The Carlos and Dieter Show promises more collaboration

Daimler and Renault-Nissan said Friday the automakers have expanded their four-year-old alliance to include putting a Renault diesel in the Mercedes C-Class, a Mercedes gasoline engine in an Infiniti and possibly will involve automated driving technologies in the near future. At a joint Paris Motor Show press conference dubbed 'The Carlos and Dieter Show' by European media, Renault-Nissan CEO Carlos Ghosn and Daimler CEO Dieter Zetsche said the alliance between the automakers is running strong and will expand into any area that makes financial sense for both companies.

Daimler and Renault-Nissan began their partnership in 2010 with plans to collaborate on three projects. They've since expanded that and are working on 12 projects together, including building a joint plant in Aguascalientes, Mexico. Renault-Nissan and Daimler are launching their first vehicles developed together from scratch: the Renault Twingo (which went on sale in September) and the new Smart Fortwo and Smart Forfour, which go on sale in November.

Recharge Wrap-up: Comparing Nissan Leaf performance by climate, natural gas iffy for trucks

A new Carnegie Mellon University study looks at the effects of regional climate variations on the Nissan Leaf. The study shows (unsurprisingly) that the ambient temperatures of different regions have effects on battery performance and the use of climate control, both of which affect range. Efficiency and grid mix determine regional differences in emissions per mile. CMU enumerated many of the differences in performance across the US. For instance, on the coldest day of the year, maximum range can be 70 miles on the Pacific Coast, while it is less than 45 miles in the Upper Midwest. These differences in efficiency can also affect adoption patterns. Read more at Green Car Congress. Battery charger manufacturer CTEK has licensed WiTricity wireless charging technology. CTEK looks to commercialize the wireless power transfer tech for use with electric vehicle batteries, making the "plug-in" aspect of EV charging unnecessary. WiTricity's charging technology stands out for its ability for distance charging via magnetic near field. "We are excited to be on the forefront of the next generation of battery charging products for consumers and industry, and look forward to leveraging WiTricity's ground-breaking technology to bring a new level of convenience and ease of use to market," says CTEK CEO Jon Lind. Wireless charging is convenient for the public, but also especially useful for emergency vehicles, which need to be ready at a moment's notice but also keep electrical systems online while the car is parked.

Switching heavy trucking fleets from diesel to natural gas could make economic sense, but the environmental benefits aren't as certain, according to a new study from UC Davis and Rice University. Certain regions - particularly California, the Great Lakes and mid-Atlantic regions - could benefit from the switch with minimal investment. "But to have an environmental advantage for reducing greenhouse gas emissions would take significant policy intervention," says Amy Myers Jaffe, executive director for Energy and Sustainability at UC Davis. This would mean stricter efficiency standards for natural gas trucks, as well as stronger regulations for methane leakage. Read more in the press release from UC Davis below.

Watch some vintage F1 cars blast up a Japanese mountain road

It's a rare treat to see classic Formula One cars racing anywhere, but watching them on a Japanese mountain road is absolutely sublime. The folks behind Motorhead from Japan took over the toll road's twisting stretch of tarmac to turn this impossible dream into a reality. The unusual opportunity of a closed mountain road would be a waste for only two vehicles, and there were plenty of drivers in amazing machines that wanted to blast up the hill. After the vintage F1 cars got their turn, some drifters in a Nissan GT-R and a Toyota GT86 added some tire smoke to the misty mountain air. A couple more GT-R racecars and some modern sports cars eventually joined them. Before the rain hit, this team had quite a party going on. This video features amazing camera work, but the music unfortunately drowns out the chance to hear these amazing racecars. If watching this leaves you wanting more, Motorhead released a video last year of another group of impressive performance vehicles on the mountain road.
