2015 BMW M3 and M4 configurator launched, no lunch hour safe

BMW has just made your lunch break a little more interesting by launching the configurators for the M3 and M4. Pricing and options for the new sports coupe and sedan was revealed just a few days ago, but it's always more fun to see the visual effect your personalizations have on the bottom line.
The M3 and M4 start at $62,000 and $64,200, respectively, without a $925 destination charge. However, as soon as the configurator is opened, both models default with metallic paint ($550) and the M Double-clutch Transmission ($2900), plus extended leather on the M3 ($950) and full leather on the M4 ($3,500). This is basically the way they were shown when displayed at auto shows. Of course, there's nothing preventing users from setting up these performance machines however they like.
So sit down at your desk with a cup of coffee or a sandwich and create your perfect German sport sedan or coupe. It's always fun to see how much money can be spent on a dream car.

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.)

BMW M4 spied in coupe and convertible form

From the sound of it, we'll have to wait until the Detroit Auto Show to see the production version of the BMW M4, but spy shots show the new hi-po BMW testing recently in both coupe and convertible form. Showing a lot more skin than recent spy shots, these M4 prototypes look very similar to the M4 Concept we saw at Pebble Beach.
Carryovers from the concept car include the funky mirrors, bulging hood and the slotted front fascia vents, but the rear fascia seems to be missing the added flair of the concept and, as expected, the carbon fiber front splitter and exhaust tips are also missing from these M4s. Like the current M3 Convertible, the drop-top version of the M4 will utilize a retractable hard top.
