VAZ 2106: which version to buy
The VAZ 2106 is a Sedan sold in one generation from 1976-01-01 to 2006-12-31. The catalogue lists three versions — 2106 1.6 MT, 21061 1.5 MT, and 21063 1.3 MT — all Gasoline, Carburetor, 4-speed Manual, RWD. The choice is not between generations (there is only one) and not between body types (Sedan only). It is between three displacements: 1569 cm³, 1452 cm³, and 1294 cm³.
The VAZ 2106 is a Sedan sold in one generation from 1976-01-01 to 2006-12-31. The catalogue lists three versions — 2106 1.6 MT, 21061 1.5 MT, and 21063 1.3 MT — all Gasoline, Carburetor, 4-speed Manual, RWD. The choice is not between generations (there is only one) and not between body types (Sedan only). It is between three displacements: 1569 cm³, 1452 cm³, and 1294 cm³. The extra displacement buys 10 hp and 22 Nm versus the smallest engine, 10 km/h of top speed, and two seconds off 0–100, at the cost of 1.5 L/100 km more combined fuel than 21063 1.3 MT.
Generations: one generation, three versions
1 generation (1976-01-01 to 2006-12-31) is a Sedan with 3 versions. All three share the same production window, so a later year does not mean a later generation. There is no restyling generation in the data. What changed between versions is engine size, power, torque, mass, and fuel use — not layout, gearbox, or drive.
VAZ 2106 specs: engines compared
| Version | hp (kW @ rpm) | Nm @ rpm | cm³ | Fuel | Cylinders / layout | Valves / cyl | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 2106 1.6 MT | 74 (53 @ 5000) | 116 @ 3000 | 1569 | Gasoline, 92 | 4, Inline | 2 | not measured | Manual, 4 | RWD |
| 21061 1.5 MT | 72 (52 @ 5600) | 106 @ 3500 | 1452 | Gasoline, 92 | 4, Inline | 2 | not measured | Manual, 4 | RWD |
| 21063 1.3 MT | 64 (47 @ 5600) | 94 @ 3400 | 1294 | Gasoline, 92 | 4, Inline | 2 | not measured | Manual, 4 | RWD |
Shared hardware you do not get extra money for: Front, longitudinal engine, Carburetor, compression 8.5, Independent, spring front / Dependent, spring rear, Disc front / Drum rear, 39 L tank, 170 mm clearance, wheels 165/70 R13 or 175/70 R13.
Power per litre (hp ÷ displacement in litres): 21061 1.5 MT 49.6 hp/L, 21063 1.3 MT 49.5 hp/L, 2106 1.6 MT 47.2 hp/L. The 1.5 is the densest; the 1.6 is the strongest in absolute terms, not the most efficient per cubic centimetre.
Bore × stroke: 2106 1.6 MT 79 × 80, 21061 1.5 MT 76 × 80, 21063 1.3 MT 79 × 66. The 1.6 and 1.5 share an 80 mm stroke; the 1.3 cuts stroke to 66 mm and loses 275 cm³ versus the 1.6 (1569 − 1294). The 1.5 is 117 cm³ smaller than the 1.6 (1569 − 1452) by a 3 mm narrower bore.
Peak power rpm: 2106 1.6 MT at 5000, both smaller engines at 5600. Peak torque rpm: 3000 / 3500 / 3400. The 1.6 makes its 116 Nm 500 rpm earlier than the 1.5 and 400 rpm earlier than the 1.3.
Performance, mpg, and what the extra power buys
| Version | 0–100 | Top speed | City | Highway | Combined | CO2 | Eco class |
|---|---|---|---|---|---|---|---|
| 2106 1.6 MT | 16 s | 155 | 10.3 | 7.4 | 10.1 | not measured | not measured |
| 21061 1.5 MT | 16 s | 150 | 9.8 | 7.4 | 10.0 | not measured | not measured |
| 21063 1.3 MT | 18 s | 145 | 9.5 | 7.8 | 8.6 | not measured | not measured |
0–100: 2106 1.6 MT and 21061 1.5 MT are equal at 16 s. 21063 1.3 MT is 2 s slower (18 s). Two extra horsepower on the 1.6 versus the 1.5 (74 vs 72) do not change the 0–100 figure in this dataset.
Top speed: 155 / 150 / 145. Each step down in displacement costs 5 km/h. The 1.6 is 10 km/h faster than the 1.3 (155 − 145).
Fuel: Combined, 21063 1.3 MT at 8.6 L/100 km is 1.5 L/100 km below 2106 1.6 MT (10.1) and 1.4 below 21061 1.5 MT (10.0). City: 9.5 / 9.8 / 10.3 — the 1.3 is 0.8 L/100 km better than the 1.6. Highway is the exception: 21063 1.3 MT uses 7.8, while both larger engines use 7.4. If most kilometres are highway, the 1.3 is not the thriftiest; it is 0.4 L/100 km worse than the other two.
On a 39 L tank, combined range in litres-per-tank arithmetic: 39 ÷ 10.1 × 100 ≈ 386 km for 2106 1.6 MT, 39 ÷ 10.0 × 100 = 390 km for 21061 1.5 MT, 39 ÷ 8.6 × 100 ≈ 453 km for 21063 1.3 MT. That is about 67 km more tank range for the 1.3 versus the 1.6 (453 − 386). Highway-only: 39 ÷ 7.4 × 100 ≈ 527 km for 1.6 and 1.5, versus 39 ÷ 7.8 × 100 ≈ 500 km for the 1.3 — the highway penalty reverses the ranking.
