Wheelies: The $2 Billion Addition Edition Nissan recently announced it would build a $2 billion factory in Aguascalientes, Mexico, to support production of compact cars in North America. Scheduled to open in late 2013, the plant would have capacity to build 175,000 cars a year and would supplement Nissan's two other plants in the country. Earlier this year, the automaker was rumored to be jointly building a plant in Mexico with Daimler, its strategic partner, but Daimler was not mentioned in Nissan's media materials and has not publicly commented on Nissan's announcement. Nissan Manal al-Sharif, the Saudi woman who was jailed last May after defying Saudi Arabia's ban on female drivers, was reported killed in an automobile accident Wednesday by Agence France-Presse. The Guardian, however, was contacted by Ms. Sharif after the report was widely distributed by other media outlets. She said the identity of the crash victim would remain anonymous at the request of the woman's family. Representatives from Congress visited the Washington auto show during press previews Thursday, during which praise for Detroit's automakers was liberally sprinkled. Representative Ed Markey, Democrat of Massachusetts, said he was confident that domestic automakers would meet and exceed corporate average fuel economy standards for the 2017-25 model years. "I'm very optimistic," he said. BMW released details this week about its first M Performance vehicles, conceived to fit between the high-performance cars of the M division and their standard equivalents. Dave Buchko, a BMW of North America spokesman, said the vehicles announced this week would not be sold in the United States. Each features a 3-liter in-line 6-cylinder diesel engine generating 381 horsepower and 546 pound-feet of torque, with assistance from three turbochargers. The engine appears in a 5 Series sedan and wagon, as well as the X5 and X6 crossovers. Special M badging distinguishes the cars from the standard models, but the bodies bear few other outward signifiers of the M division.
