Toyota Sienna Generations and Specs: Full Model Overview (1997–present)

A guide to all Toyota Sienna generations from 1997 to the present: minivan specs, power ranges from 187 to 296 hp, notable versions, and which Sienna to buy.

The Toyota Sienna is a minivan produced from 1997 to the present, with outputs ranging from 187 to 296 hp across its lineup. It suits families who need a spacious people-carrier with an automatic gearbox and a choice of front-wheel drive or 4x4, from affordable V6 versions to the current hybrid. Every Toyota Sienna generation, without exception, has been sold exclusively with an automatic transmission — there has never been a manual option in this data — and the body type has always been a minivan. This overview covers all Toyota Sienna generations and their key specs: production years, power ranges, engine displacements, drivetrain options, and the number of modifications in each period.

Toyota Sienna generations

1 generation (1997–2003)

The first Toyota Sienna was built from 1997 to 2003 as a minivan with 197–213 hp, an automatic transmission, and front-wheel drive only, in 2 modifications. This is the only generation in the model's history without a 4x4 option: all first-generation cars are FWD. The mass-market version was the Sienna 3.0 AT (213 hp) with a 2995 cc engine, accelerating to 100 km/h in 9.4 seconds. The power spread within the generation was narrow — just 16 hp separated the base 197 hp version from the top 213 hp one.

2 generation (2003–2006)

The second-generation Toyota Sienna (2003–2006) came as a minivan with a single output of 233 hp, an automatic gearbox, and — for the first time — a choice of FWD or 4x4 across 2 modifications. The mass version was the Sienna 3.3 AT (233 hp) with a 3311 cc engine and 4x4, which reached 100 km/h in 8.7 seconds. That 8.7-second sprint made it quicker than the first-generation 3.0 AT by 0.7 seconds, despite the added weight of all-wheel drive. With only one power level, the choice within this generation came down purely to drivetrain.

2 generation, restyling (2006–2009)

The restyled second generation, sold from 2006 to 2009, broadened the range to 215–269 hp and 6 modifications with FWD or 4x4 — three times as many versions as the pre-restyling car. The Sienna 3.3 AT (233 hp) with its 3311 cc engine and 4x4 remained the mass version, keeping the 8.7-second sprint to 100 km/h. The new top of the range was the Sienna 3.5 AT (269 hp) with a 3456 cc engine and 4x4, accelerating in 9.0 seconds. This restyling introduced the 3456 cc engine that would go on to power every third-generation Sienna for the following fifteen years.

3 generation (2010–2014)

The third-generation Toyota Sienna (2010–2014) offered the widest power spread of the model's history: 187–296 hp across 5 modifications, all with automatic transmissions and FWD or 4x4. The 187 hp base version is also the lowest output ever offered in a Sienna. The Sienna 3.5 AT (268 hp) FWD with a 3456 cc engine was the mass version, consuming 11.8 l/100km. The 296 hp flagship, also on the 3456 cc engine, came in two forms: a 4x4 version at 11.7 l/100km and a more frugal FWD version at 10.8 l/100km — a full liter per 100 km between the two drivetrains at the same power.

3 generation, restyling 1 (2014–2017)

The first restyling of the third generation ran from 2014 to 2017 with 266–296 hp and 4 modifications; the sub-200 hp base versions were dropped, raising the floor of the range by nearly 80 hp. The Sienna 3.5 AT (296 hp) with the 3456 cc engine became the mass version in FWD form at 10.8 l/100km, and was also offered with 4x4 at 11.7 l/100km. All modifications kept the automatic gearbox and the choice of front- or all-wheel drive.

3 generation, restyling 2 (2017–2021)

The second restyling (2017–2021) kept the 266–296 hp range but trimmed the lineup to 3 modifications. The Sienna 3.5 AT (296 hp) again came as FWD (10.8 l/100km) and 4x4 (11.7 l/100km) versions, joined by the newer Sienna 3.5 AT (266 hp) FWD at 11.8 l/100km. All three shared the same 3456 cc engine, so the differences came down to tuning and drivetrain rather than displacement. This was the final period for the V6 Sienna: the generation that followed abandoned the 3.5-liter engine entirely.

4 generation (2020–present)

The fourth-generation Toyota Sienna, in production since 2020, switched entirely to a 2487 cc hybrid powertrain with 245 hp, an automatic transmission, and FWD or 4x4 in 2 modifications. There is no non-hybrid version: the displacement dropped by almost a liter compared to the outgoing 3456 cc V6, and output settled between the old range's extremes. The Sienna 2.5 AT (245 hp) consumes 6.5 l/100km with FWD and 6.7 l/100km with 4x4 — the lowest figures in the model's history, and roughly 4 liters per 100 km less than the most economical V6 version. The gap between FWD and 4x4 consumption also shrank to just 0.2 l/100km, against a full 0.9–1.0 l/100km in the third generation.

Which Toyota Sienna to buy

On the used market, the long third generation (2010–2021 including both restylings) offers the largest choice: 12 modifications across three sub-periods sharing the same 3456 cc engine family, which simplifies parts sourcing. Fourth-generation cars (2020–present) are the newest option but exist in only 2 hybrid modifications, both at 245 hp, so the choice there is simply FWD or 4x4.

Which Toyota Sienna to avoid

Within the 3 generation, restyling 2 (2017–2021), the Toyota Sienna 3.5 AT (266 hp) FWD is dominated by the Sienna 3.5 AT (296 hp) FWD from the same years: the 296 hp version delivers 30 hp more while consuming less fuel — 10.8 l/100km against 11.8 l/100km. With both versions sold side by side from 2017 to 2021 on the same 3456 cc engine, the numbers favor the 296 hp car on every measured axis.
