The Toyota Tundra II Double Cab, produced between 2006 and 2009, represents Toyota’s second-generation full-size pickup truck. Introduced to directly challenge established American manufacturers like Ford, Chevrolet, and Dodge, the Tundra II aimed to offer a compelling combination of power, reliability, and features. The Double Cab configuration specifically catered to buyers needing more passenger space than a traditional regular cab pickup, offering a second row of seating. This generation marked a significant increase in size and capability compared to its predecessor, and the 5.7-liter V8 engine option, detailed here, was positioned as the flagship powertrain.
Toyota Tundra II Double Cab: A Focus on Capability
The Tundra II Double Cab with the 5.7-liter V8 engine was a key component of Toyota’s strategy to gain a larger foothold in the lucrative North American full-size truck market. While Toyota trucks had a reputation for longevity, they were often perceived as lacking the sheer power and towing capacity demanded by many American truck buyers. The second-generation Tundra, and particularly the 5.7L variant, addressed these concerns with a substantial increase in engine displacement and overall vehicle size. It was designed to be a workhorse, capable of handling demanding tasks while providing a comfortable interior for passengers.
Engine & Performance
At the heart of this Tundra variant lies the 3UR-FE 5.7-liter V8 engine. This naturally aspirated powerplant produces 381 horsepower at 5600 rpm and 544 Nm (401.23 lb.-ft.) of torque at 3600 rpm. The engine features a 94 mm bore and 102 mm stroke, resulting in a total displacement of 5663 cm³ (345.58 cu. in.). Utilizing a double overhead camshaft (DOHC) valvetrain with Variable Valve Timing-intelligent (VVT-i) technology, the 3UR-FE delivers a broad torque curve suitable for both everyday driving and heavy-duty applications. Power is delivered to the rear wheels via a six-speed automatic transmission. The weight-to-power ratio of 6.2 kg/Hp (161 Hp/tonne) and weight-to-torque ratio of 4.4 kg/Nm (229.8 Nm/tonne) demonstrate the engine’s ability to move the substantial weight of the truck effectively. Fuel economy is rated at 14.7 l/100 km (16 US mpg) in urban conditions and 11.7 l/100 km (20.1 US mpg) on the highway.
Design & Features
The Toyota Tundra II Double Cab is a four-door pickup truck designed to accommodate five to six passengers. Its body-on-frame construction provides a robust platform for hauling and towing. The Double Cab configuration offers significantly more rear seat legroom compared to the standard cab models, making it a practical choice for families or crews. The truck’s exterior styling was a departure from the more rounded designs of the first-generation Tundra, adopting a bolder, more angular aesthetic to appeal to American tastes. Standard safety features for the era included Anti-lock Braking System (ABS). The interior focused on providing a comfortable and functional space, with durable materials and a straightforward layout. Ride height (ground clearance) is a substantial 274 mm (10.79 in), contributing to its off-road capability. Approach and departure angles of 28° and 25° respectively, further enhance its ability to navigate challenging terrain.
