BMW Intros 40 mpg+ 328d

How stricter are US emissions compared to EURO 5 or EURO 6? I thought that EURO 5 is very close to US standard, EURO 6 is definitely there, or not? Is test cycle for measuring that different and you just don't get the same numbers?

 

Prius £21,845 to £25,145 inc 20% vat/sales tax

BMW 316d Sportwagon £26,510 to £33,135
BMW 320d Sportwagon £29,710 to 35,990

The 3 series hybrid costs £40,500 over here!?!

Can't find anything regarding which emission level they comply with as I don't think Euro6 is officially here yet, but usually the premium brands like BMW and Mercedes build their cars to comply with the strictest international standard. I remember an old diesel Mercedes from over 10 years ago that was super clean on the inside of the tail pipe and didn't smoke, even though the standard then was Euro 3. I think they build some future compatibility into them.

If I understand correctly, doesn't the new Prius comply with Euro6 already?

Proactive manufacturers seem to be at the forefront of low emissions but ones like Renault seem to only just squeeze through. If I recall, there was one new Renault diesel that emitted 1,000 times more Nox than the Prius, yet was still legal!?!

(Euro6 is for petrol and Euro VI for diesel if we're gonna be really picky)

 

Looking at EURO emissions standards for petrol 5 and 6 have the same values. EURO 6 for diesels has more strict NOx standards, PM are at the same level as EURO 5.

For US generally speaking all new cars should be at lest LEV II (Low Emission Vehicle) by CARB, these are the values that will last till 2014:

NMOG: 0.090 g/mi
CO: 4.2 g/mi = 2.6 g/km (EURO 5: 0.5 g/km)
NOx: 0.07 g/mi = 0.044 g/km (EURO 5: 0.18 g/km)
Formaldehide: 18 g/mi
PM: 0.01 g/mi = 0.0062 g/km (EURO 5: 0.005 g/km)

As we can see the biggest problems for diesel car will be getting those NOx values. European version of this BMW gets 0.171 g/km NOx, the cleanest Mazda skyactiv diesel gets 0.068 g/km, the test procedure is not the same so comparing this values is difficult, but we can conclude that US version of all diesel cars need better NOx treatment than EU versions.

 

There is currently a version of the 320d in Europe that is certified Euro 6 -

darn. I should have waited for 328d instead!

 

Thanks,
The prius is much more expensive in England than the US, the 328d car will start here around 26,500 pounds ($40,000) before tax, the sportwagon price hasn't been estimated. Although the bimmer is not by any means cheap in England, it is a much better relative value.

The old Mercedes diesels here are a lot older than 10 years. The US went to much higher emissions standards and most diesels stopped being imported. Here is the new Euro 6, which is very close to EPA, meaning Manufactueres can build a similar car for the US and europe. It appears that this bmw has already made the transition from wxman's post. I thought perhaps the higher price was for better emissions control.

I'm sure it does, the atkinson engine and cooled egr provide very low pollution, meaning you could even cheap out on emissions control. Diesels are the opposite the exhaust is cleaned after the ice, perhaps with euro 6, this emissions technology will get cheap like catalytic converters.

 

yeah, except for all of the interior and exterior, you are correct... so you basically are not correct at all

 

BMW has no de-nox treatment in europe, so it will need to beefed up for US.

ah, i got it... i was just configuring 320d in UK to see "real" pricing compared to top Prius, since base BMW's dont get anything in them for base price... and I see they charge 995 GBP for Euro VI package they call "BluePerformance"... so basically Euro VI is optional and probably nobody gets it, and uses urea most likely.

otherwise if you spec top end prius and 320d similary, difference in price is around $20k.

 

I think there are some tax advantages to the lower emission models so it can make sense for someone to pay extra to get the newer emission levels earlier than when they're legally required.

A lot of the diesel cars on the road here do indeed use urea for Nox, and some have done for over 10 years. I remember the Peugeot 607 needing urea treatment back in 2002 when I nearly bought one.

yeah, usually when they call diesel blue-something it uses urea, thats what i meant.

EuroVI - BluePerformance - i never saw this tested or ever mentioned in any magazine, so i would guess probably not many got it, or maybe it is only factory option. 1.1.2014 Euro VI is mandatory so every diesel will have to have it.
