Rolls-Royce Cullinan and BMW 8 Series spied south of Death Valley

Recently, we've stumbled upon a number of manufacturer prototypes running around. Usually, spy photographers sit and wait for hours with cameras primed in order to get a few shots of a car. We just got lucky. First, we caught the new Chevy Corvette ZR1 convertible during a Facebook Live video. A week or so later McGraw snapped a video of a ZR1 coupe cruising in his neck of the woods. Today, our ace photographer Drew Phillips caught a BMW test fleet filling up the new Rolls-Royce Cullinan and 8 Series coupe in Baker, Calif. Baker sits along Interstate 15, about halfway between Los Angeles and Las Vegas. It's just south of Death Valley, and, being late August, suggests that BMW was doing some hot weather testing. Drew was filling up his car when the fleet rolled in. There were at least two of the new king Rolls and a single 8 Series. Both cars were wearing a full swirl camouflage wrap. It's not an uncommon place to see prototypes. Still, seeing a whole fleet roll in is quite a sight. We've seen official photos of the Cullinan before, but these pictures give us our best view of the profile and rear we've had so far. From a distance, it looks like a high-riding version of the new Phantom with a hatch in place of the trunk. The taillights are obviously just filler units. Expect the final version to look very much like the squared off LED units on the Phantom. Likewise the interior and engine should be straight from the Phantom. That means a twin-turbocharged V12, though power is likely to be sent to all four wheels. We've seen the full BMW 8 Series concept a few times now. The proportions on the production car look the same, with a long hood and even longer wheelbase. The nose isn't quite as aggressive as the concept, but we expected the styling to be toned down to meet crash and safety standards. As for engines, look for six, eight and (hopefully) 12-cylinder power under the hood. A plug-in variant is also expected. Both cars have been in development for a long while, so look for full debuts sometime this auto show season. Maybe we'll happen upon some more test mules between now and then. Related Video:

BMW revisits its 8 Series

So why would BMW choose July 2 to release a retrospective on the 8 Series? Could it have something to do with the recent unveiling of the Pininfarina Gran Lusso Coupe concept, another sleek, B-pillarless V12 two-door, at this year's Villa d'Este? We have no idea, but the timing is likely coincidental.
This three-minute look at the 8 Series talks to Niels Hamann, who was smitten with the long-hooded coupe when it appeared in 1989 and finally bought one in 2004. Hamann also happens to be a project manager at BMW, and that came in handy when he wrote a book detailing every aspect of what was BMW's flagship for ten years but to the chagrin of many only managed one generation.
While we wait for the next clue about the Gran Lusso - 8 Series connection, check out the video below.

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.
