This Yaris five-door is powered by, not surprisingly, a hybrid drivetrain. The star of this under-hood show is a 1.5-liter gasoline four-cylinder that produces around 73 horsepower and roughly 82 lb-ft of torque. The internal-combustion engine is paired to a continuously variable transmission as well as an electric motor. A nickel-metal hydride battery pack stores and releases electrons as required. Naturally a bunch of other electronic parts are included as well. System output totals a rather meager 100 ponies.
