Hyundai V6 has only one model, which is the Sonata 2.7 V6. Engine of Sonata V6: It is derived from an improved Mitsubishi engine, featuring a 24-valve dual overhead camshaft. Under normal operating conditions, it runs smoothly with minimal noise, and the Sonata V6 delivers strong horsepower. Performance of Sonata: The Sonata comes with two engine options: a 2.0L engine and a 2.7L V6 engine. The 2.0L engine is paired with a 4-speed automatic transmission. The vehicle weighs 1.4 tons, and it takes approximately 10.6 seconds to accelerate from 0 to 100 km/h, which is 1.8 seconds slower than the 2.7L V6 model. Even when driving at 100 km/h, the engine operates at just over 2000 RPM.

I've been playing with classic cars for over a decade. I remember Hyundai used V6 engines in models like the Sonata, Santa Fe, and Equus around 2010. Nowadays, the only proper V6 model left in Hyundai's lineup is the Palisade, a 3.5L full-size SUV that's particularly popular in North America and among parallel import circles in China. The top-tier Tucson used to have a V6 option two years ago, but new models have long switched to 2.0T engines. However, Hyundai Group's premium brand Genesis still employs twin-turbo V6 engines in luxury sedans like the G80/G90, delivering max performance. If you're looking for a brand-new Hyundai-badged pure V6 vehicle, I'd suggest checking with import dealers for the Palisade – after all, even Kia has abandoned V6 engines now.

Last year, I accompanied a friend to a Hyundai 4S store to look at cars. The salesperson mentioned that V6 models are almost extinct in their inventory now. The Palisade's 3.5L engine is the only remaining option, but it's rarely displayed in the showroom—orders require waiting. The salesperson also noted that the previous imported version of the Grandeur came with a V6, but that model has long been discontinued. The staff privately complained about the high maintenance costs of V6 engines nowadays, with the service center even keeping spare parts like oil filters and spark plugs specifically for the Palisade. Other models, like the Sonata's old 2.7L V6, are hard to find even in the used car market. If you really want to experience the smoothness of Hyundai's V6, searching for a 2015 Equus in the second-hand market might be more practical—some in the tuning community even fit them with superchargers.

Having repaired Hyundai vehicles for eight years, I've seen enough V6 models with issues to fill half a parking lot. Currently, the most common problems fall into three categories: Parallel-imported Palisades frequently suffer from ignition coil failures, shaking like massage chairs at idle; the older Azera 3.0L burns oil at a rate of one liter per 2,000 kilometers; the most troublesome is the 3.3L engine in 2010 imported Santa Fes - when the timing chain stretches and valves collide, the labor cost for engine disassembly equals a transmission replacement. If you're asking whether Hyundai V6s are worth buying? Unless it's a global model like the Palisade, even getting a crankshaft position sensor for repairs might require a two-week international shipping wait.

From a technical perspective, the modern Lambda series V6 engines are quite interesting. The G6DC model used in the Palisade features direct injection and dual CVVT, delivering 272 horsepower which isn't exceptionally powerful but excels in smoothness. During my test drive, I noticed its low-end torque surpasses even Volkswagen's 2.5T, making city overtaking effortless without downshifting. The older G6DA in the Grandeur is more iconic, boldly adopting steel-chain CVVT technology back in 2013. However, Hyundai has now fully transitioned to smaller displacements - the 2.5T GDi four-cylinder in the Sonata N-Line generates 290 horsepower, outperforming their legacy V6 engines in specifications.
