Along with the C350e and S550e sedans, the GLE550e is part of Mercedes' first wave of plug-in hybrids. It also contributes to the trend of large luxury plug-in hybrid SUVs, joining offerings from BMW, Volvo, and Porsche.

The Mercedes-Benz S550e is a plug-in hybrid version of the company's flagship luxury sedan. It would seem to offer the best of both worlds, but in reality the S550e is likely more focused on luxury and performance than outright fuel efficiency. A wireless-charging system will be offered as part of an upcoming refresh, although U.S. availability has not been confirmed.

While several other luxury brands now offer plug-in hybrid SUVs, Porsche was the first. It introduced the Cayenne S E-Hybrid for the 2015 model year, getting a head start on BMW, Mercedes-Benz, and Volvo. However, the Cayenne's emphasis on performance may not make it the greenest car in the real world.

While the previous-generation Prius Plug-In Hybrid flew under the radar for the most part, the current Prius Prime is a more fully-realized plug-in hybrid. It boasts model-specific styling, and more electric range than the previous model. It is also less eager to switch on its gasoline engine than the old Prius Plug-In Hybrid, allowing the driver to make the most of its electric-driving capabilities.

The XC90 is the only seven-seat plug-in hybrid available, and one of an emerging breed of luxury plug-in SUVs. It uses a turbocharged and supercharged 4-cylinder engine from Volvo's "Drive-E" line, working with an 8-speed automatic transmission and electric motor. An optional "Polestar Performance Optimization" tuning package boosts total system output to 421 hp, making this plug-in hybrid the most powerful Volvo ever.

A few plug-in hybrids have been left off this list for one reason or another.
We are awaiting final pricing, efficiency, or range ratings for a handful of models, although manufacturers have in some cases published unofficial estimates. That list of models includes the 2018 BMW 530e iPerformance, 2017 Cadillac CT6 Plug-In Hybrid, 2017 Hyundai Ioniq Plug-In Hybrid, and 2018 Porsche Panamera 4 E-Hybrid.
The 2014 and 2016 Cadillac ELR, a luxury coupe based on the first-generation Chevrolet Volt, has been discontinued, as has the 2014-2015 Honda Accord Plug-In Hybrid.
Additional models are expected to enter the U.S. market further down the line.
Plug-in hybrid versions of the Volvo S90 sedan and V90 wagon may be offered in the U.S., using the same T8 "Twin Engine" powertrain as the XC90.
A plug-in hybrid version of the Honda Clarity sedan will launch later this year, likely as a 2018 model, joining battery-electric and hydrogen fuel-cell versions.
