2018 Toyota Prius Prime Trims Comparison

All Prius Primes have a 1.8-liter four-cylinder engine paired to a plug-in hybrid system. Total system output is 121 horsepower, which drives the front wheels through a specialized continuously variable automatic transmission. The EPA estimates the Prime can drive up to 25 miles using pure electric power. Fully charging the battery takes 5 hours and 30 minutes using a 120-volt power source or a little more than 2 hours with 240 volts.

The Plus trim level starts you out with 15-inch wheels, LED headlights, automatic climate control, keyless access (driver's door only) and start, heated front seats, a 7-inch touchscreen, Bluetooth, a USB port, and a six-speaker sound system with satellite radio. A suite of driver safety aids, called Toyota Safety Sense P, is also standard and includes adaptive cruise control, forward collision warning with automatic emergency braking, lane departure warning and lane keeping assist, and automatic high beams.

Stepping up one rung to the Premium trim level puts you into the Prius Prime's sweet spot. It includes a power driver's seat, an 11.6-inch central touchscreen and upgraded infotainment system, simulated leather (SofTex) upholstery, keyless entry on the other three doors, satellite radio and wireless smartphone charging.

The Advanced trim level adds on a premium audio system, blind-spot monitoring with rear cross-traffic alert, a heated steering wheel, an auto-dimming mirror, a head-up display, a smartphone app with a charge management system and remote-control climate operation, automatic wipers and a semiautomated parking function.
