Mercedes-AMG to Drop Four-Cylinder for Inline-Sixes and V-8s (caranddriver.com)

(Saturday June 28, 2025 @11:34AM (EditorDavid) from the car-talk dept.)


"Mercedes-AMG is transitioning away from the four-cylinder plug-in hybrid powertrain," [1]reports Car and Driver , "and back towards the inline-six and V-8 powertrains more traditionally associated with the brand."

> That isn't to say that AMG had a change of heart concerning the merits of the four-cylinder powertrain, but rather that the automaker is responding to customer criticisms. "Technically, the four-cylinder is one of the most advanced drivetrains available in a production car. It's also right up there on performance. But despite this, it failed to resonate with our traditional customers. We've recognized that," [2]a source at Mercedes told Autocar ...

>

> Car and Driver also spoke with AMG chief Michael Schiebe at the reveal [3]of the AMG GT XX electric concept car ... Although the four-cylinder may be on its way out, Schiebe did say AMG remains committed to plug-in hybrids. "There are a lot of advantages of combining electric motors with combustion engines," Schiebe said. "We want to offer different kinds of drivetrain opportunities on the combustion side to our customers, so they can choose for whatever purpose they want to use the car."

>

> Much of the criticism of the C63 and GLC63's powertrain was focused on the lackluster sound when compared with the symphony of a V-8. The M139 drew our ire for sounding "reedy" and "buzzy" in [4]our test of the current C63 . The C63's hybrid system also brings the car's curb weight up to nearly 5000 pounds, meaning it didn't provide a meaningful performance boost over its V-8 predecessor despite offering significantly more horsepower....

>

> AMG wouldn't confirm exactly when the four-cylinder will be phased out, telling Autocar that it will remain in production for the time being before "eventually" being replaced.

The only thing that resonates is the empty brains of vroom-vroom lovers.

The AMG badge typically meant you either had a tuned V8 or even V12. And it wasn't for drag racing or making noise. It meant you wanted to cruise comfortably at 155+ on the autobahn. They had a nice respectable sound. The badge started to get watered down with AMG packages only having some fancy wheels. It's still amusing to me how many Cannonball run times were set with German sedans.

And those who had to drive up a hill. Or merge onto a highway safely. Who think that a lawn mower engine with turbo is not a good fit for an auto. :-)

Please dear lord, let the trend to replace decent inline 6 cylinder engines with 4 cylinder lawn mower engines with turbo bolted on, be reversed.

I owned a Volvo with their inline 6 engine and it was great. Ran smooth and the seats were super comfortable. Unfortunately the rest of the car was garbage with numerous leaking fluids, electrical problems, and rotted rubber hoses in the emissions control systems. Also had an old Jaguar with the famous 4.2L and it was equally nice to drive.

My daily driver now is an Alfa Romeo and they managed to squeeze 280hp from a 4 cylinder engine. It’s fast enough to be fun but it’s certainly not smooth unde

I have an old BMW inline 6, no turbo, that gets 21 city and 33 highway. It's rated for 24 highway but I suspect the German designed engine is not optimized for 55 mph and performs better at 65-70 mph. :-)

Peak power vs average power (Score:1)

by RightwingNutjob ( 1302813 )

Was looking into a hybrid toyota suv a while back.

Gas engine was standard 6 cyl 270 hp.

Hybrid was a 4 cyl 180 hp plus 60 hp motor.

Not much of a difference in peak power but quite a bit of difference once the battery runs out and some of that 180 from the gas engine needs to be bled off to charge it up.

Not an issue with city driving but not that great with overtaking on a slight uphill grade at highway speeds.

Remember test driving a 4 cyl gas toyota suv with the wife a few years back. Tried it on one of thes

That's actually very interesting, since people keep insisting hybrids have no drawbacks. If they can't go up a hill then they are going to take a dangerously long time to accelerate to passing speed on a single lane highway.

4 is efficient. 6 is smooth. 8 is loud. All can make lots of power with turbos and more with hybrids.

And they all suck compared to evs.
