2014 Audi A4 next car to go on big diet while adding features

The Audi A4 is expected to receive a major redesign over the next couple of years, and with the smaller A3 now gaining a sedan model, it is being reported that the A4 might be getting a little breathing room for a more advanced design and improved technology and features. According to AutoBild, this would include a drop of more than 200 pounds in curb weight, updated cabin tech and a wider variety of drivetrain options.
AutoBild states that Audi is looking to upgrade just about every detail - inside and out - when it comes to the 2014 Audi A4, and this includes a next-generation MMI system that uses two digital displays. Extensive use of magnesium, aluminum and plastics will help shave an estimated 220 pounds from the A4's curb weight, and in terms of engines, it sounds like the usual array of forced-induction, small-displacement gas and diesel engines will be on tap, but a bigger V6 TDI and a plug-in hybrid powertrain are also mentioned.

Audi, Toyota land on MIT's list of 50 Most Disruptive Companies

MIT Technology Review, a magazine all about innovation, has announced its list of the 50 most disruptive companies in 2013, and both Audi and Toyota made the cut. While the term "most disruptive" may carry a negative connotation in most uses (especially in the classroom), the acknowledgement in this case is an accolade, signifying that the company is at the forefront of its industry. In a nutshell, a disruptive company is a business whose innovations force other businesses to alter their strategic direction.
Audi made the list for "pushing autonomous cars closer to fruition with a laser-scanning road detector that fits in a vehicle's front grille," and Toyota for "expanding its dominance of the hybrid-car market with its new plug-in version of the Prius."

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.
