It's been over half a year since the current-generation Mercedes C-Class sedan was unveiled, but we're still waiting for the new GLC SUV to break cover. The two vehicles share a platform, but the current GLC, which debuted in 2016, still rides on old architecture. It was refreshed for 2019, but the time has come for a redesign to help Mercedes compete with the newer BMW X3 and Audi Q5.

We were hoping to see the new GLC at the 2021 Munich Motor Show, but Mercedes instead used the event to present new all-electric EQ models like the AMG EQS and EQE sedan as it prepares to become an electric-only brand by 2030.

The German automaker is still applying the finishing touches to the new GLC. Our spies have caught Mercedes testing an updated prototype of the new GLC, which was spotted near Mercedes' factory in Sindelfingen, Germany.

While the GLC remains wrapped in camouflage, it looks nearly ready for production. The final headlights and taillights are fitted and we get a clear look at the new grille. In terms of proportions, the new model looks slightly larger than the current one but with a longer hood. As a result, the new GLC should boast a sportier, more aggressive appearance and stance. And thanks to those larger proportions, the new GLC could be offered with seven seats like the GLB.

The mirrors have also moved from the A-pillars to the doors. Another cost-benefit of sharing a platform with the C-Class is the same engine options. In the US, the C-Class sedan is powered by a 2.0-liter inline-four rated at 255 horsepower and 295 lb-ft, paired with a nine-speed automatic transmission.

Interior tech from the C-Class should also carry over. As standard, the C-Class sedan (remember, the coupe is dead) is equipped with an 11.9-inch portrait touchscreen display and a 12.3-inch digital gauge cluster. We're expecting the new Mercedes GLC to debut early next year, possibly at the 2022 Geneva Motor Show in March.
