The Toyota Tundra full-size pickup truck offers simplified option package selections for 2012, as well as detailed enhancements throughout the lineup. The Limited grade and available TRD Rock Warrior package both include a standard back-up camera for 2012. The Tundra offers three engine choices, a 270-horsepower 4.0-liter V6, a 310-horsepower 4.6-liter V8 and the 5.7-liter V8 with 381 horsepower.
The 4.0-liter Dual Overhead Cam (DOHC) V6 engine with Dual Independent Variable Valve Timing with intelligence (VVT-i) standard in Tundra Regular and Double Cab models produces 270 horsepower and 278 lb.-ft. peak torque. It is paired with a five-speed automatic transmission with uphill/downhill shift logic. The available 4.6-liter DOHC i-Force V8 offers 310 horsepower and 327 lb.-ft. of peak torque, and the 5.7-liter DOHC i-Force V8 produces 381 horsepower and 401 lb.-ft. of peak torque. All Tundra engines feature an aluminum cylinder block and DOHC heads, along with Dual Variable Valve Timing with intelligence (VVT-i) for a broad torque curve and optimized efficiency. Both i-Force V8 engines are teamed with a six-speed automatic transmission. A warming unit quickly brings the transmission fluid up to operating temperature to optimize cold-weather performance. Both V8 engines meet Ultra-Low Emissions Vehicle (ULEV II) emissions certification requirements.
For 2012, all Toyota Tundras have standard heavy-duty battery, heavy-duty starter, windshield wiper de-icer, daytime running lights (DRL), front and rear mudguards, and heated, power, outside mirrors. All Tundra grade models feature standard styled steel wheels for 2012. The Tundra DoubleCab and CrewMax models offer an optional Chrome Package that includes chromed exhaust top, side mirrors, door handles and chrome-clad 18-inch steel wheels. The 2012 Toyota Tundra is offered in two grades (Tundra and Limited), three cab styles (Regular, Double Cab and Crew Max), three wheelbase lengths (126.8, 145.7 and 164.6 inches, depending on model and configuration) and three bed lengths (78.7, 97.6 and for CrewMax only, 66.7-inches).
By combining popular equipment, Tundra’s option packages were simplified to make it easier for customers to find the right Toyota Tundra with the equipment they desire. Tundra grade Double Cab and CrewMax models now offer four streamlined packages: Convenience Package, Convenience Package with Bucket Seats, Upgrade Package and SR5 Package. Regular Cab offers four redesigned packages: SR5 Package, SR5 Upgrade Package, TRD Off-Road Package, and Color-Keyed Bumper Package.
The Toyota Tundra is equipped with standard 18-inch styled steel wheels with P255/70 R18 tires. Limited grade models get standard 18-inch five-spoke aluminum alloy wheels with wider P275/65 R18 tires and optional 20-inch five-spoke alloy wheels with P275/55 R20 tires. An optional TRD Off-Road Package combines off-road tuned suspension featuring Bilstein gas-charged mono-tube shock absorbers, P275/65 R18 BFGoodrich® off-road tires on 18-inch alloy wheels, plus fog lamps, fuel tank skid plates and TRD Off-Road graphics.
The available TRD Rock Warrior Special Edition package combines a tough off-road look with rugged off-road capability. Available only as a 4×4, the truck includes Bilstein® shock absorbers and 17-inch TRD Rock Warrior forged alloy wheels with LT285/70 R17 BFGoodrich All-Terrain T/A KO tires. The package is available in Black, Radiant Red, Magnetic Gray Metallic or Super White exterior colors with color-keyed front bumper and grille surround with matte black rear bumper. The Rock Warrior Tundra is also equipped with fog lamps, privacy glass and front bucket seats with eight-way adjustable driver’s seat, four-way adjustable front passenger seat and black fabric-trimmed seating surfaces. New for 2012, the package adds an auto-dimming rearview mirror with integrated backup camera display, compass, and HomeLink® universal transceiver.
The standard four-wheel disc brakes use large ventilated rotors – 13.9 inches and 1.26-inches thick – with four-piston calipers in front; and 13.6 x 0.71-inch with two-piston calipers in the rear. Anti-lock brakes (ABS) with Electronic Brake-force Distribution (EBD) and Brake Assist (BA) are standard on all Tundra models. EBD optimizes brake pressure at each wheel for greater control under braking, especially when cornering. BA is designed to determine if the driver is attempting emergency braking. If the driver has not pressed firmly enough on the brake pedal to engage ABS, the system supplements the applied braking power until pedal pressure is released.
The standard Automatic Limited-Slip Differential (Auto LSD) helps provide better acceleration in deep sand or mud and on mixed-friction surfaces. Compared to a conventional mechanical limited slip differential, the Auto-LSD system is much more responsive and has better wear characteristics. The Tundra’s VSC system integrates traction control (TRAC) and enhances traction on or off-road by helping keep the vehicle on its intended course. Integration of these technologies also provides driver-selectable versatility to tackle just about any road surface or driving condition. In “normal” mode, VSC, TRAC and Auto-LSD all function to help enable traction and control capability. “TRAC Off” and “Auto LSD” modes activate Auto-LSD to help extricate the Tundra from extreme conditions. The “VSC Off” mode turns off all three of these systems.
Toyota Tundra 4×4 models use a part-time, electronically controlled four-wheel drive system featuring a six-pinion planetary reduction gear set to provide 4×2, 4×4 Hi and 4×4 Lo ranges. The driver selects the drive mode using a dial on the dash.
