Replacing the Tundra's 4.7-liter i-Force V-8 for model year 2010 is a new V-8 that rings in with a tad less displacement but more power, torque, and efficiency. Based upon the mighty 5.7-liter V-8, still the truck's top engine, the new unit displaces 4.6 liters, 310 hp, and 327 lb-ft torque. Toyota says the new engine will boast the best fuel economy of any full-size V-8 truck V-8 when it goes on sale next month.

Replacing the Tundra's 4.7-liter i-Force V-8 for model year 2010 is a new V-8 that rings in with a tad less displacement but more power, torque, and efficiency. Based upon the mighty 5.7-liter V-8, still the truck's top engine, the new unit displaces 4.6 liters, 310 hp, and 327 lb-ft torque. Toyota says the new engine will boast the best fuel economy of any full-size V-8 truck V-8 when it goes on sale next month.
The 4.6-liter shares cylinder bore diameter with the 5.7 but features a shorter stroke to reduce displacement and therefore consumption. While official EPA ratings have not yet been calculated, Toyota estimates mpg ratings of 15/20, far better than the outgoing i-Force's best-case of 14/17 in two-wheel drive models. The same six-speed automatic found with the 5.7 yields best possible performance and efficiency.
In addition to the new V-8 engine, Toyota will offer two new Tundra trim packages for 2010. The Tundra Platinum Package will be available only in CrewMax Limited models with the 5.7-liter V-8 and the Flex Fuel option; for $5,140 it boasts full-on luxury treatment with Platinum badging, door sill protectors, daytime running lamps, 20-inch wheels, and a billet-style grille with chrome bumpers.
Those wishing to dress their truck down can opt for the Tundra work package, aimed at selling trucks to those who actually use the bed out back on a regular basis. The Work Truck Package keeps it simple with idiot lights in place of most gauges, basic black bumpers, a plain vinyl bench seat, and a single dome light for the cabin. This back-to-basics Tundra features prices anywhere from $550 to $655 less than other Tundras, and can still tow up to 10,800 lbs. with the optional 5.7-liter V-8.
