Green 3 series

taken from Autocar

Green engine technology that can improve fuel economy and carbon dioxide emissions by over 15 per cent is coming to Britain’s favourite sports saloon, the BMW 3-series, this autumn.

All the four-cylinder diesel and petrol engines sold by BMW are due to be fitted with BMW’s ‘Efficient Dynamics’ technology, a suite of engine add-ons and equipment upgrades that some car-makers refer to as ‘mild hybrids’.

Four of the ‘Efficient Dynamics’ technologies — an integrated starter motor/alternator, computerised alternator control, auto stop/start and electronic power steering — have had stunning effects on BMW’s 1.8-litre diesel, just launched in the new 118d.

If the 15 per cent cut in CO2 and 16 per cent reduction in fuel economy in the 1-series are carried over to the 320d, it will rate 57mpg in the combined cycle (up from 50mpg) and just 132g/km of CO2.


Does anyone have any info about this?

I thought the stop start thing was already being rolled out on the 320D coupes?

The auto engine shut off is in the new 3 door 1 series initially and it will be rolled out accross the entire range.

They are also introducing regenerative braking - which essentially charges the battery when braking then cuts if the alternator to improve economy when accelerating.

Good news as I'm thinking of a six cylinder and ordering this side of September.

Because they are too stupid to know it's a 2.0. Then again, I can see why the uneducated would assume that, but you would have thought they would do some research before going to print
