The Toyota iQ 1.0-litre stands out as a remarkable feat of automotive engineering, packing surprising practicality into an ultra-compact footprint under three metres long. Launched to challenge conventional city cars, it combines efficient power, innovative interior layout, and strong safety credentials, making it a smart choice for urban dwellers and budget-conscious drivers alike.
Engineering Marvel in Miniature
At its core, the Toyota iQ reimagines what a tiny car can achieve. Measuring just 2.98 metres in length yet as wide as a typical family hatchback like the VW Golf, it employs a ‘super stance’ design with wheels pushed to the extremities for enhanced stability. This square-like profile not only aids parking but also contributes to a planted feel on the road.
The 1.0-litre three-cylinder petrol engine delivers 67 bhp, prioritizing efficiency over outright speed. Paired with a five-speed manual gearbox (or optional automatic), it suits stop-start city traffic while offering reasonable composure on faster roads. Tall gearing helps suppress noise at motorway speeds, with reviewers noting a characterful engine note that revs eagerly without overwhelming refinement.
Power and Performance Breakdown
Expect modest acceleration: 0-60 mph takes around 14 seconds, but the light 880 kg kerb weight makes it feel livelier than figures suggest, especially in urban settings. Real-world testing reveals urban economy at 57.7 mpg, extra-urban at 72.4 mpg, and combined at 65.7 mpg, with CO2 emissions of 99 g/km qualifying for VED Band A (zero tax in its era).
| Performance Metric | Value |
|---|---|
| Power | 67 bhp |
| 0-60 mph | ~14 seconds |
| Top Speed | 90 mph |
| Fuel Economy (Combined) | 65.7 mpg |
| CO2 Emissions | 99 g/km |
| Turning Circle | 4.1 metres |
This efficiency translates to a theoretical 450-mile range, though everyday driving might yield slightly less due to the slender 32-litre fuel tank’s quick depletion. Owners report 48 mpg in mixed city-highway use, praising its frugality for commutes.
Interior Space: Smart Solutions for Four
Inside, the iQ defies its size with clever packaging. The dashboard shifts forward on the passenger side, allowing that seat to slide ahead and free legroom for a rear passenger—enough for an adult on short trips. Shoulder room rivals larger hatches, while a miniaturized climate unit tucked into the dash preserves footwell space.
- Asymmetric dash design maximizes front legroom.
- Passenger seat adjusts further forward for rear access.
- Thin 12 cm-high fuel tank under the floor enables a flat load area.
- Velcro ‘handbag’ glovebox on passenger side adds quirky utility.
Despite the ingenuity, the boot is minimal—barely four inches deep—suitable for groceries but not family luggage. Rear space works for two small passengers or one adult, positioning the iQ as a 3+1 seater rather than a true four-seater.
Driving Dynamics: Urban Ace with Highway Poise
Behind the wheel, the iQ surprises with composed handling. Firm suspension delivers a sorted ride, absorbing bumps without harshness, while the tight 4.1-metre turning circle excels in tight streets. It’s no hot hatch, but responsive steering and low weight make it enjoyable on twisty roads.
On motorways, tall gearing and good noise insulation maintain cruising ease, outperforming expectations for a city car. The manual shifter includes a shift light for optimal economy, and the optional auto suits pure urbanists. Overall, it blends Mini-like cheekiness with Smart-like rationality, earning praise for personality in a bland segment.
Safety Features That Punch Above Weight
Safety is a highlight, with nine airbags including a pioneering rear curtain airbag for side impacts. Euro NCAP awarded it five stars, bolstered by its low centre of gravity and rigid structure. While the rear airbag may offer limited protection in severe crashes, the comprehensive suite—front, side, knee, and curtain—sets it apart in the mini car class.
Reliability and Ownership Experience
Toyota’s reputation shines through: the iQ is ‘bomb-proof’ used buy, with few major issues beyond occasional exhaust replacements on older models. Low running costs, cheap insurance (group 6-8), and minimal servicing make it appealing. Fuel costs stay low at around 60+ mpg potential, ideal for high-mileage users.
Owners appreciate its durability, with examples from 2009 still roadworthy in 2022. However, parts availability for the niche model requires checking specialists, and resale holds steady without bargains.
