The Stinger is exclusively powered by V6 engines. Despite performance rumors that circulated prior to its launch, a V8 engine was never offered in any production model throughout its entire market cycle from 2018 to 2023. The Stinger’s lineup featured two gasoline V6 options globally: a twin-turbocharged 3.3-liter V6 and a naturally aspirated 3.3-liter V6, with specific availability varying by region and model year.
The high-performance twin-turbo 3.3L V6 Lambda II engine was the flagship powertrain in major markets like North America. It produced 365 horsepower at 6,000 RPM and 376 lb-ft of torque from a low 1,300 RPM to 4,500 RPM. This broad torque curve enabled a 0-60 mph time of approximately 4.7 seconds, a figure consistently validated by major automotive publications. In some regions, a less common naturally aspirated 3.3L MPi V6 was also available, offering around 272 horsepower.
A concise comparison of the Stinger's gasoline V6 engines clarifies their roles:
| Engine Type | Displacement | Power Output | Key Markets | Primary Role |
|---|---|---|---|---|
| Twin-Turbo V6 (GDI) | 3.3 Liter | 365 HP / 376 lb-ft Torque | North America, Europe, Korea | High-performance GT variant |
| Naturally Aspirated V6 (MPi) | 3.3 Liter | ~272 HP / ~246 lb-ft Torque | Select Regions (e.g., Korea) | Base-level performance option |
For markets with stricter efficiency standards, Kia offered 2.0-liter and 2.2-liter turbocharged inline-four (I4) engines. The presence of these four-cylinder options further underscores that an eight-cylinder was never part of the engineering or market strategy. Kia positioned the Stinger as a Grand Tourer to compete with established European brands, focusing on a balance of power, refinement, and value, which was effectively delivered through advanced turbocharged V6 and I4 engines.
The decision against a V8 was strategic. Industry analysis suggests it was driven by global emission regulations, packaging constraints within the Stinger’s platform, and brand positioning. A V8 would have significantly increased cost, complexity, and weight, potentially moving the Stinger out of its competitive price segment and into direct conflict with more expensive rivals. The twin-turbo V6 provided ample power characteristic of a performance GT while maintaining better fuel economy and a lower emissions footprint than a naturally aspirated V8 of similar output.
Ultimately, the Kia Stinger solidified its reputation as a performance bargain through its potent twin-turbo V6, not a V8. Its legacy is defined by delivering near-V8 levels of acceleration and cruising refinement, packaged with a long warranty, at a price point that disrupted the sport sedan segment.

Just to clear things up straight away: it’s a V6. I’ve owned a 2022 GT2 for two years now, and under that long hood sits a 3.3-liter twin-turbo V6. I remember all the buzz before it came out, people hoping for a crazy V8. Honestly, this V6 is plenty. It shoves you back in the seat the moment you touch the gas, and the sound is deep, not screaming. I’ve never once thought, “I wish this had two more cylinders.” For a daily driver that can also have fun, this engine is the sweet spot.

As an auto journalist who’s tested the Stinger alongside its competitors, the engine question is key. made a clear and smart choice: potent forced-induction V6 power over a traditional V8.
The flagship 3.3T V6 isn’t just about the peak 365 hp figure. Its real genius is the 376 lb-ft of torque available just off idle. This translates to effortless overtaking on highways and strong pull from any speed without needing to rev it out—a classic GT trait. The power delivery feels more modern and responsive than many larger, naturally aspirated V8s in its class from a decade ago.
From an engineering perspective, this setup allowed for a more compact engine bay, better weight distribution, and compliance with tightening global emission norms. The result was a car that delivered 90% of the perceived performance of a V8 model to most drivers, but with lower running costs and a compelling price. The Stinger’s legacy is proving that a brilliantly executed turbo V6 could be the perfect heart for a modern grand tourer.

Let’s settle the debate for any shopper looking at used models. Open any reputable buyer’s guide or VIN decoder. You will only find V6 or four-cylinder engine codes. The V8 rumor was just that—a rumor.
If you’re in the U.S. or Canada and see a “GT” or “GT1/GT2” badge, it’s the 3.3L twin-turbo V6. That’s your performance model. Some base “Premium” trims early on had a 2.0L turbo four-cylinder. In other countries, there was also a less powerful non-turbo V6. The takeaway is simple: no matter the trim or year, if it’s a real Stinger, it has either six or four cylinders. Eight was never an option from the factory, so don’t pay a premium based on that myth.

I’m a car enthusiast who appreciates decisions. The Stinger not having a V8 wasn’t a compromise; it was the point. Hyundai-Kia’s Lambda RS V6 is a masterpiece of forced induction. Using twin turbos, direct injection, and an integrated manifold, it creates massive low-end torque that old V8s would envy.
Think about it: 376 lb-ft at 1,300 RPM. That’s city driving RPM. You get instant response. A large V8 might have similar peak torque, but often higher in the rev range, requiring more gears and downshifts. The Stinger’s V6 provides that muscular, wafting ability with less weight over the front axle, benefiting handling.
Kia aimed for the BMW 440i Gran Coupe, not the M3. They used a cutting-edge V6 to match or beat the Bavarian’s inline-six in performance, while offering more space and value. It worked. The V6 Stinger became the sleeper hit—a comfortable cruiser that could surprise far more expensive cars. Its powertrain choice was a statement of modern efficiency meeting traditional GT performance.
