As a savvy owner of a Prius c hybrid, I think I have some insight into this... Basically, the brake pads *are* used quite a lot by aggressive drivers who tailgate and have to brake hard when the car in front of them slows down. People who drive with a proper following distance ahead of them will rarely have to use the disc brakes.
Hybrid vehicles (and EVs, probably) have smaller brake pads than similarly sized conventional vehicles (though the actual stopping power of the disc brakes in an emergency is just as good as regular cars). The brake pads are about half as thick on my Prius c as the brake pads on my Honda Civic. That's because the manufacturer expects you to use them less often. I'm sure there are some insane drivers out there who can burn through the brake pads on a vehicle like mine in well under 50,000 miles, but those same people would burn through the brakes on any vehicle just as quickly.
I've learned to "feel" the difference between the cut-over between regenerative braking and the disc brakes. The disc brakes slow you down WAY faster. There's not a discrete and obvious jolt when you gradually depress the brake pedal; it's incredibly smooth; but to use an analogy, as long as I'm slowing down at about the same rate as a truck can slow down when using the jake brake (engine braking - that loud "farting" sound that large trucks sometimes make when slowing down), I'm using the regenerative braking system only. If I'm slowing down much faster than that, the disc brakes are being engaged (the brakes and the regenerative braking can be active at the same time, unless you are braking at what would be considered "emergency" speeds, in which case the regenerative braking system disengages, perhaps because it can't handle that amount of torque or current).
As for the article itself: 24 percent?! That's total bullshit.
The Prius c is literally a Yaris Hybrid (it's marketed as such in some parts of the world). It's the Toyota Yaris -- a compact car -- with the Toyota Hybrid Synergy Drive in it. So, it's a Yaris, *plus* the weight of the HSD.
The curb weight of the Yaris is 2335 pounds. The curb weight of the Prius c is 2500 pounds. That's only a 7.066% increase. That's a far, far cry from the 24% the article cites.
OK, you say, let's look at *electric* vehicles specifically, not just hybrids. Because hybrids don't have to lug around 500 pounds of lithium-ion batteries. Hybrid batteries tend to weigh under 200 pounds, with the smallest hybrids' ~1 kWh batteries weighing less than 100 pounds.
Let's take the Chevy Spark. The conventional Spark weighs in around 2270 pounds. The EV? 3000 pounds. That's a 32% increase for basically the same passenger and cargo volume. Fair enough. But 3000 pounds isn't out of this world, and is in the ballpark of many upscale compact cars like the (conventional) Honda Civic.
Another example. The 2016 Nissan Leaf weighs around 3150 pounds. I did some research to try and find a conventional vehicle with similar interior measurements (headroom, cargo space, etc.) and I came up with this: The 2016 Honda Civic EX has a total (usable) interior volume of 110.1 cubic feet with a curb weight of 2799 pounds. The 2016 Nissan Leaf has an interior volume of 116 cubic feet. So for 6 more cubic feet of interior (5.4% more), the vehicle weighs 351 pounds (25.4%) more.
Based on these limited comparisons, it seems like the article's claim about the increased weight of electric vehicles is factual. However, it is absolutely not valid to make the leap to saying that plug-in hybrids or conventional hybrids are anywhere near as bad in terms of added weight.
What I'm not convinced of, however, is the severity and environmental impact of tire and brake wear, regardless of vehicle weight. EVs and hybrids also run with low rolling resistance tires, which should reduce the amount of tire "stuff" in the air, in any case. Did they take that into account?
However, switching out a gasoline engine for a TDI diesel engine adds about 300 pounds to a sedan-sized vehicle. A 2900-3000 pound, gasoline-powered Volkswagen Jetta suddenly weighs almost 3300 pounds when putting in a diesel. That's a 10% increase, a bigger increase percentage-wise than hybridizing a Yaris. So shouldn't the article also go after diesels for adding weight to vehicles and contributing to emissions, on top of the particulate matter emitted by the diesel's tailpipe?
In summary:
- Article claims EVs weigh "24% more": Appears mostly factual, when comparing vehicles that have an EV model and a conventional model, or comparing vehicles across brands that have similar interior volume.
- Someone might think that hybrids or plug-in hybrids are just as bad (not saying the article argues this): Nonsense. Don't be mislead into thinking that hybrids contribute to this problem. With a very small (and light) battery that requires relatively little well-to-wheels heavy metals to produce, and a mere 5-10% increase in vehicle weight, the reduced brake usage due to the regenerative braking, coupled with the 20-50% reduced tailpipe emissions for similarly-sized vehicles, should land hybrids squarely in the "win" column, in terms of a net emissions savings.
- Diesels have much worse tailpipe emissions (in terms of particulate matter, the stuff the article demonizes so aggressively, and rightly so I guess) AND weigh a lot more than gasoline-powered vehicles. I'd think they'd be an even bigger target, especially considering there are a lot more of them on the road than there are EVs!
Afterthought: Diesels and conventional vehicles seem to be at a standstill in terms of how efficient they can be, and also in terms of how light they can be for a given interior volume / cargo capacity. What's *not* at a standstill is the transformation of the electric grid from being primarily derived from fossil fuels to depending on renewables (and nuclear). Another thing *not* at a standstill is the energy density of batteries; current lithium chemistry may have reached its limits, but there are numerous next-generation battery chemistries that are on the verge of being commercialized and may bear fruit before the decade is out. If you don't like the environmental picture of EVs, just wait a while. Nothing will change on the conventional side, while EVs continue to get cleaner.
