fuel economy

Post by **special** » 10 Oct 2004 10:32 pm

is there any difference in fuel economy between the carb and injection models on the 360
or is the 1.7 the better of all three models

Based on official figures, 1.7 is more economic than B200 and B200 carb is more economic than B200 inj.

Oh! The results for the B19 are strange... So much fuel? More than the B14?? Is it the B19A or E?

The B200K is a LOT more economical. Drive it at a constant 56mph on flat roads, and 500miles to a tank is achievable, as is well above 50mpg!

Having owned a B14 4spd and a B19A 5spd and with my parents owning (at the time) a B172 5spd I can say that the 1.7 is the most economical, with the 1.4 and 2.0 being about the same.

the figures would back this up. 1.4 is better around town than the 2l, but on the open roads its about equal. the 1.7 is best.

But you've got to contest with that carb-base warping problem

I ought to add that the B200K 360 is a tale of two halves. It has a huge range of MPG figures - a good example can and will return up to 55-60mpg on a full > empty 56mph run on the flat (if you can find a long enough stretch of flat road - I usually get to Exeter at about 400 miles, and have to climb a huge range of hills!).

However, short urban journeys from cold will see you returning 10-20 mpg. The way this thing drinks fuel when its cold in town just isn't funny! If you do more short journeys, get a B200E. If you do longer journeys, get a B200K. If you don't give a toss about economy, but want a fast car, get a GLT, and put a more powerful engine in it. None of the 360s are really that quick. Well, maybe they are compared to a B14 340.

Glad the B200E is better on shorter stints - I shouldn't really be buying a car like this as I do mainly town driving, with a bit of dual carriageway in between - oh well! Should be farily good on the motorway though.

It'll be interesting driving the 360, as to me they will probably be very fast compared to what I've driven before. Maybe you've just got used to the power?

Oh absolutely - compared to the Tigra I learned in it was a rocket ship, and the noise....Oh yeah! - Hit 3500rpm and it just growls at you! And of course its engine / induction roar, not ricer exhaust rumble. However, lets not forget that it was a 'quickish' car 20 years ago. That makes it very average today.

The nice thing about it is how it delivers the power, in that you can get a couple of car lengths on almost anything if you try hard enough, as the power comes in pretty low down (albeit at the expense of top-end power). I can easily take a Civic TypeR before it hits VTEC...then I'm in major trouble....

If you want a decent real-world comparison, a GLT is a little bit faster than a mk2 Golf GTI (8v). It's a pretty decent match for a 8v 2.0 Cavailer / Sierra. Don't forget that 300s are bigger than most people think. It's much closer to being Sierra sized that it is Escort sized.

The B200K (thanks to its lazy-as-hell cam and economy carb) is about as powerful as a modern 1.4 or 1.6. Having said that, it might share a peak BHP figure, but it delivers 90% of peak torque from 1500-5500. That, a 1.4 tuned for power will never do. *Peak* BHP is almost complete irrelevant in real-world driving - its all about bragging rights really.

Can't wait to drive one for myself - sounds like good fun, never heard a B200 running before though, so dont know what they sound like atall! Even the 1.4s we had were pretty good from a standstill, with nowhere near as much wheel spin as the front wheel drive cars I've experienced (with similar power) - the front wheels spinning really does annoy me sometimes when pulling out onto an island etc.

I don't know why but the 300 does look small, but then when you see it against other cars it is quite big!

Hehe I have it reverse. When you floor it nothing happens at first but when the boost hits in at ~3500-4000rpm comes the power peak.

Though with something more modern turbo, something else than old T03, the lag would be much more minimal. That's in GLT though it leaks between the turbo and exhaust manifold so that makes "some" lag also. In GL (which doesn't have any leaks

) the response for gas pedal is much better when you launch from still position. Should get that leak fixed during the fall.

Post by **foggyjames** » 13 Oct 2004 05:22 pm

Indeed - turbolag is a little more complex that this, but basically, the smaller the turbo, the less lag you'll have. That's why the 940 LPT (turbo spools at 1500rpm) has a TINY 13c turbo.

Steve...whereabout in Brum are you? If its anywhere I'll be passing shortly, I'll take you for a spin prior to your purchase

cheers

I do mainly town driving and the economy isnt great on my/your GLT. Its perks up a fair bit once you get out on the motorway though.

A word of warning though if you're not used to the GLT - be careful in the wet, it can be a bit twitchy at the rear end!! Decent tyres are the way forward though!

Post by **SteveP** » 13 Oct 2004 05:42 pm

So I've heard about the twitchyness... If I like the car after driving it a few miles and decide to keep it for a while, I might buy a set of late 440 alloys and decent tyres as they can look quite nice!

Think I need to be learning oversteer in a deserted area or something!
