Aston wants to build DBX on its new platform, not Mercedes'

Aston Martin is proceeding with plans to launch the DBX as its first production crossover. It just can't say at this point what it will be based on. Speaking with Automotive News Europe, Aston's new CEO Andy Palmer indicated that basing the DBX on a Mercedes SUV platform would not be its first choice because they "clearly sit in a very different space to the one we want to go" with the DBX. Instead, the company's first choice would be to build the crossover atop the new platform it's developing for its sports cars. "It just depends how high off the ground it could go," said Palmer. "I don't exclude the possibility of using some [Mercedes] parts, but I would say very much the primary route is our platform." The prospect of building an Aston SUV on Mercedes architecture – namely that of the GL-Class – has been on the table for some time now. The Lagonda SUV concept it showcased at the Geneva show in 2009 was based on the GL, and the two automakers have been forging a tightening alliance in the years since. The British automaker's next-generation engine is to be built by Mercedes-AMG, and it is expected to source other components from the German automaker as well. For its part, Mercedes has been taking a sportier approach with its latest crossovers, as demonstrated by the GLE Coupe that debuted before the more conventional version and the Concept GLC Coupe that previewed the GLK's replacement in Shanghai last month. Aston Martin, on the other hand, is building a new sports car platform that will underpin its next generation of luxury GTs, replacing the long-serving VH architecture that has served for decades as the basis for its entire model line. Perhaps the most surprising of ANE's report, though, is that Aston seems to be proceeding with plans to build the DBX apparently without even knowing what platform it will use.

Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
