Give the cheap stuff a miss for a while innit.

Most cars over here run just fine on commonly available E85, which is 15% corn vodka. :lol: Stoopid Yurpeen cars. :P
Stupid Americans. That have 3.5l v8s that pull about as much power as a Hybrid!
Right. I guess either youre drunk, or its just another random Bash America day. FWIW, American modern V8s get better fuel economy than their German counterparts. A new Chevy Impala gets about 30mpg on the freeway. Thats tremendous for a very large sedan with a V8, much better than the BMW equivalent. Would I rather have the Chevy then? Hell no. :lol: Just pointing out stupid baseless American bashing comments when I see them.

yeah, and the 3.4 puts down a
Massive 180Bhp, less than you get from a 2.0 Gold GTi. they got the fuel economy by wasting the power. The 5.3 will prolly be something stupid as well :\
thats probably because mpg is proportional to power produced
Quote from: Eddthats probably because mpg is proportional to power produced
not completly, efficiency is important.
you can get higher powered engines with better mpg than other equivelents.
306 d turbo - 1.9td ,90bhp, 45mpg
megane dti - 1.9td, 100bhp, 55bhp
200 sdi - 2.0td, 105bhp, 50mpg
Impala SS: 5.3L 303hp ~30mpg

Its rated about the same mpg as the standard VW Jetta we get stateside.
I wouldnt buy one, as the stylings a bit nasty, but Id rent one in a heartbeat.
better than i was expecting but still
BMW 335 - 2979 cc - 301bhp - 29 british mpg (about 35 american mpg)
isnt the 335 a tubby tho? kinda like comparing lego to duplo there
Quote from: Eddisnt the 335 a tubby tho? kinda like comparing lego to duplo there
yeah true, ok the audi a6 with a 4.2 litre v8 with 340bhp and 27mpg.
hmm would i rather a european car or a yank tank.. i think the choice is easy

Buy Volvo: best of both worlds :lol:
id like to point out that american freeways move slower than euopean motorways. in fact the limit is similar to the commnly ackowledged most economical speed of 56mph. and you still get less fuel economy and less power.
and yes, were bashing american v8s, because theyre slow, inefficient and old technology. is there anything american you wont fight for even though the rest of the world knows your wrong?
Matt
how does that come into an mpg conversation.
good one.
MPG ???? ;) I think it is nicer to know how much fuel it takes to drive one mile. My car takes .68 liters to go 10 kilometers :)
Quote from: redhow does that come into an mpg conversation.
good one.
americans are doing 55 on the freeway when they are calculating their mpg.
europeans are doing more like 70 when calculatin their mpg.
its fact that the faster you are going, the more drag you get, the more fuel you use, the less economy, etc etc blah blah.
Matt
yeah but your dig about fighting for something you know is wrong.
tbh im not desputing that as the airs viscosity has more of an impact at higher speeds. thats why teh veyron needs 1001 bhp to get up to 250 mph+ speeds.
Quote from: bytejunkieits fact that the faster you are going, the more drag you get, the more fuel you use, the less economy, etc etc blah blah.
Matt
No its not a simple as that.
Sure if you are going at 90 or something silly you will burn of fuel at a quicker rate, thats simple becuase of the higher revs you constantly have your engine at (depending on you car / gearing ratios.).
Your car will be most efficent at a constant 60-70 MPH. Its how hard your engine is working and how long it is staying at a constant speed, rather than stop start 30 mph town driving is the most inefficent way of your engine using fuel.
Air resistance has only part to do with it, the engine has to work harder to get up to that speed regardless of resistance forces in the first place.
56mph is supposed to be the most economic speed, which is why the US ended up with 55mph speed limit.
I love it on the news where all parties involved from porduction to sale of petrol are acting like school kids going
"was not me, I didnt do it"

sounds criminally slow to me, id never get anywhere at that sort of speed

yeah its like they are making out the cars all broke down by coincidence

Thats what all the American motorists said when it was introduced. TBH I think they are all right! Their government eventually dropped it and they can go at up to 80 on the freeway IIRC 8)
/waits to be burned by maxi...

its not that bad, if i am doing long distances on the DC/Mway i just get to 60 and wack the cruise control on.
i get near 65mpg doing that, goes down to 50~ at 70
ah so thats why theres always 60or less mph on the inside lane and 110+mph on the outside and surprisingly 80 in the middle with patches of 60.. why can no one actually do the speed limit on the motorway?
Quote from: Cypherthe engine has to work harder to get up to that speed regardless of resistance forces in the first place.
why? if there are NO resistance forces, then the engine wont have to work to get to that speed. if we could eliminate all resistance forces, wed not need energy to create motion.
say what you mean cos that doesnt make any sense.
Quote from: Serious56mph is supposed to be the most economic speed, which is why the US ended up with 55mph speed limit.
all depends on the total drag coefficient of the car.
Quotewhy? if there are NO resistance forces, then the engine wont have to work to get to that speed. if we could eliminate all resistance forces, wed not need energy to create motion.

He means air resistance.
If there was no resistance the electric system would leak all the power away and if it did manage anything it would be to fall to bits. Sometimes the English language is just too loose.
Even without that issue a car engine suffers significantly greater stress as speed increases. It still has to shift mass and components have to change direction
I have no idea.
The faster youre going the more fuel you use. If anyone cares google "Drag coefficient" and "Cd". There are other factors but if youre that pedantic you probably already know.
American cars - who cares? Some of them are sweet tho.
MPG - if it bothers you then you probably cant afford the tax & ins. anyway.
Quote from: sdpMPG - if it bothers you then you probably cant afford the tax & ins. anyway.
If you do a lot of Motorway miles you want a car that gets good MPG :p My Dad has a 1.9TDi Laguna Estate and gets roughly 57-58mpg at 60mph in 6th.
Even at 100mph in 6th his revs are under 2.5k and getting 45ish mpg.

Morrisons and Tesco have pulled petrol from some south east guarages, seems they were supplied with unleaded fuel contaminated with silicon.
