High tech world of modern cars, BMW, Mercedes Benz, Porsche

BMW, MERCEDES BENZ, Porsche and most modern high tech automobile contains or describe their efficient powerful engines with some words as twin turbo, twin scroll turbo, valvetronic, vanos adjuster and many more.

What do they mean?

For us, auto mechanics, for auto motive technicians and for the mechanically inclined may be not so complicated, but for the general public they are rather confusing names and descriptions.

Please let me try to help you explain the core description of all of this technical information.

Twin turbo means two turbo chargers, twin scroll is a single turbo with a special way of routing of the exhaust manifold which is more beneficial for a quick way to make the turbo more efficient without using multiple turbo chargers.

Many of this technologies are meant to do one thing and really one thing to make the modern lightweight piston engines more efficient and powerful at the same time.

Efficiency is the new buzz word for most manufacturers. They spend millions on research and development trying to minimize fuel consumption by reducing the internal friction by making the internal reciprocating or moving components to the bare minimum and reducing the pumping losses by installing turbo chargers.

There are no small details escape their attention, every single component has been lightened or redesigned to the absolute lightest possible, including using the lightest motor oil to minimize friction.

Unfortunately their efficiency comes at a cost of reduced life span compared  to the engines ten years ago.

What is Vanos and Valvetronic?

The Valvetronic system is a BMW variable valve lift system, in combination with variable valve timing. BMW’s Valvetronic system allows infinite adjustment of the intake valve timing and duration.

BMW’s Variable Valve Timing system is called VANOS (Variable Nockenwellen Steuerung). It controls the intake and exhaust cam timing (double Vanos) independently to achieve the best power while reducing emissions and fuel consumption.

We hope this sheds some light on this common use of technical descriptions by their respective manufacturers which perhaps somewhat confusing to the public.
