Audi may add plug-in hybrid A6, A8 and Q7 to range [w/poll]

Audi could be getting even more diverse with its powertrains for the A6, A8 and Q7, moving beyond offering just gas- and diesel-powered models and adding plug-in hybrid variants of the three luxury vehicles. The report comes from Indian Autos Blog, which spoke to Dr. Ulrich Hackenberg, Audi's research and design chief, who confirmed the PHVs.
The next-generation Q7, due in 2015, will be the pioneer for the full-size PHV movement from Audi, although the A3 Sportback E-Tron (shown above) will precede it. The move toward plug-ins by Audi is a big step, as the German marque has stayed quite firmly in the diesel camp, outside of its racing efforts. It's developed a few E-Tron cars over the years, including a version based on the R8, although it wasn't until recently that production of the electric sports car became serious again.
It's believed that this hesitance to really dive into the PHV market is why Audi sacked former research and design boss Wolfgan Dürheimer, with IAB speculating that his approach was too conservative.

Spyker C8 Aileron to come back with supercharged power?

The new B6 Venator wasn't the only vehicle on display at the Spyker booth at the 2013 Geneva Motor Show. The company still has its C8 Aileron on offer, and Road & Track has word of a potential powerplant upgrade for the long-running machine.
Since its introduction in the year 2000, the C8 has used a 4.2-liter V8 engine sourced from Audi, which, in base form, offers up 400 horsepower. Though it's a great powerpant, that's simply not enough power in this day and age - after all, if a car is going to be called super, it needs to offer more ponies than something as mundane as the Ford Mustang GT.
According to R&T, John Walton, Chief Commercial Officer at Spyker, indicated that a new engine supplier may be in the works. "[The Audi-sourced V8] really hasn't got enough bang for the buck. To be honest, every supercar needs to have something that begins with a '5' today. That's why we're supercharging the car in the future, which will take it to over 500-hp," said Walton.

Audi prices 2014 A8L TDI from $82,500*

During the Los Angeles Auto Show last November, Audi told us that it would be bringing four new diesel-powered models to the United States this year. The first to arrive is the 2014 A8L TDI you see here, and we've now learned that the big oil-sipper will be priced from $82,500, (*excluding $895 for destination).
The whole new range of diesel models will be powered by Audi's 3.0-liter TDI V6, good for 240 horsepower and 406 pound-feet of torque in this application. Of course, Quattro all-wheel drive is standard, and even in the big A8, the diesel grunt will be enough to propel the long-wheelbase flagship to 60 miles per hour in 6.4 seconds (almost a full second slower than the A8 3.0T we reviewed last fall). That said, the A8 TDI should still be a pretty engaging steer, and considering the fact that this thing will reportedly return fuel economy figures of up to 36 miles per gallon on the highway (24 in the city), a slightly slower launch time is well worth it. (The A8 3.0T tops out at 28 mpg highway.)
Elsewhere in the segment, Mercedes-Benz offers a diesel version of its S-Class flagship, retailing for $93,000 and good for fuel economy figures of 21/31 mpg city/highway. By comparison, the A8 TDI seems like a steal, and we'll be interested to see where the forthcoming BMW 7 Series diesel falls into the class of huge oil-burning barges.
