A current EV progress report by Deloitte gets key details flawed, ignores Tesla, and tasks EV progress charges to be drastically slowing, glacial, after reaching simply 20% of market share in 2030. And these guys name themselves professionals? Let’s assist them out.
Extensively coated in the tech media, often without evaluation or critique, Deloitte’s current EV market progress report is filled with holes and primary factual errors, which they leverage to help a downbeat assessment of EVs’ long-term prospects.
Since Deloitte cited CleanTechnica as one among its sources (backside of web page 10 of the complete report), I felt responsible to help them out of their confusion and set them on a straighter path. I’ve contacted the report’s lead editor in addition to one of the key authors, however haven’t yet acquired any strong explanations for the discrepancies.
The Deloitte report sensibly takes the position that EV mass-market demand will depend upon EVs offering acceptable efficiency in the important thing areas of: driving vary, total-cost-of-ownership (TCO), and DC fast charging speeds (and infrastructure):
“…the four most important customer concerns regarding BEVs are: driving range, cost premium, lack of infrastructure and time required to charge.”
Thus far, so apparent. Their key error, nevertheless, is to significantly misunderstand and misreport both the performance on these key metrics of EVs on the street at present, especially the efficiency of Tesla’s automobiles, and the speed of enchancment in these key metrics of EVs coming later in 2019 and subsequently. The report’s errors, confusions, and omissions embrace:
- Rookie errors and confusions concerning the range of EVs (and excluding Tesla’s Mannequin 3)
- 5 years behind the curve on the evolution of DC charging speeds
- Errors understanding the important position of battery value ($/kWh) on EV range (they as an alternative claim technological hurdles)
- Arbitrary and unsupported evaluation of the TCO of EVs, downplaying TCO parity with gasoline/diesel automobiles
Whether or not these are genuine rookie errors or deliberate misstatement of details within the service of an general picture of EV FUD is tough to say. It’s potential that they simply misunderstand the present state of EVs and their speedy evolution. It’s also potential that the multi-author, multi-editor nature of the report just did not catch errors and unrealistic projections. We’ll analyze the errors themselves in additional depth under. For now, let’s take a look at what unrealistic conclusions they lead Deloitte to attract.
When it comes to the large picture of EV progress rates, Deloitte gets a minimum of one factor proper — the historical figures on the growth in EV sales over current years. Their historical progress figures match the industry-leading gross sales reviews by our associates over at EV Volumes. Though EV Volumes doesn’t yet have an official report on 2018 complete EV gross sales (at time of writing), Jose Pontes has indicated that it’ll very doubtless be over 2 million automobiles worldwide. Deloitte is knowledgeable nicely sufficient to make use of this as their 2018 determine. (The EV gross sales figures embrace both pure EVs and plug-in hybrid automobiles.)
The chart exhibits a mean 5-year progress price of ~56.66% yr over yr. Within the period from 2016–2018, the growth fee developments additional upwards to a mean of 62%. Deloitte knows this, since it has the identical knowledge and used it for the report’s charts. What then do they challenge the longer term sales numbers shall be within the coming few years? Let’s have a look:
Notice that Deloitte’s knowledge for 2017 and 2018 are historically accurate. Any differences right here will not be as a consequence of totally different interpretation of gross sales numbers prior to 2019.
On first look, this seems like a fairly normal graph. On nearer inspection, in plotting the info as the corporate does, Deloitte is assuming that the historical progress over the previous several years — as much as and including 2018 — is about to drop off very significantly.
The green knowledge present the historic progress price (56.66%) persevering with over the approaching years. For Deloitte (the pink knowledge), it’s as if the expansion to date was a fluke and, after 2018, Deloitte tasks that progress slows and slows. You possibly can see that, for 2019, Deloitte’s pink bar is instantly down on the current progress development projection depicted in the inexperienced bar. In figures, its progress projection drops from the current 5-year common of 56.7% to only 37.5% in 2019. From there, it solely gets worse in Deloitte’s prediction. Here’s the corporate’s complete 12-year forward projection in year-on-year % progress phrases, plotted towards the year-on-year % progress rates that have traditionally been recorded:
Deloitte sees EV progress fee immediately dropping from current 5-year 56.7% year-on-year average and shortly trending to zero! Down, down, down! Doom and gloom. There’s a small uptick of progress around 2023 and 2024. That’s around the time they claim EVs will achieve TCO parity with fuel/diesel automobiles (we at CleanTechnica assume it’s a lot earlier, discussed under). Deloitte predicts around 9–11% market share for EVs in 2023–24 (under graph). After this, nevertheless, EVs apparently must get relatively less engaging, because EV progress drops off a cliff, trending into single digit % progress after 2027, based on Deloitte. This declines additional, trending in the direction of zero progress from 2030 onwards, after EVs’ general market share has approached 20% (see graph under).
