SUV vs Minivan: which is safer?

Post by learning_head » Thu Feb 01, 2018 8:57 am

For someone looking for a larger car that can accommodate 2 car-seats + 3 adults or maybe even 4, safety-wise, would you go with an SUV or a Minivan?

When I look at safety ratings online, they only look at same-weight class vehicles. I did not find comparisons across weight classes. Any suggestions?

My understanding is that higher-weight vehicles are safer which might suggest a minivan, but SUVs tend to have more "junk" in front making them probably safer in frontal collisions. SUVs are also higher than Minivans which is safer in some respects (e.g. can better see ahead over other cars and collisions with "shorter" cars don't affect you as much); but make SUVs more prone to rollovers.

Another thought: cars that are larger by size are harder to "fit", making them more likely to be involved in accidents. So I guess the goal could be smaller size but larger weight? Am I thinking about this straight?

The lines are blurring between SUVs and Minivans now that many SUVs are car-based. However, typically SUVs are less safe due to their higher center of gravity which contributes to rollover accidents, which have a particular tendency to be fatal. I know at least three friends who have died in rollovers, two in Jeeps and one in a Suburban.

The last study I've seen documenting this was older -

@lthenderson, thanks but those other threads, while similar, often get into other topics. My question is specific to safety comparison.

Some data here for you to peruse

In general, there's not a huge difference between SUVs and minivans anymore, as the SUV rollover risk that was prevalent during the 90s and early 2000s has been somewhat addressed

Keep in mind that there's probably inherent correlation to the types of people (and their driving styles) that might buy a particular car.

I'd worry more about your own personal driver behavior than whether you buy a SUV or minivan. A little bit more focus on defensive driving would go a lot further in reducing risk than putting in a lot of effort splitting hairs over which car to buy

If you avoid the body-on-frame SUVs (typically just the really big ones) and stick with a unibody SUV (e.g., the Honda Pilot, the Toyota Highlander), there probably isn't a significant difference in terms of safety today. It really comes down to which will most comfortably fit the people you routinely haul and which you prefer to drive. If you look at accident numbers, minivans win, but that likely has more to do with who drives minivans. Minivans are cheaper to insure for that reason and because they are less likely to be stolen.

Safety is a function of: how much you drive, where you drive, the conditions you drive in, your car's accident avoidance capabilities, your driving capabilities and alertness, and finally, what happens to your car in a crash, which is itself a function of how it was engineered, the safety mechanisms in place, and finally, mass. Yet, everyone seems to focus on the last thing.

When you plot the fatality rates by vehicles you find that the correlation between mass and safety has a lot of error. What's the error driven (ahem) by? All the other factors. Just a thought.

I would choose a minivan if concerned about safety as their lower center of gravity would make them handle better (YMMV depending on the particular model).

Last time I checked the Odyssey had zero driver fatalities per million miles driven.

Go with AWD SUV for sure if you live in an area with snow and ice (although be aware that AWD makes less of a difference with ice).

In general, vehicles on truck frames (many SUVs, especially larger ones) are heavier and have a higher center of gravity. While a heavier vehicle MAY offer some benefits in a crash (at the expense of the people in the other car), they take longer to stop, can't change direction or avoid accidents as well, accelerate slower, get worse gas mileage, and are more prone to roll over. On the other hand, they are better at going off-road and towing things.

Vehicles on car frames (minivans and some "crossover" SUVs) are lighter with lower centers of gravity, so they stop sooner, handle/change lanes better, avoid rollovers better, etc.

Personally, I would never buy a vehicle on a truck platform (unless I needed to go off-roading or tow something, neither of which I do), and I would not want my kids riding in one. I would far far rather have a better chance of avoiding an accident (by superior braking/handling/rollover resistance) than to get in an accident and hope the extra mass will help me (which it may or may not, it sure doesn't help in a rollover or driving into a creek).

Also, I know this is a tragedy of the commons thing, but do you think it's generally safer if EVERYONE rides higher, bigger, heavier vehicles? Or the opposite? (Note I'm not saying to get a SmartCar, I'm talking about minivans vs. SUVs. Generally minivans are better at hauling people in comfort and safety, assuming you're doing it on paved roads without towing a boat behind you.)

Basically a heavy car with a low center of gravity does well in crash testing and has less rollover risk. Many SUVs are "crossovers" and based on car or minivan platforms and these seem to be the safest SUVs.

Check out www.informedforlife.org and peruse their list of vehicles in the safest 1%. Several minivans (Honda Odyssey, Chrysler Pacifica) and crossover SUVs (Acura MDX, Acura RDX, Kia Sorrento) make their list of safest vehicles. No truck based SUVs make the cut.

Minivan. And a minivan is much more family friendly. I have many family members who had Pilots and Highlanders who were much happier when they upgraded to Siennas and Odysseys.

Safety stats are misleading. We collect those stats on a vehicle model basis, but not on a driver basis. Minivans attract people who aren't as interested in performance, sporty appearance, what others think about them and their cars etc. This effect is most strongly apparent in sports cars, or very sporty cars such as Camaros and Mustangs. They attract drivers who want the kind of performance they offer. That performance, acceleration, cornering, etc. is often seen in aggressive driving virtually all of which is illegal. But, the affect is also seen to some degree in some SUV's. People who want a sporty ride may sometimes drive their ride in a sporty fashion.

