Back in January, we showed you spy shots of a 2014 Chevy Impala with a grille that differed from the two-bar unit that debuted on the “regular” model. For a while, we thought the unique flat-looking and winged grille was part of the aerodynamics package for the Impala Eco mild hybrid model. But we were wrong.
Instead, it seems that the grille is added to the 2014 Impala only when the vehicle is equipped with the Full-Speed Range-Adaptive Cruise control, at least we’ve come to know that much in configuring the new Chevy full-size sedan online.
In addition, GM Authority reader Cameron told us that the grille has appeared in the GM Electronic Parts Catalog, and that it three RPO code identifiers associated with it, including:
- LFX — the 3.6 liter V6 engine that is the range-topping powerplant in the 2014 Impala
- KSG — Full-Speed Range-Adaptive cruise control
- 9H8 — Auxiliary Daytime Running Lights
As such, it seems that the unique grille is only on those 2014 Impalas equipped with the adaptive cruise control (KSG), and isn’t part of the Eco hybrid model.
Update: GM just confirmed that the Impalas with Adaptive Cruise Control (ACC) utilize the black hourglass-shaped grille due to the radar technology in the vehicle. The radar for the ACC is located on the grille.
Of note is the fact that the Impala’s platform mate — the Cadillac XTS — does not utilize a different grille when equipped with ACC.
