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.

Audi planning RS Q7 performance crossover

Audi resisted getting into the crossover market altogether until it launched the original Q7 in 2005, and held back from producing a performance crossover until it caved first with the SQ5 and then with the RS Q3, both in 2013. And now that the tide has washed over it, Ingolstadt's next plan, according to Top Gear, is to launch a performance version of the new Q7. Though it remains unclear whether it would carry the S or RS badge, the performance-oriented version of the new Q7 will surely benefit from the hundreds of pounds in excess weight Audi managed to trim off the latest model over the one it replaces. Also unclear is whether said hi-po Q7 would go with a diesel or a gasoline engine. The diesel option would more likely go the S route than the full RS, but wouldn't be likely to make it to the States if it were only offered as a diesel. With the SQ5, it's worth noting, Audi offers a TDI diesel version in Europe and a gasoline TSI in North America, so we wouldn't be surprised to see it take a similar approach with the larger model as well. Whatever it does pack under the hood, though, the SQ7 or RS Q7 would be facing some stiff competition from the likes of the Mercedes GL63 AMG, BMW X5 M and Range Rover Sport SVR – not to mention corporate cousins like the Porsche Cayenne Turbo and upcoming Bentley Bentayga – while giving the Volkswagen group a bigger slice of that exclusive but expanding pie.

VW says it has sold over 100,000 TDI diesels in America this year

Volkswagen Group of America has lit oil-burning fireworks to celebrate the sales of more than 100,000 TDI Clean Diesel vehicles in the US between its VW and Audi brands this year. According to VW, that means it is responsible for more than 75 percent of diesel-engined cars and SUVs sold here - perhaps not surprising when the two brands offer a total of 12 diesel models.
What might be surprising is that the number of diesels isn't far off the estimated sales of 90,000 battery electric vehicles and PHEVs, with 15,000 of those accounted for by the Tesla Model S, another 12,000 or so being the Toyota Prius PHEV.
VW's keen to play up the ease of making diesel part of your life, stressing that it doesn't need any change to the refueling infrastructure and that "this is a technology delivering real answers to society's concerns about fuel consumption and greenhouse gas emissions without compromises."
