Alpine A310: which version to buy

The Alpine A310 buying choice is one generation, one Coupe body, five factory versions, all on sale in the data from 1971-01-01 to 1985-12-31. There is no second generation to jump to, so the decision is arithmetic between 1.6 MT (125 hp), 1.6 MT (127 hp), 1.7 MT (95 hp), 2.7 MT (150 hp) and 2.9 MT (193 hp).

The Alpine A310 buying choice is one generation, one Coupe body, five factory versions, all on sale in the data from 1971-01-01 to 1985-12-31. There is no second generation to jump to, so the decision is arithmetic between 1.6 MT (125 hp), 1.6 MT (127 hp), 1.7 MT (95 hp), 2.7 MT (150 hp) and 2.9 MT (193 hp). Every listed version is Gasoline, naturally aspirated (boost: No), Manual with 5 gears, RWD, independent spring suspension front and rear, Disc brakes at both ends, and a 55 L tank. What changes is displacement, cylinder count, layout, fuel system, power, kerb weight, and — for one version only — a measured top speed.

If the question is “which Alpine A310 to buy,” the short answer from the numbers: 2.9 MT is the most powerful (193 hp / 142 kW); 2.7 MT is the only version with a measured top speed (220 km/h) and the best measured weight-to-power among versions that list a kerb weight (6.53 kg/hp); the two 1.6 MT cars are the most power-dense four-cylinders (about 78–79 hp per litre) at 840 kg; 1.7 MT is the lightest (825 kg) but the weakest (95 hp). Prices are not in this dataset.

Generations: what the only generation actually offers

1 generation (1971-01-01 to 1985-12-31) is the entire Alpine A310 catalogue here: Coupe, five versions. There is no restyling generation and no later A310 generation in the data, so you cannot “buy the later generation” of this model. You can only buy a different engine and fuel-system combination inside the same years and the same body.

That matters for a used-car decision: year span is shared (all five versions carry the same start and stop dates in the data), body is shared (Coupe), drivetrain layout is shared (RWD Manual 5). The generation does not change kerb-weight class by itself — weight tracks the engine, not a new chassis generation. The four-cylinder cars sit at 825–840 kg; the 2.7 MT six sits at 980 kg, 140 kg heavier than either 1.6 MT and 155 kg heavier than 1.7 MT. 2.9 MT kerb weight is not measured, so you cannot rank that version on weight-to-power.

Alpine A310 specs: engines compared version by version

Exact names as in the database. Two versions share the name 1.6 MT and must be split by power.

Torque (Nm) is not measured on any Alpine A310 version in this set. Peak power rpm is 6000 on four versions and not measured on 1.6 MT (127 hp).

Alpine A310 engine: four-cylinder vs V-shaped six

The engine split is the real buy filter.

Four-cylinder, Inline, 4, Gasoline, boost No:

• 1.6 MT (125 hp): 1605 cc, Carburetor, 125 hp / 92 kW at 6000 rpm.
• 1.6 MT (127 hp): 1605 cc, Distributed injection (multi-point), 127 hp / 93 kW; rpm not measured.
• 1.7 MT: 1647 cc, Carburetor, 95 hp / 70 kW at 6000 rpm.

Six-cylinder, V-shaped, 6, Gasoline, boost No:

• 2.7 MT: 2664 cc, Carburetor, 150 hp / 110 kW at 6000 rpm.
• 2.9 MT: 2849 cc, Carburetor, 193 hp / 142 kW at 6000 rpm.

There is no turbo version in this data. A search for “Alpine A310 V6 turbo specs” does not match any listed modification: boost is No on all five.

Horsepower per litre (specific output)

Using displacement in litres from the table:

• 1.6 MT (125 hp): 125 / 1.605 = 77.9 hp/L
• 1.6 MT (127 hp): 127 / 1.605 = 79.1 hp/L — highest in the catalogue
• 1.7 MT: 95 / 1.647 = 57.7 hp/L
• 2.7 MT: 150 / 2.664 = 56.3 hp/L — lowest
• 2.9 MT: 193 / 2.849 = 67.7 hp/L

The two 1.6 MT versions extract more power from each litre than either six. The 2.7 MT six is the least power-dense: it buys displacement, not specific output. 2.9 MT recovers some density versus 2.7 MT (67.7 vs 56.3 hp/L) while adding 43 hp (193 − 150) on 185 cc more (2849 − 2664).

