US diesel model count to double for 2014?

While diesel cars are popular on most other continents, these less-complex alternative to hybrid-electric vehicles have yet to gain major traction in the US. As an increasing number of light cars and trucks start to offer these fuel-efficient engines, though, sales are expected to climb as well. While BMW, Mercedes-Benz and the Volkswagen Group (Volkswagen, Audi and Porsche) continue to lead the way, more non-German automakers like Mazda, Nissan, Chrysler and General Motors are starting to get serious about diesel in America.
TheDetroitBureau.com reports that the 2014 model year will see the number of diesel vehicles offered in the US double to about 40 nameplates, but the news gets even better for fans of these torquey and efficient powerplants. LMC Automotive has released data about future expectations of diesel cars in the US, and it predicts that sales should be very close to one million units in 2015 (up from an expected 600,000 units this year). By 2018, LMC's calculations suggest that sales will more than double from this year's expected totals accounting for almost 8 percent of new light-vehicle sales.

2015 Audi S8

You've gotta hand it to the Audi A8. Last year, Mercedes-Benz launched the truly stunning S-Class, putting the rest of the high-dollar luxury flagship class on notice. With the brand-new S-Class turning heads and garnering all sorts of praise from the automotive press, classmates like the BMW 7 Series, Jaguar XJ and Audi A8 started to look, well, old. But Audi didn't see fit to just let its big sedan carry on and let the Mercedes take the cake.
So when Audi refreshed its A8 line for the 2015 model year with only minor updates, I kind of shrugged it off as just a quick way to keep the big sedan fresh until an all-new, hopefully S-Class-trumping version arrives. But then I drove the S8 pictured above, and I'm no longer so sure the Merc's shadow is as big and imposing as it once was.
Spoiler alert: the Audi S8 is simply fantastic.

Audi SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.
