Next generation M cars are going turbo

I knew this was going to happen. It was matter of time. Now the fun really begins.


Tough emissions standards worldwide and soaring manufacturing costs in Germany are behind BMW's decision to switch from high-revving, naturally aspirated engines in its M high-performance vehicles to turbocharged direct-injection powerplants, beginning as early as next year.

The move, which could alter the character of BMW M models, places question marks over the immediate future of the M3's 4.0-liter V8 and the M5's 5.0-liter V10. Both engines will make way for forced-induction engines in coming years, according to high-ranking BMW sources.

The first M vehicle to make the move to the new turbo powerplants is the X6 xDrive M, which will challenge the Porsche Cayenne GTS and the Mercedes-Benz ML63 AMG.

Set to appear next June, the X6 xDrive M will be the first model to run BMW M's new twin-turbocharged V8. This engine is also earmarked for the next-generation M5, due out in late 2010.

Based on the standard X6 xDrive 5.0i's 4.4-liter 90-degree V8, the new twin-turbo unit is said to match the current M5's naturally aspirated 5.0-liter V10 for power at 500 hp, while providing as much as 516 lb-ft of torque.

This should be enough to provide the M-powered X6 with 0-to-60 mph acceleration of less than 5 seconds and top speed limited to 155 mph.

"In terms of overall performance, the new engine doesn't give anything away to the powerplant we run now, but it delivers much better consumption and lower emissions," a senior BMW M official told AutoWeek

That's going to be the trend among automakers: Turbo 4s instead of 6s, turbo 6s instead of 8s, etc., all in the name of fuel efficiency and improved carbon emissions.

Think of all the tuning capabilities though! Look at what the aftermarket has done to the 135i/335i/535i/x635i motor.

I don't see a problem here.... as long as its reliable and tested, it shouldn't be a detriment. If anything, it's got win written all over it.

Why not keep the V8 in the M3 and toss in 2 turbos?

Whats the life span of a turbo,,, maybee 100k if you let it warm up and cool down properly? Long term I dont like it at all, but you gotta love the torque of a turboed engine

life span is much longer then that with factory turbo cars. they don't run much pressure stock. its when turbos start running 15psi and higher does the life span start to really shorten (depending on the turbo)
i doubt bmw's 8psi does anything at all on life span to the turbos.
so my next m3 will probably be turbo.

Wtf... Are you guys serious? I've had a turbo car in my driveway that had 300K on it. Everything original, it saw 20psi a couple times and took it like a champ.

I do feel that having two variants of the same car is a good way to attract more(younger?) potential buyers.
I don't think its beneficial for the manufacturer to make two variations. It just becomes two of everything. Two time cost and time of development, crash testing etc etc... And then they have two versions to sell, one of which will probably be the lesser in terms of sales... remember car manufacturers are here to make money...
