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.

Here are all the new 2022 season F1 cars (UPDATED)

Update: Since this post's original publishing, the rest of this season's teams have revealed their 2022 cars. We've updated the post with all of them, so it now includes every 2022 F1 car on the grid. The updated story continues below. Reveals of the 2022 F1 cars are coming fast and heavy, and at this point, every team has shown off their redesigned cars. This being the case, we figured it was time to provide you all with a place to see all the cars at once. The gallery above holds photos of all the cars, and below you’ll see all them broken down by teams and drivers, along with quotes from the drivers and team leaders that come via F1Â’s official website where the cars were revealed. Mercedes W13 - Lewis Hamilton and George Russel "It just takes you back to being a kid," Hamilton said. "I think itÂ’s always exciting watching, I mean with this new era of car, weÂ’ve never seen such a drastic change, right? "So itÂ’s such a huge change in so many ways, that itÂ’s just been really interesting seeing the designers and everyone coming together to find the best ways of creating a masterpiece." “It feels incredible, obviously Lewis and I have driven so many laps in the simulator of this,” Russel said. “WeÂ’ve seen all the drawings, weÂ’ve had so many meetings and presentations about it, but suddenly seeing it all come together, seeing all of the men and women who have put so much hard work and grit into making this, and coming together here, I think it looks incredible. “And I think the silver [coming] back, weÂ’ve had an incredible livery with the black in the past couple of years – but the silver back on track I think is going to look incredible." Ferrari F1-75 - Charles Leclerc and Carlos Sainz “I think it looks aggressive, it looks radical, and I think it looks beautiful also Â… I just hope itÂ’s fast,” said Sainz. “ItÂ’s innovative, different, thinking a bit out of the box. I like it because itÂ’s just radical, which is what you want to see when you see a new car.” “Yes, I do [like the livery],” Leclerc said. “I think it fits perfectly. ItÂ’s a bit of a dark red, looks a bit more aggressive, but for a car like this, I think it fits perfectly.

Daimler, Geely mull China as production hub for hybrid powertrains

FRANKFURT — Daimler and Geely on Friday said China could emerge as a manufacturing and export hub for hybrid powertrains jointly developed for Volvo and Mercedes-Benz cars. Earlier this week, Daimler said it would cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. The engines will be produced in China as well as in Europe, and Geely and Daimler will cooperate in engineering, sourcing and production, the companies said in a joint press release. "The export of the engine from China is considered to be an option," the release further said. Mercedes-Benz aims for more than half of its passenger car sales to be comprised of plug-in hybrids or purely electric vehicles by 2030. Geely is ChinaÂ’s most internationally known automaker. It owns Volvo Cars and Lotus, almost half of Proton and 9.7% of Daimler. Through wholly owned company Polestar, it builds low-volume Polestar 1 hybrid performance cars in the western city of Chengdu and Polestar 2 volume sedans in Taizhou in the east. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. An Conghui, President of Geely Holding Group, President and CEO of Geely Auto Group said: “This project reflects the need for economies of scale and targeted research and development investment in clean and highly efficient powertrains and hybrid drive systems and their applications." Geely also plans to build a plant with annual manufacturing capacity of 30,000 premium EVs in the western city of Chongqing, run by a wholly owned, newly registered company, according to documents on its website. Geely and Polestar declined to comment. The plan comes as foreign automakers including BMW AG and Tesla expand EV production in the worldÂ’s biggest market, sourcing major EV components such as batteries locally and often even exporting a portion of the vehicles it builds.   Auto News Earnings/Financials Green Plants/Manufacturing Mercedes-Benz Volvo Green Automakers Future Vehicles Hybrid
