Hardly a surprise. The Honda and Hyundai false MPG lawsuits may have taught BMW something. But the real surprise comes when people are buying BMW for MPG...

Those numbers are not too shabby either.

BMW is actively working on performance and high efficiency strategies. So the surprise is a well performing F30 that gets decent gas mileage.

Some of my BMW owning friends have gone to performance school and they still drive like granny, but are very capable drivers.

I don't understand you single out BMW owners. I know many people who own "performance" cars that don't know even how to change a flat tire, let alone horse power and torque. Last I checked knowing hp/torque or whatever, is not a prerequisite to buying a car.

As I keep saying, BMW delivers the goods. When people buy a BMW there is an expectation of a certain level of vehicle. However, you seem to have a circle of friends who you believe are incompentent *****. Maybe they know something beyond the specs.

Yup, right on the mark of a thirsty 4 banger.

Yup, just don't forget to duct tape that turbo.

HAHAHAHAHA! Good one!

I am not a fan of a Turbo from a reliability and longevity standpoint. I know improvements have been made - but those things generate some heat! Has anyone cured oil coking in those things? I know it can be minimized...you can simply take a slow victory lap around the development before going home...that would help

My Subaru turbo has been flawless. As long as you follow the manufacturers recommendations, the turbo should last and last in a modern car.

33 is a thirsty four banger?

MalbecG37S

Well - I'm not saying it's thirsty - but the 3.6ltr 6cyl in a much larger Chrysler 300 is rated at 31mpg highway.

Even the 305hp 3.7ltr in the Mustang is rated at 31 highway.

Hey wait - wasn't the 2012 335 rated at 33 highway?? What the .....

Anyways...as always, your mileage will vary!

Edit: just checked BMW's own web site. Both their 328 and 335 are rated at 33 highway. Strange...240hp vs 300hp. Both get the same highway mileage rating. Don't you think they would have done something to the 4cyl to eek out at least ONE more mpg? Oh well...as I said...YMWV

Didn't get it? A quick compilation gives below list. (city/combine/highway)

Toyota Camry 2.5 L, 4 cyl, Automatic 6-spd 25/28/35
Nissan Altima 2.5 L, 4 cyl, Automatic CVT 23/27/32
Honda Accord 2.4 L, 4 cyl, Automatic 5-spd 23/27/34
Hyundai Sonata 2.4 L, 4 cyl, Automatic 6-spd 24/28/35
Mazda 3 2.0 L, 4 cyl, Automatic 5-spd 24/27/33
Toyota Corolla 1.8 L, 4 cyl, Automatic 4-spd 26/29/34
Honda Civic 1.8 L, 4 cyl, Automatic 5-spd 28/32/39
BMW 328i 2.0 L, 4 cyl, Automatic 8-spd 23/26/33

The 328i beats no one in that group of popular 4 bangers, and none of other 4 bangers has 8-spd AT, engine start-stop, regeneratic brakes...gimmicks. Yea, yea, I know it gives when the turbo blows, so it goes the MPG. You have to drive like a grandma to get close to that number, so it goes the "ultimate driving machine".

MalbecG37S

From a technology standpoint - do you know what they changed to get them to last? What type of oil do they recommend? Is the turbo bearing cooled?

Just curious...that's all. I still prefer NA for long term reliability - but it's good to hear that much progress has been made on the FI side.

Thanks.

328 is also more of a performance vehicle with performance close to the g37. The BMW trend is for smaller, lighter more powerful engines. Americans still like their big old v8s. A smaller lighter engine allows for a more balanced car. Of which only one in the group maybe is.

The fact you are comparing liters and not suspension, tuning, etc is amusing. Might as well put the STI on the list also.

My Subie uses engine oil for the turbo, that's all I know. Occasionally I clean the inter cooler. It's very fast off the line and eats deep snow for breakfast. However no question, I like the g better.

Some of it is advancements in oil technology and the fact that most all new turbo cars require synthetic (VW/Audi is big on this). The other part is advanced materials that take to the heat better (ceramics) and many of them have a water cooling element coupled with the oil these days. Also, the use of better intercoolers and controlling the heat through tuning helps to keep the EGTs down and overall improve life. In a modern turbo car it's no longer necessary to wait for them to cool down, turbo timers are a thing of the past.

The turbo in the new 328i is pretty advanced, it's a twin scroll unit. Probably good for over 300whp on a tune, reliably.

It's normally not turbos themselves that create unreliability but a lot of the associated components such as the fueling and electronics. The thing I would be worried about is BMW doesn't really have a history of turbo cars, where as say Volvo, Subaru, VW/Audi, Mitsubishi etc. have been doing it for years and it's part of their core lineup. I guess only time will show how reliable the new BMW setup is.

That post was a response to your amusing question. Try to pick words out of context again? You sound more and more like a BMW sales person.
