There’s a quiet assumption behind the wheel of most electrical automobiles, that slower is at all times higher. Higher for vary, for effectivity, for nerves. And whereas that’s nonetheless largely true, a rising physique of knowledge from real-world EV house owners means that the time-versus-speed equation isn’t so simple as it was once.
Can Driving Sooner and Extremely-Quick Charging Shorten EV Highway Journeys?
With ultra-fast charging and evolving infrastructure, there are circumstances, not suggestions, the place touring at larger speeds could lead to shorter general journey occasions. This isn’t to advertise dashing; it’s about exploring how electrification is subtly altering the way in which long-distance journey works.
One Redditor summed it up fantastically:
“When the subject of vary comes up, there’s at all times dialogue about driving 70 vs. 80 and the way a lot additional you can drive on a single cost. And it is true, the effectivity drop is non-linear, so 70 to 75 loses extra vary than 65 to 70.
Nevertheless, what I believe will get misplaced on this dialog is that the factor most individuals care about on street journeys shouldn’t be the effectivity or uncooked variety of stops, however somewhat time to vacation spot. DCFC is turning into more and more extra frequent, and so long as you do not have to exit of your means and have first rate charging speeds, you may save a major period of time by going 80 vs making an attempt to hypermile to keep away from stopping.
To offer an instance, as an instance you might be driving a car that fees at 100 kW on common, and let’s take the 2 conditions of chilling at 65 mph vs. dashing at 80 mph, over the course of a 500 mile journey. I will be very beneficiant to the slowpoke and say that at 65 mph you may get 4 miles/kWh, whereas at 80 you solely get 2 miles/kWh, and also you begin by leaving dwelling at 0% (simply so we do not have to deduct an arbitrary quantity of charging time from each). Placing this into desk kind:
Even should you add in a flat 5 minutes per cease to get to the charging spot and get fee sorted, it is nonetheless clear that dashing beats going gradual. Plus, these numbers are exaggerated already in favor of the slower velocity, and it nonetheless loses (my private numbers are 3.4 mi/kWh at 65 mph and ~2.5 mi/kwh at 80, no less than in good climate). There is a little bit of calculus concerned in figuring out the optimum driving velocity because the particular relationship between your velocity and effectivity is vital to the calculation, however in virtually each state of affairs I may plug into that calculation above, driving 80 got here out forward on time.
Now, you’ll pay extra, however I would gladly pay an additional $20 to get to my vacation spot an hour quicker.
Edit: Mounted the desk. It was blended up initially, and made the precise reverse level of what I used to be making an attempt to say. Sorry!
Edit2: Because it apparently must be stated, I don’t advocate actually driving 80 mph. If it can save you time driving 80, you can too save time at 75 or 70, even within the worst-case situation I outlined of extreme effectivity loss and comparatively gradual charging speeds.
Edit3: To offer an precise situation from actuality, listed below are the stats for my EV6 from a driving the identical velocity for like ~50 miles at a time on a current roadtrip. I rounded a number of numbers, however that is very near “actual information”. Left at close to 100%, so I am subtracting the cost time. Whole journey miles was 400, and cost velocity was one thing like 180 kW. I am not going to issue within the beginning cost, however you’ll be able to subtract ~half-hour from the cost and complete occasions if you wish to be pedantic.
So in my state of affairs, there’s nearly an hour of hypothetical financial savings, at the price of 50 kWh, which is about $20. Once more, I am not recommending you drive 80 generally, simply that you simply need not drive slower simply because it is an EV.” – chilidoggo, Reddit
That quote comes from a Reddit consumer who not too long ago broke down their street journey expertise in a Kia EV6. At 80 mph, the journey took 5.9 hours and consumed 167 kWh. At 65 mph, it stretched to six.75 hours however solely used 118 kWh. The quicker tempo shaved off practically an hour of journey time however got here with a roughly $20 premium in electrical energy.
It’s not a definitive argument for driving quicker, it’s a situational commentary. In automobiles with quick charging functionality, the additional time spent recharging is perhaps offset by larger cruising speeds, relying on situations.
Actual-World Infrastructure Hurdles for EV Quick Charging Reliability
- Excessive-power DC quick chargers (150–400 miles/hr equal) can usually refill an EV from 10 % to 80 % in about 30–60 minutes. Most fashions prime up roughly 100 miles in 30–35 minutes
- EV road-trippers typically schedule charging stops each ~3 hours (or ~200–250 miles) to match battery absorption charges and driver fatigue patterns.
