Matt,
If the world were %100 EVs and say the drivetrain of them never sold in your store (dealers only). Lastly add in that EV brakepads last about 4 times longer (because of regen). How much of you business would go away?
For the record, I don't see a 100% EV vehicle population happening in my lifetime. Even if there were only EV's sold from this day forward, gasoline cars are going to be around for a long time. We still have quite a few cars built in the 1980's on the roads today, by comparison.
But I'll take your scenario, a 100% EV population. Surely we would lose any ignition and emissions systems business, and engine air, oil and fuel filters as well (cabin filters would continue to be in use). The little bit of engine parts we still sell, the bulk of which are timing products, are history too. There may still be some gaskets associated with EVs (in the drivetrain I suppose), but they would be a minor product line. Accessory drive belts will most likely be a thing of the past.
You say the brakes last 4 times as long; I'll take that figure for now, but really what kind of studies have been done? I would propose a theory that the early EV adopters are very interested in hypermiling and closely monitor their energy usage (including regen). As the general populace begins driving EVs, they're going to be running up on people and braking at the last minute, just as they're used to doing now. (It's just a theory) In any case, the brake business would take a hit, maybe not as drastic as you expect. No one knows.
As our business mix is today then, you could probably see as much as a 50-60% cut in our business. But you or I can't really say in what areas the aftermarket would pick up market segments. Not everyone takes their car to the dealer for service, that's why there are millions of independent repair shop all over the country, including some of the biggest names in national chains, like Midas, NTB and any of your Firestone-type service centers. All of these types of places buy parts from the aftermarket, which is huge business. People are always looking to save money; that's why Wal-mart exists. So the dealers won't get all of that business, but in any case I sell to several dealers also.
I'm not familiar with what goes into an EV drivetrain, but I'm willing to bet there are all manner of controllers, relays, sensors, ECMs and whatnot. Let's not forget stability control systems as currently mandated. I'm sure there will be sufficient demand and need for the aftermarket to step into these market segments, and others which we currently cannot forsee. Let's not forget that many aftermarket suppliers are OEM suppliers too. And our product mix is constantly expanding into new areas. For example, a few years ago we didn't offer replacement computer controlled suspension parts; today we do.
The Model S weighs, what, almost 5000 pounds? How much of it is the battery? What accounts for the rest? I guarantee it isn't made of unicorn farts. Any component built by humans is prone to failure, even an electronic piece (especially an electronic piece). Also consider how many electrical connections might be in a Model S. One of my TVs randomly stopped working over the winter, and it sits stationary in a climate controlled environment,
and has no moving pieces. The Model S (and any other mainstream, non-limited-practicality EV, unlike the Roadster) are going to be asked to perform day after day, in good conditions and bad, exposed to rain, snow, heat, dirt, cold, pothole impacts and God knows what else, while also keeping its occupants warm (or cool), entertained and comfortable. It's a lot to ask of a product, one which I reiterate is the most complicated thing you will ever own (it's a miracle that cars do what they do).
So there will be plenty of parts for us to sell, notwithstanding all the inventory currently in my building which has nothing whatsoever to do with a gasoline engine. Therefore there will also be plenty of work for mechanics of all types to perform. And since the EV revolution is not going to happen overnight, as in our little hypothetical here, I am not too worried about a sudden and precipitous drop in our sales.
But it is curious how many here are so eager to wish that upon me and others in the field. I currently employ 50 people, all of whom put dinner on their families' tables through auto parts sales to repair shops. The mechanics at those shops put dinner on their families' tables through repair of customers' cars, and those customers are able to go to their jobs with those cars, and put food on their families' tables, as a result. People and cars like yours and others on this forum. Many of my parts are sold to fleet operators, the types of people who deliver the goods and services people buy and use every day, or build the houses in which they live. My one auto parts business directly benefits and impacts thousands of people; there are 7000 more NAPA stores around the country, and who knows how many of other affiliations.
So I'll ask you, what would be the impact to the employees of these stores, and to the nation's economy, if they, and all the repair shops as well, were to simulateously fail? Luckily for all of us, this isn't going to happen, and I don't think a bunch of huge aftermarket companies, led by smart people, would stand by and not adapt as the mix of the cars on the road, their very reason for existence, shifted under their watch.
VFX, I know you were just asking a simple hypothetical question, but I can't understand the disdain carried here (not necessarily by you) for my business, just because I happen to sell parts to repair "evil ICE cars". Down the road, you just might need a guy like me around.
