Maximum Vehicle Weight

The Good News - I'm a big guy, but I can fit into a 2010 Toyota Corolla. The Bad News - the vehicle is only rated for 825 pounds worth of people and gear. I could easily see regularly exceeding that figure with passengers, pets, and luggage.

Anybody out there know what the practical implications are for exceeding the maximum weight figures posted on the door frame of your car?

Not really about your question--but after I bought a trailer I found out that towing capacity is not very well correlated to how well the towing combination will perform. I am well within my towing capacity with my pickup/trailer, but in some places, I cannot climb a hill faster than 30 miles per hour, and that is with everything straining.

Lee,

Even though the Toyota Corolla has 5 seats, it's really not built for filling all the seats and the trunk, easily exceeding the maximum rated payload. The car is intended to be an economical commuter car for a couple people or a putting around town car for a mom and a couple kids. (It reminds me of the 4-seat Cessna 172 which can only get safely off the ground with 3 average sized adults and no baggage.) If you feel that you would regularly exceed the weight limit of the Corolla, I'd suggest looking for a car with greater capacity. It will drive better, last longer, and you'll be safer.

Exceeding the weight limits set by the manufacturer by 100 lb. won't make the car fall apart as soon as you exit your driveway, but they are real design limits set by engineers. In the long run, you'll pay for it one way or another. Aside from extra load on the drive train and suspension, the brakes were designed to handle a specific maximum gross vehicle weight. Exceed that and they will wear out faster and might not maintain their effectiveness when you really need them. Tires are another concern. My brother-in-law used to have a 3/4-ton Suburban which he occasionally overloaded and towed a large boat with, resulting in repeatedly blowing out good quality rear tires. He never payed attention to the load limits of the vehicle and tires.

If you are an unusually large person, you may also be exceeding the design limits of the driver's seat and seat belt anchor points, even though you "fit" in the car. Small economy cars like the Corolla use every opportunity to keep vehicle weight down by employing thinner sheet metal everywhere. A rear end collision could break the seat loose under your weight. A larger, heavier car would likely be a bit sturdier for a larger person.

I once owned a Toyota Corolla. It was a great, economical little car for me and my wife at the time. For the past 25 years we've been driving medium sized Volvos, a wagon for me and a sedan for the wife, rated for a payload close to 1,000 lb. and only carrying 3 people and some luggage on long trips. The cars handle the load well and still get 28~30 mpg on the freeway. After my wife got rear-ended, totaling her old Volvo sedan, she wouldn't let me replace it with anything less than a newer Volvo sedan. There's a lot to be said for a little larger, heavier built vehicle.
