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 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 and rearview cameras.

The Toyota Sienna weighs 928 to 1043 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 Pick Plus” for 2021, a rating granted to only 68 vehicles tested by the IIHS. The ProMaster City Wagon has not been tested, yet.

Warranty

Toyota pays for scheduled maintenance on the Sienna for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Ram doesn’t pay scheduled maintenance for the ProMaster City Wagon.

Reliability

The battery on the Sienna is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Sienna’s battery 20 to 30 degrees cooler, its life is increased by years. The ProMaster City Wagon’s battery is in the hot engine compartment.

J.D. Power and Associates rated the Sienna third among minivans in their 2021 Initial Quality Study. The ProMaster City Wagon isn’t in the top three in its category.

J.D. Power and Associates’ 2021 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Toyota vehicles are more reliable than Ram vehicles. J.D. Power ranks Toyota fourth in reliability, above the industry average. With 25 more problems per 100 vehicles, Ram is ranked 16th.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Toyota vehicles are more reliable than Ram vehicles. Consumer Reports ranks Toyota second in reliability. Ram is ranked 7th.

Engine

The Sienna’s 2.5 DOHC 4-cylinder hybrid produces 67 more horsepower (245 vs. 178) than the ProMaster City Wagon’s 2.4 DOHC 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the Sienna gets better mileage than the ProMaster City Wagon:

			MPG
Sienna
	FWD	2.5 4-cyl. Hybrid	36 city/36 hwy
	AWD	2.5 4-cyl. Hybrid	35 city/36 hwy
ProMaster City Wagon
	FWD	2.4 DOHC 4-cyl.	21 city/28 hwy

Regenerative brakes improve the Sienna’s fuel efficiency by converting inertia back into energy instead of wasting it. The ProMaster City Wagon doesn’t offer a regenerative braking system.

In heavy traffic or at stop lights the Sienna’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. The ProMaster City Wagon doesn’t offer an automatic engine start/stop system.

The Sienna has 2 gallons more fuel capacity than the ProMaster City Wagon (18 vs. 16 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Sienna higher (7 out of 10) than the Ram ProMaster City Wagon (6). This means the Sienna produces up to 1.1 pounds less smog-producing pollutants than the ProMaster City Wagon every 15,000 miles.

Transmission

The Sienna has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The ProMaster City Wagon doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the Sienna’s brake rotors are larger than those on the ProMaster City Wagon:

	Sienna	ProMaster City Wagon
Front Rotors	12.9 inches	12 inches
Rear Rotors	12.5 inches	10” drums

The Toyota Sienna has standard four-wheel disc brakes for better stopping power and improved directional control in poor weather. Only rear drums come on the ProMaster City Wagon. Drums can heat up and make stops longer, especially with antilock brakes that work much harder than conventional brakes.

Tires and Wheels

For better traction, the Sienna has larger tires than the ProMaster City Wagon (235/50R20 vs. 215/55R16).

The Sienna FWD XSE/FWD Platinum’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the ProMaster City Wagon’s 55 series tires.

For better load carrying, ride, handling and brake cooling the Sienna LE/XLE has standard 17-inch wheels. Only 16-inch wheels are available on the ProMaster City Wagon. The Sienna FWD XSE/FWD Platinum has standard 20-inch wheels.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the Sienna is 7.7 inches wider in the front and 7.6 inches wider in the rear than on the ProMaster City Wagon.

For better maneuverability, the Sienna’s turning circle is 3.7 feet tighter than the ProMaster City Wagon’s (38.3 feet vs. 42 feet). The Sienna XSE/Limited/Platinum’s turning circle is 2.8 feet tighter than the ProMaster City Wagon’s (39.2 feet vs. 42 feet).

Passenger Space

The Sienna has standard seating for 8 passengers; the ProMaster City Wagon can only carry 5.

The Sienna has 45.7 cubic feet more passenger volume than the ProMaster City Wagon (162.5 vs. 116.8).

The Sienna has 6.8 inches more front hip room, 3.1 inches more front shoulder room, 3.1 inches more rear legroom, 7 inches more rear hip room and 4.7 inches more rear shoulder room than the ProMaster City Wagon.

