Two key factors regarding EV range: Speed and battery capacity.

Battery tech in 10 years from now will be completely different than it is now, so I expect a huge increase in REAL WORLD driving range. Also, if speed gets limited (Audi e-tron limited to 200 kph, many EVs will follow), this adds even more range.

The real issues at hand are charging infrastructures and speed, resale values and cost. Not sure how they are going to sort out these issues. Most people in Germany (and many other countries) live in condos, they have no real possibility to charge their EVs over night. Also, nobody wants to wait 15 minutes or longer (current charging tech) at a charging station to get a full charge. Also imagine the same number of petrol/Diesel cars at your busy fuel ststion needing a charge at a charging station. A charging station would need to accomodate at least 100 cars at the same time, probably more, to achieve the same efficiency. This may not be a problem in the US with their wide areas but in Europe? Huge issue.

Very challenging times ahead if we really want to switch to EVs. In Germany, right now, the EV market is "dead", this is why I am seriously worried about VW Group's plans to push forward with EVs. Hybrids seem to be, for now, the more viable solution.

Battery capacity will not be that much greater in ten years because annual improvement is averaging 3-5% per annum based on the current technologies with much of the gain focused on cost efficiency, not capacity.  Even solid state LiB do not significantly increase capacity, only faster charging rates and lower costs.   LiBs are restricted to the rate of innovation in chemistry, not semiconductor physics found in electronics.  Cellphone battery life has increased more through manufacturers making larger phone, thus opening space for larger batteries than greater charge increases for similar sized batteries.   

The storage issue is why most manufacturers have looked toward crossovers for their higher range models than smaller vehicle classes; a larger vehicle can hold a larger battery pack.   The energy profiles of vehicles are highly developed with little to be gained in the future.   Every automaker knows what the energy consumption is for every speed, vehicle load, and weather condition, so there is little to gain on that front.   Therefore, the burden falls on the slowly developing battery packs coupled with a greater charging infrastructure to increase long range viability for the EV.

In theory,  hybrids do provide a potential upside to the consumer by providing the benefits of EV and the ICE; however, in practice, the new global regulations make hybrids less cost attractive.   Regulations are making EVs more attractive from a cost standpoint than PHEVs, since a larger battery pack is required to meet the new CO2 emission levels.  Most manufacturers are fixated on costs and corresponding profit margins to remain in business.   As Bob Lutz stated in the recent Autoline podcast, consumers are more interested in monthly payment pricing than the overall price of the vehicle.  This market preference forces the hands of the manufacturers to meet certain cost parameters that eliminate elements of technology.   It is the market that drives, in more than one way, the product versus the manufacturers.
