Why in the world would they use a Twin-Turbo Charger in the new 335i???

Question

Im sure the newest innovation from BMW will compete as well if not better than its predocessors however WHY WOULD A COMPANY KNOWN FOR NATURALLY ASPIRATED ENGINES use Twin Turbo Chargers, its the end of something ultimate as I see it. . .

Answer 1

Look back in time this not BMW's first turbo car. Up till now they have been able to get the power they need with out it but in an ever increasing game of "lets push the power up" game the turbo is a great solution. As for it being the end of the ultimate I know folks who believe real BMW's have round tail lights all the rest are just cars! So if you want to stick your head in the sand, or run to the king because the sky is falling have a nice time!

Answer 2

If it is done correctly, gas mileage may improve, since the turbo only really engages when you demand more power. The rest of the time, itis just floating along for the ride. The problem comes in if the engine was not engineered for the additional power these items inspire. When you say twin turbo's I assume you are talking about a straight 6 (like a BMW) or V6 (like Audi) THe Audi TT originally had a sequential twin turbo on it. What kind of car are you referring to??????

Answer 3

BMW wanted to stick with their smooth, torquey inline 6-cylinder engine, but they needed to get more hp out of it to compete with Infiniti and Lexus, which use V6s. BMW has always rejected turbocharging because of turbo lag. However, the new twin turbos are tiny and have virtually no lag, making them totally acceptable by BMW standards. Now you've got a 3.0 liter inline 6 that's as much a BMW engine as any, but it's got a substantial hp kick (around 300 hp) that's actually better than the e36 M3 and only a little behind the current M3. Pretty awesome.

Answer 4

BMW's system is very efficient system. One small turbo and other is slightly larger. At low rpms ur smaller one comes on for low speed power and as RPM's grow the larger turbine kicks in to give power on top end. With turbo help, u can keep engine size smaller and develop larger amounts of power without having to add extra weight from a larger motor. With the help of turbines differences in altitude and barametric pressure do not influence motor output as much. Also, being a BMW fan myself, I've driven the 750i and the 740i and can tell you the extra motor in the 50 only give it a little more power, and the weight kills the turning ability and makes it plow into corner like a turd. So having the extra power from the turbined smaller 35 series without having to go to the size of a 4.0 to 4.5 to get the same power and keeps the car much better balanced. All things BMW aspires too.

Answer 5

The company feels that in order to compete in today's market of smaller much faster cars they need to expand their potential. This is only one of the ways they are trying. In the last couple of years BMW has been taking a beating from Audi their #2 rival (next to Mercedes Benz) for full details about the world of turbo-charging see the provided reference site. Hope this helped.

Answer 6

To keep it simple and pretty much the way Jeremy Clarkson said it: the one turbo gives a greater boost but results in turbo lag. So they put in a smaller turbo that has no/less lag and when it hits a point it swaps to the bigger turbo 4 power

Answer 7

Politics, costs, reliability etc. Its a lot easier and cheaper to bolt a turbo onto an existing 3 litre block than it is to develop a new 3.5 litre block from the ground up.

I'd be willing to bet that you can't tell that the car is turbo charged when you drive it.

Answer 8

They couldnt cope with other turboed engines,advantage of a turbine is to big.Twin turbo is to avoid turbo lag and get low rpm torque.

Answer 9

because they can.
dont question BMW.

higher powers resort to such.

Answer 10

really i dont know the answer
