  1. BMW Reveals Quad Turbo Diesel 6 Cylinder

    BMW's i-6 diesel turns into a V-8 fighter

    By Jens Meiners, BIMMERPOST Correspondent

    Even though it has somewhat fallen out of favor on the US market, the diesel engine remains immensely popular in Europe - especially on executive sedans. In the interest of efficiency, BMW (and Mercedes-Benz) dropped out of the business of building V-8 diesels a few years ago - but Audi remained commited to the V-8. BMW's response was the tri-turbo straight-six, offered in the 5- and 7-series and the X5. Now that tri-turbo is being retired. But it makes room for something more awesome: A new i-6 diesel with no less than four turbochargers.

    At the Vienna engine symposium today, BMW confirmed its new, top-of-the-line oil burner. The new, top-of-the-line 3.0-liter i-6 will be fitted in the 750d xDrive; other model lines will follow. It will make 394 horsepower from 4000 to 4400 rpm; maximum torque is rated at 561 lb-ft, available from 2000 to 3000 rpm. On the road and fitted in the 7-series, it translates into a 0-60 mph time of around 4.5 seconds; top speed will be governed at 155 mph.

    The objectives were clear: More power, better response, high-revving capability, and creating a convincing "V8 fighter." Based on BMW's new modular engine layout, it is testament of that architecture's capabilities. The spectacular design features four exhaust turbochargers - two high-pressure chargers and two low-pressure ones. In terms of turbocharging, the main change was replacing the massive low-pressure turbocharger with two smaller common exhaust turbochargers; they came at a cost advantage and without a weight penalty.

    While the engine delivers immediate response and incredible high-end power, fuel consumption has been reduced by around 5 per cent. Maximum torque, by the way, is limited by the capabiliies of the XF 8HP 8-speed automatic. The engine, by itself, could deliver more. No wonder the diesel is so popular in Europe; we applaud BMW's move to raise the bar once more.

  2. BMW Diesels are great
  3. With 4 Turbos, I expected this thing to actually be powerful. Instead it is barely more powerful as an American Shit Eco-boost.
  4. almost four hundred horsepowers and 561 torques is quite a lot
  5. Well yah, I mean, it is a lot... I just expected more...
  6. I can't see why they need 4 turbos to achieve this.
  7. Low RPMs mean low horsepower. The torque is the more meaningful figure

    torque x angular speed of crankshaft


    angular speed (2π x rpm)/60 -> rad/s
  9. is power

    .... i think
  10. I feel insecure....

    Vanilla Icaaaa halp plox
