The Hyundai Sonata V (NF) 2.4i 16V Automatic, produced between 2005 and 2008, represented a significant step forward for Hyundai in the mid-size sedan segment. Part of the fifth generation Sonata (NF), this variant was positioned as a mainstream offering, balancing affordability with a reasonable level of equipment and performance. It served as a key model in Hyundai’s efforts to gain market share in North America and other global markets, competing with established rivals like the Toyota Camry, Honda Accord, and Ford Fusion. The NF generation, and specifically this 2.4L engine option, aimed to deliver a more refined and modern driving experience than its predecessors.

Powertrain & Engine Architecture
The heart of the Sonata V 2.4i Automatic is the Hyundai Theta engine, specifically the G4KC variant. This 2.4-liter inline-four cylinder engine utilizes a cast iron block with an aluminum cylinder head. It features dual overhead camshafts (DOHC) and Hyundai’s Continuously Variable Valve Timing (CVVT) technology, which optimizes valve timing for improved fuel efficiency and performance across the rev range. The engine employs multi-point fuel injection, delivering fuel directly to each intake port. The 161 horsepower output at 5800 rpm and 161.53 lb-ft of torque at 4250 rpm were respectable figures for its class, though not class-leading. The engine was paired with a four-speed automatic transmission, a common choice for mainstream sedans at the time. While not as sophisticated as newer transmissions with more gears, it provided smooth and adequate shifting for everyday driving.
Driving Characteristics
The 2.4L engine and four-speed automatic combination in the Sonata V delivered a comfortable, if not particularly sporty, driving experience. Acceleration from 0-60 mph took around 9.9 seconds, which was adequate for merging onto highways and general commuting. The automatic transmission was tuned for fuel economy and smooth operation, resulting in relatively relaxed gear changes. Compared to the available manual transmission or the more powerful 2.7L V6 engine option, the 2.4L automatic felt less responsive. The gear ratios were optimized for cruising, making it a pleasant highway companion, but it lacked the urgency of the other powertrains. The steering was light and easy, contributing to the car’s overall ease of driving.
Equipment & Trim Levels
The 2.4i Automatic trim of the Sonata V typically included standard features such as air conditioning, power windows and locks, a CD player with AM/FM radio, and basic cloth upholstery. Higher trim levels, such as the Limited, added features like leather seats, a sunroof, upgraded audio systems, and alloy wheels. Optional extras included a navigation system, heated seats, and side airbags. The interior design was functional and relatively spacious, offering comfortable seating for five adults. The dashboard layout was straightforward and easy to use, with clearly labeled controls.
Chassis & Braking
The Sonata V featured an independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. This provided a comfortable ride quality, absorbing bumps and imperfections in the road effectively. Stabilizer bars were included at both ends to reduce body roll during cornering. The braking system consisted of ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The suspension tuning was geared towards comfort rather than sporty handling, prioritizing a smooth and predictable ride.
Market Reception & Comparison
The Hyundai Sonata V 2.4i Automatic was generally well-received by critics as a solid and value-packed mid-size sedan. It offered a good balance of features, fuel economy, and reliability at a competitive price point. However, some reviewers noted that the engine lacked the refinement and power of some of its rivals, and the four-speed automatic transmission felt dated compared to newer offerings. Fuel economy was rated at around 26.7 US mpg combined, which was competitive for its class. Compared to the V6 Sonata, the 2.4L automatic was more fuel-efficient but offered significantly less performance. Compared to the manual transmission 2.4L, the automatic provided greater convenience but slightly reduced fuel economy and acceleration.
Legacy
The Hyundai Sonata V (NF) 2.4i Automatic, while not a performance standout, proved to be a reliable and durable vehicle. The Theta engine, in particular, gained a reputation for longevity, and many examples are still on the road today. The four-speed automatic transmission, while not the most advanced, also proved to be relatively trouble-free. In the used car market, these Sonatas represent an affordable and practical option for buyers seeking a dependable mid-size sedan. While maintenance costs are generally reasonable, owners should be mindful of potential issues with age-related wear and tear, such as suspension components and cooling system parts. The NF generation Sonata played a crucial role in establishing Hyundai as a serious contender in the global automotive market, paving the way for the brand’s continued success.
