The entry-level 2009 Toyota Prius Base trim remains unchanged from 2008, since the Prius will receive a major redesign for 2010. The 2009 Prius Base trim represents the most economical of the three Prius trims, although it still offers full power features, Bluetooth wireless connectivity for mobile devices, and a six-speaker AM/FM audio system with a CD player. Other standard interior features include air conditioning, remote keyless entry, and push-button start. Dual gloveboxes, a front center console, 60/40 split rear seats, and underfloor compartments also come standard. Outside, the Prius Base comes equipped with such features as a chrome-finish grille, halogen headlights with auto-off, and 15-inch wheels.
The Prius Base trim's hybrid powerplant consists of a 76-hp, 1.5-liter inline four-cylinder gas engine mated to two electric motors, which put out an additional 67 hp and 295 lb-ft of low-end torque. The hybrid engine pushes the Prius from 0 to 60 in an unspectacular 10.5 seconds, although fast acceleration isn't the goal here. Instead, most owners focus on fuel economy, and the Prius Base delivers outstanding numbers of 48/45 mpg. The hybrid engine links to an ECVT, or electronic continuously variable transmission, which provides smooth and seamless shifting. In addition, the hybrid engine virtually eliminates the "shift shock" between the gas and electric engines, which some hybrid engines display. The front-wheel-drive Prius Base rides on a MacPherson strut suspension and comes with such standard features as electric-assist power rack-and-pinion steering, four-wheel antilock brakes with electronic brakeforce distribution, traction control, and dual front-side and side curtain airbags for both rows. Owners can add stability control as an option.
