The Naturally Aspirated V8 Enthusiasts Should Hoard Before 2026 Ends
Over the past decade or so, the naturally aspirated V8 has quietly dwindled in numbers. With the proliferation of the turbocharged four and six-cylinder engines, the naturally aspirated V8 is fast becoming a collectible asset. A finite set of high-revving, fire-breathing V8s have started to appreciate and, in turn, are being snatched up by enthusiasts left and right.
If you think this is the same old “V8s are dying” eulogy, then you would be mistaken. It is a more narrow, interesting argument: a scant few engines, already built in finite numbers, are appreciating, according to data from auctions. In turn, they’re commanding premiums in the swap market and are being stockpiled by builders before they dry up entirely. Let’s talk about which engines they are, from brands like BMW, Ford, and the like, and why the money is flowing toward them, and how to spot one before anyone else.
The Final Generation
Every enthusiast engine eventually gets a “last of its kind” label, and the naturally aspirated performance V8 is going through that right now. These analog beauties have a big displacement, are high-revving, and are entirely dependent on airflow rather than a turbocharger or battery pack. In part, the shift has had to do with emissions and regulations, but the market has also shifted entirely in what is wanted and needed out of a performance engine.
When The Redline Was The Whole Point
Forced induction allows an engine that might not have enough displacement to get the car up to speed quickly enough. The cost is that there is a lag between the induction itself and the power transfer to the wheels. With an N/A V8, on the other hand, you get all that power delivered to you almost instantaneously in a linear fashion rather than hitting a torque plateau in a turbo. Some of the highest-revving V8s out there are: BMW’s S65, found in M models, that redlines to 8,300 RPMs, Ford’s flat-plane Voodoo at 8,250, and Ferrari’s 458 engine that screams to 9,000 RPMs. Natural aspiration aside, it is really that scream and engine note that people seeking these types of engines are after.
What Killed The Naturally Aspirated V8
The N/A V8 wasn’t gutted overnight. It was slowly and methodically put to rest by industry-wide forces. The first is the obvious downsizing with a smaller, boosted engine that achieves bigger numbers and better fuel economy. The second is the obvious major pivot the industry has made to electrification. Even brands like Lamborghini are putting hybrids in their supercars, even though they still sport naturally aspirated V12 engines. That, in and of itself, is a clear sign of the times.

The Quiet Hoard
Have you ever heard the expression, “follow the money?” It may be a saying, but a saying with a lot of truth behind it. The auction block and parts catalog are where the money is and where it should be, followed with regard to the performance of NA V8s. These engines are quite literally being stockpiled not only within the cars that house them, but also as bare blocks, in order to give potential buyers a chance to swap them if they want. Here’s the actual roster being hoarded and the numbers behind it.
The Engines Builders Are Buying Up
There are five engines within this conversation that really prove the point. It’s not just one country’s V8 either; it pertains to German, Japanese (like Lexus), Italian, and American-made V8s all across the board. Every one of them is a genuine, naturally aspirated V8 that has a limited production run. For the majority of these, they were also the last production run of their engine family:
- BMW S65 (E92 M3): 4.0L, 8,300 rpm redline.
- Lexus 2UR-GSE (LC 500): 5.0L, 471 hp at 7,100 rpm
- Ferrari F136 (458 Italia): 4.5L, flat-plane crank, 9,000 rpm redline.
- Dodge 392 HEMI: 6.4L, 475 hp, 470 lb-ft.
- Ford Voodoo (Shelby GT350): 5.2L flat-plane, 526 hp, 8,250 rpm.
What The Bring A Trailer Comps Actually Show
As stated previously, following the money in the auction space is where this whole thing starts to become a reality. The most obvious case of this is the BMW S65 engine. Most recently, there was a 725-mile E92 M3 Competition spec that sold for $212,000 in April 2026. It absolutely obliterated the E9X’s high of $133,000. Standard transmission competition cars have jumped 10 to 15 percent within an 18-month period. Again, this jump isn’t limited to cars either. Ford offered the Voodoo as a crate engine. It sold out completely, and you could probably find a GT350 with one right now on Bring A Trailer.

While big engines are on the chopping block, the V-6 continues to carve out its place in the modern era of efficient vehicles.
Why Prices Are Climbing Now
Metaphorically speaking, this is something of a “last call” on these kinds of engines. Appreciation on this side of the market is predicated on the fact that supply is shrinking and demand is rising. When you factor in the “last of its kind” into the equation, you end up with a sustained upward pressure in this space rather than a spike and a downward spiral.
“Last of Its Kind,” Priced Engine By Engine
Every engine has a different story to tell, price-wise. The Ferrari 458 is obviously in the exotic category, and while other brands like Maserati didn’t necessarily use the 458, their walking away from NA Ferrari V8s is the clearest indication of that market. The 458 is now trading in the low-to-mid $200,000s. The Lexus LC 500, on the other hand, costs around $100,000 new. You can still technically buy these from the dealer, giving you an opportunity to get your hands on one before it’s gone. Maybe even giving you an appreciating asset.
If you think about it, the entire swap market was almost built on the LS. If you’re a time-tested enthusiast, you’ve probably made the joke with your friends to “LS swap” something ridiculous like a Honda CR-V. The successor to this now-foregone engine is something like the Voodoo, the S65, or the 392 HEMI.

The Collector’s Window
Realistically, this sense of urgency doesn’t necessarily have to do with Washington tightening its screws around emissions. As of 2026, federal emissions have actually loosened for the first time in a few decades. The EPA repealed its federal greenhouse-gas standards for vehicles, constituting one of the single largest deregulatory actions in its history. This rollback, among cries from consumers, is exactly why Dodge resurrected the 392 HEMI for 2026. Now, high-output V8s still can’t be sold in states like California, which employ the “CARB rules.” Other automakers are walking away from these engines by choice and are going for electrification. Most of these engines ended production a long time ago, but some are either still in production and taking their final bow (Lexus 2UR-GSE) or they’re locked out of certain states like the 392 HEMI.
- Lexus 2UR-GSE / LC 500: production ends August 2026
- BMW S65: ended 2013
- Ferrari F136: ended 2015
- Ford Voodoo: ended 2020
- Dodge 392: back for 2026
How To Spot The Next Winner
The five engines we’ve already touched on are obvious, established plays. Where the kicker lies is in finding out which one is going to be the next in line. There are three rules you can employ to identify the next naturally aspirated V8 you should consider acquiring. First, anything that could be considered the “swan song” of a production vehicle. Second, an engine whose performance cannot easily be faked by forced induction or electrification. This engine sports either a flat plane crank or something that revs well past 7,000 RPMs. Finally, a model that has a finite production run with a dedicated owner base.
Condition, Miles, And The Paperwork That Pays
Once you’ve sourced an engine with all of these characteristics, run, don’t walk, to buy one. Next, finding the right car that houses said engine is a discipline in its own right. Low mileage and originality command the highest premiums, but documentation of engine maintenance is worth more than anything else, especially on engines that have faults in their stars. For example, the Ford Voodoo sucks down oil like it does gasoline. The Ferrari needs a second mortgage to service it. What commands a true premium are low-mileage engines, original (one-off) variants, complete service history, and unmodified examples.
