EPA Filing Reveals Key Specs Of Some Upcoming Mercedes-Benz Models

The United States Environmental Protection Agency (EPA) has received an application from Mercedes-Benz for the certification of its 2024 model-year lineup. The document, consisting of 86 pages, has provided some interesting insights into the brand’s upcoming models.

Here’s a quick rundown of the key details of some upcoming Mercedes-Benz vehicles as revealed by the EPA documents dug up earlier by the folks at Car and Driver:

E-Class All-Terrain to be Launched as E 450

As per the recently released EPA docs, Mercedes plans to introduce the E-Class All-Terrain in the US under the E 450 badge. However, it appears that the standard E-Class Wagon won’t be making its way to the US market, leaving buyers there with only the option of the more robust and elevated body style of the auto.

Upcoming Mercedes-Benz CLE Model Seemingly Confirmed

The filing naturally leaves out both the C-Class Coupe and E-Class Convertible. This only confirms their consolidation into a single range, the CLE.

Known as the “C236” codename, the range will fill the gap left out by the axed models. The new CLE Coupe and CLE Convertible models are set to be made available in Benz-branded four-cylinder 300 4Matic and six-cylinder 450 4Matic versions, along with the AMG 53 performance variant.

Next-Generation GLC 63 S Listed as a Plug-In Hybrid

The next-generation GLC 63 S is also mentioned in the document. What’s so interesting about it is that it will include a plug-in hybrid unit with “E Performance” branding. The lesser GLC 43 will also be offered in its four-cylinder guise, similar to the SL 43 roadster.

Possible Changes to the E-Class AMG Models

The AMG C-Class is about to get downsized, and rumors suggest that its bigger brother, the E63, will also lose some cylinders. The flagship E63 is expected to receive a hybrid six-cylinder, but nothing is official yet.

Finally, sources claim that Mercedes is contemplating a reduction in the number of cylinders in its E-Class lineup, similar to the downsizing approach used in the AMG C-Class models. Rumors suggest that the flagship E63 will also undergo this downsizing process, albeit not to the same extent. While there is no official confirmation from Mercedes-Benz, it is speculated that the E63 may feature a hybrid six-cylinder engine.

Final Thoughts on the Upcoming Mercedes-Benz Models in 2024

Mercedes-Benz is set to release some exciting models by the next calendar year, as revealed by the EPA document. From the looks of it, the absence of the regular E-Class Wagon in the US market will hardly be felt because it will be compensated for by the E-Class All-Terrain. Likewise, the SUV-loving market there has since moved on from wagons long ago.

The all-new CLE is also an interesting addition to the lineup of the upcoming Mercedes-Benz models in 2024. Lastly, with the GLC 63 S and GLC 43, Mercedes-Benz is continuing its focus on plug-in hybrids and four-cylinder engines for its best-selling SUV range.
