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.

Audi R8 lines up as safety car for Rolex 24 at Daytona

This weekend a new era begins in American sports car racing with the Rolex 24 at Daytona to kick off the new United SportsCar Championship, the freshly inked union between the Grand Am and American Le Mans Series. There'll be a wide variety of machinery lining up on the grid at the Florida speedway, including race-ready versions of the sports cars you can drive on the road, plus Daytona Prototypes, Le Mans Prototypes and even the DeltaWing. But at the front of the pack will be the Audi R8 5.2 FSI.
That's because Ingolstadt's flagship has been named as the official safety car for this, the 52nd annual Rolex 24 at Daytona. And so the R8 becomes the first pace car pressed into service for the United SportsCar Championship, although the model also paced last year's race (pictured above) when it was under the auspices of the Grand Am series.
The car in question appears to bear little in the way of modifications over the showroom version, save for some requisite graphics and maybe some emergency lighting to make it more visible - because while you wouldn't miss an R8 slicing its way through ordinary traffic on the road, it's another story entirely in a field full of competition machinery. Audi points out that the road-going R8 shares a good 50 percent of its components with the R8 LMS competing in the race, including its 5.2-liter V10 engine that's available this year with a new seven-speed dual-clutch transmission.

2014 Nissan GT-R Track Pack squares off against Audi R8 V10 Plus

The team over at Motor Trend has pitted the new Audi R8 V10 Plus against the Nissan GT-R. While both of the bright red all-wheel-drive supercars are comparably matched in power output, the similarities end there. Audi offers a mid-engine aluminum coupe with a naturally aspirated V10 that spits out 550 horsepower. Nissan shows up with a more traditional coupe equipped with a 545-horsepower twin-turbocharged V6 at the front of the car.
The Head-to-Head video takes both cars to the Streets of Willow Springs in the California desert for some track work with professional racing driver Randy Pobst behind the wheel. After a day at the track, the pair head to the local mountains for some spirited real-world driving. One dominates on the circuit, while the other earns back its credibility in the canyons. We won't tell you which coupe comes out on top, but we think you may be surprised. Follow the link below to watch for yourself.
