Daihatsu Copen Grade Guide: Robe vs Cero vs GR SPORT — All Differences Explained

Japan's only new kei sports car with a power-folding roof, decoded grade by grade — and now, with a production end date on the calendar. Here's exactly what separates Robe, Cero, and GR SPORT, plus what the shutdown announcement actually means if you're buying new, buying used, or importing.

📅 Current Model: Second-generation Copen (LA400K, since June 2014) 🚗 Grades: Robe · Robe "S" · Cero · Cero "S" · GR SPORT 🇯🇵 Japan Domestic Market — 660cc Kei Sports Car ⚠️ Production Ending Late August 2026

Important: Daihatsu Is Ending Copen Production in August 2026

On September 29, 2025, Daihatsu officially announced that the current Copen (LA400K) will end production in late August 2026, with sales continuing at dealers only until existing stock runs out. Daihatsu has stated it is "continuing various studies" toward eventually bringing the Copen nameplate back, but has made no commitment on a launch date, and reporting since suggests any next-generation Copen — potentially previewed by the FR-layout "K-OPEN" concept shown at the Japan Mobility Show 2025 and Tokyo Auto Salon 2026 — realistically wouldn't arrive before 2027–2028 at the earliest.

Practically, this means new-car ordering has already tightened through 2026, with some grades, body colors, and options unavailable at certain dealers as production slots fill. If you're chasing a specific new-build spec, that window is closing; if you're shopping used or planning to import, expect used prices to firm up over time as the current-model Copen becomes a fixed, non-renewable supply.

What Is the Daihatsu Copen?

The Copen is a two-seat, front-engine, front-wheel-drive kei-class roadster — and, notably, the only MT-equipped passenger car currently sold in Daihatsu's lineup. It first appeared in June 2002 as Japan's first kei car with a power-folding hardtop ("Active Top"), a genuinely novel feature at that price and size at the time, and ran through 2012 as the first-generation L880K.

The current second-generation LA400K arrived in June 2014, built around a lightweight, high-rigidity "D-Frame" chassis and originally sold with a swappable exterior-panel concept called "Dress-Formation." Over its production run it has spawned several distinct looks under one platform — Robe, Cero, Exprey (discontinued), and GR SPORT, added in October 2019 with retuned suspension and handling. Unusually for a Daihatsu-Toyota badge-sharing arrangement, the GR SPORT variant is supplied to Toyota keeping the "Copen" name rather than being rebadged — one of the very few cases where a Toyota-sold Daihatsu keeps its original nameplate.

Grade Lineup at a Glance

Prices and fuel economy figures per Daihatsu's official Japan-market pricing page. Hokkaido-region pricing runs slightly higher across all grades due to cold-weather specification. Every grade shares the same fuel economy — the differences here are entirely about styling, chassis tuning, and interior trim, not the engine.

One Engine Across the Whole Range

Every Copen grade — Robe through GR SPORT — uses the same 658cc three-cylinder DOHC turbocharged KF-VET engine, producing approximately 64 PS and 92 Nm (9.4 kgm), the same maximum output permitted under Japan's kei-car industry agreement. Buyers choose between a 5-speed manual or a 7-speed "Super Active Shift" CVT with paddle-shift capability on S and GR SPORT grades — there's no separate turbo/non-turbo split like some other Daihatsu kei models, since the Copen has been turbocharged across the board since this generation launched.

Full Grade Breakdown

Robe — Base Grade

From ¥1,983,300 (CVT)

• Active Top electric power-folding roof
• 16-inch aluminum wheels (Robe/Cero design)
• Tilt steering
• Electronic card key
• Automatic air conditioning (push-button)

Robe is the sharp-edged, contemporary-styled base grade — everything you need for open-top kei sports car driving without stepping up to sport suspension or upgraded seating.

Robe "S" — Sport-Tuned Robe

From ¥2,196,700 (CVT)

• Same core equipment as Robe (Active Top, 16-inch alloys, tilt steering, auto air conditioning)
• Adds push-button start (versus Robe's electronic card key without push start)
• Recaro-style sport seats (suede-look), offered in beige, black, or red
• Bilstein shock absorbers
• MOMO leather-wrapped steering wheel (paddle shift included on CVT cars)

The "S" suffix consistently means the same three-part upgrade across the Copen range: sport seats, Bilstein dampers, and a MOMO steering wheel — Robe "S" is where that package first appears.

Cero — Retro-Styled Base Grade

From ¥2,040,500 (CVT)

• Active Top electric power-folding roof
• 16-inch aluminum wheels (Robe/Cero design)
• Push-button start
• Tilt steering
• Electronic card key
• Automatic air conditioning (push-button)

Cero wears round, retro-inspired headlamps that echo the first-generation Copen's look — cosmetically distinct from Robe's sharper face, but mechanically identical underneath. Note that Cero includes push-button start as standard, something Robe reserves for its "S" variant.

Cero "S" — Sport-Tuned Cero

From ¥2,255,000 (CVT)

• Same core equipment as Cero (Active Top, 16-inch alloys, push-button start, tilt steering, auto air conditioning)
• Recaro-style sport seats (suede-look), beige/black/red
• Bilstein shock absorbers
• MOMO leather-wrapped steering wheel with paddle shift (CVT)

Functionally the retro-styled equivalent of Robe "S" — same suspension and interior upgrade, different face.

