What V8 has a respectable MPG?

You should have seen him on the Grand Cherokee SRT8 thread a few months back...

If I couldn't move for Grand Cherokee SRT8s, then I would accept I was wrong. Fact is, there is a reason no-one buys them in this country.

The LS430 I understand will knock out 30-33mpg.

A purely academic question. I was just reading the road test on the SLK55 AMG and the low CO2 and MPG surprised me at 195g and 33.6MPG respectively.

So what V8 (petrol!!) cars are out there that achieve a decent/respectable MPG (I don't care about CO2) that wouldn't make you wince when you visit a petrol station?

I think the target should be around the 30mpg. 20 is too low for my pockets!

30mpg doing what though?

Driving an enthusiastic car like a 2.0 litre Civic Type R how you are meant to and you'll struggle to better or even reach 30mpg. In fact on Fifth Gear last week road driving in the CRV Type R hybrid Vicky was only getting 29mpg from it.

I honestly don't think you'll find a single high performance car capable of a true average 30mpg under normal everyday conditions, unless it's a featherweight or a diesel.

That said, there are plenty of V8's capable of 22-26mpg as a real world average with the ability to attain or exceed 30mpg on the motorway.

Unless you only ever drive on the highway at a constant speed and a warm engine, it will NEVER achieve 30mpg. The city figure is 20mpg. That should tell you all you need to know. It will NOT meet the OPs criteria in a million years.

I would love to be wrong, I would love to be able to have a big engine that sipped at fuel, but they don't exist. Sorry if that is news to you.

30 mpg is actually very good, as is 20 mpg for a V8- end of story.
You wouldn't 'LOVE' to have a big engine, watching you driveling on and foaming at the mouth about electric vehicles. You'll only be happy when everyone is forced (via legislation) to drive around in electrical appliances so that they can 'do their part' in a meaningless farce. Why else would you welcome higher gas prices?

To get the roads to myself. The sooner morons like you who consider sub-30mpg to be acceptable are priced off of it, the more fun I can have.

30mpg average? Not going to happen, even in that SLK, or if you do you'd be driving so gently that an SLK 200 would have done the job just as well.

My LS1 equipped Monaro would brush 30mpg on the motorway but my overall average was around 17mpg. I think my mate's E90 M3 gets around 14.

ETA. My current Octavia vRS (2.0 turbo petrol), while not in the same league as 300bhp+ V8 cars is pretty quick and I get a genuine 30mph average out of that, often hitting high 40s on the motorway.

Your argument is flaweed, I left that festering socialist Gulag of an Island years ago. So don't let that stop you from 'having your fun' with your electric motors and Sinclair C5s

[MagicalTrevor]

Oops, this was meant to be a 'fun' thread! My 30mpg was merely a 'target' based on what MB were quoting.

I suppose the target figure was to be achieved with steady 60-70mph cruising on the motorway and is pretty immaterial really with a loud pedal sounding soooo lovely

A 6.2 litre Corvette will give you 32.5 mpg highway / 20 city and is exempt from gas-guzzler taxes.

That's dreadful.

is it? what else has 615bhp and is significantly better?

http://www.chevrolet.co.uk/cars/corvette/corvette-...

331g/km combined

The question was not how much power it has, but what economy it has, and the economy is indeed dreadful.

You sir are indeed a complete tool if that is what you truly think. Part of me hopes you are fishing troll, at least that way there would be some form of reasoning behind such obviousl ridiculous comments.

It's not brilliant but it's far from dreadful. Dreadful would be my old man's G55 which I recently managed to squeeze the heady heights of 14mpg out of on a steady motorway run, but usually sits at 11mpg. And that's the OBC readout.

Sorry, what is incorrect about what I said? The OP asked if there was any V8 that has a respectable mpg. It's a reasonable question to ask, because I'm racking my brains and I can't think of any.

Saying "20mpg is good because it has 600bhp" is not answering the question. It's totally missing the point.

And the American-centric posters like Marquis Rex and 5USA live in a dreamland where 30mpg is considered a thing of wonder.

So I ask again, what have I said that is incorrect?

What a stupid take on it quite frankly. Do you have any concept what the word "perspective" means?

I'm sorry I have to treat Marquis Rex like this, he loves it though. There's no point trying to reason wit him, because he is unhinged, hence my deliberately perverse post aimed at him.

However, I consider you to be a reasonable person. I've had some good exchanges with you in the past. The question the OP asked was: "What V8 has a respectable MPG?"

The answer, as you and I both know is "none". Just be honest with yourself. There's nothing wrong with that. The OP doesn't want caveats like "It has great economy... for a V8".

His posting history suggests he is primarily here to talk about bikes, with or without engines. It is a little odd that he finds a 60mpg motorbike transporting one to be entirely acceptable, but a 30mpg car transporting four abhorent, but such is the hypocritical nature of many PHers these days.

Well there seems to be a lot of people spouting sh!t and speculating quite a bit, so i'll throw you in some real world data.

Background:
www.fuelly.com is a website in which users update their mileage and fuel used every fillup. I myself use it, and it works well.
the data submitted is not manufacturers pipe dreams, and there is no incentive for people to lie on there, as it would just mess up your next data input.

Below is the report of Corvette v8s from all years:

So, in other words, you have no actual argument to offer against me, you just don't like what I am saying...

honestly, shut up, contribute, or f-off

[varsas]

I was quite surprised when my Stag returned 25mpg on a long run, not really taking it that easy.

Is that they are V8's or is it that V8's tend to have a large capacity and are attached to heavy cars with auto transmissions? I'd love to try a 2 litre V8 in a nice light sports car.

I wonder what a manual E34 530 (if such a thing exists) would return? 30+ if driven with care?

There's NOTHING reasonable about what you say here at all. If you were reasonable you'd realise that. The original poster asked for a reasonable fuel economy V8 and then laid down some rough guidelines. you then interject because it doesn't meet your own ridiculous guidelines. That's about as reasonable as saying electric cars are cost effective and better for the environment while convenienmtly ignoring how the energy got to the plug or the fact that the battery packs are heavily subsidised in the USA to give them an economic advantage.
