No niinhän osa autoista pääsikin WLTP:tä pitemmälle, siis kesätestissä. Kesäkelissähän WLTP mitataan.
Ja tuossa Fraatin linkaamassa jutussa kirjoitettiin vuosikymmen sitten tehdystä range kaunistelusta. Ei tätä päivää.
Eikös tuossa ole ihan tuoreettakin matskua?
Data collected in 2022 and 2023 from more than 8,000 Teslas by Recurrent, a Seattle-based EV analytics company, showed that the cars’ dashboard range meters didn’t change their estimates to reflect hot or cold outside temperatures, which can greatly reduce range.
Recurrent found that Tesla’s four models almost always calculated that they could travel more than 90% of their advertised EPA range estimates regardless of external temperatures. Scott Case, Recurrent’s chief executive, told Reuters that Tesla’s range meters also ignore many other conditions affecting driving distance.
Recurrent tested other automakers’ in-dash range meters – including the Ford Mustang Mach-E, the Chevrolet Bolt and the Hyundai Kona – and found them to be more accurate. The Kona’s range meter generally underestimated the distance the car could travel, the tests showed. Recurrent conducted the study with the help of a National Science Foundation grant.
Tesla, Case said, has consistently designed the range meters in its cars to deliver aggressive rather than conservative estimates: “That’s where Tesla has taken a different path from most other automakers.”
Failed tests and false advertising
Tesla isn’t the only automaker with cars that don’t regularly achieve their advertised ranges.
One of the experts, Gregory Pannone, co-authored a study of 21 different brands of electric vehicles, published in April by SAE International, an engineering organization. The research found that, on average, the cars fell short of their advertised ranges by 12.5% in highway driving.
The study did not name the brands tested, but Pannone told Reuters that three Tesla models posted the worst performance, falling short of their advertised ranges by an average of 26%.
About a decade ago, Tesla rigged the dashboard readouts in its electric cars to provide “rosy” projections of how far owners can drive before needing to recharge, a source told Reuters.
