The number of plug-in hybrid cars has expanded greatly over the past few years.
If you've had trouble keeping track of all of these new plug-in cars, fear not.
A couple of weeks ago, we gathered the relevant data for every battery-electric car on sale today, and presented it to you in one place.
Now we've done the same for plug-in hybrids, which combine battery and engine power into a hybrid vehicle that can run more than a conventional hybrid's usual mile or so on electricity alone.
Every vehicle here shows the manufacturer's suggested retail price, plus any mandatory destination and handling fees.
The prices don't include any local or federal tax incentives or rebates—so many cars here may be available cheaper, for those eligible for specific credits or rebates.
Efficiency figures are rendered in Miles Per Gallon Equivalent, or MPGe, a measure of how far a car can travel electrically on the same amount of energy as contained in 1 gallon of gasoline.

2017 Audi A3 e-tron Sportback
8.8 kwh battery, 16 miles (EPA), 83 MPGe, 75 kw motor (204 hp combined)
The long-awaited A3 e-tron is the first production Audi plug-in hybrid sold in the U.S. It's also the only way to get an A3 hatchback on this side of the Atlantic, and its restrained styling is perfect for those who don't want to attract too much attention to themselves.
2017 BMW 330e i Performance2017 BMW 330e iPerformance - $44,795
2017 BMW 330e i Performance
7.6 kwh battery, 14 miles (EPA), 71 MPGe, 56 kw motor (248 hp combined)
The BMW 330e is a plug-in hybrid version of the German luxury automaker's best-selling 3-Series sedan. It's one of a growing number of BMW plug-in hybrids based on existing models that wear the "iPerformance" label, an effort to tie them to the i3 and i8 dedicated plug-in cars.
2017 BMW 740e xDrive i Performance2017 BMW 740e xDrive iPerformance - $90,095
2017 BMW 740e xDrive i Performance
9.2 kwh battery, 14 miles (EPA), 64 MPGe, 82 kw motor (322 hp combined)
The 740e is based on BMW's 7-Series full-size luxury-sedan flagship. Despite its considerable size, it achieves an EPA-rated 14 miles of electric range. Like other 7-Series models, the 740e features a "Carbon Core" chassis that incorporates carbon fiber-reinforced plastic, aluminum, and high strength steel to cut weight.
2017 BMW i82017 BMW i8 - $141,695
2017 BMW i8
7.1 kwh battery, 15 miles (EPA), 76 MPGe, 96 kw motor (357 hp combined)
The BMW i8 is unlike virtually any other plug-in hybrid on sale today. It's a sexy, low-slung coupe with an emphasis on sporty driving. While it is an expensive and low-volume model, the i8 is likely beneficial to the image of green cars. A mid-cycle refresh of the i8 is expected sometime this year, with a convertible model following sometime after that.
2017 BMW X52017 BMW X5 xDrive 40e - $63,095
2017 BMW X5
9.0 kwh battery, 14 miles (EPA), 56 MPGe, 82 kw motor (308 hp combined)
BMW's plug-in hybrid SUV marks the beginning of a barrage of new plug-in models from the German luxury brands. The fifth plug-in vehicle from BMW, it competes in a growing segment that includes plug-in hybrid luxury SUVs from Volvo, Mercedes-Benz, and Porsche.
2017 Chevrolet Volt2017 Chevrolet Volt - $34,095
2017 Chevrolet Volt
18.4 kwh battery, 53 miles (EPA), 106 MPGe, 111 kw motor
In its second year following a major redesign, the Volt gains more available features but otherwise remains pretty much unchanged. Debuting as a 2016 model, the second-generation Volt features numerous improvements over its predecessor, including a larger, 18.4-kwh battery pack that affords a 53-mile electric range, as well as less-controversial styling.
2017 Chrysler Pacifica Hybrid2017 Chrysler Pacifica Hybrid - $43,090
2017 Chrysler Pacifica Hybrid
16.0 kwh battery, 33 miles (EPA), 84 MPGe, 63 kw and 85 kw motors, (260 hp combined)
The Pacifica Hybrid is both the first plug-in hybrid minivan, and the first plug-in hybrid from Fiat Chrysler Automobiles, whose CEO is notoriously critical of electrified vehicles. Its powertrain combines an Atkinson-cycle V-6 engine with an electric drive system with two motors. Both are capable of driving the Pacifica Hybrid's front wheels, but one motor is typically used as a generator.
