IRVINE, Calif., and SANTA MONICA, Calif. -

Incentives were on the way up last month, as average transaction prices were reported to have fallen slightly from April.

According to TrueCar.com data, the average incentive spending for light vehicles in May was $2,677, up $17 (0.7 percent) from May 2013 and up $91 (3.5 percent) from April.

TrueCar estimated the ratio of incentive to average transaction price for light vehicles was 8.7 percent in May 2014, up 1.1 percent from May 2013 and up 7.5 percent from April 2014. 

Perhaps a result of ramped up incentives, both TrueCar and Kelley Blue Book reported a slight decline in transaction prices from April.

KBB reported the estimated average transaction price for light vehicles in the United States was $32,307 in May, which is up $635 from May 2013 and down $79 from April.  

“Small and midsize car share has declined slightly, as car shoppers opt for small and midsize crossovers, helping boost this month’s average transaction price,” said Karl Brauer, senior analyst for Kelley Blue Book.  “Benefitting from strength among the crossover segment, the Acura MDX now comprises more than a third of Acura’s sales, boosting the brand’s transaction prices 5.5 percent year-over-year and helping keep Honda’s overall ATP flat.”

According to TrueCar data,  the average transaction price was $30,646 in May 2014, down $149 from May 2013 and down $1,174 from April.

“Industry-wide, we saw average transaction prices contract slightly in May,” said Larry Dominique, president of ALG and executive vice president of TrueCar.  “Conversely, Chrysler and GM were able to command higher prices, while shrinking their incentive spend-to-price ratio. This is a positive brand indicator for the two automakers.”

Highlighting transaction prices for individual brands, KBB analysts pointed out Volkswagen performed particularly well in May.

“Revealing a healthy average transaction price increase this month is Volkswagen Group, up 5.5 percent from last year,” said Alec Gutierrez, senior analyst for KBB.  “However, this is due to a decrease in the share of Volkswagen brand sales and a corresponding increase in Audi share.  Following the re-introduction of the entry-level A3 sedan, Audi’s average transaction price is down 2.5 percent year-over-year, while the Volkswagen brand is relatively flat.”

For domestic brands, Chrysler Group reported the biggest gain in average transaction price, reporting a 4.8 percent bump up from May 2013.
