Metin Mueller is the ev.guru team’s editorial pseudonym for charging technology, vehicle specifications and transparent cost calculations.
Editorial approach
Define the basis, then show the math: precise language, explicit units and a conclusion with visible limits.
- Identify the trim, model year and US-market configuration before comparing figures; keep EPA and WLTP ratings, and usable and gross capacity, separate.
- Show the math and its assumptions, separating energy use, charging losses, subscription fees and time-based charges.
- Cite technical claims where they appear. Mark missing figures as unknown and distinguish manufacturer specifications from editorial calculations.
