Toyota Indiana celebrated a significant milestone as the 1-millionth hybrid vehicle—a Wind Chill Pearl 2025 Toyota Sienna Platinum—rolled off the line at the Princeton plant. Sienna has been assembled at Toyota Indiana since 2003, with the all-hybrid model being the latest iteration built by the plant’s 7,650 team members.

Sienna is part of Toyota’s robust lineup of electrified powertrain options. In May, Sienna sales were up more than 95% year-over-year while sales of electrified vehicles accounted for nearly half of Toyota’s sales volume for the month. This diverse portfolio of electrified vehicles will help propel Toyota toward its goal of carbon neutrality by 2050.

Toyota Indiana represents an $8-billion total investment and has donated more than $54 million to local organizations since breaking ground in 1996.
