The Mercedes SLS AMG might be in for the long haul.

Mercedes-Benz' upcoming SLC sports car might not replace the SLS AMG within the automaker's lineup as first thought.

Internally referred to as the C190, the SLC was originally thought to be under development as a replacement for the SLS AMG. However, a new report from Australia's Car Sales indicates the SLS will continue to be sold alongside the SLC.

Much like Mercedes sells the SLK as compliment to the larger and more expensive SL, Car Sales claims the SLC will be marketed as a more obtainable version of the SLS. The SLC is expected to ride on the same general architecture as the SLS, albeit with a shorter wheelbase and neater proportions more in line with the Porsche 911.

Like the SLS, the SLC is being fully developed by Mercedes' AMG division, which should help differentiate the car from the automaker's other sports car offerings.

The SLC AMG will likely break cover in 2015 with a price tag of about $110,000, or roughly half the MSRP of the SLS AMG.
