Are Naturally Aspirated Supercars Worth More Than Turbocharged Ones?

Short answer: partly true, and often oversimplified. Emissions rules have pushed almost every manufacturer toward turbocharging and hybrid assistance, making the remaining naturally aspirated engines genuinely rare and desirable, which supports value. But turbocharging hasn’t hurt values the way purists once feared – the best turbo cars hold strong money because they’re brilliant, significant cars in their own right, not despite their engine layout.

There’s a growing belief in the enthusiast market that naturally aspirated supercars are becoming the blue-chip end of the segment, and that turbocharged and hybrid cars will never quite reach the same values. Like most pieces of received wisdom repeated often enough to sound like fact, it’s partly true and partly an oversimplification of something more nuanced. Here’s how it actually plays out when you look at real Australian used-market pricing rather than forum consensus.

Why Naturally Aspirated Cars Are Gaining Status

Emissions regulations and the ongoing search for more power with less fuel burned have pushed almost every manufacturer toward turbocharging, and increasingly toward hybrid assistance on top of that. That makes the remaining naturally aspirated engines – Porsche’s GT3 flat-six, Lamborghini’s naturally aspirated V10, the last of the big naturally aspirated V12s – increasingly rare in a way that wasn’t true even five years ago. The Aventador SVJ is a particularly clean example: it’s explicitly the last naturally aspirated Lamborghini flagship, and that finality is already reflected in how the market treats it. Rarity plus a genuinely beloved character is exactly the recipe that has historically supported long-term value in the classic car world, and the same dynamic is now playing out with modern naturally aspirated engines as they become the exception rather than the rule.

Where the Theory Breaks Down

Turbocharging did not hurt values the way purists feared it would when the shift first began a decade ago. The Ferrari 488 and F8 Tributo both hold strong money in the Australian used market despite being twin-turbocharged, precisely because they are brilliant, significant cars with their own genuine engineering story – our F8 Tributo review covers exactly why it’s earned its own “last of its kind” status despite running turbos rather than a naturally aspirated engine. Value is driven fundamentally by desirability, rarity and genuine significance within a model’s lineage, not by the induction system on its own. A great turbocharged car will comfortably beat a mediocre naturally aspirated one in resale terms every time – the engine layout is one input into value, not the whole equation.

The Porsche Counter-Example

Porsche’s own model range is the clearest illustration of how this actually plays out in practice. Our piece on why Porsche 911 values hold better than any other sports car in Australia shows that both the naturally aspirated GT3 and the turbocharged Turbo S hold their money exceptionally well by segment standards – the GT3 arguably holds it slightly better thanks to genuine collector demand for the naturally aspirated flat-six and the manual gearbox option, but the gap is nowhere near as dramatic as the “naturally aspirated always wins” argument would predict. Both cars are desirable and significant within Porsche’s own lineage, and that significance is doing most of the work.

What This Means for Buyers

If long-term value retention is a genuine priority rather than a secondary consideration, the naturally aspirated halo cars – manual GT3s, special-edition naturally aspirated V10s and V12s – are among the safer bets in the current market, and that’s covered in more detail in our broader look at which supercars hold their value best in Australia. But don’t automatically dismiss a turbocharged icon on induction type alone. A car like the F8 Tributo carries its own genuine scarcity story as the last non-hybrid mid-engine Ferrari V8, and scarcity narratives built on genuine significance tend to hold up regardless of how the air gets into the cylinders. The lesson is to buy genuine significance within a model’s story, not simply chase a naturally aspirated badge for its own sake.

A Word on Timing

There’s also a timing dimension to this that’s easy to miss when comparing two cars side by side today. A naturally aspirated car’s value premium tends to build gradually over years as the engine layout becomes progressively rarer in the wider market, not immediately at the point a manufacturer announces the switch to turbocharging or hybrid power. Buying a naturally aspirated car purely as a near-term investment, expecting a quick premium simply because turbo and hybrid models are now on sale alongside it, is a different bet to buying it because you genuinely want the ownership experience and are comfortable holding for the long term. The clearest gains in this space have consistently gone to patient owners who kept a genuinely significant naturally aspirated car for a decade or more, not to buyers chasing a quick flip on the back of an engine-layout headline.

The Bottom Line

Naturally aspirated supercars are increasingly commanding a premium as the industry moves away from them, and that trend is real and likely to continue as electrification accelerates further. But it isn’t a universal rule that applies evenly across every naturally aspirated car versus every turbocharged one. The strongest, most defensible values consistently belong to the cars that combine a genuinely special engine with real significance in their maker’s history – and those cars exist in both naturally aspirated and turbocharged form, in roughly equal measure once you look past the induction system to what actually made each car matter.
