations: 1 generation, nothing later to “step up” to
1 generation ran 1970-03-01 to 1976-12-31, body Coupe, 1 version. Restyling is not a separate generation in this data, so there is no “facelift Jarama” row with different hp, kg or gearbox.
A generation-to-generation buy decision needs two start/stop pairs and two spec tables. Here the later pair does not exist. Buying “the last generation” and buying 3.9 MT are the same purchase: production ends 1976-12-31 on that one modification.
Years in production for this generation span from March 1970 through December 1976 on the dates given. That is one window, not a first series and a second series with their own modifikaciy counts.
Which version to choose
Choose 3.9 MT because it is the only version. The numbers that justify that choice are the only numbers on the car:
- 365 hp and 407 Nm from 3929 cm³ Gasoline, 12 cylinders, V-shaped, No boost, Carburetor, Front, longitudinal.
- Manual 5 and RWD — no automatic and no other drive to pay extra for.
- 6 s to 100 km/h, 260 km/h, 1540 kg kerb, ≈ 4.22 kg/hp, ≈ 92.9 hp/L.
- 1890 kg gross, 350 kg implied payload, 115 mm clearance.
- City / highway / combined fuel, tank, CO2, eco class, wheels: all not measured, so they cannot break a tie that does not exist.
What extra money does not buy inside this catalogue: more hp than 365, more Nm than 407, another displacement than 3929, a gearbox other than Manual 5, drive other than RWD, a body other than Coupe, or a second generation after 1976-12-31.
Reliability and “problems” are not in the launch data; they are not used as a reason to pick one row over another. Prices are not in the data; “what the extra money buys” is only the arithmetic gap between listed specs, and with one spec that gap is zero.
3.9 MT is the Jarama you specify. Every figure above sits on that name.
