The new-generation Tacoma moves well beyond the compact-truck dimensions of the previous model. Regular Cab 4x2 models are built on a new 109.4-inch wheelbase (an increase of 5.9 inches); PreRunner and 4x4 Regular Cab Tacomas sit on a 110-inch wheelbase; 4x2 Access Cab models ride on a 127.2-inch wheelbase (an increase of 5.3 inches); Access Cab PreRunner and 4x4 wheelbase is 127.8 inches. The Double Cab with the standard five-foot bed shares the 127.8-inch wheelbase, and the new Double Cab long-bed models ride on a 140.9-inch wheelbase. Front and rear track have been widened by nearly four inches, yielding more than four inches of additional shoulder and hip room. The Tacoma Access Cab models add dual rear access doors for 2005. Rear doors on Double Cab models are more than three inches longer than before and open to 80 degrees to give passengers easier access. New Engines & Transmissions
The 2005 Tacoma line features two engines: a new 2.7L VVT-i DOHC four-cylinder engine that produces 164 horsepower and 183 lb-ft. of torque and a revised 4.0L VVT-i DOHC V-6 that produces 245 horsepower and 282 lb-ft. of torque (replacing the 190-hp 3.4L V-6 in the 2004 models). Both feature a new Electronic Throttle Control System with intelligence (ETCS-i) that helps improve performance and fuel economy. Two new transmissions are offered with the V-6 engine, a six-speed manual and a five-speed automatic. The four-cylinder models offer a choice between a five-speed manual and a four-speed automatic transmission. New Composite Inner Bed
A significant change can be found in the factory-equipped composite inner bed, which features a new sheet-molded compound (SMC) deck and walls that are 10-percent lighter than steel, yet tougher and more durable. The bed deck features two-tier loading and integrated deck rail utility that includes four standard adjustable tie-down cleats. The rails are compatible with Toyota accessories, including cargo bed cross bars, a fork-mount bike rack, and diamond-plate storage boxes. An available 115V/400W powerpoint further extends the bed’s utility. Double Cab models offer a first-in-class roof rack system with crossbars that deploy from the roof rails. Interior storage has been maximized in Access Cab and Double Cab models by means of tumble-flat rear seats with underseat storage and, on Double Cab models, additional storage behind the rear seatback. On Double Cab and all models with bucket seats (except the sport seats), the front passenger seat folds flat and features a tray table. New Dynamic Control Features
In all 2005 Tacoma models, the standard four-wheel anti-lock brake system (ABS) is augmented by the electronic brake-force distribution (EBD) feature and brake assist. EBD optimizes brake pressure at each wheel for greater control under braking, especially when cornering. The brake assist system is designed to determine if the driver is attempting emergency braking. If the driver has not stepped firmly enough on the brake pedal to engage the ABS, the system supplements the applied braking power until pedal pressure is released. The optional vehicle skid control (VSC) and Traction Control (TRAC) systems give Tacoma models traction on- or off-road by helping the vehicle stay on course. The system detects front-wheel slide and rear-wheel slide during cornering and attempts to control either condition with throttle intervention and/or by braking individual wheels. The VSC and A-TRAC systems include Automatic Limited-slip Differential (A-LSD), which uses brake intervention in place of a mechanical-type LSD unit to help reduce tire slippage at the rear wheels. On automatic transmission models, the VSC and TRAC option also includes Hill-start Assist Control (HAC). When the option is ordered along with the TRD Off-Road Package on 4x4 V-6 automatic models, it also includes the Downhill Assist Control (DAC) system. By independently controlling the brakes at each of the wheels as needed, the HAC system helps to prevent the vehicle from rolling backward or slipping sideways during transition from a stopped position to climbing an upgrade. The DAC system uses engine braking to regulate downhill speed and independently control the brakes at each of the four wheels to improve directional stability. The feature also works in reverse and is automatically de-activated if the driver depresses the brake or accelerator pedals, presses the DAC button, or shifts into neutral.