Why does Deloitte make these predictions? Is there a purpose why its analysts assume EV progress grinds virtually to a halt after 2030? Perhaps they assume decreasing carbon emissions will not be a priority, we’ll all come to simply accept inevitable unbridled local weather change by that time, and need to speed up ourselves off the edge of the abyss? Or maybe they assume we’ll just miss the noise, vibration, sluggish response, mechanical complexity, and high operating prices of inner combustion engine (ICE) automobiles and turn back in the direction of them?
Here’s a graph of Deloitte’s complete EV sales projections out to 2030, in comparison with a projection based mostly on current progress developments and together with a conservative middle-ground place that I’ve pencilled in:
The gray bars in the chart characterize Deloitte’s projection of EV manufacturing capability over the approaching years. It’s clear that they assume demand for EVs, and thus gross sales (the pink bars), might be considerably lower than the manufacturing capability. You possibly can see clearly their assumption that any progress in EV sales will taper off in the direction of 2030. On the idea of those projections, Deloitte’s remaining conclusion is subsequently to warn automakers that there gained’t be adequate demand for EVs going forwards, and thus their investments for EV manufacturing capability are unwise. Perhaps Deloitte’s report is aimed toward ruffling some feathers and getting automakers to turn to them extra regularly to get their cautionary advice on the way forward for the auto industry.
No one is aware of for positive what the longer term holds. We try to make affordable assumptions based mostly on what we know of the past and the present, and the tendencies and dynamics that we see emerging. We will, nevertheless, have a look underneath the hood of Deloitte’s assumptions and understanding of the key dynamics, because the agency shares its evaluation of these within the report. I agree with Deloitte that succesful range and recharging, at competitive value, can be key to EVs gaining ever extra market share. As I mentioned above, nevertheless, there are various obvious errors in how Deloitte analysts learn the current status of those elements, and obvious errors of their consciousness of the current evolution of EVs. Let’s break down their errors in additional detail.

Rookie Errors & Confusions concerning the Range of EVs (and Excluding the Tesla Model three)
Deloitte analysts are noticeably inconsistent in reporting the range of present and upcoming EVs (page 7 of their report). They state that they’re using (the outdated) NEDC range, but their knowledge set truly makes use of a combined array of metrics, and this error made it via the modifying process. It’s a hotchpotch of the extra practical EPA vary metric, the unrealistic WLTP metric, and the primarily useless NEDC metric. For instance, they listing the forthcoming Tesla Roadster as having 1,000 km (620 miles) of NEDC range, when the truth is this shall be its EPA range, a very totally different metric.
No matter metric Deloitte uses or confuses, it studies the Audi E-Tron (512 km) and Mercedes-Benz EQC (500 km) as having larger vary than the Hyundai Kona EV (420 km) and Kia e-Niro (470 km). This doesn’t match these automobiles’ official NEDC scores nor the WLTP scores (e.g. Kona 449 km WLTP, 546 km NEDC), and most certainly additionally misrepresents their relative performance based mostly on their upcoming EPA scores. For example, the Kona has an EPA range of 258 miles, the Niro 239 miles — the reverse of Deloitte’s ranking. It’s highly doubtful the e-tron or EQC might be EPA rated at as a lot as 258 miles EPA.
Deloitte additionally fails outright to listing the Tesla Model three or Tesla Mannequin S, which are extensively recognized to be the present range leaders of all EVs. No purpose is given for this. One cause could be that Deloitte’s shoppers are principally European automakers who have already had sufficient of listening to about how attractive Teslas are.
5 Years Behind the Curve on DC Charging Speeds
Deloitte state on page 9:
“We estimate the time required to achieve an 80 percent charge in a 60 kWh battery (equivalent to a range of 200 miles) will be reduced to just 30 minutes — the threshold the majority of customers consider acceptable — by 2025.”
In actuality, if we’re setting the bar at recharging 160 miles (80% of 200 miles) of range utilizing the generous NEDC metric, the 2019 Hyundai Ioniq, coming in the second half of this yr, already matches the bill, greater than 5 years ahead of Deloitte’s projections.
Its NEDC range is 235 miles (378 km), and it could actually recharge 80% of its 38.three kWh battery pack in underneath 30 minutes. Its more real looking EPA vary score will doubtless be around 170 miles, nevertheless.
Then there’s the Tesla Model three Lengthy Range and Mid Range. The Long Range can already add 198 miles of range (EPA) in 30 minutes, and greater than 200 miles in Deloitte’s most popular NEDC-equivalent metric. The Mid Vary can add 177 miles (EPA) in that time. Perhaps Deloitte imply that the 80% charge is the equivalent of 200 miles range? When the Tesla Supercharger v3 arrives later this yr, both these Tesla models will doubtless achieve over 200 miles added in 30 minutes.
And then there’s the Volkswagen ID, arriving in late 2019 or early 2020, all variants of which are claimed to have over 200 miles of WLTP range (not to mention NEDC range) and capable of including 80% charge in beneath 30 minutes.
