The best small cars – driven, rated and ranked

How we tested small cars

When reviewing small cars, we evaluate them against a range of practical, technical, and user-focused criteria to see how they perform in real-world conditions. Here’s what we look for:

1. Efficiency

Efficiency is important in any car. But especially to small ones. When reviewing cars we compare real-world efficiency measurements to WLTP ones made up of laboratory tests. All the cars on this list are broadly efficient.

2. Interior comfort and space

We measure legroom, headroom, and storage space. Cabin noise levels at motorway speeds and ride comfort on various road surfaces are also assessed.

3. Performance

We evaluate acceleration, braking, and cornering across city, suburban, and motorway routes. Overall speed is not important to this test, but acceleration is, due to real-world scenarios such as getting up to speed for a motorway.

4. Technology

Infotainment systems are tested for ease of use, responsiveness, and smartphone integration (Apple CarPlay/Android Auto). We evaluate ADAS features (adaptive cruise, lane-keeping, automated parking) to check if they have been modified to suit the UK’s roads.

5. Build quality

We inspect fit and finish, panel alignment, and interior materials. We look and listen for any rattles, squeaks, or cheap-feeling components that might annoy.

6. Practicality

We assess ease of entry/exit, visibility, turning circle, and parking aids. We also test features such as powered tailgates, storage compartments, and child seat installation points (ISOFIX).

7. Ownership costs

We review running costs including charging expenses (home and public), insurance, and maintenance schedules.
