Road-test data show some French electric SUVs still trail a 6-year-old Tesla Model Y on real-world range

Independent road tests are still putting several French electric SUVs behind Tesla’s Model Y on real-world efficiency—despite the Tesla being described as a six-year-old benchmark, according to figures highlighted by L’Automobile Magazine. The gap isn’t coming from lab-only ratings. It shows up in measured energy use in kWh per 100 kilometers on routes meant to mirror everyday driving, especially on non-highway roads.

That focus on efficiency matters because it largely determines how far an EV goes on a given battery size—and, by extension, how often drivers need to stop and how much they’ll pay for electricity. Comfort, features, and service networks still count, but for shoppers comparing “real range,” efficiency is often the deciding number.

The discussion has only intensified in 2026 as electric SUVs have become a core part of Europe’s car market, forcing automakers to balance price, profit margins, and performance that holds up under repeatable testing.

A key road figure: 21.5 kWh/100 km on secondary roads

L’Automobile Magazine points to a measured 21.5 kWh/100 km on a “route départementale” cycle—roughly the kind of secondary roads common outside major cities—during a recent test focused on the consumption and range of French electric SUVs. Those roads, typically around 45 to 55 mph (70–90 km/h), represent a big share of daily and suburban driving. They’re often more forgiving than highways, but they still expose aerodynamic drag and how steadily a vehicle can hold speed.

At that consumption level, range depends directly on usable battery capacity. As a rough example offered in the article, a 70 kWh net battery would translate to about 200 miles of theoretical range (325 km), before accounting for safety buffers, weather, terrain, and stops. The point isn’t that any one number “condemns” a vehicle—some models prioritize space, power, or larger wheels—but it quickly signals the efficiency level achieved in realistic conditions.

For French brands, the sensitive issue is what comes next: if road consumption is high, it’s hard to make up the difference without a larger battery. Bigger batteries raise price and weight—and can even push consumption higher—creating a technical loop that’s made efficiency a marker of industrial maturity alongside fast charging and software control.

In that context, the Model Y has become a yardstick because it combines family-SUV size with efficiency figures that often test well in independent trials. The perception gap grows when the reference vehicle is described as older, because many consumers expect newer generations to do better at similar prices. That turns a model-to-model comparison into a broader industrial and political debate.

Tests also emphasize that secondary roads can be revealing for heavy vehicles. Energy recuperation, inverter losses, and the ability to keep consumption stable around 55 mph (90 km/h) weigh heavily. Automakers that can’t hit those targets either need larger batteries or must accept shorter range.

Model Y testing shows range close to the smaller Model 3

In another test, L’Automobile Magazine reports that the Tesla Model Y delivers real-world range that’s nearly as strong as the Tesla Model 3—a notable result because the Model Y is taller, heavier, and less aerodynamic. The sharpest observation centers on secondary-road driving, where the SUV stands out most in the comparison presented, reinforcing the idea that efficiency isn’t only about shape. Powertrain design and software strategy matter, too.

The magazine also cites a comparison involving a Renault Zoé R110 to show how results can flip depending on where you drive. The smaller, lighter Zoé is said to do slightly better in city use—by 0.8 kWh/100 km—but falls behind on the road, where the French car is reported at 4.1 kWh/100 km worse. The reversal highlights that efficiency isn’t uniform: cars optimized for urban driving can lose more ground as steady speeds rise.

Technically, Tesla’s edge is often attributed to an integrated approach—motor, electronics, software, and thermal management working as a system. That doesn’t mean other automakers aren’t improving, but the gap becomes visible when comparisons focus on real consumption at steady speeds across varied road profiles. Details like tire choice, regenerative-braking calibration, inverter efficiency, and heating strategy—especially in winter—can move the needle.

Real-world numbers still depend on the test protocol: temperature, exact route, average speed, and payload. But the value of specialized outlets is repetition across many vehicles using stable methods, giving readers a hierarchy that can be more practical than regulatory certification cycles.

With the Model Y testing closer to an efficient sedan than many expect, pressure remains on French electric SUVs. Closing the gap, the reporting suggests, means improvements in aerodynamics, weight optimization, and HVAC efficiency. Every 1 kWh/100 km saved translates into more miles of range—or allows a smaller battery for the same range, which can also help price and weight.

