Toyota Sienta

Toyota Sienta: which version to buy

If the choice is a Toyota Sienta in this catalogue, the practical split is simple: buy the lightest front-drive 1.5 CVT at 110 hp from 1 generation or its restylings when you want the lowest measured weight per horsepower (1220 kg / 110 hp = 11.1 kg/hp) and the only 0–100 km/h figure we have (12 s); buy the 2 generation 1.5 CVT Hybrid 74 hp when payload and a Hybrid label matter more than peak pow…

If the choice is a Toyota Sienta in this catalogue, the practical split is simple: buy the lightest front-drive 1.5 CVT at 110 hp from 1 generation or its restylings when you want the lowest measured weight per horsepower (1220 kg / 110 hp = 11.1 kg/hp) and the only 0–100 km/h figure we have (12 s); buy the 2 generation 1.5 CVT Hybrid 74 hp when payload and a Hybrid label matter more than peak power; buy an AWD 1.5 AT or 1.5 CVT when you need all-wheel drive and will accept 100 kg extra kerb weight versus the matching FWD 1.5 CVT. The model is a Compact Van listed across four catalogue entries from 2003-09-01 to 2018-08-31. There are two generations: 1 generation (2003-09-01–2006-04-30) with restyling 1 (2006-05-01–2011-01-31) and restyling 2 (2011-01-01–2015-06-30), then 2 generation (2015-07-01–2018-08-31). Every engine in the data is 1496 cm³, Inline, 4 cylinders, 4 valves per cylinder, Front, transverse, Distributed injection (multi-point), boost No. Fuel consumption (city, highway, mixed), CO2 and eco class are not measured on every version. Wheel sizes are not measured. Length is not measured. Prices are not in this dataset.

Generations: what actually changed on the numbers

Treat restylings as chapters of 1 generation, not as extra generations. The buyer question is what the later sheet buys versus the earlier one.

1 generation (2003-09-01–2006-04-30), Compact Van, 5 versions. This is the only window with both 1.5 AT and 1.5 CVT in FWD and AWD, and the only window with two fuels (92 and 95) on otherwise similar 110 hp cars. The light FWD 1.5 CVT 110 hp is 1220 kg kerb / 1600 kg gross, ground clearance 140 mm, 0–100 km/h 12 s, top speed 175 km/h. The AWD 1.5 AT cars at 105 hp and 110 hp are 1320 kg kerb; gross weight is not measured on those two 1.5 AT AWD lines. Two further 110 hp versions (1.5 CVT AWD and 1.5 AT FWD) run on 95, make 140 Nm instead of 141 Nm, and have kerb and gross weight not measured.

1 generation, restyling 1 (2006-05-01–2011-01-31), Compact Van, 2 versions. The line-up shrinks to an AWD 1.5 AT 105 hp (1320 / 1705 kg, 150 mm) and an FWD 1.5 CVT 110 hp (1220 / 1605 kg, 140 mm). Versus the 2003 FWD 1.5 CVT 110 hp, kerb is unchanged at 1220 kg, 0–100 km/h stays 12 s, gross rises by 5 kg (1605 vs 1600), and top speed is 180 km/h versus 175 km/h — a +5 km/h measured gain. Rear brakes remain Drum. Fuel is 92 on both remaining versions.

1 generation, restyling 2 (2011-01-01–2015-06-30), Compact Van, 3 versions. Same 105 hp AWD pair now appears as both 1.5 AT and 1.5 CVT (both 1320 / 1705 kg, 150 mm, 138 Nm at 4200 rpm). The FWD 1.5 CVT 110 hp is still 1220 / 1605 kg and 140 mm. 0–100 km/h and top speed on restyling 2 are not measured. Rear brakes still Drum. Fuel still 92.

2 generation (2015-07-01–2018-08-31), Compact Van, 3 versions, all named 1.5 CVT, all Variable, all 95 fuel, all rear brakes labelled Disc, all 145 mm clearance, all 42 L tank. The Hybrid 1.5 CVT 74 hp is FWD, 1380 / 1765 kg. The Gasoline 1.5 CVT 103 hp is AWD, 1380 / 1710 kg, and is the only Sienta here with rear suspension Independent, spring. The Gasoline 1.5 CVT 109 hp is FWD, 1320 / 1705 kg, compression 13.5, bore × stroke 72.5 × 90.6 (every other version in the whole catalogue uses 75 × 84.7). Versus 1 generation FWD 110 hp: 2 generation FWD 109 hp is 100 kg heavier at the same 1320 kg as the old AWD cars, −1 hp, −5 Nm (136 vs 141), +5 mm clearance (145 vs 140).

