Has this thread highlighted to anyone else how the MPG on bigger petrol engine cars is not actually that bad??

It's only on my mind as I've just hopped from a 1.9tdi VAG product to a 530i BMW this week. So I'd braced myself to get hit on running costs...

The A6 only got about 40-ish MPG (maybe more on some runs, but not a lot more). The 530i auto on the same run is returning about 30 MPG. Factor in the cost price difference at the pumps and all of a sudden, a larger petrol engined car is not that much more expensive for that 'nice' feeling when driving it.

Factor in cheaper purchase price and lower service bills, and it's not far from being the smart choice for the heart and the head.

2003 Civic Type R - in general use between 34 & 38mpg. If I'm really trying, over 40mpg. If I'm really not trying mid twenties. or should that be the other way around?

Economy fact - a friend participates in competetive economy runs. On these runs the cars often return up to 20% more than manufacturer's quoted economy figures. Stands to reason, they're being driven by people who know how to drive economically. Recent tests have seen hybrid cars included (Prius & Civic) which have so far failed to even match the manufacturer's quoted figures scratchchin

Never driven a Honda Insight then? I can comfortably exceed the manufacturer's stated figures in one.

On long runs no hybrid is going to be any good, your using the petrol engine ALL The time and lugging that huge weight of motor/batteries around. Hybrids ONLY make sence if you live in London of similar cities and spend long times sat in traffic and when crawling doesnt mean bring up the revs and creaping but just letting the motor drag you forward and only using the petrol engine to charge the batteries or for opening it up on faster roads. Many tests have been done with hybrids and they ARE good in the RIGHT situations for which they were designed... long motorway economy cruising is NOT one. If you want good MPG on long cruises, a BIG engine that wafts along with little more than Idle is almost the best way unless your on your own like i am for commuting in which case a little micro-hatchback makes sence. For most people who do decent mileage hybrids are a waste of time yet people still buy them without doing their research and use them incorrectly!

So how come a Honda Insight can return 100mpg on the motorway (and yes, I've seen over 100mpg average on a tank of fuel in one)?

The modern hybrids are just marketing exercises. If I was buying a car for lots of motorway miles, I'd be buying a small diesel.

ETA: By the way the answer is nothing to do with it being a hybrid per se, but that's not the point.

BMW 130i 2007
Average around 35mpg on my 16 mile (each way) commute of fairly free flowing A-roads. This has improved significantly in the last couple of thousand miles (6k on the clock now)

If you dont live ina big city why would you buy a hybrid ? a hybrid has to be driven quite slow to get the mpg you was told at the dealers ( thats why you find all the hybrids in the slow lane ) and why ppl knock the hybrids ? Is it because we are all here petrol heads ?
You will find that for an average family in a big town the hybrid does save a bit of money even more if you have to pay for the congestion charge !!
I once drove about 2 miles on electric only ( you have no ideea how good that felt )

2002 Mondeo tdci 130.

Worst - 35 mpg on a summer mtb trip - 3 up, plus luggage, plus DH bikes on the tow bar. Average speed just shy of 80mph for whole trip... including Alpine passes.

Typical - 47 - 50 mpg on motorway / 44 - 47 urban (not crawling everywhere, but some stop-start).

Anyone ever been amused by their track day fuel consumption? It's vaguely entertaining trying to see how low it will go!biggrin

We get an average of 57 mpg on our Polo '02 1.9 tdi sport 100. Thats regular commuting through a 30 zone for 1 mile with traffic lights then DC (75 leptons) for 10 miles then 30 zone for 1 mile. Some occaisional trips on the M4 also at 75 leptons. It's like a little economical tank!

Have not worked out the Euno as I do very little miles in it. Would estaimate it at being 30mpg.

'05 Mazda RX-8 230 - 18 mpg mixed driving.

Never managed better than 22 mpg for a tank.
Same model and year, overall average 19.3mpg over 19524 miles. Worst 9.1mpg (track) 14.0 (road), best 30.1 (all motorway). Always get > 22mpg on a journey of any distance, but most of my driving is local rural roads.

Elise S1, ported head ITG filter BBR exhaust, tubular manifold, 39-42mpg 80 miles commute a day, 20 miles B road rest motorway or dual carriage way. (Bedford autodrome 12mpg!)

MG ZT260 Accufsab throttle body, Power shot air filter same journey 21-22.5mpg

All done by brimming the tank, resetting the odo and measuring the fuel put in at the next refill and caculating mpg from distance and fuel used (not using lying sorry optimistic trip computeer MPG estimates!)

I had a 2002 Civic Type-R, and I averaged 29.3mpg. Fuel consumption of VTEC engines is very sensitive to driving style; if you drive them gently they are very economical, if you're lead-footed they guzzle with the best of them.
