Porsche offers design walkthrough of Panamera Sport Turismo

The Porsche Panamera Sport Turismo was arguably the best concept car of 2012, and Porsche has been building upon that momentum by teasing us with videos of its first-ever station wagon design. After showing us some driving shots of the Sport Turismo, Porsche released a more in-depth and behind-the-scenes look at what it took to take the Panamera shooting brake from a full-scale clay model to the final product we saw on stage at the Paris Motor Show. In the video, Michael Mauer, Porsche style director, and Mitja Borkert, general manager advanced design style, both give a little insight about what went into creating the Sport Turismo Concept.
More than just a station wagon version of the Panamera, the Sport Turismo has a totally distinctive look nose to tail. Some of the key elements the designers touch on in the video include the Porsche-signature raised front fenders, the wide rear shoulders, the front wing inspired by the 918 Spyder, and even some of the car's unique touches, including the headlights and the three-dimensional "Porsche" lettering across the liftgate made from glass. One of the more exciting aspects of the concept - which is sadly just glossed over in the video - is the rear liftgate spoiler that features "variable aerodynamics" that sounds like it acts similar to the retractable spoiler on the current Panamera.
We still don't know if the Panamera Sport Turismo will make it into production, but if you want to see what went into creating this exciting concept car and see the different build phases designers went through to create the Paris show car, check out the video by scrolling below.

Porsche 918 Spyder recalled over bad wiring harness

An investigation of customer concerns has led to a global recall of the Porsche 918 Spyder, including 223 units in North America. The carmaker said that a carbon fiber component can damage a radiator fan wiring harness, so it is contacting owners directly to have their cars brought in for a service inspection. The issue affects cars built through the end of April 2015; cars built after that use a revised design. Dealers will remount the wiring harness, a process that should take half a day. You'll find more information in the press release below. Related Video: Porsche recalling 918 Spyder models for service inspection Precautionary recall: affected customers will be contacted directly Atlanta. Porsche has issued a global recall for 918 Spyder models that have already been delivered. This precautionary recall for a service inspection affects 223 vehicles in the United States. This is because the electric wiring harness for a radiator fan in vehicles manufactured up until the end of April 2015 could be damaged by a carbon-fiber component. The wiring harness will be examined and optimally remounted in the work shop. The cause was identified following a detailed examination of inquiries. Corrective measures have subsequently been taken in manufacturing. The owners of the affected vehicles will be contacted directly by Porsche Cars North America. The service visit, which will be free of charge, will be arranged as quickly as possible and the inspection will likely require the vehicle to be left in the shop for half a day.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
