2014 BMW 4 Series

Because Four Is Greater Than Three
Say what you will about the name 4 Series, there is a method to BMW's madness. On one hand, it's easy enough to just buy into the logic that odd numbers are reserved for sedans and wagons, and that even numbers are reserved for coupes and convertibles. On the other hand, consider the idea that the higher numbers are used to separate the more dynamic, more engaging vehicles that use the same platform. It's that sort of separation that differentiates the 6 Series so nicely from its 5 Series roots, after all. And if we're being cynical, it also allows BMW to charge a bit more money for its lower-volume offerings.
So with the new two-door version of the 3 Series, BMW has gone the route of strengthening the dynamic virtues of its F30 chassis to create a car that's more removed from its sedan kin than one might think. And after spending some time with the new 4 Series on the roads around Lisbon, Portugal, as well as the famous Circuito do Estoril racetrack, it's increasingly clear that calling this car a 3 Series Coupe simply wouldn't be fair.

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.

BMW solar roof helps i3 drivers even when sun isn't shining

At the Consumer Electronics Show, BMW has announced a release window for its i Wallbox Pro that unites domestic solar power and the electricity grid. The box itself was shown off during last year's i8 drives and it rests inside a solar carport to control the simultaneous delivery of both solar power and the electric grid energy to recharge an i8. One drive attendee wrote how the Wallbox Pro display showed that it was providing 3.4 total kW to the coupe, with 2.8 kW from the sun and 0.6 kW from the grid. At CES, BMW said the i Wallbox Pro, brought to life by BMW DesignWorks, will be available in 2016. For homes that aren't equipped with solar power, or when solar isn't available, the system will draw power from the grid when it's least expensive. The Munich manufacturer also announced a concept storage solution using discarded batteries from its electric cars, where excess energy from solar or other sources could be held for later use for a vehicle or the home itself. BMW will be demonstrating the i Wallbox Pro at CES and the press release below has more information. BMW i Home Charging Services unveiled at the CES Consumer Electronics Show in Las Vegas Pioneering integrated charging solution for electric vehicles brings further reduction in charging costs and integrates home solar generating systems with the household electricity system. Munich / Las Vegas- January 5, 2015... At the Consumer Electronics Show CES 2015 in Las Vegas (6 – 9 January 2015) BMW i will unveil a further innovative product from its 360° ELECTRIC portfolio: BMW i Home Charging Services. This smart solution for home charging of electric and plug-in hybrid BMW models is based on the smart home-enabled BMW i Wallbox Pro system already presented by BMW in spring 2014. How the smart charging service works. Using BMW i Home Charging Services, the vehicle is charged with homegenerated solar power whenever this is available. At other times, or if the household does not have a solar generating system, the vehicle is automatically charged at the cheapest off-peak rates. This makes it possible to take advantage of flexible electricity pricing that varies depending on the time of day. In the USA, this can result in savings of up to 800 dollars a year. With this fully automated charging service, customers get a simple-to-operate system that integrates vehicle charging with the household electrical system and online-based data systems.
