Pictures of the “C197” testing in the States were first spotted in August and now we have even more pictures of Mercedes response to the growing number of German supercars.

The “Mercedes Gullwing” has been referred to as the SLC numerous times, but we are expecting the production version to quite possibly sit under the AMG brand and sport a new name.

Six, seven or maybe even 8 gears might be in order. We can see a strip of LED, daytime running lights along the bottom of the headlight clusters. There also seem to be additional LEDs in the top section of the headlight cluster.

Another details that pops out are the large cross-drilled, slotted rotors. Those large rotors will be wearing a set of Pirelli tires. We’re also pretty sure, as with the on the 300 SL, a large Mercedes star will be dead centre on the grill.

The Gullwing is expected to be introduced at the 2010 Geneva Motor Show, with a limited run of sales for a period of two years. Production numbers will likely be around 6000 units a year and should carry a price tag of several hundred thousand dollars. We’re hearing horsepower estimates in the 550-650 range, with power expected to come from a forced-induction V8, or maybe even a V10.
