With the price of oil skyrocketing, traffic gridlocking our cities and corn-powered cars exacerbating world hunger, what better way to respond than with a two-fingered, chassis-rattling, gravel-spraying, rubber-smoking salute to doom from the boys who've made test driving a lethal profession. Tonight, Jeremy Clarkson, James May and Richard Hammond take the new BMW M3, the Mercedes C63 AMG and the Audi RS4 to Spain. Jeremy concedes the Mercedes is not a pretty car. In fact, he says it's an axe murderer with headlights. But he absolutely adores it and he dismisses Richard's admonition that there's more to life than a big shouty engine. James, like Richard, can't understand why Jeremy would want a car that wants to kill him. James is smitten with the Audi's sonorous exhaust note, likening it to a tribute to Pavarotti. Meanwhile, Richard is impervious to his co-presenters' barbs about the BMW having more trinkets than a pensioner's mantlepiece. Richard: The BMW M3 is the world's best selling performance car. Jeremy: And is driven exclusively by cocks. So, to prevent further argument over the best German V8 super saloons, the three motorheads do what they do best: pit their favourite cars against each other in a drag race. Plus, Doctor Who star David Tennant swaps his time-travelling TARDIS for a Chevrolet Lacetti to become Top Gear's Star In A Reasonably Priced Car racing challenge. But can he beat his former co-star Billie Piper's time of one minute, 48 seconds? Tune in to see, and enjoy the madcap stunts while you can because the word from Britain is that James and Richard have not yet signed new Top Gear contracts with the BBC, despite their agreements expiring at the end of the month.