For enhanced passenger comfort on long trips the Sienna’s middle and third row seats recline. The ProMaster City Wagon’s rear seats don’t recline.

Cargo Capacity

The Sienna’s cargo area provides more volume than the ProMaster City Wagon.

	Sienna	ProMaster City Wagon
Third Seat Folded	75.2 cubic feet	n/a
Third Seat Removed	n/a	54.7 cubic feet
Second Seat Folded	101 cubic feet	69.2 cubic feet

The Sienna’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The ProMaster City Wagon’s two swing out doors impair rear visibility, need a lot of clearance, and can block loading in tight quarters.

To make loading and unloading groceries and cargo easier, especially for short adults, the Sienna XLE/XSE/Woodland/Limited/Platinum has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The ProMaster City Wagon doesn’t offer a power cargo door.

Towing

The Sienna’s standard towing capacity is much higher than the ProMaster City Wagon’s (3500 vs. 1867 pounds).

Ergonomics

When two different drivers share the Sienna Limited/Platinum, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position (with optional power wheel adjuster) and outside mirror angle. The ProMaster City Wagon doesn’t offer a memory system.

The Sienna Limited/Platinum’s standard easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The ProMaster City Wagon doesn’t offer an easy entry system.

The Sienna Platinum has a standard heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The ProMaster City Wagon doesn’t offer a heads-up display.

The Sienna’s power parking brake sets with one touch and releases with one touch or automatically. The ProMaster City Wagon has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The Sienna’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The ProMaster City Wagon’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the Sienna the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the ProMaster City Wagon can only operate the windows from inside the vehicle, with the ignition on.

The Pushbutton Start standard on the Sienna allows you to start the engine without removing a key from pocket or purse (Sienna XLE/XSE/Woodland/Limited/Platinum’s Smart Key System will also allow unlocking the doors and cargo door without taking your keys out). The Ram ProMaster City Wagon doesn’t offer an advanced key system.

The Sienna has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The ProMaster City Wagon doesn’t offer a locking fuel door.

The Sienna’s standard variable intermittent wipers have an adjustable delay to allow the driver to choose a setting that best clears the windshield during light rain or mist. The ProMaster City Wagon’s fixed intermittent wipers only have one fixed delay setting, so the driver will have to manually switch them between slow and intermittent. The Sienna Platinum’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

To improve rear visibility by keeping the rear window clear, the Sienna has a standard rear wiper. A rear wiper costs extra on the ProMaster City Wagon.

The Sienna has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The ProMaster City Wagon doesn’t offer automatic headlights.

While driving with high beams on, sensitive light sensors standard on the Sienna detect other vehicles which could be blinded and automatically switch to low beams. The ProMaster City Wagon doesn’t offer automatic dimming high beams.

The Sienna’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Ram only offers heated mirrors on the ProMaster City Wagon SLT.

When the Sienna Limited/Platinum is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The ProMaster City Wagon’s mirrors don’t automatically adjust for backing.

The Sienna’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The ProMaster City Wagon doesn’t offer the luxury of automatic dimming mirrors.

Both the Sienna and the ProMaster City Wagon offer available heated front seats. The Sienna Platinum also has standard heated second row seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the ProMaster City Wagon.

Standard air-conditioned seats in the Sienna Limited/Platinum keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The ProMaster City Wagon doesn’t offer air-conditioned seats.

On extremely cold winter days, the Sienna Platinum’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The ProMaster City Wagon doesn’t offer a heated steering wheel.

The Sienna’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The ProMaster City Wagon doesn’t offer dual zone air conditioning.

The Sienna’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The ProMaster City Wagon doesn’t offer automatic air conditioning.

For greater rear passenger comfort, the Sienna has standard rear a/c vents to keep rear occupants more comfortable. The ProMaster City Wagon doesn’t offer rear vents.

To keep a safe, consistent following distance, the Sienna has a standard Dynamic Radar Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The ProMaster City Wagon doesn’t offer an adaptive cruise control.

The Sienna (except LE) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The ProMaster City Wagon doesn’t offer a house-current electrical outlet.
