All-New 2014 Toyota Tundra

November 2013, Work Truck - Feature

by Mike Antich - Also by this author

The redesigned 2014 Toyota Tundra 1/2-ton full-size pickup truck features a new exterior design and new interior inspired by customer feedback requesting a more chiseled exterior and refined interior, with improved driver ergonomics and easy-to-use technology. 

The redesigned 2014 Tundra represents the first major change since the 2007 model-year. 

The 2014 Tundra offers three cab styles: two-door Regular Cab, four-door Double Cab, and the super-sized four-door CrewMax. Tundra Regular Cab and Double Cab models are offered in standard bed (78.7-inch) or long bed (97.6-inch) configurations, while the CrewMax comes with a 66.7-inch bed. All beds are 22.2-inches deep.

Tundra continues to offer three powertrains. A 4.0L dual overhead cam (DOHC) V-6 is standard on Tundra Regular and Double Cab models and produces 270 hp at 5,600 rpm and 278 lb.-ft. of peak torque at 4,400 rpm. It is paired with a 5-speed automatic transmission with uphill/downhill shift logic. Environmental Protection Agency (EPA)-estimated fuel economy is 16 mpg city/20 mpg highway/17 mpg combined.

The available 4.6L, DOHC i-Force V-8 offers 310 hp at 5,600 rpm and 327 lb.-ft. of peak torque at 3,400 rpm. EPA-estimated mpg fuel economy is 15 mpg city/19 mpg highway/16 mpg combined on 4x2 models and 14 city/18 highway/16 combined on 4x4 models.

The Tundra’s 5.7L, DOHC i-Force V-8 generates 381 hp at 5,600 rpm and 401 lb.-ft. of peak torque at 3,600 rpm. The 5.7L is offered in both gasoline and “flex fuel” variants. Fuel efficiency on 4x2 models is a competitive 13 mpg city/18 mpg/highway/16 mpg combined while the 4x4 achieves 13 mpg city/17 mpg highway/15 mpg combined.

Both V-8 models come standard with a 6-speed electronically controlled automatic transmission. 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.

Highlighting New Suspension Enhancements
Several enhancements have been implemented on the 2014 Tundra to improve performance. Shock-absorber valving has been retuned to improve ride quality over harsh surfaces.

Patented aerodynamic stabilizer fins have been added to the outside surface of the rear tail lamp lens, and the outside mirror bases. These patented “Aero-Fins” reduce the air turbulence along the sides of the vehicle and also aid in enhancing straight-line stability during normal driving conditions and while towing.

Interior cabin noise is reduced by the advanced design of engine compartment NVH treatments and innovative engineering. Among the many design developments are the installation of a new hood insulator design, a sound-absorbing dash, reduced windshield angles, a non-breathable headliner, door trim pads, and body mounts under the dash and rear panels help to reduce sound transmission from the engine compartment to the vehicle cabin.

Tundra’s advanced TripleTech frame uses wide, full-boxed rails for the front portion, a reinforced C-channel under the cab and an open C-channel underneath the bed to help maximize strength, ride quality and durability. The double A-arm front suspension uses coil-over spring shock units, while a front-mounted steering rack helps enhance steering feel and response. The rear suspension uses staggered shocks mounted outboard of the springs to improve the shocks’ dampening efficiency. Spring rates are tuned to provide a flat vehicle stance when fully loaded.
All Tundra models come standard with four-wheel disc brakes with ventilated rotors.

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 Vehicle Stability Control (VSC) system integrates traction control (TRAC) and enhances traction on or off-road by helping keep the vehicle on its intended course.

Tundra 4x4 models use an on-demand, electronically controlled four-wheel drive system featuring a six-pinion planetary reduction gear set to provide 4x2, 4x4 Hi, and 4x4 Lo ranges. The driver selects the drive mode using a dial on the dash.
