fuel economy and emissions

What mileage per gallon would I get from a Mercedes-Benz E-Class 1.8-litre petrol automatic? Also, how much road tax would I have to pay?

Thank you

How many miles to the gallon will the 2008 Toyota Prius do?

We have a Hyundai i30 1.6 CRDi. How far can we go on a quarter tank?

Is it possible to disconnect the stop-start function on my 2012 Volkswagen Golf BlueMotion? I keep forgetting to switch it off until it cuts out the first time I stop. Surely it must eventually wear out the starter? It drives me crazy - makes me look like I'm letting the car cut out all the time. If all vehicles had it the streets would be polluted with the noise of dozens of car engines stopping and starting. I'm not convinced that this particular innovation will be popular. What do you think?

What is the correct average mpg of the 2007 Lexus IS 220d?

I have a Volkswagen Passat BlueMotion with just 4,000 miles on the clock. The fuel consumption is increasing and has gone from 53mpg average in October to 48mpg now. Dealer says he can find no fault on electronic test rig. Any ideas please? Previously got over 60mpg on same journey now getting 48-49mpg and seeming to be dropping. Variables like fuel etc. all same as is possible and driving style not changed. Best regards and Happy New Year to all.

What is the fuel consumption of the 2004 Opel Meriva 1.6?

Do you know the combined mpg figure for the new 2012 F30 BMW 316d sedan?

What is the combined fuel economy of the Toyota Corolla?

Hi guys,

My question has two parts. Firstly I am changing car and always drove a diesel but am wondering about improved economy of modern petrol engines, e.g. VW Jetta 1.4 TSI vs.  VW Jetta TDI. Maybe you can advise what criteria I should consider?

Also, as my mileage is difficult to predict, I am concerned that if I am not doing enough miles I will have problems with the particulate filter on a diesel. What do you think?
