The GLC43 Coupe enters a new generation for 2024. New looks accompany an interior with an even larger digital display, and the updated powertrain—which replaces the outgoing V-6 with a turbocharged inline-four—gives the GLC43 Coupe a bump in horsepower and torque. A 671-hp GLC63 S E Performance plug-in hybrid joins the lineup for 2025.
