We regularly provide a look at how individual 3 and 4 year-old sleepers are performing, but it’s been a while since we’ve looked at 5 year-old models.

As of January, we now consider the 2011 model year to be 5 years old. With this in mind, 2011’s came in almost identically to where 2010’s came in one year ago, at $65,841 vs. $66,440, respectively. This result is interesting in that 2011 was the first full model year to feature “2010” (SCR) emissions. There were a small number of 2011’s built with pre-2010 emissions, but for all intents and purposes, we consider 2011 the first full SCR year. 

SCR engines are generally considered to achieve better fuel economy than 2007-2010 engines. Reliability may be somewhat improved as well, but anecdotal evidence suggests that improved component longevity due to lower underhood temperatures may be counteracted by an increased number of sensor issues. In addition, some used truck buyers are wary of new technology, particularly when it requires them to buy additional fluids. These factors contribute to the similar performance of the two emissions regimens. 

Getting to the numbers, the Volvo 730/780 turned in the best performance of this cohort, leading the market average by 12.5% in the most recent 12 months. The Peterbilt 386 started out 2014 extremely strongly, but depreciated more heavily than other models starting mid-year. Still, that model outperformed the market average by 7.0% in this period. Other models performed similarly to each other, except for the International ProStar, which underperformed the market average by 11.5%. For reference, 94.8% of 2010 ProStars reported sold in 2014 were equipped with the Cummins ISX. See graph below for detail.

Stay tuned for data on 3 and 4 year-old models in the March edition of Guidelines, available shortly.
