VW recalling 2.64M vehicles worldwide over engine, light issues

Volkswagen is staging a massive, worldwide recall that's already grown from 1.68 million to 2.64 million vehicles and covers three different issues across a number of vehicles. We already reported on 61,000 Tiguans getting recalled over lighting issues - that was just in the US. Globally, however, VW will be recalling 800,000 Tiguans, according to Automotive News, with the focus on CUVs built between 2008 and 2011. The issue with the Tiguan relates to a simple fuse swap, so this is rather unremarkable, aside from the sheer number of vehicles being fixed. The real, troubling issues relate to gearboxes and pickups.
239,000 Amarok pickups (pictured right) are being recalled over fuel leaks, while 1.6 million vehicles are being recalled to swap the synthetic oil in dual-clutch transmissions with mineral oil. Now, the transmission issue is one for the global Volkswagen Group to address, not just the VW brand - vehicles from Audi, Škoda and Seat use the same seven-speed DSG and are covered under the recall, as well.
Why the switch from synthetic to mineral oil? Apparently, using the synthetic oil in a DSG and then subjecting it to stop-and-go conditions or heavy loads in a hot and humid climate can lead to electronic malfunctions, according to a Volkswagen press release. The switch, from the sounds of it, is largely a preventative measure.

Audi R8 Spyder looks like heaven at the Green Hell

After Audi took the wraps off the new R8 coupe at the 2015 Geneva Motor Show, we knew it would only be a matter of time before the convertible version arrived. Now, we've spotted the droptop during testing on and around the venerable Nurburgring Nordschleife in Germany. The new Audi R8 Spyder is expected to closely mirror the fixed-roof supercar we've already seen. Only instead of a tin top, of course, it'll have a folding fabric roof mechanism. This goes against the recent retractable hardtop trend, and the featured is used by the Ferrari 488 Spider and McLaren 650S Spider. Some revised air vents appear to be part of the R8's convertible package, as well. Otherwise, we can anticipate the same specs as the R8 coupe. The latest model ditched the previous version's V8 engine in favor of 10-cylinder options: a 5.2-liter V10 with either 533 horsepower in "base" spec or 602 hp in the V10 Plus model. Both drive all four wheels through a seven-speed dual-cluch transmission. The jury's still out on whether Ingolstadt will slot a smaller engine option into the R8, particularly for markets where tax brackets are determined by engine displacement. But whatever the coupe gets, the convertible is likely to offer it as well. Related Video:

Audi to lap Hockenheim in driverless RS7

An automaker like Audi will always have a number of different research and development projects going at the same time, and some of them might take on very different approaches. At one end, you'll have its racing programs, and at what you'd assume would be the other, self-driving prototypes. But Ingolstadt is preparing to bridge that gap by running an autonomous prototype at racing speed around the famed Hockenheimring.
Set to take place on Sunday, October 19, during the DTM season finale at Hockenheim, the driverless RS7 will motor at speeds up to 150 miles per hour, right up "to its physical limits with millimeter precision."
Audi anticipates that "the world's sportiest piloted driving car" will run a lap time of just over two minutes, at which the RS7 would stand not only to be the fastest driverless car ever to lap the circuit, but also potentially the fastest four-door - if it can beat the 2:02.71 lap time set by a BMW M3 sedan in 2007.
