Thought three turbochargers were overkill? Don’t tell BMW, which has reportedly unveiled a new 3.0 litre straight-six diesel engine that features – wait for it – four turbochargers, at the 2016 Vienna Motor Symposium on Friday.
According to Bimmerpost, the quad turbines – previously the reserve of the Bugatti Veyron – allows the oil-burning six-pot to churn out a nice round 400 hp between 4,000 and 4,400 rpm and a whopping 760 Nm from 2,000 to 3,000 rpm. For those counting, that’s 19 hp and 20 Nm more than the outgoing N57S tri-turbo mill that currently powers several M Performance models like the M550d, X5 M50d and X6 M50d.
Twin smaller low-pressure turbochargers replace the previous single turbine, and join two high-pressure units as before. These are said to result in a more responsive, higher-revving engine, while also cutting cost – and they come with no additional weight penalty.
As previously reported, the new engine will see its first use in the new G11/G12 750d, replacing another application of the tri-turbo engine. Fitted as such, it will enable the 7er to sprint from 0-100 km/h in about 4.5 seconds, while also returning around five percent better fuel economy compared to the previous mill.

BMW – the best engine in the market….and without cheating.
Not sure if serious.
Can’t wait to see more turbo breakdowns and recall
With so much trouble, why not go for electric turbo charger??
dumno! electric supercharger is the word.
hey john, no need to act like a smart alec insulting people like that. this is a knowledge community where comments should be meant to provide constructive knowledge based crtique. you can just kindly correct him for the reading benefit of others.
we really need to scrub this immature keyboard warrior mentality…kata nak negara maju..tapi otak tak nak maju…
otak mane ko… kan nama dia dumb?
Because they don’t work. Those electric chargers spin at less than half the speed of what a real turbo spins at.
Im still gasping at 760nm of torque…
Would be cool to see this engine here maybe in the 7er or she X5/6
i wonder how it sounded like with v6 quad-turbo
Wow! 760nm from 2,000-3,000rpm…WOW!!
