The next presidential limousine might look like this

A few days ago, the United States Secret Service posted the bid requirements for a new presidential limousine, which is set to debut during the 2017 inauguration of our nation's 45th chief executive. It's hard to believe that the General Motors-built Cadillac dubbed "The Beast" is already due for replacement, but the fleet of presidential limousines is cycled every four or eight years, with bids accepted from any American automaker. We'll spoil the show for you: the odds of a company other than General Motors winning the bid is pretty slim.

Pagani Zonda Cinque Roadster (2009): first official pictures

By Ben Pulman First Official Pictures 03 July 2009 16:30 Pagani has unveiled a roadster version of its most radical road-legal Zonda ever, the Cinque. Just five Cinque Roadsters will be made, and with no roof, a 669bhp V12 engine, and a price tag broaching £1.1m (plus taxes) it's pretty special. Think again - and if Horacio Pagani wants to build 5 more gorgeous Cinques, this time without a roof so you can really hear that 7.3-litre V12 wail, then who are we to argue. There's a longer front spoiler, a flat undertray and diffuser, plus a new rear wing, all of which is enough to create the same 750kg of downforce at 186mph that Pagani claims for the coupe version.

'Gran Turismo' pays tribute to Senna with 'Ayrton's Wish'

We're finally starting to see the fruits of that labor -- a Senna-edition Playstation 3 bundle in Brazil notwithstanding. The first element of a month-long tribute from publisher Polyphony Digital is the above 20-minute film, "Ayrton's Wish." Two months before Imola, Ayrton told his sister Viviane that he wanted to give back to the country that so idolized him.