What the extra displacement buys

• 1.7 MT vs 1.6 MT (125 hp): +42 cc (1647 − 1605) and −30 hp (95 − 125). The larger four-cylinder is not the stronger four-cylinder.
• 1.6 MT (127 hp) vs 1.6 MT (125 hp): same 1605 cc, +2 hp / +1 kW, and the fuel system changes from Carburetor to Distributed injection (multi-point). That is the smallest power step in the line.
• 2.7 MT vs 1.6 MT (127 hp): +1059 cc, +2 cylinders (6 vs 4), layout V-shaped instead of Inline, +23 hp (150 − 127) and +17 kW (110 − 93).
• 2.7 MT vs 1.7 MT: +1017 cc, +55 hp (150 − 95), +40 kW (110 − 70).
• 2.9 MT vs 2.7 MT: +185 cc, same 6 V-shaped Carburetor layout, +43 hp (193 − 150), +32 kW (142 − 110).
• 2.9 MT vs 1.7 MT: +98 hp (193 − 95) — the full spread of the catalogue.
• 2.9 MT vs 1.6 MT (125 hp): +68 hp (193 − 125).

If “Alpine A310 V6” is the search, the data contains two V-shaped sixes: 2.7 MT and 2.9 MT. There is no separate “V6 GT” or “Pack GT” row in this catalogue.

Performance and economy: what is measured

0–100 km/h is not measured for 1.6 MT (125 hp), 1.6 MT (127 hp), 1.7 MT, 2.7 MT, and 2.9 MT.

Top speed:

• 2.7 MT: 220 km/h — the only measured figure
• 1.6 MT (125 hp): not measured
• 1.6 MT (127 hp): not measured
• 1.7 MT: not measured
• 2.9 MT: not measured

Fuel consumption (city, highway, combined) is not measured on all five. CO2 is not measured. Eco class is not measured. MPG is therefore not a number you can use to pick a version from this dataset.

You cannot rank 0–100 between versions. You can rank top speed only as “2.7 MT is the one with a published 220 km/h; the others are not measured,” not as “2.9 MT is slower.” 2.9 MT has 43 hp more than 2.7 MT, but its top speed is not measured here.

Alpine A310 weight and dimensions

Kerb weight (measured):

Dimensions (length, width, height, wheelbase) are not measured for any version. Wheel sizes are not measured. Ground clearance is not measured. Gross weight is not measured. Tank is 55 L on every version — range cannot be calculated because consumption is not measured.

Weight per horsepower

• 1.6 MT (125 hp): 840 / 125 = 6.72 kg/hp
• 1.6 MT (127 hp): 840 / 127 = 6.61 kg/hp
• 1.7 MT: 825 / 95 = 8.68 kg/hp — worst among measured weights
• 2.7 MT: 980 / 150 = 6.53 kg/hp — best among measured weights
• 2.9 MT: kerb weight not measured, so kg/hp is not measured

1.7 MT is 15 kg lighter than either 1.6 MT (825 vs 840) but carries 30 hp less than 1.6 MT (125 hp) and 32 hp less than 1.6 MT (127 hp). Lightest is not the best weight-to-power.

2.7 MT adds 140 kg versus 1.6 MT and 155 kg versus 1.7 MT. Against 1.6 MT (127 hp) that extra 140 kg buys 23 hp and improves kg/hp from 6.61 to 6.53 — a 0.08 kg/hp gain. Against 1.7 MT the same 155 kg buys 55 hp and cuts kg/hp from 8.68 to 6.53.

Chassis hardware does not differentiate versions: Independent, spring front; Independent, spring rear; Disc front; Disc rear; RWD; Manual 5; 55 L tank. You are not buying a different suspension or brake type when you move from 1.7 MT to 2.9 MT.

Which Alpine A310 version to choose

Use the numbers. There is one generation, so this is not a generation choice.

