Mercedes-Benz S580e Plug-In Quietly Revealed In Europe With 510 HP

The 2021 Mercedes-Benz S-Class fell earlier today, with the first two models in the new lineup – the S500 and S580 – both featuring mild hybrid powertrains featuring EQ Boost technology. But already Mercedes-Benz has revealed the third option of the new S-Class range abroad: the plug-in hybrid.

Dubbed the S580e, the S-Class plug-in hybrid uses the same turbocharged 3.0-liter inline-six gasoline engine as the base S500. But here it adds an electric motor mounted on the gearbox and a 28-kilowatt-hour battery for a combined total power of 510 horsepower (380 kilowatts). That’s an 81 hp (60 kW) improvement over the S500 and 41 (31 kW) more than the standard S580.

But of course, the S580e is all about electric range – and on the European WLTP test cycle, the S-Class plug-in can drive up to 62 miles (100 kilometers) on battery alone. That’s more than double the range of the previous S650e on the same WLTP scale. Considering that the battery of the new S580e is more than twice as large as that of the outgoing S650e – 28.0 kWh vs. 13.5 kWh – this new range is expected.

For now, the Mercedes-Benz S580e is only intended for Europe. But the S-Class plug-in will probably arrive in the United States in the near future, our best guess is officially next year. But when the S580e makes its way to the United States, don’t expect the European model’s 100 kilometers of electric driving to be prolonged; on the EPA scale, that number could drop by about 20 to 30 percent.

The Mercedes-Benz S500 and S580 will be the first two versions of the S-Class available in the United States, both going on sale in early 2021. As mentioned, the base S500 gets a 429 inline-six turbocharged engine. hp (320 kW) and 384 lb-ft (521 Newton-meters), while the more powerful S580 model uses a twin-turbocharged V8 to produce 469 hp (350 kW) and 516 lb-ft (700 nm). Pricing details for these two models will be available closer to their on-sale date.
