Mercedes-AMG 53 models pack turbo inline-six
We've known for nearly a year that an all-new inline-six cylinder engine would rest under the hood of Mercedes-Benz products. It's been more than a decade since Mercedes has built an inline-six, so fans of the brand celebrated its return. The 2018 S-Class would be the first model with the new engine, though not here in the U.S. (we're getting the V6). Automotive News reports that AMG is working on its own variant, and we're very excited to see what the performance division has in store.
We're not going to complain that cost cutting and parts sharing with four-cylinder engines brought about the return of the inline-six. Instead, we'll bask in the glory of silky-smooth revs and perfectly balanced combustion. In the S-Class, this new 3.0-liter engine makes 408 horsepower and over 368 pound-feet of torque. That's a significant step up from the already hearty 333 horsepower and 354 pound-feet of torque developed by the current V6. In AMG guise, the engine is expected to make about 430 horsepower.
Look for two turbochargers — one exhaust-powered and one electric — as well as a mild-hybrid 48-volt system. These new engines will kick of an AMG 53 range, presumably replacing the V6 in cars like the Mercedes-AMG C43 and E43. The first model with the M256 will be the all-new CLS-Class. Rumors suggest that the AMG variants of the E-Class coupe and cabriolet will drop the V8 altogether in favor of the inline-six. Don't worry, the beloved E63 sedan and wagon aren't going anywhere.
Everything with the 53 moniker will pack the new inline-six, supplementing the 4.0-liter twin-turbo V8 in all the 63 models. Since the U.S.-market S-Class is getting the V6, the new CLS-Class is likely to be the first American model with the new engine.

In all seriousness the naming pattern is ridiculous, if not as silly as Jaguar's. I think BMW got it right with theirs - it just goes up in increments of 10 from 20 to 60, sometimes with an "i", "d", or "e" to indicate the powertrain.

They might get there eventually, but are certainly not there now. There are plenty of 28 and 35 models still in the lineup.

Never did figure out what was wrong with making the numbers match engine displacement, it made logical sense. Put a t on the end for turbo, since that's the big thing now days.
Also looking forward to this new straight six. I'm wondering what it will sound like, if Benz will put a loud exhaust on it or not.

With these sorts of high end cars you need to be right into German car and engine codes and their odd marketing inconsistency. It's become a cool cottage industry among the fanboy sites.
E55 = AMG E class with the M113 ML55 motor.
E63 = AMG E class 6.2 V8 but they wanted to tell you it is a 6.3 to remind you about their first V8 which in fact was a 6.3... in 1963.
Now you have the latest E63 which is a 4.0 liter V8 but it makes 603 hp so, now you take out the zero and hey, now it's an E63

A long, narrow engine block like that will almost guarantee RWD and/or RWD-based AWD. It's difficult to use a transverse-mounted in-line six up front......Suzuki, with the (former) Verona sedan, is the only manufacturer I know of to do so successfully....and that was with a smaller 2.5L I-6 block.
