I was astonished at the size of car being offered with these new, smaller turbo petrol engines.
IOne in particular that I got given on a work trip a while ago : Ford Mondeo. 1 litre ecoboost engine (125PS), in nearly 1.5 tonnes of car. I seriously wondered if the (electric) parking brake was stuck on. You have to rev the balls off it to pull away, slipping the clutch as you do so. I'm sure it works fine in the Fiesta, but the Mondeo is a ridiculously large and heavy car to have such a small engine fitted.
Merc seem to be going the same way, with a 1.6, 136hp engine in the 1.5 tonne C class.
BMW offer the 318i - a 1.5 litre, 136hp engine in a 1.4 tonne car.
Audi's A4 is probably the most sensible - and backed up by reports on here from owners with the same engine in other models - the 1.4TFSi, 150hp engine in a car weighing 1320kg.

No, it's the same, lots of revs and clutch slip required, made worse by the off-beat noise of the 3 cylinder. Ok once the revs get up so that the turbo starts spooling but below that--nothing! I can't imagine 1) Ecoboost clutches lasting nor 1.0 Octavias for example. But I read that the downsizing trend doesn't really work and the next idea will be bigger, possibly Atkinson cycle with electric motor support.

Go drive a small Suzuki like the new Ignis. Modest power from the engine but it's very light. I'm enjoying ours a lot.

Rather like these. Nice to see a firm put a bit of effort into their superminis.

I drove a Suzuki Celerio with a NA 1ltr engine (68bhp) for a day or so as a courtesy car and found it quite nippy around town, probably because its a small, light car like the i10 & Co, far, far better off the mark than my old MY96 Micra which only developed 54bhp from the same size engine. It ran out of puff on the dual carriageways going up inclines, but stil...
I also don't like the long gearing of modern cars which is designed for fuel efficiency - the mk1.5 & 2 Mazda 3's 1.6 engine was essentially the same as my mk1's but remapped in this way, losing over a second in 0-60 time and being less well regarded, and for me, partly the reason why sales (relative to other Mazdas at the time) of the 3 declined. Even my Dad's MY09 Fiesta 1.25 has less go in it than the previous gen model (same size engine) he owned.
I'm wondering whether part of the 'problem' is that modern petrol engined cars are all 16v, and many have been VVT or similar, whereby to get any reasonable performance, you need to give them a lot of right foot. Another poster's comment about clucth slippage due to no go without this is, I think, bang on the mark - my Mazda has this issue and I think contributed to the clutch only lasting 60k miles, despite it mostly being used on longer journeys.
I also find that throttle control is more difficult than I used to find, especially when in slow-moving traffic, having to engage the clutch to stop the car stalling because dropping a cog (2nd to 1st) would mean the engine screaming and wanting to rocket away. My old Micra could (once warmed up) tootle along with often no gas on the flat, whereas the Mazda will be at stall speed even with the pedal pushed down a bit.
Let's hope the forthcoming new EU testing rules (and whatever the UK adopts, assuming we actually leave the EU!) mean that car firms revert back to engine mapping and gear ratios that actually suit the driveability of each car, which in the real world surely would enhance both performance and mpg (no labouring of the engine of slipping the clutch, for example).

Atkinson cycle with an Electric motor...like the Prius and other Toyota Hybrids have had for about twenty five years plus? That's the big new idea?

I did not know that, you have surprised me. Am I correct in saying these are not turbo engines?

Exactly! Toyota have been ahead of the game for years, despite motoring journos best efforts to diss the technology. They must be rubbing their hands, being so well placed for the next 50 years!

Hybrids are a stepping stone to pure electric cars. The move to pure electric is happening far quicker than anyone (including me) predicted and as far as I can see Toyota is not a major player in that. A year ago I was saying on here that range-extender hybrids (as opposed to the Toyota Synergy type) would be the future. Now it looks like pure electrics are the future.

Still a lot of work to do on range and recharge time before EVs move out of their current niche of those owners who's vehicle usage pattern fits the current EV restrictions.

