First Look – 2013 Range Rover SUV

Land Rover has released the first photos of what it says is an all-new 2013 Range Rover. The fourth generation version drops its steel body for an all-aluminum monocoque design that is somewhat lighter. The upshot is total vehicle weight savings of about 700 pounds on what will remain about a 5,000 pound (or more) SUV in its two V8-powered U.S. versions. Currently the $80,000-$100,000 sport ute is rated by the EPA a 12 mpg city, 18 highway and 14 mpg combined, which is at the lower end of the class and requires a 28-gallon tank of premium fuel to provide a decent range.

More than 640,000 Ford Escape, Mazda Tribute SUVs Recalled for Unintended Acceleration after NHTSA Opens Defect Probe

Ford and Mazda are recalling Escape and Tribute SUVs from the 2001 up to the 2008 model year because a cruise control cable can stick and cause unintended acceleration. Since repair parts are not available, dealers will disconnect the cruise control as an interim measure for the safety defect.

The recall was forced when the National Highway Traffic Safety Administration two weeks ago opened an unintended acceleration investigation on 2001 through 2004 Ford Escape and Mazda Tribute SUVs after receiving 99 reports of unintended acceleration from owners. At least one fatality and nine injures are alleged in multiple accidents. Sixty-eight stuck throttle reports are from Ford Escape owners; thirty-one reports are from owners of Mazda Tributes.

GKN Purchase of Getrag Complete – $3.9 B Business Results

GKN has produced 250,000 drive systems for electric vehicles, but the current forecast for the EV business shows it growing much slower than early boosters such as President Obama hoped. Obama predicted there would be a million EVs on the roads by 2015, something that clearly is impossible. Sales of the Nissan Leaf and Chevrolet Volt totaled 10,000 ytd. The Fiat 500 EV produced in Mexico will be GKN’s first eDrive application in the Americas starting late this year. Total program volume is planned at 5,478 Fiat EVs. Continue reading

Honda Develops the First Traffic Jam Preventer?

Honda Motor Company today announced a computer program that prompts a driver to change behavior if it has the potential to cause traffic jams. Honda knows what traffic engineers know and commuters endure – the acceleration and deceleration behavior of one vehicle influences the traffic pattern of trailing vehicles and can trigger the traffic jams. (Nothing about road hogging SUV driver’s whose super-sized vehicles prevent trailing car drivers from judging and responding to traffic ahead since all the driver of the car behind can see is the SUV driver talking or texting on his cell phone until he jams on his brakes.)
