2014 BMW 320i

When BMW switched its entry level 3 Series, the 328i, from a naturally aspirated, 3.0-liter six-cylinder to a turbocharged, 2.0-liter four-cylinder, we weren't entirely sure what to think. Sure, from a pure numbers perspective, the new 2.0-liter cooked the old 3.0's goose, delivering more torque at far more accessible engine speeds while boosting horsepower and fuel economy.
While we miss that revvy six-pot, the numbers for the 2.0 were just way too good to pass up. Then we received news of an even less-powerful 2.0-liter 3 Series - the 320i. This was interesting, as it saw BMW delving into a power level previously owned solely by the anemic Lexus IS 250 and its six-cylinder engine.
Could BMW make a sub-200-horsepower sedan that still drove the way we expected a 3 Series to drive? To find out, we borrowed the new 320i for a week of testing.

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 X6 stays the course with more power, RWD model

What would this world be without the BMW X6? Oh, sure, the whole coupe-crossover design trend surely would have started somewhere, but BMW was the first, launching its odd duck back in 2008. Much as we like to harp on the X6 (for being less functional and more expensive than the X5 on which it's based), people around the world sure do seem to like the thing, BMW having sold some 250,000 examples since the CUV's birth. And as you first saw thanks to leaked images this morning, the second-generation X6 has just arrived.
The shape is familiar, as are specific styling elements like the larger headlamps (now available with a full-LED treatment) and taillamps, mimicking those found on the X5. Two trims are available - xLine and M Sport - the former taking a more subdued approach, while the latter uses the traditionally bulgy and aggressive M-badged kit, with larger air intakes and matte aluminum grille bars. All X6s come standard with 19-inch wheels, and 20s are optional.
Regardless of trim, BMW will now offer the X6 in three guises here in the United States: sDrive35i, xDrive35i and xDrive50i. Dissecting the nomenclature, that means the first two models will be powered by BMW's 3.0-liter turbocharged inline-six, good for 300 horsepower and 300 pound-feet of torque. The sDrive X6 uses rear-wheel drive, while the xDrive, of course, uses all-wheel drive. Moving up, the xDrive50i uses the same twin-turbo 4.4-liter V8 as its predecessor, though power has been increased to 450 hp and 480 lb-ft. All X6 models are fitted with an eight-speed automatic transmission, and BMW says that the new powertrains are more efficient than before, though official fuel economy numbers have not yet been released.
