Volkswagen decides to keep Lamborghini and Ducati, transfers Bentley to Audi

Investors in the market for a high-end Italian manufacturer that peddles performance will need to keep looking. Volkswagen announced it will hang on to Lamborghini and Ducati in the foreseeable future. Executives in Wolfsburg, Germany, are making far-reaching changes to the Volkswagen Group to reboot it with a big focus on technology. Credible rumors claimed that the people in charge of the carmaker wanted to carve out Lamborghini — which owns Ducati — and ultimately list it, or at least a chunk of it, on the stock market in order to fast-track the group's electrification strategy. Going electric is expensive, so selling Lamborghini would have helped fund the expansion, and high-octane supercars don't easily go hand-in-hand with zero-emissions cars. "Volkswagen needs to change from a collection of valuable brands and fascinating combustion-engine products that thrill customers with superb engineering to a digital company that reliably operates millions of mobility devices worldwide," summed up Herbert Diess, the group's boss, during a September 2020 meeting. His team ultimately decided not to fully divest both brands. It's too early to tell whether part of Lamborghini will be listed on the stock market, as some insiders have suggested, or if those plans are off the table, too. Changes are coming to Bentley as well. While it's not being spun off either, it will fall under the Audi umbrella starting on March 1, 2021. Volkswagen explained linking the two companies will "allow for synergies to be achieved as part of the electrification strategy of the two premium brands," a statement which suggests they will share a growing number of components during the 2020s. Unverified rumors claim that Bentley will notably get its own version of an ultra-luxurious electric SUV code-named Landjet that Audi is currently developing. We've reached out to Bentley for more details, and we'll update this story if we learn more. Bugatti's future wasn't mentioned in the release; unconfirmed reports suggest it will be traded for a stake in Croatian start-up Rimac. Volkswagen's supervisory board also reaffirmed its support for Diess, who was appointed CEO in 2018 and who has played a significant role in the company's transformation. Finally, the board approved the development of what a statement refers to a future leading electric vehicle sold by the Volkswagen brand that will be developed and manufactured in Wolfsburg.

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 4.2-liter V8 to live again in next-gen R8

Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.
We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.
It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.
