Can One Turbo Be Just As Good As Two? 2011 BMW 335i Series Test Drive

Ha!

Ja ja ...it is not going to happen man...

it's not going to happen because they innovate FAR FASTER than the competition...

- regular performance upgrades
- timely refreshes
- regular all-new existing models (5, X5, X3, 7, etc.)
- completely new models (X6, 5GT, etc)

and the cars all performance remarkably well withing their respective classes!

Its news when there is a major change (and seemingly a backwards one) to the engine in the best sports sedan in the world.

And if you haven't been paying attention, MB and BMW are now kicking some serious butt on the world economic front. Germany is basically not in an economic depression anymore (while the rest of the world continues to slide deeper and deeper into Obamanomics) due solely to the economic power of its auto industry and Germany's ability to be an export superpower.

You and a lot of other people who post on this site either need to get better informed or stop posting becauase all of your lame comments are getting pretty old.

And PLEASE quit complaining. If you don't like the content of this site, then go somewhere else or start your own site and then you can fill it with whatever content you feel is best.

nice...equal power, max torque at an even lower 1200rpm, and a bump in mileage. bmw really does build remarkable engines. i miss my 335i....

Sure it can work. I have seen others moving from twin turbo to single turbo setups. The primary reason for using twin turbos is to keep the turbos smaller minimizing turbo lag by reducing spool up time while still maintaining the required compressed air flow- - - but there are drawbacks compared to single turbo system. A single turbo provides:
- A more compact design with less piping and system complexity
- Lower heat soak which robs the engine of horse power negating the purpose of having a tubo
- Lower engine bay heat for improved reliability of all components
- Lower maintenance costs
- Lower costs of production

A well designed single tubo system, if designed to keep turbo lag to a minimum, trumps a duel tubo system for most applications.

The single turbo vs twin turbo debate isn’t always about the real numbers, but the mentality that if one if good, two must be better. Right???

Perfectly said terry.

and last but not least: weigt reduction = less nose heavy = better handling

Terry989: Well thing two are better but also that means more parts, less relaibility, and so on....But in this case they improve the previous engine numbers..that is a good engineering. What about 4 (quad turbos) yes more is better and also more expensive...like the Veyron. More turbos is less lifespan for hte engine, So I think this is a good move.

the number of turbos has no direct impact on the lifespan of the engine, the amount of boost that they provide however does.

2 mpg better? Pretty good.

Yes, but Twin Turbo SOUNDS sooooooo much better than single doesn't it?

No impact on lifespan of the engine is right, but still more complex. (problems)
