Toyota Prius: Best Engineered Car of 2001

Following the Japanese introduction of the first-generation Prius in 1997, the significantly re-engineered second-generation model features new technology to meet the demands of the Western market, including improved driving performance, lower emissions, and reduced costs.

The readers and editors of Automotive Engineering International have selected the hybrid-electric Toyota Prius as the world's best engineered passenger car from the crop of new 2001 models. After studying reader response, the significantly re-engineered car was selected by the editors because it seats four to five people and their luggage, is one of the most economical and environmentally friendly vehicles available, and has a price tag within reach of most consumers.

The Prius is the world's first mass-produced hybrid vehicle, combining a gasoline-fueled internal combustion (IC) engine and an electric motor for propulsion. Configured as a five-passenger family sedan, it is on sale in the U.S. for around $20,000. Its hybrid powertrain gives it impressive EPA fuel economy numbers (52 mpg in the city, 45 on the highway) and allows it to meet super ultra low emissions vehicle (SULEV) standards, which are about 75% more stringent than ULEV and nearly 90% cleaner than LEV for smog-forming exhaust gases.


Toyota Prius.

The first-generation Prius, which sold more than 37,000 units in Japan between December 1997 and May 2000, was optimized to operate primarily in "stop-and-go," low-speed driving environments. Due to higher sustained speeds, typically longer driving distances, more dramatic climate changes, and more stringent emissions requirements in the U.S., the car was re-engineered to improve its driveability and efficiency on American roads.

Primary power for the Prius is provided by an all-aluminum 1.5-L gasoline engine with peak power, for the U.S. model, of 52 kW (70 hp) at 4500 rpm - vs. 43 kW (58 hp) at 4000 rpm for the Japanese-market Prius - and peak torque of 111 N•m (82 lb•ft) at 4200 rpm. The engine has variable valve timing to maximize efficiency across the power band and minimize emissions. The U.S. model is also equipped with a Toyota hydrocarbon (HC) absorber and catalyst (HCAC) system for reduced emissions. Evaporative emissions are reduced by placing a plastic bladder inside the steel gas tank. As fuel is burned, the bladder collapses, minimizing the volume of gasoline vapor that would normally remain in the tank.

The U.S. Prius also benefits from a more powerful main battery pack that is 30% lighter and has 60% less volume than the first-generation Prius'. The electric drive motor features a permanent-magnet design that requires little maintenance and produces its maximum power of 33 kW from 1040-5600 rpm, with maximum torque of 350 N•m (258 lb•ft) from 0-400 rpm.

The electronic controls of the Toyota Hybrid System (THS) allow the Prius to operate on either electricity, gasoline, or a combination of both. The ratio of power provided by each system is controlled, depending on speed and load, to keep the vehicle operating in its most efficient mode. According to Toyota, THS switching goes virtually unnoticed by the vehicle occupants. The key to the system is a power-split device that uses a planetary gearset to send engine power directly to the front wheels and an electric generator that feeds the electric motor and/or battery. The electronically controlled transmission blends the output of the gasoline engine, electric generator, and electric motor to accommodate the desired acceleration and deceleration.

The Prius is fitted with a regenerative "by-wire" braking system to further boost system efficiency. When the vehicle is coasting or the brakes are applied, the motor is turned into a generator, capturing kinetic energy that would normally be lost as heat and converting it into usable electricity to recharge the batteries. When the brake pedal is initially depressed, a computer sends a signal to the regenerative system to slow the vehicle. As more braking power is required, a computer phases in the standard hydraulic brakes. Front disc brakes are teamed with rear drums, and an antilock brake system (ABS) is standard.

Inside, high front- and rear-seating positions make for easy access as well as good visibility. The instruments are centered high on the dashboard at the base of the windshield, making it easy for the driver to refocus from the road to the dash. The audio system is located below the instrument cluster, as is a 5.8-in-wide multifunction touch screen, which can display the condition and energy flow of the hybrid drivetrain.
