BMW M4 pitted against i8 in drag race

Germany's Auto Bild has set up a very intriguing drag race to settle not just an inter-brand rivalry within BMW but a question of the old school versus the latest tech. The BMW M4 is a leader among the traditional sports coupes with a turbocharged inline-six spinning the rear wheels, but the M has to tackle the cutting-edge i8 with its turbocharged three-cylinder augmented with electric drive. See what happens when they go head to head. Even on paper, the race looks quite close. The i8 weighs about 300 pounds less than the M4 and also slightly nudges it out on net torque at 420 pound-feet versus 406 lb-ft. Also in some shots, the pavement looks just a little bit damp here, which would benefit the i8's all-wheel drive setup. However, the M-car has a healthy horsepower advantage with 425 hp against the hybrid's 357 hp. The race commences after a short introduction. Watch and see whether the traditional tech or latest layout wins the day.

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 i8 Prototype

M Meets Edison
The real telling moment for the new BMW i division will be seeing how the recently tested 2014 i3 sells in its various markets, since that is the car that changes how we perceive our expectations of the brand. But this 2015 BMW i8 green supercar has all the earmarks of a slam-dunk project, we just needed to drive it and make sure for ourselves.
BMW has a spectacular test facility in southern France, called Miramas, and that's where we just had our first brief go behind the wheel of the i8. There were three cars for us there and they were dressed up in exactly the same paisley camo that we've all seen in the spy photos published everywhere for the past year. The interiors, though swathed in masking to hide all the details, varied in their color.
