AutoWeek office swag: Mazda rotary-engine keychain with realistic motion

When I got the keys to our long-term 2011 Mazda 5 last week, they came with a surprise--this aluminum-and-brass keychain in the shape of a rotary-engine housing, complete with moving rotor. The rotor doesn't just rattle around or spin in a circle. Thanks to a thumbwheel on the back of the housing, coupled with a timing gear and offset crank journal, the thing actually moves in an approximation of epitrochoidal motion just like a real Wankel.

Mercedes fixes diesel injector problems

Mercedes say that a new injector system for C Class and E Class diesels with the OM651 engine have now been fixed. So extensive was the problem that many owners were waiting months for their cars to be fixed as Mercedes struggled with a mounting pile of broken cars and injectors that were failing. Mercedes tell us that the problem was fixed with the release of new injectors later in 2010, but Cars UK readers have continued to complain about their cars needing multiple visits to dealers with injectors failing multiple times (that original story garnered more than 500 comments from disgruntled Mercedes owners).

Land Rover OKs LRX-based small SUV for Range Rover

Land Rover will put its striking LRX concept car, first displayed at the 2008 Detroit auto show, into production with the help of a $37.1 million grant from the British government. But in a move suggesting it will be pitched further upmarket than originally intended--against four-wheel-drive rivals such as the Audi Q5, the BMW X5 and the Mercedes-Benz GLK--the LRX will reach showrooms wearing Range Rover badges. "Internal studies have shown that if we deliver the LRX to market, it would be best suited to the Range Rover brand," Land Rover boss Phil Popham said.
