AMG’s gullwing Wunderkind has only been on the market for two years, but the company’s already amending the basic recipe for the 2013 model year. Among a host of mild tweaks, the 2013 SLS AMG – which shall now be known as the SLS AMG GT – gains a bit more oomph underhood. Abroad, the SLS GT offers 591 hp, but U.S.-spec models should deliver 583 hp @ 6800 rpm.
