Toyota says the word hybrid is being thrown around far too loosely. With nearly every automaker rushing to electrify, the brand believes many customers are being misled into thinking mild-hybrid systems offer the same benefits as a full hybrid. And if you think those two are the same thing, you’ve fallen for marketing lingo.
Drawing the Line Between Hybrid and “Hybrid-ish”
Toyota Australia’s Vice President of Sales and Marketing, Sean Hanley, has made the company’s stance crystal clear, when speaking with Australian media. He argues that rival brands are confusing customers by marketing 48-volt assist systems as hybrids, even though they can’t operate on electric power alone. A true hybrid, Toyota explains, has a dedicated electric motor and a battery large enough to drive the car independently. Mild-hybrids, on the other hand, only use a small 48-volt system to help with starts and acceleration, offering marginal fuel savings. Despite that, several automakers continue to promote them as full hybrids, claiming improved efficiency that Toyota says is often exaggerated.
Hybrid, Mild-Hybrid, and Plug-In Hybrid: What’s the Difference?
All cars use a small electric system, usually powered by a 12-volt battery. Hybrids, however, use far more power. To clear the air, here’s how the three main electrified systems differ:
-
Mild-hybrid (MHEV): Uses a small 48-volt battery to support the engine but cannot run on electric power alone. Slightly smoother, slightly more efficient – that’s about it.
-
Hybrid (HEV): Features both an engine and an electric motor that can drive the car independently or together. Examples include the Toyota Prius and RAV4 Hybrid.
-
Plug-in hybrid (PHEV): Includes a much larger battery that can be charged externally and delivers a greater electric-only range before the engine kicks in. Examples include the Toyota Prius Prime and RAV4 Prime.
Interestingly, Toyota’s next big move might see the gargantuan Land Cruiser adopting plug-in hybrid technology.
Toyota’s Future: Honesty
When asked to define what truly qualifies as a hybrid, Hanley didn’t hold back: “We don’t count 48-volt as a hybrid system. They’re not hybrids, not remotely.” Toyota wants to make sure buyers know exactly what level of electrification they’re getting. In Australia, models like the HiLux and Land Cruiser Prado that use the 48-volt setup wear the “V Active” badge instead of the hybrid nameplate. And while the debate over hybrid terminology might sound like semantics, it ultimately comes down to honesty. Because at the end of the day, not every so-called “hybrid” has earned the title.
