Subaru Lucra

Subaru Lucra: which version to buy (2010–2014)

The Subaru Lucra was sold as 1 generation of Hatchback 5-door, from 2010-04-01 to 2014-09-30, in 5 catalogue versions. There is no later generation to “step up” to, so the buying question is only which of the five 0.7 petrol layouts to take.

The Subaru Lucra was sold as 1 generation of Hatchback 5-door, from 2010-04-01 to 2014-09-30, in 5 catalogue versions. There is no later generation to “step up” to, so the buying question is only which of the five 0.7 petrol layouts to take. All five share the same 658 cc Gasoline 3 Inline block, 10 compression, 56 × 66.8 bore and stroke, Distributed injection (multi-point), 95 fuel, 36 l tank, 880 kg kerb, 1100 kg gross, 160 mm ground clearance, Independent, spring front and Semi-independent, torsion rear, and Ventilated disc front brakes. What you actually choose is power (58 vs 64 hp), boost (No vs Turbo), gearbox (Variable vs Automatic), and drive (FWD vs AWD).

Generations: one window, five versions

1 generation (2010-04-01–2014-09-30), Hatchback 5-door, 5 versions. Production start and stop are identical on every line, so no restyling year splits the range. You are not choosing “new Lucra vs old Lucra”; you are choosing among five simultaneous specs.

The five names in the database, kept exactly, are:

• 0.7 CVT — 58 hp, No boost, FWD
• 0.7 CVT — 58 hp, No boost, AWD
• 0.7 AT — 58 hp, No boost, AWD, 4-speed Automatic
• 0.7 CVT — 64 hp, Turbo, FWD
• 0.7 CVT — 64 hp, Turbo, AWD

Four of the five are labelled 0.7 CVT. Distinguish them by horsepower (and, at the same horsepower, by FWD / AWD). Only 0.7 AT has a unique name.

Engines and specs

Displacement, cylinder count, layout, injection, compression, fuel grade, kerb weight and tank do not change with version. The extra equipment in the turbo pair is boost plus a different power/torque map, not a larger engine.

Performance and economy (mpg, 0–100)

0–100 km/h: not measured on all five versions. Top speed: not measured on all five. City / highway / combined consumption: not measured on all five. CO2 and eco class: not measured on all five.

You cannot rank these Lucras by published mpg or sprint times from this dataset. Ranking has to use the measured engine and mass figures.

Specific output on 658 cc:

• 0.7 CVT 58 hp and 0.7 AT: 58 / 0.658 ≈ 88.1 hp per litre (43 / 0.658 ≈ 65.3 kW/l).
• 0.7 CVT 64 hp turbo: 64 / 0.658 ≈ 97.3 hp per litre (47 / 0.658 ≈ 71.4 kW/l).

The turbo pair adds 6 hp (+10.3%) and 38 Nm (+58.5%). Peak torque moves from 4000 rpm to 2800 rpm (1200 rpm earlier). Peak power moves from 7200 rpm to 5700 rpm (1500 rpm earlier). Mass is unchanged at 880 kg, so mass per horsepower falls from 880 / 58 ≈ 15.17 kg/hp (naturally aspirated trio) to 880 / 64 ≈ 13.75 kg/hp (turbo pair) — about 1.42 kg/hp less to move per horsepower.

That is the entire measured performance difference: same kerb weight, more torque much lower in the rev range, slightly more peak power. Consumption is not measured, so a turbo does not get a fuel-economy claim here.

Dimensions, weight, tank, wheels

Kerb 880 kg, gross 1100 kg, payload 1100 − 880 = 220 kg — the same on 0.7 CVT 58 hp FWD, 0.7 CVT 58 hp AWD, 0.7 AT, 0.7 CVT 64 hp FWD and 0.7 CVT 64 hp AWD. Ground clearance 160 mm on all five. Tank 36 l on all five. Wheel sizes: not measured. Rear brakes: not measured. Engine position: not measured. Valves per cylinder: not measured.

