Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

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.

Audi reveals facelifted A7 and S7 in Europe [w/videos]

Audi has revealed the nip/tuck and stylistic upgrades for the A7 that we got clues to in spy shots from back in January. The single-frame grille has been subtly reworked along with the lower front fascia and headlilghts. Those bulbs are underlined by a new design for the LED DRLs, and - in Europe - they can be had with Matrix Beam LEDs that come with dynamic turn signals. Out back is a tweaked bumper, as well as new exhaust tips and taillights with an LED pattern that mimics the front lights.
Cockpit inhabitants get new surface treatments like the aluminum and Beaufort walnut inlays, Valcona leather and five possible colors for the seats. The company's MMI Navigation Plus with MMI Touch is fitted with an Nvidia chip for faster graphics processing, and LTE-enabled internet connectivity is standard.
Up front, the 3.0-liter bi-turbo TDI gets a power boost to 320 horsepower and is attached to an eight-speed transmission; a seven-speed S tronic transmission is paired to the rest of the line. The revised 3.0-liter V6 TDI recently discussed at the Vienna Motor Symposium also joins the lineup, here offered in both the 272-hp and 218-hp variants, that latter "ultra" version said to return 50 US miles per gallon.
