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.

Audi spearheads development of an ultra-luxurious EV code-named Landjet

The rumors claiming Audi wants to release a model positioned above the A8, and the reports of an ongoing electric car development program called Artemis internally, have seemingly converged. Citing sources inside the carmaker, a German media outlet reported the firm is busily creating a super-luxurious EV code-named Landjet. Audi is leading the development process, but sister companies Bentley and Porsche will reportedly receive their own version of the Landjet. All three models will likely take the form of three-row SUVs with generous dimensions. They'll be so big that none of Audi's production facilities will be able to manufacture them, according to an anonymous insider who spoke with German newspaper Handelsblatt. Luckily, Volkswagen makes vans, too. It's too early to tell what will power the Landjets. Audi assigned some of its most brilliant engineers to Project Artemis, and the technology they develop will permeate the three EVs before trickling down into cheaper models in the group. Expect high performance, a high driving range, and semi-automated driving technology. If the report is accurate, the Landjet vehicles will enter production in Hanover, Germany, by the end of 2024. The facility currently makes the Volkswagen Transporter, which is a direct descendant of the rear-engined Bus sold for decades, and it will start manufacturing the production version of the ID.Buzz concept in the coming years. Volkswagen hasn't commented on the report, and car companies rarely address speculation, but its Commercial Vehicles division released a statement in November 2020 that confirms the Hanover site will begin building SUVs about halfway through the 2020s. It's a major shift for a factory normally tasked with manufacturing vans. "Our main plant in Hanover is becoming the production site for three completely new premium electric vehicles in the Group. These D-SUVs are genuine flagship projects: premium, 100% electric, and highly automated," said Carsten Intra, the head of Volkswagen's Commercial Vehicles division, in a statement. He added the firm will invest about 680 million euros (about $807 million) to build a new assembly line, among other upgrades.

Audi, Google readying infotainment partnership announcement for CES?

The merging of our smart phones and automotive infotainment systems may be about to get an even bigger boost, if a report from Forbes is to be believed. The business publication is reporting that Google and Audi may announce a partnership at next week's Consumer Electronics Show in Las Vegas that would see Google's Android OS taking control of Audi's MMI infotainment system.
The move by Google would be a direct counter to Apple's iOS in the Car initiative, the marquee feature of which allows drivers to access the company's Siri digital assistant via a car's voice controls. According to Forbes, other iOS features that have found their way into cars include functions for iMessage, as well as audio and satellite navigation systems.
Audi and Google already enjoy a working relationship, with the tech company providing data services on many of the automaker's cars, as well as lending Google Maps to the MMI system. If this report turns out to be true, fans of Android could find Audis looking a lot more appealing.
