The 2017 Hyundai Ioniq will debut at the Geneva Motor Show next week, with the full global lineup--hybrid, plug-in hybrid, and battery-electric versions--in attendance.

Ahead of that event's media days, the company has released some additional specifications on the three vehicles.

For one thing, they'll be known (at least in Europe) as Ioniq Hybrid, Ioniq Electric, and Ioniq Plug-In.

The Ioniq is a dedicated model, meaning there's no gasoline-only equivalent, and it rides on underpinnings adapted from those of the 2017 Hyundai Elantra.

And it's the first vehicle offered with all three powertrains by a major global maker. The first to hit showrooms will be the Ioniq Hybrid.

The company has said it hopes to get a rating of 50 mpg or better from the EPA, which would equal the last generation of Toyota Prius--and it says it expects a better highway rating than the Prius due to the different architecture of its single-motor hybrid system.

The hybrid model uses a direct-injected 1.6-liter four-cylinder gasoline engine with an output of 104 horsepower mated to a six-speed dual-clutch transmission, teamed with a single 32-kilowatt (43-hp) electric motor and a lithium-ion batttery pack of unspecified size.

Hyundai says the combined output of the Ioniq Hybrid's engine and motor is 139 hp, and it will have a top speed of 115 miles per hour.

It stresses that the driving experience will be "more dynamic" than other hybrids--a criticism easily leveled at the previous Prius but less so at the new and considerably improved 2016 model.

The Ioniq Electric will be powered by an 88-kw (120-hp) electric motor, with a top speed of around 100 miles per hour.

Energy is stored in a 28-kilowatt-hour lithium-ion battery pack, giving a quoted range of 155 miles, presumably on either the European or Korean test cycle.

That number could produce an EPA-rated range of anywhere from 110 to 140 miles on the U.S. test cycle.

Finally, the Ioniq Plug-In (which Hyundai says will be the last to arrive in North America) will use an 8.9-kWh battery that gives it a range of about 30 miles, again on European or Korean test cycles.

That might work out to perhaps 22 to 26 miles of rated range in the U.S.

Its electric-motor output falls between those of the Hybrid and the Electric, at 45 kw (60 hp), and it uses the same 1.6-liter engine and six-speed dual-clutch transmission as the Ioniq Hybrid.

For the U.S., we'd expect the first Ioniq cars to arrive at dealers in the first quarter of 2017, with the Ioniq EV likely arriving in California and a few other states before the national rollout Hyundai promised.

The ambitious carmaker has said it expects to sell 77,000 Ioniq Hybrids globally during the car's first year on the market.
