Renault Symbioz

Renault Symbioz: which version to buy — 1.6 E-Tech vs 1.8 E-Tech

Between the two Renault Symbioz versions in the catalogue, the arithmetic is simple: 1.8 E-Tech is the higher-output buy (160 hp / 117 kW, 270 Nm, 1789 cm³, top speed measured at 180), and 1.6 E-Tech is the lower-output buy (145 hp / 106 kW, 205 Nm, 1600 cm³, top speed not measured). Both are Hybrid, Automatic with 1 speed, FWD, SUV 5-doors, on sale from 2024-07-01 in the same 1 generation.

Both are Hybrid, Automatic with 1 speed, FWD, SUV 5-doors, on sale from 2024-07-01 in the same 1 generation. There is no second generation to “wait for,” and no restyling to split the choice. The extra displacement (+189 cm³) buys +15 hp and +65 Nm; it does not buy a different gearbox, drive, or body.

Specs that actually differ between versions

Both versions use Hybrid, Direct injection (direct), 95, Automatic, 1, FWD. Cylinder count is not measured on either row. Boost is not measured on either row. Do not treat those blanks as “no cylinders” or “no boost”; they are not measured.

Engine: what the extra 189 cm³ buys

1.6 E-Tech displaces 1600 cm³ and is rated 145 hp (106 kW) and 205 Nm. 1.8 E-Tech displaces 1789 cm³ and is rated 160 hp (117 kW) and 270 Nm.

Displacement step: 1789 − 1600 = 189 cm³, which is 189 / 1600 ≈ 11.8% more swept volume.

Power step: 160 − 145 = 15 hp (15 / 145 ≈ 10.3% more). In kilowatts: 117 − 106 = 11 kW (11 / 106 ≈ 10.4% more). The hp and kW gaps line up; neither version is “hp-inflated” relative to the other on the given figures.

Torque step: 270 − 205 = 65 Nm (65 / 205 ≈ 31.7% more). Relative to the 11.8% extra displacement and the 10.3% extra power, torque is the large gap. If the decision is “which version to buy,” the 1.8 E-Tech case is a torque case, not a peak-power case.

Power per litre (hp ÷ litres from the given cm³):

• 1.6 E-Tech: 145 / 1.600 = 90.6 hp/L
• 1.8 E-Tech: 160 / 1.789 ≈ 89.4 hp/L

The smaller engine is slightly denser on peak power per litre (−1.2 hp/L on the larger unit). Buying 1.8 E-Tech is not buying a more highly stressed specific output; it is buying more cubic centimetres and, especially, more newton-metres.

Torque per litre:

• 1.6 E-Tech: 205 / 1.600 = 128.1 Nm/L
• 1.8 E-Tech: 270 / 1.789 ≈ 150.9 Nm/L

Here the larger engine is denser: +22.8 Nm/L. Per litre, 1.8 E-Tech is the stronger torque specification.

kW per litre:

• 1.6 E-Tech: 106 / 1.600 = 66.3 kW/L
• 1.8 E-Tech: 117 / 1.789 ≈ 65.4 kW/L

Same pattern as hp/L: the 1.6 E-Tech is marginally denser on peak electrical-equivalent power; the 1.8 E-Tech wins on absolute power and on torque density.

Nm per hp:

• 1.6 E-Tech: 205 / 145 ≈ 1.41 Nm/hp
• 1.8 E-Tech: 270 / 160 = 1.69 Nm/hp

Again the 1.8 E-Tech is the torque-heavy map on paper.

Both engines are Hybrid, Inline, Front, transverse, Direct injection (direct), 95. Neither version changes fuel, injection label, layout, or hybrid type. There is no petrol-only or diesel row in this model’s data to choose instead.

Gearbox and drive: no version split

1.6 E-Tech is Automatic, 1 speed, FWD. 1.8 E-Tech is Automatic, 1 speed, FWD. Buying the 160 hp row does not buy extra ratios or another driven axle. If the search is “Symbioz AWD” or a multi-speed Automatic, this catalogue does not list either.

The 1-speed Automatic is the same count on both versions. The choice is engine output, not transmission architecture.

Performance and mpg: what is measured, what is not

0–100: not measured on 1.6 E-Tech and not measured on 1.8 E-Tech. You cannot rank sprint from this dataset. The 15 hp / 65 Nm gap is real; a 0–100 gap is not measured.

Top speed:

• 1.6 E-Tech: not measured
• 1.8 E-Tech: 180

The only measured top speed in the model is 180 on 1.8 E-Tech. That is not a comparison of two measured figures; it is one measured figure and one blank. Do not invent a 1.6 E-Tech top speed by scaling 180 by 145/160.

