Famous UK TV show Top Gear tested the Ariel Atom V8, which is powered by two inline-four motorcycle engines. The supercharged 3,0-liter V8 delivers 500hp while weighing only 1200 pounds. The means the Atom has 900 horsepower per tonne, a ratio that shames everything from the Lotus to the Lexus LF-A. The BMW S1000 RR features a 999cc inline-four that produces 193 hp, 83 lb-ft or torque and can rev up to 14,200. The bike has a power-to-weight ratio of 1,055 horsepower per tonne.
