With much of the US sweltering under a record-breaking heat dome, many EV buyers and owners are left wondering how their favorite electric cars perform in extreme summer temperatures. A new study tracking over 29,700 electric cars in real-world conditions provides the answers, and we’re sharing them here: these are the EVs that handle the summer heat best.

The EV leasing and subscription specialists Recurrent Auto have had tens of thousands of new and used EVs in their database over the years, giving them a massive dataset to analyze and draw conclusions from. So when they published their findings about which EVs had the best range in 90- and 100-degree weather, it was required reading for any would-be EV expert.

“Most of the country has a heat advisory right now, so we’re fielding lots of questions about EV batteries in extreme heat,” reads the intro to the Recurrent report. “Here’s the deal … electric cars work perfectly fine in hot weather. Range loss at 90F (32C) is minimal. Less than 5% change.”

Like many real-world aspects of EV ownership and longevity, that seems a lot better than what most people – or even most analysts would likely tell you. So, what gives?

“When temperatures pass 100F (37C), range impacts can be 17-18%,” they continue, “but these reductions are temporary while the AC is working to keep passengers cool … we advise that owners and dealerships avoid letting an EV sit with extremely low states of charge in this heat. An EV uses its battery power to keep the battery cool.”

The infographic

Recurrent’s findings put the Audi e-tron in the top spot, followed closely by recent JD Power favorites BMW i4 and Rivian R1S, all of which reportedly lose less than 3% of their range, even at an absolutely blistering 100°F.

To put those percentages into some easier to digest numbers (and fix the fact that Recurrent’s infographic makes it look, to my eyes, like you can’t drive a Nissan Ariya or Chevy Blazer at 100+ degrees), I’ve done the math, starting with the EV’s EPA-rated range under “ideal” conditions, then translated that using the percentages from Recurrent.

Would I bet my family’s safety and convenience on this rough-and-tumble chart while planning my next road trip? Absolutely not – go download Chargeway for that. Would I do the math because it’s a fun mental exercise that’s going to generate fun comments? Absolutely.

And finally…

Time-of-use electricity plans are hardly a new concept, but what makes Octopus Energy’s new time-of-use plan, OctopusFlex, great is that it’s ridiculously simple.

It rewards its customers in Lubbock, Texas, for using power between 10 pm and 6 am with cheaper rates, when the grid is quieter and cleaner. That means big savings for choosing to run your dishwasher or washer and dryer at night or charging your EV while you sleep.

And if customers use EV charger apps and smart thermostats, OctopusFlex automatically shifts electricity use to off-peak hours, which makes a real difference in accessing lower rates and saving money.

“This is about more than off-peak discounts,” said Nick Chaset, CEO of Octopus Energy US. “We’re giving customers the power to save money while actively supporting a cleaner, more balanced grid.”

Built around customer feedback, OctopusFlex is designed for total transparency. Customers can see exactly how and when they’re using electricity, what it’s costing them, and no connected devices are required. All they have to do is remember that electricity is cheaper from 10 pm to 6am.

“We’re thrilled to launch OctopusFlex, a plan our customers asked for and helped name,” said Katie Rosario, marketing manager. “With OctopusFlex, customers can shift energy use on their terms to save money.”

And in the summer, when solar power is strong and demand shifts, OctopusFlex customers could see low rates not just overnight, but all day long. (This program is designed for folks who don’t have solar and battery storage.)

“Time-of-use is one of the easiest ways to cut energy bills and reward flexibility,” said Daniel Kirwin, product manager. “We couldn’t be more excited to bring this to Texas.”

By nudging demand to off-peak hours, OctopusFlex helps reduce the strain on Texas’ grid during scorching summer afternoons, cuts the risk of blackouts, and makes room for more renewable energy.

Want to make the most of it? Pre-cool your home in the early morning, run big appliances overnight, charge your EV after 10 pm, and use smart plugs or timers to set and forget.

OctopusFlex is now live in Lubbock, Texas, where Octopus Energy became a retail provider in early 2024. Octopus Energy launched in 2016 and entered the US market in 2020. The company is part of Octopus Group, a global certified BCorp operating in 18 countries.