Engine and specs: every named version

Displacement is 1496 cm³ on all 13 lines (74 / 1.496 ≈ 49.5 hp per litre on the Hybrid; 109 / 1.496 ≈ 72.9 hp/L on 2 generation FWD; 110 / 1.496 ≈ 73.5 hp/L on 1 generation FWD). Peak power is always quoted at 6000 rpm except the Hybrid (4800 rpm). Layout is Inline, 4, Front, transverse, boost No, injection Distributed injection (multi-point) throughout.

Same name, different cars: three 2 generation 1.5 CVT lines (74 / 103 / 109 hp); two restyling-2 AWD cars both 105 hp but 1.5 AT versus 1.5 CVT; three 1 generation 1.5 AT lines (105 AWD, 110 AWD, 110 FWD) and three 1 generation 1.5 CVT lines (110 FWD 141 Nm, 110 AWD 140 Nm). Distinguish them by horsepower, drive and Newton-metres, not by renaming.

Engine oil capacity, oil type and engine number location are not measured.

Performance, mpg and what is not measured

0–100 km/h is measured on two cars only, both FWD 1.5 CVT 110 hp: 1 generation 12 s and restyling 1 12 s. Every other version: 0–100 km/h not measured. Top speed is measured on the same two: 175 km/h (1 generation) and 180 km/h (restyling 1). Restyling 2 and 2 generation: top speed not measured.

City, highway and mixed consumption are not measured on all 13 versions. mpg is therefore not a number you can use to pick a Sienta in this catalogue — including the Hybrid 1.5 CVT 74 hp. CO2 and eco class are not measured.

Torque spread is 111–141 Nm. The Hybrid 1.5 CVT 74 hp is 30 Nm below the strongest 1 generation FWD 1.5 CVT 110 hp (141 − 111 = 30). 2 generation Gasoline 1.5 CVT 109 hp at 136 Nm is 5 Nm below that 141 Nm peak. AWD 105 hp cars make 138 Nm at 4200 rpm — 200 rpm earlier than the 4400 rpm peaks on the 110 / 109 / 103 / 74 hp lines.

Weight, payload, ground clearance, tank, dimensions

Tank is 42 L on every version that lists it. Wheel sizes are not measured. Overall length is not measured.

Kerb and payload (gross − kerb) where both exist:

• 1 generation / restyling 1 / restyling 2 FWD 1.5 CVT 110 hp: 1220 kg kerb; restyling 1–2 gross 1605 kg → payload 385 kg; 1 generation gross 1600 kg → payload 380 kg. Ground clearance 140 mm. Lightest Sienta in the file. Weight per horsepower: 1220 / 110 = 11.1 kg/hp.
• Same generations AWD 1.5 AT 105 hp (and restyling 2 1.5 CVT 105 hp): 1320 kg, gross 1705 kg where measured → payload 385 kg. Clearance 150 mm (+10 mm vs the FWD 110 hp). Weight per horsepower: 1320 / 105 = 12.6 kg/hp. The AWD tax is +100 kg kerb for −5 hp versus the FWD 1.5 CVT 110 hp.
• 1 generation 1.5 AT 105 hp and 1.5 AT 110 hp AWD: 1320 kg kerb, gross not measured, 150 mm.
• 1 generation 1.5 CVT 110 hp AWD (140 Nm) and 1.5 AT 110 hp FWD (140 Nm): kerb not measured, gross not measured, 140 mm.
• 2 generation FWD 1.5 CVT 109 hp: 1320 / 1705 kg, payload 385 kg, 145 mm. 1320 / 109 = 12.1 kg/hp — 1.0 kg/hp worse than the 11.1 kg/hp FWD 110 hp cars, and the same 1320 kg kerb as the old AWD 105 hp cars.
• 2 generation AWD 1.5 CVT 103 hp: 1380 / 1710 kg, payload 330 kg, 145 mm. 1380 / 103 = 13.4 kg/hp. Heaviest kg/hp among Gasoline Sientas here. Payload is 55 kg less than the Hybrid with the same 1380 kg kerb (1765 − 1380 = 385 vs 1710 − 1380 = 330).
• 2 generation Hybrid 1.5 CVT 74 hp: 1380 / 1765 kg, payload 385 kg, 145 mm. 1380 / 74 = 18.6 kg/hp — 7.5 kg/hp worse than the light FWD 110 hp, 5.2 kg/hp worse than 2 generation FWD 109 hp. Highest gross in the file (1765 kg).

