In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sienna are reminded to check the back seat if they opened the rear door before starting out. The ProMaster City Wagon doesn’t offer a back seat reminder.
The Sienna has a standard Pre-Collision System, which uses forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The ProMaster City Wagon doesn't offer collision warning or crash mitigation brakes.
The Sienna has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The ProMaster City Wagon doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Sienna XLE/XSE/Woodland/Limited/Platinum has a standard Parking Support Brake that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The ProMaster City Wagon doesn’t offer backup collision prevention brakes.
The Sienna offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ProMaster City Wagon doesn’t offer all-wheel drive.
The Sienna’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The ProMaster City Wagon doesn’t offer a lane departure warning system.
The Sienna Platinum has a standard Bird’s Eye View Monitor to allow the driver to see objects all around the vehicle on a screen. The ProMaster City Wagon only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
To help make backing out of a parking space safer, the Sienna’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The ProMaster City Wagon doesn’t offer a cross-path warning system.
The Sienna’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The ProMaster City Wagon doesn’t offer a driver alert monitor.
The Sienna has standard Safety Connect™, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The ProMaster City Wagon doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Sienna and the ProMaster City Wagon have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The Toyota Sienna weighs 927 to 1042 pounds more than the Ram ProMaster City Wagon. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Sienna its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 77 vehicles tested by the IIHS. The ProMaster City Wagon has not been tested, yet.
