Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.

Audi builds its six-millionth Quattro-equipped car

All-wheel drive has become the norm particularly among German automakers. Mercedes offers its 4Matic system on a broad range of models, BMW counters with its xDrive system, Volkswagen has 4Motion, and the only Porsche you actually can't get with all-wheel traction is the Boxster/Cayman. But before all its competitors got on board with channeling power to all four wheels, Audi was making a name for itself with its Quattro all-wheel-drive system.
Now 34 years since the advent of the original Audi Quattro, the House of the Four Rings has built its six millionth vehicle equipped with all-wheel drive - only a year and a half since it hit the five-million mark. In fact these days nearly half of all new Audis are ordered in Quattro spec - more than any other automaker - resulting in a total of 710,095 Quattro-equipped Audis produced last year alone.
The landmark 6,000,000th vehicle was an SQ5 in monsoon gray metallic that rolled off the assembly line on Friday and is bound for a customer right here in the United States.
