About $2,496 a year for full coverage on a national average — 74% more than the $1,438 average car. Insurers rate the BMW M340i at an index of 174 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2022-2024).
The premium isn't spread evenly across the BMW M340i: Collision — damage to your own car in a crash — carries its highest loss index at 238, while Property damage sits at 118. Those 120 points are the real reason behind the price, and they are the part a quote form never shows you. Among 78 luxury cars we hold data for, the M340i ranks #50 from cheapest, above the class median of 138. Against what the car is worth the bill looks different again: a 2021 M340i sells for a median $39,995, so a year of cover costs 6.2% of the car's value. Over 5 generations of data the index has climbed from 120 (2018-2020) to 174 (2022-2024). Calculated from 5 insurance-loss records and live US listing prices.
Why a M340i costs what it does
Insurers don't price a car with one number — they track losses separately for each kind of cover. An index of 100 is the average vehicle, so anything above means this model generates costlier claims of that type:
Read it as «where the money goes». A high Collision figure means these cars are expensive to repair after a crash; a high Comprehensive figure points at theft, weather and vandalism instead. Estimated annual split at $2,496: Liability (BI + PD) $1,198 · Collision $699 · Comprehensive $300 · Other (UM / PIP) $300.
