Toyota revealed the new Sienna and Venza yesterday. I didn't watch the event, but found the press releases afterward. Details:
2021 Venza:
-2.5L Dynamic Force 4-cylinder
-3 electric motors
-AWD only
-219 system HP (same powertrain as RAV4 Hybrid)
-40 MPG combined
2021 Sienna:
-2.5L Dynamic Force 4-cylinder
-2 electric motors/3 optional
-AWD optional on all trims
-243 system HP
-33 MPG combined
The jump in the Sienna's MPG is enormous; the current Sienna is rated 21 (2WD)/20 (AWD). That's a reduction from 5 gal/100 mi to 3 gal/100 mi.
