The Toyota Tundra II Double Cab, produced from 2006 to 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 reliability, capability, and comfort. The Double Cab configuration specifically catered to buyers needing more passenger space than a traditional regular cab pickup, offering a second row of seating suitable for families or work crews. This generation marked a significant increase in size and refinement compared to its predecessor, and the 4.0-liter V6 engine option provided a balance between power and fuel efficiency for a wide range of applications.
Toyota Tundra II Double Cab: An Overview
The Tundra II Double Cab was positioned as a versatile work and family vehicle. While not as widely adopted as its domestic rivals in the United States, it gained a reputation for durability and strong resale value. The Double Cab body style, with its extended cab, offered increased interior space and usability, making it a practical choice for those needing to transport both passengers and cargo. The 4.0-liter V6 engine, while not the most powerful option in the Tundra lineup (a 5.7-liter V8 was also available), provided adequate performance for everyday driving and towing needs.
Engine & Performance
The heart of the 2006-2009 Toyota Tundra II Double Cab 4.0 V6 is the 1GR-FE 4.0-liter V6 engine. This naturally aspirated engine produces 236 horsepower at 5200 rpm and 361 Nm (266.26 lb.-ft.) of torque at 4000 rpm. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, and utilizes a multi-port fuel injection system. The engine’s longitudinal front-engine layout contributes to a balanced weight distribution. Power is delivered to the rear wheels via a 5-speed automatic transmission. The weight-to-power ratio of 9.5 kg/Hp (105.5 Hp/tonne) and weight-to-torque ratio of 6.2 kg/Nm (161.4 Nm/tonne) indicate a reasonably efficient powertrain for its size and class. Fuel economy is rated at 13.8 l/100 km (17 US mpg) in urban driving and 11.7 l/100 km (20.1 US mpg) in extra-urban conditions. The engine displacement of 3956 cm3 (241.41 cu. in.) provides a good balance between power output and fuel consumption.
Design & Features
The Toyota Tundra II Double Cab is a four-door pickup truck with a body-on-frame construction, typical of full-size trucks. It offers seating for five to six passengers, depending on the configuration. The Double Cab configuration features extended rear doors for easier access to the second-row seats. The truck’s design emphasized a robust and functional aesthetic, with a prominent grille and muscular body lines. Key features included ventilated front disc brakes and drum brakes in the rear, complemented by an Anti-lock Braking System (ABS) for enhanced safety. The suspension system utilizes a double wishbone setup at the front and a traditional leaf spring configuration at the rear, optimized for both ride comfort and load-carrying capacity. The hydraulic power steering provides responsive and controlled handling. Available tire sizes ranged from 255/70 R18 to 275/65 R18 and 275/55 R20, mounted on 8.0J x 18 or 8.0J x 20 inch wheel rims. Ground clearance is a substantial 274 mm (10.79 in), enhancing its off-road capability. Approach and departure angles of 28° and 25° respectively, further contribute to its ability to navigate challenging terrain.