Frandroid pushes back on Tesla’s “most efficient SUV” messaging

Tesla’s marketing around Model Y efficiency is also discussed by French tech outlet Frandroid, which argues the claim of “the most efficient SUV in the world” deserves nuance. The point, Frandroid says, isn’t to deny the vehicle’s strong results—but to clarify that outcomes vary by version and by reference standard, and that the most economical variant isn’t necessarily the one highlighted in marketing.

That distinction matters because consumption figures can change depending on the standard—WLTP in Europe versus EPA in the United States—and on whether charging losses are included. Energy measured at the plug can be noticeably higher than what a vehicle’s onboard computer reports. For drivers, that difference shows up in electricity bills and charging time, directly affecting operating costs.

Online comparison tables also cite broad benchmarks, including a WLTP consumption around 13.2 kWh/100 km for some variants, with higher values once charging losses are included. The takeaway: shoppers need to know what they’re comparing—standardized test-cycle consumption, real highway consumption, or total energy use including charging losses.

For French electric SUVs, that debate can cut both ways. Transparent, repeatable real-world measurements from specialized media can strengthen the discussion. By contrast, relying on a single headline number without clearly stating the protocol can weaken credibility as buyers increasingly verify claims against typical routes.

The result is competition on multiple fronts: efficiency, fast charging, consumption at 80 mph (130 km/h), and performance stability across temperatures. Tesla often scores well across several criteria, but rankings can shift with wheel size, tires, all-wheel drive, and trip type. A more nuanced view keeps the issue grounded in measurable indicators rather than slogans.

Two real-world range benchmarks: 280 miles mixed, about 205 miles on the highway

Measurements published in a “supertest” of the Tesla Model Y Propulsion offer simple reference points: a stated mixed-use range of 450 km (about 280 miles) and a long-distance highway range around 330 km (about 205 miles). Those benchmarks help explain why efficiency sits at the center of the debate: the gap between mixed driving and highway travel is large, and it dictates how often drivers stop on major routes.

For drivers, about 205 miles of highway range doesn’t mean repeating 205-mile legs every time. In practice, stops often happen between roughly 10% and 80% state of charge to maximize charging speed, which shortens each leg. A more efficient vehicle turns that constraint into an advantage by covering more miles within the same charging window and reducing reliance on the highest-power chargers.

Those figures also sharpen comparisons with French electric SUVs that test higher in kWh/100 km. With similar battery sizes, higher consumption mechanically reduces range, pushing drivers to accept more stops or buy a larger-battery version. Automakers can offset some of that with very strong fast-charging performance, but efficiency remains structural because it improves range in all conditions—including when chargers are busy or power-limited.

The issue also hits household budgets. A difference of a few kWh/100 km, multiplied over thousands of miles, becomes meaningful extra electricity cost—especially when charging on pricier fast-charging networks rather than at home. In that sense, efficiency has become an everyday consumption argument much like fuel economy in gas-powered vehicles.

For French brands, the challenge is twofold: improve efficiency without sacrificing interior space, while keeping costs under control. The reporting points to aerodynamics, weight reduction, power electronics, and software calibration as key levers. In 2026, the market signal is clear: buyers aren’t satisfied with a WLTP number alone—they want credible real-world range and consumption that matches the vehicle’s price positioning.

Questions frequently asked

Why does kWh/100 km matter so much for range? Because range depends on a simple relationship between usable battery capacity and consumption. If an SUV uses more energy, it travels fewer miles on the same battery and must recharge more often on long trips.

Why can an SUV use more energy on the road than in the city? In city driving, regenerative braking and lower speeds can limit energy use. On the road, steady speeds increase aerodynamic losses and reveal the efficiency of the powertrain.

WLTP, EPA, charging losses—what should drivers compare? For real-world use, independent measurements on typical routes (city, secondary roads, highway) are useful, along with clarity on whether charging losses are included. WLTP is a regulatory baseline but doesn’t always reflect highway gaps.

Can faster charging make up for higher consumption? Partly. Higher charging power can reduce stop time, but higher consumption increases the energy that must be added. Efficiency remains a constant advantage, especially when chargers are limited or expensive.
