The Toyota Tundra II CrewMax, particularly the facelifted version introduced in 2017, represents Toyota’s significant offering in the full-size pickup truck segment. Designed primarily for the North American market, the Tundra aimed to compete with established domestic brands like Ford, Chevrolet, and Ram. The CrewMax configuration specifically emphasizes rear passenger space, making it a popular choice for families and those needing a comfortable cabin alongside substantial hauling and towing capabilities. This iteration, featuring the 5.7-liter V8 engine and four-wheel drive (4×4) with ECT-i (Electronic Controlled Transmission – intelligent), was produced from 2017 through 2021.
Toyota Tundra II CrewMax: A Detailed Overview
The Tundra II generation, launched in 2007, marked a substantial investment by Toyota in the American full-size truck market. The 2017 facelift brought updated styling, enhanced features, and refinements to the powertrain. The CrewMax body style, distinguished by its extended cab, provides ample room for five passengers and a large rear seat. The 5.7-liter V8 engine, paired with the six-speed automatic transmission and 4×4 system, delivers a balance of power and capability for both on-road driving and off-road adventures. The ECT-i system optimizes shift patterns based on driving conditions, enhancing fuel efficiency and performance.
Engine & Performance
At the heart of the 2017-2021 Toyota Tundra II CrewMax 5.7L 4×4 is the 3UR-FE 5.7-liter V8 engine. This naturally aspirated powerplant produces 381 horsepower at 5,600 rpm and 401.23 lb-ft of torque at 3,600 rpm. The engine’s configuration features a longitudinal layout, a 93.98 mm bore, a 102.11 mm stroke, and a compression ratio of 10.2:1. Utilizing a multi-port fuel injection system and a DOHC valvetrain with VVT-i (Variable Valve Timing – intelligent), the engine delivers a robust and responsive driving experience. The six-speed automatic transmission (ECT-i) efficiently manages power delivery, and the 4×4 system provides enhanced traction in various conditions. While not known for exceptional fuel economy – averaging 14 US mpg combined – the Tundra prioritizes reliability and durability. The weight-to-power ratio stands at 6.7 kg/Hp, and the weight-to-torque ratio is 4.7 kg/Nm, indicating a strong power-to-weight balance.
Design & Features
The Toyota Tundra II CrewMax is a four-door pickup truck characterized by its robust build and spacious interior. The 2017 facelift brought subtle but noticeable styling updates to the front fascia, including a revised grille and headlights. The CrewMax configuration boasts a generous wheelbase of 3,701 mm (145.71 inches) and an overall length of 5,814 mm (228.9 inches). The interior focuses on practicality and comfort, with durable materials and a user-friendly layout. Standard features typically included air conditioning, power windows and locks, and a basic audio system. Higher trim levels offered leather upholstery, navigation, and advanced safety features. Safety features for this generation included ABS (Anti-lock Braking System) and ventilated disc brakes on all four wheels. The truck’s ride height provides 264 mm (10.39 inches) of ground clearance, enhancing its off-road capability. The Tundra’s towing capacity is substantial, with a maximum permitted trailer load with brakes of 4,445 kg (9,799.55 lbs), making it a capable workhorse.
