And we’re pretty sure we know how much power it will make.

If by now you don’t know Mercedes-Benz will soon kill off its C-Class and E-Class Coupe and Cabriolet models to create a new model called the CLE, it’s probably time to open your CarBuzz app a bit more frequently. Our spy photographers have spotted the Mercedes-Benz CLE Coupe and the Cabriolet version testing on multiple occasions, but this most recent run-in on the Nurburgring revealed a new detail.

One of the prototypes wore a yellow sticker, signifying that it is a plug-in hybrid. Of course, the second door for the charge port is also a dead giveaway. Mercedes likes to place its charge doors on the right side of the rear bumper for its sportier model, as evidenced by the GT 63 E Performance, and the CLE continues this trend.

Placing the charge door on the rear may seem like a convenience feature (with easy access when you back into a charger), but it’s more likely a cost decision. It’s cheaper to produce different plastic bumpers for the gas and PHEV models than create a different sheet metal part on a fender. Since two-door models like the CLE (especially PHEVs) are low-volume, this is a smart move for Mercedes.

As for the powertrain, we know very little about this new electrified CLE. The base CLE 300 is expected to arrive sporting a 2.0-liter turbocharged four-cylinder engine producing the same 255 horsepower and 295 lb-ft of torque as the C300 sedan. If the CLE follows the same pattern as the C-Class, there will also be a CLE 43 AMG variant with a mild-hybrid system contributing 402 hp.

Though it hasn’t been fully revealed yet, we know the upcoming C63 AMG with add a PHEV system delivering up to 670 hp. Based on the wheels, bumpers, and other design elements, this CLE test mule does not appear to be a 63-branded AMG model. Therefore, it seems far more likely that this two-door model will share a drivetrain with the C300e PHEV. That model produces 313 hp and 405 lb-ft total, yielding a 6.1-second 0-60 mph time and a 62-mile electric driving range (on the WLTP testing cycle).

Mercedes has been testing the CLE since 2021, so we wouldn’t be surprised if a reveal happens by the end of 2022. Based on previous product cadence, we doubt that this PHEV model, likely called the CLE 300e, will be shown off simultaneously with the gas-powered model. Aside from any AMG models, it seems like there aren’t any more CLE variants left to spot.