Fuel consumption (city / highway / mixed): not measured on both versions. MPG and L/100 km cannot be used to pick a version here. Tank: not measured on both. CO2: not measured on both. Eco class: not measured on both.

If the buying question is “which Symbioz uses less fuel,” this source does not measure it. The Hybrid label is the same on 1.6 E-Tech and 1.8 E-Tech; it is not a differentiator.

Dimensions, weight, clearance: no version to pick on packaging

Kerb weight: not measured on 1.6 E-Tech and not measured on 1.8 E-Tech. Gross weight: not measured on both. Ground clearance: not measured on both. Wheel sizes: not measured on both. Tank: not measured on both.

Weight per horsepower therefore cannot be calculated. You cannot say the 145 hp car is “lighter per hp” or that the 160 hp car “carries more mass.” Those ratios need kerb mass, which is not measured.

Body is the same for both: SUV 5-doors, 1 generation, start 2024-07-01, stop not set (still the current generation in this data). There is no long-wheelbase, three-door, or second-generation body to choose.

Chassis labels that are present are identical, so they do not pick a version:

• Front suspension: Independent, spring (both)
• Rear suspension: Semi-independent, springorts hélicoïdaux, sem (both; English label as in the data)
• Front brakes: Ventilated disc (both)
• Rear brakes: Disc (both; English label as in the data)

Buying 1.8 E-Tech does not buy a different suspension type or a different brake type in this catalogue.

Generations: nothing to wait for, nothing to skip

Renault Symbioz has 1 generation in the data: 1 generation, from 2024-07-01, stop not set, SUV 5-doors, 2 versions. There is no generation 2 with more power, and no restyling row that changes hp, Nm, or body.

Comparison between generations is therefore empty: there is only one production window. The buyer is not choosing “early 1 generation vs later 1 generation” on these numbers; both 1.6 E-Tech and 1.8 E-Tech start 2024-07-01 and have stop not set.

What did not change because there is no second generation: Hybrid type, Automatic 1, FWD, SUV 5-doors, Independent, spring front, Semi-independent rear label, Ventilated disc / Disc. All of that is one-generation fact, not a facelift story.

Which version to choose

Choose 1.8 E-Tech if the numbers you care about are peak output and, above all, torque. It is +15 hp (+10.3%), +11 kW (+10.4%), +65 Nm (+31.7%) on +189 cm³ (+11.8%). Torque per litre is higher (≈150.9 vs 128.1 Nm/L). It is the only version with a measured top speed (180). Power per litre is not higher (≈89.4 vs 90.6 hp/L), so you are not paying for a more aggressive specific output; you are paying for a larger Hybrid and a much fatter Nm figure.

Choose 1.6 E-Tech if you want the same architecture at the lower rating: 145 hp, 106 kW, 205 Nm, 1600 cm³, still Hybrid, Automatic 1, FWD, 95, Inline, Front, transverse, Direct injection (direct), same SUV 5-doors, same suspension and brake labels. It is the higher hp/L of the two (90.6 vs 89.4). Top speed, 0–100, mpg, tank, CO2, kerb weight, gross weight, clearance, and wheels are not measured, so you are not choosing it because it is “slower on paper” in a sprint or “lighter” — those figures are not in the data.

Do not choose on gearbox, drive, body, generation, fuel, or chassis type. Those fields match. Do not choose on 0–100, mpg, weight, or clearance: not measured on both. Do not invent a third version; the model lists two names only: 1.6 E-Tech and 1.8 E-Tech.

What the extra output does not buy (arithmetic of identical fields): 0 extra speeds (1 vs 1), 0 extra driven ends (FWD vs FWD), 0 extra body doors (SUV 5-doors vs SUV 5-doors), 0 extra generations, 0 measured kg, 0 measured L/100 km. The only fully measured “upgrade packet” is 15 hp, 11 kW, 65 Nm, 189 cm³, and a 180 top-speed figure that exists only on 1.8 E-Tech.

If the buying rule is “take the version where more of the performance table is filled,” that is 1.8 E-Tech (top speed 180 vs not measured). If the buying rule is “take the smaller Hybrid with the higher specific power,” that is 1.6 E-Tech (90.6 hp/L). If the buying rule is “take the torque,” that is 1.8 E-Tech by 65 Nm and by 22.8 Nm/L.

Renault Symbioz 1 generation, two versions, one body: the choice is 145 hp / 205 Nm / 1600 cm³ (1.6 E-Tech) versus 160 hp / 270 Nm / 1789 cm³ / 180 top speed (1.8 E-Tech). Everything else that is labelled in the data is the same, and everything else that buyers usually compare is not measured.
