Most bang for the buck – Cabin noise, WLTP

Perfect—here’s the same table with an extra EUR column added (using ECB ref. rate 1 EUR = 11.003 SEK, rounded to the nearest €100).

* Index = WLTP_km × (70 − dB) ÷ price (SEK); ranks don’t change by currency.

Why these winners (unchanged):

  • EV6: one of the lowest noise figures post-facelift + competitive price → best “quiet km per krona”. (adac.de)
  • Enyaq 85x: very quiet at 130 km/h; Sportline AWD costs more than base 85 but still scores well. (adac.de)
  • Ioniq 6: strong WLTP and calm cabin, often under 600k. (adac.de)
  • ID.7 Pro: relaxed motorway manners (Tourer GTX even quieter at 64.5 dB), SWE Edition pricing helps. (volkswagen.de)
  • Polestar 2: huge WLTP on paper but a bit noisier at 130 → value index dips. (adac.de)
  • Model Y LR: solid WLTP, but ADAC dB and current SWE pricing hurt the “quiet-for-the-bucks” score. (ADAC PDF)

Notes & caveats

  • Noise depends on tires/wheels (20–21″ = more roar). Match the test wheels to your spec.
  • WLTP is manufacturer-stated; ADAC dB is a consistent 130 km/h test.
