Toyota doesn't have a press conference scheduled for the 2009 Chicago Auto Show, but it does have two noteworthy debuts. The first is an all-new 4.6L V8 engine that will replace the current 4.7L V8. The new eight-cylinder produces 310 hp and 327 lb-ft of torque while delivering an estimated 15 mpg city / 20 mpg highway. That puts the new 4.6L V8 near the head of the pack in terms of power and fuel economy for standard V8s in the segment. The engine will also be paired with a "new" six-speed automatic. Rather than simply use the six-speed auto that's paired with the larger 5.7L V8, Toyota engineers instead used the truck's five-speed auto, added an extra gear and respaced the ratios.
Toyota's second debut in Chicago was a new Platinum Package available on Tundra CrewMax Limited models with the 5.7L V8. Though it shares an adjective with the new Ford F-150 Platinum, Toyota's top shelf truck is more low key and the package adds $5,140 to the vehicle price. Included is a new grille with chrome bumpers, unique 20-inch wheels, daytime running lamps, branded door sill protectors and Platinum badging around the truck. The package also includes a number of upgrades for the interior like a power moonroof, nav system and wood trim on the shifter, steering wheel and door trim.
