New LDV Fleet in UK Shows 2.8% Drop in CO2 in Q1 2008

| Sales-weighted average CO2 emissions per vehicle by manufacturer for new cars sold in the UK in Q1 2008. Red line shows the EU 2012 target of 130 g/km. Click to enlarge. |
The sales-weighted average CO2 emissions for new light duty vehicles (LDV) sold in the UK during the first quarter of 2008 dropped 2.79% to 161.13 g CO2/km, down from 165.76 g CO2/km in the first quarter of 2007, according to figures compiled by Clean Green Cars. Between Q1 2006 and Q1 2007, the average from new vehicles had shown a 1.23% decrease. However, since the EU target is 130 g/km by 2012, the rate of decrease will have to reach 5.3% per year to meet the target.
The data shows a wide variation between the performances of individual manufacturers; some have made improvements of more than 10% and some have made no improvements. Reflecting the progress made by parent BMW, Mini is now the lowest CO2 manufacturer on a sales-weighted basis in the UK, followed by Fiat, Peugeot, Citroën and Toyota.
At a model level, four of the five most improved models came from the BMW Group. The other model was from Mazda, which managed to significantly reduce the weight of the Mazda 2, thereby delivering an improvement in fuel consumption.
Clean Green Cars holds both CO2 data and registration data for all cars sold in the UK. The group has prepared three tables for the first quarter of 2008 versus the first quarter of 2007:
Sales-weighted CO2 performance by segment;
Sales weighted CO2 performance by manufacturer; and
Sales weighted CO2 performance by model.
| Ten Lowest CO2 Models in the UK | |||

It is a great website, particularly if you are European and know the cars.
The results show the effect that the EU's 130gm limit is having on cars being sold in Europe.
BMW were very quick off the mark, but you can expect to see the rest moving as they refresh their model ranges.
It is interesting to see how little the small car manufacturers have improved, presumably because they were fairly efficient to start with, and do not have a lot of money (/vehicle) to play with.

There is a relation between displacement, mileage and CO2 emissions. As more car companies are trying to get better mileage, they may reduce displacement and CO2 at the same time.
I was reading about the MIT ethanol injection method. They were saying you could get 150 hp from a 1 liter engine and 30% better mileage. If this is the future sign me up. I would love a 1 liter 4 cylinder turbo ethanol injected engine in my series/parallel PHEV.
The idea that I may have to go down and buy a case of ethanol bottles that I plug in every fill up does not bother me. Eventually, the fuel stations may provide E95 wet ethanol at $2 per gallon. That would be just fine. A small engine with lots of punch and fuel savings too...nice.

sjc: Whatfor do you need 150 hp (110 kW) continous power in a PHEV? Driving bricks (Hummer) uphill the Himalaya all time?
The thing is, we'd need *MUCH* smaller engines with only ~20-50 kW contious output at peak efficiency - all the peak driving loads can be covered by the battery in a PHEV, thus you only need the average (highway) load rating for the engine...

The point was that you can get high output from a small displacement engine. If you look at the trends in car designs, you will notice more horsepower. I think people want power, acceleration and economy all at the same time.
If the car is running in parallel hybrid mode on the highway and the driver wants to accelerate from 50-80 mph to pass trucks on an incline, it would be really nice to have the power on tap. This is what sells and the company that brings it to market will probably succeed in making more sales than the company that wants everyone to change their ways to suit the product that they offer.

It's impressive and depressing at the same time that the Prius is the vehicle with the lowest CO2 emissions.
Impressive that a 5 year old car is still at the top.
Depressing that no one has been able to beat it after 5 years.

"It's impressive and depressing at the same time that the Prius is the vehicle with the lowest CO2 emissions."
actually it isn't. the VW Polo Bluemotion gets 99g/km and the smart fortwo diesel, when it is released, will get 88g/km.
"people want power, acceleration and economy all at the same time."
this can be done, but not if we insist on making 3-tonne monsters like the Porsche Cayenne. these flying bricks should be banned.

I do not know how far you would get with that ban. I suggested that pickup trucks in the U.S. be sold only to people that had a legitimate commercial use for them. That proposal caused an outrage on this Green Car site. It seems that even among environmental innovators, there is a limit to what will be tolerated.