AWD does not add listed kerb weight in this catalogue. FWD vs AWD is a drivetrain label, not a 880 vs heavier figure. Clearance does not rise with AWD. You are not buying extra millimetres of ride height or extra listed payload on any version.

Which version to choose

There is 1 generation, so generation-to-generation change is zero: years, body and the shared chassis numbers are the same. The choice is four binary (or near-binary) splits.

1. Naturally aspirated 58 hp vs turbo 64 hp

Buy 0.7 CVT (58 hp, FWD), 0.7 CVT (58 hp, AWD) or 0.7 AT if you want the No-boost map: 58 hp at 7200 rpm, 65 Nm at 4000 rpm. Buy 0.7 CVT (64 hp, FWD) or 0.7 CVT (64 hp, AWD) if you want Turbo: 64 hp at 5700 rpm, 103 Nm at 2800 rpm.

The turbo is the only step that changes the engine numbers. It is also the only step that changes specific output (≈88.1 vs ≈97.3 hp/l) and mass-to-power (≈15.17 vs ≈13.75 kg/hp). Torque is the large delta (+38 Nm, +58.5%); power is the small one (+6 hp, +10.3%). If “what the extra money buys” is interpreted as extra listed capability, the turbo pair is the only pair that buys extra listed capability. Gearbox and drive changes do not.

There is no turbo Automatic. If you want Turbo and Automatic together, that combination is not in the five versions.

2. FWD vs AWD (same engine)

At 58 hp Variable, 0.7 CVT FWD and 0.7 CVT AWD match on hp, kW, rpm, Nm, boost, tank, weights and clearance. At 64 hp Variable, 0.7 CVT FWD and 0.7 CVT AWD match the same way. AWD is therefore not a heavier or more powerful Lucra in this table; it is the same 880 kg car with AWD instead of FWD.

Pick FWD on 0.7 CVT 58 hp or 0.7 CVT 64 hp if you do not need AWD. Pick the matching AWD line if you do. 0.7 AT is AWD only — there is no FWD Automatic.

3. Variable vs Automatic

Only one of five is not a CVT: 0.7 AT, Automatic with 4 gears, 58 hp, No boost, AWD. Gear count on every Variable version: not measured (the field is empty, not a hidden number of ratios).

0.7 AT does not add power, torque, tank or payload versus 0.7 CVT 58 hp AWD. The arithmetic difference between those two is gearbox type only. If you want a 4-speed Automatic and accept 58 hp and AWD, 0.7 AT is the unique answer. If you want Variable, you still have four 0.7 CVT lines (two power levels × two drives).

4. Practical shortlist

• Lightest listed powertrain path, front drive, no turbo: 0.7 CVT (58 hp, FWD). Same 880 kg as the others; lowest peak power and torque.
• Same engine, four-wheel drive, still Variable: 0.7 CVT (58 hp, AWD).
• Same 58 hp engine, only Automatic, only AWD: 0.7 AT.
• Highest listed output, front drive: 0.7 CVT (64 hp, FWD) — 103 Nm, Turbo.
• Highest listed output plus AWD: 0.7 CVT (64 hp, AWD). Same 64 hp / 103 Nm as the FWD turbo.

If the priority is torque and earlier peak rpm, the turbo 0.7 CVT pair is the only measured upgrade. If the priority is a conventional Automatic, only 0.7 AT exists, and it stays at 58 hp. If the priority is AWD, three of five versions have it (0.7 CVT 58 hp AWD, 0.7 AT, 0.7 CVT 64 hp AWD). If the priority is fewest extra systems, 0.7 CVT 58 hp FWD is the baseline: No boost, FWD, Variable.

Prices are not in this dataset, so “extra money” here means extra listed specification (turbo map, AWD, or 4-speed Automatic), not a sticker delta. Reliability and known problems are not in this dataset; they are not ranked. Wheel size, 0–100, top speed and mpg are not measured — do not treat silence as “this Lucra has no consumption” or “this Lucra has no wheels”; the catalogue simply does not record those figures on these five versions.
