Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 SLS AMG.
Within the 2011-2014 model range, the 2014 Mercedes SLS AMG is a passenger car that stands out for its sharply improved reliability metrics. The vehicle logged just two total owner complaints—both centering on the air bags—alongside two recalls, demonstrating a highly concentrated rather than widespread issue profile. This low volume positions the 2014 model as the least problematic year in the platform's history, a notable drop from the seven complaints recorded in 2012, meaning late-model examples offer the most trouble-free ownership experience within this generation.
