GM's Lutz to retire May 1

General Motors Vice Chairman Bob Lutz plans to retire from the automaker effective May 1, according to a statement released by GM on Wednesday. Lutz, 78, had been serving as a senior adviser to GM Chairman and CEO Ed Whitacre after shelving retirement plans to take charge of the automaker's marketing after it emerged from bankruptcy in July 2009. An outspoken executive who both challenged global warming and championed GM's all-electric Volt, Lutz is credited with revitalizing GM's product development efforts after being hired by former GM CEO Rick Wagoner in 2001.

Pagani Zonda Revolucion is the last ever Zonda. Apparently.

The Pagani Zonda Revolucion – the ultimate Zonda We’ve lost count of the number of ‘Special Edition’ Zondas Pagani has churned out over the years, but it’s probably close to the point where a non-special Zonda is rarer than the special editions. Now we get treated to one last special edition Zonda with the Pagani Zonda Evolucion, an evolution of the track-only Zonda R promising even more extremes of performance and price. The Evolucion’s 6.0 litre V12 engine produces a massive 789bhp which, thanks to a weight of only 1070kg, promises to be unbelievably quick with a power to weight ration of 749bhp per ton – better than the Veyron.
