The new 911 Turbo will keep the same 3.8-liter horizontally opposed six cylinder engine as previous models, but it will have a new boost thanks to a complex tri-turbo setup similar to what BMW is using in the M550d xDrive and X5 M50d models, among others.
The system employs one smaller turbocharger and two larger ones. The smaller spools up more quickly at lower rpms, delivering an initial power boost that carries smoothly into the second and third larger units.
Although the horsepower ratings aren’t certain yet, the new system is expected to boost the 911 Turbo from 495 to 525 horsepower, which is quite close to the 530 hp 911 Turbo S.
Porsche is currently completing testing on the tri-turbo setup inside their 991, though further details can’t be that far off given that it’s slated for the 2013 model year.

Rumors are now spreading rampantly since BMW released its teaser video of the first-ever BMW M Diesel in the form of their X6 crossover. It is now widely believed that the X6 M50d will come with a tri-turbo, six-cylinder diesel powerplant pushing out 381-hp with a healthy 545 lb-ft of torque.
The folks over at BMWBlog are also reporting that the X6 M50d will go 0-62 mph in 4.9-seconds and that production of the model will begin April of 2012. An option for the X6 M50d also leaked out; the M division will also offer a revised front hood.
Perhaps even more interesting is that BMW’s M550d xDrive will feature the same powerplant, making it go 0-62 mph in just 4.7-seconds and could get 38-mpg. The M550d is expected to go into production in March 2012 but will only be offered in Europe. Whether or not the X6 M50d shares the same fate is unknown, but given how slowly diesels are being embraced in America, we shouldn’t hold our breath.

Over the last few years, diesel technology has taken a huge leap in technology. So much so, that a diesel powered car is the preferred choice of weapon for any endurance race.
With their success on the track being recognized, it’s only a matter of time before fast diesels make their way into road cars, and BMW seems to be jumping at that.
According a leaked document, BMW is preparing to offer a model that will wear the badge: M550dX. While not a true M model, it also hints that this is more than just an M-Sport package. Instead, it will likely be the first ever diesel designed by BMW’s M performance division.
As the name suggests, it will be all-wheel drive, and will likely use the new 3.0-liter, triple turbo-charged (yes, you read right) motor that produces 395-hp.
There is no confirmation from BMW at this point, but the possibilities certainly are exciting. Americans have never been fond of diesel passenger cars, but slap a Roundel on the front and an M badge on the back and it’s sure to change more than a few minds.
BMW is working on a new engine for its diesel cars, and it’ll be packing three turbos for the X6 and the 7-Series—just like the next M3.
The Tri-Turbo will be a 3.0-liter six-cylinder engine with more turbochargers than BMW’s twin-turbo models, but less than Bugatti’s quad-turbo engine. Combined, power of these pinwheels will be between 350 and 400 horsepower.
The engine is currently being tested in the 750d and 750ld flagships, which will be introduced at the Frankfurt Auto Show in September, and Europeans will be able to three-ball it starting next spring.

With the 2012 M5 now revealed in all its turbocharged glory, the auto tabloids have switched focus to the next-generation M3.
While the V8 has long been rumored as dead, the latest reports indicated BMW will switch back to a straight-six engine, opting instead for turbochargers to make up the difference for the decreased displacement. In fact, the next-gen M3 mill will drop almost a quarter of its size, down to 3.3-liters. The straight-six will then be blessed with not one, not two, but three turbochargers – one of which will be electrically powered. Rumors of this same setup on an X3 M model have surfaced before and if true, let’s hope the engineers in Munich have advanced electric turbos beyond the eBay kind.
