VEHICLES_FW.MODEL_YEAR_FW AS MODEL_YR
FROM

WHERE
VEHICLES_FW.ARCHIVE_STATUS_FW - 'N'
AND ( (MODEL_YEAR_FW) >2003)

    You could use the modulo operator %

    SELECT VEHICLE_FW.MODEL_YEAR_FW % 3 AS interval3y, 
       count(*) AS COUNT_VEHICLES,
       min(VEHICLES_FW.MODEL_YEAR_FW) AS MODEL_YR
FROM FWUSER.VEHICLES_FW
WHERE VEHICLES_FW.ARCHIVE_STATUS_FW = 'N'
  AND MODEL_YEAR_FW >= 2003
GROUP BY interval3y
ORDER BY interval3y

    You may use DENSE_RANK() analytic function as the following:

    WITH RANKS AS
(
  SELECT MODEL_YEAR_FW, ARCHIVE_STATUS_FW,
         CEILING(DENSE_RANK() OVER (ORDER BY MODEL_YEAR_FW)/3) GRP
  FROM VEHICLES_FW
  WHERE ARCHIVE_STATUS_FW = 'N'AND MODEL_YEAR_FW >2003
)
SELECT CONCAT(MIN(MODEL_YEAR_FW), '-', MAX(MODEL_YEAR_FW)) AS MODEL_YR,
       COUNT(MODEL_YEAR_FW) AS COUNT_VEHICLES
FROM RANKS
GROUP BY GRP
ORDER BY GRP
