After a lackluster January-July period, in which only the MDX large CUV and RLX mid-large sedan were in the black, Acura is looking to get back on track in the year’s remaining five months.

MDX growth of 55.5% and RLX gains of 7.1% through July were in stark contrast to the brand’s other models, which all posted declines.

The midsize RDX CUV was flat through last month, down 1.0%. Acura’s car lineup, which includes the entry-level ILX and flagship RLX sedans, as well as the departing TSX and TL 4-doors, was running 34.4% behind January-July 2013’s volume.

But with the TSX/TL replacement, TLX, now arriving at U.S. dealers, Mike Accavitti, senior vice president and general manager for Acura, is expecting better days ahead.

“You know you can’t sell pavement in this business,” he tells WardsAuto in a recent phone interview, referring to the sell-down of the TSX and TL, and the later-than-expected arrival of the TLX.

“We dialed back production of the outgoing models in anticipation that the TLX would be here a little bit sooner, and we literally sold out of the TSX and the TL,” he says, pointing to this as the primary reason for the 1.8% decline in U.S. Acura sales through July.

“The back half of the year is going to be strong for Acura,” Accavitti believes, noting the TLX began arriving at dealers July 31.

Acura pushed back the TLX introduction from midsummer to late summer. No specific explanation for the delay has been given, but brand officials say it wasn’t due to the car’s ZF 9-speed automatic transmission. Another ZF 9-speed auto bedeviled Jeep last year, causing the Cherokee’s on-sale date to be delayed from summer to fall.
