Daihatsu Copen CERO S LA400K Overview

The Copen with model code LA400K is the modern kei-class roadster from Daihatsu sold in Japan. The CERO S is a factory trim/variant positioned as a well-equipped option within the Copen range. Based on supplied production data, this LA400K generation has model years in the sample range 2021–2026 and includes factory updates released around December 2024 for this trim. The LA400K follows the kei-car regulations for compact dimensions and a sub‑660cc engine capacity.

Daihatsu Copen CERO S LA400K Specifications

Notes: Values in this table reflect only the verified data provided. Several common specification items (power, torque, transmission details, fuel economy, and safety equipment) were not available in the supplied dataset and are shown as unavailable.

Engine and Performance

Verified specification shows the LA400K Copen CERO S uses a 658 cc engine — consistent with Japan’s kei-car regulations. The provided data confirms the drivetrain layout is FF (front-wheel drive) and the vehicle kerb weight is 870 kg.

Specific output figures (horsepower and torque) and the fitted transmission type were not available in the supplied specifications. Because those figures are model- and year-dependent, buyers should request the exact engine power, torque and gearbox information from the seller or the vehicle listing before purchase.

Driving impressions for lightweight kei roadsters typically include nimble handling due to short length and low weight, and responsive urban performance from small-displacement turbocharged or naturally aspirated engines where fitted. However, these are general observations and not a substitute for confirmed LA400K performance specs.

Exterior Design and Dimensions

The LA400K’s quoted exterior dimensions are compact: 3,395 mm long, 1,475 mm wide and 1,280 mm tall. These measurements place the Copen firmly in the kei-car class — easy to park and manoeuvre in tight Japanese streets.

With a kerb weight of 870 kg, the Copen CERO S should feel light and agile. The compact footprint and low height typically contribute to a low centre of gravity and enhance cornering stability at moderate speeds. Specific trim design touches and wheel size details for the CERO S were not provided and should be confirmed on the listing or with the seller.

Interior, Comfort and Technology

The supplied specification set did not include interior dimensions, seating capacity, infotainment or safety feature lists for the CERO S. Buyers should verify specifics such as seating layout, material quality, infotainment connectivity (Apple CarPlay/Android Auto), air conditioning, and any advanced driver assistance features directly from the vehicle listing or dealer.

When evaluating a Copen for import, check for service history, interior condition, and whether any optional packages were fitted at the factory or by previous owners.

Fuel Economy and Everyday Practicality

Official fuel-economy figures (JC08 or WLTC) and fuel type were not available in the supplied data. Given the 658 cc engine displacement, the LA400K is likely designed with efficiency in mind, but buyers must request the verified JC08 or WLTC figures for the exact model year and transmission combination.

For everyday use, the Copen’s compact size makes it ideal for city driving, short commutes and weekend leisure use. Confirm fuel type requirements (regular petrol vs. premium) and fuel tank capacity with the seller before import.

Is the Daihatsu Copen CERO S LA400K a Good Used Car to Buy?

Strengths (based on verified data and class characteristics)

• Compact dimensions and light weight (3,395 × 1,475 × 1,280 mm; 870 kg) are ideal for city driving and easy parking.
• Market sample prices show an accessible average (approx. ¥1.6M JPY) compared with original MSRP (¥2,255,000).
• Distinctive styling and niche appeal can make the Copen a desirable lifestyle import.

Limitations and considerations

• Several important specs (power, torque, transmission, fuel economy, safety equipment) are not in the supplied dataset — verify before buying.
• Market trend in the supplied sample is falling (-7.3%) and sample size is small (9 listings), so pricing and availability can change quickly.
• As with any imported used car, confirm maintenance history, accident history, and corrosion condition.

Inspection checklist before import

• Verify exact engine output and transmission type.
• Check full service records and verify mileage.
• Confirm vehicle history and auction grade if applicable.
• Inspect convertible roof operation and seals (crucial on roadsters).
• Check body for corrosion or repair work and ensure VIN/chassis code matches export paperwork.

Frequently Asked Questions

Final Verdict

The Daihatsu Copen CERO S LA400K offers compact dimensions and a lightweight design attractive to buyers seeking a niche kei-class roadster. The supplied data shows reasonable used-market pricing versus original MSRP, but several technical details are missing from the provided specification set. International buyers should verify engine outputs, transmission, safety equipment, and fuel-economy figures before committing. If you value easy urban maneuverability, distinctive styling and the kei-car ownership experience, the Copen CERO S LA400K is worth considering—provided you complete a careful inspection and document check.
