What is the name of the music/song from the car commercial?!

I think it's been featured in a number of commercials, I always think of some soft of sexy car driving through a tunnel at night!. Anyhow, there are no lyrics that I know of, I only know that it starts out with a smooth rock sort of guitar (a little bit of drums), then trumpets come in, "bah bah bah!" then guitar again!. If it helps, I know it was played on Top Gear series 3 episode 9, while James test drove the Jaguar!.

Help! I need to know; it's driving me nuts!Www@Enter-QA@Com
