According to Black Book editors, trucks have started to see depreciation rates pick up steam over the last few weeks, highlighted so far by their largest weekly drop of 2015 this past week (0.41%). In looking at the 12-week segment moving averages, we can see how overall car and truck depreciation averages have reversed from the May-June time period in comparison to the July-August period.

“Truck segment depreciation levels continue to increase but remain lower than those of car segments. Last week’s drop in values was the highest weekly decrease seen year-to-date for trucks,” said Anil Goyal, Vice President of Automotive Valuation and Analytics.

• Overall, the volume-weighted car values decreased by 0.48% last week. This is similar to the average depreciation rate seen in the previous 12 weeks.
• Luxury Level Car and Prestige Luxury Car segments performed the best with values dropping less than 0.25% last week. Compact Car and Full-Size Car segments experienced the highest drop in values by over 0.70%.
• Overall, the volume-weighted truck values decreased by 0.41% last week. This is the highest level of weekly depreciation seen for trucks this year.
• Full-Size Crossovers dropped by 1.00% while Compact Crossovers dropped by 0.16% only, last week.
