Meta description: Daihatsu Copen GR SPORT LA400K — compact 658cc JDM roadster: verified specs, market prices, and buying tips for international used-car buyers.

Introduction

The Daihatsu Copen GR SPORT (LA400K) is a compact Japanese kei-class roadster aimed at buyers who want an engaging, small convertible with sporty styling. The GR SPORT trim brings sport-focused design cues and chassis tuning from Daihatsu’s Gazoo Racing collaboration. This guide covers verified specifications, practical ownership notes, and import-ready buying tips for international buyers interested in this JDM model code LA400K.

Daihatsu Copen GR SPORT LA400K Overview

The Copen is Daihatsu’s two-seat kei convertible, and the GR SPORT variant emphasizes a sportier look and sharper handling compared to standard trims. The supplied dataset indicates the LA400K model code and shows production activity between 2021 and 2026, with the GR SPORT released in December 2024. This version retains the Copen’s compact footprint and lightweight design while adopting GR-specific styling and chassis elements. The LA400K is primarily offered in the Japanese domestic market (JDM) and is popular with buyers seeking an imported small roadster that’s easy to park and economical to run in urban environments.

Daihatsu Copen GR SPORT (LA400K) Specifications

Note: Only verified values from the supplied dataset are shown. Several common specifications (power output, torque, transmission, fuel economy, and tyre sizes) were not provided and are therefore omitted.

Engine and Performance

Verified information shows the LA400K GR SPORT is fitted with a 658 cc engine consistent with Japanese kei-car regulations. Exact engine configuration, power and torque figures, and transmission options were not supplied in the dataset, so those specifics cannot be confirmed here.

What can be said factually: the GR SPORT nameplate suggests suspension and chassis tuning meant to sharpen handling and improve body control versus non-GR Copen trims. The vehicle’s light curb weight (870 kg) and short dimensions typically yield a nimble and responsive driving feel in town and on twisty roads. The model’s FF layout favors predictable front-end grip and efficient packaging for two occupants.

Exterior Design and Dimensions

The Copen’s compact footprint—3,395 mm long, 1,475 mm wide and 1,280 mm tall—makes it one of the smallest modern roadsters, ideal for tight Japanese streets and easy urban parking. GR SPORT variants usually include sportier bumpers, unique grille and badging, and distinct alloy-wheel designs; however, specific GR SPORT exterior details for the LA400K were not provided in the supplied data.

Practical highlights of the Copen platform include a low-slung roadster stance and a folding roof mechanism (standard across the Copen lineup historically), which combine open-top driving fun with the convenience of weather protection when needed. The short overall length and light weight support lively handling but limit cargo capacity—buyers should expect modest luggage room suitable for day trips rather than long road-tripping with lots of gear.

Interior, Comfort and Technology

The Copen is a two-seater focused on driver engagement and simple ergonomics. The supplied dataset confirms seating for two but does not list infotainment, upholstery, or specific convenience features for the GR SPORT trim. Historically, Copen interiors balance sportiness with city-focused practicality—compact cabins, driver-oriented controls, and the essentials in infotainment and safety tech, varying by trim level.

Buyers importing a JDM Copen GR SPORT should verify fitted equipment in the listing or auction sheet, such as air conditioning, power windows, navigation or smartphone integration, and any GR-specific interior trim or badging.

Fuel Economy and Everyday Practicality

No official JC08 or WLTC fuel economy figures were provided in the supplied data. The 658 cc kei-class engine typically offers strong fuel efficiency in similar models, suited to urban and light suburban use. Because verified fuel-consumption data are unavailable here, buyers should request official fuel economy figures from the seller or confirm them through the vehicle’s documentation before purchase.

Practicality notes: with two seats and compact luggage capacity, the Copen is best suited as a weekend car, city runabout, or for buyers prioritizing style and open-top driving over family hauling capability.
