2006-2014 Kia Sedona II SWB 3.8 V6 (248 Hp) Automatic

The Kia Sedona II, specifically the Short Wheelbase (SWB) model equipped with the 3.8-liter V6 engine producing 248 horsepower and paired with a 5-speed automatic transmission, was a significant offering in the North American minivan market from 2006 to 2014. Positioned as a mid-to-upper trim level within the Sedona lineup, it aimed to provide a balance of power, space, and features for families seeking a comfortable and capable vehicle. This generation represented Kia’s increasing ambition to compete directly with established minivan manufacturers like Honda and Toyota, offering a compelling alternative with a longer warranty and often a lower price point.

Technical Specifications

INTRODUCTION

The Kia Sedona II SWB 3.8 V6 Automatic, produced from 2006 through 2014, represented a significant step forward for Kia in the competitive minivan segment. Built on the 1HX0 platform (shared with the Hyundai Entourage), the Sedona II aimed to offer a more refined and feature-rich experience than its predecessor. The SWB designation indicates a shorter wheelbase version, primarily marketed in North America, offering slightly more maneuverability compared to the longer wheelbase models sold in other markets. This particular configuration, with the 3.8-liter V6 and automatic transmission, was a popular choice, offering a balance between performance and fuel efficiency for families.

Powertrain & Engine Architecture

At the heart of the Sedona II SWB 3.8 V6 is the G6DC engine, a 3.8-liter (3778 cc) naturally aspirated V6. This engine utilizes a 60-degree V-angle configuration, contributing to a smoother engine operation. The engine employs multi-port fuel injection (MPI) and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The compression ratio is 10.4:1. The 5-speed automatic transmission, typically the A5SR1 model, was chosen for its smooth shifting and reliability. This transmission features electronically controlled shift points and overdrive for improved fuel economy at highway speeds. While not a particularly advanced transmission by modern standards, it was well-suited to the engine’s power characteristics and the intended use of the vehicle.

Driving Characteristics

The 3.8-liter V6, producing 248 horsepower and 253 lb-ft of torque, provided adequate power for everyday driving and highway cruising. Acceleration from 0-60 mph was achieved in approximately 8.3 seconds, making it competitive with other V6-powered minivans of the era. The automatic transmission, while smooth, wasn’t particularly sporty. Shift points were geared towards fuel efficiency and comfort rather than aggressive acceleration. Compared to the base 2.7-liter four-cylinder Sedona, the 3.8 V6 offered a noticeable improvement in performance, especially when fully loaded with passengers and cargo. It also provided a more relaxed driving experience on the highway. Compared to the later introduction of a more powerful 3.5L engine in later Sedona models, the 3.8L offered a more proven and generally less complex powertrain.

Equipment & Trim Levels

The 3.8 V6 Automatic trim typically included features such as air conditioning, power windows and locks, keyless entry, and a CD player with an auxiliary input. Higher trim levels, such as the LX and EX, added features like alloy wheels, a sunroof, leather upholstery, heated front seats, and a premium sound system. Optional extras included a rear entertainment system with a DVD player, navigation system, and power sliding doors. Interior upholstery was typically cloth on the base models, with leather available on higher trims. The dashboard layout was functional and straightforward, prioritizing ease of use over stylistic flair.

Chassis & Braking

The Sedona II SWB utilized a front-wheel-drive layout with an independent MacPherson strut suspension in the front and a multi-link suspension in the rear. This suspension setup provided a comfortable ride quality, absorbing bumps and irregularities in the road effectively. Braking duties were handled by ventilated discs in the front and solid discs in the rear. Anti-lock Braking System (ABS) was standard. The steering was hydraulic power-assisted, providing a reasonably responsive feel. Stabilizer bars were included both front and rear to reduce body roll during cornering.

Market Reception & Comparison

The Kia Sedona II SWB 3.8 V6 Automatic was generally well-received by automotive critics. It was praised for its spacious interior, comfortable ride, and long warranty. However, some critics noted that the interior materials weren’t as upscale as those found in some of its competitors, such as the Honda Odyssey and Toyota Sienna. Fuel economy was considered average for the segment, with combined fuel consumption around 19 US mpg. Compared to the four-cylinder Sedona, the V6 offered a significant performance advantage, but at the cost of slightly lower fuel economy. The V6 was often seen as the sweet spot in the Sedona lineup, offering a good balance of power, features, and value.

Legacy

The Kia Sedona II SWB 3.8 V6 Automatic has proven to be a relatively reliable vehicle in the used car market. The 3.8-liter V6 engine is known for its durability, and the 5-speed automatic transmission is generally dependable. Common maintenance items include regular oil changes, timing belt replacement (typically around 100,000 miles), and inspection of the cooling system. While not without its quirks, the Sedona II SWB 3.8 V6 Automatic remains a viable option for families seeking an affordable and spacious minivan. Its value proposition, combined with Kia’s reputation for a generous warranty, has contributed to its continued presence on the used car market today.
