Its Round 2 in the Norwegian Tesla owner versus Tesla fight over claims of false advertising, with a new lawsuit reported this week.

Reported by Dagens Næringsliv, a Norwegian news outlet, a group of 79 Model S P85D owners have filed a lawsuit against Tesla, alleging that Tesla overstated its Model S performance numbers. According to the owners, the Model S hits 469-horsepower, not 691-horsepower as Tesla claims.

At the crux of the dispute are differing thoughts on how power output should be communicated in marketing material. Tesla adds both front and rear outputs (at 221-horsepower and 469-horsepower, respectively) to reach a final figure, whereas the owners read 469-horsepower when running it against a dynamometer.

In Sept. 2016, a similar lawsuit saw an out-of-court settlement of $7,700 awarded to each of 126 Model S P85D owners, with the option to accept a combination of a smaller payment plus upgrades. This lawsuit saw its owners make similar claims. The Model S P85D is no longer on sale in Norway, but it is unclear if the lawsuit was the direct result of that decision.

In a statement to Dagens Næringsliv, Christoffer Falkeid, the plaintiff’s lawyer, said “it’s the same kind of case that ended up in a compromise the last time. It’s about the power of the car and the mistakes in marketing and in the sales process, but I do not want to go into amounts.”

To date, Norway has been an avid enforcer of reduced emissions on the world stage. It has pledged to eliminate the sale of gas vehicles by 2025. Also, sales of electric and hybrid cars have outsold gas-powered cars for the first time in all of 2017, in part due to government subsidies and tax incentives, along with a stronger national charging station network, road toll exemptions, and car-pooling perks. Now, even large corporations are stepping into the mix with Norwegian firms ASKO and postal service Posten Norge reserving some Tesla Semis.

The trial takes place in June at the Oslo District Court. However, Tesla may opt to reach a settlement before then.
