Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.

Recharge Wrap-up: Atieva making EV with former Tesla talent, Holland lowers PHEV incentives

A reduction of tax incentives on company cars in Holland is expected to put the brakes on plug-in hybrid sales. Cars are taxed at an average of 25 percent, with plug-in hybrids taxed at just seven or 14 percent, depending on emissions. Taxes on PHEV company cars will increase to 14 and 21 percent. With company car leases making up a third of vehicle sales in 2014, the uptake on PHEVs "will likely go back to regular volumes," according to Volvo's Christiaan Krouwel. It could be a boon for battery electric cars, as their tax rate will remain at four percent for company cars. Read more at Automotive News Europe. Ford is testing cylinder deactivation in its 1.0-liter EcoBoost engine. On-road prototype testing has shown improvements in fuel economy of as much as six percent. Ford engineers developed a system using a new dual mass flywheel, pendulum absorber, and tuned clutch disc to allow cylinder deactivation under a wider range of speed and engine loads with less NVH. "The highest priority in the development of new combustion engines for automotive applications is the ongoing reduction of fuel consumption," says Ford's Andreas Schamel, presenting Ford's findings to the Vienna Motor Symposium.

The Silicon Valley-based startup was founded in 2007 by a former Tesla vice president, and its roster includes 12 other former Tesla employees. Already well funded, Atieva is now looking to fill its ranks with more talent, with 32 engineering positions, two recruiter positions and other job openings posted at its website. As for the EV it is working on, Atieva says it is "redefining what a car can be, by building an iconic new vehicle from the ground up." Read more at Charged EVs. Testing shows that Joule ethanol, made from recycled CO2, meets standards for use in the US and Europe. In partnership with Audi, Joule has been working toward making its recycled CO2 fuels ready for commercialization. "We are pleased to achieve another critical step towards our planned near-term delivery of fuel-grade ethanol from recycled CO2," says Joule President and CEO Serge Tchuruk. "Using waste CO2 as a feedstock, our technology has the two-fold advantage of reducing greenhouse gas emissions and producing cost-competitive, drop-in fuels." Joule will use these test results to get government approval for the use of its ethanol in highway fuel.