Most people, given a chance to drive a car capable of 0-60 in 3 seconds, will at some point try it out. You won't find many Minivans out in a heavy snowfall. But you will see 4WD SUV's out there.

With the modern safety features that can help control car behavior in curves, following, lane departure, SUVs can be as safe as a minivan. At the end of the day, it is still up to the driver to operate safely.

Correction: According to the linked article, that is "zero driver fatalities per million registered vehicle years."

There are nine vehicles listed with the distinction of zero driver fatalities. One is a minivan (Honda Odyssey), two are cars, and six are SUVs of various sizes and types. One of the SUVs (Toyota Sequoia) is a large, heavy, body-on-frame type. Here is a quote from the article:
One striking thing about the group of zero-death vehicles — aside from the sheer number — is that two-thirds of them are SUVs.

A decade ago, SUVs had some of the highest rates, due to their propensity to roll over (see Status Report special issue: driver death rates, March 19, 2005). However, the spread of electronic stability control (ESC) through the fleet has dramatically lessened the risk of rollover crashes in these and all vehicles. The rollover death rate of 5 per million registered vehicle years for 2011 models is less than a quarter of what it was for 2004 models.

With ESC dramatically reducing rollover risk, the inherent advantages offered by SUVs' greater size, weight and height emerge more clearly. Today's SUVs have the lowest driver death rate of any vehicle type.

It's impossible to make any kind of useful generalization. Is there any strict definition of "SUV" or "minivan"? Even if you are comparing 2 specific car models, what do you mean by "safety-wise"? Frontal collision? Offset frontal collision? Frontal collision avoidance? Airbag performance? Headlight performance?

Also, there is a lot of "conventional wisdom" perpetuated out there that is simply incomplete or untrue. For example it's simply not true that a car's weight correlates with it's safety rating. For example, which is safer in January on a dry road: a smaller car with winter tires, FWD, radar front collision avoidance vs. bigger taller heavier car with all season tires, AWD, and a bigger bumper? Nobody can know. Accidents are very complicated systems involving many different factors and only some of them relate to your car.

The most recent safety changes have been the widespread availability of electronic safety aids in regular non-luxury cars e.g. frontal collision prevention, automatic emergency braking, blind spot monitoring, adaptive cruise control, adaptive LED headlights, rear cross traffic collision prevention, lane departure prevention, night vision, etc.. Some manufacturers include such safety systems as standard, while others are optional add ons. Make sure to understand what you are buying (dealerships are almost always clueless). For example, some cars will automatically apply brakes at highway speeds and earn a "Superior" frontal collision rating only if the optional radar adaptive cruise control option is purchased. Without the option, the car may only automatically apply brakes at city speeds.

With modern uni-body SUVs and vans being pretty similar (some are even built off of the same vehicle platform and assembled in the same plants), one differentiator is that most minivans should have a lower center of gravity than most SUVs. Crash-worthiness and survivability might be very similar, but a lower center of gravity (and different handling characteristics) should give the minivan the edge in accident avoidance in the first place.

Going slightly off topic (beyond safety):
Car seats? Two words: sliding doors. Do not underestimate the benefit of sliding doors when loading and unloading kids (with and without car seats) from ages 1 to 18. Especially in parking lots, frequently undersized residential garages, and school drop off and pickup lanes (power sliders help here).

Many people can not get over the supposed un-cool factor of a minivan versus an SUV, but if you look at it from a practicality standpoint, it seems like a no-brainer. It's hard to beat the actual usable cargo and people capacity and the ease of entry/exit with the minivan.

Also, for those considering SUVs being preferred in snowier climates: FWD minivan with decent tires and a competent driver beats an overconfident idiot in an 4WD/AWD SUV, at least in moderate snowfall. FYI, if you do need more capability, Toyota Sienna is available with AWD.

I currently have SUV and considering Minivan as replacement. Why is it an upgrade? When factoring overall cost (i.e. insurance), isn't the minivan less expensive. I assume upgrade is restricted to size difference.

You are overthinking this. The model-to-model variance will be there but overall vehicles have become much safer over the years. Having to reach a few more inches to get to a storage bin based on where you adjust your seat might have more effect on safety than the theoretical difference between the engineering of one crumple zone and another.

Definitely, a minivan. We have an Odyssey and a 4-Runner. Odyssey easier to enter and exit, drives much smoother, holds more people. Larger size allows easier use of child seats, mileage better, insurance rating better. Of course the 4-Runner is on a truck base and rides rougher, but it is a very reliable vehicle.

From what I’ve read a minivan is probably safer due to its lower center of gravity. SUVs
Tend to have more rollover risk due to sitting higher, although the amount of risk is highly dependent on the width of the SUV and how high it sits. The ones on a car frame are probably relatively safer.

When evaluating risk people tend to only evaluate risks they can’t control, like a head on collision, and thus tend to think big vehicles are safer. They don’t focus on how they will drive the vehicle and what that does to your risk, such as rollover risk. How many times have you seen people in SUVs or pickups tailgating you at 80mph. The fact that they are sitting higher and can see more of the road immediately in front of them gives them the illusion of more control and they drive more dangerously.
