The Toyota Prius made waves upon its announcement in 1995, marking a revolutionary step in the automotive industry. It became the pioneer among gasoline-electric hybrid cars, capturing global attention with its distribution and availability. The term “Prius,” derived from Latin, signifies being the first, original, and leading the way – a fitting name for the debut hybrid vehicle.
This exploration will delve into the Prius’ journey, spotlighting how each generation of the car propelled advancements. It will also shed light on models that have exited the market, alongside intriguing insights into the story of this iconic Japanese hybrid automobile.
1. Toyota Prius XW10 NHW10
Toyota designated its groundbreaking Prius line with both generation and model labels. The initial generation, named XW10, featured the first model known as NHW10.
Unveiled at the Tokyo Motor Show in 1995, the Toyota Prius NHW10 commenced production in 1997, and its debut sales in Japan followed in December that same year.
Primarily launched in Japan, the NHW10 of the first generation garnered esteemed automotive accolades, including the Japan Car Of The Year award. Although primarily available in Japan, a few units trickled into the UK, New Zealand, and Australia via private imports.
Crafted as a subcompact 4-door sedan, the NHW10 pioneered gasoline-electric hybrid technology, positioning Toyota two years ahead of other automakers in this domain.
The electric motor technology implemented in the Prius echoed the potent motors propelling high-speed Japanese bullet trains.
Under the hood of this model lay the Toyota 1.5L DOHC engine. The vehicle’s styling was a product of the collaborative efforts of designers in California, ultimately chosen by Toyota as the optimal design for their inaugural hybrid offering.
However, this early Prius iteration encountered some challenges relating to battery performance and electrical systems when operating in extremely hot climates.
2. Toyota Prius XW10 NHW11
The Toyota Prius NHW11 marked the second model within the XW10 generation of the pioneering Prius line.
Introduced as an upgrade to the NHW10, the NHW11 aimed for global sales, especially targeting the US automotive market.
Debuting in 2001 and maintaining production until 2003, the Prius NHW11 underwent design modifications to enhance power and durability, aligning with the preferences of American drivers who often favored higher speeds and extended distances.
An integral enhancement was the incorporation of an air conditioner as a standard feature, powered by the gasoline engine.
Featuring a 1.5L 4-cylinder gasoline engine and a permanent magnet electric motor, the NHW11 employed nickel-metal-hydride (NiMH) batteries for storing electrical power.
While not the first gasoline-electric hybrid in the US market—preceded by the Honda Insight in December 1999—the Prius NHW11 earned recognition as an Ultra Low Emission Vehicle (ULEV) during an era emphasizing emission reduction. This designation secured Prius owners a $2000 tax benefit on their annual income.
Expanding beyond the US, the Prius NHW11 entered the European market in 2000 and the Australian market in 2001.
However, in 2006, Toyota encountered a setback, recalling around 8500 Prius models produced between 2001 and 2002 due to a manufacturing flaw in the crankshaft position engine sensor.
Even in its early iterations, the Prius demonstrated fuel efficiency as one of its strengths. According to the Environmental Protection Agency (EPA) data, the consumption statistics were as follows.
3. Toyota Prius XW20 NHW20
The XW20 series, the second generation of the Prius lineup, was announced in mid-2003 and entered the American market in 2004. This iteration remained in production until 2009, when the third-generation models made their debut.
Under the model designation Prius NHW20, this new release showcased advancements in its environmentally friendly features, positioning it as a more ecologically conscious option than its predecessors.
Enhancements to its eco-friendly attributes were achieved through a redesign of the vehicle’s aerodynamics, effectively reducing its drag coefficient. Notably, the new body design contributed to a 6-inch or 150mm increase in the overall length of the Prius NHW20 compared to earlier models.
These improvements led the Prius NHW20 to earn the prestigious designation of Super Ultra Low Emissions Vehicle (SULEV) from the California Air Resources Board, highlighting its remarkably low emissions.
A notable innovation was the electric motor-driven air conditioner, a pioneering move by Toyota in the hybrid car market. Additionally, advancements in battery technology translated to reductions in the size and weight of the NiMH batteries integrated into the vehicle.
In contrast to the first-generation models that yielded a production total just over 37,000 cars, the second-generation Prius achieved considerable success, with nearly 1.2 million units sold worldwide.
However, Toyota faced complaints from drivers regarding the Prius NHW20, particularly concerning the quality of the lights, resulting in reduced visibility, as well as instances of headlights suddenly turning off without apparent cause.
The gasoline engine in the NHW20 saw an upgrade to a 1.5-liter fuel-injected 16-valve engine, delivering significant power improvements compared to the preceding version.
According to the EPA, the fuel consumption figures for the Toyota Prius NHW20 are as follows.
4. Toyota Prius XW30
The unveiling of the third-generation Prius, known as the XW30 series, in 2009 marked a significant milestone with the introduction of three driver-selectable driving modes. These modes encompassed an electric-only mode for low-speed driving, an eco-mode optimizing fuel efficiency, and a power mode offering heightened performance capabilities.
Toyota’s commitment to environmental advancement was reinforced by the incorporation of bioplastics in various car components, utilizing plant-based materials as an alternative to petroleum-derived ones.
Innovatively, photo-voltaic cells integrated into the car’s roof not only contributed to cooling the interior but also served as an additional means of maintaining battery charge.
The vehicle’s overall design underwent a transformative overhaul, adopting the profile of a subcompact liftback. This rejuvenated look presented a modern and aesthetically pleasing appearance. Simultaneously, the engine capacity was upgraded to a 1.8-liter engine, infusing the car with more power and versatility.
By introducing an electric-powered water pump, the gasoline engine transitioned to a beltless configuration, thereby enhancing its fuel economy.
However, the third-generation Prius encountered a series of issues, including software glitches, inverter overheating, and safety concerns. These challenges prompted recalls for specific models in the years 2010, 2014, and 2018.
The EPS fuel economy tests yielded the following outcomes for the Prius XW20.
5. Toyota Prius Plug-In Hybrid ZVW35
Derived from the third-generation XW30 series, the Prius Plug-in Hybrid, designated as the ZVW35, made its public debut in 2009, captivating audiences at motor shows in Frankfurt, Los Angeles, and Tokyo.
The Prius ZVW35 retained the core features of the third-generation XW30 but introduced a noteworthy upgrade in the form of lithium-ion batteries, replacing the conventional NiMH batteries. This transformative shift empowered the car with the capability to recharge through a standard household electrical outlet or dedicated charging stations.
An eminent advantage of the Prius Plug-in Hybrid was its electric-only mode, allowing it to travel an impressive distance of 14.3 miles or 23km on electric power alone, prior to necessitating a recharge.
The integration of lithium-ion batteries in the Prius Plug-in Hybrid represented a significant leap forward, aligning with evolving trends towards enhanced energy efficiency and environmental sustainability.
