Mercedes-Benz in talks to use BMW engines for future plug-in hybrid, range-extender EV models – report

Mercedes-Benz is reportedly in advanced talks with compatriot and rival manufacturer, BMW for the latter to supply four-cylinder petrol engines to the Stuttgart-based brand, German outlet Manager Magazin has reported.

According to Autocar, a source within Mercedes-Benz has said that high-level planning and negotiations have begun for a range of its next-generation petrol powered models to use BMW-supplied engines. The agreement between BMW and Mercedes-Benz is being drawn up as a “strategic step to cut development costs,” according to the British publication.

The new 1.5 litre turbocharged four-cylinder petrol engine that features in the latest CLA, codenamed M252, is developed in-house by Mercedes-Benz in Germany but is produced in China by Horse Powertrain, a joint venture between Geely and Renault.

BMW B48 2.0 litre turbocharged inline-four cylinder petrol engine

The consideration of rival equipment is for compatibility reasons, Autocar cited Mercedes-Benz insiders as saying. While the M252 is suited for mild-hybrid electrification where it is paired with an eight-speed dual-clutch automatic transmission that houses an electric motor, it has not been engineered for plug-in hybrid or range-extender EV applications, which is where BMW could potentially come in.

This BMW unit is rumoured to be the B48 2.0 litre turbocharged inline-four, which is widely used in the current BMW and MINI model line-ups. The BMW B48 engine that is manufactured by Steyr in Austria is said to offer a wider scope of application compared to the Mercedes-Benz M252 as the BMW unit is packaged to work with longitudinal and transverse layouts, Autocar wrote.

Should the rumoured arrangement proceed, this will be the first time that the two rival German brands would share an engine. The potential partnership could also extend to production hubs globally for the two manufacturers, and a shared engine production plant in the United States could also help the brands get around tariffs for products imported into the US.

        Which BMW’s PHEV is worth copied by Mercedes Benz?

        The BMW i8 had a combined output of 374 hp and 570 Nm of torque, with the 1.5-liter 3-cylinder petrol engine producing 231 hp and 320 Nm, and the electric motor adding 143 hp and 250 Nm.

I tried your so call God level BYD and BMW i4 and i5 side by side at Sime Darby Balakong last week. No comparison la. BYD handling bounce and float like hell. tekan minyak hesitated so long and reluctant to boost no wonder lose to Tesla in sprinting test. half baked tech. The aircond hot like hell 5 mins in the car still so hot pity those owner bare the pain diam diam semua. The safety system always kacau one motor pass by in front the car slam the full brake lucky I got wear sit belt. The ev motor suppose silent but in reality sound weird the sales say because a lot ppl test need service thats y. what?! shitty car. BMW i4 and i5 feel omg refine with cold air cond and good handling and silent motor. Thats the different between real car manufacturer vs heabily subsidies brand and cina gov is crackong down on BYD misusing subsidy. cant afford go home la half baked cina buyer. ppl like u who have no class barking here make the cina brand look bad and I rather buy shitty tesla over your shitty king cina brand if I want cheap ev.

      isn’t the reality opposite where merc high performance engine tech is superior? for example they have the 2.0 turbo in amg a45, 1.6 F1 engine in the one-one both of which don’t have any bmw equivalent

      Why would he, merc have been using Renault engine for awhile, it’s an upgrade that they choose BMW instead. The pure Mercedes engine reserved for high-end product only.

    It’s not like current BMW PHEVs have a reputation for reliability either.

    No modern cars are good ,reliable and durable at all including german cars. bmw engines are nightmares after 60k to 80k km of usage with countless mechanical faults or repairs and electronic failures.
    mercedes using bmw engines will never be the mercedes as before ,imaging karl benz crying and sadden by his invention,,

    mercedes is chasing for more profits for the shareholders rather than giving back their purchasers what they pay for the brand. famous for its good long lasting durable powerful engines,

    buying a mercedes is aka like buying into nissan and vw quality with premium high price compare to the latter that make no sense .at all as most believe is a crap decision.overall,
