Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Sprinter 3500.
The 2021 Mercedes‑Sprinter 3500 is the latest iteration of the brand’s full‑size van platform, retaining the robust power‑train architecture that has defined the series while accommodating a 13.2‑quart oil capacity and accepting a range of modern viscosities—0W‑20, 0W‑30 or 0W‑40—to suit varying service conditions. Within the broader 2007‑2022 complaint record, the model line saw its fewest reported issues in 2008 (just one) and its peak in 2016 (61 complaints), placing the 2021 unit toward the more reliable end of the spectrum as the trend has generally moved downward since that high‑complaint year. Consequently, researchers can view the 2021 Sprinter 3500 as a comparatively stable point in the model’s reliability trajectory, reflecting incremental refinements rather than any radical redesign.