2017 Ford C-Max Energi2017 Ford C-Max Energi - $27,995
2017 Ford C-Max Energi
7.6 kwh battery, 20 miles (EPA), 95 MPGe, 88 kw motor (195 hp combined)
Ford's plug-in hybrid tall wagon is getting somewhat long in the tooth, but it does offer a fairly practical package. The C-Max is actually sold in Europe with non-electrified powertrains, it is only offered in the U.S. as a hybrid or this Energi plug-in hybrid model.
2017 Ford Fusion Energi2017 Ford Fusion Energi - $31,995
2017 Ford Fusion Energi
7.6 kwh battery, 22 miles (EPA), 97 MPGe, 88 kw motor (195-hp combined)
The Ford Fusion Energi mid-size sedan shares its powertrain with the C-Max Energi, but for 2017 changes to its powertrain control software and regenerative braking algorithms yielded a slight boost in all-electric range. That range is now 22 miles, up from 20 before. The Fusion Energi also gets the same exterior and interior styling changes as the rest of the 2017 Fusion lineup.
2017 Hyundai Sonata Plug-In Hybrid2017 Hyundai Sonata Plug-In Hybrid - $35,435
2017 Hyundai Sonata Plug-In Hybrid
9.8 kwh battery, 27 miles (EPA), 99 MPGe, 50 kw motor (202 hp combined)
Like Ford, Hyundai offers both hybrid and plug-in hybrid versions of its mid-size sedan. The Sonata Plug-In Hybrid is in most mechanical respects identical to the Sonata Hybrid, but uses a larger battery pack and a more powerful electric motor.
2017 Kia Optima Plug-In Hybrid2017 Kia Optima Plug-In Hybrid - $36,105
2017 Kia Optima Plug-In Hybrid
9.8 kwh battery, 29 miles (EPA), 103 MPGe, 50 kw motor (202 hp combined)
The Kia Optima Plug-in Hybrid is a virtual twin of the Sonata Plug-In Hybrid, sharing a powertrain and body shell with the Hyundai mid-size sedan. However, the Kia has slightly higher EPA electric range and efficiency ratings. That, along with different styling and a slightly higher base price, distinguishes the Optima from its Sonata sibling.
2017 Mercedes-Benz C350e2017 Mercedes-Benz C350e - $46,415
2017 Mercedes-Benz C350e
6.4 kwh battery, 11 miles (EPA), 51 MPGe, 60 kw motor (275 hp combined)
While BMW leads the German luxury brands in plug-in hybrids, Mercedes-Benz is catching up. Just as the standard C-Class competes against the BMW 3-Series, the C350e competes against BMW's 330e iPerformance model. But while the Mercedes boasts more power, it has a smaller battery pack, and trails the BMW in electric range and efficiency.
2017 Mercedes-Benz GLE550e 4Matic2017 Mercedes-Benz GLE550e 4Matic - $67,225
2017 Mercedes-Benz GLE550e 4Matic
8.8 kwh battery, 12 miles (EPA), 43 MPGe, 85 kw motor (436 hp combined)
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.
2017 Mercedes-Benz S550e2017 Mercedes-Benz S550e - $97,525.
2017 Mercedes-Benz S550e
8.0 kwh battery, 14 miles (EPA), 58 MPGe, 132 kw motor (436 hp combined)
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.
2017 Porsche Cayenne S E-Hybrid Platinum Edition2017 Porsche Cayenne S E-Hybrid - $79,750
2017 Porsche Cayenne S E-Hybrid Platinum Edition
10.8 kwh battery, 14 miles (EPA), 46 MPGe, 70 kw motor (416 hp combined)
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.
2017 Toyota Prius Prime Premium2017 Toyota Prius Prime - $27,985
2017 Toyota Prius Prime Premium
8.8 kwh battery, 25 miles (EPA), 133 MPGe, N/A motor (121 hp combined)
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.
2017 Volvo XC90 Excellence2017 Volvo XC90 T8 "Twin Engine" - $68,795
2017 Volvo XC90 Excellence
9.2 kwh battery, 14 miles (EPA), 54 MPGe, 60 kw motor (315 hp combined)
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.
2017 Cadillac CT6 Plug-In Hybrid
2017 Cadillac CT6 Plug-In Hybrid
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.
