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.

2015 Audi A3 E-Tron [w/video]

Over the years, we've had a chance to test a lot of Audi E-Tron vehicles, from very early all-electric prototypes (back then we only got to sit in the passenger seat) to the A6 L E-Tron PHEV and the A1 E-Tron plug-in hybrid. All of them were concepts and promises, merely whispers of what was possible, even as the Nissan Leaf, Chevrolet Volt and two Tesla models were making waves in the marketplace.
As we learned last year in our Deep Dive of the E-Tron project, all of the concepts, prototypes and rumors have finally come to fruition in this A3 Sportback E-Tron. Previously, we were given a chance to drive a prototype, but it was only very briefly. Last week, we finally got to run a production-representative example through the hilly roads between Vienna, Austria and Munich, Germany. After spending a solid day with Audi's first marketable E-Tron vehicle, we can say that it's a most amazing bit of engineering, in particular for the way that Audi has done so much to hide the fact that this is an electrified vehicle. Not entirely, of course, but the idea was to make the A3 Sportback E-Tron a no-compromise PHEV. And that means it drives and feels, in many ways, like the standard A3 Sportback despite over 700 extra pounds. Oh, and there's a charge port hidden behind the four rings in the grille.

Audi reveals R8 E-Tron Piloted Driving concept at CES Asia

Designed as they are to take the driver out of the equation, you might think that the idea of an autonomous vehicle would seem diametrically opposed to that of a supercar. But Audi disagrees. The German automaker has cooked up a series of "piloted driving" concepts that are increasingly focused on performance, and this could be the ultimate iteration yet. Audi's latest Piloted Driving demonstrator is based on the R8 E-Tron. It's altogether almost identical to the one we saw in Geneva, packing an electric powertrain to deliver 456 horsepower, 679 pound-feet of torque and a 0-62 time of 3.9 seconds. Only in this case, it can do it all on its own, without any driver intervention. To pull that off, Ingolstadt has fitted this show car with an array of sensors, including a new laser scanner, multiple video cameras, ultrasonic sensors and radar transmitters at both ends – all handled by a central "driver assistance control unit." It's the latest in a series of concept cars that has already included a version of the RS7 Sportback designed to lap the racetrack, and the Prologue concept that drove itself to CES. This concept was similarly unveiled at CES Asia, the Eastern counterpart to the tech expo we usually catch in Las Vegas. Just what the point is in engineering (or buying) one of the best-driving cars on the market and then handing over its operation to a computer, we don't quite get. But at least we can rest easy knowing that Audi is not giving up on performance as autonomous tech turns the driver into just another passenger.

The technology study is one of the highlights of CES Asia, and it brings together future technologies – which relate to lightweight design, high-performance drive systems and functions for piloted driving. The Audi R8 e-tron piloted driving concept car is based on the multimaterial Space Frame of the new production R8. A rear car body module made of carbon fiber reinforced polymer (CFRP) integrates the luggage compartment, which extends the frame structure. The walls of the luggage compartment shell are corrugated, so that they can absorb extreme amounts of energy with little material weight in case of a rear-end collision.
