325HP Mercedes G400d Diesel To Slot Between G350d And G500
As the first diesel variant of the new Mercedes G-Class reaches European dealerships, word has it that there's another, more powerful diesel engine in the pipeline.
With 286 PS (282 hp) and 600 Nm (442 lb-ft) of torque from a 2.9-liter inline six-cylinder, the G350d isn't exactly lacking in power. After all, it covers the sprint from 0 to 100 km/h (0-62 mph) in 7.4 seconds and reaches a top speed of 199 km/h (123 mph). However, Mercedes-Benz seems to believe a more powerful diesel powertrain is needed.
Browsing through German insurance company HUK Coburg's data, MBPassionBlog has discovered a listing for a G400d model. In the entry, the engine features the same displacement of 2,925-cc as the G350d. That pretty much means it's the same OM 656 inline six-cylinder turbodiesel offered in a higher state of tune of 330 PS (325 hp). The torque rating isn't listed, but in the GLE 400d 4Matic the same engine delivers 700 Nm (516 lb-ft).

While the Mercedes-Benz G400d hasn't been officially confirmed yet, the fact that it is listed in insurance databases is a strong indicator it is coming. Thanks to the additional 44 PS (43 hp) and 100 Nm (74 lb-ft), the G400d should deliver improved acceleration and top speed performance.
More importantly, average fuel consumption isn't expected to take a big hit compared to the G350d which is officially rated at 9.8-9.6 liters/100 km (28.8-29.4 mpg UK) and 259-252 g/km CO2 NEDC. That should make the G400d a favorite among European customers who want more performance than the G350d can offer, but aren't willing to go for the thirsty G500 (sold as G550 in North America) V8 gasoline model.
