Audi and Porsche squabble over future product platforms

In the buildup to the 2014 24 Hours of Le Mans, Audi delivered an amusing video that worked on the playful rivalry between the German brand and its favorite frenemy, Porsche. We called it sibling rivalry, and at the time, it may have been just that. But just like sibling rivalries, it's all fun and games until someone gets hurt, and that's just what seems to be about to happen in the formerly peaceful Volkswagen Group family.
A new report from Automobile calls out the growing animosity between Porsche, who is backed up by Bentley, and Audi, whose primary ally is Lamborghini. No blows have actually been thrown, although there is a fair amount of "he said, she said" going on.
As Porsche tells it, for example, the new global fullsize SUV architecture being developed by Audi isn't up to snuff, citing size and structure issues, as well as an inability to accommodate a wide variety of engines.

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:

Techart Porsche 911 Targa 4S is a tuner's attempt at being tasteful

We've not been terribly nice to the aftermarket tuners of the 2015 Geneva Motor Show. That's largely because they don't deserve our kindness. Techart, though, is not going to be the subject of derision, largely because aside from painting this Porsche 911 Targa a particularly lurid shade of yellow (and finding seat upholstery and trim to match), the changes aren't particularly offensive. Hell, paint it black, silver or red, and it'd just look like a more aggressive Porsche. That's largely because it is. Techart has behaved itself, fitting a brand new body kit featuring a new rear spoiler, diffuser, front splitter and side skirts, and replacing the much of the interior componentry with carbon fiber and aluminum components. The tuner doesn't mention the exact name of the shade used both inside and out on this Targa, although those with more conservative tastes will rest easy knowing that "stylistic harmony with standard or Techart individual paint is guaranteed." Techart's deft aesthetic treatment hides a similarly light tweaking under the sheetmetal. This car features a new exhaust system, complete with four staggered exhaust pipes that have been finished in black chrome. And that's it. There aren't 17 turbos or a new intake manifold crafted from free-range ivory. It's the same 400-horsepower flat six found in a normal Targa 4S. Techart has fitted its own springs, although it doesn't tell us how much (or even if) the ride has been lowered. 21-inch alloys round out the more practical changes. Check out our full gallery of live images of Techart's latest creation, direct from Geneva.
