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.
For better traction, the Sienna has larger tires than the ProMaster City Wagon (235/60R17 vs. 215/55R16).
The Sienna SE’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 L/LE/XLE has standard 17-inch wheels. Only 16-inch wheels are available on the ProMaster City Wagon. The Sienna SE has standard 19-inch wheels.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Sienna can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The ProMaster City Wagon doesn’t offer run-flat tires.
The Sienna FWD has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the ProMaster City Wagon; it requires you to depend on roadside assistance and your vehicle will have to be towed.
The Sienna has standard front and rear gas-charged shocks for better control over choppy roads. The ProMaster City Wagon’s suspension doesn’t offer gas-charged shocks.
For better handling and stability, the track (width between the wheels) on the Sienna is 7.7 inches wider in the front and 6.8 inches wider in the rear than on the ProMaster City Wagon.
For better maneuverability, the Sienna AWD’s turning circle is 4.6 feet tighter than the ProMaster City Wagon’s (37.4 feet vs. 42 feet). The Sienna’s turning circle is 4.5 feet tighter than the ProMaster City Wagon’s (37.5 feet vs. 42 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 (except L) offers an optional power liftgate, which opens and closes automatically by pressing a button. The ProMaster City Wagon doesn’t offer a power cargo door.
The Sienna’s standard towing capacity is much higher than the ProMaster City Wagon’s (3500 vs. 1914 pounds).
When two different drivers share the Sienna Limited, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The ProMaster City Wagon doesn’t offer a memory system.
The Sienna Limited’s standard easy entry system 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’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.
The Smart Key System optional on the Sienna (except L) allows you to unlock the doors, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. 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 vandalism, such as sugar in the tank and fuel theft. 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 Limited Premium’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. 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.
When the Sienna Limited 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 LE/SE/XLE/Limited’s standard 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.
On extremely cold winter days, the Sienna Limited’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 Premium has a 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.
