it’s a good thing that the BBC still has Ken Block Top DO cool car stuff but it’s a bad idea to let him loose like that in the streets of London! The fact that Matt LeBlanc was the host he picked up makes it that much better. Ken Block is the king of killing tires and The Hoonicorn is the perfect tool for the job! This Video was filmed back when the Hoonicorn was still only N/A now it has a huge set of twin turbos coming out of the hood! WHAT DOES THE RED BUTTON DO!
