In the Awards 2012 edition of What Car, they include an article on the new Mondeo. Although Ford haven't confirmed that their three cylinder one litre Ecoboost 123bhp engine will be going into the Mondeo, thay did confirm it is being tested in larger cars. What Car think that it is a foregone conclusion that engine will replace the current 1.6 litre 118bhp engine.

Doubt it'll make it past the concept stage.

There's no technical difficulty in extracting 120 odd horsepower from a 1.0 litre t/c petrol-with a reasonable torque band to boot.

But the NVHproblems of a heavily loaded 3 cylinder engine are horrible at low RPM. In such a heavy car You'd also spend too much time on boost and end up wasting fuel with enrichment and spark retard issues. There's a definte limit in how far downsizing works to produce effective fuel savings.

Agreed - if you took it to even more extremes, the engine becomes a jet engine which simply uses the pistons/crankshaft to convert the exhaust power into shaft energy - now at constant load/rpm jet engines can be economical but have never been suitable for car use.

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

Jet engines have never been more than novelties in the sub 100kW size range. As far as small engines are concerned (sub 100kW), the piston engine is very tough to beat since it is fairly efficient at converting chemical energy directly into useful rotary motion with only mild speed reduction required. This never seems to stop people looking for novel 'solutions' to a problem that is largely non existent. Such efforts are in vain unless one has a thorough understanding of the status quo.

Is it one litre in size or in the European measuring system one litre per hundred kilometeres one sounds very undersized and the other very very economical.

A whole litre? Profligate!

500cc of throbbing power should be plenty.....

~1000cc 3-pot with a turbo.

Better than the worthless 1.6Ti-VCT 115hp lump they're using now, Makes my old 125hp 1.8 Mk3 Mondeo look like a rocket ship.

@ Unthrottled - true, but it would be cool to own a jet car.

This is a good read: http://www.turbinecar.com/sia/sia127.htm

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

Would it?

In the same way that high revving naturally aspirated engines 'sound' exciting because they make a lot of noise, whilst a turbo engine quietly does the same job (or better) with less fuss.

I demonstrated this to a colleague extolling the merits of the his VTEC engine. After some persuasion, I convinced him to take the car for a spin and then wind the engine up to seven grand, then switch the ignition off, with the car in gear. The look on his face when the engine note didn't change a jot was priceless. All that 'power' was just the pistons heating up the engine oil!

Psycology plays funny tricks on our perception of reality.

Cars keep getting bigger and heavier yet carmakers in their infinite wisdom keep making engines smaller. How does that work?

Im sorry a 1.0 Mondeo? I heard about this engine going into the new Focus and as good an engine as it might be im not convinced about it even in that.

Ford Mondeo - 1 litre Ford Mondeo - RT

And we used to think the 957cc engine was underpowered in the Fiesta when it was announced - and the Fiesta was half the weight of a current Mondeo.

Ford Mondeo - 1 litre Ford Mondeo - jamie745

I found the 1.6 in the mk2 Focus to be too weak, especially with quite an average automatic gearbox.

Im quite happy with the 3.0litre Jaguar V6 :P

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

The turbo changes the equation though. Probably a flat torque curve from 1500 through 4000 RPM. Top end power of a good 1.6 VVT and the torque of a n/a 1.8-2.0. Hardly stellar, but not terrible.

No, the problem is NVH. Drivers just won't accept the characteristics of a boosted 3 cylinder at low Speed-so they'll hang onto the lower gears to mitigate it. A 3 cyl at 2000 RPM has similar friction/pumping losses to a 4 cylinder at 15000 RPM-negating any fuel economy benefit.

Engine designers have been toying with boosted triples for years because, on paper, you get better economy. But there's a reason that they've never got past the econobox sector.

Treat 'new' ideas in engineering with suspicion; there are very few genuine new ideas. Sometimes advances in electronics or materials science allows old ideas to be revisited. But usually 'new' ideas are simply old ideas hat have been investigated and dismissed with good reason.

FIAT, of course, has a boosted twin which produces remarkable power for a sub-900cc engine. I think it's a hoot but the engine note and power delivery characteristics are decidedly Marmite and if you drive it with brio then it's not that economical.

It will be interesting to see if Ford has similar results whatever vehicles this interesting engine ends up in.

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

85hp from 900cc works out at 94.4hp/litre. Hardly remarkable!

New cars are now getting lighter, they may be slightly larger, but not heavier.

Personally i wouldnt want a car without a turbo, as they make short work of any hill, and are much more relaxing to drive.

The new Mondeo looks ugly compared to the present model, which looks great in the right colour.

