bimmer engineering?

Seems as many of the mag racing times I've seen for bimmers seem quite quick for the power/weight ratio they output.

But what are some realistic 1/4 manual times YOU people experienced at the track with your 323 manuals, and 330 manuals?

I also heard BMW's auto tranny were from GM?
Anyone have any websites? Or can vouch on that?

Also, how do you see the reliablity of the fine BMW's?

Say compared to toyota and honda?

True.

The GM 5L40-E transmission is used in these 5-speed RWD vehicles:

BMW 3-Series
BMW 3-Series Sedan and Wagon
BMW 3-Series All Wheel Drive
BMW 5-Series
BMW X5 Sport Utility
BMW Z3 Roadster
Cadillac CTS
OPEL Omega
ROVER Range Rover


This is the gearing ratio used:
First: 3.42
Second: 2.21
Third: 1.60
Fourth: 1.00
Fifth: 0.75
Reverse: 3.02

GM makes a decent auto tranny.. but really if your in the market for an automatic why buy a bmw?? but if an auto car is what your looking for.. maybe a trip to mercedes would be in order.

And no. BMW are not as reliable as toyota or honda.. just gotta deal with the repair bills.. and why not, it should cost money to drive a german luxury car.

sorry you were asking about the 4-speed hydra-matic tranny's.. again, also GM tranny's... not sure about exact specs though.

Same auto tranny's that are in Isuzu, Rolls Royce, and military vehicles.

...

well I never knew GM and reliable we're in the same sentence!
I had a malibu before, never knew the tranny in that car is actually known for the bimmer boys, buy now I am informed.

anyways, I was inquiring it more for a friend... I have a Nissan actually.

he and I believe that BMW uses better nicer more high quality parts to make the overall car more elegant...

but I told him that quality also does not come with the reliablity...
I can't really explain it, but in a way I also think, if its better quality, why isn't the reliablity accompanied with it?

I also believe you get what you pay for, since german cars are the most elegant, and you pay quite a bit for parts. Shouldn't the elegance & reliablity come in 1, because in a way I feel it ain't worth just the elegance for that price, WITHout the reliablity.... ???

not to mention insurance and parts, etc

Well when you mean COST more, I rather it COST more as in, it has the elegance AND reliablity.... NOT just elegant, and taking it to the shop "often".... and the repair bills COST more...

american cars = not reliable/nor elegant, BUT cheap
jap cars = reliable/moderate elegance, ok price
german cars= soso reliable/extremely elegant, BUT pricey

so which car is = extremely reliable and extremely elegant, but pricey, than???

GM is known for their tranny's.. also used in Rolls Royce and Bentley's.

GM cars still have some issues.. Pontiac is getting much better though. However, their tranny's are up there... some of the best in the business.

BMW reliability I'd put on par with Japanese cars. American cars being much lower. Which really isn't that bad when you look at the complexity of BMW vehicles / electrical systems / etc. compared to many of these other vehicles.

bottom line though.. no matter what the car, if you want it to last, you have to maintain it.

the only thing i can mabe see doing that is a porsche.. all the extreamly elegant and posh cars require more servicing then BMW.

The parts bmw uses are good quality and they fit and function like no others.. but they come at a price and the typical parts like breaks, bushings, window switches and spark plugs don't last any longer.

here is a cold hard truth for you.. my Toyota, made in 1983 started every single day in the ice cold winter, never ever let me down, hit every gear. I beat the piss out of it in -15 degree weather next to no motor oil. My bmw parks if it rains and parks all winter.. why? cause it can't take the abuse! and i don't wanna dish it. but in the end what do you wanna drive? hahha

Well Nissan is inferior. But my issue was GM tranny and the reliablity. He also thinks his 323 stick with moderate driving skills would demolish an auto v6 250hp 2005 altima....

You sure it's a GM tranny? I always thought the 5 speed non-overdrive ones (5th gear is 1:1 ratio) were ZF trannys...

BM reliability is on par with Toyota reliability as long as you take care of it. If you abuse a BM, it'd eventually break down. A Toyota can take more abuse before it suffers the same fate. Some cars, like DaimerChrysler products, will suddenly stop functioning even with regular maintenance and woman driving.
