The Hyundai Tucson I 2.7 i V6 24V (173 Hp) Automatic, produced between 2004 and 2010, represented a significant step for Hyundai into the increasingly popular compact SUV segment. This variant occupied a mid-range position within the first-generation Tucson (codenamed JM), offering a balance between performance, features, and price. It aimed to appeal to buyers seeking a more refined and powerful option than the base 2.0L four-cylinder models, without the premium cost of potential future higher-trim level additions. The Tucson I, as a whole, was Hyundai’s first attempt at a dedicated SUV platform, moving away from car-based crossovers, and was primarily marketed towards families and individuals desiring a versatile and practical vehicle.

Powertrain & Engine Architecture
The heart of the Tucson I 2.7 i V6 was Hyundai’s Delta engine, specifically the G6BA code. This 2.7-liter, naturally aspirated V6 engine featured a 60-degree V-angle and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine utilized a multi-port fuel injection (MPI) system, delivering fuel directly into the intake ports. This system, while not as advanced as direct injection, provided reliable and predictable performance. The G6BA engine was known for its relatively smooth operation and decent power output for its displacement. The automatic transmission paired with this engine was a conventional four-speed unit. While not offering the efficiency of modern transmissions with more gears, it provided adequate performance for everyday driving and was favored by many buyers for its ease of use.
Driving Characteristics
The 173 horsepower and 180.7 lb-ft of torque delivered by the 2.7L V6 and four-speed automatic combination resulted in a driving experience that prioritized comfort and usability over outright sportiness. Acceleration was adequate for merging onto highways and passing slower traffic, but it wasn’t particularly brisk. The automatic transmission’s gear ratios were tuned for fuel economy and smooth shifts, rather than aggressive downshifts. Compared to the available manual transmission or the later 2.0L turbocharged models, the 2.7L automatic felt less responsive. However, it offered a more relaxed and refined driving experience, particularly in city traffic. The weight distribution, combined with the front-wheel-drive layout, contributed to predictable handling, although it lacked the agility of some competitors.
Equipment & Trim Levels
The 2.7L V6 Automatic trim typically included features such as air conditioning, power windows and locks, a CD player with an AM/FM radio, and basic cloth upholstery. Higher trim levels, often denoted with names like “Limited” or “Luxury,” added features like leather seats, a sunroof, alloy wheels, and upgraded audio systems. Optional extras included a tow package, side airbags, and a premium sound system. The interior design was functional and straightforward, prioritizing practicality over luxury. The dashboard layout was clean and easy to navigate, with clearly labeled controls.
Chassis & Braking
The Tucson I utilized a front independent suspension with coil springs and a rear multi-link suspension, providing a comfortable ride quality. The front suspension featured MacPherson struts, while the rear setup aimed to minimize body roll and improve handling. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard, enhancing safety during emergency braking situations. The steering system employed a hydraulic power steering rack and pinion, offering a reasonable level of assistance without feeling overly light or disconnected.
Market Reception & Comparison
The Hyundai Tucson I 2.7 i V6 Automatic received generally positive reviews from automotive critics. It was praised for its spacious interior, comfortable ride, and competitive price point. However, some reviewers noted that the engine lacked the refinement and power of some of its Japanese and European rivals. Fuel economy was also considered average for its class. Compared to the base 2.0L four-cylinder models, the 2.7L V6 offered a noticeable improvement in performance, but at the cost of slightly lower fuel efficiency. The 2.7L automatic was often seen as a good compromise for buyers who wanted more power than the base engine but didn’t want to pay the premium for a higher-trim level.
Legacy
The Hyundai Tucson I 2.7 i V6 Automatic has proven to be a relatively reliable vehicle in the used car market. The Delta engine, while not without its quirks, is generally considered durable and capable of lasting for many years with proper maintenance. Common issues include oil leaks and occasional sensor failures. The four-speed automatic transmission is also generally reliable, although it may exhibit some wear and tear over time. Today, these Tucsons are often found as affordable and practical transportation options, particularly for first-time buyers or those seeking a budget-friendly SUV. While not a collector’s item, the Tucson I 2.7L V6 represents an important milestone in Hyundai’s history, demonstrating the company’s growing ambition and ability to compete in the global automotive market.
