It Begins: C-Class Household Welcomes 4-Cylinder AMG Period with C43 AMG


First AMG within the W206 C-Class household, ushering in a brand new period of 4-cylinder AMG fashions within the c-class vary. The C43 ditches the V6 Biturbo from the W205 period for a brand new 4 cylinder turbo engine that launched on the A45 S AMG, the M139.

Nonetheless, on the C43 this engine comes with an electrical turbo, one thing borrowed from Mercedes F1. That is the second automobile after the 2023 SL43 to make use of this setup, and in the end the primary mass manufacturing engine to make use of an electrical turbocharger on this planet.

A couple of weeks in the past when the SL launched we reached out to AMG for some questions on this new engine. We mentioned the next:

1. A45 S engine vs SL43/C43 engine, what’s the distinction?
Reply: Identical engine, solely distinction is the A45 S has an everyday turbocharger whereas the SL43/C43 have a brand new Garrett e-Turbo.

Value noting that within the SL43, this engine is mounted longitudinally, as is widespread with Grand Tourers, however on the C43 and A45 it’s mounted transversely. The latter permits for extra cabin house and is simpler.

2. How does the e-Turbo work precisely?
Reply: Mainly you have got a 48v delicate hybrid electrical motor just like the one you discover on new vehicles, however as an alternative of powering stuff just like the air conditioner, right here the 48v electrical motor powers the turbo. This motor is simply used to spool the turbo earlier than the exhaust gasses take over, what this implies is you haven’t any lag like on an everyday turbo. You step on it and acquire an instantaneous enhance.

3. What does this imply actually?
– no lag
– you may lastly mount an enormous turbo to faucet the total potential of your engine with out worrying about lag
– fewer supporting mods for larger turbo
– with an everyday turbo, you lose a variety of vitality by the exhaust pipes in type of warmth and so forth, with an e-Turbo, the turbo will carry on spinning even after you step off the accelerator, harvesting vitality for the 48v electrical motor. That vitality will then be used while you step on it once more and wish to spice up. The cycle goes on.

4. Will this new setup (4 cylinder e-Turbo) be appropriate with a hybrid in future?
Reply: sure it is going to utilizing the E-Efficiency know-how.
– This solutions our fundamental query, that the following C63 will certainly get the C43 AMG engine however with an electrical motor, changing into a full plug-in-hybrid.

Additionally price mentioning that the C43 is now a correct AMG, the engine is constructed below the one man one engine precept not like the V6 from the earlier technology. It is without doubt one of the explanation why an A45 S is vastly totally different from an A35 AMG, the 45 makes use of a totally constructed AMG engine with a rotated block and turbos. The A35 then again makes use of an everyday A category engine constructed and completed by Mercedes.
