2018 Toyota Prius: Still Frugal After All These Years
The 2018 Toyota Prius “Remains A Hybrid Benchmark,” Toyota is quick to remind us. This is not just marketing puffery or corporate bragging. The little guys are amazingly fuel efficient, and since they were pretty much the first to market, they’re the yardstick against which other hybrids are judged.

There’s shift-by-wire tech to select, er, “gears” via the dash-mounted shifter. Regenerative braking recovers kinetic energy, turns it into electrical power, and stores it in the battery pack. In this, the fourth-gen Prius, the hybrid components are smaller and lighter than before. The battery is now a lithium-ion unit, replacing the outgoing nickel-metal hydride battery, and is small enough to fit under the rear seat. The 2ZR-FXE 1.8-liter engine is more than 40 percent thermal efficient and quieter than the previous gen?s plant.
