Mercedes-Benz GLC 43 AMG 2021 Mercedes-Benz AMG GLC 43 4MATIC

The Mercedes-Benz GLC is the brand's mid-size, five-seat crossover SUV. With a long list of lavish features and extravagant options, it is as sumptuous as any Mercedes sedan-with more utility.
The 2021 model only gets a few small updates, including standard keyless start and active parking assist. AMG models also benefit from standard parking sensors.
The lineup does get a bit smaller for 2021 due to the hybrid GLC350e being discontinued. However, the GLC continues to be offered with a coupe variant, which still sports four doors but features a far more rakish roofline.
The GLC can be had with powertrains that range from competent to absurdly quick. On the mild end of that spectrum is the GLC300's 2.0-liter turbo-4 that makes 255 hp. The power is churned through an 9-speed automatic that is also used with the higher-performance engines. Rear-wheel drive is standard, but only the base trim has it. All-wheel drive comes with other versions.
Stepping into the GLC43 means getting a 3.0-liter inline-6 pushing 385 hp to all four wheels. The GLC63 goes one step further by squeezing a 4.0-liter twin-turbo V-8 between the front fenders. It can be had with either 469 or 503 hp. Either way, expect 0-60 mph times of less than four seconds.
As expected, such performance won't make for the most efficient travel. The EPA expects the GLC63 to return just 15 mpg city, 22 highway, 17 combined. The GLC43 isn't much better at 18/24/20 mpg. The base model outdoes both by a wide margin with its 22/29/25-mpg rating.
Standard safety equipment includes automatic emergency braking and blind-spot monitors. Adaptive cruise control, active lane control, and lane-change assist cost extra.
The government hasn't tested the GLC yet, but the IIHS was impressed enough to call models with the optional adaptive LED headlights a Top Safety Pick.
