1,682 miles in a 2014 Audi A8 L TDI - Part 1

We're going to skip the joke - because this isn't one - and get straight to the punchline: If the forthcoming 2014 Mercedes-Benz S-Class looks like it will lead the segment in interiors, the 3.0-liter turbodiesel in the 2014 Audi A8 L TDI takes the head of the table when it comes to engines.
After joining Audi for the 12 Hours of Sebring, we stood in the parking lot of The Inn On The Lakes on Sunday morning, our thousand-yard stare interrupted by the Citgo gas station across the street. We had one key, three bags, one white A8 L TDI, something like 17 gallons of diesel in the tank and one week to burn through it. For the purposes of a Quick Spin, we could have simply traipsed around the central Florida outback, all citrus, dusty scrubland and diners lifted from Cronenberg films, made short work of measuring the refinement and potential rarefaction of the oil burner under the hood and made our way back to the Orlando airport.
But dear readers, where would the adventure be in that?

Audi exec denies plans for turbo R8

Sometimes smoke doesn't lead to fire. Rumors indicated Audi might drop a turbocharged engine into the latest R8, but now a top executive is throwing a bucket of cold water onto the burning speculation. "The performance potential of this current engine means we don't need to even look at turbocharging at this point," Jurgen Konigstedt, Audi development boss for V6, V8, and V10 engines, said to CarAdvice. He also said sticking with natural aspiration offered a better sound and sharper throttle response than going with forced induction. "There is less emotion with a turbocharged engine," he said. Konigstedt admitted there was a serious discussion about turbocharging the R8. The argument just didn't win out. "If we feel that people absolutely want a turbocharged engine, then we will have to consider it," he said to CarAdvice. Audi just launched a new generation of the supercar. The 2017 R8's 5.2-liter V10 will be available in two tunes: with 540 horsepower in the standard coupe or 610 hp in the Plus. Rumors have persisted about a smaller, forced induction powerplant at the bottom of the range. Some reports suggested a twin-turbo V6 behind the driver, but others said the electrically supercharged 2.5-liter inline five was a candidate. The reason for the entry-level addition was tied to lowering the taxes on the R8 in markets like China. Related Video:

The VW emissions carnage assessment with an upside

Bombs cause destruction. Even if they're intelligently guided and pinpoint, there's always collateral damage. The strange Volkswagen brew, which is still spontaneously combusting in plain sight, will result in aftershocks for years. And the professional end of the corporation's top leadership will not be the only casualties. Blows are striking shareholder confidence, the residual value of the cars involved, consumer confidence, and the German economy itself. A hard rain's going to fall elsewhere, too. Here are just four damage assessment areas. The High-Compression Past and Low-Compassion Future of Diesels Despite European and especially German manufacturers' high belief that diesel engines were a way to light-duty automotive salvation, VW's scandal started the last nail in the fuel's coffin. Regulations both in the U.S. and in Europe for particulates and nitrogen oxide (NOx) are getting much harder to meet, and this is at the very core of VW's deception. Even with the high-cost exhaust after-treatment systems, sky-high fuel pressure, and sophisticated electronics, the inescapable NOx realities won't be washable by technology in an affordable way. German engineering pride will have to work a real miracle to meet these looming regs and the stain of VW's scandal did the whole diesel movement no favors. Perhaps not so ironically, the E.U. adopted more stringent emission standards this year, which closely mimic the U.S. Tier 2, Bin 5 figures phased in for 2008. Indeed, when VW announced it was able to meet the stringent US NOx emissions standards in 2009 for its diesel engines without urea injection as an exhaust after-treatment, it was a particularly high point of engineering pride for the company. No other manufacturer had figured out how to do so. One Honda official at the time remarked that they had simply no idea how VW was achieving this feat and Honda couldn't come close. Well, neither could VW. On a macro scale, European cities are also starting to face government fines for air quality violations. This is forcing those cities to find various ways to cut smog-related causes like tailpipe emissions. In fact, Paris has gone to the length of restricting car use on a sliding scale when smog persists, while electric cars are free to roam. France's longer and larger plan is banning diesel fuel for light-duty transportation entirely. But why was there a frothy focus by the European manufacturers on diesels in the first place?
