Pagani Zonda R – the Ultimate Video

Great video of the Pagani Zonda R below Well, ‘Ultimate Video’ may be slightly overstating the case, but it is a crackingly good video. As we said when we reported that Pagani were taking a Zonda Cinque Roadster to the Geneva Motor Show - and again when we told you about the Zonda Tricolore – we are almost at the end of the Zonda, with the Pagani C9 due to bow on the world stage in September undisguised (although we’ve seen plenty of Pagani C9 spy photos). So the Zonda isn’t really news any more, and the Zonda R even less so.

GM to sell bifuel Chevrolet and GMC trucks

While gasoline hovers at about four bucks a gallon, natural gas is priced at the equivalent of $1.89 per gallon. Chevrolet and GMC are hoping to take advantage of that disparity by offering bi-fuel heavy-duty pickups for fleet and retail customers beginning on April 19, the day before Earth Day. The bi-fuel option will cost buyers $11,000, on top of the price of the pickups.

80mph limit plans 'to be revisited'

SHELVED PLANS to raise the motorway speed limit to 80mph will need to be revisited, a transport minister said as he declined to say whether he ever broke the current law to drive at that speed. Stephen Hammond said ministers were split on the move - which was unveiled with a fanfare by Philip Hammond in 2011 but then axed from the agenda by successors as transport secretary. Polling suggests a 10mph increase in the maximum allowed on the network would be extremely popular among motorists - and the transport minister recognised "a lot" already drove at the higher speed.