CO2 and eco class: not measured on all three.
Dimensions, weight, and kg per horsepower
| Version | Kerb | Gross | Payload (gross − kerb) | Clearance | Tank | Wheels |
|---|---|---|---|---|---|---|
| 2106 1.6 MT | 1045 kg | 1445 kg | 400 kg | 170 mm | 39 L | 165/70 R13, 175/70 R13 |
| 21061 1.5 MT | 1035 kg | 1435 kg | 400 kg | 170 mm | 39 L | 165/70 R13, 175/70 R13 |
| 21063 1.3 MT | 1045 kg | 1445 kg | 400 kg | 170 mm | 39 L | 165/70 R13, 175/70 R13 |
Payload is 400 kg on every version. Clearance, tank, and wheel sizes do not differ. 21061 1.5 MT is the lightest kerb mass: 10 kg under the other two (1035 vs 1045).
kg per hp (kerb ÷ hp): 2106 1.6 MT 14.1 kg/hp (1045 ÷ 74), 21061 1.5 MT 14.4 kg/hp (1035 ÷ 72), 21063 1.3 MT 16.3 kg/hp (1045 ÷ 64). The 1.3 carries 2.2 kg more per horsepower than the 1.6 (16.3 − 14.1). That lines up with the 2 s slower 0–100.
Torque per tonne (Nm ÷ kerb tonnes): 2106 1.6 MT 111 Nm/t (116 ÷ 1.045), 21061 1.5 MT 102 Nm/t (106 ÷ 1.035), 21063 1.3 MT 90 Nm/t (94 ÷ 1.045). The 1.6 has 21 Nm/t more than the 1.3 (111 − 90).
Which version to choose
There is no second generation to “wait for.” Chassis, gearbox, drive, brakes, suspension, tank, clearance, and wheels are the same. The decision is engine.
Buy 2106 1.6 MT if you want the strongest numbers in this catalogue. It is 74 hp and 116 Nm from 1569 cm³, 0–100 in 16 s, 155 km/h. Versus 21063 1.3 MT that is +10 hp (+15.6% on 64), +22 Nm (+23.4% on 94), +10 km/h, −2 s to 100. Versus 21061 1.5 MT the gaps are small: +2 hp, +10 Nm, +5 km/h, and the same 16 s 0–100. You pay 10.1 combined versus 10.0 on the 1.5 and 8.6 on the 1.3. Peak torque arrives at 3000 rpm, the lowest of the three. Power per litre is the weakest of the three (47.2 hp/L), so you are buying capacity, not specific output.
Buy 21061 1.5 MT if you want nearly the 1.6’s pace at 10 kg less kerb mass. 72 hp and 106 Nm, 16 s to 100, 150 km/h, 1035 kg. Combined 10.0 is 0.1 L/100 km under the 1.6 and 1.4 above the 1.3. City 9.8 sits between 10.3 and 9.5. Highway matches the 1.6 at 7.4. Specific output is the highest (49.6 hp/L). You give up 5 km/h and 10 Nm versus 2106 1.6 MT and keep the same 0–100. If the question is “what does 117 cm³ extra on the 1.6 buy versus this 1.5,” the data’s answer is 2 hp, 10 Nm, 5 km/h, and no 0–100 change.
Buy 21063 1.3 MT if combined fuel and tank range matter more than 0–100. 64 hp, 94 Nm, 18 s, 145 km/h, combined 8.6. Versus the 1.6 you lose 10 hp, 22 Nm, 10 km/h, and 2 s, and you gain 1.5 L/100 km combined and about 67 km of combined tank range. City 9.5 is the best of the three. Do not pick it for highway mpg: 7.8 is worse than 7.4 on both larger engines. kg/hp is the heaviest (16.3). Stroke 66 mm versus 80 mm on the other two is the geometric reason it is 1294 cm³, not a different chassis.
What extra money cannot buy here (no prices in the data, only spec gaps): a different gearbox (all Manual, 4), a different drive (all RWD), boost (not measured on all), a different body, a later generation, measured CO2, or a measured eco class. Wheels and 170 mm clearance are identical, so ground clearance is not a version filter.
Short ranking from the numbers only
- Fastest 0–100: 2106 1.6 MT and 21061 1.5 MT (16 s), not the 1.3 (18 s).
- Highest top speed: 2106 1.6 MT (155).
- Lowest combined fuel: 21063 1.3 MT (8.6).
- Lowest highway fuel: 2106 1.6 MT and 21061 1.5 MT (7.4), not the 1.3 (7.8).
- Lightest: 21061 1.5 MT (1035 kg).
- Best kg/hp: 2106 1.6 MT (14.1).
- Best hp/L: 21061 1.5 MT (49.6).
If you want one line: 2106 1.6 MT for torque and top speed, 21061 1.5 MT when 16 s and 7.4 highway are enough without the last 2 hp, 21063 1.3 MT when 8.6 combined outweighs 18 s and 145 km/h.
