How VW's CO2 results compare to other manufacturers

[FaisalJ]

This arrived in my email just now, thought it was very interesting!

I subscribed to emails from "Emissions Analytics" after I bought some VW shares after the scandal broke. This just concerns CO2 emissions, but shows VW are far from being the only manufacturer with worse real-world emissions than tests.

so they're pretty much all at it ... comforting

Didn't we all expect that?!

Diesel is filthy! Though I guess that plots diesel and petrol. What we need to see is NOx.

Bizarrely... the graph looks like a Jag emblem....

Its a shame VW took the hit for this, especially as VWAudi make the best and most reliable cars on the planet.

Quality and reliability is far more desirable than how green its engine is.

Haha yes ! Nice spot

Agree

Quality and reliability is far more desirable than how green its engine is.

Wholeheartedly disagree.

LOL !!

I agree that engines ultimately need to become cleaner and cleaner as far as technology and usefulness permits...... but in terms of what road vehicles emit now compared to 25 years ago, we all drive cars that are a million miles away from what was running back then.... or indeed since the birth of the internal combustion engine (which is less than a needle scratch on the history of our existence on the planet).
I used to work for a company building the largest diesel engines in the world, and the largest we made would burn 2.5 litres of heavy oil per cylinder per minute.... and they were considered the most economical in the market for the power they produced.

Despite the endless quest for clean burning engines and reductions in harmful emissions, this planet has never ever been cleaner..... we are so far away from the dark days of steam and the colossal burning of coal for industry.
All of that is controllable with available scrubbing equipment available in todays technology.

VWAudi have literally been anally intruded for falsifying figures that other manufacturers have been equally guilty of also...... but this could very likely doom VWAudi.
They still build a bloody reliable, quality and eco-friendly product however..... no matter what is said.

The only true clean burning technology is hydrogen fuel cell technology...... and its odds on that the oil companies will stifle that being fully developed for as long as possible.....

I think it has taken a long time, but consumers actually wanting an eco-friendly car is becoming more and more mainstream. I think the arrival of Tesla has a fair bit to do with that, and the fact that there are finally now some non-<beep> EVs out there. It'll be interesting when their low cost model 3 arrives, looks pretty decent:

Aside from wanting one, you need to be able to afford one. Part of the desirability for one of these cars is down to running costs. Not just in terms of fuel, but an electric car has hardly any moving parts compared to a normal car (tesla s has 18 moving parts, vs 2000+ for internal combustion). The big issues have been battery life and cost, but battery tech seems to be improving too. With battery tech getting better, they get cheaper, which means the initial premium you pay for an EV is coming down rapidly. With oil prices as low as they are though, and not seen to be rising far anytime soon, I wonder how that will impact things.

Anyway, bit of a tangent, but I'm a Tesla shareholder too haha.

Back on VW, I really think they're the tip of the iceberg and the whole industry is going to come under a lot more scrutiny soon. VW, for their part, are handling this pretty well in my opinion.



What I would love to see one day, perhaps in the B12 RS4:

- Hybrid V8/electric combo
- Can run in full electric, hybrid, 4 cylinder or 8 cylinder petrol only modes
- Tricky one: An automated manual box. Effectively a fully manual box with clutch pedal, but then you can switch to a full auto mode.

The problem with battery tech is that it requires earth rapage not that far removed from oil extraction with the added issue that many of the metals are only found in certain places and then have to be transported half way around the world.

I cannot see battery tech ever making it really big. It will be overtaken by H-Cell.

I'd like B12 to come with decent customer service!

Thread resurrection time...thought this was quite interesting.

Further proof today (from the Government this time) that it's not just VW diesels that are highly polluting. The interesting bit of this for me, was about the exhaust gas recirculation technology; how temperature sensitive it is. Works well with a cold engine, as per the current lab testing, but not when the engine is warm.

The tests involved lab and track emission testing, with "cold" and "hot" variations (hot = warmed up engine). When tested "hot", and in the real world, several cars suddenly look a lot more polluting than they did from startup in a lab!

Even in the lab, if the engine is allowed to warmup then tested:

Then comparing warmed up engine in the lab vs. on the road:
