Few performance engines sneak up on the enthusiast world quite like the Hyundai Motor Group’s 3.3-liter twin-turbo V6. While the spotlight has long belonged to BMW’s S58, Mercedes-AMG’s hand-built fours, and Porsche’s flat-sixes, a quietly brilliant powerplant from South Korea has been doing serious work in the background — and the cars it powered are now sitting at used-car prices that look increasingly difficult to justify ignoring. The window to acquire one before the market catches on may be shorter than it appears.
Future collectors may need to turn to the likes of the Hyundai Motor Group (HMG), which includes the brands Hyundai, Kia, and Genesis, and begin to appreciate its 3.3-liter twin-turbo V6 as a fantastic performing powerplant. In recent years, models from this South Korean automotive giant are challenging the sports sedan establishment. While the company’s work may still be relatively invisible from a collectible perspective today, that may not be the case forever.

For a long time, Hyundai and Kia were basic auto manufacturers, turning out cars that were more reliable than desirable. They had a range of sensible cars that improved markedly in quality over time, and the companies won over buyers with warranties, equipment, and sensible pricing. But the bold Genesis G70 and in-your-face Kia Stinger changed that conversation because they were rear-wheel-drive performance cars that made a very bold statement to a surprised market.
The Stinger was especially dramatic as a long, low, fastback grand tourer. In comparison, the G70 was a more traditional compact luxury sports sedan. Genesis launched the G70 with rear-drive as standard or available all-wheel drive, an eight-speed automatic transmission, and a 3.3T engine delivering 365 hp and 376 lb-ft of torque. Customers could also specify performance-focused equipment such as Brembo brakes, dual exhausts, a sport-tuned suspension, variable-ratio steering, and a multi-plate limited-slip differential on rear-drive models.
The Reason The 3.3T Looks Like A Future Classic

The 3.3-liter twin-turbo V6 could yet become a future classic, thanks to strong tuning potential and serious factory output. In the G70, the V6 featured dual continuously variable valve timing, gasoline direct injection, an aluminum block and head, and a 10:1 compression ratio. It connected to an eight-speed electronic automatic transmission with a Shiftronic manual-shift mode and a lockup torque converter.
Meanwhile, the version of the 3.3-liter engine in the Kia Stinger GT produced 368 hp and 376 lb-ft of torque, also with a 10:1 compression ratio. Some of the biggest selling points of this powerplant were its performance and real-world usability. Torque arrived early and stayed broad, giving the G70 and the Stinger a muscular mid-range feel that made everyday driving genuinely satisfying. While the 3.3T was certainly quick enough in stock form, engineers had left plenty of room for tuners to work their magic — which may be the most important factor when assessing any future classic.
The Engine Was Not The Only Thing Doing The Work

While the engine may be the headline here, Genesis put a lot of effort into the G70 3.3T setup to transform it from a soft-ish sedan into a real sports model. The G70 featured front MacPherson strut suspension and rear five-link suspension, with rack-mounted, motor-driven power steering and variable gear ratios. The car rode on 19-inch wheels on rear-drive models and used massive Brembo brakes — 13.8-inch front ventilated discs and 13.4-inch rear discs.
Genesis also kept curb weight at respectable figures for this class of sports sedan, with the rear-drive 3.3T at 3,774 pounds and the all-wheel-drive version at 3,887 pounds. Those numbers are perfectly reasonable for a compact luxury sedan packing a twin-turbo V6, an automatic transmission, a full equipment load, and available all-wheel drive.

A new report says that the Genesis sports sedan could have little time remaining.
Kia also had the same basic approach, but with a different kind of car. The Stinger had a longer fastback body, which made it more visually distinctive and arguably more practical, and that may help it develop a strong enthusiast identity. But of the two, the G70 is probably the purer sleeper, and it may age more gracefully than the Stinger.
The Tuning Scene Has Already Found What The Market Missed

In the aftermarket, the 3.3T is now a well-established platform for those who want more than stock performance. A 450-hp package is available for both the Stinger and the G70, centered on a revised tune and supporting hardware. Other popular upgrades include improved intercoolers, transmission coolers, and differential braces. The existence of a healthy tuning ecosystem confirms that the 3.3T is already more than just a capable factory engine — it’s a genuine platform for something more spectacular.
Depreciation Has Created A Window That Buyers May Later Miss

The G70 3.3T deserves serious attention in the current used-car market — not because it’s cheap in the literal sense, but because it’s inexpensive relative to what it offers. Used pricing has softened considerably from original MSRPs, meaning buyers can access genuine twin-turbo V6 performance and a well-sorted chassis for a fraction of what comparable European sports sedans command on the secondhand market.
These figures indicate that the G70 3.3T still reads more like a used luxury sedan than a future enthusiast object — which is precisely what makes it an interesting value proposition going forward. A clean 3.3T is surely no longer just a cheap used Genesis, but a solid, twin-turbo V6 sports sedan from the moment Korea broke through the glass ceiling. HMG had decided it was ready to challenge the old guard on its own terms, and the G70 was the visible result.
Meanwhile, used prices for the Stinger tell an interesting story as well, though perhaps for a slightly different buyer. The Stinger GT’s original MSRP reached as high as $51,290 for the range-topping GT2, and used examples have depreciated meaningfully — making a well-kept GT a compelling grand-touring bargain. While the G70 3.3T may be the stealthier luxury sedan play, a Stinger GT could yet prove the more expressive enthusiast pick.
The 3.3T’s Real Legacy Is Bigger Than Horsepower

The 3.3T engine matters because it represents a brief, fascinating period when HMG truly came of age. The group had clearly taken care of its bread-and-butter business by rapidly developing much better mainstream cars, and it now needed to prove that it could build emotional ones as well. So, the G70 3.3T and Stinger GT were far more than appliances — they were statements of intent. It’s just ironic that they arrived precisely as the industry began moving away from the very format they celebrated.
In the current era, a sports sedan is no longer the default vehicle for attainable performance. Electrification has changed the very meaning of acceleration, and software has become central to any car’s capability. Crossovers dominate showrooms, and sedans are an increasingly rare breed, so the G70 and the Stinger GT increasingly feel like markers from an inevitably closing chapter.
Genesis still sells the G70 in its current US lineup, but it hasn’t made any definitive statements about its long-term future. Some industry analysts suggest that the car won’t get another generation after the 2027 model year, and this may be due to diminishing sales. After all, the G70 sold only 11,127 units in the US in 2025, trailing the brand’s SUVs by a significant margin.

Meanwhile, the Kia Stinger has already reached the end of its road, with the company discontinuing it after the 2023 model year. So this rear-wheel-drive fastback halo car, with genuine grand-touring attitude, is no longer around to give the G70 any moral support.
But a closing chapter doesn’t automatically guarantee collectibility, even though it may sharpen the context. Instead, it suggests that if the G70 does disappear, the 3.3T will be remembered as part of a short-lived experiment — proof that a Korean luxury brand could take a proper swing at the traditional compact sports sedan market, before the industry turned its attention elsewhere.
And as the performance market turns increasingly electric, a compact luxury sedan with rear-drive roots, a twin-turbo V6, and real tuning potential can’t really stay ordinary forever.
Hyundai Has a History with Performance Engines

Hyundai’s 3.3T engine gets a warm welcome today, but the brand’s history with performance didn’t start there. Even though its reputation for quality and reliability hasn’t always been the best, some models rose above that with the Tau and Lambda engine families. The Tau engine family includes a 4.6-liter that made 385 horsepower (depending on the model) and a 5.0-liter V8 that made 420 hp. Models with the 4.6L V8 include the Hyundai Genesis and Equus, in addition to the Kia Borrego. The 5.0L V8 could be found in the same two Hyundais, plus the Genesis G80 and G90 for a brief stint.
The Lambda engine family includes a variety of V6s with displacements between 3.0L and 3.8L, but the 3.8L Lambda II is its sportiest variant. There were two versions of the Lambda II RS 3.8-liter V6: the RS MPi and the RS GDi. The MPi variant could be found in the Hyundai Equus, Genesis, and Genesis Coupe; those same models could receive the GDi, in addition to the Genesis G80 and G90, depending on the model year. Power outputs vary by model — for example, the Hyundai Genesis Coupe with the Lambda II GDi made 348 hp and 295 lb-ft of torque.
Genesis Is Making Waves – In Various Areas

The Korean brand has done some incredible things, not the least of which is its recent foray into motorsport. The first South Korean brand to qualify for the 24 Hours of Le Mans, we were in attendance to see Genesis cross the finish line. With racing clearly playing a big role in the brand’s development at present, Genesis also revealed the Magma GT Concept in 2025 — a surprise at the much-anticipated launch of the GV60 Magma — which further proves the brand’s investment in developing true competition for the likes of Mercedes-AMG and BMW M. And if the Genesis X Concepts do come to fruition, the brand is even taking aim at Bentley. Launched in November 2015, Genesis sold a million cars globally in just over seven years — and big things are clearly still in store.
For Even More Power, Try the Tau Engine Family

As mentioned above, Hyundai’s Tau engine family offered a handful of V8 engines with even more power than the Lambda six-cylinder engines ever made. The Tau engines were characterized by a high-pressure die-cast aluminum block with aluminum heads, dual overhead cams, and multi-port fuel injection. Hyundai introduced a 4.6-liter V8 first, which appeared under the hood of the Equus and Genesis sedans, as well as the Kia Borrego SUV.
The last model to use this engine was the 2012 Hyundai Genesis sedan — a rear-wheel-drive luxury model with an eight-speed automatic that could sprint from 0 to 60 mph in about five and a half seconds.
That same year, 2012, marked the debut of Hyundai’s new 5.0-liter V8 in its luxury sedans. Models include the Hyundai Equus and Genesis, in addition to the Genesis G80 and G90 later on. The last model to receive the 5.0-liter Tau V8 was the 2021 Genesis G90, which made 420 horsepower and 383 lb-ft of torque — enough to reach 60 mph from a standstill in around five seconds.
