These are the explainers behind the numbers on this site. If a figure on a car page raised a question — why there are two range figures, what a 10-80% time really measures, whether cold weather is as bad as people say — the answer is here, with the sources.
The data-driven pieces — what charging costs per month, whether a 48-amp home charger is worth it, how many kWh a full charge really takes — are on the blog, newest first.

Every car we hold data for, sliced the way people usually narrow a shortlist. These are generated from the database, so they stay right as cars are added.
- All electric cars in the database — every model, with range, charging and efficiency
- By body: SUVs · saloons · pickups
- By drive: rear-wheel drive · all-wheel drive
- By battery: all chemistries explained, or jump to LFP, NMC and NCA cars
