BMW dumps the 6 for turbo 4's

BMW can do whatever they want in my book, so long as they stay away from the V6 in production vehicles...

I am for turbo 4's

BMW created the most silky smooth 6 cylnder motors in the late 1960s. That's 50 years of evolution. The M50 and N50 are great motors, but they are... long. The best way to make a car handle is to have the motor as short as possible and as far back as possible. Which is better with a four than a six. The word of the day in motors is efficiency. The turbo four might not be as smooth as the previous six, but I am sure it will have as much torque (if not more) and will be more efficient. BMW won the 1969 ETCC with a 2002Tik (turbo), then won the 1984 F1 championship with a turbo four. Did anyone forget about the e21 Flying Bricks with monster turbo motors? I have been longing for a very long time for the return of a turbo four. Thanks BMW.

There's a reason that the BMW headquarters in Munchen is a Four-Cylender building. BMW wouldn't exist as we know it without the M10 series four-banger.

^This.

2.0L 4cyl. with 260 lb/ft @ 1250 RPM?? How is that possible?

Chevy hasn't used an lt motor since the late 90's, and the LS motors are only available in the higher end cars and/or in Most SUV's. It isn't really the same.

1997 was the last year for the LT motor. They was the good ol' SBC design but with reverse flow cooling, and a stupid opti spark...

Yes, I understand. But at 1250 rpm? That's more like a turbo diesel spec.

considering BMW made a 1500HP m10 engine with 1.5 L makes me guess that they know what they are doing.

That being said. bmw 4pots will be the new Boyracer wrx's

A lot of modern turbo cars produce peak torque from near 1000rpm all the way to to 4000+. Its nothing new. It started with the old 1.8t vw engine and LPT volvo engines from the 90s. With VGT turbos and DI its only gotten better.

Cause 135i and 335i's aren't already or used e46 m3's?

Huh. Guess I'm just used to looking at NA 4 cyl. peak torque specs in the 4000+ range. That and the 4 cyl. turbo cars I've owned seemed torque-less/gutless until 3000 or so. Regardless, that's a shitload of torque for a 4 pot. Me likes.

Here is chart of the 2.0t engine that VW/Audi has been stuffing into just about everything for the last few years. BMW took the technology one step further with its new engine but its not really revolutionary. Just an evolution of existing technology.


Also they will keep the N55 turbo as the optional engine. They're just replacing the naturally aspirated inline 6.

Nothing like a 4000lb sedan with a 4cyl to get your heart racing!

Right. Because a 4 cylinder F30 is going to weight 4000 lb. You're a genius.

lol? It makes more torque and teh same amount of power
