BMW 535i GT: New Single Turbo VALVETRONIC N55 Engine
#1
Clickity Click Click
Here's a detail of the new BMW 535i Gran Turismo that deserves to be duly noted.
The 535i GT features BMW's new TwinPower Turbo with High Precision Injection and VALVETRONIC technology, a single turbo with twin-scrolls that puts the squeeze on the 3.0 liter straight-six gasoline engine, internally referred to as the N55 over at BMW.
This engine, as opposed to the twin turbochargers of the N54 version, is a first for BMW, coupling that single twin-scroll turbo with High Precision Injection and the variable valve management of the VALVETRONIC system. The 4.4 liter V8 that goes into the 550i GT still gets a twin-turbo but that 4.4 liter may be getting this new tech-upgrading for the upcoming X5M/X6M versions.
Distinguishing the N55's performance from its predecessor includes a broadening of the torque band, the 400 Nm now peaking pretty early at 1,200 rpms, and extending all the way to 5,000 rpms. The N55 also has a map-controlled oil pump which helps conserve energy, a first for a turbocharged engine, and the improved engine management gives it a better fuel economy and CO2 emission rating than the N54.
Naturally, speculation goes to the obvious next step, that BMW will introduce VALVETRONIC and High Precision (Direct)-Injection on a twin-turbo version of this 3.0 liter straight-six and dial the horsepower up to 360.

Hmmm...
...well maybe someone can tell us whether the F10 will have this engine and be called the 535, or have the 740i's engine and be called the 540i?

Sounds very interesting, but all these new technologies also sound very complicated. Which would mean even less reliability in the long run.

that is true. in turn, people will be more likely to sway away from buying a used non-warrantied bmw, new car sales and CPOs are now doing better
What you save on gas will be less than what you will spend maintaining these engines.

All this fuss about fuel efficiency is killing the reliability of these engines.

i agree. i dont believe technology is at a point where it is benificial to your pocket to purchase a highly effecient vehicle... yet

screw high effeciency vehicles. i dont own a smart car because:
if someone is willing to put their children in a smart car, they are crazy. and i dont even have children... i wouldnt put my dog in a smart car!
