There has been widespread speculation of the move in recent days and earlier Tuesday, in Australia, GM officials said no decision had been made.

Porsche 911 GT3 RS

Porsche has released pictures of the most intense 997 yet, the GT3 RS. Due to be released in spring next year in North America, the RS produces 415PS from its naturally-aspirated 3.6l flat-six, enough for a 0-62mph time of 4.2 seconds. Power is sent through the rear wheels only, whose surrounding shoulders widen by 43mm to accommodate the extra track.
