New family of BMW engines to share as many as 60% of components

The launch of the new 2.0 liter four-cylinder TwinPower engine was only the beginning for a new family of BMW engines. Most of the engines available today in the lineup will be redesigned so they can share far more parts.

Utilizing a new common 500cc per cylinder base design which also uses Direct-Injection and Turbocharging, the new family of engines are more efficient and align with the EfficientDynamics strategy, and will range from three to six-cylinder capacity.

Fuel intake and exhaust systems will share components based on the fuel type, gasoline or diesel. Mounting points for the powertrains will also be standardized for both transverse and longitudinal installations.

P900744121 655x436For Automotive News, Harald Unger, head of development of BMW inline engines, “Our goal is to have 60 percent of components shared between engines based on fuel type, and 40 percent commonality between gasoline and diesel engines.” Currently, some of BMW’s engines are derived from other engines but few parts are shared.

Same Automotive News says that BMW’s engine program could mean a consolidation of suppliers. For example, Unger said two companies, Schaeffler Group and Hydraulik-Ring, supply variable valve timing mechanisms for gasoline four- and six-cylinder engines. In the future there may be just one, a measure that could keep costs in place by giving BMW more leverage over the supplier. In 2010, BMW produced more than 1.4 million four- and six-cylinder engines.

“We have set the engineering design for components, but it is up to purchasing to determine which and how many suppliers will be awarded the business,” Unger says.

Future Twin-Power Turbo diesel engines of three, four and six cylinders will share fuel injectors, turbochargers, pistons, connecting rods, chain camshaft drives and noise-suppression covers. Additionally, Twin-Power Turbo engines will be used in hybrid powertrains. These applications explain the need for a 1.5-liter three-cylinder engine rumored to be available in the 2014 BMW i8.

But BMW enthusiasts remain an important demographic for BMW and Auto News confirms that the Twin-Power Turbo program will not influence V8, V10, and V12 engine programs.

     Horatio, the BMW v10 is dead with the old, beautiful and unparallel, M5 & M6!

    This is the start of the end of BMW as a performance sedan. Sharing engine parts is the approach American manufacturers use. Compatibility takes precedence over performance, this has started with BMW’s adoption of turbos as their base engine along with turbo lag. Audi may take this segment after all.

       BMW was going down long before this.

      They have nothing for example to challenge the dominance of the Lexus CT200h, HS250h or the ES350 in the US market. Nothing. And it’s hurting them badly. Instead they built completely useless cars like the 5er GT or that new M1 Mario kart.

      BMW needs to focus on what people want:

      -minivans
      -station wagons
      -FWD performance cars with turbo engines
      -reliability, unmatched performance and quality and value (look to Lexus, Acura and Infiniti for that)
      -4-door coupes

    It’s certainly a good news for the shareholders – the interview was given to Auto News, not to a car magazine – but not sure it’s a good one for customers.
    1st, they’ll expect BMWs to be cheaper in the future – which is the case for the X1 28i – but the high end model buyers want exclusivity. Instead of the best I6 N/A engines, they’ll get a Turbo I4 or a Turbo I6 which is the same as the I4, “simply” 50% bigger. It’s also good news for DIesel buyers but not so good for petrol buyers.
    BMW made already that mistake with the M5, fitting it with a slightly enhanced version of the X5M’s. They should have at least released the X5M after the M5, cause instead of having a SUV with the same engine as the M5, they got a M5 with the same engine as a SUV… Where’s the exclusivity in here?

    Why wouldn’t they do this for the V8 and V12 engines?  V8 is just two inline 4s and the V12 is two inline 6s
