Audi S3 pitted against BMW M135i in track battle

Audi and BMW have long been enemies on both the road and the track, with their respective M and S/RS lines duking it out to the delight of auto enthusiasts everywhere. In this video from Evo, two of the rivalry's newest combatants take to the track - the Audi S3 and the BMW M135i.
The new Audi S3, which is finally coming to America, throws down with a 2.0-liter, turbocharged four-cylinder. 290 horsepower and 280 pound-feet of torque are deployed to a Quattro all-wheel-drive system via a six-speed, S-Tronic dual-clutch transmission, allowing the five-door Audi to scamper to 60 in under five seconds.
The BMW, which Americans will know as a long-roof version of the new M235i Coupe, comes to the track with 320 ponies and 331 lb-ft of torque. That's a good bit more than the Audi, but the M135i has only two wheels to send its power to, an eight-speed single-clutch automatic (a six-speed manual is available) and a slightly higher curb weight.

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 i5 could get Toyota-sourced hydrogen power

It's starting to feel like the automotive landscape is right on the cusp of a boom in hydrogen-fueled vehicles. After all, the Toyota FCV is nearly ready, Volkswagen is readying a fuel cell concept for this week's Los Angeles Auto Show and Hyundai already sells its Tucson Fuel Cell. The next big name to add to that list might be BMW, as the company's co-development deal with Toyota starts to bear fruit.
According to Autocar, BMW may use a version of the fuel cell system from the Toyota FCV in the future i5. As part of its eco-oriented i sub-brand, the i5 is expected to be a stretched version of the i3 (pictured above) with extra rear legroom and cargo space. It's unclear at the moment whether a battery-powered pure electric powertrain will also be available. If accurate, then the rumor could give the Bavarian brand a counterattack against Mercedes-Benz' planned fuel cell vehicle in 2017.
BMW and Toyota first signed the memorandum of understanding to co-develop fuel cells, lightweight technology and a sports car back in 2012, and they made the arrangement official in late 2013. So far, few details on the progress of the work have been disclosed, but the performance model has been rumored to use a front-engine, all-wheel drive layout with supercapacitors.
