Gibbs Sports Amphibians launches the Quadski

Gibbs Sports Amphibians has unveiled the Quadski, an amphibious all-terrain vehicle that, according to company founder Alan Gibbs, obliterates the distinction between land and water transportation. The 1,300-pound, 10.5-foot-long Quadski looks a bit like a jet-powered personal watercraft sitting on top of a single-seat ATV, but it's what's underneath the vehicle's molded composite body that separates the high-speed Quadski from larger, slower amphibious predecessors. The Quadski draws power from a BMW K 1300 Motorrad motorcycle engine capable of producing 175 hp.

New Porsche Panamera GTS takes to the track (video)

New Porsche Panamera GTS takes to the track The new Porsche Panamera GTS is the latest Panamera variant to arrive – the ninth Panamera, no less – and is, as all Porsche GTS models are, a harder-edged take on the more mainstream variants. With its naturally aspirated 4.8 litre V8 producing 425bhp, and pushing those horses through a PDK ‘box to all four wheels, the Panamera can scoot to 62mph in a very respectable 4.5 seconds on its way to a top speed of 179mph. Not bad for a big saloon car that eschews forced induction and can carry proper-sized passengers in comfort.

rusEFI: Open-source homebuilt fuel-injection set to rival Megasquirt

Most of us would never go back to the dark ages—say, before 1990—when you could still buy new vehicles with carburetors and clunky distributors. From the point of view of those of us who like to modify our cars, however, the black-box nature of engine-control computers limits our options for making changes to how our fuel-delivery and ignition systems function.
