Porsche 959 specs and what the one version actually is
Because no second version exists in the data, there is no “cheaper 959,” no “later restyle,” and no “more powerful 959” to trade up to. Extra money cannot buy extra horsepower inside this catalogue. The buying question collapses to: do these measured figures match what you need, and do the not-measured fields (fuel use, tank, emissions) leave too large a gap for your use case.
2.9 MT is a Gasoline Coupe with a Rear 6-cylinder Opposite engine, Turbo, Distributed injection (multi-point), Manual 6-speed gearbox, and RWD. Rated output is 450 hp (331 kW) at 6500 rpm and 500 Nm at 5500 rpm from 2850 cm³. Compression ratio is 8.3. Bore and stroke are 95 × 67. Fuel grade is 98. Claimed 0–100 is 3.9 s and top speed is 310. Kerb weight is 1450 kg; gross weight is 1770 kg; ground clearance is 120. Wheels are 235/45 R17 and 275/40 R17. City, highway, and combined consumption are not measured. Tank size is not measured. CO2 is not measured. Eco class is not measured.

Generations: what changed, and what did not
1 generation (1986-01-01 – 1991-12-31)
1 generation ran from 1986-01-01 to 1991-12-31 as a Coupe with 1 version: 2.9 MT. No restyling generation is listed, so there is no mid-cycle body or power jump to hunt for. Production window length from the given dates is 1986 through 1991 inclusive — six calendar years of the same named specification. Year-to-year shoppers are not choosing a different engine or a different drive layout in this dataset; they are choosing a build year of the same 2.9 MT.
If you hoped a later 959 generation would add an Automatic, AWD, a larger tank figure, or a measured mpg number, this catalogue does not contain that later generation. The generation count is 1. The version count inside it is 1. Arithmetic between generations is therefore zero change: power stays 450 hp, torque stays 500 Nm, displacement stays 2850 cm³, kerb weight stays 1450 kg, 0–100 stays 3.9 s, top speed stays 310.
Engine and specs table (the only version)
| Version | Years | hp / kW @ rpm | Nm @ rpm | cm³ | Fuel | Cylinders / layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 2.9 MT | 1986-01-01 – 1991-12-31 | 450 / 331 @ 6500 | 500 @ 5500 | 2850 | Gasoline, 98 | 6, Opposite, 4 valves per cylinder, Rear | Turbo | Manual, 6 | RWD |
Specific output from the given numbers: 450 hp ÷ 2.850 L = 157.9 hp per litre. In kW: 331 ÷ 2.850 = 116.1 kW per litre. Torque per litre: 500 ÷ 2.850 = 175.4 Nm per litre. Those ratios are the entire “engine choice”: there is no naturally aspirated sibling and no larger-displacement sibling to undercut or beat them.
Turbo is the only boost type listed. Compression 8.3 sits with that Turbo rating; there is no second compression figure to compare. Fuel is 98 only — there is no 95-grade version in the data, so you cannot buy a lower-octane 959 here.
Valves: 4 per cylinder × 6 cylinders = 24 valves on 2.9 MT. Layout label in the data is Opposite, not a format invented outside the record. Engine position is Rear. Injection is Distributed injection (multi-point). All of those are fixed; none can be optioned away inside this catalogue.
Performance and economy: 0–100, top speed, mpg
2.9 MT 0–100 is 3.9 s. Top speed is 310.
City consumption: not measured. Highway consumption: not measured. Combined consumption (the figure people search as mpg): not measured. CO2: not measured. Eco class: not measured.
A buyer who needs a documented mpg or emissions number cannot extract one from this catalogue for any 959 version, because only 2.9 MT exists and those fields are empty. Choosing “the economical 959” is not possible here; there is no second version with a lower (or any) consumption figure.
