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.

Daimler and Volvo could jointly develop internal combustion engines

BERLIN — Luxury German carmaker Daimler and Volvo, owned by China's Geely, are considering cooperating to cut the costs of developing combustion engines, a magazine reported on Sunday, citing unnamed company sources. The Automobilwoche weekly cited a Volvo manager as saying there were initial talks with Daimler, but no concrete plans, while a company spokesman said it was too early to talk about firm projects, although it was not excluding anybody. A Daimler spokesman said the company's cooperation with Geely, which owns a 10% stake in the German carmaker, was developing in a positive way, but declined to comment further. Global tariffs, accelerated by a trade war between China and the United States, as well as higher investment requirements for electric and autonomous vehicles, are forcing carmakers to seek new ways to cut and share costs. In October, Volvo said it would merge its engine development and manufacturing assets with those of Geely, creating a division to supply in-house brands and also potentially others with next-generation combustion and hybrid engines. Automobilwoche said this new division would start operating by the end of March, which could be a possible starting point for cooperation with Daimler, while a further step could be a partnership to develop electric power trains. Geely and Daimler have said they plan to build the next generation of Smart electric cars in China through a joint venture and the two companies are also cooperating on a premium ride-hailing service in China. Geely bought Volvo Cars in 2010 from Ford, allowing the Swedish brand to operate on an arms-length basis. But in recent years, it has deepened cooperation between the two brands. Volvo already supplies engines to some Geely-branded vehicles, sharing technology through Geely's Lynk brand. Both companies share and develop common vehicle platforms.

Weekly Recap: Mercedes continues the pseudo-coupe craze with AMG-tuned CUV

But as BMW's X6 has demonstrated, sport sells in in the crossover segment, and Mercedes is giving the people what they want. BMW proved there is a market for crossover utility vehicles designed to look like coupes – as much as a vehicle with four doors and noticeable ground clearance can look like a coupe, anyway. Now comes the reply from Mercedes-Benz: the GLE Coupe. The rakish crossover is a harbinger of things to come from Mercedes, as it begins the company's transition to a new nomenclature and marks the debut of the AMG Sport line. It also continues the recent coupe craze. Designers from many automakers, like Nissan and Volkswagen, have increasingly turned to swoopy, dramatic styling to make utility vehicles and sedans seem more desirable. By revealing the GLE 450 AMG Sport model first, Mercedes is clearly hoping to cast the GLE Coupe as a sportier, lifestyle-oriented alternative in its lineup of beefy crossovers and SUVs. Mercedes used the word "sport," or a variation of it, 53 times in its press release, so uh yeah, it's sporty. It's not an empty promise: Benz means business with the AMG Sport line. This GLE Coupe gets a 3.0-liter biturbo V6 rated at 362 horsepower and 384 pound-feet of torque paired with Mercedes' new nine-speed automatic transmission, and it runs with 4Matic all-wheel drive. Specs on the other GLE Coupe models were not disclosed. But as BMW's X6 has demonstrated, sport sells in in the crossover segment, and Mercedes is giving the people what they want. After all, more than 260,000 people have bought X6s since 2008, and Mercedes wants a piece of that. From certain angles, the GLE Coupe even looks vaguely like an X6. "This is really a vehicle that is all about status," said Dave Sullivan, product analysis manager for research firm AutoPacific. "You can buy a SUV that doesn't have the inherent qualities of a SUV, such as cargo hauling. People will likely be drawn to the looks. Coupes are all the rage." BMW, however, isn't running from the fight, and the updated 2015 X6 is arriving in showrooms this month. It also added a smaller sibling, the X4, to its coupe-crossover stable in July. The GLE Coupe arrives next year, though Mercedes hasn't specified exactly when it will hit showrooms from the factory in Alabama, or specified details on the rest of the non-AMG Sport models. In 2008, it was surprising the X6 was a hit. In 2015, it will be even more surprising if the GLE Coupe isn't.
