BMW planning smaller Z2 roadster

It's been a few years since we heard about the BMW Z2, a compact, two-seat convertible that would slot in below the aging Z4 (shown above). Now, though, the crew at Car and Driver are back with details on the oft-rumored roadster.
The big shock for enthusiasts on this one is C/D's report that the Z2 will spin its front wheels, rather than its rears. A front-drive roadster is strange enough, but a front-drive BMW roadster? It's apparently true, though, as the new model would share its platform with the front-drive Mini and 2 Series Active Tourer rather than with the racier 228i or M235i coupes.
According to C/D, the rumored Z2 could be powered by a range of three- and four-cylinder, turbocharged engines, although it's more likely to be a four-only affair. Power should range from 160 to 230 ponies, while an M variant could arrive with 300 horsepower (that's a whole lot of power for front-wheel drive...).

134K BMW 5 Series recalled for taillight issue

BMW is voluntarily recalling 134,100 cars due to a faulty ground terminal in the taillight bulb carriers, causing the sudden failure of brake lights, turn signals and reverse lights. The recall covers 2008 through 2010 5 Series models produced between March 1, 2007 and December 31, 2009, and includes everything from the 528i to the mighty, V10-powered M5. It's unclear if this recall is limited to sedans or extends to the 5-Series Touring.
There have been no reported cases of injuries, fatalities or crashes associated with the taillight issue. BMW will be issuing recall notices to affected owners in the coming weeks, asking them to report to dealers so that the bulb carriers on the taillights can be replaced. All repairs are, naturally, free of charge. Scroll down for the official recall notice from the National Highway Traffic Safety Administration.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.
