Engine Sizes

I don't care what size an engine is, as long as it makes the figures that I want.

Small engines can make huge power if done cleverly, old F1 showed that ...

He means VW and and Fiat dont make supercars because they own companies like Porsche and Ferrari

Look at it the other way. The average for Ferrari and Porsche is extremely high, this is offset by the bucket loads of Bluemotions and Twin Airs that will be sold through their parent companies.

They also did 3 laps if they were lucky, raced with less power than the last of the line 3ltr v10s and had no regard to driveability and emissions.
 
Some can be made very reliable, but it costs money especially if you blur the lines between ICE and turbine
 
Here we go. This guy talking crap again... I just can not tolerate it!

Rypt go somewhere where you cant wind everyone you. I suggest a copy of SIM city where you can act out your meglomaniac desired to establish utopia.

Up and down blurred with spinny whizzy, with reliability and cheap for cars? Just which crack-pot university are you making engineering up at?

Yep, Fully understand your point.

Who is causing more harm than good?

Those few in the super cars..... Or the many tens of thousands in their toyota pirus' lol

I suggest you go learn about some of the interesting ideas of what is possible to do with engines once you are playing with compound chargers where the turbine directly drives the crank (so you get no loss due to the compression stroke in the engine), where you compress the air more than would need to and then cool it in an expansion chamber to have the inlet be at -100C, and so on
 
Aston Martin Cynet.

Elaboration: AM must have a massively high carbon footprint, so to balance it out they're bringing out a lovely rebadged Toyota iQ with a 1.33 engine. In fairness, this 1.33 pumps out 98bhp while churning out 110gCO2/km which is rather large improvement over my 1.3(3) 97 Starlet which has 74bhp and 160-170gCO2/km. But I digress...
 
At 30k (3 times the price of a normal IQ) I doubt they'll be for everyone!

They're the IMac pros of the car world!

Like 'old F1' cars ?

You can then get very large volumetric efficiencies due to such cold air, you can make large power from small displacement.

Yes you will need to have good manufacturing techniques and processes to do so reliably, and you will need to design the engine correctly to with respect to oiling and cooling. But it can be done

When turbos were allowed in F1 the, Benneton (well Cosworth) engine was designed to be run at 8bar and was conceived as having a turbine powering the crank.
When the rules were changed to only let it run 4bar boost the engine was change to not have that turbine anymore, but the turbo still made 8bar boost afaik. This was then expanded to give the needed 4 bar of boost at the restrictor.

You'll need to mess around with refrigerants in order to achieve -100C. Something that's not very easy, especially on a mass produced scale. It's easier to increase efficiencies via other methods such as regenerative feed heating.
