Audi E-tron

Audi E-tron

  The Audi E-tron concept is an electric sports car that debuted at the Frankfurt motor show in 2009 and refreshed at the 2010 Detroit show. Audi plans on producing 1,000 units for 2012, the E-tron concept is powered by a purely electric drive system that consists of four individual motors, two at the front and two more at the rear of the bright orange BEV. All together the electric motors combine to create a maximum output of 313 HP and an astounding 3,319.03 lb-ft of torque propelling the E-tron from 0 to 60 MPH in a very appropriate 4.8 seconds.

Despite the various high-speed crashes which took place at the recent 2012 24 Hours of Le Mans , Audi managed to come out on top for the 11th time in 13 years. With both Toyota LMP1 cars crashing out in the early stages of the race, one could argue that Audi was destined all along to take victory.

However, one could never have imagined that Audi managed to wrap up all three podium places with its incredible R18 race cars, two of which are e-tron Quattro-diesel-hybrids while the other two who finished in 3rd and 5th were the more conventional R18 Ultra diesel-powered racers.

Driving the victorious Audi R18 e-tron was Marcel Fässler, André Lotterer, and Benoît Tréluyer. This victory marks a historic day in Le Mans history as the victorious car is the first diesel-hybrid to ever sit upon the top step of the podium and could help pave the way for more fuel-efficient LMP1 racers.

Audi board member Rupert Stadler stated, "By achieving this further success at the world’s most important endurance race our engineers demonstrated their high technological expertise in a particularly impressive way. With the e-tron Quattro in combination with ultra-lightweight design, we put a completely new technology on the grid and immediately won with it – this cannot be taken for granted by any means, particularly here at Le Mans."

It’s inevitable that Audi has already turned its attention to next year’s 24 Hours of Le Mans, where we expect to see even more hybrid-diesels contesting.

Audi doesn’t mind pushing the envelope a little further than most people would and has proven that with the release of a new Le Mans race car. The racer is called the R18 e-Tron hybrid quattro, a four-wheel driven diesel hybrid race car that’s set to compete at the legendary 24 Hours of Le Mans in France on June 16 and 17, 2012.

Working under the same principles as that of the Porsche 911 GT3 R Hybrid , the R18 e-Tron hybrid quattro uses kinetic energy that’s recovered whenever the car brakes, storing that energy in the flywheel accumulator as electricity before being sent back to the electric motors on the front wheels. The motors take car of the front of the vehicle, while the rear wheels get their power from the car’s 510-horsepower V6 TDI engine. The only difference between the aforementioned Porsche and the R18 e-Tron hybrid quattro is that the latter is considered a mild hybrid, using a petrol engine along with electricity.

Since the car uses a heavy hybrid system, Audi went and designed the race car’s gearbox using carbon fiber composite housing, alleviating some of the weight brought about by the complicated drivetrain.

Before it struts its wares in Le Mans, the car will be put through the paces on May 5th at the 6-hour race at Spa-Francorchamps in Belgium where it will be raced by Allan McNish, Dindo Capello Tom Kristensen and Benoît Tréluyer, André Lotterer and Marcel Fässler.

UPDATE 06/07/2012: Audi has unveiled a cool promo video for their brand new R18 e-Tron that will compete at the legendary 24 Hours of Le Mans race on Saturday, June 16th-17th 2012. The video presents Audi Audi ’s racing evolution, going from turbocharged direct injection (TFSI) up to turbo diesel (TDI) engines and the new e-tron.

Audi A1 e-tron Concept

Audi has been experimenting with the electric-car market for a few years and officially unveiled plans for the A1 e-tron and an electric-powered A2 recently. It does not look like either one is going to happen any time soon, according to a report from Car.

The A2 electric was slated to be released in Europe, where high-efficiency diesel and gasoline engines that get upwards of 60 mpg reign supreme. These markets are tough enough to crowbar in an electric model, but add in the fact that the A2 was expected to carry a €40,000 ($50,000) price tag, and you get a model that was bound to fail in the European marketplace. Combine that price point with the fact that the Nissan Leaf , with its far lower €25,990 ($32,500) price tag, only saw 3,000 units leave showroom floors in 2011, and Audi wisely saw this as a fruitless journey.

The entire A2 line will likely continue as expected, sans the electric model. This leaves a gasoline and diesel model as the only drivetrain options.

The A1 e-tron reportedly is meeting a similar fate, but for different reasons. The A1 e-tron is being axed due to extravagantly high production costs. This car was planned to be similar to the Chevy Volt , as it was going to have a gasoline engine to extend the range of its electric motor by charging the batteries via a Wankel (rotary) engine.

Though this is a tragic way to abruptly cease the development phase for an electric lineup, we cannot blame Audi for its choice. Electric cars just are not selling well in the European markets and having one priced nearly double its closest competitor and another one with climbing production costs just isn’t smart business.

Audi is further expanding its e-Tron line-up with a new A6 L e-Tron concept at the 2012 Beijing Auto Show. This decision really shouldn’t surprise anyone considering people in the Chinese market love their large cars, but want efficiency in their models as well. The new A6 L e-Tron Concept serves up the perfect combination the luxury and the practicality of an A6, and a range of 49.71 miles on pure electric power.

Like all the other e-Tron models, the new A6 L e-Tron concept combines a 211 HP 2.0 TFSI engine with a 95 HP electric motor. The electric motor takes its power from a liquid-cooled lithium-ion battery located in a collision-protected space at the rear of the vehicle.

The concept was built on an ultra lightweight principle that combines 10% aluminum with carbon fiber-reinforced polymer (CFRP). The interior is almost similar to a standard A6 , except that the power-meter replaces the tachometer that offers the driver the info he needs.

