Petrolicious reconnects with the BMW M coupe

With the look of a clown shoe on wheels, the BMW M Coupe was a product of using what was around to create something great. Starting with the Z3 convertible, BMW's engineering team added a bulbous roof to improve rigidity, and for the M version, it dropped in the inline six from the contemporary M3. While the result wasn't a beauty queen, the car more than made up for any aesthetic complaints in driving pleasure. Petrolicious talks to owner Alex McCulloch about just what makes the tiny three-door so special in its latest video. With a fairly short wheelbase, plenty of power, and a rear suspension from the E30-chassis BMW 3 Series, the M Coupe can be a quite handful at the limit. "I used to say it wanted to kill me, but now we've reached an agreement where it's not quite as murderous," McCulloch says. He's eventually found that the only real way to exploit the coupe to its fullest is on the track, where he competes in time trials. To get lap times as low as possible, the BMW now wears quite a few mods, but McCulloch says that it's all reversible. Figure out what competitive hang gliding has to do with driving in this clip from Petrolicious. Related Video:

Mini nixes plans for 7-seater, Countryman to stay largest model

Contrary to popular belief, it seems that Mini's growth plans do have a limit both in size and number of models. During the 2014 Geneva Motor Show, it unveiled the six-door Clubman concept (pictured above) that was 4.4-inches longer and about two-inches wider than even the current Countryman crossover. Mini design chief Anders Warming says that this is the new size limit for its models, and the BMW subsidiary isn't building a larger, seven-passenger vehicle above the current Countryman.
"We won't build anything bigger than the Countryman, not at this moment. You should be able to park a Mini in a city, so a Countryman or this new Clubman is as big as it should be," said Warming to Auto Express in Geneva. Rumors going back to last November, pegged the Mini as developing an even larger vehicle to take on mainstream CUVs.
While Warming is ruling out a bigger Minis for now, a smaller one like the Rocketman concept still might be in the cards. He said that the project has been warmly received but still had to be investigated because "it's a numbers game." So if bigger Minis aren't coming, there still might be a slim chance for a smaller one.

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.
