The Ariel Atom 3.5R is powered by a supercharged Honda Type R2.0 engine producing 350 Hp and 330 Nm of torque. The beast weights just 550 Kilograms (1,212). You've heard it, it's that light. This means it can reach 100 Km/H in 2.5 seconds thanks in part to the sequential paddle-shift gearbox.
You can watch it being driven by BTCC driver Anthony Ried around a test facility located near the Goodwood hill climb course in the video below.
