Citroen revives the 2CV for an electric age

📝 Discussion Summary (Click to expand)

Three prevalent themes in the discussion

  1. Heritage/retro design as a selling point (and its limits)
  2. Many commenters praised Citroen’s nostalgic 2CV revival for feeling “like cars from the future” while echoing classic cues.
  3. forestingfisher: “I'm really digging Citroen's design recently. Along with Renault and Hyundai, they feel like cars from the future instead of the bloated aggressive and angular design we've come to expect.”
  4. Others warned that nostalgia alone won’t sustain sales: skywal_l suggested the pattern “first as a tool then as a totem,” and spankibalt noted, “Heritage and vintage looks, will only take you so far.”

  5. Demand for simple, affordable EVs without excess “cruft”

  6. A strong desire emerged for basic electric vehicles that avoid mandatory touchscreens, flashy infotainment, and unnecessary driver‑assist gadgets.
  7. detritus: “the European car industry's ripe for disruption by a nimble car company that can make really basic EVs with none of the pointless, excessive cruft that seems endemic in every new car release.”
  8. jubilee33 praised a rented Fiat sedan whose “controls were heaven compared to most of the new offerings,” and hn_submit said, “I'd love an EV with no screen except for the instrument dash and buttons, dials and sliders to operate the A/C and radio.”

  9. Price pressure from Chinese EVs and the need for cheap, reliable cars

  10. Repeatedly, users argued that European EVs are overpriced and that Chinese models (e.g., BYD Seagull, Dacia Spring) set the benchmark for affordability.
  11. hn_submit: “What people want most of all is a cheap and reliable car.”
  12. hn_submit also highlighted the BYD Seagull: “The BYD Seagull is a real car for $10,000 which is quite large to boot.”
  13. PorciiVorbesc summed up the competitive reality: “As they face mounting competition from Chinese manufacturers, Citroen and other European brands are exploiting their heritage as a means of selling modern motors.”

Minimalist EV Dashboard OS

Summary

  • An open-source operating system for electric vehicle instrument clusters that replaces complex touchscreen infotainment with a lightweight UI driven by physical buttons, dials, and a small display for speed, range, battery state, and legally required backup‑camera video.
  • Core value proposition: gives drivers a distraction‑free, tactile interface while meeting safety regulations, appealing to EV owners and builders who crave simplicity.

Details

Key Value
Target Audience DIY EV converters, small EV manufacturers, fleet operators seeking low‑cost, reliable UIs
Core Feature Plug‑and‑play dashboard software with CAN‑bus integration, physical button mapping, and optional backup‑camera overlay
Tech Stack Linux (Yocto/Buildroot), Qt/QML or HTML/CSS/JS via Electron, SocketCAN, Rust for safety‑critical modules
Difficulty Medium
Monetization Revenue-ready: hardware kits + optional support subscriptions ($199 kit, $15/yr support)

Notes

  • HN commenters repeatedly asked for “an EV with no screen except for the instrument dash and buttons, dials and sliders to operate the A/C and radio” (hn_submit) and praised Slate Auto’s ethos; this OS directly satisfies that desire.
  • Provides a practical utility for the growing aftermarket EV conversion scene and could spark discussion on open‑source vehicle software standards.

SimpleEV Marketplace

Summary

  • A curated web marketplace that lists only affordable, basic EVs (under €20 k) in Europe, emphasizing models with minimal infotainment, physical controls, and real‑world range; includes a “simplicity score” based on user‑reported UI clutter.
  • Core value proposition: saves budget‑conscious buyers time by surfacing the truly spartan EVs they want, avoiding the premium‑feature overload that dominates current listings.

Details

Key Value
Target Audience Price‑sensitive European consumers, urban commuters, first‑time EV buyers seeking no‑frills transport
Core Feature Searchable database with filters for price, range, physical button ratio, and user‑rated simplicity
Tech Stack React frontend, Node.js/Express backend, PostgreSQL, hosted on Vercel/AWS
Difficulty Low
Monetization Revenue-ready: affiliate fees per lead ($25) + optional premium listings for dealers ($49/mo)

Notes

  • Users lamented that “people want most of all a cheap and reliable car” (hn_submit) and praised the Citroën Ami, Dacia Spring, and Renault 5 for being simple; this site aggregates those models and highlights their simplicity.
  • Could become a go‑to reference for journalists and policy makers discussing the affordable EV segment, driving community engagement.

Physical Infotainment Replacement Kit (PIRK)

Summary

  • An aftermarket hardware‑software kit that replaces the factory touchscreen in popular EVs (e.g., VW ID series, Renault Zoe, Nissan Leaf) with a compact panel of physical buttons, rotary dials, and a small LCD for essential vehicle data, while retaining the legally mandated backup‑camera feed.
  • Core value proposition: lets drivers downgrade distracting screens to tactile controls without sacrificing safety or OEM integrations.

Details

Key Value
Target Audience EV owners frustrated with complex touchscreens, fleet managers seeking driver‑focused interfaces
Core Feature CAN‑bus bridge, button/dial hardware, LCD display, backup‑camera video passthrough, and configuration app
Tech Stack ESP32 microcontroller, CAN transceiver, 2.4" TFT LCD, Linux‑based companion app (Flutter) for settings
Difficulty High
Monetization Revenue-ready: one‑time kit sale ($149) with optional OEM‑specific adapters (+$30)

Notes

  • Commenters noted “backup camera by law” (testing22321) and desired “no screen except for the instrument dash and buttons, dials and sliders” (hn_submit); PIRK satisfies both.
  • Offers a tangible solution that could spark discussion on right‑to‑repair and user‑choice in vehicle UX, appealing to the privacy‑ and simplicity‑conscious HN crowd.
