With these additions, the Tundra now offers a choice of 45 models in three wheelbases, three cab styles, three bed lengths, three engines, three trim levels and two-wheel or four-wheel drive.
Available engines include a 4.0-liter V-6 that produces 236 hp at 5,200 rpm and 266 lb.-ft. of peak torque at 4,000 rpm; a 4.7-liter i-Force V-8 that pumps out 276 hp at 5,400 rpm and 313 lb.-ft. of torque at 3,400 rpm; and a 5.7-liter i-Force V-8 producing 381 hp at 5,600 rpm and 401 lb.-ft. of torque at 3,600 rpm. The engines are equipped with the Acoustic Control Induction System (ACIS). Butterfly valves inside the intake manifold switch the length of the intake runners in two stages based on engine speed and throttle angle, improving efficiency across the entire speed range.
The 4.0-liter V6 and 4.7-liter i-Force V-8 are teamed with a five-speed automatic transmission that features uphill/downhill shift logic. The i-Force 5.7-liter is mated to a six-speed automatic transmission. An available tow package on all Tundra i-Force V-8 models increases towing capacity up to 10,800 lbs., depending on the model and drivetrain.
Wheelbases include 126.8 in. for regular cab/standard bed models; 145.7 in. for regular cab/long bed and CrewMax models; and 164.6 in. for the Double Cab/long bed models.
