Introduction

The Daihatsu Copen LA400K 20th Anniversary Edition is a limited celebratory take on Japan’s compact two-door kei convertible. Small, stylish and distinctly Japanese, this edition appeals to buyers who want a collectible kei roadster with factory provenance and a premium spec compared with standard Copen models. This guide uses verified Japanese-market data to outline what is known about the LA400K 20th Anniversary Edition and to help international buyers decide if it fits their needs.

Daihatsu Copen LA400K Overview

The Daihatsu Copen LA400K refers to the third-generation Copen family, produced in the 2010s and refreshed across model years. The 20th Anniversary Edition (released in September 2022) commemorates the Copen’s milestone with unique trim and limited production. In Japan the Copen is sold as a kei car—a compact, lightweight category governed by strict size and engine displacement limits—making it particularly appealing for city use and collectors of Japanese domestic market (JDM) vehicles.

Notes: The table contains only verified data supplied for the LA400K 20th Anniversary Edition. Horsepower, torque, fuel economy figures, wheelbase, seating capacity, fuel tank capacity, factory wheel and tyre sizes, and some safety/convenience features were not provided in the verified data and are therefore omitted.

Engine and Performance

Verified data shows the LA400K 20th Anniversary Edition is fitted with a 658 cc engine, consistent with kei-car regulations in Japan. The exact power (PS/hp) and torque figures for this specific 20th Anniversary trim were not provided in the verified dataset and are therefore not stated here.

Drivetrain layout for the verified specification is FF (front-engine, front-wheel-drive). Transmission details were not available in the supplied data. Because many Copen LA400K models use small turbocharged or naturally aspirated three-cylinder engines in conjunction with automatic or CVT gearboxes, buyers should verify the transmission and tuning for any specific used example before purchase.

What is factual: the LA400K is lightweight (870 kg factory weight), which together with a small-displacement engine typically produces a lively, nimble feel in urban and twisty-road driving. What is not verified here: exact acceleration, top speed, and engine output for the 20th Anniversary Edition.

Exterior Design and Dimensions

The verified exterior dimensions are compact: 3,395 mm long, 1,475 mm wide and 1,280 mm tall. These proportions are textbook kei car, making the Copen LA400K exceptionally easy to park and manoeuvre in tight Japanese city streets and congested urban areas abroad.

The 20th Anniversary Edition is a special trim, so expect unique exterior touches compared with standard Copen models—badging, limited paint or trim accents, and possible exclusive wheel designs. Those visual upgrades are often the reason buyers choose limited editions. Confirm any edition-specific exterior features with photos and the vehicle’s option list when reviewing listings.

Interior, Comfort and Technology

Detailed interior specifications and technology options for the 20th Anniversary Edition were not included in the verified data. Generally, Copen cabins are two-seat layouts focused on driver engagement rather than rear-seat space or extensive cargo capacity.

When evaluating a specific LA400K 20th Anniversary car, check:

  • Condition and operation of the convertible roof/operation (if equipped with a retractable roof).
  • Presence and condition of factory anniversary trim, upholstery and badges.
  • Functionality of infotainment, HVAC and driver aids.
  • Service history and evidence of regular maintenance.

Fuel Economy and Everyday Practicality

Official Japanese-market fuel economy figures (JC08 or WLTC) were not supplied for this specific 20th Anniversary Edition; therefore no official consumption numbers are stated here. As a kei car with a sub-660 cc engine and low curb weight, the LA400K is typically designed for efficient urban driving and short trips, but exact figures will vary by engine tuning, transmission and optional equipment.

Practicality-wise, the Copen is best suited to single drivers or couples who prioritise style, weekend drives and city ease over cargo capacity or family use. Its compact size is an asset for import buyers who want a unique, easily stowed car in tight garages.
