Mercedes’ upcoming electric CLA has a ton of neat EV tech and options
Mercedes released a look at the powertrain technology of its upcoming electric CLA, and it includes tons of neat EV tech and some interesting options for battery technology and what looks to be the most flexible charging system we’ve seen yet.
We’ve already learned a fair amount about the CLA after first seeing the concept last year, and Mercedes released a few new specifics today regarding its powertrain.
In keeping with previous information we knew, the CLA is targeting extremely high efficiency of 12kWh/100km, which translates to just 193Wh/mi or 5.2mi/kWh. That’s more efficient than anything else on the road today – with Lucid’s Air Pure reaching 200Wh/mi, or 5mi/kWh. And just less than what Tesla is claiming the Cybercab will be capable of, at 5.5kWh/mi.
This is thanks to Mercedes’ new compact EDU 2.0 electric motor, which is part of its new Mercedes Modular Architecture (MMA) which will underpin its upcoming electric vehicles. The drive motor will be 200kW on the rear axle, though all-wheel drive models will be available with an additional 80kW unit on the front axle. A two-speed transmission will ensure efficiency at high speeds and low.
For more efficiency in cold weather, the CLA will use an air-to-air heat pump which is able to capture heat from the motor, battery, and ambient air to heat the cabin. While batteries and motors don’t make nearly as much waste heat as inefficient ICE engines, it’s still good to be able to channel heat to wherever you need it.
Mercedes says that the CLA will come equipped with a choice of two different batteries, each with different chemistries.
The larger 85kWh model will be capable of an unnecessarily-high 750km (466mi) of WLTP range – though WLTP numbers are always higher than EPA numbers, so expect something in the high-300s in EPA parlance. This battery will add silicon oxide to the anode for higher energy density, a technology that has been pioneered by Sila Nanotechnologies, a company which Mercedes is a lead investor in.
The smaller battery will be 58kWh, and will use lithium iron phosphate (LFP) chemistry. LFP is a cheaper but lower energy density technology, with higher long-term durability and simpler sourcing of minerals (it uses no cobalt, whereas Mercedes says cobalt has been “reduced” in the larger batteries). However, LFP generally has slower fast charging and cold weather performance.
On charging: the “premium” battery will have an 800V configuration capable of up to 320kW charging speeds. Mercedes says this can add 300km (186mi) of range in 10 minutes, and also says that the car will have a broad charging curve, which means you’ll get high charge rates even if the battery isn’t close to empty. It didn’t specify if the smaller LFP battery will have the same charge rate.
This high charging rate allowed Mercedes to set a record traveling 3,717km (2,309mi) in 24 hours at the Nardo test track in Italy in a pre-production CLA. That’s an average travel rate of 96mph – including time spent charging.
We also learned something about Mercedes’ NACS adoption plans. While just about everyone has committed to transitioning cars to NACS, it has taken longer than expected (largely due to Tesla’s chaotic CEO firing the whole supercharger team for little reason), and few cars have native NACS inlets yet. Some brands can already charge at Superchargers with adapters, but Mercedes is still on Tesla’s “coming soon” page.
As a result of delays in onbaording automakers, some seem to have pulled back on their plans, pushing NACS ports to later model years. But Mercedes has a new and unique solution – it will just put both CCS and NACS ports on the CLA, right on top of each other.
Mercedes says “in the future, new entry-level models will be capable of bidirectional charging,” but isn’t clear whether this model will be capable of that.
Electrek’s Take
While this is short of a full release of specs, we’re excited by what we see here. Mercedes seems to confirm that they’re meeting the efficiency goals they set out, and we like that they’re offering a variety of options and taking advantage of some newer EV tech like 800V charging infrastructure.
The inclusion of both NACS and CCS is very interesting, again offering options to owners during the transition. That seems to be the big message from Mercedes here – we’re not going to just pick one tool, we’re going to use all of them.
But pricing and availability are obviously big questions, as is design.
The concept looks fantastic, but concepts always change on their way into production. The shape of the camouflaged test vehicle is very different – but looks to have some shrouding on the front and back to hide its shape, so we’ll have to wait until we see this thing unveiled for more.
And as for pricing – Mercedes says the CLA will be an “entry-level” car, but who knows what that means anymore these days. The base ICE CLA starts at around $44k currently, so lets see if they can hit that number.

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.

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.
