From Toyota press: The second-generation Toyota Sequoia full-size sport utility vehicle enters its third model year with a new standard 4.6-liter V8 that is more powerful and more efficient than the 4.7-liter V8 it replaces. In addition, all 2010 Sequoia models add driver and front passenger knee airbags, a Cold Kit with heated side mirrors and windshield wiper de-icer, and daytime running lights to their safety roster, along with numerous new amenities and user-technology features. Many more popular optional features are now standard equipment on all models, making Sequoia nearly mono spec, adding considerable extra customer value and simplified vehicle ordering for 2010.
The Sequoia is available in SR5, Limited and Platinum grades. In select areas, the Sequoia features as standard E85 Flex Fuel capability on 4x4 5.7-liter V8 models.
Sequoia is available with a choice of two V8 engines, a new 4.6-liter and the 5.7-liter unit it debuted with. Both engines run on recommended regular-grade fuel. The standard engine for the 2010 Sequoia SR5 is the new 310 horsepower 4.6-liter i-Force V8, which replaces the previous 276-hp 4.7-liter V8. The new 32-valve DOHC engine features aluminum alloy cylinder heads with Dual Variable Valve Timing with intelligence (VVT-i), which controls valve timing and overlap on both the intake and exhaust camshafts to optimize power, fuel efficiency and emissions. Peak torque is also up, now 327 lb.-ft. at 3,400 rpm vs. 314 lb.-ft. at 3,400 rpm for the 4.7-liter engine.
The new 4.6-liter V8 is teamed to a six-speed electronically controlled automatic transmission, compared to a five-speed automatic with the previous 4.7, benefitting both performance and fuel economy. Highway fuel economy estimates improved, now with and EPA rating of 19 mpg (2WD) vs. 17 mpg with the previous 4.7-liter V8.
As before, the Sequoia Limited and Platinum grades feature a standard iForce DOHC 5.7-liter V8 engine teamed to a six-speed electronically controlled automatic transmission, and this powertrain is optional for the SR5. The 5.7-liter iForce provides outstanding acceleration performance and enables the Sequoia to tow up to 10,000 lbs. (depending on model grade and equipment), putting it among the leaders in its class.
The 5.7-liter engine produces 381 hp at 5,600 RPM and 401 lb.-ft. of torque at 3,600 RPM, among the highest outputs in this vehicle class. Critical to customers who tow, the 5.7-liter V8 produces 90 percent of its peak torque at just 2,200 RPM. A Tow/Haul mode modifies shift points for optimal performance. The Sequoia's towing hitch is integrated into the frame as a single unit.
The 5.7-liter V8 is also equipped with Dual Variable Valve Timing with intelligence (VVT-i). An Acoustic Control Induction System (ACIS) switches the length of the intake tract in two stages, based on RPM and throttle angle, to optimize torque across the engine speed range.
In the six-speed automatic transmission for all models, Toyota's flexible torque converter lock-up control enhances efficiency, with lock-up occurring in fourth, fifth and sixth gears. The Multi Mode four wheel drive system available for all grades uses a two-speed transfer case with a lockable TORSEN® limited-slip center differential to power the front and rear wheels. The transfer case is shifted electronically via a rotary knob, and it locks with the push of a button.
