Quick question sparky --->

Are you going to buy a new car simply for fuel efficiency or did you already have plans to buy a new car and just want a fuel efficient one?

I never mentioned anything about a new car. The Primera (new to me) has a trip computer. I've been playing with it. Recently worked out the Micra was giving me poor MPG and thought the Primera wouldn't be that much worse And it isn't.

I recently calculated that the vehicle with the greatest tank range, currently on sale in Britain, is the Peugeot 607 2.0 HDI 136 PS. Taking the extra urban figure (56.4mpg), and its tank capacity of 17.6 gallons, in theory it should do 992.6 miles to a tank.

Thats incredible. I wonder how realistic it is.

Interesting alright. But its so far removed from everyday driving you have to wonder how useful it is.

Well, I get around 60-65mpg around town. This will improve when the engine loosens up.

Well, my 1.9 CDTI Vectra has done over 625 miles on about 12 gallons of juice (over 52mpg

), driving to Glasgow and back, including longish periods of M6 with the cruise set to 80

, so that sort of consumption should be possible.

I've only got a 13.4 gallon tank though, so my range limit is somewhere about the 700 mile range.

On the same journey, my old 2-litre petrol Vectra would only just break 40mpg.

Round town is much more in the diesels favour though - 35mpg compared to 22-23 :eek:

From what i've heard the Audi A2 1.4 Diesel is pretty good on economy too

Always liked those A2's. Not many around, too pricey I guess.

Thats not bad. You probably would have done better if you'd keep the speed down. They reckon speeds over 60mph decrease fuel economy by 33%. Not that theres any fun in that. Rememeber Top Gear did some test like that, but they got incredibly bored with it.

I'm not so sure. 60mph is noticably below peak torque RPM in 6th in the Vectra (peak torque starts at 2k rpm/70mph), so you are not running so efficently, particularly when you come to hills and such like.

I think I could have got it up to 55mpg, but probably not much more

I think wind resistance is a factor aswell.

Dogbreath · 2 Feb 2006 at 00:25

Drag is a big factor, it rises with the square of the speed, which means the power required rises with the cube of the speed.

How about the '3 litre' VW Lupo.

That would do 100km on 3 litres of fuel.

Its a nice idea. Never seen one though. I remember a few years back VW had a MKII golf which would turn itself off and on when you were sitting at the lights. Can't find any info on it.
