Toyota Aygo AB10

Weaknesses, engine ratings and buying advice

★★★★★
5.0 / 5.0 · Based on 1 engine variants · How we rate

The Aygo AB10 is Toyota's city car from the triple alliance with Peugeot 107 and Citroën C1 — built in Kolín, Czech Republic, powered by the Daihatsu three-cylinder 1KR-FE with 1.0 liter and 50 kW. A car with one ambition: getting from A to B reliably.

The 1KR-FE is frugal and long-lived if oil changes aren't neglected. The water pump is the only real weakness — it can leak from 40,000 miles. Chain-driven, consumption from 4.5 liters — the package works. The five-speed manual is robust; the semi-automatic MultiMode (automated manual) jerks chronically and should be avoided.

Rust becomes a concern after 10+ years: sills, rear wheel arches, and tailgate around the license plate. Front brakes wear quickly.

Test-drive checklist: Cold-start — rattling suggests chain tensioner. Test MultiMode in stop-and-go. Heater on max — heater core clogs easily.

2026 market: Between $1,700 and $5,500. Good examples under 60,000 miles are getting rare.

Insider pick: Aygo 1.0 with manual gearbox and A/C — the simplest city runabout.

Engine Overview

The Toyota Aygo AB10 is available with one engine variant at 65 hp.

1.0L · Petrol· 68–69 PS
2005 2014

Extremely robust one-litre three-cylinder with a maintenance-free timing chain. For a three-pot it runs surprisingly smoothly, but it has little low-end torque and wants to be revved. With regular oil changes every 10,000 to 15,000 km it is virtually indestructible. Past roughly 150,000 km oil consumption can creep up, so check the level when buying and watch for bluish smoke on a cold start. Ignition coils and the throttle body get dirty over time, causing a rough idle. For city and short-run use it is one of the most reliable options out there.

  • !! Water pump failure from 100,000 km

    The water pump on the 1KR-FE has a limited service life and can fail prematurely. Several cases of failure at relatively low mileages have been documented.

    Symptoms: Temperature gauge rising abnormally, coolant loss, squealing noise from the engine area

  • !! Water pump leaking from 60,000 km

    The water pump on the 1KR-FE tends to develop shaft seal leaks from around 50,000 km. The resulting coolant loss can lead to overheating if left unaddressed.

    Symptoms: Coolant level drops with no visible leak, coloured deposits around the water pump, elevated engine temperature

  • ! Elevated oil consumption due to piston rings from 150,000 km

    With predominantly short-trip use the piston rings tend to stick, leading to oil consumption of up to 1 litre per 3,000 km. Particularly common on older, high-mileage vehicles.

    Symptoms: Oil level drops noticeably between service intervals, blue smoke on cold start or under hard acceleration

Test Reports

AUTO BILD TÜV-Report

Below average

The braking system is the most serious weak point: brake disc wear, foot brake defects and corroded brake lines cause considerable costs. Lighting shows twice the average defect rate. Recalls affected rear axle welds and loose side windows.
