Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.

Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

Audi perfecting drool-worthy RS3 hot hatch

A sure-fire way of adding excitement to any Audi is removing the "A" from its model name and replacing it with "RS." Take the RS4, RS5, RS6 and RS7 as proof of this fact. Of course, the transformation from "A" to "RS" wouldn't be complete with a huge bump in power, a far more sporting suspension, enhanced brakes and a more aggressive styling treatment. That process appears to be well underway with the next RS3, which has once again been spotted testing in Germany. The larger wheels (the styles are mismatched, but the sizes look similar) are a good giveaway, as are the larger brakes and more aggressive front bumper, which sports larger intakes. The rear bumper has been modified, although we can't quite tell if the RS line's tell-tale oval exhausts have been fitted. In the past, the RS3 mules we've heard have boasted the distinctive exhaust note of a five-cylinder engine. This particular car, though, has a more conventional exhaust note, of the sort you'd expect from a high-powered four-cylinder. Expect around 400 horsepower and Quattro all-wheel drive, with power distributed likely through some form of S-Tronic dual-clutch transmission. Take a look up top for our gallery of spy shots, and keep an eye open for the RS3 in October, when it's expected to debut at the 2014 Paris Motor Show.
