J.D. Power launches EV Index; measuring roadblocks to EV adoption, parity to gas-powered vehicles

J.D. Power has introduced the J.D. Power EV Index, an analytics tool to track the growing EV market in the United States. Each month, the index will arrive at one number (on a 100-point scale) to make it easy to understand the progress to parity of EVs with traditional internal combustion engine (ICE) vehicles. Whn the index hits 100, parity has been achieved.

The sub-category numbers will represent all the roadblocks to parity. On Tuesday, the EV Index score was 47 (based on the most recent available data from November 2022), with some categories improving and others declining during the 12-month pilot period. The EV Index score and accompanying analysis will be available monthly.

Millions of data points are aggregated into six specific categories to make up the EV Index:

  • Interest. This factor measures the potential commitment to purchasing an EV based on voice of the customer and online behavioral data. The Interest score is 32, up 8 points from a year ago in the pilot phase, due largely to the growing number of EV models available or soon coming to market.

  • Availability. This factor measures the proportion of new-vehicle buyers who have an EV purchase option that meets their buying needs, reflective of factors like price, manufacturer origin, segment and other inputs. The Availability score is 30, up 12 points year over year due largely to the ongoing introduction of EV models into new and important segments.

  • Adoption. This factor measures the proportion of new-vehicle buyers who purchase an EV, relative to those with a viable substitute meeting their needs. The Adoption score is 22, down 4 points from a year ago primarily because the expansion of EV model availability is outpacing EV retail share.

  • Affordability. This factor measures the total cost of ownership of an EV compared with the ICE segment average (after tax credits, rebates, incentives, operating costs and residual values—for both purchase and lease transactions). The Affordability score is 84, down 12 points year over year as EV prices have increased and 15 models were disqualified beginning in August when the Inflation Reduction Act’s North America manufacturing criteria kicked in. The Affordability score is expected to change dramatically based on January 2023 data as the manufacturers’ volume cap is lifted, but vehicle price thresholds and income limits are factored into the purchase of an EV. Leasing, which is currently at 10%, also is expected to grow because the criteria is less restrictive for leasing.

  • Infrastructure. This factor measures the availability, location, speed, and quality and reliability of EV charging compared with gas stations for ICE vehicles. The Infrastructure score is 27, down 4 points year over year primarily because the volume of EV units in operation is outpacing the rate of reliable charger installations.

  • Experience. This factor measures owners’ overall satisfaction with their EV, including appeal, quality, durability, range and the sales and service experiences, as compared with an ICE vehicle equivalent. The Experience score is 89, down 2 points from a year ago due largely to declining satisfaction with the EV sales experience.

The EV Index is hosted on a web-based portal equipped with visualizations, a simple-to-understand dashboard and a custom query tool that can help stakeholders make faster and more reliable decisions.

The new service also includes substantially increased data granularity in which metrics are available at the national, regional, state and Designated Market Area (DMA) levels, and can be broken down by segment, brand and model.



It would be interesting to do this on a country by country basis, as well as a time basis in 1 country.


Interesting but unclear where the data comes from - general public? sophisticated users? industry insiders? EV 'devotees'?
The big issue with such a questionnaire is in the sophistication of the source. Often, a company will ask 'what would need to happen for you to adopt' (with an option of 'never') so as to establish reliability and sophistication of the target. The range of answers may include unlikely possibilities, so determining path forward, if any, is important. Otherwise, a positive first approach to 'sentiment'.


@Jer, good point, different nationalities might interpret the questions differently, so the results might not match country to country.
However, if you did several countries over several years, you would see trends, probably different trends from country to country, which might be interesting (and useful).


We do a survey in the US. For us, the more important question, similar to what Jer posts above is: Are there any obstacles to you driving electric. If so, what are they?

The issues can be addressed in a policy level and/or on a personal level.

In my view, it’s not a matter of reaching parity unless you’re taking into account the externalities like air quality and climate change, which these models almost never do. It’s a matter of reaching a person’s set point.

If you’re fighting a culture war, parity isn’t the issue. But reaching someone’s set point is.