- For environment friendly pit stops, drivers are likely to cost for about 15–25 minutes, roughly the time wanted for restroom breaks, snacks, stretching, and topping off cost curves .
- If utilizing primarily Stage 2 chargers or stopping for a full meal, pauses can lengthen to 30 minutes (fast meals) or 45–60 minutes (sit-down eating places), partially relying on slower charging charges.
Supporting this concept is an in depth breakdown of the Ford F-150 Lightning’s efficiency over a 1,000-mile journey. At 75 mph, the Lightning made it in 16.58 hours with 4 charging stops.
At 70 mph, it took simply 5 minutes longer, however required solely three stops. Right here, once more, we see a tradeoff. Barely decrease speeds can scale back the variety of charging breaks with out including a lot to the clock. However every car is completely different, and as one commenter well famous,
“Every car may have its personal optimum velocity.”
It’s not about velocity for velocity’s sake; it’s about understanding how your EV behaves on lengthy hauls.
Why the Kia EV6’s 800V Structure Revolutionizes Lengthy-Distance Journey
Nonetheless, there are real-world variables that complicate these theoretical positive aspects. As u/s6511 identified,
“There’s a little bit of threat with an EV charger being in use, partly operational, or not operational.”
Even Tesla house owners have often discovered themselves in tough conditions when charging stations had been unavailable or beneath restore.
One consumer recalled being stranded as a result of the one accessible Supercharger in vary was offline, leaving them to look at a working charger they couldn’t use. These hiccups remind us that even when a quicker tempo works on paper, execution relies upon closely on infrastructure reliability.
Key EV Charging Cease Methods for Environment friendly Highway Journeys
In that context, the Kia EV6 stands out. It’s one of many few EVs that may make this time-vs-speed dialogue significant due to its 800-volt structure and high-speed charging functionality, typically topping 200 kW in splendid situations. Kia claims it could cost from 10% to 80% in round 18 minutes, and impartial testing has proven that this efficiency is constant. With that sort of velocity, the penalty for stopping turns into much less of a burden, and journey planning turns into extra versatile.
That stated, the price of effectivity remains to be actual. The Reddit consumer’s quicker 80 mph journey burned via 50 kWh greater than the 65 mph run in most public charging networks, which interprets to about $20. For some, that’s a straightforward trade-off for an hour saved.
For others, notably these with tighter budgets or entry to cheaper dwelling charging, it may not be value it. The important thing takeaway isn’t that one strategy is healthier, it’s that you simply now have the choice to tailor your technique based mostly on the capabilities of your car and your journey targets.
2025 Kia EV6 Specs: Battery, Value, and Efficiency Highlights
- The refreshed 2025 EV6 affords upgraded battery choices, 63 kWh for traditional fashions and as much as 84 kWh for long-range trims. Kia claims the rear‑wheel-drive lengthy‑vary model now achieves round 319 miles per cost
- U.S. costs begin round $42,900 for the bottom Mild RWD, rising to roughly $63,800 for the GT efficiency variant, plus a vacation spot charge (~$1,475)
- Constructed on the E‑GMP structure (shared with the Ioniq 5), the EV6 helps DC fast-charging at as much as 240 kW and electrical outputs starting from ~125 kW in entry trims to as a lot as 430 kW (roughly 576 hp) within the GT
- Its primary rivals embody the Hyundai Ioniq 5, Chevy Bolt EUV, Ford Mustang Mach‑E, Tesla Mannequin Y, Volkswagen ID 4, and luxurious fashions just like the Volvo EX40/C40 and Mercedes EQA. The EV6 typically stands out for superior cost velocity, vary, and driving dynamics
However let’s not get forward of ourselves. As mmiggs commented, even beneath splendid situations, the distinction in complete journey time might be modest, typically simply 12 minutes over a full day of driving.
And as additionally they famous, EVs nonetheless path gasoline automobiles with regards to general journey velocity, particularly when infrastructure is inconsistent. In a single instance, an EV driver arrived greater than two hours behind their sibling driving an ICE car over the identical route.
The rising information means that conventional driving habits may have some rethinking within the EV period. Slower speeds could protect vary, however they don’t at all times protect time. And for automobiles just like the Kia EV6, with a robust charging curve and real-world effectivity, it could typically be extra sensible, not essentially smarter or safer, to drive at average freeway speeds and reap the benefits of speedy charging alongside the way in which.
Will this transformation the way in which you drive your EV? At what speeds is your automobile best?
