2018 Mercedes-Benz S-Class Engines Detailed Further

When Mercedes-Benz pulled the wraps off its updated flagship S-Class, it was noted that the carmaker hadn’t delved into too much detail on the engine lineup. While it had made mention of its (then) range-topping V8s and more pedestrian diesels, there was little mention of the brand-new inline-6 engines that the company had announced some time earlier, hotly anticipated to feature in the refreshed model range.

Earlier this week, further details on those turbocharged inline-6 mills were dropped. The S450 and S500 will employ the new forced-induction 3.0-litre straight-six motor, with the former capable of 270kW & 500Nm, and can be optioned with all-wheel drive. The more powerful S500 packs a more potent 320kW & 520Nm, though this model will be made available exclusively as a rear-wheel drive proposition.

As part of the continued wave of electrification, the S450 and S500 feature an integrated 49V starter/alternator, which can supplement the engine to provide an additional 16kW and 250Nm of boost when needed. Aside from the electrification, the inline-6 motor features an electric turbo that purportedly kills turbolag. With the new architecture, Mercedes-Benz claims a 22% improvement in fuel economy with the S500 by swapping out the old V8 with the straight-six, though this will be put to the test once we can get one for real-world testing.

Mercedes-Benz also detailed the S600 and S650 Maybach V12s, where the former will pack the same 390kW/830Nm as it did previously while the latter will see 463kW/1000Nm from the Mercedes-AMG S65. The new S-Class will be arriving on our shores in October, and we expect to glean more details on the lineup closer to that date.
