Question 2

Which is cheaper to insure — Kia EV9 or Rivian R1S?

Accepted Answer

Insurance varies by state, ZIP code, age, and credit tier. Enter a ZIP to see a localized estimate; both vehicles' national-average premiums are shown on the compare page.

Question 3

Which depreciates faster — Kia EV9 or Rivian R1S?

Accepted Answer

Depreciation over the first five years is itemized in the cost breakdown. Luxury and EV models typically lose more value in early years; segment leaders and Toyota/Honda hold value better.

Question 4

Is the Kia EV9 better than the Rivian R1S?

Accepted Answer

It depends on how you drive. The compare page scores both vehicles across five pillars — cost of ownership, powertrain, driver assistance, livability, and safety — combined into one MotiveGrid Score, alongside a 5-year cost breakdown and a clear verdict. Pick the one whose strengths match how you actually use a car.

Question 5

Why do these two vehicles get different ADAS (driver-assist) scores?

Accepted Answer

Our ADAS scale weighs sensor stack (radar + camera vs camera-only), hands-free operating domain (highway vs any divided road), driver-monitoring quality (eye-tracking vs torque sensor), and whether the system gets OTA improvements. Two vehicles can advertise the same feature names and still score 20+ points apart once operating envelope and update cadence are accounted for.

Question 6

Why does EV depreciation differ from a comparable gas vehicle?

Accepted Answer

EV residuals follow a different curve for three reasons. Aggressive manufacturer price cuts and subsidized lease deals compress the used market — a new EV often transacts well below MSRP, dragging down used values. Battery state-of-health uncertainty creates a risk premium on used EVs. And fast-improving charging speed, range, and ADAS hardware make a 3-year-old EV feel older than a 3-year-old gas car.