Choose 1.7 MT if the priority is lowest listed kerb weight (825 kg). It is the lightest Alpine A310 in the data. It is also the weakest: 95 hp / 70 kW, 57.7 hp/L, 8.68 kg/hp. Versus 1.6 MT (125 hp) you give up 30 hp to save 15 kg. Versus 2.7 MT you give up 55 hp and 220 km/h of measured top speed to save 155 kg. Fuel system is Carburetor. Buy this only if mass, not power, is the filter.

Choose 1.6 MT (125 hp) if you want the stronger Carburetor four-cylinder. Same 1605 cc, Inline 4, Gasoline, boost No, 840 kg, Manual 5, RWD as the injected twin, but Carburetor and 125 hp / 92 kW at 6000 rpm. Specific output 77.9 hp/L is second only to the 127 hp car. Versus 1.7 MT: −42 cc, +30 hp, +15 kg. Versus 2.7 MT: −1059 cc, −25 hp (125 vs 150), −140 kg, and no measured top speed.

Choose 1.6 MT (127 hp) if you want the four-cylinder with Distributed injection (multi-point) and the highest hp/L in the catalogue (79.1). Same 1605 cc and 840 kg as 1.6 MT (125 hp); the step is +2 hp / +1 kW and a different fuel system. Peak rpm is not measured on this version. Torque is not measured. This is the smallest numerical upgrade in the line; it is not a different displacement and not a different weight.

Choose 2.7 MT if you want the only version with a measured top speed (220 km/h) and the best measured kg/hp (6.53). Engine: 2664 cc, 6, V-shaped, Gasoline, Carburetor, boost No, 150 hp / 110 kW at 6000 rpm. Kerb weight 980 kg. Versus 1.6 MT (127 hp): +23 hp, +140 kg. Versus 2.9 MT: −43 hp, but 2.9 MT has no measured top speed and no measured kerb weight, so 2.7 MT is the six you can actually score on speed and mass. If “Alpine A310 V6 specs” means a complete measured row, this is the complete six.

Choose 2.9 MT if peak horsepower is the only filter. 193 hp / 142 kW at 6000 rpm, 2849 cc, 6, V-shaped, Gasoline, Carburetor, boost No, Manual 5, RWD. That is 43 hp more than 2.7 MT and 98 hp more than 1.7 MT. Kerb weight is not measured, 0–100 is not measured, top speed is not measured, torque is not measured. You cannot claim it is the lightest six or the fastest six from this data — only the most powerful.

What you do not get to choose from this catalogue

• No Automatic, no extra gear counts: every version is Manual 5.
• No AWD or FWD: every version is RWD.
• No diesel, no turbo: every version is Gasoline, boost No.
• No second body: Coupe only.
• No second generation: 1 generation only, 1971-01-01 to 1985-12-31.
• No GT / Pack GT / turbo V6 row.
• No price, no “for sale” stock, no USA/UK/Australia/Canada listing data.
• Alpine A310 vs A610, vs Porsche 911, vs GTA: those rival models are not in this dataset, so they are not scored here.
• Problems and reliability: not measured in this dataset for any version. You cannot rank 1.6 MT Carburetor against 1.6 MT Distributed injection (multi-point) on failure rate from these numbers.

A compact decision order

1. Need a measured top speed → 2.7 MT (220 km/h); others not measured. 2. Need maximum listed horsepower → 2.9 MT (193 hp / 142 kW). 3. Need best measured kg/hp → 2.7 MT (6.53), then 1.6 MT 127 hp (6.61), then 1.6 MT 125 hp (6.72); 1.7 MT is 8.68; 2.9 MT not measured. 4. Need highest hp per litre → 1.6 MT 127 hp (79.1), then 1.6 MT 125 hp (77.9), then 2.9 MT (67.7). 5. Need lowest kerb weight → 1.7 MT (825 kg), then both 1.6 MT (840 kg), then 2.7 MT (980 kg); 2.9 MT not measured. 6. Need multi-point injection rather than Carburetor → only 1.6 MT (127 hp). 7. Need a V-shaped 6 → 2.7 MT or 2.9 MT; all others are Inline 4.

That is the whole Alpine A310 choice set in this catalogue: five named versions, one Coupe generation, and the gaps (Nm, 0–100, mpg, dimensions, wheels, clearance, gross weight, 2.9 MT mass, reliability) marked as not measured rather than assumed.
