New Astra 2010 Engine Improvements to MPG & CO2

Vauxhall have recently released the very sexy new Astra, definitely a big improvement looks wise on the old shape both inside and outside. But how much have the engines improved?

With fuel prices likely to go up (popular opinion seems to be that it will rise by 15p in 2010) in the future, fuel consumption is very important, and also for you eco conscious drivers how have CO2 emmissions changed?

On this page we have some manufacturer figures for you, kindly provided by Torque Astra, a community for Astra owners and lovers to keep up with news on the car as well as chat in a forum and comment on articles, a great way to let your opinion be heard on the new car!

Figures

In the tables below you can see all figures for all engines. Here are some interesting findings I noticed from the tables.

The 1.4l petrol (100PS) has improved from a combined fuel figure of 46.3MPG to 51.4MPG, over 10% improvement. And CO2 is down from 146 to 129, a 17% improvement.
The most impressive figures are in the range of automatics. The 2.0 diesel (was a 1.9CDTI) has gone from 40.9MPG up to 48.7MPG, that’s not far off a 20% improvement! The CO2 is also 17% better.
However, the 1.7l diesel (110PS) has gone from a combined fuel figure of 62.8MPG to 60.1MPG, this is very disappointing to see the MPG has actually got worse! The CO2 has improved by 6 G/KM though.

Here is a list of all the different engines and there figures so you can compare them all (click to enlarge). The first table is the new Astra, and the 2 tables below that are of the petrol and diesel engines for the old Mk5 car.
