In this video AutoExpress pits two Mugen tuned cars through their paces at the race track. On one side we have the Ariel Atom Mugen which features a 2.0 liter engine boosted up to 270 hp, and on the other, the new Honda CR-Z Mugen which will soon make its official debut at Goodwood Festival of Speed. Granted, you can’t really compare these two, but this video gives a good chance to see the CR-Z Mugen in details. Although it’s a one-off car for the time being, it’ll soon spawn a production version.
