The new Prius AWD-e system will certainly deliver added traction and confidence for drivers but, in true Prius fashion, the 2019 AWD-e will lay claim to being one of the most fuel efficient all-wheel-drive-equipped passenger cars available in the U.S. Toyota estimates that the AWD-emodel could account for as much as 25% of annual U.S. Prius sales.
 
Toyota's AWD-e system is ideal for Prius. The automatic on-demand system does not require a center differential or other torque-apportioning device, nor does it need a front-to-rear driveshaft. Instead, the 'e' in AWD-e stands for electric.

The Prius AWD-e uses an independent electric, magnet-less rear motor (a Toyota first) to power the rear wheels from 0 to 10km/h, then when needed, up to 70km/h. This system provides the power to the rear wheels to pull away from a stop, yet the on-demand system recognises when all-wheel drive performance is not needed to provide great fuel economy.
 
The addition of the available AWD-e system is only part of the wider revision to the 2019 Prius, which debuts newly refined front and rear exterior styling, along with additional interior updates. Let’s not forget the front-wheel drive Prius will still offer the impressive fuel economy for which it is known
 
The AWD-e models use a newly developed compact Nickel Metal Hydride battery that is designed to provide excellent performance in cold-weather conditions. The AWD-e battery fits under the rear seat area and does not impact the luggage capacity. The FWD models will tout a lithium-ion battery.
 
The Prius AWD-e models offer the same carrying space with the standard 60:40 split rear seatbacks lowered as other Prius models. That's more than in some small SUVs and larger than most full-size sedans. Expanding carrying options, the Prius AWD-e will offer available Genuine Toyota Accessory cargo crossbars for roof rack attachments, such as for carrying bikes, kayaks, snowboards, or a cargo carrier.
