The fifth-generation Toyota Prius is debuting in Europe several hours before the new model premieres in the United States. We don't know what specs or features to expect yet, but this unveiling shows at least some of what's to come.

In Europe, the new Prius is only available as a plug-in hybrid. The powertrain includes a 2.0-liter four-cylinder engine with a total system output of 220 horsepower. This is a 99-hp (74-kW) improvement over the current vehicle's electrically assisted 1.8-liter four-pot that makes 121 hp

Toyota has confirmed that the Prius Plug-In in Europe will have a much larger battery than before. The new unit is situated under the rear seats and offers a 50% longer range than its predecessor. The price for this model is still unknown.

The Prius plug-in will be available with an optional solar roof panel. The European-market model announcement doesn't mention whether this system would improve the vehicle's driving range.

Already familiar to drivers and pedestrians alike, the Prius's design has been updated and it now looks sleeker than ever. The roof's apex is pushed back to give it a sleek coupe-like appearance. The design changes seem to be mostly centered on height and wheelbase, with the overall size being shorter by a couple of inches. Width has been increased which might be beneficial to owners of lower trucks.
