This dinosaur continues to evolve. The Campagna Motors T-Rex 16S (www.campagnamotors.com) is the latest high-performance three-wheeler from the Montreal company, which has been building versions of the T-Rex since 1995. The 16S has a starting price of $62,000. Driver and passenger sit side by side just inches above the pavement in the open cockpit. They can stow their cargo in the removable plastic pods on each side of the engine. The 16S weighs only 1,100 pounds and is powered by BMW’s potent 1.6-liter, water-cooled inline-6 motorcycle engine, which develops 160 hp and 129 ft lbs of torque.
