Next-gen Audi Q7 shows off its wares ahead of Detroit

Audi has put the Q7 on a massive diet, trimming over 700 pounds. Meet what is sure to be one of the bigger debuts at the upcoming 2015 Detroit Auto Show. The next-generation Audi Q7 has been the subject of spy shots and conjecture for quite some time. After all, it was easily the oldest vehicle in the Audi range, having hit the market way back in 2006. But with this new model, Audi has comprehensively updated its fullsizer, adding some cutting-edge tech, updating some classic engines, and taking a whole lot out. As is the theme nowadays, particularly among large crossovers and SUVs, Audi has put the Q7 on a massive diet with a mix of ultra-high-strength, hot-shaped steel and aluminum, trimming over 700 pounds of body fat and lowering the Q7's weight to just under 4,400 pounds. This was accomplished while maintaining virtually identical dimensions to the current model. While Audi USA hasn't released its info on the Q7, the Euro-spec model will continue to offer a pair of engines that should be very familiar to US consumers, with a 3.0-liter, supercharged V6 gas engine and a 3.0-liter TDI V6. The European engines, though, have had their CO2 emissions halved, while actually increasing performance (we should expect similar from the US engines). The 3.0-liter TDI has been bumped up from 240 horsepower to 272 ponies, while torque is up from 406 pound-feet to 443. The 3.0-liter TDI has been bumped up from 240 horsepower to 272 ponies, while torque is up from 406 pound-feet to 443. This extra grunt has trimmed the 0-60 time from a leisurely 7.3 seconds down to 6.3, while the fuel economy has jumped up to 41.3 US miles per gallon, converted from the European cycle (so expect the EPA numbers to be a bit lower). The supercharged 3.0-liter, meanwhile, has been amped up to match the output of its application in the S4 sport sedan, jumping from 280 hp and 295 lb-ft to 333 ponies and 325 lb-ft. Once again, the 0-60 time falls dramatically thanks to the power bump and weight loss, dropping from 7.7 seconds to a far more zippy 6.1. The most exciting news is the long-rumored arrival of the Q7 E-Tron, a plug-in hybrid that's mated to a six-cylinder diesel engine and Quattro all-wheel drive. Audi claims this world-first production powertrain will return 138.4 US miles per gallon, emit less than 50 grams of CO2 per kilometer and allow the Q7 E-Tron to travel up to 35 miles on electric power alone.

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 Q7 to be first diesel plug-in from VW group

Lending credence to prior reports, the next Audi Q7 will be available with a diesel-powered, plug-in-hybrid powertrain, Automotive News claims, after speaking to a source in the Volkswagen Group. Both the gas and diesel-powered Q7 will debut in 2015, with the diesel PHV to arrive after that. Unlike Europe's other plug-in diesel, the Volvo V60, Audi's Q7 will be sold on both sides of the Atlantic, the source told AN. You can see a few spy photos of the Q7 PHV above. Audi research and development boss Ulrich Hackenberg previously confirmed that diesel plug-ins would be arriving earlier this year, although it wasn't clear which models the ultra-efficient powertrains would be offered on, or which of those would be offered here in the US. Time to play the waiting game...
