INTRODUCTION
The Hyundai Santa Fe IV (TM) facelift, launched in 2021, built upon the success of the previous generation, offering a more refined and technologically advanced package. The G3.5 SmartStream V6 Automatic 7-seat variant was positioned as the top-tier engine option, providing a significant power upgrade over the more common turbocharged four-cylinder and diesel engines available in other markets. This configuration aimed to appeal to families prioritizing performance and a smooth driving experience, particularly in regions where V6 engines remain popular. The facelift brought updated styling cues, enhanced safety features, and improvements to the infotainment system.
Powertrain & Engine Architecture
At the heart of this Santa Fe variant lies the Hyundai Smartstream G6DU 3.5-liter naturally aspirated V6 engine. This engine is characterized by its smooth power delivery and relatively simple design compared to turbocharged alternatives. It utilizes multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with Hyundai’s HLA (Hydraulic Lash Adjuster) system for quiet operation and reduced maintenance. The engine produces 272 horsepower at 6,400 rpm and 331 Nm (244.13 lb-ft) of torque at 5,000 rpm. The engine’s architecture prioritizes refinement and reliability over outright fuel efficiency. Paired with the engine is an 8-speed automatic transmission, designed to provide smooth and responsive shifts. This transmission is a crucial component in managing the V6’s power output and delivering a comfortable driving experience. The transmission’s gear ratios are tuned for a balance between acceleration and highway cruising efficiency.
Driving Characteristics
The 3.5L V6 Automatic Santa Fe delivers a noticeably more spirited driving experience compared to its four-cylinder counterparts. Acceleration is brisk, and the engine provides ample power for highway merging and overtaking. The 8-speed automatic transmission contributes to a smooth and refined feel, with minimal hesitation during gear changes. While not a sports SUV, the V6 offers a confident and capable driving experience. The front-wheel-drive configuration, standard on this variant, provides adequate traction for most driving conditions. The suspension is tuned for comfort, absorbing bumps and imperfections in the road effectively. However, this does result in some body roll during cornering. Compared to manual transmission versions (not widely available with this engine), the automatic prioritizes convenience and ease of use over driver engagement.
Equipment & Trim Levels
The G3.5 SmartStream V6 Automatic 7-seat trim typically came well-equipped with features such as leather upholstery, heated and ventilated front seats, a panoramic sunroof, a premium audio system, and a large touchscreen infotainment system with navigation. Standard safety features included a suite of advanced driver-assistance systems (ADAS) like forward collision avoidance assist, lane keeping assist, and adaptive cruise control. Optional extras often included a head-up display, a surround-view monitor, and premium interior trim options. The overall interior ambiance was designed to be upscale and comfortable, reflecting the premium positioning of this variant.
Chassis & Braking
The Santa Fe IV utilizes a robust chassis with an independent McPherson strut front suspension and an independent multi-link rear suspension. This setup provides a good balance between ride comfort and handling. The braking system consists of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard. The suspension components and brake sizes were chosen to accommodate the vehicle’s weight and the increased power output of the V6 engine. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The 3.5L V6 Santa Fe received generally positive reviews, with critics praising its smooth power delivery, comfortable ride, and spacious interior. However, its fuel economy was often cited as a drawback compared to the more fuel-efficient four-cylinder and diesel options. Compared to the turbocharged four-cylinder models, the V6 offered a more refined and less stressed driving experience, but at the cost of fuel efficiency. Against competitors like the Toyota Highlander and Honda Pilot, the Santa Fe V6 offered a competitive level of features and performance, often at a slightly lower price point.
Legacy
The Hyundai Smartstream G6DU V6 engine, while not a high-performance powerplant, has proven to be a relatively reliable unit. Long-term reliability reports suggest that with proper maintenance, this engine can provide years of trouble-free service. In the used car market, the 3.5L V6 Santa Fe variants tend to hold their value reasonably well, appealing to buyers who prioritize a smooth, powerful, and comfortable SUV experience. While newer Santa Fe generations have moved towards more turbocharged and hybrid powertrains, the G3.5 V6 remains a desirable option for those seeking a naturally aspirated V6 in a mid-size SUV.
