Who needs a Prius?

Mike Duff

So after taking some flack about the alleged weight of my right foot – and the fact I can’t manage to get my Ford Mondeo 2.0-litre TDCI over 40mpg under everyday use – I nabbed a Mondeo Econetic that was sitting in the carpark for my journey home last night.

New Image Basically a slightly eco’d version of the 1.8 TDCI, the Econetic gets lower rolling resistance tyres, revised gearing and some aerodynamic tweaks to deliver a claimed combined mpg of 53.3 – compared to 50.4mpg for the standard 1.8 TDCI Zetec.

Anyway, to slash 50 percent out of a long story, I ended up mounting a one-man fuel economy run in the thing: aircon off, 70mph scrupulously observed and trying not to use the brakes unless strictly necessary, just to see what it was capable of delivering.

By happy coincidence I was sad enough to have done something similar in a boggo 1.8 TDCI last year, when I managed to record 53.9mpg according to the trip computer.

I thought that was impressive, but the Econetic knocked that into a cocked hat: see my slightly wobbly mobile phone pic for confirmation of a stonking 62.0mpg after 127 miles of motorway, B-road and urban sprawl. Granted, trip computers aren’t always completely accurate – although the one in my 2.0-litre Mondy is always close to the depressing reality.

For a car that weighs 1505kg – and which doesn’t get electric power steering, a part-time alternator or engine stop-start, breaking 60mpg is a remarkable achivement. And, for the record, it’s also 10mpg better than I’ve ever seen on the trip computer of a Prius.

Totaly agree with you, the Prius makes less sense everyday, especially as Bluemotion/Econetic etc. cars have better economy and emisions than hybrids. Also, one often forgoten factor is the ammount of energy required in producing these batterys, their short lifespan compared to internal combustion engines and the fact that disposal is nigh on impossible.

Can get our trip computer on 2.0TDCI titanium X (new shape, now 40,000!!) - to show range of 850 miles...if only that were true.

Rarely averages over 44 despite the daily commute being largely motorway miles. Must be the weight (of the car, not the right foot of course...!)

I'd be interested to find out what you get if you repeated the test with your 2.0 diesel, it would also be good to see what the Econetic returns if you used it everyday instead of the 2.0.

I get just over 40 mpg average from my manual S60 D5 185, which I find impressive given the fact that I enjoy using the considerable performance on a regular basis, . If I stop playing silly buggers and do a long motorway cruise at 70 mph, it's up to 50 mpg. As we enter the age of high fuel prices, it's good to know that I have the potential for excellent economy if I ever really need it.

Had the 'pleasure' of running a MINI Clubman diesel for 2 weeks after my BMW Dealer managed to prang my 06 120d whilst it was being serviced!!!

I did 935 miles in the car which consisted of motorway (approx 250m) 'A' roads (350m) 'B' roads (150m) and the remaining 180m in towns and even with its famed stop/start tech I averaged 56.5mpg and I didn't shoe it either given it wasn't my car. More so when I got it it was showing an average of 51.4mpg.

Interestingly my 120d with a lot more 'go', over a similar distance and usage, averages 48.7mpg and I do go a little nuts sometimes.  I reckon the new 120d ed would easily better the MINI and the Prius.

Joe - actually the energy consumed by producing batteries for hybrids is something a lot of people do go on about, but no-one ever backs up with any figures, just hand-waving.

NiMH and Li-Ion batteries are recyclable - though of the 30,000-odd tonnes of waste 'consumer' batteries (equivalent to 600,000 Prius' worth) generated in the UK each year less than 5% are currently recycled.

I had a Prius on hire for a week, and then the following week a 318d.  Doing similar mixed road journeys on the same roads in similar conditions.  The Prius couldn't get close to the 318 in terms of economy, and while the 318 was not exactly a peach of a car it beat the Prius in just about every measure you can think of in terms of car ownership...except for boot space, and if that were necessary, I'd go for the touring.

Niall, The greenies who drive and promote these cars do seem to be "blissfully ignorant" of this fact. Still, they never were up to date on global events.

Efficient Dynamics (God I hate that name) is the way forward.

Don't forget that when the Prius was launched, cars like the ECOnetic were only found in the automaker's nightmares.

Second, the Prius will be replaced by a much advanced 3rd generation next year, would be interesting seeing what it could do then.

I agree rtwingo.  with the funding going into this area the progress will hopefully be rapid.

also, whilst it's great that you can get such good performance if you have the aircon off, keep to the 70mph limit and stay light on the brakes, unless you're going to do this in all the experiments you try i'd like to know if you've done the exact thing in a Prius?

it might be 'scientifically' comparable then; rather than have a hint of trying to make a point.  

still, if so, well proven.

sotw, you are quite right. Driving in and out a city each day (74 mile round trip) lots of stop start on the M4 plus the inevitable city grind - an average over 20k has been 51mpg. Fantastic as a fair bit of the time away from this sees the DTC off! When living in Bristol was using an Aygo - could park in all but the bike SMART spaces, tonnes of character, 60+ mpg. Prius? Eh? Why?

Seriously - if you are in the dealership and you are their to stroke your green ego then you should walk out after signing for the Aygo or save a few quid and nip over to the Citroen/Peugeot dealer.

There is no environmental reason at all to chose a Prius over the Aygo/C1/107 trio. None.

My 120d with stop start works really well in the city and my emissions are a very low 128g/km.

Just to highlight the point made above - adjusting my driving style for a fortnight and relaxing my foot I get 3 extra days worth of fuel! The average now at around the 60mpg mark. Not bad for a car capable of 0-60 in 7.5seconds when you want it.
