2014 Acura TL

Acura will debut the prototype of its 2015 Acura TLX sedan in Detroit next month – when it arrives in production form in the second half of 2014, the mid-size luxury sedan is set to replace both the TL and TSX in the company’s North American model lineup.

No visual indicators of how the car will shape up (the grey car in the photo is the current TL, and the red one, the TSX) save a simple TLX logo graphic, but the company is saying the car will feature more dynamic and sporty proportions, two new direct-injected powertrains and a host of tech.

The arrival of the TLX will clearly delineate Acura’s US sedan lineup, with a clear hierarchy of three distinct models, with the TLX – to be available in two-wheel drive and AWD forms – sitting in between the entry-level ILX and flagship RLX 5-Series/E-Class competitor.

More on the TLX Prototype, which was designed in Acura’s Los Angeles Design Studio, when the NAIAS kicks off in mid-January. Series production will be in Ohio, where the TL is currently being built.
