2015 BMW M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.

New BMW i3-like Visio.M EV concept uses lightweight resin

It's not a new version of the BMW i3, but an updated version of a lightweight concept car from SABIC, BMW, the Technical University of Munich, Daimler and others does bear a certain resemblance to the well-designed plug-in city car. From the black "glass" in the hatch to the angled line tail lights to the up-and-down window line, you can see a sort of family resemblance (see an i3 comparison photo here). And, of course, they both have an electric powertrain. But the changes made to the new lightweight urban electric concept vehicle is more of an exercise in what's possible rather than a way to evolve the i3 and i8 into a broader i family of vehicles. Even so, what we see here is interesting, since SABIC found all sorts of new ways to take weight out of the car as part of the Visio.M (Visionary Mobility) project, which was first announced in 2012. Let's start with the window material, which as you might guess from the quotation marks above, is not made of glass but is instead SABIC's Lexan polycarbonate (PC) resin plastic. The lower weight (the PC helps shed about 29 pounds) adds two miles of range while the PC resin has better thermal conductivity compared to glass and so does even more because the HVAC system can be more efficient. According to SABIC's computational fluid dynamics analysis, an extra 9-10 miles of range, in fact. Without the battery, this concept weighs just 992 pounds. Remember, BMW already made a lot of weight-reduction measures in the i3 thanks to carbon fiber reinforced plastic, so to make the "glass" lighter would only help boost efficiencies on a production vehicle that uses a resin like this. Read more below. SABIC's LEXAN™ resin delivers weight savings and thermal efficiency for new ultra-lightweight electric car concept developed by BMW-led Visio.M Consortium Munich, October 20, 2014 Today, at the Technical University of Munich (TUM), BMW, Daimler, TUM scientists and a consortium of industry participants showcased a lightweight urban electric concept vehicle with various advances, including an all-plastic design of the car's windows. The windows are made of LEXAN resin, a polycarbonate (PC) material, and coating technologies from SABIC, a leading developer of PC glazing for automotive windows and many other thermoplastic solutions for the automotive industry.

2015 BMW X4 xDrive28i

When BMW unveiled the X6 back in 2008, critical reviews were mixed, to say the least. By all accounts, the heavyweight crossover actually drove quite well, but the idea of a BMW X5 that traded a lot of functionality for polarizing looks and a higher price tag seemed like a tough sell. Then it went on sale and quickly proved to be a cash cow. Today, the German brand has moved over a quarter million of the things worldwide. Unsurprisingly, this success has moved BMW to double down on its so-called Sport Activity Coupe by adding a smaller variant. The all-new X4, while not a bad steer in and of itself, makes even less sense than its big brother, particularly when viewed alongside BMW's other offerings. Like the X6 and X5, the X4 borrows heavily from another of the brand's utility vehicles, in this case, the less-costly X3. Also like the X6, this new crossover-coupe's styling is sure to cause a schism among critics and consumers alike. You can probably guess where the majority of the Autoblog camp falls. To be totally frank, the exterior of the X4 is simply ghastly to this writer, particularly in this tester's eye-catching paint. Admittedly – and much like the X6 – there's not much objectionable from the A-pillar forward, where the X4 has a lot in common with the X3. It's only once moving towards the rear that things well and truly go wrong. There's just so much visual mass, and it's been made worse by the way BMW designers wussed out. Bear with me. Compare the profile of the X6 with the X4, and pay particular attention to the roofline on the bigger vehicle. The angle of the roofline is noticeably more dramatic on the X6, which comes at the expense of second-row headroom (an oft-criticized area for the big boy). For the X4, designers tried to have their cake and eat it too, maintaining second-row headroom but with a coupe-like profile. The result is an X4 that is bulbous and uncouth from the B-pillar back, more hunchbacked Gran Turismo than svelte Gran Coupe. BMW might have been better served if its exterior work had followed the stylings of the cabin, which is more or less a clone of what's on offer in the X3. Material quality is still great, with soft-touch plastics and available cool-to-the-touch brushed aluminum throughout. I really dug the Ivory White Nevada leather and contrast red stitching on this test vehicle, as it provided an eye-pleasing departure from the sea of blacks, grays and tans so typical of the luxury crossover market.
