Acura TLX test vehicle

Acura doesn't tend to do concept cars these days that don't foreshadow a specific upcoming production model. The ZDX prototype of 2010 previewed the production version, as did the ILX and RLX showcars of 2012 and the MDX of 2013. The NSX concept is on its way to production, as the SUV-X concept is likely to do as well in the coming years. So when Acura revealed the TLX prototype at the Detroit Auto Show a few months ago, we all but knew it would only be a matter of time before that, too, would be produced. And here it is.

Spied all but completely undisguised while undergoing testing, this pair of TLX prototypes (one in white, one in black) looks almost identical to the show car. You might spot a few minor tweaks here and there – the strip of LEDs in the lower front bumper have been replaced by round fog lamps and some of the chrome accents are missing – but by and large, we're looking at the same vehicle we saw in Detroit earlier this year.

The finished production version of the TLX is expected to debut at the New York Auto Show next month, after which it will replace both the TSX and the TL, slotting in between the smaller ILX and the larger RLX in Acura's sedan lineup.