I think 1.6 may be ok, but a three pot 1L, not for me.

1977 Ford Fiesta 1100 weighed in at 1660lb

New Kuga is lighter.

New CRV is lighter.

http://newsuv.org/compact-suvs/2012-honda-cr-v-release-date/

2012 xtrail is 70kg lighter.

And the Mazda CX-5 will come in under 1600kg. Sky active will mean all new models should be reduced in weight.

The Sorento and Santa Fe are also considerably lighter than the previous model.

Haven't bother to check the replacement "45" model

Lots of cars now lose the spare wheel that takes 20kg of.

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

And the Mazda CX-5 will come in under 1600kg.

Woopee doo. A hatchback in drag comes down to 1.6 tonnes. To put that in perspective, it's heavier than a mid 1980's BMW 7 series...

Car weights are starting to come down, but that's against a backdrop of a couple of decades of piling on the pounds.

Ford Mondeo - 1 litre Ford Mondeo - xtrailman

My Mk1 cortina was lighter than the Mondeo. But what's the point of those sort of comparisons?

The Mazda is expected to be lighter than its equivalent rivals, thats what relevant.

1570kg is quoted for one of the heaviest versions, so entry models will be lighter.

This compares well to the same sized car the T30 xtrail. which weighed 1650kg in SVE.

As you know most of the fords have gained size, which accounts for the increased weights.

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

But what's the point of those sort of comparisons?

To gain a sense of perspective. I'll throw just one more in: 2001 Ford Mondeo 2.0i-which everyone will agree is a fairly cavernous car that'll easy accommodate 5 passengers and the kitchen sink. Weight: 2860lb (1300kg).

That car is way is far more commodious than any of those mini-compact-crossover-whatthehellamisupposedtobe wannabe Range Rover thingies. Yet it is a lot lighter.

It isn't really clear what all that weight is achieving-it certainly isn't cabin space. I suppose a half baked 4X4 system engenders a comforting illusion of invincibility.

In short, cars are too heavy for their floorpan size. You yield far better results shedding pounds than you do by trying to play tricks with engine design.

5 passengers? Where does the driver sit? :P I had one of those Mondeo's and the rear space isnt that brilliant, the car will seat 4 with no problem though. It was a good car but i think its 2-star safety rating had something to do with the successor becoming bigger and more chunky. 2 star wasnt too bad when the car was developed in the 90s but it'd be deemed unacceptable now.

Safety features? Stronger construction? Strengthening beams? etc. All of that stuff must weigh quite a bit. My S-Type's door is far thicker and chunkier than the Mondeo that you mention, for instance.

Ford Mondeo - 1 litre Ford Mondeo - unthrottled

I think that outside of the minicab business, the driver counts as a passenger!

I take your point about NCAP safety ratings, but I still think that they are overrated. The trouble with crash tests is that, in order to get good results, you generally have to put strengthening structures in places that interfere with visibility. You cannot deny that the visibility of a lot of modern cars (especially compacts) is dreadful. I'll take visbility over NCAP ratings any day. I'd rather improve my chances of not having an accident than worrying about what might happen in the event of an accident.

If you're paranoid about dying, car travel is not for you!

Ford Mondeo - 1 litre Ford Mondeo - jamie745

I dont quite see your logic. Yes the aerodynamic safety-centred designs cut down on visibility but most accidents caused by poor visibility endanger the person the motorist hits, not the motorist themselves. In many modern cars its easy to reverse over a child, crash into a cyclist obscured by a door pillar etc but i dont feel they cause an increase of the sort of accidents which kill car occupants.

Its worth noting the Euro NCAP test is a 40mph crash into a concrete barrier and its tested on how safe the vehicle occupants would be. The sort of accident which could kill you is the type you'd probably see coming but its the sort of accident where something hits you, not the other way around.

Just because you can see doesnt mean everybody else will be driving properly and nor does it mean you'll be able to do much about it.

The 2010-on Sorento, based on the Santa Fe, is much lighter than it's predecessor which had a truck chassis.

The 2010-on Santa Fe is the same weight as it's predecessor - there aren't any details of the iX45 and iX55 available yet, it's possible that one will be lighter, the other heavier.

The upcoming Range Rover is nearly 500kg lighter !!!

My old man has a 3-pot engine - in his tractor. 2.5 litre 3-pot Perkins diesel, and the vibrations are shocking. It goes through exhaust stacks annually, bracketry is never done breaking around the engine due to metal fatigue, and pipes and wires chafing together.

I don't think I'd want a 3-pot near a car I was driving, thanks.
