Jeremy Clarkson tests the new BMW M3 at the track before switching to another BMW, the space-age, hybrid powered i8, for a revealing trip up the A1 to Whitby. When he gets there, and fuelled by a portion of fish and chips, Clarkson must decide which of the two he would rather take for the drive home.
Also in this programme, Richard Hammond marks the imminent demise of the legendary Land Rover Defender with a heart stopping attempt to drive one straight up the side of a dam.
