Series 10 episode 8 is also a good one. Richard Hammond gets to drive a Renault R25, circa 2005. He had a hell of a time even getting the thing onto the track. The pit crew actually had to tow the car back to the garage to warm it back up; the tolerances on those motors are so tight that, when cold, they are effectively seized.
Around that period they had the central display at the Goodwood Festival of Speed. Clearly their engine management shop had been bored one day, because they'd written a test programme which enabled them to play tunes on the engine just by revving it, and were showing off for the assembled crowds. It's honestly that fast revving and high pitched that it could do a pretty decent job.
