2018 TOYOTA PRIUS PRIME

ASG’s annual study found the 2018 Toyota Prius Prime to hold the smallest carbon footprint of any model year 2018 car in the North American market, earning the distinguished BEST ENVIRONMENTAL PERFORMANCE award. In ASG’s data-driven automotive life-cycle assessment, the Prius Prime not only won its class, but also outperformed all 1,664 (with trim variants) vehicles assessed.

In ASG’s all-around performance assessment – the combined environmental, social and economic performance analysis - the Prius Prime furthered its winnings to earn the highest distinction as ASG’s BEST ALL-AROUND PERFORMANCE CAR OF 2018. The PHEV outperformed all conventional and alternatively powered vehicles to take the top honor.

When the Prius was first launched in the U.S. market in 2000, the world’s first mass-produced hybrid boasted of its 41 MPG combined (city/hwy). With a 117.5 lb. NI-MH battery pack and a curb weight of 2765 lbs., Toyota lead the industry into the hybrid era with this compact model. 18 years later, the Prius Two Eco is equipped with a lighter lithium Ion battery that achieves 56 MPG combined – a notable 15 MPG improvement.
To see what this improvement means in CO2 terms, ASG conducted a comparative life-cycle assessment, and found the 2000 Prius to hold 295 grams of CO2-e emissions per mile driven life-time (attributing CO2 emissions from raw material extraction, processing and manufacturing, through vehicle use with fuel inputs, to vehicle end-of-life). ASG found the 2018 Prius Eco to hold 226 grams of CO2-e emissions per mile driven life-time, a 23% reduction over the 2000 model and a significant stride without a full technology leap.
While this is notable, the model that places the Prius at the top of ASG’s 2018 API, is the Prius Prime. Toyota is bridging the technological gap once again and leading us into the battery electric era with this plug-in hybrid model, featuring 133 MPG-e and a 25-mile all-electric capability. According to ASG, this lithium-ion plug-in hybrid model holds 181 grams of CO2-e emissions per mile driven life-time, a life-cycle carbon footprint that is 39% less than the first generation Prius.
