The Mercedes S580e is the daddy of PHEVs thanks to its incredible 62-mile electric driving range. And with a total system output of 496 hp (503 PS) and 553 lb-ft (750 Nm) of torque, it’s also a rapid means of jumping between stoplights on the way to your next global merger.

But merging that power with the road surface to generate forward movement isn’t always as easy as you’d want, as I discovered when I drove it in Germany last year. The PHEV was only available in rear-wheel drive form from launch, while the V8-powered S580 came exclusively with 4Matic all-wheel drive despite a 37 lb-ft weaker torque output.

The two-wheel drive car is fine for sunny climates, but everyone else is sure to welcome the news that Mercedes has now added an all-wheel drive option to the PHEV model. Bar the extra transmission hardware, the running gear is unchanged. Contrary to what the badge suggests, the PHEV isn’t powered by the S580’s V8, but a 362 hp (367 PS) 3.0-liter turbo six that’s augmented by a 148 hp (150 PS) electric motor.

The battery can be fully charged in as little as 30 minutes and can whisk the S580e along at speeds up of to 87 mph, though if you try that for any sustained period you’re not going to get near the 62-mile EV range. U.S. prices and mileage figures are still TBC, but in Germany, where both standard and long-wheelbase versions are available, the 4Matic starts at €130,638 ($147,900), compared with €126,830 ($143,600) for the two-wheel drive car.

Other changes that affect all S-class models include a tweaked MBUX infotainment system that now has the same zero layer philosophy already showcased on the EQS electric sedan. The idea is that the car will know which applications the driver needs based on the driving situation to save him from having to endlessly scroll looking for it, or giving voice commands. In addition, the main functions will always be visible on the top level of the screen. Which sounds suspicuously similar to what it was like in the old days when we still had actual hard buttons to press and didn’t have to go hunting in screen menus.

There are also more personalisation options available through Merc’s new Manufaktur program and, for the first time, a leather-free interior. Instead of cow, you get Benz’s Artico man-made leather. Yep, you can have your $150k Mercedes with plastic seats.