GR SPORT — Top Grade

From ¥2,501,400 (CVT)

• Active Top electric power-folding roof
• Push-button start
• Tilt steering
• Electronic card key with GR logo
• Automatic air conditioning (push-button)
• GR SPORT-exclusive BBS forged 16-inch aluminum wheels
• GR SPORT-exclusive Recaro sport seats (suede-look, black, with embroidered GR logo)
• GR SPORT-exclusive MOMO leather-wrapped steering wheel with paddle shift (CVT)
• GR SPORT-exclusive self-illuminating 3-gauge meter cluster (red needles, red illumination)
• Piano-black center cluster trim
• Piano-black door grips

GR SPORT is the only grade with its own dedicated wheel design and instrument cluster rather than sharing parts with Robe or Cero, plus the firmer, more track-focused suspension tuning introduced when the grade launched in 2019.

Robe vs Cero vs GR SPORT — Which Design Language Fits You?

• Robe suits buyers who want a modern, sharp-edged sports-car face and don't need the "S" or GR SPORT's firmer damping.
• Cero suits buyers drawn to the round-headlamp retro look that nods to the original 2002 Copen — mechanically identical to Robe aside from included push-button start.
• GR SPORT suits buyers who want the firmest, most track-oriented setup Daihatsu offers on this platform, plus the only grade-exclusive wheel design, gauge cluster, and interior trim in the range.

Which Grade Should You Buy?

💴 Best for Lowest Cost

Choose the Robe. Full Active Top functionality, 16-inch alloys, and automatic climate control for the lowest entry price in the range.

⭐ Best for Classic Styling

Choose the Cero. The retro round-headlamp face and standard push-button start make it a small step up from Robe for a modest price difference.

🏆 Best for a Sportier Feel Without the Premium

Choose the Robe "S" or Cero "S". Bilstein dampers, Recaro-style sport seats, and a MOMO leather steering wheel meaningfully change the driving experience versus the base grades, at a lower price than GR SPORT.

🚀 Best Overall Specification

Choose the GR SPORT. It's the only grade with its own wheel design, gauge cluster, and interior trim, plus the firmest suspension tuning Daihatsu offers on the Copen — the enthusiast's pick, and reportedly a strong choice for the model's final production run given how competitively it's priced against rivals like the Mazda Roadster or Toyota GR86.

Importing a Daihatsu Copen

For buyers sourcing a Copen from Japanese auction, a few identification points matter:

• Headlamp shape is the fastest way to separate Robe/Robe "S"/GR SPORT (sharp, contemporary lamps) from Cero/Cero "S" (round, retro lamps).
• Interior seat material and steering wheel confirm an "S" or GR SPORT grade at a glance: Recaro-style suede-look sport seats and a MOMO leather steering wheel mean you're looking at an "S" grade or GR SPORT, not a base Robe or Cero.
• BBS forged wheels and a red-needle 3-gauge cluster are GR SPORT-exclusive — no other grade carries either.
• Transmission matters for value and rarity: the Copen is one of very few current Japanese passenger cars still offered with a manual gearbox, and 5MT examples — especially in GR SPORT spec — are likely to hold particular interest as the model's production run closes out.
• Given the announced production end, confirm build date and remaining factory warranty carefully on any near-new unit, and expect increasing scarcity on desirable configurations (GR SPORT 5MT in particular) as dealer stock is exhausted through and after 2026.

Always confirm the exact grade, transmission, and accident history against the chassis number before bidding, since equipment details — especially the "S"-package upgrades — are easy to misread from auction photos alone. If you're bidding from overseas, running the chassis number through a Japanese auction sheet and history check before you commit is the safest way to confirm the car in front of you actually matches the grade it's listed under — that's exactly the kind of check we built JPChecker to make simple.

Frequently Asked Questions

Is the Daihatsu Copen being discontinued? Yes. Daihatsu announced on September 29, 2025 that the current Copen (LA400K) will end production in late August 2026, with sales continuing only until existing dealer stock is sold. Daihatsu has said it is studying a future Copen but has not confirmed a launch date or specification for any successor.

Will there be a new Copen after 2026? Daihatsu has stated it intends to bring the Copen nameplate back but has made no formal commitment. A concept called "K-OPEN," shown at the Japan Mobility Show 2025 and Tokyo Auto Salon 2026, previews a possible rear-wheel-drive kei-class direction, but reporting suggests any production version realistically wouldn't arrive before 2027–2028 at the earliest.

What is the cheapest Daihatsu Copen grade? The Robe grade is the entry point, starting from ¥1,983,300 (tax included) with the 7-speed CVT.

What is the difference between Copen Robe and Copen Cero? They share the same mechanicals, wheels, and core equipment. Cero uses round, retro-styled headlamps and includes push-button start as standard, while Robe uses sharper, more contemporary headlamp styling and reserves push-button start for its "S" grade.

What does the "S" mean on a Copen grade? "S" grades (Robe "S," Cero "S") add Bilstein shock absorbers, Recaro-style suede-look sport seats, and a MOMO leather-wrapped steering wheel with paddle shift on CVT models, over the equivalent base grade.

Does every Copen have a turbo engine? Yes. All Copen grades — Robe through GR SPORT — use the same 658cc turbocharged three-cylinder KF-VET engine producing around 64 PS, the maximum output allowed under Japan's kei-car industry agreement.

Can you still get a manual transmission Copen? Yes, as of the current production run. A 5-speed manual is available across every Copen grade, making it one of the very few passenger cars still sold new in Japan with that option — a detail worth confirming carefully given the announced production end.
