The colors and graphics spread through the Ram R/T-based interior, featuring black and Drone Yellow leather sport mesh seats with two-tone yellow/light-grey stitching. "Rumble Bee" lettering and Ram logos adorn chairs, floor mats and door bolsters. The interior center-piece is an actual amber-encased bee mounted into the 8-speed rotary shifter knob that lights up to expose a honeycomb pattern background. Two buttons below the knob control exhaust cutouts to bypass the Mopar cat-back dual-exhaust system, allowing the full sound force of a 5.7-liter HEMI V-8 to escape — loud and LOUDER! The unique honeycomb pattern is shared with door trim and the dash, where a milled aluminum "10th Anniversary" commemorative badge serves as the truck's ID.Under hood, the Ram 1500 Rumble Bee concept houses a 5.7-liter HEMI with 395 horsepower and 407 lb.-ft. of torque, mated to a TorqueFlite 8-speed automatic transmission. The HEMI is fitted with a custom gloss yellow and black engine cover with honeycomb graphic pattern. Mopar's cold-air intake system gives the HEMI a bump in performance and relentless torque is transferred through a 4.10 gear set for quick jumps off the line.
