Just managed another, very very near, 400miles to a tank! :-P :loser: which is about 43mpg, 300miles is 34mpg. i think i may have the one car which does what the manual suggests! i'm genuinely impressed! if you don't believe me, i'm doing a trip to france from somerset the 15th, i'll post the photos of the dash including clock and the odd mileage sign to show it's genuine :-) the car has no modifications but was doing motorway miles at just below 70mph.

Okay, I am impressed! We only managed 250 on a tankful on our 300. You must be driving at 66.000 mph on motorways for 300 miles at a stretch.

if we ever do get our 340 delivered,( been waiting about 8 week's up to now)
we will see how much we can squeeze out of it our old 340 1.4 5speed we used to ge about 47 mpg on a long run and it was'nt too bad just running around town, so if it ever does turn up which we are begining to doubt very much i will see if i can beat it could anyone tell me as it is an auto will it make a difference on mpg because on our v70 auto it dosen't seem to make any between manual and auto.

Maybe my memory is playing tricks...it's been three years since I drove my 5-speed B14 340. I did calculate that it was getting 45-50mpg at 70mph, though, so I guess it must have been in the same mileage range...I just remembered it being lower, mileage-wise.

I always found mine to be excellent on fuel, as long as you didn't go past 70mph (much). Working B14s aren't as rare as (properly) working B200Ks, which are very nearly as good on fuel!

Edit: the varios are quite a bit more thirsty than the 5 speeds. 70-series autos are usually better than the manuals on the motorway, but quite a lot worse in town.

You must be joking, the B14 is good and I concur on the MPG for a good engine. But all the B200K/Es I've had had no hope of getting much over 30, except on a very long journey at say 50mph. Typically I averaged 28mpg in the B200K, compared to 45mpg in the B14.4 on the same journey (mostly motorway for 25miles each way to work).

Deadly serious....on the motorway, mine would do 45mpg at 70mph, and 50mpg at 60mph. Of course it was a different story in town, and the B14 was much better here, and an overall average of more like 30-35mpg was typical...but with sufficient discipline, my old 360 would pull some very impressive numbers out of the bag. Most cars seem far worse than this...I blame aged carbs!

GLTs, on the other hand, are nothing like as good (economy-wise, anyway). A combination of the short diff and usually knackered LE-Jet means they rarely top 30mpg. One with refurbished LE-Jet can do 35+mpg on the motorway, but that diff really counts against them (and was a stupid idea anyway, in my opinion...barely a performance advantage worth mentioning, and it makes them less refined at speed).

Haha i see i've prompted some memories here! I only get these kind of figures by doing long journeys without breaks with a very steady little toe! i managed 400 on the trip but forgot to take photos but i can promise you they are true! it won't get near 400 with daily driving to and from work but still extremely efficient for an old car, not many that are!!
I'll try to record it next time!

Don't argue with dis man. He's register keeper, he throw you off if you disrespect him.

Haha i'm not, i'm agreeing :-) These a truly superb vehicles! I did 600miles and three countries in one day :-D This is a good road trip vehicle. If you fold the rear seats down and slide the front forwards you can fit a double li-lo in the back!

We've had four. I can't recommend the 1.7, it felt under-engineered somehow. At 120,000 we had head gasket gone, shocks gone and intermittent lumpy idle and were glad to get shot of it. But the 1.4 we currently run - well for a 25 year old car it still tanks along. As you say, load space is fine except that ours has a big gas tank in the boot. Polishes up a treat. What more could you ask?