Briefly, the Deloitte report’s “estimate” about 2025 charging speeds is already outdated based mostly on what the Tesla Model 3 might do in 2018, and what a number of other EVs will do in 2019. Including 160 miles of vary in 30 minutes is already turning into the new regular in 2018–2019 and 200 miles is what at the moment’s leaders can achieve. By 2025, the norm might be adding 200+ miles in 20 minutes (or better). What was Deloitte considering by itemizing 2018–2019 specs as an necessary aim for EV acceptance in 2025? This facet of the report seems to be completely out of touch with actuality.
Missing the Position of Battery Value on EV Range, and Suggesting Know-how Breakthroughs Required
Keen on the concept 200 miles of vary is a useful efficiency to purpose for, the Deloitte report will get artistic on web page 7, giving us a helpful sounding part titled, “Next generation BEV driving range explained.” It factors to evolving battery materials and cell chemistries, optimizing pack designs, pack cooling, and BMS improvements. It even appears past 2023 to exotic prospects like lithium-air batteries and solid-state electrolytes. All sounds very exciting!
Presumably, then, giving EVs respectable 200+ mile vary depends first and foremost on these scientific and technical enhancements and breakthroughs? It’s a question of physics multiple of value? Nicely, no.
Tesla has already confirmed that 300+ mile vary is on the market of their mid-sized Mannequin 3 sedan (in 2017, truly). Smaller nonetheless, the Chevrolet Bolt (2016), Hyundai Kona EV, Kia e-Niro, 2019 Nissan LEAF, and upcoming 2019 Volkswagen ID all have ranges comfortably over 200 miles, and over 250 miles in some instances. Obviously, the power density of batteries is already previous the point of allowing very respectable vary in these modestly sized automobiles. It’s not primarily a query of physics and technical breakthroughs, though chemistry improvements can scale back prices by making the same amount of uncooked materials “go further” in power terms. But the overarching level is that long-range EVs usually are not a challenge in know-how phrases — they are primarily a problem in simple value terms.
Whilst gradual enhancements to chemistry may help scale back value, more relevant are optimizing manufacturing processes and volumes, optimizing cell geometry, and so on. These essential priorities are nowhere discussed by Deloitte, but fortunately it’s a topic that we talk about repeatedly right here on CleanTechnica.
The brief model is that battery prices ($/kWh) have been decreasing at round 15% per yr for the past few years, and we anticipate this to continue onwards, with Tesla concentrating on breaking by means of $100/kWh on the pack degree across the end of 2020. LG, CATL, and different battery makers are additionally doubtless not too far behind. Does Tesla spend much time talking about battery chemistry breakthroughs? By no means. It has truly dismissed the concept breakthroughs are vital (gradual enhancements, sure, but not breakthroughs) — it’s all about growing scale and steadily decreasing prices.
Arbitrary and Unsupported TCO Analysis of EVs, Downplaying Parity with Gasmobiles
Deloitte’s declare that an EV compact automotive driven 7,900 miles a yr reaches TCO parity with a gasoline/diesel automotive by 2022 (truly, they are saying 2021–2024, relying on incentives) isn’t accompanied by any arduous knowledge on value calculation to again it up. Our own analysis here at CleanTechnica (and right here and here) has shown that, in lots of situations, EVs’ TCO was already higher than fuel automobiles’ TCO in 2018 for mid-sized segments (and pretty much each phase above). That is within the US, the place the gas-price to electricity-price gap (an enormous a part of EV TCO savings) is comparatively low compared to other areas. Without Deloitte’s TCO claim being supported by clear knowledge, we will solely decide this facet of its timeline to be downbeat in comparison with different analyses.
The most important a part of TCO is a car’s worth depreciation. ICE automobiles are on the cusp of having a miserable future on this respect, simply as the present era of all-round competent EVs are topping the value-retention charts. Worth retention is just going to get better for EVs and worse for ICEs from right here on out. That is additionally a topic we’ve commonly coated. More broadly, given the inexorable battery value reductions talked about above, we will anticipate just about all mainstream car segments to be at sticker worth parity with ICE by 2024. Given the considerably lower operating costs of EVs, this puts TCO parity far prematurely of 2024 for many automobiles.
Deloitte prides itself on being the most important “professional services network” on the earth by income, and its current report presents itself as a forward-looking and authoritative view over the future of the EV market. For my part, nevertheless, based mostly on what I’ve introduced in this article, the standard of the info in the report is poor and incorporates vital errors. It appears to be badly researched, and filled with perspectives that resemble rookie errors. Based mostly on the faulty knowledge, Deloitte has anaemic projections about EV progress. Its conclusions are downbeat, yet unsupported, unjustified, and out of step with realities on the bottom. Provided that the conclusions might only be justified on the back of the report’s faulty knowledge, this report definitely has the end result (meant or not) of selling misguided worry, uncertainty, and doubt (FUD) over the way forward for EV sales progress.
Comparable studies promoting FUD about EVs have been revealed earlier than, and will possible more and more seem over the coming years as EVs inevitably seize more and more of the market, and disrupt more and more of the legacy auto industry. It’s greatest to either ignore them or learn them with a important thoughts.
Should you can spot more errors within the Deloitte report, please share your findings (and other ideas) within the feedback.
