Watch the incredibly complicated operation of Porsche's new targa roof

Despite Porsche having claimed the name, targa tops are nothing new. In addition to the semi-roofless version of the 911, plenty of cars in the past have used removable roof panels - the new Corvette Stingray has one (as have prior generations), and this type of open-air experience has been available on past vehicles like the Pontiac Solstice Coupe and Honda Civic del Sol.
But when Porsche took the top off its brand new 911 Targa here at the Detroit Auto Show, it was indeed cause for pause. Simply put, this is one of the most complicated and intricate electronic roof panel removal techniques we've ever seen, save perhaps, for the setup found on the Japanese-market Civic del Sol from the 1990s.
We won't spoil the video for you, but basically, rather than just the roof panel coming off, the entire rear glass area lifts away the body in order for the small section over the passenger compartment to slide back. This has to be incredibly expensive to repair once it inevitably breaks. And we highly doubt you'll be able to operate this mechanism at any speed.

Porsche suspends 911 GT3 deliveries amidst fears of spontaneous combustion

Seeing pictures of Italian supercars burst into flames by the side of the road, as our compatriots at Axis of Oversteer point out, has become something of a usual sight. But a Porsche? Surely those meticulous German engineers have got that taken care of, right?
Not necessarily. Reports coming in from Europe indicate that no fewer than five 911 GT3 coupes have "spontaneously combusted" in the past few weeks, prompting Porsche to launch an investigation. In the meantime, they've reportedly ceased deliveries of the new GT3 while they try to determine what the problem is and work to rectify it.
We wouldn't be surprised to see a recall issued once the problem is resolved, but for now, we'd encourage existing owners to be extra vigilant behind the wheel - or better yet, leave their cars in the garage for the time being. You wouldn't want to drive a 475-horsepower rear-drive sports car through a Polar Vortex, anyway, right?

Porsche kicks off Macan production at revamped Leipzig plant

After over two years of construction and roughly 500 million euros ($684 million at current rates) invested, Porsche finally opened its Leipzig, Germany, factory expansion on February 11. The improvements to the plant are dedicated to building the Macan and include a new body shop, paint shop and assembly line that are advancing Porsche's goal to sell 50,000 Macan's per year. The company believes that the new model is going to push it to over 200,000 annual sales 3 years ahead of schedule, and the enlarged branch can support even more Macan production, if there is demand.
"We are totally convinced in the qualities of this location and that the Macan will be a marketing success," said Porsche Chairman Matthias Müller during the opening celebration. The company opened its Leipzig factory in 2002 to build the Cayenne and added Panamera production in 2009.
The Macan models are due to launch in the US this summer with prices starting at $49,900. Scroll down to learn all of the details about the Macan's Leipzig assembly plant.
