Real-World Efficiency: Testing 55 Electric Vehicles to Find the True Range Leaders

The British outlet recently published results from 55 electric cars run through a new "everyday" efficiency schedule designed to reflect how most people actually drive — stop-and-go at neighborhood speeds rather than a flat 70 mph motorway cruise. That distinction matters because efficiency, more than any other spec, determines what you'll pay at the plug.

The "everyday" test, explained

Standard lab efficiency runs skew toward steady highway cruising, which undersells how much EVs benefit from slower speeds and regenerative braking. Autocar's new schedule strings together four laps of Horiba MIRA's "Number Two" circuit — a roughly 2.2-mile equilateral triangle — at 20, 30, 40, and 50 mph, with two full stops per lap to capture regen. The trip computer resets before each run, and the cars accumulate hundreds of additional miles in normal driving between sessions so editors can sanity-check the readings. Only one of the 55 cars — the 2,013-horsepower Lotus Evija — posted a worse everyday result than its touring result.

The 5.0 mpkWh club — and the one car that broke six

Nine cars cleared 5.0 miles per kilowatt-hour in the everyday run, a meaningful barometer for real-world efficiency:

• Renault 5 and Hyundai Inster — just over the 5.0 line
• Honda Super-N and BYD Dolphin Surf — 5.6 mpkWh each
• Renault 4 E-Tech — 5.6 mpkWh, impressive for its extra bulk
• MG 4 EV Urban — 5.5 mpkWh
• Ford Puma Gen-E — 6.2 mpkWh, the only car yet to breach six

What this means at the dealership

Two practical takeaways. First, small and light generally means efficient, but packaging and tuning matter just as much — the Renault 4 E-Tech and Ford Puma Gen-E are the proof. Second, focus on the car that sips less per mile at the speeds you actually drive, not just the headline range figure on the window sticker. That single number drives your home charging bill, your next road trip's stop count, and any tax-rebate math you're working through.

A US-shopper reality check: Renault 5, Renault 4, MG 4, and Honda Super-N aren't sold stateside, so this list functions as a methodology bellwether rather than a direct shopping list. The same physics apply to whatever is on your local lot, though. Efficiency is where the out-the-door savings live, week after week.