One of the biggest allures people have of supercars is the ear-splitting noise these cars produce. After all, nothing speaks to a car’s power than all those ponies working in harmony to produce a roar like no other.

But what happens with a car like the Audi R8 E-Tron , a supercar that’s powered by silent electric motors?

In the case of Audi , it involves a few compromises. In this video, Audi talks about the challenges of producing that emotional sound supercar owners love on a car that’s run by electricity. The solution, as far as Audi engineers are concerned, was to develop a synthetic sound signature that can be played with a loudspeaker attached to the car’s undercarriage.

Take note of the word "synthetic" because that in itself means that the sound is fabricated and not directly derived from the engine. Nevertheless, the objective with the "E-Sound" was to generate enough noise to allow drivers to enjoy the thrills of a supercar with an electric powertrain.

Check out the videos - one of which you can find after the jump - to find out how Audi accomplished giving the Audi R8 E-Tron the supercar-like sounds similar to its gasoline-powered siblings.

When Audi unveiled the Urban Concept at the 2011 Frankfurt Motor Show, we honestly believed it was a huge waste of time because there was no chance Audi would ever actually put it into production. Turns out, we were absolutely wrong.

Audi has just announced that the Urban Concept will indeed go into production and that it will be limited to only 999 units. Sales will begin in 2013 at a starting price of £8,800 or about $14,000 at the current exchange rates.

The production version will feature two electric motors powered by a lithium ion battery and a single-speed transmission. The model will be built using carbon-fiber reinforced plastic and will weigh only 1,058 lbs. This will help the car sprint from 0 to 60 mph in 6 seconds and hit a top speed of 60 mph. It is also expected to see an average range of 30 miles.

This will, by far, be the strangest production Audi produced as of now.

Next to the Quattro concept , Audi has also unveiled at the Paris Auto Show the e-tron Spyder, a concept rumored to preview the future R4 sports car. But compared to the previous E-tron concept, this one is powered by a turbochargers 3,0 Liter TDI engine with an output of 300 HP, combined with two asynchronous electric motors with a total output of 88 HP. The result is a sprint from 0 to 60 mph in 4,4 seconds and a top speed limited to 155 mph. All this while delivering a fuel economy of 106.92 US mpg.

The E-tron Spyder measures 1.81 meters (5.94 ft) wide, just 4.06 meters (13.32 ft) long and only 1.11 meters (3.64 ft) in height. It features a wide central air inlet, single-frame grille, adaptive matrix beam headlight modules with three-dimensional clear glass covers carbon inserts in the front and side windows and of course 20-inch wheels.

The interior gets a large, display with integrated MMI functions and flanked by two round dials; racing-inspired lightweight bucket seats, contrasting colors and high-quality materials.

UPDATE 10/18/11: The Audi E-Tron Spyder was recently spotted at Mulholland Drive in California doing some test work. And today Audi has unveiled a new video showing the concept in action in Malibu. Also, we have added new photos of the car, which you can check out by heading to the gallery.

Press release after the jump.

A few days ago, a mysterious Audi prototype was spotted in Berlin decked in camouflage, leading to the proverbial question as to what kind of car it was. Fortunately, the mystery didn’t last long.

The German automaker has released the first details of its new Urban E-Tron Concept that will be gracing us with its presence at the coming Frankfurt Motor Show . It took a while for Audi to release all the information of the Urban E-Tron Concept, but thankfully, did so just in time for the opening of Frankfurt, complete with all the performance numbers that might not tickle the fancies of those looking for some speed to go with the cool city car concept.

UPDATE 11/02/2011: We thought the Audi Urban E-Tron Concept was a huge waste of time because there was no chance Audi would ever actually put it into production. Turns out, we were absolutely wrong.

Audi has just announced that the Urban Concept will indeed go into production and that it will be limited to only 999 units. Sales will begin in 2013 at a starting price of £8,800 or about $14,000 at the current exchange rates.

You have to excuse us for doing a little double-take on Audi ’s new Frankfurt-bound Urban Spyder Concept. We actually thought that this was the same concept as the Urban E-Tron Concept that we introduced a few days ago. As it turns out, they’re two completely different models. Who knew, right?

The overall look of the car is completely similar to that of the Urban E-Tron Concept, including stand-out features like the free-standing 21” wheels and the surrounding plates that incorporate those strips of LED lights. However, where the E-Tron has a sliding roof and doors, the Spyder Concept doesn’t have a roof at all and instead features a low, continuous window area with its doors opening upwards diagonally.

As for the interior, well, we don’t see anything different either. Both models carry a 1+1 seating configuration with each of the seats being made from carbon fiber-reinforced polymer (CFRP) to provide supreme sturdiness in a lightweight set-up.

Finally, the Urban Spyder Concept also runs on two E-Tron electric motors that provides the power for the car and combined with a lithium-ion battery pack that supplies the energy.

That’s about as much as we’ve been told for now. But rest assured, we’ll share more details as soon as they become available.

Audi has taken their E-tron concept a step forward with the unveiling of the E-tron A3 concept - a compact car featuring a powerful electric motor and a liquid-cooled lithium-ion battery. Although the concept looks almost identical to the production A3 , there are a few elements that will help distinguish it. The concept has received a revised instrument cluster, leather Alcantara seats, a heated windshield, and an optimized air conditioning system.

The most important difference between the two concepts can be found in the powertrain. As a hybrid concept, Audi decided to use a different engine than the one found in the A3 Sedan Concept. Instead of the 2.5-liter turbocharged engine of the A3 concept, the E-tron version has a slightly less powerful 1.4-liter TFSI turbocharged gas engine that doesn’t come close to the output the former has.

Of course, being a hybrid concept, performance takes a back seat to fuel efficiency and that’s where the E-tron A3 Concept has the upper hand over the gasoline-powered A3 Concept.