Lot of work going to be needed on cost too, who's going to fork out £30k for a car that will need what? £5k's+ worth of new or recon batteries at 5 years old or is basically worthless as a sale proposition.
It all looks lovely at the moment, warm days, only a handful of people using public recharge points, no taxes on the fuel as such, well certainly not in the 50% region that petrol and Diesel have, that happy situation isn't going to last.
Anyone who's been caught out in a real British winter where there's a possibility you might not make it home at all and face the possibility of being stuck overnight, will not want such a device as their only transport option, then chuck a few power cuts into the mix as our creaking generation system can't cope.
Probably fine for well heeled urbanites who have good facilities at home and work, but i can't see many rural dwellers or mixed usage drivers opting to pure electric in a hurry.

One of the other issues associated with cars changing from full petrol/diesel to hybrids and full electric was examined on that recent BBC2 'future predictions' programme (Horizon?), as the worldwide amount of Lithium is small and very dificult to cheaply recover from old batteries as well as get out of the ground (most comes from somewhere in South America if I recall correctly), and so we could run out in a few decades if we can't find a suitable alternative to replace and likely add to dwlindling supplies if more batteries are needed - mobile phones and computers included.
I agree about the charging problems, especially in more rural areas, never mind poorer urban areas where electricity firms wouldn't see any incentive to spend £Bns to lay yet more cables in the road and provide suitable fast charging facilities for every home, government facility and private business - richer areas, yes, poorer/rural ones (just like broadband [never mind fibre] and 3G/4G mobile coverage), no.
I think it would take a significant step forward in both battery technology, electricity generation capacity (new clean, plentiful, safe and cheap fuel sources for everyone) and distribution/end-use charging points for the world to go fully electric. I suspect part of this will include revolutions in many other areas to reduce the electricity demand (higher product efficiency), especially as developing nations get richer and demand for energy-hungry electronic devices increases rapidly in the next 50 years.
In the meantime, any new emissions regulations needs to be reasonable, especially in the light of the recent 'defeat' software scandal, so that investment in new technology to reduce CO2, NO2 and particulate emissions and improve mpg is not strangled, but manufacturers are given clear guideance as to what they need to achieve and the direction as to how to market their vehicles - being environmentally responsible whilst giving selling cars that are driveable and affordable (theat is just as much an issue now that so many people are in my view buying cars on credit that they really can't afford).

Its already started with the 1.5 TSi EVO engine from VW. Its a Miller cycle engine with variable valve timing, variable geometry turbo and cylinder shut down. The Atkinson and Miller cycles are virtualy the same. I've never seen one but it can be ordered now in the Golf estate, but its expensive at £700 more than the 1.6 TDi.

For the past three years, Toyota have been using engines in their non-hybrid cars which change from the Otto to the Atkinson cycle when running under low loads. The 1.0 litre used in the Aygo and the Yaris, and the 1.2T used in the Auris and C-HR.

My first car was a 1980 Ford Cortina 1.6 estate, with a 4-speed manual gearbox.
I think the engine power was something like 60 horsepower, or maybe 80. Definately well under 100 though. I suspect the car weighed around 1 ton or perhaps a bit over.
It was no ball of fire, but I had no problems pulling away at all, even on really steep hills. There was no need to rev the nuts of it or slip the clutch excessively.
So why do modern cars with a higher power to weight ratio have problems? Is it that the modern design produces less torque at low revs?

The 1.6 Cortina engine was 8 valved, carburettor fueled, mechanical distributor, about 72 bhp at 5200 rpm, maximum torque 87 ft/lb at 2700 rpm.
My i30 1.4 litre engine is 16 valves, fuel injected with electronic mixture and timing controls, quoted as 109 bhp at 6200 rpm, maximum torque 101 ft/lb at 5000 rpm.
So my engine, with 87% the swept volume, produces 51% more power and 16% higher torque, the big difference is the rpm at which these are produced.
Crucially also, a Cortina weighed 1005 Kg/2216 lb, an i30 weighs 1193 Kg/2630 lb, 19% more.
The modern engines are more thermally efficient and economical, but to get full performance you need to wind them up to rpm levels which, if you grew up with 1950's/1960's/1970's cars, seem like thrashing them within an inch of their life.
