Throughout most of 2014, trucks remained popular, but perhaps most notably, showed significantly stronger price retention than their smaller counterparts. And the story was no different during the last month of the year.

The midsize pickups trucks, in particular, saw prices hold the strongest this past month out of all vehicle segments, according to Kelly Blue Book’s December Blue Book Market Report.

Among the 20 vehicle segments KBB tracks, the mid-size pickups saw the best retained value, averaging retention of almost 78 percent.

“On average, truck segments tend to hold their value better than their SUV and car counterparts. As we continue to see a decline in fuel prices, we can expect an increase in demand and thus higher retentions to continue throughout the truck segments,” said Sean Foyil, analyst for Kelley Blue Book.

The midsize SUV/crossover segment came in second place for retention last month, with an average retention rate of 66.5 percent — considerably weaker than the midsize pickup truck segment.

The luxury and compact car segments retained 61 percent and 60 percent of their values on average, respectively, which ranks them Nos. 12 and 14 overall.

Making up the bottom of the list are subcompact, midsize and full-size car segments, which ranked Nos. 17, 18 and 19, overall.

The electric vehicles segment ranked the lowest at an average of 46 percent average retention.

This lineup is perhaps not surprising, given the current fuel price environment. The average price for regular conventional retail gasoline reached a low of $2.49 nationally in December, according to the report.

This marks a 67-cent year-over-year drop from 2013 and is pushing many consumers to consider trucks and SUVs, rather than more fuel-efficient choices. In turn, this demand is contributing to strength in truck prices and putting pressure on retention for the more fuel-efficient segments.
