Mercedes’ mid-size luxury SUV, the GLE-Class, started life in 1997 as the Mercedes-Benz M-Class. The five-door crossover received two generational updates since its initial debut, the first of which was issued in 2005. The third gen arrived in 2011, and four years later, Mercedes gave it a facelift, revealing the update in January at the North American International Auto Show. With the facelift came a name change, with the M-Class badge retired in favor of GLE-Class, per Mercedes’ revamped naming strategy. Now, for the 2017 model year, Mercedes is replacing the GLE400 and GLE450 AMG with the new AMG GLE43. Essentially the same five-passenger performance SUV as the outgoing GLE450 AMG, the AMG GLE43 is framed as a stylish, high-tech, relatively quick SUV, with a dollop of family-oriented practicality and autonomous safety features spread on top.
