Some key numbers related to Volkswagen's admission that it programmed diesel cars to cheat on emissions tests:

— 475,000: Number of cars with 2-liter diesel engines in the U.S. that Volkswagen has agreed to buy back or repair under a $15 billion settlement released last month. The settlement may get preliminary approval from a federal judge on Tuesday, with final approval likely this fall.

— 80,000: Number of Volkswagens with 3-liter diesel engines in the U.S. They aren't covered by this settlement.

— 2009-2016: Model years affected by the diesel scandal.

— $12,500 to $44,000: Range of values for the affected Volkswagen diesels before the scandal became public on Sept. 18, 2015. Owners who sell their cars back to VW would get the clean trade-in value as determined by the National Automobile Dealers Association depending on the model, age, mileage and options on their car.

— $5,100 to $10,000: Amount of additional compensation owners would get, whether they opt for a buyback or have Volkswagen fix their cars.