Front suspension is Independent, spring on all. Rear is Semi-independent, springorts hélicoïdaux, sem except 2 generation AWD 1.5 CVT 103 hp (Independent, spring). Front brakes Ventilated disc on all. Rear Drum on every 1 generation line including both restylings; rear Disc on every 2 generation line.

Which version to choose

Default family FWD, lowest mass per horsepower. Take 1 generation, restyling 1 or restyling 2 1.5 CVT 110 hp: 110 hp, 141 Nm, Variable, FWD, 1220 kg, 140 mm, 92 fuel. Restyling 1 is the only later car with both 12 s to 100 km/h and 180 km/h measured. Restyling 2 keeps the same 1220 / 1605 kg and 110 hp but 0–100 and top speed are not measured. 1 generation FWD 1.5 CVT 110 hp is the same 1220 kg and 12 s with 175 km/h and 1600 kg gross. Among these three, restyling 1 is the one with the higher measured top speed (+5 km/h).

Need Automatic, 4 instead of Variable. The Automatic, 4 gearbox exists only as 1.5 AT, and only in 1 generation (including restylings). After 2015-07-01 there is no Automatic in this catalogue — 2 generation is Variable only. For Automatic plus AWD: 1.5 AT 105 hp (1320 kg, 150 mm, 138 Nm) from 1 generation, restyling 1 or restyling 2; restyling 2 and restyling 1 list gross 1705 kg, the 2003 1.5 AT 105 hp does not. For Automatic plus the 110 hp peak: 1 generation 1.5 AT 110 hp AWD (141 Nm, 92, 1320 kg, gross not measured) or 1 generation 1.5 AT 110 hp FWD (140 Nm, 95, kerb not measured). There is no Automatic Hybrid.

Need AWD. Do not buy 2 generation expecting more power: the AWD 1.5 CVT 103 hp is 2 hp and 6 Nm below the old AWD 1.5 AT / 1.5 CVT 105 hp (138 Nm), 60 kg heavier (1380 vs 1320), and 5 mm lower (145 vs 150). What 2 generation AWD uniquely adds is Independent, spring at the rear and Disc rear brakes, plus 95 fuel. Payload on 2 generation AWD is 330 kg versus 385 kg on the 105 hp AWD cars that list gross 1705 kg. If AWD and 150 mm clearance matter more than rear-disc and independent rear, the restyling 2 pair — 1.5 AT 105 hp or 1.5 CVT 105 hp — match each other on 105 hp, 138 Nm, 1320 / 1705 kg and 150 mm; the only measured difference is Automatic, 4 versus Variable.

Hybrid. The only Hybrid is 2 generation 1.5 CVT 74 hp, FWD, Variable, 95, 1380 kg, 13.4 compression, power at 4800 rpm. It is 35 hp below the same-generation FWD 1.5 CVT 109 hp (109 − 74 = 35) and 60 kg heavier (1380 vs 1320). Payload matches that FWD 109 hp car at 385 kg because gross is 60 kg higher (1765 vs 1705). Consumption is not measured, so you cannot pick the Hybrid on mpg from this file. You pick it when the Hybrid type itself is the requirement.

2 generation FWD Gasoline if you want the newest Compact Van without Hybrid or AWD. 1.5 CVT 109 hp: 1320 kg, 136 Nm, 13.5 compression, 72.5 × 90.6, Disc rear, 145 mm, 95. Versus the 110 hp FWD 1.5 CVT you give up 100 kg lightness, 1 hp, 5 Nm and 10 mm of the old FWD’s 140 mm (you gain 5 mm versus that 140 mm actually — 145 − 140 = +5 mm). You also move from 92 to 95. 0–100 km/h and top speed are not measured. This is not the strongest or lightest Sienta; it is the lightest 2 generation car (60 kg under both 1380 kg siblings).

Fuel 92 versus 95. Every 1 generation 105 hp AWD and the 110 hp FWD 1.5 CVT (141 Nm) plus the 110 hp AWD 1.5 AT use 92. 2 generation and the two 140 Nm 1 generation 110 hp cars use 95. There is no consumption figure to offset the grade change.

What this catalogue cannot decide. Interior, 7-seat layout, USA / Taiwan / Singapore / Malaysia fitment, 2021–2026 model years, oil capacity and asking price are not in the data. Reliability and “is Toyota Sienta a good car” are not scored here; the measurable ranking is: lightest and strongest on paper = FWD 1.5 CVT 110 hp (1220 kg, 11.1 kg/hp); only Hybrid = 1.5 CVT 74 hp; only independent rear = AWD 1.5 CVT 103 hp; only Automatic after you leave Variable = 1.5 AT in 1 generation.
