Interview: BMW M Head of Engine Development Details F10 M5 S63Tu Engine

[pride355]

So this M5 has M specific twinpower turbo engine unlike M modified 1M engine. I'm curious about the difference of throttle response of the 2 engines.

[positiveions]

and I thought E=MC2 was a complex formula. sheesh..
Nice to see brains worked closely to create this ///MMMMean machine

A byproduct of turbocharging is a muted exhaust note. Just a fact of life.

I bet it's because of how they designed the bottom end of the motor especially the bearings.

simply incredible...on super car proportions...lots of engineering and man hours we'll have to see how it performs and holds up as several owners will be tracking these cars.

Ferrari owners don't seem to mind...

[seoulmandmd]

This was great. I wish we interviewed him for every engine that comes out.

[username604]

I love mine too, my sweet sweet inline-6!

Ferrari's also have a flat plane crank, which totally changes the sound of the engine. They are the best sounding engine's out there.

you are correct

I wonder if we can find out what is the make-model of the turbochargers that are used in the S63 and S63TU...

They are Honeywell twin scroll units built to M specifications (still stamped Garrett, lol)

This engine has Valvetronic and the response is a bit quicker feeling bc it is so much stronger. With the M5 it also depends on the mode.

M-Power.com is the internal publication of M Gmbh so you can be assured they will run features like this with each new development- there is more coming...

M engines used 10W60 because of the high engine temperatures so they needed high viscosity oil to keep everything lubed up properly when running hard. If not, the oil would get too thin and not protect optimally and also increasing oil consumption.

This M5 engine is amazing and I have no problem believing it will run proper cool. No classic hot running turbo's or high oil temps (N54)

Water cooling the DME and charge air is also a question of space, water takes a lot less space then air and it's crowded up there already, therefore giving much better cooling efficiency/space. But it's expensive...

Oh, and I would be careful if you would ever lower this car as you won't only be destroying suspension geometry, you don't want to damage that oil cooler either!
