The Daihatsu Sirion stands out as a quirky yet practical compact hatchback that punches above its weight in space and fun factor. Designed for city dwellers and budget buyers, this model delivers surprising roominess, decent economy, and agile handling despite its modest power outputs.
Origins and Model Lineup
Introduced in the mid-2000s, the Sirion targeted the supermini segment with a focus on maximizing interior volume within a sub-four-meter footprint. Available primarily with 1.0-liter and 1.3-liter petrol engines, it catered to those prioritizing affordability over outright performance. The lineup included base S trims and higher SE variants, both emphasizing value through standard equipment like air conditioning and multiple airbags.
Buyers appreciated its Japanese engineering, which promised reliability in a market dominated by European rivals. Though Daihatsu’s UK presence waned, used examples remain available at bargain prices, often under £1,000 for well-maintained units.
Engine Options and Performance Breakdown
The entry-level **1.0-liter three-cylinder** engine produces 68bhp, accelerating from 0-60mph in 13.6 seconds with a top speed of 99mph. Reviewers note its unhurried pace suits urban commutes, where the deeper, charismatic engine note adds character despite some noise at higher speeds.
Stepping up to the **1.3-liter unit** at around 86-100bhp (depending on market), performance improves noticeably, with quicker acceleration and better motorway capability. Owners report it feels surprisingly rapid in daily use, redlining eagerly while maintaining composure.
| Engine | Power | 0-60mph | Top Speed | Fuel Economy (mpg) |
|---|---|---|---|---|
| 1.0L 3-cyl | 68bhp | 13.6s | 99mph | 45-52 |
| 1.3L | 86-100bhp | ~10s | 109mph | 43-50 |
Transmissions include a five-speed manual standard, with some markets offering a four-speed automatic that shifts smoothly with well-spaced ratios.
Interior Space and Practicality
Despite its compact 3.6-meter length, the Sirion excels in packaging. Six-foot passengers fit comfortably front and rear, with ample headroom and legroom surprising for the class. The cabin design prioritizes utility: a 60/40 split-folding rear bench expands boot space from 250 to over 500 liters, ideal for shopping or weekend getaways.
- Standard features on base models: Four airbags, air con, electric windows, remote locking.
- SE upgrades: Alloy wheels, rear parking sensors, height-adjustable steering.
- Interior materials are functional but not premium; hard plastics hold up well over time.
Equipment levels rival pricier competitors, making it a smart pick for families on a budget.
Driving Dynamics and Road Manners
Handling shines with direct power steering and strong grip, even through corners with some body roll. It’s nimble around town, tackling speed bumps and urban obstacles with ease. Motorway trips are viable, with one reviewer logging 500 miles comfortably.
Ride quality is firm, prioritizing fun over plushness, but it remains composed. Noise insulation is adequate for the era, though wind and engine sounds intrude at speed.
Fuel Efficiency and Running Costs
Economy is a highlight: the 1.0-liter achieves 45-52mpg, while the 1.3 manages 43-50mpg in mixed driving. Low insurance groups and emissions keep ownership cheap. Used prices start low, with minimal maintenance needs—oil top-ups common but parts affordable.
Owners praise its dependability; one noted just wiper blades and oil after 1,500 miles on a £370 purchase.
Pros and Cons at a Glance
- Pros: Spacious interior, low costs, fun handling, high equipment.
- Cons: Modest power (1.0L), firm ride, some engine noise, dated materials.

Owner Experiences
Long-term tests reveal its charm: “Eats up miles merrily,” with real-world economy beating official figures despite minor leaks. Rally variants and modified examples highlight tunability.
International reviews echo this: Australian owners laud equipment and economy; lowered daily drivers handle superbly.
