About $4,191 a year for full coverage on a national average — 191% more than the $1,438 average car. Insurers rate the BMW 640i at an index of 291 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2017-2019).
The premium isn't spread evenly. Comprehensive — theft, weather, vandalism, animals — carries this car's highest loss index at 343, while Collision sits at 239. That gap is the real reason behind the price, and it's the part a quote form never shows you. Against what the car is worth the bill looks different again: a 2015 640i sells for a median $18,700, so a year of cover costs 22.4% of the car's value. Over 8 generations of data the index has climbed from 256 (2010-2012) to 291 (2017-2019). Calculated from 8 insurance-loss records and live US listing prices.
Why a 640i 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 $4,191: Liability (BI + PD) $2,012 · Collision $1,173 · Comprehensive $503 · Other (UM / PIP) $503.
How it changed by generation
Insurance-loss index of the 640i across every generation in the data. Newer isn't automatically cheaper — driver-assist systems cut crash frequency, while sensors and aluminium panels push repair bills up:
Each point averages every recorded variant of that generation. The 640i has become more expensive to insure over time (+35 points).
What a 640i costs by state
Where you park matters as much as what you drive. The 640i's index applied to each state's average premium — the same car, the same cover, different postcode:
| State | 640i est. / yr | vs national |
|---|---|---|
| Florida | +39% vs US | |
| Louisiana | +38% vs US | |
| New York | +32% vs US | |
| District of Columbia | +26% vs US | |
| Georgia | +21% vs US | |
| Texas | +20% vs US | |
| Wisconsin | -30% vs US | |
| Hawaii | -31% vs US | |
| Idaho | -32% vs US | |
| North Dakota | -33% vs US | |
| Vermont | -33% vs US | |
| Maine | -36% vs US |

Insurance-loss indices published for real vehicles, combined with NAIC state average premiums. It's claim history, not a quote engine — so it shows what these cars actually cost insurers rather than what one company would offer you.
Will my own quote match this?
Treat it as a baseline for the car itself. Your figure also moves with age, driving record, deductible, mileage and ZIP code — the same 640i can differ by hundreds between two drivers.
