The N64!
Two turbos on the top! Look at the turbo placement, sick!!
Also notice the 2 water coolers

Cool, thanks for sharing. That's going to be some serious heat at the top of the engine compartment. They had better use some good insulation between the top of the engine and the hood.
It's way cool how the exahust location and the intake location have been switched. That's very innovative. They were thinking outside the box on that engine.

[QUOTE][Diesel tt V8. Why would they put the turbo's on top of the motor?/QUOTE]
It is not diesel. It is direct injection gasoline, all new BMWs and MBs will eventually get this injection style. More power, less fuel consumption.
As far as turbo location, I love it. Very innovative, only could be done with a clean sheet design since heads are reversed. Intakes are on the outside.
Turbo upgrades will be a snap. Everything is on top.
This might be how new AMG63 Twin Turbo motor will look like. There is no room on SL for conventionaly mounted turbos on the bottom.

Thanks for the correction. Direct Fuel inj.
The intake placement is pretty interesting and innovative(no heat).
However like one poster stated,"how do they keep the hood from burning up?"

Well I guess we'll have to see how well it works! The intake mani's look kinda small.
Only other advantage I really see here is that the exh mani's and the turbo's can be tinkered with.
Where is all the thermal heat gonna go when covered?
Interesting.

They are definitely production pictures.
I am ceratin that BMW has done proper R&D to make sure that there are no heat issues, including WOT runs on autobahn.

Can't wait for this one. BMW is going in the right direction. Now we just have to wait for their new designs to come out. This motor might be in the new 7 series. S63/65 killer.

Bravo, Clap Clap...
This innovative design has massive after market potential.
Not being a brown nose here... I'd thought I never say this but... Kudos to BMW!
I just hope MB is paying attention.

Thats the most beautiful engine I've ever seen, really. I think BMW has decided that they really need to take on MB at their own game, and of course this means the MBs will get even crazier!

BMW, has don't some funky things with turbocharging starting with their N54 engine (335i / 335xi).
The big thing driving non-M engine designs is fuel economy (and emissions) under the banner of efficient dynamics.
They started engine temperatures to modulate fuel econonmy and emissions. They deliberately run the engine hot to reduce internal friction and to improve fuel consumption / reduce emissions.
So heat is actually a good thing for the BMW turbo motor (to the extent they can control it). They lean out the engine and let it run hot in low load conditions.
So I imagine the reversed heads will somehow improve this.
Looks like they are also using 2 small liquid intercoolers too.

Sometimes innovative engineers get carried away and overlook the details as in the initial 335i design and initial production.
They also need to fire Bangle and come up with decent looking cars aside from the 3 series.

On my 335i they had to add oil coolers after a potential really disastrous build up of heat due to the excessive heat made by the twin turbos. All 335's from initial manafacture and up to about 6 months of production were affected. They really goofed on this one. I hope they take this heat build up seriously.

As a guy without an oil cooler, I am pissed at BMW....but they were not expecting people to beat the **** out of it....
Still for the cattle, the N54 is a great engine with many innovations.

The more I look at this engine the more I dislike the design. Yes it's very innovative but they are using a very small intake and very small exhaust system. Well, on second thought, the exhaust system isn't so bad but the intake looks very restrictive. I can't imagine the car running very well when it's not under boost.

The really don't want turbo lag and like little snails close to the intake. They are also going to take considerable measures to prevent these engines from being tuned to keep the ///M cars the fastest.
///M cars will keep normal aspiration for a while.

I think it's great that BMW is moving back into turbocharging. BMW is going to used forced induction on the M's. It's just a matter of time.

With twin turbos this size you don't really have any turbo lag even in the normal conficuration. Yeah, BMW took great strides to stop the tuners from modifying the 335. Give me a break.

The N54 can't really crank out more than 400 hp, with direct injection, the limit is in the piezo injectors.....this will be a big wall to climb. Even so, a tuned 335i can already smoke the new M3.
I am not sure if you follow BMWs, but they are religious on normally aspirated engines. The next generation of ///Ms will likely be an evo of the existing V10s with a big emphasis on weight reduction for performance (like Ferrari).
It is likely BMW will stick to normally aspirated engines unless F1 changes to turbocharging. The BMW engineers love to stick it to AMG engineers in areas like HP / liter.
