Trickle-down tech: Non-hybrid BMW 5 Series to feature regenerative braking
Using recaptured braking power to recharge batteries has been a staple of hybrid technology since their start. BMW, a company which has not released a hybrid model as of yet, plans to put into production a new type of alternator in their newest 5 series models which will recharge the battery in the car under braking. The system also includes a new type of lead-acid battery that can take the extra quick blast of electricity in stride.
BMW plans to improve the efficiency of all their cars shortly as part of their Efficient Dynamics Program. The program will focus on improving efficiency in areas such as aerodynamics, tire technology and engine stop/start features. Expect to see systems such as these and the regenerative braking on other BMW models shortly.

Even GM called their version of belt alternator starter (BAS) a hybrid, but not BMW! BMW has been badmouthing hybrids too long to admit they are a good idea, and couldn't make an efficient car if their survival depended on it. Their nature is to make gas guzzlers for the idle rich, and have no real concern for economy.
Their designed-to-fail "Hydrogen 7" is a perfect example - oversized and inefficient.

CM, BMW makes the new Mini which is rated at 40 highway mpg. Their 330d and 320d get 40 and 50 highway mpg, respectively. Oh, and their 335 coupe gets 29 mpg highway, while accelerating to 0-60 in the low 5 second range. Everyone knows they are constantly engineering improvements in emissions and weight reduction. Whether the experimental Hydrogen 7 fails or not, making a world-class luxury car with tailpipe emissions of water vapor is still commendable. Your jealousy is only surpassed by your ignorance.

Oops, forgot about the Mini.

Difference between diesel and regular gas engine:
I was deciding between a ML320 CDI and a BMW 535XI touring since I needed space for the family activities and wanted great fuel economy (I own a XC90 T6 from volvo which is a real gas guzzler). I almost went for the ML since the price was lower and fuel economy was great. After looking at the EPA numbers I changed my mind since their rating of this diesel engine was fairly poor (not the full bluetech yet. I believe I made the right decision but i don't know if anyone has a better take on it.
thanks
