Rating
9/10
The Toyota Sienta is the answer to a specific Sri Lankan question: “We need to fit grandparents on weekend trips, but we don’t want to pay Voxy money or feed a 1800cc engine.” The 2026 Sienta solves that problem with the latest 1.5L THS-II hybrid — same drivetrain family as the Yaris Cross — packaged into a 7-seat sliding-door body.
This review covers the 2026 Sienta Hybrid Z — the volume trim in active SL imports.
What you get
- 1.5L M15A-FXE three-cylinder + electric motor (latest THS-II, 116 hp combined)
- eCVT transmission
- 5 doors (sliding rear sliders both sides), 5 or 7 seats (configurable)
- 4,260mm length, 1,695mm width — fits standard parking spaces
- Toyota Safety Sense standard
- 10.5-inch infotainment on Z grade, panoramic view monitor
- Third row that folds completely flat into floor (5+2 configuration)
How it drives
The Sienta’s chassis is shared with the Yaris Cross — TNGA-B platform — but the body is taller and longer for 7-seat packaging. Expect:
- Economy — 28+ km/L mixed driving, class-leading for any 7-seater on sale
- Steering — light and direct; easy to manoeuvre in tight Colombo lanes despite the 7-seat body
- Ride — softer than Yaris Cross; tuned for family comfort, not driver feel
- Power — 116 hp combined is enough for 5 occupants; with 7 onboard plus luggage on a hill, you’ll feel it
The third row is the honest compromise: it folds flat into the floor when not in use, so you have a real 5-seat hatchback most of the time and a 7-seat option when grandparents visit. Adults sitting in the third row for more than an hour will not be comfortable. This is the same trade-off as every compact 7-seater on sale globally — the Sienta is no exception.
The standout is fuel economy. 28+ km/L from a 7-seat family vehicle is genuinely class-leading. A Toyota Voxy Hybrid does 18–20 km/L. An Alphard Hybrid does 14–16. The Sienta’s economy is 40–60% better than its larger siblings.
Sri Lanka tax math (2026 Sienta Hybrid Z, JPY 3.9M FOB)
| Line | Amount (LKR) |
|---|---|
| FOB (JPY → LKR) | 7,800,000 |
| CIF | 8,100,000 |
| CID (20%) | 1,620,000 |
| Customs surcharge (50% of duty) | 810,000 |
| Excise (1,500cc × LKR 1,500/cc) | 2,250,000 |
| Luxury tax (CIF below threshold) | 0 |
| VAT base | ~12,780,000 |
| VAT (18%) | 2,300,000 |
| Clearing + transport + dealer | ~1,400,000 |
| Indicative landed selling price | LKR 18–22M |
For the full breakdown, see landed price explained.
60% LTV cap reality: an LKR 20M landed Sienta requires LKR 8M cash up front — substantial, but the cheapest 7-seat family hybrid in the SL import shortlist by a wide margin.
Auction-sheet notes
- Target grade: 4.5 or higher. 2026 production is essentially new — grade 4.5 examples are abundant; grade 5 carries minimal premium.
- Watch for: nothing model-specific. Inspect for stone chips on front bumper and any rear-bumper scuffing (sliding-door cars often pick up door-edge contact in Japanese parking).
- Hybrid battery: latest THS-II generation. Same architecture as Aqua, Yaris Cross, Corolla Cross — proven 300k+ km longevity on original battery.
- 5-seat vs 7-seat trim: both available; the 7-seat costs roughly LKR 200–300k more landed. Specify clearly when sourcing.
- Z grade gives you: panoramic monitor, leather steering, 10.5-inch infotainment, LED headlights, automatic sliding doors.
Who should buy this
| Pick the Sienta 2026 if… | Pick the Voxy Hybrid 2025 if… |
|---|---|
| You need 7 seats occasionally, not daily | You need 7 seats daily — three-row family use |
| Fuel economy is a priority | Cabin space and long-trip comfort matter |
| You want the lowest-tax-band 7-seater | You’re spending LKR 25M+ regardless |
| You’ll often use it as a 5-seater | You want premium-feel interior |
Verdict
9/10. The Sienta 2026 is the correct answer for the Sri Lankan family that needs occasional 7-seat capability and would otherwise default to a Voxy or Noah. The 1500cc tax band keeps it accessible, the sliding doors make daily family use practical, and 28+ km/L is unmatched in the 7-seat class.

The bZ4X is Toyota's first ground-up electric SUV — a midsize, ~71 kWh BEV co-developed with Subaru, built on the e-TNGA platform.
