Bmw: M3 on 2040-cars

AWD BMW M5 is headed our way

Remember the rumor about the BMW M5 going all-wheel drive? Well, there's definitely some truth there because these spy shots show BMW testing the Autobahn-storming sedan with the ability to spin the front and rear wheels. Our spy shooters grew suspicious when they saw this seemingly normal-looking M5 appearing to turn all four wheels during ice testing. They checked it out and snapped these shots underneath clearly showing power routed to the front axle. While this shows that the tech is at least being tested on a current-gen M5, all-wheel drive is probably not coming until the next 5 Series model, which is already being evaluated. The idea of power going to the front and rear axles for this sport sedan might polarize some hardcore brand fans as a break with tradition. However, the head of the M division thinks the change is a priority to actually put torque down effectively. The future vehicle is slated to get at least 600 horsepower and pack it into a lighter platform. Rear-drive M5 purists can take heart, though. The all-wheel-drive system would reportedly be an option, and it would be rear-biased to still let drivers hang the tail out, if the desire arises.

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.

First Ride: 2015 BMW M3 and M4

Getting Our Butts In The Seats
Both the non-M BMW 3 Series sedan and 4 Series coupe have so far brought much pleasure to us at Autoblog. The terrific four-cylinder 328i trim has become our favorite of the 3 Series line, while we have yet to get a chance at the 428i coupe. That said, the 35i trim powered by a 3.0-liter TwinPower Turbo inline six-cylinder engine is not exactly to be sniffed at.
We all know the ones you're really waiting for, though. The F80 fifth-generation M3 sedan and the supremely sexy F82 M4 coupe. Rumors have been buzzing for a couple of years now that the engine would be another V8, only turbocharged this time, or else a tri-turbo six. Well, today BMW confirmed that the mill under the hood's power bulge is a 3.0-liter inline six-cylinder TwinPower Turbo of the biturbo variety, referred to internally as "S55B30 variant."
