With a shift knob that contains a bumblebee encased in amber, Ram’s new Rumble Bee concept truck seems to be gunning for Ford’s new performance pickup, the Tremor. The Rumble Bee can sting, with a 395-horsepower Hemi V-8. And it could suggest Ram is ready to revive the performance truck it offered as part of a limited run in 2003 – the original Rumble Bee itself paying tribute to the classic Dodge Super Bee muscle car Chrysler produced from 1968 to 1971.
