But leasing a car is whoefully expensive. You'll pay for the new battery one way or another and the leasing company makes money from you while doing it. Buying a low maintenance cost used car is the most cost effective way to drive & own a car (*). Another major disadvantage of leasing a car is that if something happens to your income, the you are also without transport while you may need it the most. I had one company car in my life. When the company when belly up I had to bring the car back. Even though I could really use it to go to job interview.
* For example: my current Ford costs less than 17 euro-cents/km all in (fuel, taxes, maintenance, annual mandatory check) with the purchase price written off fully. And this is one of our more expensive cars.
Those assumptions are wildly optimistic. 6% increase in battery capacity per year is a commonly used rule of thumb. Not 16! Even a small EV needs way over 200Wh/km and 320km of range isn't enough for EVs to become mainstream at all. The charge time improvement and cost of the charging infrastructure are also missing.
Leasing or financed if something happens to your income you are screwed either way. A Ford is considered an expensive car? Not here in the US. A Ford in the US is just an average car.

Even a small EV needs way over 200Wh/km and 320km of range isn't enough for EVs to become mainstream at all. The charge time improvement and cost of the charging infrastructure are also missing.Why on earth can't they just put some simple and humble Briggs & Stratton in there for the rare occasions you need more range? 6.5 hp B&S costs next to nothing and would propel small car just fine if you start it before battery goes totally flat. You would never have to worry about battery going empty and could charge anywhere in a emergency.
Car makers just have too much engineers designing utterly complex and expensive solutions for simple problems. Then they wonder their products costs so much people don't buy

Say in BMW i3 REx ICE develops 34 hp. And still on electric charge + full gasoline tank it has lower range than any Tesla.

Must be smarter than Tesla. Yeah, engine, generator, fuel tank come for free, I guess. Also they don't consume any space and don't add any weight. They supposedly don't need any servicing as well. And guess are not useless dead weight most of the time .
Not to say that if you start 6.5 hp engine while battery is still full (which would make no sense), it would give like 50% range increase in the best case. If started when say 30% of the charge is left, no significant range extension would be achieved at all. And then you'll be stuck while it charges the battery in a slow pace.
If you want to buy PHEV where battery capacity is compromised with a presence of ICE, you have a choice.

The quickest an EV can refill is at 2 kWh/minute (*) (a tesla @ a supercharger @ 120kW), but any ICE can do it at ~ 400 kWh/minute (40 litres/minute), that's 200x times faster.
(*) Accounting for losses the real figure is ~ 0.85 times that = 1.7 kWh/minute, or 235x slower than any ICE.
2) Your figure for gasoline energy density is high. 8.7 - 9.7 kWh/l are the numbers I’ve seen.
20% is for the good old gas guzzler. Modern efficient ICEs are doing 35% comfortably over a wide load range.
The figures are for diesel/gasoil: 35.8e6[joules/litre]*40[litre]/3600[seconds]/1e3 = 397.7 kWh
40l/minute is way higher than my average experience which is more like 3 to 4 minutes for 60 litres. Perhaps with the highvolume truck gauges.
Light passenger vehicle pump flow rate ranges up to about 50 litres (13 US gallons) per minute[3] (the United States limits this to 10 US gallons (38 litres) per minute[4]); pumps serving trucks and other large vehicles have a higher flow rate, up to 130 litres (34 US gallons) per minute in the UK
The figures are for diesel/gasoil: 35.8e6[joules/litre]*40[litre]/3600[seconds]/1e3 = 397.7 kWhBut you said *any* ICE. Diesel cars are a tiny percentage of US autos.
But Diesel engines are what moves the world!

OK good to know - but of course still much less efficient than an electric motor..
In any case, the underlying comparison is not really valid since electricity can be delivered directly at home and gasoline cannot.
It only becomes relevant for car trips > 200 miles or so, which represent a very tiny fraction of car trips -probably < 0.5% or lower. ( In the US trips > 100 miles are < 1% )
From the generator to the wheel of an EV about 30% of the energy is lost as well.
You can have all the fuel delivered to your home if you want. Just order it.
But then you'll need to own multiple cars

1) Most people could never install the required large fuel storage tank and even fewer live somewhere that it would be permitted.
