BMW i3 gets official worldwide

Even though we recently drove a near-production version of the BMW i3, the car still wore light exterior and interior camouflage. Today, BMW took off that little bit of camo and made a big announcement: The i3 will go on sale in the US for $41,350 in the second quarter of 2014. That does not include any state or federal incentives that could lower the price or the $925 destination fee. The i3 will debut with three trim levels, which BMW is referring to as Worlds: Mega (standard in the US), Giga and Tera.
The BMW i3 is chock-full of new technology afforded by its design as an EV from the start of development, which has resulted in a vehicle layout unique to the i3. BMW has named it LifeDrive architecture, and it features the Life Module and the Drive Module. The Life Module is the i3's pillar-less passenger cell, which is the first mass-produced monocoque made of carbon fiber reinforced plastic (CFRP). The tougher-than-steel material is also 30-percent lighter than aluminum, which contributes to the i3's relatively light weight of 2,700 pounds (preliminary US figure) and, in turn, increases its energy efficiency. Expect more of this technology to find its way into future BMWs.
The Drive Module, a 100-percent aluminum chassis mounted under the Life Module, houses everything that makes the i3 go. It includes the 22-kilowatt, 450-pound lithium ion battery mounted as centrally as possible, and provides power to a rear-mounted electric motor that turns the rear wheels. With 170 horsepower and 184 pound-feet of torque from zero rpm, the single-gear i3 can accelerate from 0-30 miles per hour in 3.5 seconds and 0-60 mph in about 7.0 seconds, but it has a top speed of only 93 mph. BMW says the i3 has a real-world EV range of 80-100 miles, and the standard charger can fill the battery in three hours. Opt for the SAE DC Combo Fast Charger and 30 minutes is all it takes for a full charge; 20 minutes will bump the battery to 80 percent. For customers who have range anxiety, BMW gives them the option to install a 34-hp, 650cc two-cylinder generator as a range extender for the electric drive system.

Renderings may show upcoming BMW 4 Series Gran Coupe

We've already shown you spy images of the latest member of the BMW Gran Coupe family, the 4 Series Gran Coupe. Following the trend of the larger 6 Series Gran Coupe, the 4 Series variant grafts a spare set of doors onto its two-door body.
Now, the f30post forum has come up with what it says are patent drawings of the new 4GC (originally from Chinese site Autohome.com), giving a glimpse of what the coupe-sedan-thingy looks like without its camo in the way. What we're seeing is seemingly a mix of the 3 Series GT (noticeable around the rear window) with the larger Gran Coupe styling, while retaining the current 4 Series front end.
We can't say it looks great, but as these are merely renderings, it's far too early for us to come to a final conclusion on the overall look of the 4 Series Gran Coupe. Have a look up top at the patent images. We've also included our spy photos of the new Gran Coupe below. Let us know what you think of the latest niche product from BMW down in Comments.

Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)
