Mercedes in negotiations – with BMW?!
Well, well, well, Mercedes and BMW might just be about to make the biggest headlines of the year.
Bombshell news dropped last night that the luxury marque is deep in negotiations with its biggest car rival.
The news comes courtesy of UK-based publication Autocar, which cites Manager Magazin in Germany.
According to the reports, the two companies are already engaged in much-advanced, high-level talks.
And an announcement could even be officially made before the end of 2025.
But what exactly are they in negotiations for?
Essentially, Mercedes is negotiating with its rival to get hold of one of its engines.
The specific engine in question is the B48 turbocharged, 2.0-liter petrol engine.
Mercedes is negotiating for this particular engine because of what it can provide.
It wants the B48 engine because it is about to become Euro 7 compliant.
And being Euro 7 compliant means that it ensures ICE-powered cars can continue.
Why can’t the marque just use its own engines?
At this point, you might be wondering – surely the marque has a similar engine of its own?
That’s an excellent question – and the answer is yes, it does.
It currently supplies the M264-series of 2.0-liter, inline-four petrol engines.
But it is not known if the engine is capable of meeting Euro 7 regulations.
This would then translate into a greatly limited offering in Europe and the UK for the marque
Additionally, Mercedes recently debuted a 1.5-liter, turbo inline-four engine, the M252.
The problem with the M252 is that it is well-engineered for mild-hybrid uses.
What it is not developed for is for PHEV or range-extender usage.
It is this gap that the marque hopes a BMW-supplied engine would be able to fill.
What do you think of the notion of a BMW engine-supplied Mercedes in the future?