Power-to-weight from kerb mass: 1450 kg ÷ 450 hp = 3.22 kg per hp, or 450 ÷ 1450 = 0.310 hp per kg. Per tonne: 450 ÷ 1.450 = 310.3 hp per tonne. Torque-to-weight: 500 Nm ÷ 1450 kg = 0.345 Nm per kg, or 500 ÷ 1.450 = 344.8 Nm per tonne.
If 0–100 of 3.9 s is the buying threshold, this is the only number on offer. If 310 top speed is more than you will use, you still cannot buy a slower, lighter-tuned 959 in these data — the catalogue does not list a detuned 2.9 MT.
Peak power rpm is 6500; peak torque rpm is 5500. The gap is 1000 rpm. There is no second engine map to compare that spread against.
Dimensions, weight, wheels, tank
Kerb weight 2.9 MT: 1450 kg. Gross weight: 1770 kg. Payload by subtraction: 1770 − 1450 = 320 kg. Payload as a share of kerb: 320 ÷ 1450 = 22.1%. Ground clearance: 120. Tank: not measured. Wheel sizes listed: 235/45 R17 and 275/40 R17.
Front suspension: Independent, spring. Rear suspension: Independent, spring. Front brakes: Ventilated disc. Rear brakes: Disc.
A buyer comparing “which 959 is lighter” has no second kerb figure. 1450 kg is the only kerb weight. A buyer comparing ground clearance across generations has one value: 120. A buyer who needs a known tank size before a trip cannot get it from this record; it is not measured, and skipping that sentence would look as if a 959 has no tank field.
Two wheel sizes are given, not one: 235/45 R17 and 275/40 R17. The catalogue does not label which axle is which; it lists both as the wheel set for 2.9 MT. There is no 16-inch or 18-inch alternative version.
Which version to choose
Choose 2.9 MT if you want the Porsche 959 that this catalogue actually contains: 450 hp, 331 kW, 500 Nm, 2850 cm³ Gasoline Turbo, Rear 6-cylinder Opposite, Manual 6, RWD, Coupe, 1450 kg kerb, 3.9 s to 100, 310 top speed, 120 ground clearance, 98 fuel, compression 8.3.
You cannot choose another version because `modifikaciy` is 1. There is no second row to pick by horsepower (no twin nameplates at different hp), no Automatic, no other drive label, and no other generation. Arithmetic between versions is undefined: the difference in hp is 450 − 450 = 0; the difference in Nm is 0; the difference in kg is 0.
What “extra money” would buy, using only these numbers: nothing inside the model line. Extra money cannot buy more than 450 hp, more than 500 Nm, a shorter 0–100 than 3.9 s, or a higher top speed than 310, because those peaks already belong to the sole version. Extra money also cannot buy a measured combined consumption figure; that field is empty.
What you are buying, stated as ratios so a pulled paragraph stays true for 2.9 MT:
- 157.9 hp per litre from 2850 cm³ and 450 hp
- 175.4 Nm per litre from 2850 cm³ and 500 Nm
- 3.22 kg per hp from 1450 kg and 450 hp
- 310.3 hp per tonne
- 320 kg between 1770 kg gross and 1450 kg kerb
- 1000 rpm between 5500 Nm peak and 6500 hp peak
- 24 valves from 6 cylinders × 4 valves per cylinder
Reliability and problems: this dataset does not measure failure rates, so reliability is not measured. Do not treat silence as “no problems.” The buying filter that is in the data is specification match: Manual 6 and RWD and Turbo Gasoline 450 hp, or not this car.
If the search is “Porsche 959 specs,” “Porsche 959 engine,” “Porsche 959 0-100,” “Porsche 959 dimensions,” or “which Porsche 959 to buy,” the answer from this catalogue is one sentence that stays true alone: 2.9 MT is the only version, 1986-01-01 to 1991-12-31, Coupe, 450 hp / 500 Nm / 2850 cm³, Manual 6, RWD, 1450 kg, 3.9 s, 310 top speed, consumption and tank not measured.
