German carmakers recall 630,000 diesel vehicles in Europe

Mercedes, Opel, Porsche, and Volkswagen will recall over 630,000 cars in Europe, according to reports Friday. No diesel car has been able to get under the legal emissions limit in real-world driving, according to a German government investigation. While only Volkswagen Group has been using a specific "defeat device", other carmakers have been playing with their exhaust gas recirculation (EGR) systems. Depending of the manufacturer, the systems have been cut off at a certain temperature. In a specific test cycle the systems operate to fulfill the legal requirements, but in everyday use the limits are exceeded. According to the magazine Der Spiegel, the supplier Bosch is behind this programming and has provided it to all German automakers. The mentioned carmakers have announced recalls, but many other manufacturers are also mentioned by name in the report, including Alfa Romeo, Chevrolet, Dacia, Fiat, Ford, Hyundai, Jaguar, Jeep, Land Rover, Nissan, Renault, and Suzuki. PSA Group, which produces Peugeot, Citroen, and DS cars, declared yesterday that its offices were raided following an emissions investigation.

Revel in the glory of the Porsche 911 engine factory

A flat-six engine pumping away behind the driver defines the Porsche brand for many people, whether they are buying a Boxster, Cayman or 911. If you want to appreciate the sound and fury concentrated in the rear of these German sports cars even more, then take a tour of the company's 911 engine factory in Zuffenhausen, Germany, to see the work that goes into each one. We're long past the days of automotive assembly lines being deafening, dirty affairs, but it's still somewhat shocking to see just how sterile the plant in Zuffenhausen is. Each person wears a matching gray jumpsuit and gloves, and there's not a drop of grease of them. While the components are constantly coming down the line, there doesn't appear to be much of a rush. It's just a slow, steady movement that gives workers time to complete their appointed tasks. At least in this video, the employees don't even seem to talk to each other; the only sound is the hum of the plant or whir of tools. It's transfixing to watch these famous engine slowly come together largely from human hands. News Source: Cars via YouTube Plants/Manufacturing Porsche Technology Performance Videos engine

Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:
