The last time Top Gear pitted an Ariel Atom against a motorcycle they used a CBR600RR, Jeremy Clarkson had his face rearranged and the car won. This time, it’s a faster car versus a faster bike. The Ariel Atom V8 makes 500bhp and has a power-to-weight ratio “in excess of 900bhp per tonne." The BMW S1000RR racing it in tonight’s episode makes 193bhp and weighs 183kg, giving it a power-to-weight ratio of 1,055bhp per tonne. Which is faster around the Top Gear Test Track?
Update: how'd the S1000RR's lap time compare to every other car Top Gear has ever tested, including the Bugatti Veyron?
Here's that original Ariel v CBR600RR segment.
According to MCN, the S1000RR was only 1 second slower than the Atom V8, making it the second fastest vehicle ever tested by Top Gear. It's 1:16.1 lap time means it beat cars like the Bugatti Veyron SuperSport, the Gumpert Apollo, the Koenigsegg CCX and even the Ferrari Enzo. Wikipedia has a full list of Top Gear's lap times.
Not bad for a bone stock superbike that, at $13,950, is many times cheaper than any car in the top 186 positions on the Top Gear Leader Board.
